In the past, I’ve touched on a distinction I see in the landscape of higher education. It is this distinction that leads me to say that programs like Coursera and edX and programs like Udacity and the Georgia Tech OMS are not competitors, but rather represent two largely different goals of education: openness and quality.
Of course, I hate using the word ‘quality’ because it implies that open education cannot be high-quality, which is not what I mean to suggest. Rather, what I mean to suggest is that openness and quality often get in the way of one another. Developing open courses for a platform like Coursera almost inherently dictates that costs must be extremely limited. Offering a course through Coursera does not bring in a tremendous amount of money; even the Verified Signature track, I would speculate, barely pays for the human effort required to grade assignments and verify identities. Developing open courses can be an act of either marketing or altruism, but in either case, there is a natural impetus to keep costs low. The outcome, of course, is nonetheless fantastic: the world’s knowledge presented by the world’s experts on that knowledge in a venue that everyone can access. Even if the cost pressure demands that this information can only be presented in the traditional lecture model, the outcome is nonetheless incredibly desirable.
That openness is largely driven by the internet’s ability to deliver content to massive audiences for low costs. However, that’s not the only thing that the internet can do in service of education. The internet also has features and frameworks that can create educational experiences that go beyond what we can do in traditional classrooms. Many traditional college classes are delivered in the same lecture model as the aforementioned Coursera courses, but pedagogically we know that this model is largely ineffective. It is not chosen because it is effective, however; it is chosen because professors’ time is valuable, professors are very often experts in the subject matter rather than in teaching itself, and the lecture model is arguably the easiest way to present material. There are exceptions, of course, but I don’t think I’m being controversial in suggesting these ideas as generally true.
What the internet gives us, however, is a mechanism by which content can be produced once to be consumed by millions. This is part of the reason the openness initiatives work: professors can film the course once and make it available to the masses rather than having to reteach it semester to semester. But while in some places that is an impetus for openness, we may also use that as an impetus for quality. Let’s invent some numbers to make it clearer. Let’s imagine that a class of 50 students are each paying $100 to take a class; this means that the class must cost no more than $5,000 to deliver each semester. However, if the class could be developed once and re-used ten semesters in a row, that means that the same class now can cost up to $50,000 to develop, allowing for much more investment into the quality of the class.
This, of course, is a gross simplification, but it is intended to portray an elegant truth: when we use the internet to deliver content to a much larger population with the same amount of work, we can either pass on the savings to the students (the openness route), or we can reinvest the money into the development of the courses themselves (the quality route). We can ask less investment of the students, or we can give the students more for the same price.
Coursera, edX, and the traditional MOOC community take the former, providing content for a fraction of the cost because it can be delivered to so many people. Udacity, the Georgia Tech OMS, and other more expensive programs take the latter approach, reinvesting that money into creating higher-quality programs in the first place. Both these sides are critical. I don’t like living in a world where education is gated by such a massive monetary investment, and MOOC services are doing a world of good to reduce the barriers to education. At the same time, I love education itself, and I recognize that there are phenomenal things that the internet can do to improve education — but they come with a significant development cost.
Of course, this hasn’t actually answered the question: I’ve shown how openness and quality are distinct and often conflicting goals in online education, but can we accomplish both? Is it possible to create high-quality education that is also openly available for little to no monetary cost? It may be. At present, this is in some ways what the Georgia Tech OMS is doing: nine Georgia Tech courses are available for free to the world, and they are infused with a more significant initial investment that pays significant dividends in the quality of the instruction. This is accomplished because, in some ways, this free offering is “subsidized” by the students taking the actual Masters. This model is incomplete, however, as there is still valuable education locked within the for-cost program. OMS students are not paying for the videos; they are paying for the access to professors and TAs, the access to projects and assignments, and the ultimate “verified certificate”: the Masters diploma at the end of the program. However, this direction at least illustrates that it may be possible to use one offering in service of the other and improve both openness and quality at the same time. For now, however, I regard the two as distinct, exclusive, and desirable goals.
