In developing a program for the professional development of supervisors, cooperating teachers, and student teachers, consideration was given to traditional observation methods. These methods focus upon observing: (1) the organization of independent study; (2) activities designed to enhance learning as it relates to goals of the classroom; (3) small groups working together on common projects; and (4) laboratory procedures in which students learn to manipulate skills involving specialized equipment or facilities. Rating scales have been devised and are included in this report for observers responsible for evaluating the professional development of program participants. Focusing on independent study, learning stations, small group instruction, and laboratory situations, these rating scales provide a framework for evaluating the planning, implementing, and effectiveness of each of these program phases.
