This paper follows a student teacher through a typical day in her high school student teaching placement, beginning with her pre-dawn departure for school, and moving from her preparations for class to her classes, which begin at 7:15 a.m. (homeroom, several periods of biology, lunch, planning, more biology, and biochemistry). She focuses on her relationship with the cooperating teacher and with the students in each class, discussing how she handles classroom problems as they arise. She notes differences in students' classroom behaviors throughout the day and discusses the difficulty of teaching biochemistry, which is a course she has never taken. After school, she still has grading and planning, so she typically stays 2 more hours. Often, she takes a nap, then wakes up later to plan some more. Some days, she cannot nap because she has after-school events and meetings to attend. Interview questions are appended. (SM)
