Abstract

This study examines the concept and structure of modeling competence and proposes a model-based approach to physics teaching intended to develop this competence. Based on this approach, the authors designed and implemented a learning activity on radioactive decay that integrated the COACH platform, a tool for simulation, data collection, and analysis in physics education. Designed within a STEM-oriented framework, the lesson engaged students in modeling tasks such as simulating radioactive decay, constructing nuclear reaction models, analyzing collected data, and validating models. Findings from classroom observations and teaching experiments indicate that students demonstrated key aspects of modeling competence by identifying the underlying nature of physical phenomena, using digital tools to construct and test models, and evaluating and revising models based on experimental data.
