This courseware evaluation rates the Interior Design Simulator program developed by Orange Juice Software Systems. (This program--not contained in this document--allows the user to design a room of any shape with maximum dimensions of 14 x 26 feet.) Part A describes the program in terms of subject area (furniture arrangement) and hardware requirements (Apple II series), indicates its suitability for use as a tutorial or simulation for grades 9-12, and gives a time estimate (30-45 minutes). Availability information includes cost ($50.00), preview policy (30 days), 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. The program was rated yes for subject matter and somewhat for technical presentation, student and program interaction, student evaluation, documentation, and work behaviors. Strengths include good simulation of furniture arranging, but reviewers suggested a need for more rules and more application questions. The program is recommended for a class in basic furniture arranging to give students practice. (SK)
