Abstract:
Objective of this research was to 1) to development of practice evaluation form small diesel engine service for vocational training school and 2) to study the effect of using the practice evaluation form. The research population was students at the vocational training school, automotive mechanics. The sample group was of 10 Phra Dabos vocational students, automotive mechanics by using a specific sample sampling method. The research procedures were as follows: 1) determine behaviour objectives by job analysis methods, 2) analysis behaviour objectives to set the evaluation point, 3) development of practice evaluation form, 4) analysis the interobserver reliability, 5) evaluate the practice results with the sample group and 6) study the satisfaction of teachers and students. The research instruments included 1) the practice evaluation form, and 2) the satisfaction of teachers and students form on the evaluation process. The data were analysed using statistics 1) percent, 2) mean, 3) standard deviation, 4) index of consistency, 5) rational evaluation coefficient, 6) interobserver reliability and 7) Shapiro -Wilk test. The results showed that 1) the practice evaluation form consisted of 8 were reliability between .845 - .927, 2) the practice evaluation results were averaged 81.00%, 3) the satisfaction of the teachers with the evaluation process was in the very good level, the mean 4.62 and 4) the satisfaction of the samples with the evaluation process was in the good level, the mean 4.38.
