An Online University? Are you Crazy?

I wish some of the people who are so excited about the prospect of online college courses being taught by famous faculty members understood a little bit more about what a university education is really supposed to accomplish.  The reason students (ought to) go to college is to enhance their capacity to function in the world-at-large once they graduate -- to function as citizens, productive workers, parents and as potential leaders in all walks of life.  When colleges do their job, students learn fundamental skills (like how to master a new body of knowledge, express their views effectively in writing and in spoken terms, and how to listen and respond to others with very different values and beliefs). They are also expected to familiarize themselves with a substantial body of knowledge (the Cannon of Western Literature? Great Books? Key Concepts in Science and Math? Great Moments in History? Competing Theories of Social Change and  Human Progress? ) that educated people use to make sense of what is going on around them.

You can read about all of these things.  There's nothing new about that. And, now we can put these materials and study guides on line.  Big deal.  And, we can capture the best lecturers in the world presenting these materials and post them online so that people all around the world can listen and watch without having to relocate. We certainly do that with recorded music.  But that doesn't a university make!  We wouldn't imagine giving someone a degree in music theory or performance because they had listened to long list of records or disks. Any anyone who thinks that open on-line enrollment in a catalogue of college-level classes equals a college degree, is sadly mistaken.  And, even if we add computer-graded exams to be sure that the many thousands of people taking these on-line courses have read the material, we will still be nowhere near what it takes to master fundamental skills and use a substantial body of knowledge.  Mastery requires real-time interaction with other learners and hands-on coaching by skilled teachers.  It requires, trial and error, feedback and reflective discussion. That's why large lecture classes are almost always supplemented by small sections in which students try to use the skills and knowledge they are reading or hearing about in collaboration with other students and teachers.

There are three reasons that on-line universities or efforts to approximate them will fail.  First, the most important feedback students need takes the form of questions asked, answered and reconsidered in real-time with a cohort of other learners. A list of Frequently Asked Questions with standards responses pre-prepared by instructors won't give each student the opportunity and responsibility they need to try formulating their own questions as they grapple with the material.  Second, students invariably learn more from other students than they do from faculty as they try wrestle with the materials they are trying to learn.  This, in turn, requires a safe and supportive environment in which students dare to ask questions (even if they feel foolish revealing what they don't know) or offer tentative answers to questions posed by others.  This works best when students meet outside of class on a regular basis, study together and  earn each other's trust.  They also need one-on-one time with faculty (or teaching assistants) to talk about assigned materials, review work in progress or get feedback that puts exam results in context and makes sure they figure out why they got something wrong.  Grades (especially when they are machine-generated) can't do that.  Third, when skill development and not just knowledge acquisition is the goal, students need repeated opportunities to try-fail-reflect- and discuss to achieve mastery. Multiple choice, machine-graded exams will never be able to substitute for hands-on faculty coaching and real-time interaction with peer learners.  That's why we need smaller not larger classes (or cohorts of students).

My own university (MIT) is poised to invest tens of millions of dollars in on-line education for the world-at-large. There are some ways in which this could be enormously helpful (and could strengthen residential learning), but merely recording and transmitting on line (even for free) the "best" course in various fields is not going to help very much.  We tried that in the past by writing text books.  People all over the world were encouraged to use the basic economics and physics textbooks developed by MIT faculty. Did that improve and sustain the quality of teaching in other universities?  I don't think so.  The only way to do that is by enhancing the capacity of teachers in those other places and help them enhance their teaching skills.  On-line courses are going to be used as an excuse by college administrators in other parts of the world (and even in the US) to fire faculty members and give students credit for taking on-line courses (offered by MIT and others).  That won't strengthen education in the developing world, for example, it will weaken it.  On the other hand, we could use MITx to create an on-line learning community for economics or physics faculty members around the world.  It would need to be highly interactive.  The focus should probably be on how to meet the culturally-defined learning needs of the students each of these faculty members is trying to teach. An on-line forum -- with the capacity to upload teaching demonstrations by one participant that could become the focus for the larger group to review--would aim to share what we know about teaching key concepts or using various teaching methods.  Strengthening teaching capacity in as many places as possible ought to be our goal, not reducing or eliminating teaching capacity.

I can imagine giving students a lot more video material to look at before classes begin.  I teach city planners about the way certain kinds of resource management challenges can and should be handled.  Seeing detailed video accounts prepared by colleagues all over the world, showing how certain problems were handled, would be a wonderful supplement to the readings I assign.  But, when students come to my class, I will still pose hypothetical scenarios to see if they can use what they have been viewing and reading.  I want each student to be ready to respond to any question another student might ask, or that I might ask.  I want to give them collective feedback on their latest assignment.  I want them to react to the feedback I provided to them individually on the quiz or exam they recently completed. Then, I will ask them to work in teams or small groups to come up with the best response to still another hypothetical situation I have proposed. Finally, I want to gather them together for a cross-group discussion where one person from each group presents their group's "best advice" to the hypothetical client (using everything they viewed or read before class, as well as the ideas that came up during their small group discussion). This is the only way I can help my students master the material I am presenting.

On-line video and other interactive materials can help students prepare for a class or review what
happened in a class, but it can't substitute for the real-time group learning that college education is meant to offer.  Similarly, on-line course, if used correctly by qualified faculty members, can supplement what it taught -- especially if it is accompanied by on-line forums that explain to faculty how they can use new materials to teach their particular students. But, online courses can't substitute for residential (i.e. face-to-face, real-time) learning.

There will never be an on-line university that offers more than minimal vocational training -- learning the material, step-by-step, by yourself, at your own pace and taking a machine-graded test.  That doesn't come close to generating mastery (i.e. an ability to use concepts and methods in an improvisational way). Mastery can only be achieved through trial-and-error-and-coaching-and-correction-and-question-asking in a continuing group of trusted peer learners.

  2. Amen. We need institutions that also adapt with the complexity of our world. Gone are the days when you can just stay primarily within your department. If the bricks and mortar university system is to thrive it ought to learn to better cross-fertilize with other departments so students can better generate new ideas and innovate. Nothing provided online will ever be able to compete with the learning of the creative process, cooperation, collaboration, being in the moment, seeing mistakes as opportunities, listening, improvising and the balance between structure and space that a university setting can provide if done correctly. It's all problem solving but clearly some environments provide better opportunity than others.

  3. I totally agree in the thoughts you have presented here. Though we know that there are a lot of online schools that offer great learning programs, as students, we still want a more conducive and collaborative environment for education. Enrolling to a college online has a lot of advantages but we can't deny that there are also a lot of things essential for an individual that we could never have online.

  4. Online degrees are a great way to further your education and make you more marketable in a job search. While learning from the convenience of your home, it allows you to save travel expense and hassle. Some of the online campuses offer accelerated programs that allow you to learn at your own pace and get completed much quicker.
