Under faculty supervision, student-teachers will prepare and conduct scheduled weekly extra sessions for calculus, for smaller, assigned groups of students. For these sessions they will prepare presentations, assign and grade homework, and answer questions on the course material and on the homework. They will be available to their students outside of class, attend and assist at calculus lectures (3 hours a week), and visit and evaluate each other's sessions. There is a busy weekly meeting, for an hour or two, including organizational matters, deeper study of the calculus, and practical teaching skills. There will be assigned readings, discussion, drills, and weekly homework or papers. The student-teachers will participate in the design and review of exams, weighing the importance and difficulty of questions, and observing the kinds of mistakes the students make. Format: lecture/seminar/teaching. Evaluation will be based on the overall teaching activity, responsibility, participation in the seminar and other meetings, homework and papers. Prerequisites: permission of instructor early in the previous Fall. Enrollment limit: 5 (expected: 4).
