To test the feasibility of teaching a methods course totally or partially by telelecture, a control group of 15 was taught by traditional lecture-discussion, an experimental group of 15 was taught with 50 percent traditional and 50 percent telelecture, and another experimental group of 25 was taught only by telelecture. Each group consisted of inservice vocational-technical teachers enrolled in a one-semester course on the principles of teaching industrial subjects. All students were given an Otis Employment Test and a pretest of course content to measure general ability and initial status, and written and oral evaluation procedures were conducted throughout the course. Data were analyzed by one-way analysis of variance, chi-square, coefficient of correlation, and concordance W. Conclusions indicated: (1) A professional course may be presented with equivalent results either by traditional or telelecture methods, (2) Student attitudes were not adversely affected by either course content or method of presentation, and (3) Telelecture was more economical in costs and in travel time. This Ed.D. thesis was submitted to the University of Missouri. (GR)
