I may not agree with all of the rules or the reasons, but the rules aren't just arbitrary. And, in fact, many of the reasons make sense as a framework for teaching and learning. I think instructors serve their students better if they make an effort to understand all the rules, explain them as best they can to students, help students cope with them, or work to change them if they think that's necessary. Some of the rules that affect us and our students don't relate directly teaching and learning, but because they affect our students, and occupy their time and attention, we should help them understand and comply with them. New faculty members do have an orientation to the university.
Some colleges have orientation, and some departments provide some training.
The best way to get to know the policies is to read the Undergraduate Bulletin which is readily available in print or easily accessible over Temple's web page. This falls into the category of things to which we should pay attention because they affect our students. Students need to have an official record, have to register, pay, etc. If these requirements are not settled, then students have to spend time on these issues, and worry about them instead of paying attention in class, doing their readings, etc. Instructors tend to know about and use the policies and procedures that serve their purposes and ignore the rest.
