This thesis has explored the procedure utilized in the writing, testing, and revising of a programed text on animal development. First, this study has discussed the need for self-instructional material in the schools of this country. Next, the study has provided evidence which shows the need for programed material on animal development for general biology classes at Ball State University.This study has then described a procedure for organizing and writing the programed material. Following this, the thesis has outlined a methodology for testing the program, treating the data, and revising the program. Finally, the study has included a discussion of the specific revisions in the program based on the test results.Included in the appendix of this thesis is a final draft of the manuscript of the program.

The present investigation concerned itself with the efficiency of the audio-tutorial method of teaching biology as compared with the more conventional method usually seen in college biology, which involves the use of lectures and laboratory periods.

This creative project contains step by step procedures for the set up and operation of hardware as well as software for an automated four projector system designed for use in the Electronic Response Laboratory in the Department of Biology at Ball State University. The main divisions of this project were:1) Set up of four projectors including location, position and adjustments.2) Linkage of projectors to dissolve controls.3) Synchronization procedures for linkage of projector system with a tape recorder through the use of actuator cables and a sound synchronizer.4) Impulse recording and final operational procedures. 5) A brief description of software production.Ball State UniversityMuncie, IN 47306
