Watching hands move enhances learning from concrete and dynamic visualizations.

Abstract

This article explores the role of sensorimotor engagement in students' learning of a challenging science, technology, engineering, and math-related concept. Previous research has failed to distinguish two features commonly associated with embodiment: sensorimotor engagement and visuospatial concreteness. In the current research, we ask whether sensorimotor engagement-operationalized as watching a video of hands manipulating paper representations-offers unique benefits beyond the visuospatial concreteness of a dynamic visualization of the same process. Participants were randomly assigned to one of three conditions to learn about the shuffle() function in R: a Watch Hands Moving Objects group, which watched a video with hands; a Watch Moving Objects group, which watched a video with a dynamic visualization in which objects moved without hands; or a control group, which watched a live-coding video that did not include either hands or visuospatial representations. Results revealed that only participants in the Watch Hands Moving Objects group demonstrated significantly superior performance compared with both the Watch Moving Objects group and control groups. These findings highlight the unique benefit of sensorimotor engagement for learning, contributing to a deeper understanding of how embodiment can enhance the learning process.
