The effects of feedback type and explicit associative memory on the effectiveness of delayed corrective feedback in computer-mediated communication

Abstract

The present study examines the impact of the explicitness of corrective feedback and explicit associative memory on the acquisition of -ing/-ed participial adjectives through delayed video-based corrective feedback. Fifty-two L1 Spanish learners were randomly assigned to one of three groups (implicit, explicit, or no-feedback) and performed an interactive task with an experimenter via a video-conferencing tool without receiving any feedback. At the end of the task, the feedback groups received a video replay with inserted oral corrections (either partial recasts or explicit corrections). The no-feedback group performed the interactive task without receiving corrective feedback. A paired-associates test with delayed recall was used to measure explicit associative memory. Pretest-posttest development was measured using oral production and grammaticality judgment tasks. Both corrective feedback groups outperformed the nofeedback group. While no statistical difference emerged between the two delayed corrective feedback groups, a small difference was detected for the explicit group when considering effect sizes. Moreover, a positive relationship was found between explicit associative memory and learning gains on the grammaticality judgment task.
