Abstract

Understanding stoichiometry remains a significant challenge for many secondary school students, primarily due to traditional instructional approaches that emphasize memorization rather than analytical reasoning. To address this issue, this study examines the effectiveness of a socio-scientific issue (SSI)-based problem-based learning (PBL) model in fostering students’ critical thinking skills in stoichiometry instruction. The research employed a quasi-experimental design with a non-randomized pretest–posttest control group structure. Participants consisted of two grade X classes from SMAN 1 Sipirok, with one class assigned as the experimental group receiving SSI-based PBL instruction and the other as the control group receiving conventional teaching. Data were collected through essay tests designed around Ennis’s twelve critical thinking indicators. The results of an independent samples t-test indicated a statistically significant difference in posttest scores between the two groups (p = 0.027, p < 0.05), demonstrating that the experimental group outperformed the control group in critical thinking. These findings suggest that integrating socio-scientific issues into problem-based learning can effectively enhance students’ reasoning, engagement, and conceptual understanding in chemistry education. The study contributes to the ongoing discourse on innovative pedagogies by highlighting the pedagogical potential of SSI-based PBL for cultivating higher-order thinking skills in science classrooms.

Abstract

This research is motivated by students' learning motivation which is still in the low category. Giving reward and punishment to students aims to motivate students so that they learn better. This study aims to determine whether there is an effect of reward and punishment on students' learning motivation in stoichiometry material. The subjects of this study were 10th grade students at public high school at Pekanbaru City, Indonesia. This study using a purposive sampling technique with consideration of classes having low learning motivation and obtained first class as an experimental class and second class as a control. Data collection techniques used are questionnaires, observation, and documentation. Final data analysis in this study using the t test. From the results obtained, the value of t-count = -3.720 and t-table = 2.04 at a significant level of 5% and Sig. (2-tailed) of 0.001. From this study it was concluded that t-count t-table and Sig. (2–tailed) 0.05. So the null hypothesis (H0) is rejected and Ha is accepted. This means that there is a significant effect of reward and punishment on student motivation in stoichiometric material with an effect coefficient of 10.12%.
