The development of performance test in arc welding for vocational certificate students

Abstract

The purpose of this study was to develop the performance test in quality arc welding for vocational certificate students which was divided into 2 sections. The first section was creating performance test in arc welding for vocational certificate students. The samples were 5 teachers who had experiences in teaching Basic Farm Mechanics more than 5 years or teachers who had ability in Education Assessment. The instrument used was performance test in arc welding which consisted of 2 parts. The first part was the test of performing process and the second part was observation check sheet. The data was analyzed in term of content validity. The finding was performance test had content validity by using Index of item – Objective Congruency ( IOC ) at 0.80-1.00.

     The second part was developing the performance test in welding for vocational certificate students. The samples were 30, the first year vocational certificate students enrolled in the first semester of the academic year 2013 and 2 teachers who had experiences in teaching Basic Farm Mechanics more than 5 years. The instrument used was performance test in arc welding which consisted of 2 parts. The first part was 54 items observation check sheet to evaluate the process of performing. The second part was 6 items of observation check sheet to evaluate the outcome of performing. The data was analyzed by using means, standard deviation, Pearson‘s coefficient correlation and t-test for independent samples. The finding was found that the performance test in arc welding for vocational certificate students had classify validity of performing process test at 3.643 and performing outcome at 3.750 and the validity from 2 teachers was at .952 and .885 by using Pearson’s coefficient correlation.
