I've taught classes as small as a single student. I actually prefer small class sizes because of the personalized instruction. One of the major challenges is that there is no way to curve on exams and tests (in any real sense), so the student basically works against their own performance in that scenario.
Other than that, attendance can sometimes be an issue (it's easy for half...or all of the class to miss a session--in which case I often either repeat the lecture, or make it available via YouTube.
Video podcasting has proven a VERY effective tool for many of the obstacles associated with problem attendance and the necessity of covering too much material in too little time.
I welcome your feedback!
