Focuses are revising existing performance objectives or writing one's own and establishing the validity of both terminal and enabling performance objectives. Contents include three learning experiences based on three enabling objectives that provide background information, practice experiences, or a combination. Completion of these experiences should lead to achievement of the terminal objective in the fourth and final learning experience with teacher performance assessment form. Each learning experience includes a learning activity (activities) with information sheets, case studies, and self-checks with model answer (as feedback). Optional activities may also be provided.
