Advantages of using the microcomputer as an interactive electronic blackboard are discussed, and programs and programming techniques are described to illustrate the construction, design, storage, and modification of colorful and animated graphic displays. The methods described are based on use of an Atari 800 microcomputer but could be used on other systems. Suggestions are made for the use of display lists, short programs dedicated to the video display, which specify where to find screen data and which mode and what special display options, if any, are to be used. Another technique explained is page flipping, a process which permits a number of different screens or pages to be drawn by a single computer program. The program is able to store the display list instruction set for each of the previous screens and rapidly recall them if desired. Descriptions of programs that use these methods include a summary of the main features of 11 specific programs developed by the author. Examples are given of programs for physics simulations, graphing and plotting, numerical problem solving, and the production, saving, and modification of diagrams. Sample uses are explained to show how the program might be employed by an instructor. A summary and four references are included. (LMM)
