A beneficial effect of gesture on learning has been demonstrated in multiple domains, including mathematics, science, and foreign language vocabulary. However, because gesture is known to co-vary with other non-verbal behaviors, including eye gaze and prosody along with face, lip, and body movements, it is possible the beneficial effect of gesture is instead attributable to these other behaviors. We used a computer-generated animated pedagogical agent to control both verbal and non-verbal behavior. Children viewed lessons on mathematical equivalence in which an (...) avatar either gestured or did not gesture, while eye gaze, head position, and lip movements remained identical across gesture conditions. Children who observed the gesturing avatar learned more, and they solved problems more quickly. Moreover, those children who learned were more likely to transfer and generalize their knowledge. These findings provide converging evidence that gesture facilitates math learning, and they reveal the potential for using technology to study non-verbal behavior in controlled experiments. (shrink)

Although children learn more when teachers gesture, it is not clear how gesture supports learning. Here, we sought to investigate the nature of the memory processes that underlie the observed benefits of gesture on lasting learning. We hypothesized that instruction with gesture might create memory representations that are particularly resistant to interference. We investigated this possibility in a classroom study with 402 second‐ and third‐grade children. Participants received classroom‐level instruction in mathematical equivalence using videos with or without accompanying gesture. After (...) instruction, children solved problems that were either visually similar to the problems that were taught, and consistent with an operational interpretation of the equal sign (interference), or visually distinct from equivalence problems and without an equal sign (control) in order to assess the role of gesture in resisting interference after learning. Gesture facilitated learning, but the effects of gesture and interference varied depending on type of problem being solved and the strategies that children used to solve problems prior to instruction. Some children benefitted from gesture, while others did not. These findings have implications for understanding the mechanisms underlying the beneficial effect of gesture on mathematical learning, revealing that gesture does not work via a general mechanism like enhancing attention or engagement that would apply to children with all forms of prior knowledge.

Susan Goldin-Meadow is the 2021 Recipient of the Rumelhart Prize. Goldin-Meadow's body of research addresses the roles of gesture in language creation, communication, learning, and cognition. In one major strand of her research, Goldin-Meadow has studied gestures in children who are not exposed to any structured language input, specifically, deaf children of hearing parents who do not expose their children to sign language. These children create a highly structured, language-like system with their hands—a homesign. In another major strand, Goldin-Meadow has (...) focused on the gestures that people produce along with speech. She has examined how gestures contribute to producing and comprehending language at the moment of speaking or signing, how gestures contribute to learning language and to learning other concepts and skills, and how gestures may actually constitute and change people's thinking. This topic collection is made up of papers that represent and extend these strands of Goldin-Meadow's work. This introductory article provides a brief biography of Goldin-Meadow, and it highlights ways in which the contributions to the topic collection exemplify several notable characteristics of Goldin-Meadow's body of work, including (1) a focus on multiple timescales of behavior and behavior change; (2) use of diverse methods, approaches, and populations; and (3) considerations of equity and inclusion, both in research and in educational and clinical practice.

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. (shrink)
