How else should a teacher’s effectiveness be judged other than helpfulness? Helpful in teaching students how to ask great questions, teach them how to experiment, plan, be interesting, be concise, and share their curiosity. Introducing Dave’s online math course: Linear Systems and Matrices. In this course, Dave is your biggest cheerleader.
