Highlights

  • Investigated the students' performance by assessing the quality of comments they make in a video-based learning platform.

  • Proposed quality nudges, i.e. personalised interventions to encourage students to write better quality comments.

  • Investigated the effectiveness of quality nudges on engagement, learning and the learners' subjective opinion on the nudges.

Abstract

Developing and maintaining constructive engagement is a crucial challenge in learning by watching videos. AVW-Space is an online video-based learning platform which enhances student engagement via note-taking and personalised support. Previous studies with AVW-Space show that students who write comments, especially high-quality comments, learn more. The goal of the study reported in this paper is to encourage students to write better-quality comments. After automating the assessment of comment quality using machine learning approaches, we developed Quality nudges which encourage students to write better comments. We conducted a study in a first-year engineering course to analyse the learning effects of the Quality nudges. The results show that Quality nudges enhanced constructive engagement and learning. The contribution of this research is in proposing methodology for increasing the quality of student comments in video-based learning.
