I assumed Khan, an OER, would be a household name given all the PR he has had and yet 60% of the people I talked to over the past 2 months either hadn't heard of him or knew his name but not what he does. And as good as Khan is and the great supports he has now, he approached all lessons the same way; through tutorial videos. Yes, they can be watched any time and any where as many times as a student wishes but it is still only one approach.
