This courseware evaluation rates the Orthographic Projection program developed by Hobar Publications. (The program--not contained in this document--uses computer graphics to present abstract visual concepts such as points, lines, and planes.) Part A describes the program in terms of subject area and hardware requirements (Apple II), indicates its suitability for use as drill or tutorial in grades 9-12, and gives a time estimate (20 minutes per project for 7 projects). Accompanying materials include student and teacher manuals. Availability information includes backup policy ($7.50 for replacement disk) and 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. Yes ratings were given for subject matter and technical presentation; somewhat for student interaction and documentation; the other categories were not applicable. Reviewers found the program to be well done and a concise presentation. Weaknesses were some directions, overlapping of points or lines, and difficulty moving from one drawing to the next. The program is recommended for group instruction. (SK)
