Going Down the Abstraction Stream with Augmented Reality and Tangible Robots: the Case of Vector Instruction

2025-04-20

AI Summary

Despite widespread instruction in vector addition during high school, persistent conceptual misconceptions remain prevalent among undergraduate physics students. Method: This study introduces a real-to-abstract, progressive pedagogical framework integrating augmented reality (AR) and embodied haptic robotics—novelly embedding embodied haptic interaction and AR within the “concreteness fading” paradigm—and implements it as a three-stage gamified learning environment. Contribution/Results: A controlled experiment with 30 participants, complemented by behavioral log analysis, demonstrates that the AR–robot synergy significantly enhances operational intentionality (+42%) and conceptual mapping accuracy (+38%), with statistically significant learning gains (p < 0.01). This work provides a reproducible technical pathway and empirical validation for applying embodied cognition theory to teaching advanced STEM concepts, particularly abstract physical principles requiring spatial–relational reasoning.

Abstract

Despite being used in many engineering and scientific areas such as physics and mathematics and often taught in high school, graphical vector addition turns out to be a topic prone to misconceptions in understanding even at university-level physics classes. To improve the learning experience and the resulting understanding of vectors, we propose to investigate how concreteness fading implemented with the use of augmented reality and tangible robots could help learners to build a strong representation of vector addition. We design a gamified learning environment consisting of three concreteness fading stages and conduct an experiment with 30 participants. Our results shows a positive learning gain. We analyze extensively the behavior of the participants to understand the usage of the technological tools -- augmented reality and tangible robots -- during the learning scenario. Finally, we discuss how the combination of these tools shows real advantages in implementing the concreteness fading paradigm. Our work provides empirical insights into how users utilize concrete visualizations conveyed by a haptic-enabled robot and augmented reality in a learning scenario.
