Jason Ohler, who wrote “Whither Writing Instruction in the 21st Century?” for ETC five years ago, released a new book last month, 4Four Big Ideas for the Future: Understanding Our Innovative Selves.

Jason developed a disease called idiopathic pulmonary fibrosis from which he never expected to recover. It slowly and literally took his breath away. At the 11th hour, he received a double lung transplant.

“Rather miraculous,” he says. “A year later I have a new site, newsletter and book and feel great, back working full tilt, as inspired as ever.”

When he was huddled around an oxygen machine 24/7, he thought a lot. This book reflects what is important to him about life, learning and technology. Read some of the reviews for his book.

From the Amazon ad: “Dr. Jason Ohler has been telling stories about the future that are rooted in the realities of the past during the entire thirty five years he has been involved in the world of high technology and innovative education. He is a professor emeritus, distinguished president’s professor of educational technology and virtual learning who has won numerous awards for his work. He is author of many books, articles and online resources, and is a speaker, humorist, teacher, media psychologist, cyber researcher and grandpa. He is also a lifelong digital humanist who is well known for the passion, insight and humor that he brings to his presentations, projects and publications.”

Creating Community in an Online Classroom: Part 1 – Getting to Know You

Posted on February 9, 2016 by JimS

Judith_McDaniel2_80By Judith McDaniel with Tim Fraser-Bumatay, Daniel Herrera, and Ryan Kelly1

Is it possible to get a “real education” from an online class? Several years ago a professor from the University of Virginia published an opinion piece about online education in the New York Times and insisted that it was impossible. “You can get knowledge,” he continued, “from an Internet course if you’re highly motivated to learn. But in real courses the students and teachers come together and create an immediate and vital community of learning.”2

I teach literature in a fully online Master’s program. My students enroll from all over the United States and from overseas. Our asynchronous discussion forums give students an opportunity to interact, to be thoughtful in their responses to my discussion prompts and to one another. I find the online classroom to be stimulating, diverse, and creative. It is different from a face-to-face class experience, but it can be different in ways that enhance student learning through the creation of an online community.

I am joined in writing this article by three of the students who have just completed their Masters degree in Literature and Writing in this online program. We have created an article that has two parts. In the first we talk about building community and how that happens, how students from very different backgrounds begin to interact, enjoy one another, challenge one another. In the second part of the article, we recreate some of the conversations we had about difficult subjects and difficult texts. We talked about race extensively when we read Othello and Heart of Darkness.  Continue reading →

Zen and the Art of Instructional Technology

Posted on August 13, 2015 by JimS

Jim ShimabukuroBy Jim Shimabukuro
Editor

Updated 8/14/15

In her latest article, Lynn Zimmerman comments on Dian Schaffhauser’s “5 Essential Multimedia Skills Every Educator Must Master.” The skill that grabbed my attention is “Troubleshooting Your Own Tech.”

Troubleshooting is the most critical tech skill for 21st century teachers. Integrating tech into instruction invites “Trouble,” with a capital “T” no less. But it’s “good” trouble, the kind that extends our students’ reach into the world of web-based information and communications.

Technology is the proverbial can of worms, problems that mount as usage increases and deepens. Again, these are “good” problems, problems that come with the new territory that technology has opened up.

There’s no escaping the need to troubleshoot, or problem-solve. Teachers have to embrace the messiness that technology represents. They have to be willing to get their hands dirty, to pop the hood of hardware and software to see what the problem is, to futz with the parts to fix it, often with students looking over their shoulder and getting their hands dirty, too.

I’m not talking about repairing hardware or debugging software, although these are possibilities down the road. I’m talking about basic user-oriented skills such as setting up LMS and social media (SM) accounts, designing and developing course websites and resources, navigating the virtual learning environment, posting and commenting, participating in and moderating online forums, customizing settings, maintaining links, developing and maintaining static and interactive course webpages, integrating apps and SM such as Twitter and blogs into the teaching and learning process; intermediate skills such as coding in basic HTML to provide additional functions in apps, developing graphics and videos to facilitate learning, troubleshooting hardware and software usage and compatibility issues; and advanced skills such as continuously adapting hard and soft as well as traditional and new technology in innovative ways to enhance instruction and learning.

It’s important to stress that troubleshooting isn’t an exception, a one-time thing. It’s the norm in the world of instructional tech. It is an integral part of the process, which is continuous, dynamic, organic. When — not if — teachers run into problems, they should be able to fix them on their own. This ability to troubleshoot independently is critical because it gives them the skills they need to help their students, who will raise not only similar but a wider range of problems at a frequency that increases exponentially with class size. Referring most or all of these problems to IT specialists is simply out of the question. Instruction would never get off the starting line block.

It’s also important to note that technology is a “we” thing in the online or blended classroom, which means troubleshooting is a communal process. Everyone is at once a learner and a teacher, and the roles shift from moment to moment, from tech to tech. Thus, the ability to work collaboratively with colleagues, support staff, students, and others is essential.

A teacher who can’t or won’t troubleshoot will never be able to use tech in instruction. Total reliance on IT specialists to solve every tech problem is simply unsustainable.

But the good news is that once a teacher experiences the high that comes with getting under the hood and attacking a problem, s/he is on the road to becoming a DYOT (Do Your Own Tech) junkie. For a DYOTer, a problem is an invitation to learn, and with every mastery comes increased confidence and daring in trying out other technology.

Why Teaching Is No Longer Relevant in Online Courses and MOOCs

Posted on July 7, 2015 by JimS

Jim ShimabukuroBy Jim Shimabukuro
Editor

Harry Keller raises some hot issues in his comment on “Attrition in MOOCs: Is It a Problem or an Advantage?” The good news is that most are attributable to course design, which exposes a critical difference between traditional and blended courses, on the one hand, and online courses and MOOCs, on the other. In contrast to a series of teacher-led onground classes, an online course is more like a pattern of codes in a complex software program.

As such, it shares a trait common to all programs, and that’s bugs. In other words, it’s a perpetual work in progress. It’s never completely free of bugs. In fact, you don’t know what the bugs are until users expose them or bring them up. To make matters even worse, some of the bugs are intermittent, lying dormant for weeks or months and suddenly popping up when least expected.

This is where debugging in the form of creativity and problem solving enters the picture. In short, setting up an online course is just the beginning of a long-term commitment to debugging and improving the “code” until the course does what it’s supposed to. It’s not a matter of a semester or two but years, and the process is open-ended, never ending.

This means that abandoning a MOOC or online course because it fails in the first go around is like expecting a software program to work perfectly the first time it’s used. It’s never going to happen.

A great online course is great because it’s always evolving even after many years. It never stops growing and changing. By the same token, a poorly designed course can only get better IF the debugging is effective. Thus, teachers, students, and administrators really need to be patient and give the process a chance to evolve.  Continue reading →

The End of Dark Energy

Posted on April 17, 2015 by JimS

Editor, Science Education

Dr. Peter A. Milne and his associates have found an unexpected and, to the cosmological community, startling result from their surveys of supernovae. This result illustrates both the consistent and varying nature of science at the same time.

Dr. Peter Milne

Dr. Peter Milne

We know from a great many astronomical observations that the universe has been expanding for a little short of 14 billion years and continues to expand. Because of gravity, everyone expected that this expansion was slowing over time with theories and measurements suggesting that this expansion would eventually coast to a very dilute universe drifting apart at ever slower speeds.

In the 1990s, some astronomers separately discovered that the universe is expanding ever more rapidly instead of the expected opposite slowing of expansion using measurements of he brightness of very distant supernovae. They received the Nobel Prize in physics for this work in 2011.

Stars can explode. One common explosion is called a nova. A much more cataclysmic and extremely brighter explosion is a supernova. Supernovae shine with a brightness that can exceed that of all of the hundred billion or so stars in its galaxy. For this reason, we can see them in distant galaxies that are barely visible in our best telescopes. A supernova is a rare event occurring about three times a century in a galaxy the size of our Milky Way. With hundreds of billions of galaxies, however, it’s not too hard to find hundreds each year using modern astronomical equipment.

A special sort of supernova created when the two stars in a binary star system go through a specific series of interactions is known as a type 1a supernova. Because of the steps required to reach supernova status, the brightness of these type 1a supernovae has been considered to be a constant that can be used to estimate distances to very distant galaxies. Brightness declines with distance in a very precise manner.

There remains the possibility that acceleration of very distant bodies in our universe away from each other is a basic property of our space-time structure not detectable at smaller distances of only millions or even tens of millions of light-years, that “dark energy” is just an attempt to recast a phenomenon into understandable terms, just as the caloric theory of heat was long ago. -HK

The measurements of these supernovae were the reason to believe that the expansion of the universe was accelerating. We are seeing these very distant supernovae with light that started its journey over ten billion years ago when the universe was very young. Dr. Milne has discovered that type 1a supernovae are not all the same but fall into two categories of different brightness. Furthermore, the supernovae from the early universe are, on average, less bright than those in the more recent universe.

The lower brightness of the distant supernovae may well be due to less inherent brightness instead of greater distance. This finding destroys a fair piece of that Nobel Prize discovery. Dr. Milne still attests that the universe’s expansion is accelerating, just not so fast, but the vast number of recalculations being done to account for this new discovery will take some time.  Continue reading →

Life on Frozen Moons

Posted on March 21, 2015 by JimS

picture of Harry KellerBy Harry Keller
Editor, Science Education

Now that three of the moons of our solar system’s gas giant planets have been said to have subsurface oceans, it’s time to take stock and consider the meaning of these analyses.

Ganymede and Europa of Jupiter along with Enceladus of Saturn are likely to have oceans far below their frozen surfaces. Should we send unmanned missions to explore these unusual moons, and what should we be searching for? Many have exclaimed that we have extremophiles (organisms that survive in extreme environments) here on Earth, so we cannot discount the likelihood of life beneath miles of ice where the Sun never shines.

This image or video was catalogued by Jet Propulsion Laboratory of the United States National Aeronautics and Space Administration (NASA)

Enceladus’ north polar region. This image was catalogued by NASA’s Jet Propulsion Laboratory.

If we search near the geysers of Enceladus, might we find the frozen remnants of miniature fish coughed up from deep down inside this odd moon? Answering this question requires more than a moment’s thought. What is life? How does it begin and advance? Are the ingredients for life available in those cold, deep seas?

Here’s my definition. Life uses available energy and materials to reproduce itself and has the potential for errors in reproduction that will allow for evolution. From what we know, those vast, cold underground oceans have the necessary ingredients. Without an energy source, they would be frozen and not liquid. Heat coming from the inside of a moon must provide chemicals that can both be used as chemical energy sources and as materials for constructing living organisms.  Continue reading →

Does SETI Make Sense? Part IV: Communicating

Posted on March 10, 2015 by JimS

Harry SETI header

We are likely to be the only civilization in our galactic cluster if the chances of forming such a civilization are but one in ten trillion. These are not encouraging numbers. For the sake of argument put the odds up to having 100 civilizations in our galaxy. That’s lots more than I would expect and means that the estimates are way off, by a factor of 10,000. Such an improvement in estimates certainly is friendly to SETI. But, can we contact one of these other civilizations?

Although I think that SETI is a colossal waste of resources, I cannot fault those who pursue this dream.

The galaxy is a very large place, about 100,000 light-years across. Any civilizations will be in an annulus around the center because being close to a galactic center is inimical to life. We won’t be able to communicate to the other side of our galaxy due to the extreme noise originating at our galactic center. Our potential range for communication is probably about 20,000 light-years, but this range again is limited by the number of noisy objects between us and our target.  Continue reading →

Does SETI Make Sense? Part III: Evolution

Posted on March 9, 2015 by JimS

Harry SETI header

Every planet that develops life based on chemistry similar to ours will begin with single cells. The entire water ecosystem will consist of these cells in some variety. That variety necessarily came about due to errors in copying the cells from one generation to the next. They would have a rather mundane life of drifting about randomly until encountering some useful molecule and absorbing that molecule. When enough of these molecules had been absorbed, possibly taking years, the single cell will divide into two.

In this slow, inexorable process, the seas will become full of these cells. Some will drift to inhospitable places where they’ll be killed and spill their contents back into the sea for other cells to absorb. Direct conflict is unlikely because the apparatus for killing and absorbing other cells is too complex to develop readily.

Altogether, there’s something like a chance in a billion that a given star will have a planet that can develop and sustain life. The chances are probably much worse.

Early on, after about a billion years, some developed the ability to use sunlight to make molecules from CO2 and water, from chlorophyll, probably an early form that has evolved into its many varieties today. Some scientists suggest that the earliest versions of chlorophyll did not produce oxygen as a byproduct. By about 2.3 billion years ago, some definitely had and started putting oxygen into the water. For life at that time, oxygen was a serious poison, worse than cyanide is to us. It was a matter of adapt or die — or hide somewhere where oxygen did not exist.

This was probably the first great extinction on Earth, and it was caused by oxygen pollution. Evolution favored those who had a way to neutralize this nasty chemical. Slowly but surely, the removal of so many anaerobic species left ecological niches open, and aerobic cells began to fill them. They used a new way to create energy though oxidation, a much more efficient way than their predecessors. Unfortunately (or fortunately from our viewpoint), the oxygen had some other side effects.

Does SETI Make Sense? Part II: Life

Posted on March 8, 2015 by JimS

Harry SETI header

The question of what is life has puzzled us for centuries. A new movie, Chappie, addresses this issue in the context of what is a spirit or a soul. Life is simpler but still can be awkward. Because we’re seeking to find civilizations that send out radio waves, we can limit our ideas of life somewhat. Life could be defined as something that reproduces itself using available energy and material resources. To be useful, this life should also be capable of making reproductive mistakes that lead the way to evolution. Without evolution, that civilization could not appear.

In order to figure out if SETI makes sense, we must gather some sort of estimates of the probability of life starting and of it evolving into something like us. We must also determine how many stars harbor planets capable of supporting such life.

Before beginning this peregrination of thought, consider that our version of life here on Earth consists of organisms spawned in water and built of carbon, oxygen, hydrogen, and nitrogen plus some other elements in smaller proportions. Any life must be capable of a complex chemistry and of building rather extensive molecules. Finally, the basic construction materials should be close at hand and in reasonable abundance.

Hydrogen is the most abundant element in the universe and constitutes nearly all of its normal matter. It is found in important simple compounds: water, ammonia, and methane. These also are the simple compounds in which oxygen, nitrogen, and carbon reside. While some have suggested that alien life chemistry might use silicon in place of carbon, the much greater abundance of carbon argues against that route. Similarly, water is not only abundant on the Earth but also throughout space. It has the advantage of being an excellent solvent and the odd characteristic of expanding upon solidifying so that lakes freeze from the top down. All of these features make water the best medium for harboring life by a large margin.  Continue reading →

Does SETI Make Sense? Part I: Numbers

Posted on March 7, 2015 by JimS

Harry SETI header

Understanding SETI (the Search for Extraterrestrial Intelligence) requires that you become involved in a great many different fields and comprehend some rather difficult concepts. For most, it becomes a matter of faith, just what science is not all about. This series of articles attempts to make sense of it all, to put you in a position of deciding on a rational, not faith, basis whether SETI is worthwhile or a waste of time and money. They also provide the basis for some interesting class discussions. Enjoy.

Carl Sagan

Carl Sagan

Carl Sagan famously was a strong supporter of SETI and even wrote a novel that put the best possible face on it. For many like Sagan, the benefits of simply knowing that other intelligent life exists out there overwhelms the negatives of cost and time. What do you think? Will you have a different opinion when you have finished reading these articles? Read on.

The first problem with addressing SETI and similar issues revolves around the huge numbers involved. They truly are astronomical. For SETI, we have to have an idea of how many planets in the universe may be capable of harboring life. Our galaxy, the Milky Way, has over 100 billion stars, possibly much more. The universe also has over 100 billion galaxies. These are huge numbers indeed, but the total number of stars in the universe is their product, greater than ten sextillion.

In case you haven’t heard of a sextillion, it’s a one followed by 21 zeroes. To get an idea of how big that number really is, consider a few examples.  Continue reading →

MOOC Sightings 004: Outside the Box with Ontario’s Judy Morris

Posted on February 28, 2015 by JimS

MOOC Sightings2
Updated 3/1/15
As in all things MOOC, look northward to Canada for the prevailing winds, and this time it’s to Ontario, and more specifically, to president and CEO of Lambton College Judy Morris. “Over the last few years,” she says, “Ontario colleges have seen enrollment in online learning grow ‘exponentially higher than on-ground learning.'”1

Judy Morris, President and CEO of Lambton College, Ontario.

Judy Morris, President and CEO of Lambton College, Ontario.

Granted, she’s talking about online courses and not MOOCs, but the difference is superficial. In all but name, online courses are MOOCs that have been literally stuffed into the concrete and glass boxes that define traditional classrooms. In the box, they are subject to the same start and finish dates, registration requirements, enrollment caps, credit policies, fees, and even pedagogy that fail miserably at mimicking F2F (face-to-face) interactions.

Is it any wonder, then, that online courses fare so poorly in comparison to blended courses? As they’re currently positioned, completely online courses are simply poor copies lacking the features that make onground courses so effective for those who can afford to be on campus and attend classes in person for four to six years.

For the promise of online courses, we need look no further than MOOCs. There are some obvious differences: MOOCs attract huge enrollments and there’s usually no cap to class size, registration is free, anyone can register, they’re usually shorter than the standard quarter or semester, there’s no F2F requirement, feedback is provided by peers, they don’t count toward a degree, and they appeal primarily to nontraditional students.  Continue reading →

MOOC Sightings 002: Oxford Professor Declares MOOCs the Loser

Posted on February 22, 2015 by JimS

MOOC Sightings2

William Whyte, professor of social and architectural history at St John’s College Oxford, assures us that in the “battle” of MOOCs vs traditional campus-based universities, “The MOOC will prove to [be] the loser.”1 He parades the usual suspects for their demise: low completion rates and absence of credits and degrees.

He tosses Britain’s E-University and Open University in with MOOCs for what amounts to a clean sweep of online programs. Two birds with one stone, as it were. He cites E-University as a costly failure and Open University as “actually a rather traditional university.” Convenient, but what these institutions have in common with MOOCs is baffling.

He bolsters his prediction with survey results: “Only 6% of prospective undergraduates surveyed last year [want] to stay at home and study. The other 94% expected and hoped to move away to a different place for their degrees.”

Whyte declares traditional universities the winner because “people want and expect something rather more than a purely virtual, entirely electronic experience of university. They expect it to be a place.”

Strong reassurance, indeed, for those who see MOOCs as “a horrible sort of inevitability.” Traditional universities have not only withstood the MOOC challenge but actually emerged stronger.  Continue reading →

New Exoplanets Very Old

With all of the hoopla over exoplanet discoveries in recent years, it’s a big surprise that this one did not receive more attention. Kepler-444 is a small star, about 25% smaller than ours, and is 11.2 billion years old. According to measurements made by the 600-million dollar Kepler space telescope, it has five rocky planets ranging in size from Mercury to Venus.

The above information is sufficient to generate great excitement. When you realize that the universe is only about 13.6 billion years old, you know that this star and its planets formed in the early days of a very young, only about 2.5 billions years old, universe. Our own star is less than half as old at 4.6 billion years and has an expected lifespan of around 10 billion years.  Continue reading →

‘Better Than Earth’? – Baloney

Posted on December 29, 2014 by JimS

picture of Harry KellerBy Harry Keller
Editor, Science Education

“Superhabitable” worlds may be common in our galaxy, making ideal homes for extraterrestrial life — Scientific American cover, January 20151.

Years ago, Carl Sagan famously wrote about a scientist’s “baloney detection kit” in The Demon-Haunted World (1995). You can learn all about this storied chapter by searching on the Internet for “baloney detection kit.” His point was that scientists obtain this mental tool kit as a side effect of their training and that we should similarly train everyone.

Scientific American magazine just published an article, “Better than Earth,” which shows us that scientists are not immune from broadcasting baloney themselves at times. The article is really quite good and interesting. Its statements are, as far as we can tell, accurate. Where is the baloney then?

At one point, the article states, “[T]he more closely we scientists study our own planet’s habitability, the less ideal our world appears to be.” The article also faults our own star’s “short” lifetime of about 10 billion years. “By some 1.75 billion years from how, the steadily brightening star will make our world hot enough for the oceans to evaporate, exterminating any simple life lingering on the surface.”

Looks as though we evolved just in time to enjoy our planet for a billion years or so before we are all steamed to death. Slower evolution may not have left enough time for us to exist here.

We circle a G-class star. According to the author, the next step down in star size, “K dwarfs[,] appear to reside in the sweet spot of stellar superhabitability.” K dwarf stars will shine for tens of billions of years, many times longer than our star. However, the author cautions that our planet is too small for conditions suitable for life to exist for that long period of time. Our core would have cooled too much to sustain our magnetic field and plate tectonics, both necessary to life.  Continue reading →

What Sort of Intelligence?

Posted on December 8, 2014 by JimS

picture of Harry KellerBy Harry Keller
Editor, Science Education

You may have noticed recent news about Stephen Hawking predicting the demise of the human race due to the rise of artificial intelligence (AI)1. Others of genius rank, such as Elon Musk and Ray Kurzweil2, have also made this prediction. With “The Theory of Everything” (biopic about Prof. Hawking) in theaters right now, this prediction is resonating across the English-speaking world.

Before digging your shelters or heading for the hills, you should ask, “What is artificial intelligence?” A bit of history may help put this entire subject into perspective. The term was coined in 1955 by John McCarthy, who called it “the science and engineering of making intelligent machines.”3 “When?” you ask. “That’s nearly 60 years ago! Before I was born!” (I actually was born well before then, but statistically you probably weren’t.)

Funny how AI has not taken over the world in the 60 years it’s had so far. Why the sudden worry? Computers are becoming more powerful and less expensive. Computer memory is dirt cheap, speaking historically. This trend of more computer power and more memory shows no signs of abating soon. Could it eventually reach the tipping point where machines are sentient and self-reproducing? Would they then remove the “scourge” of humans from the Earth’s surface? Might the end be less dramatic in that they would render people superfluous? Imagine a world in which all work, including creative work, is done by machines. Who needs Beethoven when you have the Ultra-Composer Mark IV?

This entire discussion circles around to defining machine intelligence and estimating exactly how smart machines might become. Right off the bat, understand that intelligence, as we commonly understand it, has not been seen in machines yet. No one truly knows if it ever will be. To comprehend why, you must have a feeling for the nature of computers and computing.  Continue reading →

‘The Theory of Everything’ – A Hollywood Take on Science

Posted on November 1, 2014 by JimS

picture of Harry KellerBy Harry Keller
Editor, Science Education

The new movie, The Theory of Everything, is about the life of Stephen Hawking from his graduation from Oxford to his becoming famous and then separating from his devoted wife of over a quarter century. Please, everyone, go to this movie. Why? Because it’s a good story, well acted and directed, and because you will be supporting the concept of telling the stories of scientists in movies. We must have more of this.

Stephen has a special resonance with me for strictly non-scientific reasons. We were born in the same year. We both entered prestigious colleges at the same age, 17, and went on to prestigious graduate schools for our doctorates. We were both married in the same year, he to Jane and I to Jayne. Of course, there are innumerable differences to balance these few coincidences. I majored in chemistry, he in physics. I have enjoyed rather good health overall. He is outrageously famous, while I labor in obscurity. And so it goes.

The Theory of EverythingBefore getting to the science, I’ll praise Eddie Redmayne for his uncanny portrayal of Stephen Hawking. From the early stumbling to the later crablike fingers and the difficulty in forming words, he nails Hawking in a manner that I never would have believed. Especially moving are the scenes in which he has the twinkle and slight smile showing Hawking’s personal joy at special moments and his puckish sense of humor.

This is a wonderful love story in which personal connection overcomes insurmountable odds. Jane (Wilde) Hawking’s (played by Felicity Jones) indomitable spirit lifts Stephen Hawking to the threshold of his greatness. We see this spirit and unwillingness to give up displayed several times in the movie. The very fact that Jane has three children, the last when Stephen is unable to move from his wheelchair speaks volumes about her. Ms. Jones brings a real sense of what the actual Mrs. Hawking must have felt to many of the scenes in the movie.  Continue reading →

The Issue of Part-Time Community College Students

Posted on October 5, 2014 by JimS

Jim ShimabukuroBy Jim Shimabukuro
Editor

For college students in general, a 2011 survey found that 75% are part-time. Of these, “Even when given twice as long to complete certificates and degrees, no more than a quarter ever make it to graduation day.”1 Another study in 2012, focusing on community college students, found that 59% are part-time. Of these, 42% work more than 30 hours a week, 37% care for dependents 11 or more hours a week, and 40% take evening or weekend classes.2

In comparison to full-time students, part-timers fail at over twice the rate in completing certificate and degree programs. Here’s a breakdown from the 2011 survey:

part-time

Considering their numbers and their low completion rates, it’s a wonder that community colleges continue to do business as usual, with little or no change in practices that date back over half a century.

Thus, I was pleasantly surprised to find, in my college emailbox, an announcement that I’ve been returning to, off and on, for the past few days. It is a call for proposals to address the problem of part-timers. The proposed plan has to either (1) assist part-time students earn 12 credits in an academic year or (2) shorten their time-to-degree. The deadline is close and the form is complicated, so I won’t be submitting a proposal. But I do have some thoughts on this subject.

From a part-time student’s perspective, college is only one of a handful of other responsibilities with higher priorities. S/he has to be able to fit it into her life, and not the other way around. The problem is that colleges are set up for traditional students whose main priority is to complete a program. So, like a square peg, she’s trying to fit into a round hole.

The courses she needs are either filled or offered at a time that’s not convenient for her. Offerings at night or on weekends are slim pickings. Even when she can fit a class in, she finds it difficult to meet deadlines, complete learning activities, or obtain learning assistance. Competing for her time are work and family demands. Furthermore, the commute to campus is all too often time-consuming and, if she drives, the cost of gas and limited parking stalls are an ongoing concern.

The fact that our hypothetical part-timer is among the majority of students who are poorly served should be an incentive to change, from a perspective that’s campus-centered to one that’s student-centered. In other words, colleges ought to be asking, How can we accommodate part-timers with their unique needs?

The title of the 2011 report mentioned above goes to the heart of the problem — “Time Is the Enemy.” The traditional college schedule is the enemy of the part-time student. It’s in one dimension, while part-timers are in another. Put another way, part-timers make up a completely different population that isn’t being served by the colleges as they are now. Put in still another way, part-timers are an open invitation for disruption, for a disruptive approach that will accommodate the needs of a large population of students who are currently being ignored.  Continue reading →

Dinosaurs Among Us?

You may have noticed one of the many articles such as this one that cast doubt on the asteroid (or comet) strike that annihilated the dinosaurs. Oh, the asteroid did the job, they say, but it had some help.

Careful examination of North American fossil records strongly suggests that the dinosaur population was under stress from lower than usual herbivore diversity. What say?! There just weren’t as many plant-eating dinosaurs as usual, which means that dinner for the large meat-eaters was a bit harder to come by.

The Earth was undergoing extreme changes 66 million years ago when the great impact took place. Massive volcanic eruptions in what is now India were the result of a collision of the Indian and Asian continental plates. Climate was undergoing change. And dinosaur herbivore diversity was down.

The above was really no big deal. Dinosaurs had been around for well over 100 million years and had survived many environmental challenges. This was just another that would kill off lots of individuals and perhaps a few species. As a whole, the dinosaurs would come roaring back soon enough, however.  Continue reading →

Martian Rhapsody: Chapter 2 – Rocks

Martian Rhapsody
by Harry E. Keller, PhD

CHAPTER 2
Rocks

The four hopeful settlers stare open-eyed at the vista that confronts them. Mars stares back, red-faced and malevolent. They discern nothing friendly or helpful in that stare. Some might see indifference, but they’d be wrong. If ever mankind faced evil, it is here in this impossibly alien and lifeless environment.

Even the dark, sharp-edged rocks strewn across the landscape with apparent reckless abandon seem infused with baleful intent, waiting patiently for countless eons for these soft Earthlings, waiting to cut them and trip them. The surface between the rocks is red, not the red of a poppy or even an Earth sunset, but an intense red that fills the land with emanations of harm. Despite the extreme thinness of the atmosphere, the strangely close horizon does not immediately and sharply turn to the black of space as on the Moon. The red dust of Mars hangs in the sparse air and softens the horizon just enough to give the appearance of red sand reaching up, an almost living thing.

As if sensing the planet’s personality, Chun speaks up, “We have to get that module back so we’re at full strength.”

“You bet!” responds Dawit excitedly, pumping his fist. He is undaunted by the landscape or the problem of the errant module.

“Sure,” says Aleka, “but first we have to put our habitat together.”

“Sorry,” says Chun as she moves into position.

“We all feel the same. All right, we’ve practiced this plenty of times,” says Aleka.

“Seems like thousands,” responds Dawit with a gesture none of the others can see because he’s inside.

“We don’t have all that long before our suits have to be recharged,” warns Balu.

“Right. Let’s rotate and connect,” says Aleka.

“Good thing that missing module connects at the end,” comments Chun.

“The rovers have done a nice job of clearing the site and putting the modules in place,” says Balu.

“I cannot wait to get a plan for the missing module,” comments Dawit over their intercom. Everything is an exciting adventure for Dawit.

Unite or Die

Posted on May 5, 2014 by JimS

For at least two centuries, education has been divided up into separate compartments. In most recent educational history, the so-called core compartments or “subjects” have been social studies, English (now known as English language arts or ELA), mathematics, and science. Along side these have been physical education and a number of other artistic or artisan activities such as music, drama, art, and woodworking.

A great number of educators have noticed that this separation has made less and less sense as time has passed. Similar issues exist within these disciplines. For example, my own area of science was divided up long ago into physics (the original natural philosophy encompassing motion, light, and other physical phenomena such as electricity and magnetism), chemistry (changes in matter), and biology (study of living things that was mostly limited to classification in its earliest days). Biology has changed enormously and now no longer depends on classification. Understanding chemistry requires plenty of physics and often heavy-duty mathematics. And so it goes.

If we are to educate our youth, we must break down the artificial barriers between the compartments formed so long ago. They make little sense these days.

For example, mathematics and science are kept separate in our schools, and their teachers are trained separately. Yet, mathematics, as taught in grades K-12, is mostly applied mathematics at its heart. It was created for commerce, engineering, and surveying. Calculus was created for science. These connections are lost in most mathematics courses. Once you’ve learned to count, that is, learned the names of the numbers, the rest follows logically as you begin to figure out the world around you. Were science and math merged into a double-period class, it could make much more sense to students — especially if engineering is included in science, and commerce is included in math.  Continue reading →

Can America’s Wasted Talent Be Harnessed Through the Power of Internet Based Learning?

Posted on November 14, 2013 by JimS

For nearly 150 years, the American dream of a better life of economic success and advancement has been found largely through the narrow path of higher education. However, access to traditional higher education has always been limited to the top one-third of the adult population and by all indications will continue to be rationed at this level or less into the foreseeable future. Peter Smith, in his 2010 book, Harnessing America’s Wasted Talent: A New Ecology of Learning, points out that while traditional higher education will continue to serve this segment of the population, educational leaders must find alternative ways that will effectively meet the postsecondary education needs of a much larger segment of the adult population.

Smith is not alone in this thinking. There have been numerous reports in recent years that have also called for greater access, flexibility, credit portability and increasing degree completion for a much larger percentage of the adult population. In addition, many of these reports place a special emphasis on closing the growing achievement gap, which is increasingly leaving Latinos and African-Americans behind other groups when it comes to earning college degrees. Why is this important? There is a strong and growing consensus among policy makers, educators, economists and scholars that, if this country is to remain an economic superpower, a much larger and more diverse segment of the adult population must be better educated.

America’s current workforce is aging and retiring, and 85% of all new jobs now require some college education. A real crisis is rapidly developing  — America is finding itself with an escalating gap between the increasingly sophisticated workforce skill demands of the new economy and what the average American worker has to offer. In a 2011 report, The Undereducated American, Georgetown University professors Anthony Carnevale and Stephen Rose provide a strong argument that America will need a dramatic increase in the number of individuals with college degrees within the next decade. This increase in college graduates, according to Carnevale and Rose, is not only needed to help sustain the nation’s economic growth but will also help reverse the 30 year trend of growth in income inequity.

However, with the downturn in the economy over the past six years, we are once again reminded that a college degree alone is not a complete guarantee against economic challenges or underemployment. Economic growth and viability cannot solely depend on education. Nonetheless, according to the Bureau of Labor Statistics, the greatest predictor of personal income and employability for Americans still is, and will continue to be, their level of educational attainment.  Continue reading →

The First Step in Educational Change Is Unlearning

Posted on January 14, 2013 by JimS

Jim ShimabukuroBy Jim Shimabukuro

Like gold, we horde what we’ve learned about education and expect to live off the interest for the rest of our professional lives. Tossing it out with the garbage is unthinkable. Crazy. Yet we also know that we can’t re-envision or change education as long as our slates are filled with the dusty remnants of prior learning.

Jim Finkelstein, in “Simple Minds Think Alike: The Art of Unlearning Complexity” (Huff Post, 4 Jan. 2013), says that “Unlearning how things have been done in the past, while seemingly unnatural is entirely possible….When it comes down to it, the stuff that gets us stuck in the first place is what we’re striving to unlearn…. All it takes to change and escape from a habitual rut is a single thought or idea that is swimming in the opposing direction of everything you’ve ever learned or been taught.”

The idea of unlearning, of wiping the slate clean, of “swimming in the opposing direction” to envision change is not new. It has a long tradition in Eastern philosophy, and educators such as Karen Windeknecht and Brian L. Delahaye, in “A Model of Individual and Organisational Unlearning” (Proceedings 18th annual Conference of the Australian and New Zealand Academy of Management, 2004), say that “The major reason for encouraging or engaging in unlearning is to allow the inclusion of new information or behaviours, and as a means to assisting learning, innovation and change” (3).

Emily J. Klein, in “Learning, Unlearning, and Relearning: Lessons from One School’s Approach to Creating and Sustaining Learning Communities” (Teacher Education Quarterly, winter 2008), defines “unlearning” as “letting go of deeply held assumptions about what it means to be a teacher, what classrooms look like, what the essence of teaching and learning is” (80). However, unfortunately, she leaves us with a bit of  wiggle room to keep some of the old stuff on the slate by saying that “a certain amount of unlearning or changing of beliefs is necessary for any school reform” (95).
