Abstract

This research aims to describe the effect of the implementation of assessment for learning (AfL) in chemistry learning on student learning outcomes. This type of research is pre-experiment. The design used in this research is One Group Pretest Posttest Design, with the same treatment in class XI, that is pretest - meeting 1 - posttest 1 - meeting 2 - posttest 2. Meetings 1 and 2 respectively are the implementation of AfL on the material of acidic buffer solutions and basic buffer solutions. The subjects of this research were students of class A and B SMAN 2 Bangkalan. Students' chemistry learning outcomes were obtained from the results of pretest, posttest 1, and posttest 2. Data analysis techniques using normality test followed by hypothesis testing and N-Gain test. The results showed that there was a significant difference between the pretest and posttest 1 and between posttest 1 and posttest 2 in classes A and B. Students' learning outcomes also improved based on the results of the N-Gain test. Based on the results of the research, it can be concluded that the implementation of AfL in learning chemistry has an effect on learning outcomes and is able to improve student learning outcomes

Abstract

This study was motivated by the topic of green chemistry, which requires an understanding of reducing or eliminating the use of hazardous chemicals for humans and the environment; therefore, innovative and engaging learning media are needed. This study aimed to determine the effectiveness of Detective Game of Chemistry in improving students’ learning outcomes on green chemistry topics. The research method used was a quantitative approach with a one-group pretest-posttest design, where the pretest was used to measure students’ initial abilities and the posttest was used to measure learning outcomes after the treatment. Data analysis was conducted using the Wilcoxon Signed Rank Test, classical completeness (mastery learning), and N-gain. The results showed a significance value of 0.001, indicating that there was an improvement in learning outcomes, as posttest scores were higher than pretest scores. The classical completeness result was 96%, categorized as very good and exceeding the success criterion of ≥75%, indicating that the learning process was effective. The N-gain analysis showed that 4% of students were in the low category, 50% in the medium category, and 46% in the high category, with an average N-gain of 0.73, which is classified as high. Based on these results, Detective Game of Chemistry is considered effective in improving students’ learning outcomes in green chemistry using an Android-based learning media.
