Teachers’ Gestures and How They Matter

How do teachers' gestures influence students' learning? This article reviews research investigating the role of gestures in communication, focusing on teachers' communication with their students, primarily in mathematics and science instruction. We first briefly consider gesture's role in communication more generally as a backdrop for considering teaching as a special context for communication. We then describe teachers' spontaneous gesturing in teaching contexts, and we consider how teachers' spontaneous gestures might influence students' learning. We then consider experimental studies that provide causal support for the effects of teachers' gestures on students' learning. We conclude by discussing future directions and implications for educational practice.
