DEVELOPMENT OF INSTRUCTIONAL MEDIA AUGMENTED REALITY TECHNOLOGY ON WORKING DUTY OF SMALL GASOLINE ENGINE FOR VOCATIONAL CERTIFICATE LEVEL STUDENTS IN VEHICLE TECHNOLOGY DIVISION

This research were to develop and make the efficiency assessment of Augmented Reality (AR) technology media in small gasoline engine job, focusing on the functions of small gasoline engine parts and to make the comparative study of the Student’s Learning achievement who taught using AR technology media in small gasoline engine job with a criterion group, which consisted of 30 vocational certificate level students. They were selected by cluster random sampling. The instruments used in this research were: 1) AR technology media 2) A learning achievement test in a multiple-choice format with four choices. The index of item-objective congruence (IOC) for each item ranged from 0.60 to 1.00, a difficulty index ranging between 0.40 to 0.67, a discrimination value ranging between 0.20 to 0.87, and a reliability of 0.86. Commonly used statistical analyses, standard deviation, and t-test statistics. The results of the search indicate that: 1) AR technology media in small gasoline engine, focusing on the functions of small gasoline engine parts for vocational certificate students in the Automotive Mechanics Department was a high level of suitability and an efficiency of 81.67/83.89 2) Student’s Learning achievement who taught using AR technology was statistically of 80/80 higher than the criterion at .05 level of significance.
