Comparing MOOC Learners Engagement with Japanese Videos and Text to Speech Generated English Videos

Published: 01 June 2022 Publication History

Abstract

In recent years, massive open online courses (MOOCs) have been rapidly growing with learners from both English and non-English speaking countries. Nowadays, many MOOC developers provide transcripts in multiple languages to attract a broader range of learners. However, providing transcripts is ineffective for visually impaired learners and tends to divert learners' attention away from the overall content of the video lecture. Thus, aside from offering English transcripts, Japanese lecture videos in the Tokyo TechIntroduction to Electrical and Electronic Engineering MOOC were automatically dubbed into English with a computer-generated voice. To understand the effect of English-automatically dubbed videos on learners, the learners' interactions, video completion rate, and course completions were compared to the original course in Japanese. The results show that English automatically dubbed videos have an overall high learner engagement when compared to Japanese videos with English transcripts. Survey results on learners' satisfaction towards the English dubbed videos also showed higher positive responses. These results show the effectiveness of dubbing Japanese lectures into English using text-to-speech technology which has signification for MOOCs offered in various languages.

In this presentation, the learners? engagement in two edX Massive Open Online Courses (MOOCs) entitled, Introduction to Electrical and Electronic Engineering (EE), released by the Tokyo Institute of Technology was examined. The analysis was performed on Japanese lecture videos with English transcripts released in 2017 (EE2017) and the English automatically dubbed videos with a computer-generated voice using text-to-speech technology in 2021 (EE2021). In order to understand the effect of English automatically dubbed videos on learners, the learners' interactions towards videos, video completion, and course completion, were analyzed and compared to the Japanese videos with English transcripts. The results show that English automatically dubbed videos have an overall higher learners' engagement when compared to Japanese videos with English transcripts. Moreover, the survey results on learners? satisfaction towards the English automatically dubbed videos also showed highly positive responses.
