  • My open letter to SJSU Philosophy

    Sat, 2013-05-04 15:29 -- John Hawks

    On Thursday, the Philosophy department of San José State University released an open letter to Michael Sandel, instructor of a Harvard edX MOOC. I reacted to the letter in my post, "Lessons in social justice from MOOCs". I combined a statement of approval for the SJSU department's aims with some pointed disagreement about the logic behind their arguments.

    Since that post, I have gotten questions from several people asking me to expand upon my comments. One of the faculty members in the SJSU philosophy department, Janet Stemwedel, is a friend and blogger, who herself pointed to her department's open letter: "My department and a MOOC". My own role at UW-Madison is broader than my development of the MOOC course ("Announcing my MOOC, Human Evolution: Past and Future"), I have also been involved in faculty discussions about the role of online education more generally. With this dual role, I wanted to take some time to detail how I believe MOOCs may fit within higher education and how faculty governance should react to technological innovations and funding challenges.

    I have framed my comments as an open letter in reply to that from the SJSU philosophers (at the Chronicle of Higher Education, "An Open Letter to Professor Michael Sandel From the Philosophy Department at San Jose State U.".

    My open letter

    Let me reiterate that I support your department's position, and hope that you are successful in pressuring your administration to support your teaching mission more effectively. I take an active interest not only as a MOOC instructor but also because I am chair of the curriculum committee of my college. Our major issue this year has been the role of online learning in our programs and departments. These interests have made me examine the open letter very closely. While I agree with much of it, I disagree strongly with its premise and central claim that MOOC developers like me are endangering education. Your department's letter is not the first to spread this mischaracterization, but as an open letter to a MOOC instructor, it targets me directly. Having been miscast in the role of department-dismantler, I feel I must speak out.

    I have been watching developments in California, where the discussion of MOOCs has focused so strongly on both economic and pedagogical issues. Like San José State, UW-Madison also has many online degree programs and blended courses, and a large fraction of our classroom-based courses use online elements. This is not at all new, and we emphasize serving our student community better by providing flexibilities and access to information that we cannot easily provide in the classroom. At UW-Madison, we are very cognizant of other UW institutions with different missions and student populations, including some very popular online degree programs. These now include a state-level initiative to establish a new "flex degree" that would provide an avenue for people to receive a degree by applying real-world experience. As in California, Wisconsin institutions are working to find the best way to serve our students and advance our mission in this changing landscape.

    The best parts of the open letter emphasize your department's teaching strengths, service to your diverse student community, and importance of online innovations in your own teaching. You don't need to offer Sandel's MOOC, JusticeX, because you are doing a better job in your mission than his course could do. I share your department's concern that curricular changes be approved and directed by faculty, not administrators.

    "Knee-jerk guild thinking"

    But I think some other parts of the letter misfire. Critically, the letter neglects entirely the major contribution of faculty oversight to the accreditation process. The parts of the letter that address public versus private universities have many omissions, and are ultimately counter-productive by raising the specter of elitism. In reality, public universities, including some small public universities, have been among the earliest innovators of massive online courses. Also, by framing the issue around this Harvard edX course, the letter neglects the participation of the University of California in edX. Here you miss an opportunity to clarify your position. Would your department be just as resistant to a MOOC created with the use of California tax dollars? I suspect it would, just as I sense that many of the "well-funded" versus "poorly-funded" arguments are oblique references to the very specific UC versus CSU divide. Illuminating those issues more concretely would have strengthened the letter more than the hand-waving arguments about employers wanting job training instead of liberal education. In surveys of employers who actually hire our students, we find quite the opposite: Employers want college graduates to have the thinking and writing abilities instilled by a liberal education.

    I disagree most strongly with the letter's final call to action:

    "It is in a spirit of respect and collegiality that we are urging you, and all professors involved with the sale and promotion of edX-style courses, not to take away from students in public universities the opportunity for an education beyond mere jobs training. Professors who care about public education should not produce products that will replace professors, dismantle departments, and provide a diminished education for students in public universities."

    That final paragraph, like the letter, is addressed to Sandel. As a result, it targets me and anyone who is creating open educational resources. Your department's letter urges me to stop creating my MOOC. It claims that my course "will replace professors, dismantle departments, and provide a diminished education for students in public universities."

    I disagree.

    This is knee-jerk guild thinking. It says that I should serve the interests of tenured professors at other institutions before I serve my own students, my discipline, or the public.

    With its open letter, your department is promoting among the public a misconception that I and other MOOC instructors are destroying the value of a traditional education. My interpretation is not a misreading, it is an inevitable consequence of the department's decision to write an open letter addressed to the instructor of a MOOC. That's me.

    Learning with a MOOC

    I have obligations to the public, who provide me a job, facilities, funding, and paid for my training. I have obligations to my own teachers, who generously shared their time and wisdom far beyond the strict requirements of any mere job. I have obligations to my department and to my university, to advance their missions and make the best use of their resources. I have an obligation to my students, to make the most effective use of my training and technology to involve them in the forefront of learning, including the research in my discipline. If I followed the call to action in the open letter, I would be cheating all these people.

    My MOOC course will incorporate footage and interviews from the field, graduate student field journals, and some massive participatory science that involves students directly in research. This investment will yield many beneficial effects: My classroom courses will use some of the material in a blended format, some materials will plug into the new K-12 Next Generation Science Standards, we will publish and share research on the MOOC itself, and those insights will help improve existing courses and develop new courses for our UW-Madison students, including in my own department. This is a really good investment of our resources. It serves our own students and the public of Wisconsin, our research mission, and an international audience who may lack the resources to attend any institution of higher education.

    Neither I nor anyone else is imagining that another institution will take my MOOC, clap on a teaching assistant, and charge students tuition to take it. I personally think such a plan would cheat students by charging them for learning they could do for free.

    Still, I can imagine other scenarios that I would heartily encourage. For example, an instructor who is conducting field research for five weeks during the regular semester, might use five weeks of my MOOC as instructional materials during that time, supervised by a local TA. That would allow the instructor to bring more research experiences into the classroom, and probably would allow that instructor to provide deeper coverage of some topics where my resources are strong. The materials will be open, and I want other professors to use them to improve their students' experiences and their own opportunities. The flexibility of the open approach makes such uses possible, yet necessarily creates the risk that an institution will attempt to capitalize on the content by charging students for a credential in exchange for minimal additional instruction. If the alternative is that students at a small institution have no ability to integrate the subject of human evolution into their degree program, I wonder if this "risk" is a bug or a feature.

    The problem of the pre-packaged course

    Your department's open letter is focused on the use of "pre-packaged courses", because of the particular situation your department faces. Although I agree with your department's position, I note that this problem is neither new nor limited to MOOCs. The same problem has most notably been associated with textbooks. An instructor that adopts a commercial textbook may now be offered a package that include online lectures, quizzes, exercises, Powerpoint presentations, and study forums. These resources are neither open nor gratis. The costs are directly borne by students, through high textbook prices, which they pay over and above any tuition and fees. A department that adopts a mandatory textbook for its introductory course is essentially requiring its students to subsidize a "pre-packaged course", supervised by a local instructor, who may or may not be a professor with expertise in the subject. I do not have a general attitude about whether a MOOC should fit a similar role as textbooks for professors who are not content experts. But I do believe we are better off having more free and open high-quality learning resources, and that any learning resources should be used in for-credit courses only with faculty oversight.

    At UW-Madison we have discussed this issue extensively as part of our discussions about online learning. Neither my college nor university advocate a one-size-fits-all approach to this question, as we leave the judgment about course materials to departments and faculty with oversight from cross-department faculty committees. Many commenters on the MOOC phenomenon fail to note the extensive history of using non-classroom experiences within college degree programs. We already accept transfer credit from a wide range of institutions, under long-standing higher education agreements, which include online and distance courses. We provide ways for students to receive academic credit for examinations (such as the AP tests), and we facilitate students carrying out academic projects in conjunction with service learning, internships, and field experiences. Whether or not we eventually accept MOOCs for credit, they will have to follow the same governance and oversight structures as these other long-established mechanisms.

    Intrinsic to that oversight process is an unhindered ability of faculty to say, "no." Again, I applaud your department for making its pedagogical decision clear, based on the needs of SJSU students and the broader learning community. Your department is showing that the system works, a demonstration more important than the specifics of this single case. I hope that your administrators hear your message clearly.

    Still, I hope the next department to say, "no", can find a way to do so without asking innovators to stop.

    My considered reaction to the suggestion that I may be destroying education
  • Lessons in social justice from MOOCs

    Fri, 2013-05-03 00:34 -- John Hawks

    The Philosophy department at San Jose State University have written an open letter to Michael Sandel, a Harvard teacher of government and lauded lecturer. Why is this news? Because Sandel is the teacher of one of a massive open online course (MOOC), and the San Jose philosophers don't want to use his materials in their courses. The New York Times and Chronicle of Higher Education cover the story, and the Chronicle has published the open letter..

    From the Times account:

    “The move to MOOCs comes at great peril to our university,” the letter said, “We regard such courses as a serious compromise of quality of education and, ironically for a social justice course, a case of social injustice.”

    While expressing respect for Dr. Sandel’s scholarship and teaching, it also chided him, saying, “Professors who care about public education should not produce products that will replace professors, dismantle departments and provide a diminished education for student in public universities.”

    I basically agree with these philosophy professors. As their letter makes clear, these philosophers are already making extensive use of blended learning and online materials in their courses. They object to having their work outsourced. I would go further: They should not shirk their jobs to guarantee the quality of education for their students, and the accreditation of San Jose State depends on them doing that job properly.

    But they use faulty arguments in their letter. If a department is so dysfunctional that it is endangered by some YouTube videos, it probably needs to be dismantled. And surely it is a perverted idea of "social justice" to demand that a professor stop providing a free public good, just because professors at other institutions feel threatened?

    They would be better served to document the ways they advance learning, making it clear why those functions cannot be replaced wholesale by an online resource. As for my MOOC, I hope the materials will be reused as widely as possible.

  • Paleofuture radio MOOCs

    Fri, 2013-04-26 08:03 -- John Hawks

    The Chronicle of Higher Ed takes us to a time in the past, when massive radio correspondence courses were the wave of the future, including at my alma mater, Kansas State: "Before MOOCs: 'Colleges of the Air'".

    Finally, even when students endured the isolation and passivity of this new mode of learning, conquered the temptations of popular radio programs, and finished a course, it wasn’t clear what that meant. Students in Kansas State’s radio classes received certificates verifying they had participated in “the college of the air,” but these were not the same as real diplomas. Other colleges tried to make the classes count for university credit: Between 1923 and 1940, 13 institutions offered courses for credit, and nearly 10,000 students enrolled. But a mere 17 percent actually received credit, and by the 1940-41 academic year, there was only one radio course in the United States for which a student could earn credit—and nobody enrolled in it.

    Things have changed technologically, of course, which brings distance education within the learning patterns of more and more students. In my one course, starting in January, already as many students are signed up as the entire number that enrolled for credit in these 1930's radio courses nationwide. We won't be offering credit in this go-round, but that landscape is also changing rapidly.

  • Mailbag: Director's cut

    Tue, 2013-04-23 21:51 -- John Hawks

    Re: online learning:

    For your consideration with respect to educational productions: I wish that, instead of the annoying Commentary track (where the actors/director tell about how they were drunk when they shot that scene) there were a 'Geek track' available on documentaries. It would show the actual finds, skeletons, radiocarbon data, images...whatever was appropriate for the Viking, dinosaur, asteroid being discussed. For every scene, you could get the scientific 'backstory' as well as the dramatic portrayal.

    I think that this would be an excellent method to provide actual education to people who were eager for the next Vikings/dinosaur/anthropology/physics documentary. It would provide an easy transition between the cgi of the production and the data of the scientist.

    Great idea, similar to my tweet the other day, we can imagine a world where every factual claim was accompanied by the opportunity to back it up immediately with data.

  • Mailbag: Student attention spans

    Tue, 2013-04-23 21:49 -- John Hawks

    Re: "Student attention spans are variable":

    This has been a subject which has given me food for thought increasingly as I have grown older. I still attend a few medical talks where I work, but the problem is not just attention. It is wakefulness too. It seems unrelated to the subject matter. Excluding external factors such as how much sleep the night before, and activity levels previously during the day, I have come to the conclusion that some bright spark could devise an algorithm based on a number of factors.
    1. Room temperature, especially a gradual rise due to x students cooped up for x minutes
    2. Lighting levels; presentations involving slide shows often require low lighting
    3. Oxygen levels falling in a room full of listeners, all breathing out carbon dioxide, and doors shut
    4. The dreaded post-lunch 2pm spot.
    5. Interaction levels

    I am sure a p50 levels, based on when half the audience's heads are nodding could be calculated.

    P.S. of course this does not appply to your lectures

    I totally agree!

  • Student attention spans are variable

    Tue, 2013-04-23 10:29 -- John Hawks

    There is much discussion in online education about the "15-minute rule": that content longer than 15 minutes will lose students' attention. Part of this is because of the intrinsic pain of watching videos on a computer. But part is rooted in classroom observations, that students in lectures tend to become distracted and lose their attention for a lecturer after some period of time. Interestingly, the education research shows that this is more complicated. For example, Karen Wilson and James Korn [1] found that individual variations among students swamped any time effect for attention and effective recall or note taking.

    It is clear that students' attention does vary during lectures, but the literature does not support the perpetuation of the 10- to 15-min attention estimate. Perhaps the only valid use of this parameter is as a rhetorical device to encourage teachers to develop ways to maintain student interest in the classroom. If psychologists and other educators continue to promote such a parameter as an empirically based estimate, they need to support it with more controlled research. Beyond that, teachers must do as much as possible to increase students' motivation to “pay attention” as well as try to understand what students are really thinking about during class.

    Probably the most useful bit is this:

    The information processing that occurs during classroom tasks resembles a large working memory task (D. J. LaVoie, personal communication, March 21, 2005). Students receive information from the instructor and must hold the information long enough to record it in their notes or do whatever else they need to do with it. Whether students will be able to maintain their attention in class depends on their working memory capacity as well as their motivation and arousal (Pashler, 1998).

    This suggests that instructors should provide multiple cues to promote effective use of working memory during their classroom presentations. Specific callouts to reading materials -- preferably search terms in an ebook -- might be helpful. And visualizations ought to be consistent between lecture and readings, so that students can calibrate their note taking.

    As for online presentations, I still think that short is better. But more to the point, they should also be calibrated to other material, such as online readings and quizzes, so that note taking will be more productive.

  • Are MOOCs technical or practical?

    Tue, 2013-04-09 12:42 -- John Hawks

    All the NY Times columnists will be writing about MOOCs before long, I suspect. Today it was David Brooks' turn: "The Practical University". His argument is that digital technology allows much more efficient transmission of "technical" know-how than do classrooms in big buildings, but "practical" know-how cannot be taught without real hands-on training.

    The problem is that as online education becomes more pervasive, universities can no longer primarily be in the business of transmitting technical knowledge. Online offerings from distant, star professors will just be too efficient. As Ben Nelson of Minerva University points out, a school cannot charge students $40,000 and then turn around and offer them online courses that they can get free or nearly free. That business model simply does not work. There will be no such thing as a MOOC university.

    Nelson believes that universities will end up effectively telling students: “Take the following online courses over the summer or over a certain period, and then, when you’re done, you will come to campus and that’s when our job will begin.” If Nelson is right, then universities in the future will spend much less time transmitting technical knowledge and much more time transmitting practical knowledge.

    Like many NY Times columns about education, this one reads like a paid advertisement -- in this case for Minerva University. That doesn't mean that it's wrong, but I don't think the practical-technical distinction holds. In anthropology, for example, it is possible for us to use digital tools to bring much more of the experience of the field to students than we can accomplish in the classroom. I also think the "technical-practical" distinction breaks down when considering laboratory work.

    I think a basic rule of thumb is to ask whether the analogy works for sports. In sports, we have broadcast events seen by millions, and coaching clinics that scale down to individuals. It takes lots of experience and practice to perform a sport well..and it also takes some experience and practice to watch a sport well. But watching and playing are not the same kinds of activity. They can enhance each other, feed back on each other, and both can contribute to broader appreciation. And digital tools can help with both of them -- they're just different digital tools.

  • Massive courses: massive opportunity or massive problem?

    Sat, 2013-04-06 11:42 -- John Hawks

    Dan Ariely is an economist at Duke University who has been teaching a massive open online course on behavioral economics to 140,000 students, titled "A Beginner's Guide to Irrational Behavior". He recently sat down with the PBS NewsHour to answer questions and share perspectives about the MOOC: "The Plusses and Pitfalls of Teaching Online". It is a long piece with many useful parts, here's a sample:

    there's a great deal of room for variance once you have over 140,000 students in a class. There's a substantial probability that at least some students will be engaged, knowledgeable, thoughtful, and passionate about the class. And indeed, the discussion boards for my online class show just this -- a select group of students truly stand out as motivated individuals who are taking the content seriously and thinking critically about how ideas can be developed and applied to the real world.

    In this regard, the diversity of backgrounds is also a huge benefit in online classes that are available internationally. We hear from students of different ages from around the globe who have so much to contribute. And they not only contribute by sharing their perspectives with their professor and teaching staff, but also with their fellow students.

    Ariely also discusses some of the negatives of a very large student sample: the greater likelihood of disgruntled students looking to draw attention in a public forum, for example.

    This is a really concern for me as I prepare my course, "Human Evolution: Past and Future" (which I announced here earlier this week). A fraction of my students may have goals that include promoting creationist or fringe ideas, for example.

    We are working on some strategies in both the design of the course and the materials that will help to focus students of all backgrounds on the science, while hitting their learning level appropriately. That aspect of the course will really be an important target of our assessment and research efforts. Can we engage this diverse audience productively, increasing science and evolution literacy while stemming possible attempts to derail the process?

  • Announcing my MOOC, Human Evolution: Past and Future

    Mon, 2013-04-01 15:54 -- John Hawks

    I have begun a project that may change the way we teach and communicate the science of human evolution. Starting in January, 2014, I will be offering a massive open online course titled, "Human Evolution: Past and Future".

    This course and all its materials will be open and free for anyone, anywhere in the world. As of this moment, more than 6500 people have already signed up for the course. The course is still more than nine months away, and I'll be developing materials across the entire time up through January.

    Developing this course is a huge investment for me. My institution, the University of Wisconsin-Madison, is making it possible -- but at the same time I'm actively seeking out partnerships and sponsors. I'll be documenting the development process here on the blog, and in a series of presentations and publications as I go. Massive open online courses (MOOCs) have begun to change the way universities approach online education, and the course will be a research platform as well as an educational experience.

    What will be new in this course:

    Expert interviews. I'll be assembling and curating a series of filmed interviews with experts in paleoanthropology to talk about their work. Why should students hear me describe other people's work, when I can engage the scientists themselves? I've already begun these interviews, and will be adding more than thirty by the time the course begins.

    Mini-documentaries. To the extent possible, I'll be virtually taking students to the field, into the laboratory, and giving first-hand experiences with the materials of human evolution. That means many of my video presentations will be much more like short documentary productions than lectures. My priority is making the real materials as available as possible.

    Guided laboratories. We'll be exploring genome data, providing some excellent virtual laboratories with the fossil evidence, and running experiments with evolutionary change.

    Participatory science. With a worldwide group of thousands of students, we'll be giving people the opportunity to participate in some real research. Some will be as simple as massive measurements of body proportions. Others will be more involved, leading us to...

    Looking to the future. The course title is "Human Evolution: Past and Future." To me, the path of our evolution in the past is closely tied to where our species may be going. To that end, the course will be looking at the next hundred, thousand and ten thousand years of our evolution. I'll be interviewing people who are thinking about the impact of technology on our future evolution, and students will come up with their own scenarios based on a strong understanding of the forces that shaped human evolution in the past.

    I'm doing this because human evolution is important. The effects of the past shape who we are today, our health and choices, our societies and imaginations. Anthropology can engage people in their own lives and experience. The MOOC technology platform has such potential for innovating new forms of education, I am eager to bring human evolution into that space.

    And who wouldn't jump at the opportunity to reach tens of thousands of people looking for information about our evolution? Some people really don't like the word, MOOC. All I have to say is, I got used to "blog", so why not another strange word? This is a natural extension to what I've been doing for nine years here on my blog: curating and writing reactions to the best research in paleoanthropology. In this project, I'll be able to bring people virtually out to the field, and let experts tell about their findings in their own words.

    What you can do:

    Sign up for the course. I encourage everybody to sign up! You don't have to finish a MOOC, or even watch all the materials, to get a lot out of it. My MOOC will allow you to "choose your own adventure" to the maximum extent possible. If you want a strong module on ancient diets, you can get that by itself, or together with my best materials on Neandertal genetics and post-agricultural evolution.

    Look for your opportunity to help. I'm working on several partnerships for this course, and the most important one is with you. With a worldwide group of students, many from developing economies, I cannot assign a traditional textbook. I need a free version of everything written for the students in the course, and that means I'll be providing the text myself. I'll be providing some opportunities to help support this important cause, which will impact students everywhere.

    Adopt the materials. We're putting a lot of work into the materials for the course. A lot of professionals are donating time to be interviewed, and are allowing me to use photos and other materials to make a really high-quality presentation. I want to get these high-quality materials into as many classrooms as possible. If you're teaching human evolution in a college or high school setting, look out for additional information on how to use materials and develop curriculum that works in your context!

    I learned a lot from my experiment last year putting lectures online from my regular course. I am putting those insights together with discoveries from other MOOC experiments to create new ways for students to network with each other and with ongoing science. This is just the initial announcement. As the summer progresses, I'll be giving you more background about how I'm producing the course, along with sample materials and some chances to participate. I'm looking forward to the experiment, and I hope you will follow on the journey.

  • Tribulations of online course approvals

    Thu, 2013-03-14 12:44 -- John Hawks

    John Thelin writes in Inside Higher Ed about the process of developing online courses: "Professors and Online Learning".

    The official approval process was markedly different from the course preparation experience. It combined the slow pace of regular course proposal with added delays in deliberations because it was a Distance Learning course, especially at the higher levels of universitywide review. Approval and encouragement came promptly from my department and our college curriculum committee and from my dean – all of whom had an interest in having our college venture into online courses – and who understood that time was of the essence if an online course were to be available soon to students. However, at the next levels, the Senate committee reviews involved little in the way of acquiring skills or rethinking teaching design or course substance. It was characterized by objections or clarifications about relatively small details and was marked by long periods of waiting for word of approval to go on to the next step.

    After subcommittee review, the most surprising finding was that in the Senate Council, and the full Faculty Senate, there were obstructionist colleagues.

    There are some really useful ideas in this essay, which is mostly optimistic about the role of online learning in the future of college education. An essential point that must be made more widely known is that effective online courses are not cheap to produce. It is much, much cheaper to pay a faculty member to walk into a seminar room and conduct a discussion than it is to pay the same faculty member to produce watchable online content, design and monitor online forums that allow effective student interaction, and receive the supplemental training necessary to make everything consistent with university policies on accessibility.

    Can the outcome justify the expense? Not in every case, and universities should think about how they contribute to a broader landscape of online curricular materials. They also need to think about what materials can be effectively reused by other instructors besides the one who designs them. These aspects require much more thought than the typical decisions about course readings and resources for classroom-based courses. In fact, the major use of many online resources will be to supplement classroom experiences in other universities.
