Abstract

Reflective thinking is essential for scientific reasoning and decision-making in modern education, yet many students struggle to develop this skill. This study aimed to examine the effect of integrating the Argument-Driven Inquiry (ADI) model with Science, Technology, Engineering, and Mathematics (STEM) principles-referred to as the ADI-STEM model-on students^ reflective thinking in biotechnology learning. Using a quasi-experimental design with pretest-posttest control groups, 64 tenth-grade students were divided into an experimental group (ADI-STEM) and a control group (Discovery Learning). Data were collected through validated reflective thinking tests, observation sheets, and student response questionnaires.The results showed that the ADI-STEM group achieved significantly higher posttest scores and N-Gain values compared to the control group, with the highest gains in the reacting indicator and a medium effect size. Implementation fidelity was high, and student responses indicated strong engagement and appreciation for the model^s collaborative and inquiry-oriented nature. The integration of interdisciplinary problem-solving with scientific argumentation supported students in making evidence-based reflections and decisions. These findings suggest that the ADI-STEM model is an effective instructional strategy for enhancing reflective thinking in science education. It contributes to the advancement of inquiry-based STEM pedagogy and offers practical guidance for educators aiming to foster critical and reflective learners.
