This module, one in a series of performance-based teacher education learning packages, focuses on a specific skill that vocational educators need to be successful in the area of instructional execution. The purpose of the module is to help the vocational-technical teacher develop competency in the technique of demonstrating a concept or principle. Introductory material provides terminal and enabling objectives, prerequisites, a list of resources, and general information. The main portion of the module includes three learning experiences based on the enabling objectives. Each learning experience presents learning activities with information sheets; samples; self checks and model answers to self checks; case scripts, critique forms, and model critique forms; and/or checklists. Optional activities are provided. Completion of these three learning experiences should lead to achievement of the terminal objective through the fourth and final learning experience that provides for a teacher performance assessment by a resource person. An assessment form is included. (YLB)
