Abstract

This study aims to improve the activity and learning outcomes of students using the discovery learning model on the material of basic laws of chemistry. This research was conducted in Class X.2 of SMA Negeri 6 Surabaya in the 2022/2023 academic year. This type of research is class action research which consists of planning, implementation, observation and reflection. The data analysis method in this study uses the percentage formula and the N-Gain formula. Based on the results of data analysis, it is known that student activities have increased from cycle I to cycle III.The activity of students obtained in cycle I was 54.33%, in cycle II it was 65.66%, and in cycle III it reached 82%. Experienced an increase from cycle I to cycle II by 11.33%, from cycle II to cycle III by 16.33%, and from cycle I to cycle III reached 27.66%. The learning outcomes of students also increased from cycle I to cycle III. From the calculation of the N-Gain formula, it was obtained that the increase in student learning outcomes in cycle I was 0.29 with low criteria, in cycle II it was 0.41 with moderate criteria, and in cycle III it reached 0.71 with high criteria. Based on the results of data analysis, it can be concluded that the discovery learning model can significantly improve the activities and learning outcomes of students on the basic laws of chemistry. Thus, the applied discovery learning has a positive impact on the process and learning outcomes of students in each cycle

Abstract

Through the creation of Think Pair Share-oriented E-LKPD, This study aims to enhance the ability of pupils to think critically regarding chemical equilibrium content.. The methodology of research utilized in this study is the Research and Development (R&D) approach, which was modified from Sugiyono (2015). The limited trial used One Group Pretest-Posttest Design. This study was conducted at SMAN 12 Surabaya. The validity data come from the E-LKPD's validity results, the practicality data come from the results of student activity observation and student response questionnaires, and the effectiveness data come from the critical thinking skills and student learning outcomes pre- and post-test results. From the research findings, in terms of validity, a mode score of ≥ 3 was gained for each aspect. Practicality is shown by the results of the learner response questionnaire with a percentage of 94.76%. The n-gain score findings for students in the medium and high skill categories, as well as the Sig. (2-tailed) value of 0.000, which demonstrates a substantial difference between pretest and post-test critical thinking abilities and student learning outcomes, demonstrates effectiveness. Based on these findings, it can be said that Think Pair Share-oriented E-LKPD can enhance students' critical thinking abilities concerning chemical equilibrium content.
