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

Developing students’ critical thinking skills remains a major challenge in chemistry education, particularly in thermochemistry, which requires conceptual, symbolic, and quantitative reasoning. While STEM-integrated problem-based learning (PBL–STEM) has gained increasing attention, limited studies have examined how this instructional approach aligns with the cognitive structure of critical thinking. This study investigated the effect of the PBL–STEM model on students’ critical thinking skills in thermochemistry. A quasi-experimental design involving 64 tenth-grade students was employed. Participants were selected using purposive sampling and assigned to an experimental group and a control group. Critical thinking skills were measured using a 20-item essay test based on Facione’s framework. The instrument demonstrated high reliability (Cronbach’s α = 0.915) and strong content validity (CVI = 0.93). Data were analyzed using an independent-samples t-test. Results showed a significant difference between groups (t = 4.997, p < 0.05), with the experimental group achieving higher mean scores (M = 80.80) than the control group (M = 65.38). The effect size (Cohen’s d = 1.25) indicates a large instructional impact. These findings suggest that STEM-integrated PBL provides a cognitively aligned framework for fostering critical thinking in chemistry learning.

Abstract

Chemistry learning at the high school level often faces challenges in how to create interesting and fun learning for students. the current paradigm of chemistry subjects is often considered scary by students, so it is necessary to take an innovative approach with the main focus of this service is to create a positive and inspiring learning experience in the school environment, motivating students to be more actively involved in chemistry learning. The service aims to explore the implementation of fun chemistry practicum as a strategy to increase students' interest in learning at SMA Negeri 1 Pagimana. This practicum was designed with the aim of changing the conventional chemistry learning paradigm into a fun and memorable experience. Through interactive and visual experiments, students are invited to actively participate in practical activities involving simple chemical reactions and demonstrations that arouse their curiosity. The initial evaluation showed a positive change in students' behavior as seen from their enthusiasm in participating in this activity.
