DEVELOPMENT OF AN AUTOMOTIVE PAINTING SKILL TRAINING PACKAGES FOR VOCATIONAL CERTIFICATE STUDENTS IN THE INDUSTRIAL SUBJECT TYPT

Abstract

Abstract

The objective of this research article is to develop and determine the effectiveness of a skill training kit in automotive painting, and to compare the learning achievement of students who studied using the training kit with a predetermined criterion. This research is qualitative in nature. The sample consisted of one class of 26 third-year vocational certificate students, selected through cluster sampling.The instruments used for data collection included: 1. A problem record form and instructional problem-solving guide, 2. A skill training kit, 3. An appropriateness evaluation form with content validity ranging from 0.60 to 1.00, 4. A performance assessment form with content validity ranging from 0.60 to 1.00, and inter-rater reliability of 0.70. Data were analyzed using content analysis, mean, standard deviation, and t-test statistics.

The research findings revealed that the developed skill training kit covered practical knowledge, including the selection of tools and equipment, surface preparation, putty application, sanding, paint spraying, color mixing based on formulas, and actual painting. The training kit was designed as a series of well-structured hands-on activities, accompanied by exercises and a learner’s manual that allows for self-directed learning.The researcher was therefore motivated to develop this skill training kit for instructional purposes. The overall appropriateness of the training kit was rated at the highest level (mean = 4.59, S.D. = 0.13). The effectiveness of the skill training kit for vocational certificate students in the industrial field exceeded the specified standard of 75/75. Moreover, the comparison of students’ practical performance after using the training kit showed results significantly higher than the 75% threshold, at a statistical significance level of .05.
