[Maths-Education] Re: Fwd: The Khan Academy

[Alexandre Borovik]

Some time ago I posted a post in my blog "Mathematics under he Microscope",

"An “average word problem” in the Khan Academy": 
http://micromath.wordpress.com/2011/05/28/an-average-word-problem-from-the-khan-academy/

with analysis of randomly chosen problem from the Khan Academy website.

It appears to be relevant for the current thread.

With best wishes -- Alexandre
