First of all I did have a teacher in the classroom and any subservient role to the video teacher is entirely up to them. I wasn't proposing the entirety of the course be video. If teachers are teaching to Jose in the back row, then Juan in the front row is being screwed. Jose in the back row is going to end up taking care of people's yards where Juan has a shot at college. By the way the teacher you are describing in your narrative is the best of the best and should not be confused with many of them.
I never even considered that the entire lesson should be pitched solely to “Jose”. I merely used that name as one that a teacher might find in their classes today in an inner city. You don’t find “Sally”, “Dorothy”, “Paul”, “Frank” or “Carl” in classes any more. By no means did I mean that “Jose” stood for all Hispanics. What I meant was that a classroom teacher would throw in a few clarifying remarks for Jose or any other kid who you know is not going to grasp the concept as originally explained. A few clarifying remarks does not an entire lesson make. Your “Juan” in the front row is likely to “get it” as originally explained, but will still benefit from having the concept explained a different way. It is also true that many students claim they understand something, when asked, when the actual situation is nothing of the kind. They were too shy, proud, intimidated to ask questions they should have asked to clarify the concept for themselves. So having a few clarifying remarks made for the sake of “Jose” will actually benefit everyone.
