Abstract

This research aims to create POGIL-based E-Worksheet learning media on Covalent Bond material to increase students' learning independence. This research uses R&D (Research and Development) research to produce and test the effectiveness of media by adapting the model developed by Plomp (2010). The subjects of this research were class XI students of SMAN 1 Menganti. The validity results based on assessments from experts were found to be 85.7% for content validity which was included in the very valid criteria and 90.7% for construct validity which was included in the very valid criteria. This E- Worksheet is also considered practical in terms of the student response questionnaire with a score of 77.3% or in the very practical category and the results of observations of student activities obtained a score of 88.9% or in the very practical category. Furthermore, the effectiveness results based on the learning independence questionnaire obtained an n-gain score of 0.71 or in the high category. Based on these results, this E- Worksheet can be used as a learning medium to increase students' learning independence.

Abstract

This study aims to determine the effectiveness of using the Brain Out Chemistry learning media in This study aims to determine the effectiveness of the Brain Out Chemistry game-based media in improving students’ cognitive abilities, learning activities, and retention of learning outcomes on the Periodic System of Elements. The research was conducted at SMA Negeri 15 Surabaya involving 34 tenth-grade students using a One-Group Pretest–Posttest Design. The research instruments included cognitive tests (pretest, posttest 1, and posttest 2 as the retention test) and student activity observation sheets. Data were analyzed using the Wilcoxon Signed Ranks Test through SPSS. The results showed a significant increase between the pretest and posttest scores (sig. 0.000 < 0.05). The average score of posttest 1 was 85.87, which decreased to 76.86 in posttest 2, resulting in a retention value of 89,5%, categorized as high. Student learning activities also improved, as indicated by observation scores falling within the active category. Classically, the learning mastery rate exceeded 85%. Thus, the Brain Out Chemistry game-based media is effective because it enhances cognitive abilities, maintains learning retention, and promotes student learning activities in chemistry instruction.
