Abstract

This study aimed to develop a differentiated teaching module to enhance students' scientific argumentation skills on chemical bonding material. The method used was Research and Development (R&D) with the 4D model (Define, Design, Develop, Disseminate). Validation results from experts showed that the developed differentiated teaching module was highly valid (92% and 94%), very practical (100% and 97%), and effective, with more than 80% of students achieving the minimum competency standard (KKM) and an average score of 88. The improvement in scientific argumentation skills was reflected in the average pre-test score of 64, which increased to 80 in the post-test. Specifically, the indicators of scientific argumentation showed improvement: claims increased from 62.9% to 75.4%, data from 66.3% to 84%, warrants from 67.8% to 82.1%, and backings from 68.4% to 79.4%. The increase in scientific argumentation scores from pre-test to post-test indicates that the developed teaching module was effective in helping students hone their argumentative skills. However, the ability to formulate claims and backings still requires reinforcement, as they demand a more complex understanding. Nevertheless, this improvement suggests that the differentiated teaching module created and implemented can strengthen students' scientific argumentation skills in understanding chemical bonding material, making it recommended for broader application, especially in science education.

Abstract

This study investigates the mediating role of epistemic agency in the relationship between students’ perceptions of constructivist learning environments and their conceptual understanding in Indonesian chemistry classrooms. A sequential explanatory mixed-methods design was employed, integrating quantitative and qualitative approaches. In the quantitative phase, data were collected from 712 high school students across five schools using an adapted Constructivist Learning Environment Survey (CLES) and a three-tier diagnostic chemistry test. Rasch modeling confirmed the strong psychometric properties of the adapted CLES, while structural equation modeling (SEM) revealed that epistemic agency significantly mediated the relationship between classroom environment perceptions and conceptual understanding. In the qualitative phase, thematic analysis of interviews with 12 selected students uncovered three dominant themes contributing to misconceptions: limited dialogic space, lack of contextualization, and teacher-dominated instruction. The integration of both data strands demonstrates that epistemic agency is not only influenced by pedagogical practices but also shaped by cultural norms. These findings extend the dual-path learning framework by embedding agency as a key mechanism for conceptual change. Pedagogically, the results underscore the need for dialogic, student-centered learning environments that promote active participation and reduce misconceptions. Policy-wise, the findings align with the OECD Learning Compass 2030 and Indonesia’s Merdeka Belajar curriculum, emphasizing the importance of agency-oriented strategies in achieving global education standards.

Abstract

This study aims to evaluate the suitability of data obtained from the Constructivist Learning Environment Survey instrument and a multiple-choice chemistry understanding test, as well as to examine the relationship between students' perceptions of the constructivist learning environment and their understanding of chemistry concepts. A non-experimental, quantitative descriptive approach was employed, involving 519 12th-grade science students from five high schools in Gorontalo Province during the even semester of the 2024/2025 academic year. Data analysis was conducted using the Rasch model via Winsteps 3.73 software to assess instrument quality, and SPSS software to test data normality and analyze correlations. The results indicated that both instruments were valid and reliable, with person reliability of 0.81, item reliability of 0.99, and Cronbach’s Alpha exceeding 0.80—classified as excellent. A Pearson correlation analysis revealed that the calculated r value exceeded the critical value (rcount= 0.135 > rtable= 0.087), indicating a statistically significant, albeit weak, positive relationship between students’ perceptions and their chemistry understanding. The hypothesis testing results showed that the null hypothesis (H₀) was rejected and the alternative hypothesis (H₁) was accepted, confirming the existence of a relationship between students’ perceptions of constructivist learning environments and their understanding of chemistry concepts.

Abstract

Measuring critical thinking skills (CTS) in the topic of atomic structure requires a diagnostic instrument capable of capturing students' reasoning patterns accurately, rather than merely distinguishing between correct and incorrect answers. This study aimed to develop and evaluate a complex multiple-choice diagnostic instrument based on the Rasch model to measure students' CTS on the concept of atomic structure. The instrument comprised ten items developed based on Facione's six dimensions of critical thinking: interpretation, analysis, evaluation, inference, explanation, and self-regulation. Data were collected from 850 senior high school students in Gorontalo, Indonesia, and analyzed using the Partial Credit Model (PCM) approach with WINSTEPS 4.5.5 software. Results indicated that item reliability was very high (0.99; separation = 10.63), while person reliability was moderate (0.61; Cronbach's Alpha = 0.65). Infit and Outfit MNSQ values ranged within the ideal threshold (0.99–1.00) with ZSTD values approaching zero, confirming adequate model fit. Category Probability Curve (CPC) analysis confirmed that response categories functioned sequentially, while the Wright Map demonstrated a progressive difficulty hierarchy from the interpretation to the self-regulation dimension. Differential Item Functioning (DIF) analysis revealed differential difficulty levels based on gender and grade level, particularly for self-regulation items, which proved more challenging for female students and Grade XI students. These findings underscore the importance of considering cognitive factors and learning experience in developing Rasch-based CTS diagnostic instruments for chemistry education
