I have been trying to figure out how many courses are given a year in the US. I can’t find that data anywhere – so I decided to try and guesstimate it. Since there are about 7000 colleges in the us (I found this number here) I took that as a starting point. I am also guessing a low ball number of the average number of courses given yearly by a single college – say 500 (I actually think that the number is much larger – but maybe someone can set me right). After some simple multiplication – there are about 3,500,000 courses given in the US a year! For a world wide market I am guessing you need to quadruple that for around 12,000,000 college courses being taught a year worldwide!. That is around 120,000,000 lectures – and it doesn’t even count lectures given in high school and various other venues – so it really is a lowball estimate. I am hoping someone out there in the ether can tell me if I am hallucinating or not.
There are about 1200 courses available through MOOCS (I found that data here). I can’t find any data on lecture capture – but hey lets be generous and say 10 times that for 12,000 courses captured via lecture capture a year worldwide. So together they capture about 1% of the courses worldwide. That leaves students with a gap of only 11,985,000 courses not being captured through any media – isn’t that a shame?
The only way to start capturing the other 11,000,000 courses is to crowd source it through students. Isn’t it time to start?
