Connecting geometric concepts and chemistry through 3D printing: an integrated STEM module for preservice teachers

This study examines the implementation of an integrated STEM module in a mathematics content course for preservice elementary teachers (PSETs). The module was designed to deepen conceptual understanding and foster interdisciplinary reasoning by connecting geometric concepts—such as area, volume, and scaling—with chemistry content on crystal lattice structures and 3D printing technology. Grounded in the Scholarship of Teaching and Learning (SoTL) framework, the module incorporated inquiry-based learning, collaborative problem-solving, and a community-based experiential learning (CBEL) component. Mix methods were utilized findings indicate that PSETs improved their understanding of geometric concepts and strengthened their ability to apply mathematics in real-world contexts. Reflections also revealed increased confidence in integrating STEM approaches into future teaching, highlighting the module’s potential to support teacher preparation.
