Lack of Standards

In Colleges and Universities faculty members, especially tenured ones, feel that they are masters of the Universe. A faculty member feels that he/she can do things in his/her own way, often with no consideration for students. Pity the poor student who has to take four courses in a term with four different instructors, each of whom follows his/her methods and systems. No wonder students are often confused. I believe in openness and share all my previous exams and grades with students. I do put in a lot of time and effort in creating new questions every time. The other day, two students told me (independently) about another professor whose course they were taking. This professor would give exams and then give the students a score, but would not give the exams back or tell students where they lost points. I talked to that professor later, and she indicated that she did not give exams back because she reused questions.
A sad state of affairs, where student learning takes a back seat to faculty member's conveniences and laziness.
