Hi James! As you reference, reframing an answer so that others can build on the response not only positively affects a student's self-esteem, but it creates momentum in the learning environment. Unless a student is completely off base, no answer is worthless. I shutter when instructors simply say "No" or "Incorrect" and move to the next student response.
Thanks for your observations,
