DEVELOPMENT OF A LEARNING ACHIEVEMENT TEST IN COMPUTING AND INFORMATION FOR CAREER COURSE FOR VOCATIONAL CERTIFICATE STUDENTS

Abstract

The objectives of this research were: 1) to examine the quality of lesson plans for the Computing and Information for Career Course for vocational certificate students; and 2) to develop a learning achievement test. The sample, obtained through stratified random sampling, consisted of 30 third–year vocational certificate students at Det Udom Technical College. Statistics for data analysis included mean, standard deviation, item–objective congruence index, item difficulty, discriminative power, and Cronbach's alpha reliability coefficient.

The results revealed that: 1) the overall quality of the developed lesson plans was at the highest level with a mean score of 4.86 and a standard deviation of 0.16; 2) the developed learning achievement test items comprised 48 items, with item–objective congruence ranging from 0.60 to 1.00, item difficulties ranging from 0.30 to 0.83, the discriminative power ranging from 0.35 to 0.77, and the reliability of 0.94.
