This study investigates the effectiveness of a Kinect-based 3D embodied interaction game designed to teach middle school students fundamental concepts of electrical circuits from a microscopic perspective, particularly focusing on LC resonance. In the game, students embody a charged particle, experiencing circuit connectivity through a micro-level, first-person viewpoint. Traditional circuit education often struggles to convey the abstract movements of electrons clearly, making it challenging for students to intuitively grasp microscopic electrical phenomena. By emphasizing the role of physical engagement in micro-level circuit cognition, this game provides students with an immersive and intuitive educational experience. Our findings indicate significant improvements in students' conceptual understanding and enhanced experiential engagement compared to conventional instructional methods. This research underscores the potential of embodied interaction in deepening STEM learning and offers insights into the cognitive and experiential benefits of using body-based interactions in educational contexts.
