A study determined effective inservice education methods to reduce the apprehension of experienced vocational education teachers regarding instruction of handicapped students. In order to guide the study, three null hypotheses were generated and tested. A three-group, randomized, pre- and post-test experimental design was utilized. Thirty teachers of vocational agribusiness in Alabama, who were attending a workshop for cooperating teachers, were randomly assigned treatments which consisted of a videotaped presentation, a lecture (control), and a self-paced individualized packet. The Attitudes Toward Disabled Persons (ATDP) instrument was utilized to collect data. Descriptive and inferential statistics utilized to analyze the data included percentages, means, frequencies, correlated T-tests, Chi Square, and analysis of variance. All three null hypotheses were rejected at the .05 level of confidence: Voc-Ag teachers were moderately positive in attitudes toward the disabled; there were changes in attitudes after inservice treatments as measured by the ATDP; and the videotape presentation was most effective. Lecture was next in effectiveness, and the self-study was least effective in changing attitudes of teachers toward the disabled. Seven recommendations were made based on the findings of the study.
