| Abstract: | The purpose of this study was to develop programmed instruction booklets and measure their effectiveness for self-instruction in descriptive geometry at the college level. More specifically, this problem involved: (1) developing programmed instruction booklets, (2) developing measuring instruments, (3) conducting the experiment for the purpose of collecting pertinent data, and (4) interpreting the collected data. Programmed booklets and testing instruments were devised for the instruction of three units selected at random from the descriptive geometry course outline. These materials were subjected to evaluation by a qualified jury and revised as recommended. A pilot study was conducted utilizing the materials in a class of twenty students. With the knowledge gained in the pilot study land suggestions and recommendations of the participating students taken into consideration, the research materials were revised and developed in final form. ... |
