THE DEVELOPMENT OF ONLINE LESSONS ON THE INTERNET ACCORDING TO THE INQUIRY-BASED LEARNING MODEL FOR GRADE 8

This research aimed to develop and evaluate the quality of an online lesson on the topic of the Internet, based on the 5E inquiry-based learning model. The study compared students' learning achievement before and after using the lesson, examined learning retention, and explored students' satisfaction with the online lesson. The lesson was developed using the ADDIE model, which consists of five steps: Analysis, Design, Development, Implementation, and Evaluation. The online lesson on the Internet followed the inquiry-based learning model, comprising the steps of: Engage, Explore, Explain, Elaborate, and Evaluate. The lesson was presented through various media formats, including text, still images, animations, videos, and narrated audio. The sample group consisted of 30 Grade 8 students from one class, selected through clusters random sampling from an initial pool of three students. The research instruments included the online lesson, an evaluation form for lesson quality, a learning achievement test, and a student satisfaction questionnaire. The results indicated that the quality of the online lesson on the Internet was rated at the highest level, (equation = 4.55, SD = 0.50). The lesson's efficiency was 81.28/80.37, which exceeded the predetermined criteria. Students' learning achievement after using the lesson (equation = 8.03) was significantly higher than before using the lesson (equation = 4.20), at a statistical significance level of 0.05. Moreover, students' satisfaction with the online lesson was rated at the highest level, (equation = 4.81, SD = 0.51).
