The development of Computer Assisted Instruction on Introduction to Computer Networks For students of the 3nd year of vocational certificate in the field of business computer

This research has the following objectives: 1) to design and develop computer-assisted lessons for the basic computer network course, 2) to determine the learning efficiency of students using computer-assisted lessons for the basic computer network course, 3) to assess pre- and post-learning outcomes, and 4) to evaluate student satisfaction with the computer-assisted lessons. The development of these computer-assisted lessons follows the principles of the ADDIE Model, which aligns with the instructional design and development process. The sample group consists of 40 third-year vocational certificate students from Chitranon Vocational College of Technology. The research tools used include: 1) computer-assisted lessons for the basic computer network course for the third-year vocational certificate students, 2) performance assessment tests, and 3) satisfaction surveys for students regarding the computer-assisted lessons. The research findings indicate that the quality of computer-assisted lessons is good, with an average score of 4.02 The effectiveness of the computer-assisted lessons is 92.19/93.63, which exceeds the set standard of 80/80. When analyzing the exam scores before and after learning, it was found that learners had a significantly higher learning outcome after studying compared to before studying at a statistically significant level of 0.05, student satisfaction with the computer-assisted lessons is high, with an average score of 4.28The computer-assisted instructional lesson created is effectively utilized as a learning tool in the Basic Computer Network course for the third year of the professional certificate program.
