Science misinformation is being spread in the lecture halls of top universities

Should universities remove online courses that contain incorrect or misleading information?

There are lots of scientific controversies where different scientists have conflicting views. Eventually these controversies will be solved by normal scientific means involving evidence and logic but for the time being there isn't enough data to settle a genuine scientific controversy. Many of us are interested in these controversies and some of us have chosen to invest time and effort into defending one side or the other.

But there's a dark side of science that infects these debates—false or misleading information used to support one side of a legitimate controversy. To give just one example, I'm frustrated at the constant reference to junk DNA being defined as non-coding DNA. Many scientists believe that this was the way junk DNA was defined by its earliest proponents and then they go on to say that the recent discovery of functional non-coding DNA refutes junk.

I don't know where this idea came from because there's nothing in the scientific literature from 50 years ago to support such a ridiculous claim. It must be coming from somewhere since the idea is so widespread.

Where does misinformation come from and how is it spread?

Higher education for all?

I discuss a recent editorial in Science that advocates expanding university education in order to prepare students for jobs.

I believe that the primary goal of a university education is to teach students how to think (critical thinking). This goal is usually achieved within the context of an in-depth study in a particular field such as history, English literature, geology, or biochemistry. The best way of achieving that goal is called student-centered learning. It involves, among other things, classes that focus on discussion and debate under the guidance of an experienced teacher.

Universities and colleges also have job preparation programs such as business management, medicine, computer technology, and, to a lesser extent, engineering. These programs may, or may not, teach critical thinking (usually not).

About 85% of students who enter high school will graduate. About 63% of high school graduates go to college or university. The current college graduation rate is 65% (within six years). What this means is that for every 100 students that begin high school roughly 35 will graduate from college.

Now let's look at an editorial written by Marcia McNutt, President of the United States National Academy of Sciences. The editorial appears in the Nov. 11 issue of Science [Higher education for all]. She begins by emphasizing the importance of a college degree in terms of new jobs and the wealth of nations.

Currently, 75% of new jobs require a college degree. Yet in the US and Europe, only 40% of young adults attend a 2-year or 4-year college—a percentage that has either not budged or only modestly risen in more than two decades— despite a college education being one of the proven ways to lift the socioeconomic status of underprivileged populations and boost the wealth of nations.

There's no question that well-educated graduates will contribute to society in many ways but there is a question about what "well-educated" really means. Is it teaching specific jobs skills or is it teaching students how to think? I vote for teaching critical thinking and not for job training. I think that creating productive citizens who can fill a variety of different jobs is a side-benefit of preparing them to cope with a complex society that requires critical thinking. I don't think my view is exactly the same as Marcia McNutt's because she emphasizes training as a main goal of college education.

Universities, without building additional facilities, could expand universal and life-long access to higher education by promoting more courses online and at satellite community-college campuses.

Statements like that raise two issues that don't get enough attention. The first one concerns the number of students who should graduate from college in an ideal world. What is that number and at what stage should it be enhanced? Should here be more high school graduates going to college? If so, does that require lowering the bar for admission or is the cost of college the main impediment? Is there a higher percentage of students entering college in countries with free, or very low, tuition? Should there be more students graduating? If so, one easy way to do that is to make university courses easier. Is that what we want?

The question that's never asked is what percentage of the population is smart enough to get a college degree? Is it much higher than 40%?

The second issue concerns the quality of education. The model that I suggested above is not consistent with online courses and there's a substantial number of papers in the pedagogical literature showing the student centered education doesn't work very well online. Does that mean that we should adopt a different way of teaching in order to make college education more accessible? If so, at what cost?

McNutt gives us an example of the kind of change she envisages.

At Colorado College, students complete a lab science course in only 4 weeks, attending lectures in the morning and labs in the afternoon. This success suggests that US universities could offer 2-week short courses that include concentrated, hands-on learning and teamwork in the lab and the field for students who already mastered the basics through online lectures. Such an approach is more common in European institutions of higher education and would allow even those with full-time employment elsewhere to advance their skills during vacations or employer-supported sabbaticals for the purpose of improving the skills of the workforce. Opportunities abound for partnerships with industry for life-long learning. The availability of science training in this format could also be a boon for teachers seeking to fill gaps in their science understanding.

This is clearly a form of college education that focuses on job skills and even goes as far as suggesting that industry could be a "partner" in education. (As an aside, it's interesting that government employers, schools, and nonprofits are never asked to be partners in education even though they hire a substantial number of college graduates.)

Do you agree that the USA should be expanding the number of students who graduate from college and do you agree that the goal is to give them the skills needed to get a job?

Style vs substance in science communication: The science writer perspective

I want to address a recent article on science writing: When editors and scientists meet: communicating science without dumbing it down. The author is Alex Ip and the article is a commentary on a panel session about science writing at the ScienceWriters2021 conference held in early October [Editing experts: How to help scientists meet journalism standards].

Undergraduate education in biology: no vision, no change

I was looking at the Vision and Change document the other day and it made me realize that very little has changed in undergraduate education. I really shouldn't be surprised since I reached the same conclusion in 2015—six years after the recommendations were published [Vision and Change] [Why can't we teach properly?].

The main recommendations of Vision and Change are that undergraduate education should adopt the proven methods of student-centered education and should focus on core concepts rather than memorization of facts. Although there has been some progress, it's safe to say that neither of these goals have been achieved in the vast majority of biology classes, including biochemistry and molecular biology classes.

Things are getting even worse in this time of COVID-19 because more and more classes are being taught online and there seems to be general agreement that this is okay. It is not okay. Online didactic lectures go against everything in the Vision and Change document. It may be possible to develop online courses that practice student-centered, concept teaching that emphasizes critical thinking but I've seen very few attempts.

Here are a couple of quotations from Vision and Change that should stimulate your thinking.

Traditionally, introductory biology [and biochemistry] courses have been offered as three lectures a week, with, perhaps, an accompanying two- or three-hour laboratory. This approach relies on lectures and a textbook to convey knowledge to the student and then tests the student's acquisition of that knowledge with midterm and final exams. Although many traditional biology courses include laboratories to provide students with hands-on experiences, too often these "experiences" are not much more than guided exercises in which finding the right answer is stressed while providing students with explicit instructions telling them what to do and when to do it.

"Appreciating the scientific process can be even more important than knowing scientific facts. People often encounter claims that something is scientifically known. If they understand how science generates and assesses evidence bearing on these claims, they possess analytical methods and critical thinking skills that are relevant to a wide variety of facts and concepts and can be used in a wide variety of contexts.”

National Science Foundation, Science and Technology Indicators, 2008

If you are a student and this sounds like your courses, then you should demand better. If you are an instructor and this sounds like one of your courses then you should be ashamed; get some vision and change [The Student-Centered Classroom].

Although the definition of student-centered learning may vary from professor to professor, faculty generally agree that student-centered classrooms tend to be interactive, inquiry-driven, cooperative, collaborative, and relevant. Three critical components are consistent throughout the literature, providing guidelines that faculty can apply when developing a course. Student-centered courses and curricula take into account student knowledge and experience at the start of a course and articulate clear learning outcomes in shaping instructional design. Then they provide opportunities for students to examine and discuss their understanding of the concepts presented, offering frequent and varied feedback as part of the learing process. As a result, student-centered science classrooms and assignments typically involve high levels of student-student and student-faculty interaction; connect the course subject matter to topics students find relevant; minimize didactic presentations; reflect diverse views of scientific inquiry, including data presentation, argumentation, and peer review; provide ongoing feedback to both the student and professor about the student's learning progress; and explicitly address learning how to learn.

This is a critical time for science education since science is under attack all over the world. We need to make sure that university students are prepared to deal with scientific claims and counter-claims for the rest of their lives after they leave university. This means that they have to be skilled at critical thinking and that's a skill that can only be taught in a student-centered classroom where students can practice argumentation and learn the importance of evidence. Memorizing the enzymes of the Krebs Cycle will not help them understand climate change or why they should wear a mask in the middle of a pandemic.

Remember MOOCs?

We learned back in 2012 that Massive Open Online Courses (MOOCs) were going to transform higher education. People all over the world, especially in underdeveloped nations, would be able to learn from the best university professors while sitting at home in front of their computers. Several companies entered the market with high expectations of earning enormous profits while altruistically educating students who couldn't afford to go to university.

Rethinking medical education at the University of Toronto

Watch two medical educators from my Faculty of Medicine at the University of Toronto. They are being interviewed by Steve Paiken of The Agenda. They rightly deplore the traditional lecture style of learning that's common in my university but their solution is more online learning.

The real problem with medical education is that much of the first two years is based on the "memorize and regurgitate" model that we know is ineffective. The best way to change the system is to use evidence-based methods that emphasize student-based learning. The idea is to teach medical students how to access information and how to interpret it rather than have them memorize facts. When teaching biochemistry, for example, it's pointless to ask medical students to take an exam based on structures and pathways that they will forget the day after the exam.

These two physicians are in charge of reforming medical education. They want to please the students by creating a new way of teaching that emphasizes the way "millennials" want to learn. (Short online courses, no lectures.) You'll watch the entire show without hearing any references to the pedagogical literature and what's known to work. Is there any evidence that undergraduate medical students are experts on medical education? (Hint: ... no.)

If this is the wave of the future, I fear that future doctors are not going to be any more informed that the current crop. They will still not be capable of critical thinking.

The way we teach needs to change, but not this way.

Vision and Change

A few years ago the AAAS (American Association for the Advancement of Science) sponsored a study of undergraduate education in the biological sciences. The study groups published a report in 2011 called Vision and Change in Undergraduate Biology Education: A Call to Action. Since then a number of disciplines, including biochemistry and molecular biology, have been trying to encourage university teachers to implement these proposals. So far, the "call to action" has pretty much fallen on deaf ears. Most professors are reluctant to admit that their teaching needs improvement and they are reluctant to read this report or any other part of the pedagogical literature.

“Scientists should be no more willing to fly blind in their teaching than they are in scientific research, where no new investigation is begun without an extensive examination of what is already known.”

Bruce Alberts, NRC, 1997What could be wrong with this?

The time has come for all biology faculty, particularly those who teach undergraduates, to develop a coordinated and sustainable plan for implementing sound principles of teaching and learning to improve the quality of undergraduate biology education nationwide. The stakes are too high for all biologists not to get involved with this national call for change.

The main recommendations are that we should concentrate on teaching fundamental concepts and principles and not facts and that we should adopt a student-centered form of learning.

The recommendations discussed in this report include the following action items aimed at ensuring that the vision of the conference becomes an agenda for change:

1. integrate Core Concepts and Competencies throughout the Curriculum

• Introduce the scientific process to students early, and integrate it into all undergraduate biology courses.
• Define learning goals so that they focus on teaching students the core concepts, and align assessments so that they assess the students’ understanding of these concepts.
• Relate abstract concepts in biology to real-world examples on a regular basis, and make biology content relevant by presenting problems in a real-life context.
• Develop lifelong science-learning competencies.
• Introduce fewer concepts, but present them in greater depth. Less really is more.
• Stimulate the curiosity students have for learning about the natural world.
• Demonstrate both the passion scientists have for their discipline and their delight in sharing their understanding of the world with students.

2. Focus on student-Centered Learning

• Engage students as active participants, not passive recipients, in all undergraduate biology
  courses.
• Use multiple modes of instruction in addition to the traditional lecture.
• Ensure that undergraduate biology courses are active, outcome oriented, inquiry driven, and relevant.
• Facilitate student learning within a cooperative context.
• Introduce research experiences as an integral component of biology education for all students, regardless of their major.
• Integrate multiple forms of assessment to track student learning.
• Give students ongoing, frequent, and multiple forms of feedback on their progress.
• View the assessment of course success as similar to scientific research, centered on the students involved, and apply the assessment data to improve and enhance the learning environment.

"Appreciating the scientific process can be even more important than knowing scientific facts. People often encounter claims that something is scientifically known. If they understand how science generates and assesses evidence bearing on these claims, they possess analytical methods and critical thinking skills that are relevant to a wide variety of facts and concepts and can be used in a wide variety of contexts.”

National Science Foundation, Science and Technology Indicators, 2008The evidence is in. Whether or not we should change is a no-brainer.

The other two recommendations have to do with implementation .... this is the tough part.

3. Promote a Campuswide Commitment to Change

4. Engage the Biology Community in the implementation of Change

Notice that MOOCs and online learning are not prominent objectives in Visions and Change. You have to wonder why AAAS isn't inviting the members of these study groups to give plenary lectures at their 2015 meeting instead of the President of Coursera [see President of Coursera to give plenary lecture at AAAS meeting]. Maybe they've changed their minds since 2011?

President of Coursera to give plenary lecture at AAAS meeting

The American Association for the Advancement of Science holds a meeting every February. This year the meeting is in San Jose, California. There are four plenary lectures [Plenary Lectures 2015]. Three of them will be given by prominent researchers who will be talking about science. The fourth is by Daphne Koller, President and co-founder of Coursera.

Coursera is a for-profit company offering "universal access to the world’s best education." What they mean by "best education" is MOOCs offered by professors at the "top" universities. There's no evidence to support the claim that the best undergraduate courses for the general audience are those given by professors at Stanford, MIT, Princeton, and Harvard. Indeed, there's quite a bit of evidence that this isn't true.

Daphne Koller is going to talk about The Online Revolution: Learning Without Limits. Keep in mind that at the end of every article published in Science (AAAS publication) there's a small notice stating that, "The authors declare no financial conflict of interest" or statements that clearly spell out the conflicts.

Why is AAAS asking someone to give a plenary lecture about selling online courses from someone with a clear financial interest in promoting her company?

Science education is important and there's plenty of evidence that universities are graduating students who don't understand science and aren't capable of critical thinking. There are hundreds of people whose main research interest is pedagogy and especially science education. They have proposed solutions to the problem and suggestions on how we should change the way we teach. Very few of them think that MOOCs are the answer and very few of them are trying to market their ideas for profit [ Reaching Students: What Research Says About Effective Instruction in Undergraduate Science and Engineering (2015)].

Why not ask some of those experts to address the AAAS meeting and possibly explain what's wrong with canned videotaped lectures? MOOCs are just ways of transferring the way we teach now to the mass market. But what if the traditional way we now teach (lectures) is wrong? Isn't that a question that the delegates at San Jose ought to think about?

Here's Daphne Koller giving a TED talk. Near the end she talks about the importance of "active learning" (student-centered learning). I'm a big fan of student-centered learning. She implies that having students take online courses from "top" educators is consistent with active learning but she's wrong. It's the exact opposite. In my opinion, it's a step backwards and by promoting MOOCs we are going to make it more difficult to convince professors to change the way they teach. Instead, the ones who are good at delivering traditional lectures will bring in money for themselves and their universities.¹ They will be getting the kudos and the teaching awards instead of those who are paying attention to evidence-based methods and trying to improve undergraduate education.


Here's another video. It's an interview with Daphne Koller from June 2013. Listen to the first few minutes and you'll hear a different view of active learning. Here, she explains the concept of the "flipped classroom" where students watch online videos and then come to class to participate in "something that's much more engaging and stimulating, active learning" (4 mins). There's nothing wrong with that except that students could read a textbook instead of watching a video. The important part of the learning is what happens in the classroom and not what happens in the textbook or the taped lecture.

She also explains how they are going to make money (5-6 mins).

Daphne Koller is very fond of repeating the myth that the best courses are the ones taught at the top research universities. (She happens to be a teacher at one of these universities.) I bet she can't prove it unless she's talking about very specialized upper level courses.

On the importance of course evaluations at the University of Toronto

My university (the University of Toronto, Toronto, Canada) recently developed a new policy and new procedures on undergraduate student evaluations [Policy on the Student Evaluation of Teaching in Courses]. The policy was the work of a committee that began with the assumption that student evaluations were a good thing. As far as I can tell, the committee did not spend any time examining the pedagogical literature to see if the evidence supported their assumptions. As you can see from the title of the policy, the assumed purpose of student evaluations is to judge the quality of teaching.

The university has a website: Course Evaluations. Here's what the administrators say ...

Course evaluations are read by many people at UofT, including instructors, chairs, deans, the provost and the president. They are used for a variety of purposes, including:

• To help instructors design and deliver their courses in ways that impact their students’ learning
• To make changes and improvements to individual courses and programs
• To assess instructors for annual reviews
• To assess instructors for tenure and promotion review
• To provide students with summary information about other students’ learning experiences in UofT courses

It is essential that students have a voice in these key decision-making processes and that’s why your course evaluation is so important at the University of Toronto.

Your feedback is used to improve your courses, to better your learning experience and to recognize great teaching.

How to become a better teacher (not)

Here's a video by Dr. Lodge McCammon. He has a website: lodgemccammon.com. Here are his credentials.

Dr. Lodge McCammon is an educational innovator. His career began in 2003 at Wakefield High School in Raleigh, North Carolina, where he taught Civics and AP Economics. McCammon received a Ph.D. from NC State University in 2008 and continued his work by developing innovative practices and sharing them with students, teachers and schools across the world. McCammon is a musician who spends much of his time in the recording studio composing curriculum-based music. His songs and related materials can be found in Discovery Education Streaming. He is also an education consultant who provides professional services, including keynote speeches, presentations, curriculum development, and a variety of training programs.

Watch the video and discuss. I think you can guess what I think. I reject one of the basic premise; namely that online courses are taught by the very best teachers. How do we know who is the best teacher just by watching videos?

Here's a question for your consideration. It concerns "reflective teaching." Imagine that you record yourself teaching an incorrect version of the citric acid cycle or a flawed version of the Central Dogma of Molecular Biology. How many times do you have to watch that video to recognize that what you are teaching is wrong? Is it more than three? Less than ten?

Does the University of Toronto really care about undergraduate education?

My university, the University of Toronto (Toronto, Canada), is huge. We have 60,000 undergraduates making it one of the biggest universities in North America. You'd think that undergraduate education should be a very high priority.

The university publishes an online "newspaper" called the Bulletin every Tuesday and Thursday. It's basically a PR ploy to advertise everything that's great about the University of Toronto. There was a time in the past when the Bulletin had editorials that were critical of university practice and policies but I haven't seen anything like that in years.

The latest issue has a link to an article by the President of the University, Meric Gertler. The title of the article is: Job Ready: U of T is developing new programs to help students succeed after graduation. I want to discuss two things in that article. The first is whether the university really is committed to the goals of undergraduate education (this post). The second is What does "liberal arts education" mean in the 21st century?.

What is bioethics? Is Margaret Somerville a bioethicist or a Roman Catholic apologist?

I had an interesting conversation with a student the other day. She's studying "bioethics" at the University of Toronto. This is a program run by the Deptment of Philosophy.

I asked her to define "bioethics" and she couldn't. To her credit, she immediately recognized that this wasn't right. If she's taking an entire program in bioethics she ought to be able to explain what it was all about. She was then joined by her friend, who is also majoring in bioethics. My colleague, Chris DiCarlo also joined us. He's a philosopher writing a book on ethics.

We described a scenario where I wanted to end my life and Chris was willing to help me. Neither of us have an "ethical" problem with that decision. So why is assisted suicide thought to be a problem for bioethics? If some people don't want to participate in euthanasia then nobody is going to make them? Where's the problem?

Does it only become a bioethical problem if some people want to impose their views on others? In this case, the people who are personally opposed to euthansia want to pass a law preventing me from ending my life with the help of my friend. Our students were puzzled by this discussion. Even though they have taken many courses on bioethics, nobody had ever raised this issue. Isn't that strange? You would think that any program run by a Department of Philosophy would emphasize critical thinking. Sadly, this turns out to be rare whenever the topic of bioethics comes up.

Oops! MOOCs Didn't Work Out So Good for Sebastian Thrun

From Tressie McMillan Cottom at tressiemc [The Audacity: Thrun Learns A Lesson and Students Pay].

Sebastian Thrun, founder of Udacity, one of the most high-profile private sector attempts to "disrupt" higher education discovered inequality this week. Thrun has spent the last three years dangling the shiny bauble of his elite academic pedigree and messianic vision of the future of higher education before investors and politicos. He promised nothing short of radically transforming higher education for the future by delivering taped classroom lessons of elite professors through massive open online courses. So what went wrong?

After low performance rates, low student satisfaction and faculty revolt, Thrun announced this week that he has given up on MOOCs as a vision for higher education disruption. The "godfather of free online education" says that the racially, economically diverse students at SJSU [San Jose State University], "were students from difficult neighborhoods, without good access to computers, and with all kinds of challenges in their lives…[for them] this medium is not a good fit." It seems disruption is hard when poor people insist on existing.

Thrun's goal was to market lectures by "elite" professors at places like Sanford¹. His new company, Udacity, was going to make tons of money by selling lists of successful students to private companies who are looking for talent. Guess what? It turns out that there are lots of disadvantaged students in introductory courses at SJSU who don't learn from lectures given by elite Stanford professors. Who would have guessed?

In case you've forgotten the hype that Sebastian Thrun created when he formed Udacity, read: Sebastian Thrun Will Change Education. And watch the video.

1. My position on this is that the professors at Harvard and Stanford are not necessarily the best teachers. In my field of biochemistry, for example, we have direct evidence that professors at MIT do a horrible job of teaching biochemistry [Where Are the Best University Teachers?]. In my experience, the best biochemistry teachers are often located at small colleges where they pay attention to the latest pedagogical literature and actually read the textbooks they use in class.

Evolution: A Course for Educators: Week One

I'm taking a MOOC! It's called Evolution: A Course for Educators. The principle instructors are Joel Cracraft and David Randle of the American Museum of Natural History in New York (USA).

Welcome to Evolution: A Course for Educators! We’re excited to have almost 13,000 students enrolled in the course and look forward to spending the next four weeks together as we learn about the Tree of Life, natural selection, the history of life, and human evolution, as well as how to incorporate an exploration of these issues into your classrooms.

Judging the Quality of MOOCs

Another journalist has written about Massive Open Online Courses (MOOCs). This one is in The New York Times: Two Cheers for Web U!.

Most of these articles about MOOCs are not very good but this one is different. The author expresses some skepticism and hit the nail on the head when he says ...

But the first thing I learned? When it comes to Massive Open Online Courses, like those offered by Coursera, Udacity and edX, you can forget about the Socratic method.

The professor is, in most cases, out of students’ reach, only slightly more accessible than the pope or Thomas Pynchon.

But that's not what I want to talk about today. I want to discuss the quality of these courses and how you might go about judging whether they are truly teaching the subject correctly.

Here's the problem. Too many people, like A. J. Jacobs, the author of today's article, assume that because the lecturer is famous or from a "top" school, the material must be accurate and up-to-date. As A. J. Jacobs puts it ...

On the other hand, how can I really complain? I’m getting Ivy League (or Ivy League equivalent) wisdom free....

With the exception of a couple of clunkers — my plodding nutrition professor might want to drink more organic coffee before class — most of my MOOC teachers were impressive: knowledgeable, organized and well respected in their field.

Students are not in a position to judge whether a professor is "knowledgeable" about the material being covered in a course. In the case of MOOCs, many students just assume that because the professor is from an Ivy League school then he/she knows how to teach an introductory course properly.

That's a very bad assumption as I've shown when I examined the biochemistry material being taught in the MIT courses Where Are the Best University Teachers?. Same is true for the courses at the Khan Academy.

I'm currently in Boston at EB2013 where I'm hanging out with biochemistry and molecular biology teachers and textbook authors. Many of these experts are not household names but they are the experts in their field, which is teaching. If you really want accurate information about the fundamental principles and concepts in biochemistry and molecular biology then you should take the courses they teach. You'll get a far better education than if you listen to professors from big-name research intensive-universities.

The recent ENCODE publicity disaster is just one example of the fact that top-notch researchers don't necessarily understand the fundamentals of subjects that are just outside of their own area of expertise.

Let's try and put a stop to this myth that the best teachers are professors from Ivy League schools. There's very little evidence to support that myth, especially in fields that I'm familiar with: evolution, biochemistry, and molecular biology,

Mocking Friedman's MOOCs

Thomas L. Friedman is the Op-ed columnist for foreign affairs at the New York Times. He has won three Pulitzer Prizes (1983, 1988, 2002).

According to Wikipedia, Friedman has an undergraduate degree from Brandeis University (Boston, USA) and a Master's degree from Oxford (UK). He taught a class at Brandeis in 2006 but as far as I can tell that's his only experience with university outside of being a student. He does not appear to be an educator and he doesn't appear to have any expertise in pedagogy.

That hasn't prevented him from writing three opinion pieces on the imminent demise of universities and the glorious future of online courses—especially MOOCs (Massive Open Online Courses).

Come the Revolution May 15, 20012
Revolution Hits the Universities January 26, 2003
The Professors’ Big Stage: March 5, 2013

Online Training of Competent, Employable, Bioinformatics Professionals

I think that undergraduate education at most universities is done very badly. There are far too many courses that consist of professors giving standard lectures to large classes with evaluations focused on "memorize and regurgitate" exams. Most courses pay no heed to student-centered learning even though there has been sound pedagogical research showing that student participation leads to better learning. Most courses and programs provide no "value-added" component that takes advantage of being physically located in an enriched scholarly environment. Most courses do not teach critical thinking.

Given the horrible status of most university courses, it's not surprising that they can be replaced by online courses where the student never needs to set foot on a university campus to get the same quality of education. This is not an endorsement of online courses, it's a comment on the poor quality of campus-based courses.

David B. Searls is an "independent consultant" who published an article in PLOS Computational Biology: An Online Bioinformatics Curriculum.

Where Are the Best University Teachers?

Much to my embarrassment, the University of Toronto is promoting online courses, or MOOCs [Online courses for anyone, anywhere]. These courses seem to be for information only—you can't get a university credit for them.

I'm not opposed to offering free "courses" for people who don't have easy access to a university campus. In fact, I think it's a good thing. But let's make sure we distinguish between public lectures and serious education. In my opinion, if the quality of an online course is equal to the quality of a course given on campus then all that says is that the campus-based course is lousy. We should not refer to these online examples as "university courses." They should be labelled as "public lectures."

I'll have more to say about this later but today I want to return to an issue I raised before. Is it true that the "best" universities also do the best teaching? I have suggested that the answer to this question is probabyy "no" [On the Quality of Online Courses] [Is Canada Lagging Behind in Online Education?].

Sebastian Thrun Will Change Education

John Hawks is a big fan of online education. He posted a link to a Wall Street Journal article about online education [Online education and Silicon Valley]. The article, Sebastian Thrun: What's Next for Silicon Valley?, is mostly about a Stanford professor and Google employee, Sebastian Thrun.

The entrance to his building is littered with the gaudy red, blue, yellow and green bicycles that Googlers tool around on. I'm at the secret headquarters of the not-so-secret Google X, where the way-out-there projects of the search giant turn into reality. The gregarious play master, Sebastian Thrun, leads us into a well-worn conference room. The chairs are a shade of green not found in nature and the disrupting clang and cheers from a rousing foosball game waft in through the door. Mr. Thrun, 45 and slight in stature, is sporting a gray T-shirt of a local start-up and speaks softly with German-English diction.

Thrun and his Google colleague, Peter Norvig, taught an online course on artificial intelligence that attracted a huge number of students. Apparently there were 23,000 students who completed the course. That's amazing. But there's more ...

Mr. Thrun's cost was basically $1 per student per class. That's on the order of 1,000 times less per pupil than for a K-12 or a college education—way more than the rule of thumb in Silicon Valley that you need a 10 times cost advantage to drive change.

So Mr. Thrun set up a company, Udacity, that joins many other companies attacking the problem of how to deliver the optimal online education. "What I see is democratizing education will change everything," he says. "I have an unbelievable passion about this. We will reach students that have never been reached. I can give my love of learning to other people. I've stumbled into the most amazing Wonderland. I've taken the red pill and seen how deep Wonderland is."

How in the world do you pay attention to 23,000 students and give them a grade that reflects what they learned for only $23,000? The only way you could do that is to have all assignments and tests evaluated electronically and that's no way to teach properly. (You also need very cheap servers, internet access, and software and Thrun and Norvig have to work for free.)

Udacity is a for-profit company. How will it make money? [Ex-Stanford Teacher’s New Startup Brings University-Level Education To All].

Classes are currently focused on computer science since that’s what the team already knows how to teach. Examples include: Building a Search Engine and Programming a Robotic Car. As one of the inventors of Google’s self-driving car, Sebastian is perfectly suited to teach a class on how to program one. Udacity plans to expand to other subjects with the goal of building a full university online.

All classes are currently free, and the goal is to keep it that way. When asked how it will make money, Sebastian pointed out that recruiting good technical talent is something that companies pay for. Udacity knows who the best students are and could pass them along to companies looking for new hires.

Somehow I doubt that Udacity will be offering courses in philosophy, French, or art history. I don't even think they'll be teaching biochemistry since very few of our undergraduates move directly from a Bachelor's degree to jobs in biotech or pharmaceutical companies.

Sebastian Thrun thinks he's going to "democratize" education but, if he succeeds, what he's really going to do is dumb down and cheapen education. The only thing in his favor is the fact that today's universities are doing the same thing so creating online courses is probably no worse that what students are currently getting in the classroom. If someone can offer the same quality of "education" for much less money then what's the point of attending classes?

Online Courses: The Great Courses

John Hawks has recently blogged about My foray into online education. He's posted videotapes of the lectures in his anthropology course: Principles of Biological Anthropology.

It's interesting to watch his lectures but I think he's avoiding the key question that concerns me about online courses. The question is, should we be delivering traditional "lectures" to students in our classrooms?

I would never allow anyone to videotape my classroom time and post it on the web. That's because my goal is to involve the students in the class and generate discussion. I don't want them to be intimidated by a camera and I certainly don't want the camera to record for posterity the interactions between students as they discuss the basic concepts and principles that come up in class. Sometimes I have to tell a student that there question was interesting but not on topic or, even worse, that it revealed a serious misunderstanding. Do we really want that posted on the course website?

Sometimes (often?) I say something really stupid. It's part of the risk we take when we have a course like the one I'm describing. These are not prepared and rehearsed lectures.
