Abstract:
The purpose of this research was to develop an e-Learning lessons on basic indoor electrical for level 1 indoor electricians, to determine its quality and efficiency, compare student achievements between a pre-test and post-test, and measure students satisfaction with the program. The population for this study was 30 third-year students from the Department of Electrical Power, Minburi Technical College. The tools for data collection were seven e-Learning Lessons, a quality evaluation form, and an achievement tests. The statistics utilized for data analysis were percentage, mean, standard deviation, and t-test. It was found that the quality of e-Learning Lesson was at the great level (x̄ = 4.55, S.D. = 0.43) while the media production technique was at a good level (x̄ = 4.40, S.D. = 0.14). The efficiency of the e-Learning lessons or the pass rate was 86.67%, in accordance with the specified hypothesis ≥ 80%. When the pre-¬test and post-test were compared, it was found that the average of post-test scores (x̄ = 71.77, S.D. = 3.53) was statistically higher than the pre-test ones (x̄ = 46.97, S.D. = 3.42) at the 0.05 level, student satisfaction was at the more level (x̄ = 4.30, S.D. =0.57)
