This module, one in a series of performance-based teacher educational learning packages, focuses on skills that vocational educators and other occupational trainers need to create learning environments that are accessible, accommodating, and equitable in meeting instructional needs of exceptional students. The purpose of the module is to give educators skill in identifying those students who have special instructional needs and in diagnosing what those needs are. Introductory material provides terminal and enabling objectives, prerequisites, necessary resources, terminology, and general information. The main portion of the guide includes four learning experiences based on the enabling objectives. Each of the first three learning experiences includes educational activities with information sheets, case studies, and self evaluation forms. Optional activities are also provided. Completion of the first three study sections should lead to achievement of the terminal objective administered in the fourth and final learning experience that includes a teacher-performance assessment form.
