Thanks, I am somewhat the wiser. But this sentence on that wikipedia entry surely doesn't mean what it says.
The extent of the economy over traditional "talk-and-chalk" teaching is not yet clear, but for instructors without web development expertise, using a VLE absorbs less time and produces a more professional result.
Surely that can't be actually comparing talk-and-chalk with a VLE and saying VLE is less time consuming for teachers with no web development expertise? What web development expertise is necessary to teach in a class with a board and books etc? Methinks there is either something missed out of that sentence or some underlying assumption which is not made clear, and I's confuseled.
