Abstract

This quasi-experimental study investigated the effectiveness of ChatGPT-integrated discovery learning on high school students' mathematical literacy in three-variable linear equation systems, while examining the moderating role of self-efficacy. Eighty tenth-grade students from a public high school in Indonesia were assigned to either an experimental group receiving ChatGPT-supported discovery learning instruction or a control group receiving conventional instruction, with mathematical literacy assessed through problem-solving tests and self-efficacy measured using validated questionnaires. Statistical analyses using non-parametric tests, including Wilcoxon Signed Rank Test, Mann-Whitney U Test, and Rank-Based ANCOVA, revealed that the experimental group achieved significantly higher post-test scores (M=79.25, SD=8.42) compared to the control group (M=65.30, SD=9.18), yielding a large effect size (d=1.24, p<.001) that substantially exceeded typical outcomes reported in meta-analyses of computer-assisted mathematics instruction. Contrary to established theoretical frameworks positing strong relationships between self-efficacy and mathematics achievement, this study found that self-efficacy neither significantly predicted mathematical literacy (F=3.171, p=.083, η²=.077) nor interacted with the learning model, suggesting that ChatGPT's pedagogical benefits operated uniformly across students with varying confidence levels. These findings suggest that ChatGPT functioned as adaptive conversational scaffolding that provided immediate formative feedback, facilitated metacognitive engagement through dialogic prompting, and generated multiple mathematical representations to support conceptual understanding. The null self-efficacy effect may indicate that robust AI scaffolding serves as an external compensatory mechanism that equalizes learning opportunities by reducing students' dependence on internal confidence judgments, thereby contributing novel theoretical insights into the conditional nature of motivational constructs in AI-mediated learning environments and offering practical implications for implementing conversational AI in mathematics education.

Abstract

Background: Critical thinking skills are essential in addressing the learning challenges faced by students in the 21st century. To foster these skills effectively, it is necessary to adopt specific instructional approaches that enhance students’ mathematical critical thinking within the classroom setting.Aims: This study aims to investigate students’ critical thinking abilities in mathematics during the implementation of the Argumentation-Based Learning Process (ABLP) in classroom instruction.Methods: A qualitative case study design was employed, involving 30 eighth-grade students from an A-accredited school in Indonesia. Data sources included ABLP-based worksheets, audio recordings of student group discussions, and interview transcripts. The collected data were analyzed using a triangulation strategy to ensure accuracy, and peer reviews were conducted to validate the findings. The analysis focused on identifying indicators of critical thinking skills at each stage of the ABLP model.Results: The results show that students demonstrated various levels of critical thinking throughout the ABLP stages. However, not all students consistently met the predetermined indicators at each stage of the process. Despite these variations, the findings suggest that ABLP can be an effective pedagogical approach to foster students’ critical thinking in mathematics.Conclusion: This study concludes that ABLP offers meaningful opportunities for students to develop critical mathematical thinking and should be considered as a strategy in mathematics instruction.
