This courseware evaluation rates the Reading Vernier Calipers program developed by EMC Publishing Company. (The program--not contained in this document--uses high resolution graphics to illustrate the micrometer and describe its components, functions, and practical applications.) Part A describes the program in terms of subject area (technical drawing, construction, measurement) and equipment requirements (Apple II and a Vernier Caliper), indicates its suitability for use as drill or tutorial in grades 9-12, and gives a time estimate (45 minutes). Availability information includes contact address. Part B contains the evaluation criteria in eight categories; reviewer ratings appear as yes, somewhat, no, and not applicable, with explanatory comments. Part C summarizes the evaluation. This program received yes ratings for subject matter, technical presentation, student and program interaction, and documentation; somewhat ratings were given for documentation and student evaluation. Strengths were good pace and effective use of graphics; reviewers noted that it does not provide the correct answer if students answer incorrectly. The program is recommended as a stand-alone or reinforcement tool. (SK)
