I teach a lecture course as an adjunt. At many universities, the majority of classes (in all disciplines) are taught by adjuncts and not by people who are employed either full time OR part time. Adjuncts are hired and usually paid per course. I read recently that the typical rate for an adjunt instructor teaching a 3-hour (per week) lecture course for a full semester ranges anywhere from $2500 to $7500.
I make $4600 for my course. As I have taught the same course for about 5 years now, I don't have to spend a lot of time on class preparation -- just a couple of hours to tweak and update things for each lecture. The big variable is grading, coaching, and counseling. Some years, the number of students taking the course is small and I don't have to spend a lot of time grading papers, meeting with students, etc. But other years, I have had large classes that took so much time that I was grossly underpaid.
I've had friends work as adjuncts for clinical courses and they have a similar deal. They get paid a flat rate (higher than the one I get for my lecture course) -- and it's up to them to decide how much time they spend preparing, grading, coaching, and counseling for the money.
People with an actual ongoing "part time" contract may have different arrangements than those typical for adjuncts. Are you classified as an adjunct or as "part time" -- with ongoing responsibilities in addition to just teaching?
