THE EFFECTIVENESS OF ONLINE COURSE THE OPERATING AMPLIFIER AND FILTER CIRCUIT, OP-AMP AND LINEAR IC

Abstract

This research was to create online educational media that included a teaching video with online course on Operating Amplifiers and Filter Circuit, Op-Amp and Linear IC. The experts assessed the quality.The students’ learning achievement was compared before and after learning, and the student’s satisfaction with online course was surveyed. The sample group used in this research were 25 first-year students in group 2 from the Electronics Department at Nakhonsawan Technical College which were selected by purposive random sampling. The instrument used in the research was the online course on Operating Amplifiers and Filter Circuit, Op-Amp and Linear IC, and a pre- and post-learning achievement test. The statistics used to analyze the data were efficiency (E₁/E₂), mean (), standard deviation (SD), and t-test. The results showed that the content quality of the online course on Operating Amplifiers and Filter Circuit, Op-Amp and Linear IC was at the highest level ( = 4.56, SD = 0.51) and the quality of media production technique was at the highest level ( = 4.67, SD = 0.41). The effectiveness of the online course on Operating Amplifiers and Filter Circuit, Op-Amp and Linear IC met the specified criteria. The sample group met the E₁/E₂ criteria, scoring at least 80/80. The scores during learning and the assessment after learning from 23 of 25 students were 90.90/89.60. The learning achievement of the students who studied the online course on Operating Amplifiers and Filter Circuit, Op-Amp and Linear IC, after learning ( = 35.84, SD = 2.78) was higher than before ( = 12.76, SD = 3.83) with statistical significance 0.05. The students’ satisfaction with the online course was at the highest level ( = 4.75, SD = 0.42).
