The Development of Learning Achievement in Technology Subject (Design and Technology) of Grade 9 Students at Thamuangratbamrung School Using Digital Lessons Integrated with Discussion-based Learning

Abstract

The purposes of this research were to: 1) develop digital lessons in Technology Subject (Design and Technology); 2) evaluate the quality of content and technical design of the digital lessons; 3) determine the efficiency of the digital lessons integrated with discussion-based learning; 4) compare students' learning achievement before and after learning through these digital lessons integrated with discussion-based; and 5) study students’ satisfaction learning with digital lessons integrated with discussion-based learning. The sample group used in the research consisted of 27 Grade 9/6 students, derived by cluster sampling. The research instruments included lesson plans, digital lessons, learning achievement tests, content quality assessment form, lesson production quality assessment form, and a students’ satisfaction questionnaire. Data were analyzed using percentage, mean, standard deviation, and dependent t-test. The research results revealed that: 1) the digital lessons in Technology Subject (Design and Technology) consisted of 3 units: 1.1) fifth-generation wireless networks (5G); 1.2) electric vehicles; and 1.3) logistics management; 2) the content quality and the technical quality of the digital lessons production was at a good level (x ̅ = 4.44, S.D. = 0.40); 3) the efficiency of digital lessons integrated with discussion-based learning was 88.15/73.95; 4) the students’ learning achievement after learning was significantly higher than before learning, with a significance level of .05; and 5) overall, the students satisfaction with learning through the digital lessons integrated with discussion-based learning was at the highest level (x ̅ = 4.52, S.D. = 0.15).
