Teaching at your alma mater can be difficult. Former professors become your colleagues, and you have to overcome the reluctance to challenge or contradict your mentors. You also have to confront suspicions about academic “incest” from outsiders.
For me, the experience has been mostly positive. I chose Cumberland as my undergraduate institution because of the small classes and the old buildings. Like me, many of our students are drawn to former. (There are no data for the latter, as far as I know.) It’s good to be able to pass students in the hallway, on campus, or in town, and be able to recognize faces and (usually) remember names. While a small campus community can be like a small town when it comes to gossip, I think the closeness of the community outweighs that factor. You are also able to tell students that you have been exactly where they have been, sometimes literally in the same seat.
If I were brave, I would post my freshman year photo, suitcase and all. Notice that I didn’t, but I may or may not be on this page.
