Subjective confidence for solving classroom problems while instructing students in appropriate academic material is crucial for effective teaching. One way to develop problem solving confidence may result from the semester most education majors spend in the classroom as student teachers. The problem solving inventory (PSI) was given to university education majors in a pretest-posttest format where they responded before and after the completion of student teaching. Analyses indicated the student teachers thought they had more confidence for problem solving during the posttest condition as indicated by significance on the PSI's subscales. The semester spent in the classroom as a student teacher plays an essential role in the development of the necessary subjective confidence for solving classroom problems.
