An Analytical Examination of VoiceThread Engagement Patterns of Pre-and In-Service Teachers in an ESL Graduate Course

Investigating Posting Frequencies, Response Modalities, and Demographic Influences

Abstract

This study analyzes graduate students’ engagement with VoiceThread, a multimodal discussion platform that blends audio, video, and text. Drawing on data from 94 pre- and in-service teachers enrolled in an eight-week online English Language Development course, we examined three dimensions of participation: posting frequency, response length, and modality choice. Descriptive statistics, Pearson’s correlation, and ANOVA were employed to analyze 1,128 student comments across six sections. Results revealed a strong preference for audio contributions, which comprised 83% of postings and totaled more than 40 hours of discourse. A small but significant correlation indicated that frequent posting was associated with slightly longer responses, while variation in audio length across sections indicates the influence of instructor presence. High-engagement sections, where instructors modeled active use of the platform, yielded richer and longer contributions compared to low-engagement sections. These findings suggest that while VoiceThread’s affordances facilitate interaction, meaningful engagement is shaped less by the tool itself than by instructional design and teaching presence.
