Abstract

Misconceptions in learning chemical equilibrium remain a persistent challenge that can hinder students' understanding and academic confidence. Despite various efforts to improve conceptual mastery, many students still harbor incorrect notions that affect their learning outcomes and self-belief. To address this issue, this study explores the relationship between students' misconceptions and their self-efficacy regarding chemical equilibrium concepts. The research employed a research and development approach using the ADDIE model, utilizing an Android-based five-tier multiple choice test as a diagnostic instrument. A random sampling technique was applied to select three senior high schools in Pekanbaru: SMAN 8 Pekanbaru, SMAN Olahraga Provinsi Riau, and SMAN 3 Pekanbaru. A correlation test was conducted to determine the presence, direction, and strength of the relationship between students' misconceptions and their self-efficacy. The results revealed a positive correlation between the two variables across schools with high, medium, and low academic profiles

Abstract

This paper discusses the effect of an interactive engagement strategy using Quizizz on students' critical thinking skills on chemical bonding material. This research used a quasi-experimental design because not all factors influencing learning can be controlled. This research was conducted in two experimental classes, the experimental and the control classes. The experimental class was given treatment in the form of an interactive engagement strategy using Quizlet. And the control class was given conventional model treatment. The sampling technique in this research is purposive sampling, which considers the homogeneity of the sample (class). The experimental and control class samples were 29 students from class X at MAN 1 Pekanbaru. The research results show that the ability to infer, namely making conclusions and presenting problems, dominates with the highest percentage value of 85%. On the other hand, analytical skills, which involve finding causes, assessing impacts, and predicting further impacts, recorded the lowest percentage with 50%. Overall, the average percentages for the four indicators reached 67.5%, which is in the good category. The Independent Sample T-Test statistical test, with a significance value (sig) of 0.000, revealed a significant difference in scientific literacy abilities between experimental and control class students. Of the N-Gain analysis, it is known that the average gain score for critical thinking skills in the experimental class (0.50 or 50%) is in the medium category, while the control class only reached 0.30 (30%), which is included in the low category. This shows a more significant increase in learning outcomes for critical thinking skills in the experimental class compared to the control class.
