Abstract

The primary purposes of this study were: 1) to gather historical information about the development of visual aids in extension work in the United States: 2) to review the generally accepted theories of visual communication, and 3) to study and summarize the research done on the effectiveness of various individual visual aids. A secondary purpose was to utilize these findings as a basis for formulating a working plan for the development of a visual aids section at the Agricultural College and Research Institute, at Coimbatore, Madras State, India. By such study and adaptation, it is hoped that extension teaching may be made richer and more meaningful both to extension workers as well as farmers.
