This study investigates whether gestures can be used during recasts to enhance the saliency of a target structure (locative prepositions) and to lead to better production of the target structure. Forty-eight low-intermediate English as a second language (ESL) students partook in communicative activities during which they received either no feedback (control), verbal recasts only (R), or recasts plus gesture (RG), and a subset of participants completed a stimulated recall session. Then the pretest, immediate, and delayed posttest scores of grammar and oral production tests were used to analyze the linguistic development. The results showed that no one commented on recasts or locative prepositions during the stimulated recall session and that there were no significant changes in grammar test scores in all conditions; however, the R and RG conditions performed significantly better in the production test than the control in the immediate posttest. Furthermore, the RG condition maintained the development in the delayed posttest, whereas the R condition did not.
