I'm not seeing how is the failing rate on his course. Only that near 30% of the students signed the letter. It is maybe that number?. 30% failing rate is not bad, yes, the education community must to do something about those students concerns (maybe opening a pre orgo course or offer some tutors), but if that is the failing rate is not bad. What I'm saying is that when you are teaching the failing rate is something you must to lower, not lowering the quality of your course, but being flexible with your teaching system. I'm not seeing why you should remove the teacher here. And that is bad.
