Resumen:

Instructional videos for teaching second language (L2) vocabulary often feature an instructor onscreen. The instructor in the video may involuntarily produce beat gestures with their hands, as occurs in real teaching settings. Beat gestures highlight key information in speech by conveying the rhythm of the language, but do not themselves convey semantic meaning. 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. In Experiment 1, using a within-participant design, we tested the hypothesis that an instructor’s gestures (beat gesture vs. no gesture) would improve learning performance. The...

Resumen:

While the significance of the cognitive language aptitude (aptitude) and the affective second language (L2) grit for L2 achievement has been well demonstrated, their comparative contributions and the mechanisms underlying their predictive effects remain insufficiently understood. To address this gap, this study examined the predictive effects of aptitude and L2 grit on L2 achievement with foreign language learning boredom (FLLB) as a mediator. The data was collected from 156 English-major university students in China and analysed via structural equation modeling (SEM). The results indicated that (1) aptitude and L2 grit significantly and positively predicted L2 achievement with the former showing a stronger strength; (2) FLLB negatively mediated the effects of aptitude and the consistency of interest (CI) dimension of L2 grit on L2...
