The purpose of this training module is to introduce science teachers at the secondary level to effective applications of microcomputers for instruction and to provide information on the current state of science-related microcomputer courseware. Designed to provide for 12 presentation hours, the module is divided into seven sessions: (1) Realities and Aspirations; (2) Computer-Assisted Instruction and Computer-Managed Instruction (CAI and CMI); (3) Simulations, Tutorials, and the Use of Graphics; (4) Calculations, Analysis, and Workup of Data; (5) Collections of Experimental Data; (6) Problem Solving Strategies and Inquiry; and (7) Conclusions and Evaluation. The four sections of this document provide: (1) a rationale for the subject matter, an overview of the entire module, and suggestions for presentation; (2) notes for the presenter, including step-by-step procedures for organizing major concepts into sequential sections with overview, learner outcomes, lists of needed materials and equipment, and time requirements for each of the seven sessions; (3) materials for participants, including all of the handouts needed to present the entire training module; (4) instructional materials, including a short description of a videotape intended for use with the sixth session, and transparency masters and diskettes needed for presenting the module. The appendixes include a list of science courseware, useful addresses and sources of assistance, a certificate to be handed out to participants, and a listing of all of the programs on each of the diskettes intended for use with this module.
