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 management. The purpose of the module is to prepare teachers to deal with students who are using chemicals--alcohol and other drugs--to an extent that their performance in the classroom and laboratory is adversely affected. The module also helps the teacher to define his/her feelings about chemical use and gives skill in using prevention and intervention techniques and in providing support, reinforcement, and alternatives to students who are struggling to recover from chemical use. Introductory material provides terminal and enabling objectives, a list of resources, and general information. The main portion of the module includes four learning experiences based on the enabling objectives. Each learning experience presents activities with information sheets, samples, worksheets, checklists, case studies, and self-checks. Optional activities are provided. Completion of these four learning experiences should lead to achievement of the terminal objective through the fifth and final learning experience that provides for a teacher performance assessment by a resource person. An assessment form is included. (YLB)
