The Challenge for Our Schools: Thomas Friedman and Education

Retort by Harry Keller with a distilling retort on the left

Today, in his New York Times Op-Ed (Webcite alternative), Thomas L. Friedman made this comment:

Good-paying jobs don’t come from bailouts. They come from start-ups. And where do start-ups come from? They come from smart, creative, inspired risk-takers. How do we get more of those? There are only two ways: grow more by improving our schools or import more by recruiting talented immigrants.

This respected economist and commentator has closely linked our education system to our future success as a nation. He also argued for more immigration, more H-1B visas with longer durations. Continue reading

Social Networking and the Secondary Student

Meeting the Needs by John AdsitMost discussions on this site dealing with the use of social networking in education are devoted to post secondary education. This column will look at the unique challenges of using any form of social networking in secondary education. The differences are significant, partially because of the ages of the students and more importantly because of the role of boards of education. Social networking in the secondary level has to solve some problems if it is to be used successfully. Continue reading

Thomas H. Huxley on Teaching Science

Retort by Harry Keller with a distilling retort on the left
Frederick W. Westaway wrote on many subjects, especially about teaching science. He wrote the definitive volume, Scientific Method, Its Philosophy and Its Practice, for example. In 1929, he spoke clearly to us today about science education in his book, Science Teaching. He quotes Thomas H. Huxley, also known as “Darwin’s bulldog,” at length about science education. This Huxley quote from Westaway’s book dates to 1869! Continue reading

iPad – Breakthrough or Misstep?

The iPad debuts today, and, as an educator, I can’t help but wonder if this will be the breakthrough portable communication device that will hasten the release of students and teachers from the grip of classroom walls. Continue reading

Headphones, Computers, and the Web

Jim ShimabukuroBy Jim Shimabukuro
Editor

Note: The primary reason for selecting this subject for the second article in ETC’s “Extracurricular” series (see John Adsit’s “The Great Technology Controversy Follows Me into the Caves“) isn’t so much to share information about what I consider an enjoyable hobby but to underscore the fact that the entire pastime is built on computers and the web. All of the equipment was researched and purchased on the web – out of necessity because, for the vast majority of enthusiasts, it’s not available in stores within driving distance. I think I can fairly say that this hobby wouldn’t be possible without the internet and that it owes its survival and growth to a community that’s defined virtually rather than geographically. -js Continue reading

Threat of Lawsuits on Social Networking Sites

Meeting the Needs by John AdsitOne of the dangers we face in using social networking sites is our lack of control over them, their content and the way participants interact. Because the law on this is still emerging, we face the potential for unknown legal repercussions. An example of this has just come about as a social networking site devoted to scuba diving, scubaboard.com, has been sued, along with over 100 of the people who post on it, for content that would be considered tame in most social networking sites.

Thoughts on ‘Innovating the 21st-Century University: It’s Time!’

Tom PreskettBy Tom Preskett

I’ve read and re-read Innovating the 21st-Century University: It’s Time! by Don Tapscott and Anthony D. Williams (Educause, 2010) to try and absorb its key messages. Here are some quotes from the article, followed by my comments.

Universities are losing their grip on higher learning as the Internet is, inexorably, becoming the dominant infrastructure for knowledge — both as a container and as a global platform for knowledge exchange between people — and as a new generation of students requires a very different model of higher education.

Tech Support – Abandon All Hope Ye Who Enter

Meeting the Needs by John Adsit
Advocates of technology in education, especially those who, like me, advocate for online education, need to consider the problems that the modern concept of tech support can cause. Tech support within a school campus is very different from tech support for the student or teacher working at home. If I were either an online student or teacher during the past year, I would have had serious problems due to technical difficulties, and the nature of these is such that it brings me real concern for anyone in such a situation in general. Online programs will have to consider processes to deal with this. Continue reading

I made my first online class in 1995, and since those days much of my life has been spent trying to convince nonbelievers that computers could improve student learning if used properly. Those years were filled with many less than pleasant arguments, and like many people I looked to my recreational life to get away from such battles. Unfortunately, I now find that my chief area of recreation, scuba diving, is filled with those same battles. The controversy of my work life has doggedly pursued me into my recreational life.

Do You Speak Livemocha? An Interview with Clint Schmidt

Stefanie PankeBy Stefanie Panke
Editor, Social Software in Education

Livemocha is a social network service that supports language learning through audio-visual lessons and peer tutoring tools. Launched in September 2007, the platform has over 5 million registered members from over 200 countries. Lessons are provided for 36 different languages. While the standard lessons are freely accessible for registered users, the platform also offers “premium content” for a fee. Livemocha is more than just “Rosetta Stone on the Web.” A unique selling point of the educational Web community is its collaborative approach to language learning: Members of the Livemocha community do not only learn a foreign language, they also tutor other community members in their native language. Users are encouraged to form learning tandems and offer feedback on their partner’s speaking or writing exercises. The Livemocha platform supports this peer learning practice through comment features, voice recording and social awareness tools. Continue reading

Successful Learning: A Matter of Both ‘What’ and ‘When’

Meeting the Needs by John AdsitI recently addressed the value of using learning objects to address student needs for prerequisite skills in online instruction. I suggested developing a library of learning activities that could be tapped into whenever a student had an identified learning need that was interfering with present learning. Not too long ago an online education company considered the idea of using independent learning objects of this kind to create new courses just by mixing and matching the objects as needed. They also considered building a course entirely with such lessons, letting students select the lessons they needed in the order they felt they needed them. This, they felt, was the epitome of student-centered learning. Continue reading

Textbook Tweets – Integrating Twitter into a Telecommunications Design Class

Dr. Carrie Heeter, a professor of Telecommunication, Information Studies, and Media at Michigan State University has been integrating Twitter into her graduate Design Research class this spring in two very different ways. She is moderating a class Twitter ID (@tc841) set to follow experts in the field. Heeter retweets particularly important content to students and to the vibrant professional community of design researchers on Twitter.

Heeter is using Twitter in an unusual way to enhance live class discussions of assigned readings. She calls it “Textbook Tweet Time.”

As a graded part of live class participation, Heeter’s students are assigned to come prepared to tweet interesting insights they gleaned from the week’s readings from the Twitter ID they created for class participation (this can be their personal Twitter ID or one created exclusively for class). Using the PowerPoint Twitter tool from SAP, Heeter configures and projects a PowerPoint slide to search for the hash tag #tc841read. The search is continuously updated so new tweets show up within 10-20 seconds.

Dr. Carrie Heeter

Students must include that hash tag in the tweet in order for it to show up on the slide (and in order to receive credit for participation). The PowerPoint Twitter Tool can be toggled between two alternate formats – one shows the 9 most recent tweets in dialog boxes, along with the twitterer’s ID and photo. The alternate photo shows the most recent 18 tweets. The examples below are from Textbook Tweet Time about Will Wright’s chapter, “Sim Smarts,” in Design Research by Brenda Laurel.

As tweets appear in class, Heeter calls on the tweeters to describe their post. The class discusses each post, then moves on to another tweet. The class tweets about and discusses one chapter at a time, to limit number of tweets and to focus the discussion.

Heeter finds that “the tweets give each student a platform, almost like handing them a microphone. The students explain and expand upon their tweet, and discussion ensues.” The tweets focus class discussion and ensure 100% participation (in this small graduate class). There is a permanent record of the tweets, which facilitates grading of live class participation and motivates attention to the readings before class.

Learners can also view the search results for #tc841read on Twitter search (located at http://search.twitter.com). This view does not limit the number of tweets that are returned unlike the PowerPoint tool (shown above). Heeter subscribes to the RSS feed for that Twitter search, creating a permanent record of the class tweets on her desktop. Heeter says, “Because I can search and archive the tweets, grading classroom discussion becomes more systematic, thorough, and objective. I gain a sense of what matters from the readings, and some feel for how deeply different students are delving in to the readings. The tweets motivate preparation for class and then serve to reinforce the important points; and they give each student a turn.”

Twitter is a public space, leading to the potential for privacy concerns. In Heeter’s design, the students can use their personal Twitter account for class or they can create a unique twitter ID just for TC841. She says, “They control their anonymity in their choice of twitter ID.” For example, one student’s Twitter ID is six letters, all consonants and unpronounceable. Another student is a deceased movie star. Still others use their real names.

Some students post a picture of themselves as their Twitter icon while others post a graphic or picture of something other than themselves. Still others are simply a variation on the default Twitter icon – a white bird silhouette with a color background. “I have one orange student, one purple, and one light blue,” says Heeter. “I know the Twitter ID that each student is using for class so I call on them by their real name (or for fun, sometimes by their silly Twitter name). Their tweets are public, but depending on the set up choices they have made, they are more or less anonymous.”

By navigating to http://search.twitter.com and searching for #tc841read, Heeter can click on the feed for the #tc841 query button to have a folder in her default RSS reader collect and save all textbook tweets.

Heeter feels that using tweets for classroom discussion and collaboration is working well, though she notes that “for larger classes I would need more control.” As it stands, with the number enrolled, she finds “this particular interface happens to be perfect as is right now in this class.”

Heeter lives in San Francisco and teaches in East Lansing. The design research class is a hybrid class with between one hour and 90 minutes of live class and the rest online. Heeter participates via Skype and Breeze connect. Students can either come to the classroom or Skype and Breeze from any remote location. Of course, the instructor need not be remote for Textbook Tweet Time to be an effective component of synchronous class discussion.

‘Digital_Nation’ – Two Reviews

encounters80Introduction: This encounter was suggested by Lynn Zimmerman in an email message to Jim Shimabukuro. It is based on Rachel Dretzin and Douglas Rushkoff’s Frontline special, “Digital_Nation: Life on the Virtual Frontier,” published in video format on 2 Feb. 2010. Jessica Knott and Jim have responded to the 90-minute online program with the articles below. All are invited to comment.


Digital Nation – Geeks May Be Normal, but Are They Listening? by Jessica Knott: With technology comes responsibility. Be it a conference back channel or a course lecture, expectations for use must be set and outcomes made explicit. Ample opportunity for exploration and self-reflection is crucial in any learning environment, and technology can facilitate this in ways that were impossible even 15 years ago. It is important, however, not to lose ourselves in the technical abyss. We are not educators of technology, we are educators harnessing technology. [click here to read the full article]

Social Networking for Academics: An Interview with Ijad Madisch, CEO of ResearchGATE

Stefanie PankeBy Stefanie Panke
Editor, Social Software in Education

ResearchGATE was founded in May 2008. The platform aims to create an international network of scientists and has been quite successful so far. ResearchGATE has 250,000 members worldwide and grows with a rate of approximately 1000 new member registrations daily. The features are targeted to a scientific audience, for instance, supporting the “self-archiving” of publications.

For ETC Journal, I interviewed Dr. Ijad Madisch, the platform’s co-founder and CEO. Ijad spends most of his time in Boston, where he works as a radiology researcher at the Massachusetts General Hospital of Harvard Medical School. He studied medicine and computational science at the German University of Hannover and the Harvard University in Boston. He received a summa cum laude for his doctoral thesis on virology and was awarded the 2008 doctoral research award from the University of Hannover.

The interview offers a look behind the scenes of a social networking start-up.

Dr. Ijad Madisch, co-founder and CEO of ResearchGATE

SP: Please describe the purpose and main idea of ResearchGATE. Does the character of the Web site reflect the academic background of its founding fathers?

IM: ResearchGATE – scientific network is a custom designed online platform and community where researchers and scientists connect with each other to communicate and collaborate: increasing efficiency, interdisciplinary collaboration and the overall effectiveness of research. The academic background of the founders was the driving influence for the Web site. As active researchers, scientists, and programmers we were seeing how the concepts of web 2.0 were changing the way we use the Internet, and we wanted to apply this to the world of science where we felt there was an opportunity to build a new kind of online science community.

SP: How has the platform evolved over time? What were important milestones?

IM: By listening to the needs of researchers and scientists, the platform has evolved to be a dynamic and active community with over 250,000 members. Important milestones include Self-archiving and supporting the open access movement, the Research and Science Job Board and our last innovation, a community generated Research blog, which comes with a new concept, so-called “microarticles.”

SP: How does social networking in general and ResearchGATE in particular fit into your everyday working routine? Has it changed your approach to teaching and/or research?

IM: Social Networking is both a part of my daily life as a researcher and doctor. I can find collaborators easy and fast by searching for individuals with specific research skills. This allows me to be efficient in keeping up with researchers and colleagues in and around my field, and I am able to easily search for papers and articles that are relevant and current. Social networking allows me as a teacher and researcher to manage literature, to make contacts in my field, to join online discussion groups and to discuss lecture topics with a student group.

SP: Who are the typical users of ResearchGATE? What are the benefits for teachers and students?

IM: Our typical user is someone who is involved in some aspects of research, be it academia or corporate. If we focus on the educational context, benefits for teachers and students include: custom built semantic search, literature organization, suggestions for relevant papers and contacts to subject experts, the ability to form specific discussion groups, share documents online, access full-text papers that have been self-archived by other ResearchGATE users, keep up to date with science through our news site.

SP: What should be my first steps to get involved? Can you describe a beginner’s scenario and the pathway to becoming an expert user of academic networking?

IM: Let me give you a brief overview, those interested in more detailed information should check out the ResearchGATE Help.

Obviously, the first step is to sign up for an account on ResearchGATE. All you need is an email address. Then, fill out your profile information, including a list of publications, associations and research interests. A good way to create more interest in your profile page and increase the visibility of your academic achievements is to self-archive your published papers. One you have done that, it is time to show and tell: Add other community members as personal contacts and invite your colleagues to join you on ResearchGATE. To find new contacts, join groups and participate in discussions which are relevant to your field of research. In addition, you can search for relevant papers and add them to your online library where you can efficiently manage literature. The next step of community building is to create your personal ResearchGATE blog to share your ideas, comments, experiences and science news with your followers or try our new feature and write microarticles about your published work.

SP: ResearchGATE is quite unique in its support of the open access movement. Can you describe how specifically the platform’s open access components work?

IM: ResearchGATE encourages members to support the OA movement by self-archiving their published work through a simple process of uploading a full-text version of their paper. This is part of the “Green Route to Open Access” as many publishers allow authors to self-archive a version of their work on a personal Web page. Each ResearchGATE member profile acts as a personal Web page. This makes the open access publishing being in accordance to publishers’ guidelines. As well, our self-archiving platform is connected to Sherpa Romeo, which will automatically list the self-archiving guidelines for the specific journal the member’s work appears in.

SP: Why is open access important to you as a medical researcher?

IM: Open access is extremely important to me as a medical researcher – often important papers require expensive subscriptions to online publishers. Depending on the institution you’re associated with, you may or may not have access to these papers. I think the kind of information that is held in research papers should be easily accessible especially in the medical field where doctors and researchers need to be aware and up to date on the latest theories and findings.

SP: How do you foster interaction with the members of the ResearchGATE community?

IM: First, we are encouraging members to join groups and discussion related to their research – ResearchGATE automatically recommends groups that might be relevant to the individual user. Second, we support discourse by providing members with the option of starting a personal blog and involve themselves in discussion on other members’ blogs. Our users can upload and share research findings and results, and they will receive personalized recommendations to check out resources provided by other members who work in the same field or have similar interests.

SP: Let’s talk about your business model. So far, is ResearchGATE a success?

IM: ResearchGATE is a great success for us so far. Our business model is based on slow but steady growth. It is important to us that areas of revenue are aligned with the community goals. We are focusing right now on the career section: job market information, job opening alerts, résumé postings, etc.

SP: When you look back on almost 20 months of running an academic social networking platform, what are your personal lessons learned? Would you do it again?

IM: First, business is about friendship: Don’t believe that your friends can’t empower you. Friends give more honest advice than consultants, support your cause with greater passion than any employee, and are more likely to tell you when you screw up than any business partner.

Second, if you have a clear goal, you’re more likely to reach it: Don’t get distracted by the bumps along the road but focus on the big picture. What is it that you really want to accomplish? Once you’ve set your mind on something, you’re halfway there.

Third, the wisdom of the crowds is more powerful than you are: It’s easy to think that you have some unique intellect that’s given you an answer the rest of the world disagrees with, but chances are, you’re just wrong. When groups of intelligent, dedicated people focused on the topic at hand build a consensus, chances are they really have arrived at the best decision, even if it’s not the one you would otherwise make.

Fourth, embrace community and listen: Too often companies and their employees boast about how customer-centric they are, but they really aren’t. If the customer is the cornerstone of your company – as they should be – you should be building a community among your customers that enables them to influence product development. Let them lead your company as if each customer is a key executive.

Would I do it again? I would absolutely do it again!

Learning Styles and the Online Student: Moving Beyond Reading

Lynn ZimmermannBy Lynn Zimmerman
Editor, Teacher Education

In his January 30, 2010 article, Reading Ability As a ‘New’ Challenge for Online Students, Jim Shimabukuro focused on the connection between reading skills and the online environment. As a teacher educator, this issue is one of my concerns about online education.  In today’s online environment those who communicate and process well by reading and writing are at a definite advantage, while students who learn and process in other ways may not adapt as easily. As Jim pointed out – reading is more than being able to decode and comprehend words. Therefore, if we want to meet the learning needs of all students, we have to take different ways of learning and processing into account, and use a variety of strategies and techniques to promote learning (see Howard Gardner’s webs site about Multiple Intelligences http://www.howardgardner.com/MI/mi.html or the Illinois Online Network’s page called Learning Styles and the Online Environment at http://www.ion.uillinois.edu/resources/tutorials/id/learningStyles.asp )

Part of the answer is having technology that will handle audio and video, which can be a challenge. For example, this semester I am teaching a class online that I usually teach as a hybrid. There is a video clip that I usually show my students and after determining that I would not be infringing copyright, I enlisted the aid of our AV people to put the clip into a format that my online students could view. It works great if you are using one of the computers in their computer lab. However, for some reason that no one can pinpoint, the link will not work properly everywhere. On the computer in my office on campus, I get audio only. At home, I get nothing. My students are supposed to watch this clip next week and I have no idea how many of them will actually be able to view it, despite the best efforts of our AV people to make it available in a variety of formats.

On a more positive note, I did have success using Adobe Presenter to record audio onto the PowerPoint presentations that the students will view. In this way, those who prefer to listen can do that and those who prefer to read can read the notes that are part of the presentation. I also located some YouTube videos that I assigned instead of readings on a couple of topics.

However, I have not yet come up with a plan for the students’ being able to produce audio or video clips instead of writing. There are options, of course, but again access to technology can be an issue. I considered asking students to upload an audio or video file as one assignment, but rejected that idea because of the possible problems with technology. I want the students to spend time on the content, not on learning new technology. The best scenario, as far as I’m concerned, would be to have one or two synchronous online discussions using Skype, or similar technology so that students could talk to one another. Maybe next, I can develop something along that line.

To be most effective as a learning tool, online technology has to evolve to the point that students can readily use the skills they already have in addition to (perhaps, while learning) these new skills.

While I agree with Jim,  that “the reading tasks online are therefore a significant departure from the traditional, and they require a whole new set of skills,” I think we need to look at the issue from another direction, too. To be most effective as a learning tool, online technology has to evolve to the point that students can readily use the skills they already have in addition to (perhaps, while learning) these new skills. Otherwise, rather than being an educational equalizer, the online environment will be just another way that we sift and sort students. We will lose those who can’t adapt easily, and we will be educating only those who can.

Social Networking: Weaving the Web of Informal Ties

Stefanie PankeBy Stefanie Panke
Editor, Social Software in Education

The term networking describes the behavioral patterns that people display to gain, maintain and make use of social relationships in a professional context. The relevance of the concept has increased in recent years due to its ascribed positive effects on individual career paths. Online social networking aims to strengthen informal ties, even within formal settings. These informal connections may ease the stress and stiffness of work-related tasks. People who are part of the informal social network provide resources or further contacts, and reciprocal advantages emerge among the networkers. Examples include simplifying workflows (“cutting through the red tape”), passing on strategic information and mentoring network members in their professional development.

Whereas networking traditionally takes place during conference breaks, in the office’s kitchenette or at the water dispenser, nowadays more and more business contacts are established online. “Social Networking once meant going to a social function such as a cocktail party, conference, or business luncheon. Today, much social networking is achieved through Web sites such as MySpace, Facebook, or LinkedIn” (Roberts & Roach, 2009, pp. 110-111)

For the majority of students the profile in a social networking community is a natural part of their everyday communication portfolio – just as indispensable as the cell phone or e-mail address.

Since student life is to a great and increasing degree mediated through social networking platforms, academic teachers can hardly ignore these environments.

Platforms such as MySpace and Facebook are likely to attract more student attention than the university’s learning management system. These “social” Web portals form a widely accepted virtual meeting point to deal with the social components of campus life.

This new gathering point challenges academic teachers to find a personal strategy for dealing with social networking sites. Should teachers leave the social networking playground to students or should they actively engage in social networking practices to open up a new communication channel with their students? What platforms are out there to choose from, what appeals to their respective target group and what are the prospects and problems of these Web sites?

Examples

In general, all social networking Web sites are used to organize social contacts online. However, networks differ in their character, which depends on the applications offered, the conventions of use and the kind of relationships displayed in the network. Depending on the character of the site, the member profile page highlights specific aspects of the user’s personality and interests and mediates how he or she interacts with other members. For instance, Facebook, which targets mainly students, features a high amount of informal communication and games, differing in this respect from the platform LinkedIn, which is particularly focused on professional contacts and thus features business recommendations and testimonials. There are numerous social networking sites, which differ greatly in their focus and reach. The following examples are either widely used or specifically target an academic audience:

Facebook: Founded in 2004, the platform has 300 million active users per month. Originally, Facebook was accessible for a limited target group. Until September 2006, users needed the e-mail address of a university to register. Still, students are the dominant member group, though other segments are picking up.

LinkedIn: Since its launch in 2003, the network has attracted 50 million users worldwide. The Web site allows registered users to maintain a contacts list with trusted business acquaintances (so called connections). For student supervisors it is a helpful tool to provide recommendations and support graduates entering the job market.

NING: In this Web community, groups can create and manage their own social network. Ning was launched in October 2005 and has more than 1.6 million members. Examples for e-learning related networks are the AACE Connect community organized by the Association for the Advancement of Computing in Education (AACE) or the Special Interest Group Evaluation of Learners’ Experiences of E-Learning (ELESIG).

MySpace: Since its launch in 2004, the music community and other interest groups continue to heavily use MySpace. Each month 125 million users worldwide log in to their account, search for songs, bands and tour dates, add contacts and post their own photos and videos. Users may continue to access MySpace for political happenings such as the last presidential election or healthcare bill. A rubric dedicated to education and the organization of school events is MySpace School.

ResearchGATE was founded in May 2008. The platform aims to create an international network of scientists and has been quite successful so far. ResearchGATE has 180,000 members worldwide and grows with a rate of approximately 1000 new member registrations daily. The features are targeted to a scientific audience, for instance, supporting the “self archiving” of publications.

scholarz.net has been in existence since 2007 and has approximately 3000 members. The site is a mixture of citation management tool, search engine and meeting point for  scholars. The start-up was originally a research project at the German University of Würzburg. The academic background along with its advertisement free environment adds to the credibility of the site. In the future, their business model foresees member fees.

Prospects

An important part of the university experience is building personal relationship networks. Contacts with fellow students are constantly negotiated, evaluated and maintained collaboratively. Whereas common activities strengthen relationships, inactivity renders them fragile or stagnant at best. Communicating through social networking pages is a means to foster and deepen interpersonal contacts. At this, users are by and large not attracted by the anonymity of the WWW. Despite the potential of global networking, a major amount of contacts maintained through social networks mirrors local binds and relationships to friends, study peers or working colleagues (Livingstone, 2008).

A heavily cited advantage of engaging in social networks goes back to the work and writings of Granovetter (1974). According to the researcher, strong social ties towards friends, neighbors or family members are less relevant for finding a job or choosing a career path than indirect or transient contacts (weak social ties). Social networking platforms make it easier to find indirect connections through visualizing second and third degree contacts. Thereby, one can, with little effort, leverage these contacts and make them a part of one‘s personal network. Plus, the profile page in a social networking site starts to replace the personal homepage. It opens up an easy way to gain experiences in designing Web pages and putting together references and other CV information.

All in all, social networking platforms can be seen as relationship management tools that answer everyday questions of student life. When again is the birthday of my new pal from the introductory course? How can I reach the members of my study group? Short status messages allow for easy navigation in one’s own social network, track activities and keep up to date.  Although students use networks such as Facebook chiefly for informal communication, organizing learning activities is in many cases a sidekick to simply having fun.

Problems

The ubiquitous presence of social networking sites in campus life can develop an unwelcomed dynamic. As a matter of principle, the nature and amount of personal information displayed online should be a personal decision by the individual student. But when all fellow students, the tutors and even the teacher meet on facebook, how can one afford to stay behind? Once a member, the student has to cope with the continuous stream of information. Do I have to react to every short message? Should I also become a member in this new learning network? How many online identities can I manage at a time? The pressure and urge to be ubiquitously present and constantly online can turn out to be detrimental to a student’s learning experience.

The unchecked and uncontrollable aggregation of data and the potential for commercial leverage of member profiles are two central points of criticism when it comes to social networking. Different providers follow specific business models, e.g., collecting fees for special services or unlimited storage, advertising general and personalized products based on information in the members’ profiles.

The close interplay between the social networking profile and the person’s relationship management results in a state of dependence towards the provider. What happens when the provider changes the terms of use? Facebook, for example, introduced in 2006 the feature “Newsfeeds.” Many users protested against this decision that created more transparency and awareness of personal information (Boyd, 2008). In the end users can only choose between the two options of accommodating or leaving the platform altogether.

Likewise, the postings and comments of other users, which are displayed within one’s own profile, result in a loss of personal control. Each online identity needs continuous maintenance to be free of spam and other unwanted pictures, games or comments. This upkeep is particularly important since employers increasingly use the Internet for background checks.

Teaching and Learning Scenarios

  • Coordination: Several academic teachers started using Facebook as a tool for working together with colleagues, tutors, research assistants and students. The short messages and status notifications are ideal for arranging duties and coordinating cooperative tasks. As Sara Dixon from the department of psychology at St. Edward’s University puts it: “It is so fast . . . . They check their facebook profile more often than their email account.” The Creative Writing Network on Facebook is a collection of teaching material shared between academics. As the profile page says: “It’s a place to share book and article titles of craft criticism, announce events related to teaching creative writing, and discuss issues in our field.”
  • Narration: Brown & Donohue (2007) describe the use of social networking portals in literature studies. When discussing fictional characters in the classroom, a character specific MySpace-profile offers the link to a context students are familiar with:  “[…] it can be useful to ask what that character’s MySpace page might look like — what might such a character include in their ‘Interests’ or ‘About Me’ section? The MySpace template offers students a way to talk about identity construction in familiar ways.”

Alumni: The German university RWTH Aachen uses the platform XING as a tool to support alumni. The alumni group was established in October 2004 and now has 9000 members. Another example is the facebook group from Thomas College or the University of California group on MySpace.

  • Lectures: The media informatics work group of Prof. Oliver Vornberger from the German University of Osnabrück has developed a plug-in for Facebook called social virtPresenter. It allows the distribution of lecture recordings via the social networking site. This supports social navigation through the lecture contents.

Conclusions

Whether or not academic teachers choose to create personal social networking profiles and the degree to which they make use of it is a personal decision, one that cannot be made unambiguously from a pedagogical point of view. Mazer et al. (2007) researched the influence of teachers’ Facebook profiles on student motivation, learning behavior and learning climate. In addition, students were allowed to comment on how appropriate they perceived the teachers’ Facebook profiles. Despite positive effects on student motivation in the experimental setting, the majority of subjects surveyed reported that an in-depth teacher profile appears to them as “unprofessional.”

Since student life is to a great and increasing degree mediated through social networking platforms, academic teachers can hardly ignore these environments. Knowledge and personal experience can help instructors to facilitate media competence, critical reflection and responsible use of social networking tools among students. Whenever an openly accessible Web site becomes part of the official learning environment, teachers have a certain responsibility for the way students present themselves and interact with each other online. If open social networks are to be used, it makes sense to develop a respective “netiquette.” Furthermore, teachers need to create awareness of privacy settings.

Social networks with an academic focus, such as ResearchGATE or scholarz, offer the advantage of features that are tailored to the target group of researchers and students. They offer options to manage citations, post presentations and articles, and support educational activities. This makes them a good starting point for teachers to get into social networking.

Online Multimedia: Italian Imperialism

Accessibility 4 All by Claude Almansi

Italian bill on multimedia services

The Italian parliament is presently examining a government proposal of a decree that would modify the law on TV and radio towards the implementation of  “Directive 2007/65/EC [Webcite archived version] of the European Parliament and of the Council of 11 December 2007 amending Council Directive 89/552/EEC on the coordination of certain provisions laid down by law, regulation or administrative action in Member States concerning the pursuit of television broadcasting activities.”

The human-readable “schede di lettura” (reading notes) of the Camera dei deputati (Lower House) are available online [Webcite archived version]. The actual bill in legalese has not been officially published online, but an unofficial scan of a fax version is available from several sites, e.g., mcreporter.info/documenti/ac169.pdf (3.7 MB).

Online video = television

While the EU directive’s purpose is to take into account new on demand television offers, the definition of multimedia services in article 4 of the Italian bill also equates Web sites/platforms that offer online video to multimedia services subject to the same obligations stipulated by the bill as television broadcasters, unless their use of video is merely “incidental.” Among these obligations: editorial control, which means – in the case of web sites/platform offering videos – provider’s liability.

Jurisdiction

Article 2 of the Italian bill stipulates that media service providers – including sites/platforms hosting videos in a “non incidental” way, see above – situated in Italy are subject to Italian jurisdiction, i.e., to the bill. The bill’s definition of “situated in Italy” includes media service providers:

  • whose main seat is in Italy, even if editorial decisions are taken in another State of the EU
  • whose main seat is in Italy, even if service decisions are taken in another State of the EU
  • who use an earth-satellite up-link based in Italy

Moreover, article 3, about cross-border broadcasting, of the Italian bill stipulates that Italy  can ask, at the request of EU members, for the block of broadcasts from non-EU countries for motives of:

  • public order
  • protection of public health
  • safeguard of public safety, including national defense
  • consumers’ and investors’ protection

and impose a fine of Euro 150.00 – 150’000.00 if the non-EU provider does not comply with the blocking demand.

Paradox of timing restrictions for adult (pornographic, violent) content

One of the paradoxes of considering sites/platforms that offer videos as televisions subject to the bill appears in its article 9, about the protection of minors. This article stipulates that adult (pornographic or violent) content cannot be broadcast between 7 am and 11 pm.

As to the absurdity of applying such a timing limitation to videos offered on the web, see Kine’s ironic remark in the discussion Decreto Romani – Stop ai film vietati in TV e sul Web [Webcite archived version] started Jan. 21, 2010: “Come sarebbe anche al WEB scusa? Non [l]i guardo i film su youjizz dalle 7 alle 23?” (“What, also on the WEB? Can’t I watch videos on youjizz from 7 am to 11 pm?”)

Threat to accessibility

The Italian bill creates a similar absurdity for accessibility: it keeps the EU directive’s audiodescription and  captioning requirements for TV, but it threatens the possibility to use Web sites / platforms offering videos by submitting them to the same  conditions as TV channels. And even if a text-only offering of information and knowledge will pass automated accessibility tests, multimedia is a very important part of real accessibility for all.

The paradox here is that Italy has probably the best legal tools for furthering computer accessibility in EU, and maybe in the world, and actually works at implementing them. See the accessibile.gov.it site of the official observatory for accessibility in the public administration, which recently published Roberto Ellero’s tutorial on Accessibilità e qualità dei contenuti audiovisivi [Webcite archived version]  (Accessibility and quality of audiovisual content).

This tutorial fully integrates a text part and a video provided with Italian and English subtitles:

Webmultimediale

In the text part, Roberto Ellero refers to several pages of www.webmultimediale.org, the main site of  Webmultimediale, a project he founded for the study of online multimedia, and in particular of how the accessibility requirements for online multimedia can be a stimulus for creativity and a great help in education because these requirements also cater to various learning styles.

Webmultimediale is among the projects directly threatened by the bill’s equating of online videos with TV offerings. Not only does its www.webmultimediale.org site make a “non incidental” use of video, but it also has an open video hosting part, www.webmultimediale.it, where people upload their videos with a time-coded transcript in order to caption them. No way either could be maintained if the bill passes. Which means that Roberto Ellero’s tutorial on Accessibilità e qualità dei contenuti audiovisivi [Webcite archived version], commissioned by the government’s Observatory of accessibility in the public administration, would be severely maimed.

I happen to participate in the Webmultimediale project. The jurisdiction conditions in the bill made me think of a discussion about Web accessibility Roberto and I animated at the end of last November. Roberto lives in Venice; I, in Geneva. The discussion venue was the Instructional Technology Forum mailing list, based at the University of Georgia (US) but with subscribers from all over the world, and how we all used variously hosted e-mail accounts. So where were “editorial” decisions made, in so far as there were any? Were they made, e.g., when I embedded a California-hosted YouTube video, made by Roberto in Venice, in the Florida-hosted wiki that we used for background material and, later, to gather the discussion threads? Under what jurisdiction did I do that?

Threat to education

Beyond the Webmultimediale example above, it is the use of multimedia in Italian education that is put at risk by the bill. If it becomes law, what teachers and educational institutions will dare offer a video podcast of lectures, scientific experiments, and use of video in teaching under the threat of being asked to comply with the administrative requirements imposed by the bill for TV broadcasters? Even if they try to upload the videos on a foreign platform and link to them, there would still be a risk that the foreign platform will be considered a television broadcaster and blocked in Italy.

Reading Ability As a ‘New’ Challenge for Online Students

Totally Online, by Jim Shimabukuro

Mary Alexander, Wayne Clugston, and Elizabeth Tice’s The R-Model for Learning Online and Achieving Lifelong Goals (San Diego: Bridgepoint Education, Inc., 2009) is a self-help guide to assessing readiness for online learning. Ashford News published a review (“Top Tips for Online Learning” 1.25.10) this past week, including a summary of attitudes and abilities required for success in the online classroom.

One of the key suggestions is “restructuring,” or rearranging “your life so that you have time to devote to your studies. Online learning removes the travel, parking and childcare issues related to driving to a brick-and-mortar campus, but there is no getting around the fact that you will have to carve out time to read, write, think and interact with instructors and peers.”

The list also includes a reminder to sharpen writing skills since, “as an online student, writing is your sole means of actively participating, building relationships and demonstrating active learning in an online environment.”

a girl using a laptop outside, in a beautiful hilly landscape, with the words: The R-Model for Learning Online and Achieving Lifelong Goals - Ashford UniversityThe review, however, does not include an item on reading readiness, or the problem of students unprepared for reading online (SUROs). I haven’t had a chance to review the book so I’m not sure if, in fact, this topic is covered. In any case, as an online instructor, I think the lack of effective reading skills is perhaps the biggest obstacle to success.

The crossover from F2F (face to face or real-time) to virtual classrooms is so widespread today that we tend to forget that these are actually very different environments. And one of the key differences is the role that reading plays in web-based classes. In F2F classes, reading is primarily associated with content in textbooks and articles. Procedural instructions are delivered orally and discussed, and printed handouts are used as reminders. In online classes, however, both procedural guidelines and content are accessible only through reading. The reading tasks online are therefore a significant departure from the traditional, and they require a whole new set of skills.

Despite all the advances in web technology, information on a computer screen is still presented one screen at a time.

This isolation of information in a two-dimensional frame creates a critical demand: students must be able to impose a time and space dimension on the information in the otherwise flat screen. Effective readers are able to take individual frames and use them to construct a dynamic, three-dimensional, real-time model. They’re able, in other words, to build a whole from disparate parts — a whole that also incorporates an accurate representation of the entire online learning experience from the first to last day of instruction as well as their own location, at any given time, within the model.

Effective readers are aware that each piece of information is an important part of a larger puzzle that’s continually evolving and that ignoring or forgetting a piece could be disastrous.

The critical difference between F2F and online classes is the sense of now, or knowing where one is in terms of time and space. F2F, students are always in the present, and the future is a linear path that extends from now into tomorrow, next week, etc. They know exactly where they are in the present, e.g., in their classroom, at their desk, on page two of the handout, with the instructor at the chalkboard and classmates seated around them.

Online, however, students don’t have the same sense of now because past, present, and future are equally accessible. They also don’t have the same sense of where they are in terms of classmates and activities since they can’t see others and what they’re doing.

F2F, students who are unwilling or unable to construct an accurate model can still manage to survive and even thrive by simply showing up for class and depending on others in their shared environment for cues. If others are noting a point made by the instructor, then it must be important. The instructor reminds them to turn to page three, now; toward the end of class, he reminds them to submit their drafts in the next session.

Online, these cues are missing from the screen the students are on at the moment.

Red flags for SUROs usually pop up in the first few days of instruction. Perhaps the most common for those who can’t or won’t accept the generative or active function of reading is the following post in discussions or email: “Help. I’ve read everything but don’t have a clue about what to do for this class. Can you (or someone) tell me what I’m supposed to do next?”

The instructor has clearly announced the importance of reviewing the schedule of activities daily, and the assignment that’s due “next” is boldly spelled out in the schedule, but this information is not directly in front of the student at the moment and, thus, doesn’t exist. The student has failed to add this information or, more importantly, the sources of this information to his/her mental construct of the class. In fact, the student’s image of the class is limited to the screen that happens to be in front of him and the other information is lumped into an amorphous mass.

The point is that reality is concrete, abstract, and dynamic, and students who can’t synthesize all three into a working model will have difficulty in an online class.

Another red flag is a student’s insistence on regular F2F or real-time contact with the instructor. These students need to establish and maintain a sense of here and now to get their bearings. They can’t function without the cues that are present in F2F environments. Once the instructor agrees to these real-time interactions, he/she falls into a semester-long trap and literally ends up tutoring the student in a traditional classroom, effectively teaching two classes instead of one, and this places a labor-intensive burden on the instructor.

Students who must have continuous F2F or real-time contact with the instructor simply aren’t ready for online learning.

A third red flag is the consistent failure to follow directions or guidelines. Reminders to do so are usually met with hostility, with the student insisting that he has read the guidelines many times over. For these students, out of sight is out of mind, literally. They’ve read the requirements, but once they’ve moved on to the next screen, the guidelines cease to exist in a form that could inform the current activity.

There are other red flags, I’m sure, but these should suffice for the argument that the reading challenge for online learning is considerable. I’m not sure exactly how to prepare or assist SUROs. I am certain, though, that providing real-time safety nets for them compounds rather than resolves the problem. I’m also certain that, in this day and age, the ability to learn — to reconstruct bits and pieces of virtual information into a real-time working model — online is essential.

Berkeley High School May Eliminate Science Labs

Retort by Harry Keller with a distilling retort on the left
Just put the title of this article into your favorite search engine. The Berkeley High Governance Council (BHGC) has just voted to stop providing science labs to its students so that the roughly $400,000 cost can be redirected into programs to support struggling students.

Berkeley High School (BHS) has a number of features that most schools do not. It’s located in a community that includes lots of University professors and dot-com entrepreneurs and employees as well as plenty of African-American and Latino households.

BHS gives its science labs before and after normal school hours. Five teachers supervise these lab sessions. The reason for the unusual laboratory time scheduling appears to be overcrowding because lab space has been taken during normal school hours for non-lab instructional activities.

Blogs seem to be going wild over this proposed change with charges of racisim flying around like dust on a windy day. The achievement gap at BHS is well beyond national norms. These labs are being labeled as “white” courses. However, one AP teacher claims that her four AP Environmental Science course contain one-third minority students. No figures have been given for AP Physics, AP Biology, or AP Chemistry. The College Board does not label AP Environmental Science as a “laboratory science” course.

Detail of the school building, with the words Berkeley HighWhat’s to be done? Is the threat to close down the science labs just a threat, a ploy to get more money for remedial education? Does the BGHC really believe that science labs should go? The science department certainly does not. “The majority of the science department believes that this major policy decision affecting the entire student body, the faculty, and the community has been made without any notification, without a hearing,” according to Mardi Sicular-Mertens, the senior member of Berkeley High School’s science department.

This news brings a number of issues together at once and makes sorting them out difficult. It also brings focus on some important issues in education.

Regarding the achievement gap, BHS has an unusually large number of high-achieving students, a fact that skews the achievement gap. Low-achieving students at BHS may do better than in the average California school, although one report puts them below the national average. While that statistic does not remove the necessity for helping low-achieving students, it does make the BHGC action seem rather precipitate.

The necessity for holding special lab sessions in which students typically perform 19th-century experiments in 19th-century ways may be crumbling in the 21st century. We all should be asking ourselves what future we’re preparing students for in these lab sessions. Realize that most science laboratory experiences are “poor” according to the National Research Council. Pipetting technique hardly qualifies as a necessity in today’s job market.

Schools have the means to provide valid lab experiences today that weren’t available before. Instead of removing labs for many students, they should be providing them for all students. Provide appropriate challenges to every student, and make those challenges real, not make-work. This issue goes far beyond science instruction. We face the problem that science just happens to cost more than other academic subjects. History, for example, escapes this dilemma because history courses don’t have labs. In fact, of all non-science school activities, only sports seems to have high-cost settings and major equipment costs.

Schools have the means to provide valid lab experiences today that weren’t available before. Instead of removing labs for many students, they should be providing them for all students.

All educators must rethink our educational system. We must face the fact that a large fraction of students entering school each year are unprepared to learn at the pace required. Finding ways to challenge every student to reach an optimal level of learning must be our goal. Some will begin behind, but many can catch up if challenged appropriately.

Science labs may be just a small piece of this puzzle, but they’re an important one. In these labs, if done properly, students will learn scientific thinking, an important tool for everyday life. They’ll come to understand the nature of science and so be better prepared to make important decisions involving science and technology, stuff that can be as mundane as selecting a laundry detergent. And they’ll have experience with empirical data, an experience that models the complex and ambiguous nature of life in our society today.

When taught well, science (and history too) can challenge students to improve reading and writing abilities as well as critical thinking. Science also helps with math skills. Investigating their world brings engagement to students. Engagement can, in the hands of good teachers, lead to motivation to learn communication skills and math. Thus, the science (and history) courses become the remediation courses for all but the most challenged of students.

Our current recession and global competition combined with the ferment of online education and charter schools have placed large burdens on our society. Technology, as usual, may be our downfall or our savior. We have no perfect solution. Let’s hope that BHS and others make informed and successful compromises that will ensure our future remains bright.

Immediacy and Presence in Online Learning

Totally Online, by Jim ShimabukuroCredence Baker‘s study, “The Impact of Instructor Immediacy and Presence for Online Student Affective Learning, Cognition, and Motivation” in The Journal of Educators Online (7.1, January 2010), is a substantial contribution to online instructional pedagogy.

The study focuses on instructor presence and immediacy in online courses. Presence is manifested in “instructional design and organization, facilitating discourse, and direct instruction”; verbal immediacy, in behaviors such as “giving praise, using humor, using self-disclosure.”

Major findings:

  • “While instructor immediacy was shown to be positively related to student affective learning, cognition, and motivation, it was not shown to be a significant predictor.”
  • “Instructor presence . . . is a significant predictor of student affective learning, cognition, and motivation.”

Instructional activities that impact presence “include presenting content and questions, focusing the discussion on specific issues, summarizing discussion, confirming understanding, diagnosing misperceptions, injecting knowledge from diverse sources and responding to student’s technical concerns.”

According to Baker, a “limitation of the study is the self-reporting nature of the measurement instrument [online survey], which hinders the ability to control errors and bias in the participants’ responses.”

Breakdown of the subjects: “The data collected for this study included 377 (n=377) uniquely completed surveys submitted online. Of the 377 respondents, 265 were females and 112 were males. A total of 71 students (18.8 %) indicated that this was their first online course, and 306 students (81.2%) indicated that they had had previous online course experiences. One hundred forty-one (141) respondents (37.5%) reported being graduate students, whereas 236 respondents (62.5%) reported being undergraduate students.”

Comments

One of my concerns centers on the discreteness of the predictor variables, presence and immediacy, which tend to overlap in discussion activities. For example, instructor participation in online class forums, the most direct means of interaction, seems to incorporate both variables, complicating comparisons.

This concern, however, takes nothing away from the confirmation that course design (to establish presence) is critical for an online class, and, arguably, the most critical implication of this finding is the need to provide ongoing released time for online faculty to continually develop, maintain, and update their virtual learning environments.

Perhaps a second important implication to improve presence (and immediacy) is to explore the incorporation of discussion moderators for online forums. This role could be filled by selected students trained to facilitate discussions.

A third implication is probably controversial, but it needs to be examined — recruiting and hiring instructors who are skilled in developing and using online learning environments. Currently, most online instructors use course management systems (CMSs) maintained by information technology (IT) staff. Eventually, through in-service workshops, they become adept at getting the most out of the CMS. To strengthen online offerings, colleges may want to include CMS skill as a prerequisite for employment.

A fourth implication is that colleges may want to provide ongoing released time for the development of skills that take the instructor beyond the confines of CMSs as well as funds and IT support to implement innovations outside the boundaries of CMSs. Since course design is so critical, it may be time to open it up to influences and resources beyond the college’s IT department.

A fifth and final implication is the need for colleges to keep a finger on the pulse of current technology actually used by our students, who are increasingly turning to handheld communication devices that bridge the gap between cell phone and notebook computer. For many or most of our students, the boundary between face-to-face (F2F) and virtual is shrinking so rapidly that they no longer make a distinction between the two. For all practical purposes, they are one and the same. We may, in other words, have reached the point where the online vs. F2F controversy is, literally, academic.

Baker’s study comes at an opportune time, interrupting a relatively dead period in the dialogue on online instruction. This may be just the breakthrough needed to explore the next step in online education.

Deconstructing STEM

Retort by Harry Keller with a distilling retort on the left

In K-12 education these days, you’ll see frequent use of the acronym, STEM. This word stands for “science, technology, engineering, and mathematics.” This term is so widespread that no one even seems to question its use. Yet, the inclusion of these four subjects and the exclusion of any other is actually rather arbitrary and tends to mislead the general public about the nature of these subjects and how to teach them. Possibly, it’s the push from industry for more employees trained in these areas that has resulted in this emphasis.

Many people, even in education, do not have a full understanding of the essential differences between these four subjects. Science teachers may present them to students as being essentially the same. Funding agencies are proposing lots of money for STEM education. What are they proposing to fund? Even if you know all about STEM, please take a moment to read the analysis below and comment on anything that’s incorrect or incomplete.

To begin with, why exclude other subjects? For example, physical education uses science, technology, engineering, and mathematics extensively. If the use of one subject by another is reason enough for inclusion in a grouping, then physical education certainly should be added to form something like STEPEM. You can make a case for inclusion of some other subjects as well. Roping off four subjects from everything else makes no real sense for education.

However, it’s the lumping together of these four that makes the least sense. Why not HELASSAWL, grouping history, English language arts, social science, arts, and world languages? Yeah, it’s a mouthful compared to STEM, but logically, it makes as much sense. To understand why, take a look at each of the four STEM subjects.

Mathematics began centuries ago as a means to an end. It was used to regulate trade (arithmetic) and to deal with land (geometry). Then, Euclid came along and made logical, step-by-step proofs the bedrock of geometry. Mathematics hasn’t been the same since. Instead of being just a means to an end, mathematics now stands by itself in pure abstraction with its proof-based system of functioning.

Something that hasn’t been proved in mathematics is merely a conjecture. Mathematicians don’t have to relate their work to anything going on in science, technology, or engineering. They start with axioms and build a tower of theorems, corollaries, and lemmas. Doing mathematics requires a special way of thinking and extensive training.

In total contrast to mathematics, science is all about disproof. Science doesn’t stand apart from the real world in abstractions. Science involves inquiry, exploration, and discovery within the context of reality. It’s a voyage into the world of ideas that develop into explanations of the universe. Scientific theories mean nothing unless they can be compared with real data.

Scientists know that they can never prove their theories. That’s one reason that they’re called theories. New data tomorrow could overturn or at least modify today’s favorite theory. Examples abound. The geocentric view of the universe was overturned (probably more than once) by the heliocentric theory, which itself was modified when all stars were found to be rotating around a galactic center.

Mathematics plays an important role in every branch of science. The eponymous Lord Kelvin, immortalized as a temperature scale, said, “When you measure what you are speaking about and express it in numbers, you know something about it.” Mathematics then allows processing of those numbers. Whether physicists are doing quantum mechanics or biologists are making statistical analyses of experimental results, mathematics permeates science. Nevertheless, mathematics is not science. Doing science requires a special, nonintuitive way of thinking and extensive training.

Engineering is all about making things. Engineers use the knowledge they have of how things work to create new physical entities. Much of this knowledge comes from other engineers who have tried numerous approaches and found which work best, and the data used are empirical. Other knowledge comes from the discoveries of scientists.

Engineers design, build, and test. They create skyscrapers and highways, toasters and microwave ovens, automobiles and racing bicycles. Scientists discover; engineers create. These two acts, discovery and creation, seem to be wired into our brains so that we consider them to be very pleasurable. There’s little other connection between these two disciplines, except that they seem to require each other. The discoveries of science help to fuel new engineering, and the new stuff that engineers create often provides devices that scientists use in their research such as telescopes, microscopes, spectrophotometers, and so on. Engineers require extensive training.

Technology is the stuff that mankind creates. It comes originally from engineers and inventors.

Technology is the stuff that mankind creates. It comes originally from engineers and inventors. Building a fire and crafting a spear were early examples of using technology. Today, it’s hard to take a step without involving technology, for example, the technology represented by your shoes. Because technologies are closely tied with scientific discoveries and with engineering designs and creations, people may readily confuse these.

A course on technology, by itself, will be a rare occurrence in elementary and secondary schools. Instead, you find technology woven into K-12 science courses along with engineering (e.g., robotics). Technology makes our lives easier, delivers better health, and allows us to explore places previously inaccessible. It also complicates our lives, pollutes our environment in numerous ways, and requires us to extract our planet’s resources to feed it.

Scientists discovered the ideas that made today’s flat panel televisions possible. Engineers turned these ideas along with engineering principles into televisions. The technology consists of the televisions, all of their pieces and parts, and the means to capture and send the images and sound to the individual televisions. In all of these activities, the scientists and engineers use lots of mathematics, but mathematicians play no role in creating televisions. A technologically literate person will know much about the technologies involved in delivering the television experience to living rooms but may not be familiar with the engineering principles involved in the design. This same person may not understand the nature of science either.

Interestingly, the California Institute of Technology provides bachelor’s degrees in mathematics, many branches of science, and several disciplines of engineering. However, there’s no degree in technology.

This conflation of four terms into STEM, an artificial thing that we’re supposed to be excited about teaching to K-12 students, makes little sense. Science and mathematics departments like it because it elevates them somewhat in the din of the discussion of how to improve education. Here’s what’s actually happening on the ground in many school districts. The districts receive some federal money for improving education. The various departments put in their proposals for a piece of this funding. ELA (English language arts) and mathematics ask for more, in total, than is available and receive all of the money. The science and history departments, not to mention music, arts, physical education, and others, get nothing.

The push for improved reading and mathematics scores trumps everything else and shortchanges the places where real learning takes place. But that’s material for another column.
