Asynchronous peer teaching using student-created multimodal materials

This paper reports on asynchronous peer teaching in which learners create multimodal explanations or tutorials for future cohorts. Japanese learners of English work individually or in teams to produce video and audio explanations. Multimodal explanations that meet the quality requirements are uploaded to the respective course websites housed on the university server. The aim is that student audio-visual developers learn during the creation process and student users learn from the multimodal resources developed. Each year a new cohort of students makes a new set of explanations. The mean quality of the multimodal explanations increases annually as the less useful or less popular video and audio files are replaced. This creates a continuous cycle of incremental improvement.
