However, little is known about how the instructor’s beat gestures affect L2 vocabulary learning. We conducted two experiments on the effects of the instructor’s purposeful (scripted) beat gestures in instructional videos that included an instructor and slides, with English L2 vocabulary as the topic.

Effects were measured in terms of participants' judgments of learning and objective measures of learning performance (indicated by accuracy on immediate and delayed...
