I have taught physics and engineering courses using several methods, and I see that many minority students don't like to get engaged in classroom lectures/discussions. I have done demonstrations, jeopardy sessions, made them come up to the board to solve problems, asked them to come to my office hours and still have witnessed many of the students coming to class everday completely lost on what was going on. Are there any professors/instructors out there who have developed a successful approach to getting more minority students engaged in STEM lectures?
