Re: Replacing Humans

Depends on what level you are talking about. There is close to zero advantage to having a lecturer explain first year calculus to 450 students. That practice should be eliminated immediately and replaced with Khan (or Khan like technology).

It's embarrassing how many higher level education institutions haven't cracked that part of the puzzle. Save the budget and populate the Math Labs with (reasonably paid) Grad Students where the students are doing exercises, instead of paying (a typically horrible at presentations) mathematics professor to "Teach".

Agreed. A major benefit that seems to be recurrent in the pilot schemes is the data the Khan system provides, and how that allows teachers to interact with students in a more personal and efficient maner. The net result being less kids fall behind. However that also shows the need for the human interaction.
