This report describes the fifth in a series of studies assessing micro-teaching and video recording in vocational and technical education. The 48 participants were randomly assigned to eight treatment groups which consisted of combinations of the two levels of the three major variables: (1) video feedback or no feedback, (2) teaching four 5-minute lessons or two 10-minute lessons, and (3) teaching high school students or teaching peers. The focus was on the effect of each of the variables on participants' teaching skills, the effect teaching high school students has on self-confidence in ability to teach, and the participants' attitudes and opinions regarding their experiences. Data were analyzed by a "t" test and analysis of variance of the mean percentage of gain scores. No significant differences were found for or against any of the procedures tested except in the "t" test of gain in teaching skills; however, the attitudes and opinions of the participants reflected strong support for the use of video recording in preservice and inservice trade and industrial teacher education.
