The Development of Digital Course with Technology Based Learning to Improve the Practical Skills in the Computer Science For Students in Secondary School

Abstract

The objectives of this research are 1) to find the efficiency of digital course with technology-based learning management to improve practical skills in computer science for secondary students. 2) to compare the post-learning achievement of computer science between the experimental group and the control group, and 3) to compare the post-learning of computer science practical skills between the experimental group and the control group. The population was Mathayomsuksa 5 students at Ladplakhao Pittayakom School, the Secondary Education Service Area Office Bangkok, 2 that consist of 8 classrooms, with a total of 225 students. The sample group was Mathayomsuksa 5 students at Ladplakhao Pittayakom School, the Secondary Education Service Area Office Bangkok 2 in the 2nd semester of the academic year 2022. That consisted of 2 classrooms with a total number of 70 students. There were 35 students in Grade 5/1 assigned to be a control group and 35 students in Grade 5/2 assigned to be an experimental group by cluster random sampling including mixed abilities and not different learning achievements. The research instruments were 1) the course plan for the graphic design course with an image edition program; 2) digital course with technology-based learning to improve practical skills in computer science; 3) a computer science learning achievement test; and 4) computer science practical skills test. The data were analyzed by mean, standard deviation, and t-test statistics. The results found that 1) The efficiency of digital course with technology-based learning to improve practical skills in computer science was at 80.60/86.96 which was higher than the criterion. 2) The post-test learning achievement of digital course with technology-based learning to improve practical skills in computer science of the experimental group was higher than the control group at the statistic level of .05. and 3) The post-test learning of computer science practical skill scores of the experimental group were higher than the control group at the statistic level of .05
