This study examined the challenges encountered by student teachers during their practicum experience. They coded the data independently and found three major themes: 1. Student teaching is a very stressful period for preservice teachers, due to the workload and to student behavior issues; 2.The most positive aspect of student teaching is the formation of positive relationships with the mentor teacher and with students. 3. If given a chance to do so, few student teachers would change their experiences and are optimistic about their futures.
