Agreed. I think there are enough tools that "explain" a concept. Not enough tools to apply those concepts and test. Good point. Also agree on giving two hoots

Agreed. I think there are enough tools that "explain" a concept. Not enough tools to apply those concepts and test. Good point. Also agree on giving two hoots about students. This is one of the reasons edtech generally is hard to monetize. If you monetize, you come off looking like making money off kids. If you don't monetize,how do you make the best product. I think the Khan academy approach of a non profit makes the most sense. Commercialization of education through edtech has had disastrous effects atleast in India(ex: Byjus etc)
