My name is Derek Bruff, and I am a preceptor in mathematics at Harvard University. There are several preceptors here, and we are primarily responsible for making sure that the service courses (calculus and linear algebra) are well taught. The courses are taught in small sections (15-40 students, depending on the course), but the students in each course follow the same syllabus, turn in the same homework problems, and take common exams. The sections are taught primarily by preceptors and other junior faculty members and by graduate students. Each course has a course head, typically a preceptor, but occasionally another faculty member, who coordinates the course. As a preceptor, I teach sections and occasionally act as course head. Since most sections are taught by graduate students and junior faculty, the preceptors are also responsible for preparing and supporting these teachers. We organize an apprentice program for first-year graduate students who are not yet teaching. We also provide support for those who are currently teaching through pre-semester orientations, term-time teaching seminars, observations, and consultations. We also train and supervise undergraduate course assistants. Each calculus section is assigned one CA who grades homework, runs problem sessions, and works in the tutoring center. In the past, this training has taken the form of a pre-semester orientation. We are now consider term-time teaching seminars as well. Enough about me for now! I'm excited to hear about you!
