Teaching Science Teachers Science

All teachers must learn certain things. For example, they learn about learning theory, classroom discipline, and how to write lesson plans. In addition, they learn the material and ideas of their chosen subject area. As I read articles about science education and communicate with many science teachers, I become more convinced that our teachers colleges are not providing the necessary learning to our future science teachers.

What is this necessary learning and why is it important?

To answer this question, you must first understand what science is. Science is not a bunch of “facts,” e.g., Mercury is closest to the Sun; prophase is the first phase of mitosis; force is proportional to the rate of change of momentum; igneous rocks are formed from molten rock. Science is an approach to finding out these things, a way of thinking, of solving problems. It uses the work of previous scientists and new data to be sure. So those “facts” are part of the learning but hardly the most important part.

So-called science facts are always subject to revision, but the means by which they were extracted from nature with great difficulty remains the same. We must teach some science content in order to have material upon which to apply the developing thinking skills of our students.

Science courses inflict lots of vocabulary on students too. Some words seem familiar but are used by scientists in a very specific manner. “Work,” for example, does not take place when you’re holding a heavy weight above your head – if you’re talking about science. Work is a specific and quantitative term in science. Other words seem entirely unfamiliar and even bizarre. In physical science, “entropy” is a made-up word for a measure of disorder in things.

Science education must provide the content of science including vocabulary, an understanding of the nature of science, and development of scientific thinking skills. Anything else is superfluous in primary and secondary education. In post-secondary education of science and medical majors, there’s more, but that part is not the subject of this discussion.

Without an understanding of the nature of science, students will not be able to interpret what’s going on around them every day. You read about global warming and conflicting claims regarding it. You read about protecting species from extinction and then about how 95% of all species in the history of the Earth have gone extinct naturally. You read about an energy crisis and then about how the price of gasoline is being manipulated by Wall Street traders and that the energy situation is just fine. All of this would be just entertainment were it not for the fact that so many countries are democracies, and the people are expected to vote, to make decisions, on these issues in elections.

UC Berkeley’s Online Education Strategy: A Model for Change

Jim ShimabukuroBy Jim Shimabukuro
Editor

In response to the explosive trend in higher ed toward open online courses (OOCs), Berkeley’s executive committee for online education published* the university’s plan for change. As a strategy, it’s an echo of similar guidelines across the country and the world. However, what distinguishes it from all the rest is intelligence. It’s obvious that the committee has done its homework and understands the deeper implications of online education.

The plan has two standout elements. The first is a flexible approach to defining “online” education:

  1. certificate and graduate degree programs that are in high demand
  2. undergraduate gateway and hybrid courses that increase available capacity and enrich learning for our on-campus students
  3. “public good” courses that we will typically offer for free to a wide audience as a community service and as a proven approach to exposing potential students to outstanding Berkeley faculty
  4. development and sale of online educational content that can be deployed by other institutions or organizations

Of these, the fourth is the breakaway, and it implies a deeper understanding of how the current flood of open online courses and platforms might play out. That is, in the coming weeks and months, the key to OOCs may be the way client institutions integrate the courses into their programs. In the end, the value of courses may be in their unbundled state rather than in their current bundled, all-in-one platforms. For example, as unbundled content, OOCs could serve course designers from institutions around the world who would pick and choose parts from different courses — from the same or different colleges — to construct unique course mashups for their students.

This mashing process is familiar to educators who have been doing it with textbooks and multimedia for years. The big difference is that they now have anytime-anywhere access to content provided by some of the top teachers in the world. Furthermore, that content is open (not the same as free) or mashable as well as recorded and available in various digital media. This content could be sold in creative packages to institutions everywhere. This OOC-based business model may be the virtual extension of publishing in the 21st century.

The second element is a vision of integration that implies, once more, a clear awareness of the process of change. Unlike the vast majority of colleges, Berkeley understands that the current practice of “bolting” online programs to traditional onground platforms is a transitional phase. The ultimate shape of viable programs is a work in progress, and no one knows for sure exactly what it will be. The one certainty, however, is that “online methods will ultimately transform our traditional teaching program and we need to begin to systematically align our administrative and support functions to meet the changing needs of online and traditional programs.”

“Systematically align” is a euphemism for change, and when applied to staff and leaders, it means to educate or to keep on top of current trends and developments from as broad and as deep a perspective as possible. In short, this isn’t a time for panic and bandwagon decisions, and this is definitely not a time to sit still, pout, or cling to tradition. At Berkeley, the leaders realize that the future is their responsibility and that it can’t be passed off to others, outside experts or entrepreneurs, or borrowed from other institutions. And a critical part of that responsibility is to think — inside and outside the box.

Pre-online models for education are no longer adequate, yet that is all we have for now. The challenge is to draw a clear distinction between the old masquerading as the new and the genuinely new, between the new as a “bolt on” to the old and the new as an entirely different model that fulfills the promise of online technology. Leadership is critical in times of tumultuous change, and at Berkeley, the leaders have stepped up.

NAEP and the Future of Science Education

picture of Harry KellerBy Harry Keller
Editor, Science Education

Recently, Nora Fleming, in “NAEP Reveals Shallow Grasp of Science” (Education Week, 19 June 2012) reported on a new study regarding the 2009 NAEP (National Assessment of Educational Progress) exam for grades four, eight, and twelve. Around 2,000 students at each grade level were given three “Interactive Computer Tasks” (ICT) and one “Hands-On Task” (HOT) to perform. They were asked questions about each task.

We all know that conclusions such as “shallow grasp of science” are fraught with difficulties, especially when the results tell more about the test than the students. In this case, there are more issues. What exactly does “shallow grasp” mean in this situation? What sort of understanding is required to achieve a high result?

You can check for yourself at a website that allows you to take these tests yourself and score your answers, if you have patience with the tests. I went through the grade 8 and grade 12 materials (my work with science education focuses on grades 6-13) and did not approve of most of the content. Because it’s quite difficult to separate student ability from test quality, the results are suspect.

Because generalities won’t suffice, I’ll provide one example that shows how test results can mislead regarding understanding. This example shows how an eighth-grade student responds to the ICT, “Playground Soil.” According to the instructions,

In this 20-minute task, students investigate the permeability of soil samples from two sites a town is considering for a play area. Students use their results to help decide which site has the better water drainage and is therefore the better place for a grassy play area.

Students analyze two samples: soil sample A that is 10% clay, 50% fine gravel, and 40% silt; and soil sample B that is 10% clay, 50% sand, and 40% silt. Note that the only difference is the middle component. Diagrams illustrate the soil composition.

Students are asked to predict which soil will be more permeable. Generally speaking, the one with more voids (more space between soil grains) will be more permeable. Clearly, fine gravel has larger particles than sand. Now, do a thought experiment with me. Suppose that you increase the size of the fine gravel particles substantially. You might even have a rock in the midst of a clay-silt mixture. The permeability of this rock plus clay-silt will closely match that of clay-silt alone. Now, imagine reducing the size of the rock while keeping the volume equal to one-half of the total. Once the particle size reaches that of clay (60% clay, 40% silt), you’ll have very little permeability because mixtures that are mostly clay don’t allow much water to pass through them.

Udacity and Implications for Higher Ed

Lynn ZimmermannBy Lynn Zimmerman
Editor, Teacher Education

On May 7, 2012, Dick Gordon aired an interview with Sebastian Thrun and David Evans called Udacity: Teaching Online, an online university that came about almost by chance. Although The Story does not air on my NPR station, thanks to modern technology, namely the iPod and podcasts, I was able to download this story and listen to it two months later.

Thrun is Google’s vice president and is recognized as a pioneer in artificial intelligence and robotics. He was a tenured professor at Stanford when his story began. Fall 2011, Thrun decided to make his graduate level AI course, normally taught in a lecture hall to about 200 students, available online for free. He wanted to try to reach a larger audience. He sent out one email announcement. Much to his surprise 160,000 students from all over the world enrolled, and 23,000 completed the course. Thrun was gratified that his experiment was so successful, that free quality education could reach anyone who wanted it.

Sebastian Thrun

During the semester, Thrun had to mend some fences with the administration at Stanford. He had made this decision on his own, and they were concerned about having the Stanford name on certificates he had promised completers. They finally compromised that completers would receive a “statement of accomplishment” from Thrun, a private individual but affiliated with Stanford. So began Udacity, which offers STEM (Science, Technology, Engineering, Mathematics) courses that students can take for free. For a fee they can take tests that certify their knowledge. Although there have been bumps along the way, Thrun says that he cannot imagine teaching any other way. William Bennet, in an interview with Thrun for CNN, “asked Thrun whether his enterprise and others like it will be the end of higher education as we know it — exclusive enclaves for a limited number of students at high tuitions? ‘I think it’s the beginning of higher education,’ Thrun replied. ‘It’s the beginning of higher education for everybody.'” Continue reading

Are Educators So Full of It That They Can No Longer Detect It?

Jim ShimabukuroBy Jim Shimabukuro

Kris W. Kimel[1] says that “higher education, once open to a select portion of the citizenry, is now increasingly available to virtually everyone, anyplace at any time and oftentimes for free.” He also says that “the rise of the innovation and information economy is also sweeping aside the traditional role and position of gatekeepers, those institutions and people who have historically controlled access to the economic playing field, professions and customers.” These are the types of observations that we’d expect from the “president and a founder of the Kentucky Science and Technology Corporation, a non-profit company with an international reputation for designing and implementing innovative and broad-scale initiatives and programs.”[2] A gem, eloquent and accurate.

But hidden under this gem, barely noticeable, is a small stone so rare that it takes your breath away. It’s a comment by someone who goes by the username Seabees1. S/he says that “a larger question relates to academic resistance exercised by countless so-called educators and education planners.” He asks:

Why so much duplication in majors [courses?] among institutions, which siphons off excellence while also wasting taxpayer dollars? Why continue old-fashioned methods of foreign language instruction when new — yes, through technology — techniques trump the status quo?

Why constant boredom in classrooms thanks to professors offering limited lifetime working experience regarding the subjects they allegedly teach?

“Perhaps,” he says, “the culprit is a combination of petty politics, internal self-preservation couched in collegiate mumbo jumbo, and declining teacher preparation by the very organizations offering education degrees. ‘Physician, heal thyself’ doesn’t apply only to medicine.”

It seems Seabees1 has the kind of crap detector that is sorely missing among the vast majority of educators and so-called experts. When those with the power to impact education rely on “collegiate mumbo jumbo” and ignore the signs of their own failure, then the outlook for change is gloomy. Continue reading

Diversity Is Too Important to Ignore in the Talk to Technologize

By Bonnie Bracey Sutton

Two Americas? Are we marginalizing people of diversity by not including them in the conversations? Research? Advisory Boards? Are we the New Invisible Man? I don’t know what it was like during slavery. I do know what it was like during the days of segregation that were a big part of my life. We were an invisible part of the society. We had to follow all the rules, but we were like Ralph Ellison’s Invisible Man.

Now I think there is integration, but I think people in the U.S. live in two worlds, and if the world that they live in is good, they don’t include those from the other world who need to be a part of the ongoing conversation to make the whole continue to work. Most of the reports that we receive in journals and at conferences are well written and researched. However, very little involves those people who are not connected, whose schools are not the best, and whose teachers are not a part of the conversations. I am not talking about the media mavens with one minute pronouncements that dot our television stations. I am talking about the thought changers and the people who guide new ways of thinking, learning, politics, and all. A sustained exposure of diversity issues is critical because technology takes a longer time to dribble down than those twenty year old books that used to come to my community.

I am a member of ISTE. This year’s conference was great, like a moving train. I know how to negotiate it, network. I try to select the ideas that I am interested in and to see the rock stars of education. I notice that there are not that many people of diversity in the mix. A token or two. I watch the crowds to see who of broadening engagement is a part of our groups. Not many. I think ISTE is not making it happen because many people cannot afford the costs of the conference, membership, and travel.

ISTE is no longer a teacher organization per se. It has changed. You can get updated on the latest technology, see this year’s trends, and meet and greet people. One highlight for me this year was to see that Elliot Soloway and Chris Dede‘s ideas of mobile technology have taken off. And then I thought of this article from MindShift. No one was talking about the lack of broadband or permissions to use technology in the schools or the way to negotiate that move. Digital equity seems to have died a quiet death. We did have an SIGDE workshop in the conference. Maybe it is our fault  we have no sponsors. I suppose that lets us know that we are not a real part of the mix. Or does it mean something else?

Year-Round Schooling for the 21st Century: We Can’t Afford to Waste Summers

Frank B. WithrowBy Frank B. Withrow

At this time of year I always wonder at our slavish adherence to an agrarian schedule for schools. Million dollar plants are closed for the summer. Well, not completely. We often have the athletic departments active with team sports.

Staff, from teachers to principals, find summer jobs. I once had a principal who had a summer company to paint houses. He hired his male teachers, and they had a good business. Some of his teachers made more on their summer jobs than they did teaching.

We know that students lose much of what they have learned during this down time and that much of the first two months of the fall semester is spent relearning what they have lost.

If Walmart and others can serve their customers 24 hours a day year round, why do schools continue to tie themselves into a rigid and ill-conceived obsolete schedule?

What if we had a year-round, open schedule school system designed for modern families? For example, the schedule follows the family’s schedule. The students are in school from 8 to 5 each day or from 10 to 6 or even assigned as it fits their individual learning plan (ILP). The school is open from 7 in the morning to 7 in the evening. Students are assigned based upon their ILPs. Teaching staff schedules are also flexible in order to cover the entire day.

In this projected school system, there are traditional classes as well as virtual learning at home and at school through social media. All year long students engage in special learning experiences built around project based learning where learners, working in teams, experiment with such things as actually constructing a robot to serve disabled individuals.
