How often do you need signaling indicators, though? If someone has sufficient competence at a given field, they should be able to demonstrate that competence by delivering satisfactory work.
The proof should be in the level of understanding of the concept of slope acquired by students using various methods; it doesn't matter at all who is "right" with respect to some formal definition.
- ghshephard 14y agoTotally agree with you that what matters is whether the students eventually grasp the material. What I like about Khan, is he is fundamentally interested in teaching students so they _understand_ the material. He doesn't get caught up in theories of pedagogy or mathematical models or precise correctness - he sees his job is to communicate a concept in a way that the student says, "Oh, I get it." Now, with that said - there _is_ a danger in that model of teaching, in which the student gets lured into a zone of comfort. So there _absolutely_ is a place in teaching for instructors who are going to challenge, upset, and disturb the student - resulting in a form of stress that pushes to the student to new heights. This can be a very uncomfortable (and, indeed, upsetting/stressful) learning environment - but it does give students deeper, and sometimes much more meaningful insight into topics. But that's not what Khan's about. He is the guy you go to when you just want to get over some hurdle about a topic that has frustrated you.
