Cheating on exams can be controlled in some ways better than large conventional courses through the use of video cameras and computer software.
MOOCs offer a way for administrators to lower the cost of college.
Students are less polite in their communications. While a face-to-face encounter softens our criticisms, electronic media acts to disassociate personal responsibility from the conversation and the results can range from uncomfortable to downright nasty. This behavior, seen also on bulletin boards, blogs and chat rooms is known as “flaming”.
When students take a live class they usually have the opportunity to meet with their advisor and teachers; they live in an environment that supports the goals of learning and are thus more motivated to attend the course.
A video lecture provides no nonverbal feedback to the teacher from the students (blank stares, gazing out the window, sleeping) and thus the teacher cannot take steps to make the presentation more interesting (take a few minutes break and ask the student next to you to explain a concept that is still puzzling).
It takes a teacher in the range of 100 to 200 hours to produce one hour of video; this requires a huge startup cost and commitment by the teacher. Interestingly this has not changed much since the ‘70s.
Although MOOCs may be a way for administrators to lower the cost of college, they threaten to replace teachers — thus jobs are lost and the unions are busted.
Initial data show completion rates are low — in the 10 to 20 percent range.
Assuming the Cons can be addressed, MOOCs seem to be the wave of the future, but take a moment to recall the promises made about TV in the 1940s and even into the 50s. TV was going to replace bricks and mortar schools and we could all be educated from home. And what do we have now: five hundred channels of Infotainment, at best. My guess is that we will see hybrid systems with a mixture of live and online classes which will vary by discipline — there are good reasons to deliver a poetry and a science course in different ways.
