AN INVESTIGATION OF THE USE OF A PROTOTYPE DEVICE FOR CLASS SCHEDULING WAS MADE. THE BEEKLEY INSITE DEVICE THAT WAS STUDIED USES THE "PEEK-A-BOO" PRINCIPLE OF MATCHING COMPUTER TAPES. A TEST GROUP OF 149 GRADUATE STUDENTS WAS USED. THEIR DESIRED SCHEDULES WERE MATCHED AUTOMATICALLY AGAINST A PROPOSED MASTER SCHEDULE TO EVALUATE THE USEFULNESS OF THE DEVICE. THE STUDY SOUGHT MEANS TO (1) PROVIDE STUDENTS, DURING REGISTRATION, WITH ALL FUTURE TERM SCHEDULES THAT MIGHT BE OFFERED, (2) PROVIDE THE ADMINISTRATION WITH CURRENT AND FUTURE TERM SCHEDULES THAT COULD NOT BE PROVIDED BY ADJUSTMENT OF MASTER SCHEDULES, AND (3) IDENTIFY SCHEDULING VARIABLES TO BE CONSIDERED IN RESOLVING SCHEDULING PROBLEMS. THE TEST RESULTS INDICATED (1) THE "PEEK-A-BOO" APPROACH TO SCHEDULING COULD BE USEFUL TO BOTH THE STUDENTS AND THE ADMINISTRATION, (2) ALTHOUGH THE DEVICE TESTED HAD MANY DESIRABLE CHARACTERISTICS, FURTHER DEVELOPMENT WAS NEEDED TO PROVIDE REAL-TIME OPERATION OF SUCH A SYSTEM, AND (3) A MACHINE-PROCESSIBLE RECORD CREATED BY THE STUDENT DURING REGISTRATION MIGHT SERVE AS A STARTING POINT FOR INVOICING, GRADE REPORTING, AND SIMILAR FUNCTIONS.
