A study was made to explore how a time sharing computer system can help the coach of high school sports. A structural analysis determined that the computer's capability to process information helps the coach: (1) store large quantities of information; (2) perform numerous operations in a very short amount of time; (3) provides consistent accuracy while also providing versatility. Next, a computer model encompassing thirteen sports was grouped according to each sport's individual needs. This grouping enabled a coach to develop general types of computer programs for "common" activities. Here, the computer was used as a problem solving tool to assist the coach in the analysis of activities and the data which they generate. The programs need to be sufficiently general to suit a variety of coaches and activities, but have built in definable parameters to meet specific needs. Five areas of secondary athletic computer application areas have been: simulations, scheduling, scoring, statistics, and scouting. As a result, a great deal of a coach's time has been saved and a more meaningful type of information has been obtained from computer usage. (WCM)
