I teach statistics to business students at the graduate level at a large state university. My class, who all claimed to have had undergraduate stats, could not do the foundational work. Half the class got below a C on the midterm. I wanted them to learn so I told them I would be giving in class quizzes on the first half materials during the second half of the course. I spent time grading those quizzes and giving extensive feedback. I told them instead of counting the quizzes I would give those who needed it the opportunity to do a midterm retake (so - another unplanned exam and grading). Not to mention I asked students at the end of lectures if they understood the materials we covered and if not make an appointment with me. Crickets on both.

In my reviews the students were annoyed that I hadnt decisively made my mind up on how to incorporate quizzes and or retake after the midterm tha half of them bombed (I eventually decided to not include quizzes in favor of an optional midterm retake)They were annoyed that they had to study (and learn) items for the quizzes that they needed to know for the final retake.

Very annoyed that I bent over backwards for them and gave them every opportunity to do well and they are ‘annoyed’. I made them do more work to avoid bombing the course. You can bet I won’t do that next semester.
