ABSTRACT During their practicum, student teachers seem to move through three phases of development, each requiring different types of training and guidance from the cooperating teacher and supervisor. In phase one, “Mastery of Basic Instructional Techniques,” student teachers feel inadequate about the mechanics of planning and presenting different kinds of lessons. Performance criteria for specific lessons will guide them in observing their cooperating teachers, in planning such lessons, and in classroom microteaching. In phase two, “Developing Sensitivity to Pupil-Teacher Interactions,” when student teachers are concerned about teacher and student activity during an entire class period, they may use different instruments to analyze the dynamics, behaviors, interactions, and learning that occurred. Finally, in phase three, “Overall Analysis and Evaluations of Teaching Effectivenes,” gathering data on teacher/student activities and interactions will aid student teachers in looking for recurring patterns of behavior that need changing to improve learning and those behaviors that were effective. All the activities and instruments presented are useful for student teachers in their practicum training and for experienced teachers in self-evaluation.
