Remembering student names does not come naturally to me. I found early on that if I don't make an extra effort here, it won't happen. Oh, I'll pick up a few names, mostly of those who answer questions or do excellent work. But I won't pick up the names of the quieter students, which is really bad because they may need more attention and it's going to feel really awkward several weeks into the course if I go to help them and can't remember their name! So I usually make a copy of the roster and focus after the first session for just a few minutes, putting faces to names in my head. It won't "take" for all of them right away, but after a couple of weeks I've usually got it down (and I think a couple of weeks in a ten-week course is reasonable). Also, when I do forget a name, I try to put a "happy face" on it, being humorous but not (of course) insulting a funny-sounding name or anything like that. I usually just try to laugh at myself a bit and let the students know it's okay to laugh at me too. It's not like we're going to hide the fact that it's hard to remember a lot of names -- they know that can be tough. But they appreciate the effort, even if it's not 100% successful. They can see that I'm remembering other students' names even if I happened to forget theirs, and usually if something like that happens it sets it in memory anyway so I won't forget that student's name again.
