The Development of Online Lessons with Learning Together Techniques on Computational Science for Grade 9 Students at Ban Nong Khet School

Abstract

The purposes of the research were as follow: 1) To develop the online lessons with Learning Together techniques on computational science for Grade 9 students at ban nong khet school, 2) to find the efficiency of the developed online lessons, 3) to compare the learning achievement of the students before and after learning with the developed online lessons and, 4) to study the students’ satisfaction towards the developed online lessons with Learning Together techniques. The sample group used in this research were 20 students in Grade 9 Selected with Cluster Sampling. The tools used in the research were management plans, the developed online lessons with Learning Together techniques on computational science for Grade 9 students, the media’s evaluation forms on contents and techniques, the pre-tests and post-tests, and the students’ satisfaction questionnaires. The statistics used in the research were percentage, mean, standard deviation, and t-test. The research findings were as follow: 1) The developed online lessons evaluated by 3 experts on the contents and techniques had the overall score at the highest level (𝑥̅ = 4.58, S.D. = 0.59), 2) the efficiency of the developed online lessons with Learning Together techniques was at the level of 83.19/81.52 which was higher than the set criteria of 80/80, 3) the students’ learning achievements after learning were higher than before learning at .05 level, and 4) the students’ overall satisfaction towards learning with the developed online lessons was at a high level (𝑥̅ = 4.30, S.D.= 0.44).
