Interactions Beyond the Pandemic: Lessons Learned from Large-scale Emergency Remote Teaching in Higher Education

CHI 2025 Emergency Remote Teaching (ERT) during COVID-19 offered a unique chance to study online higher education at scale, beyond traditional lab settings. Through a review of 22 empirical studies, we analyzed how online classrooms addressed different types of interaction. Our findings highlight the need for future research that centers Learner-Content interaction as a way to balance flexibility with structure—especially as ERT may continue to shape education going forward.

Towards Dialogic and On-Demand Metaphors for Interdisciplinary Reading

CHI 2025 Interdisciplinary engagement across disciplines is often hindered by stylistic and conceptual differences. Drawing on Large Language Models (LLMs), this work explores how metaphor-based support can improve accessibility and engagement. A survey of early-career HCI researchers found that metaphors increased interest in STS texts, particularly for those with limited prior exposure. We propose a dialogic model of metaphor exchange to support shared understanding and critical reflection across disciplines.

Adjacent Display of Relevant Discussion Helps Resolve Confusion

CSCW 2021Adjacent Display of Relevant Discussion (ADRD) keeps a video’s comment thread in sync with playback time, showing on-topic Q&A beside the video and— in a 20-person study—helping viewers quickly resolve confusions, explore comments, and interact more with the content.

“It Feels Like I am Talking into a Void”: Understanding Interaction Gaps in Synchronous Online Classrooms

CHI 2021 This paper investigates in-class interactions in synchronous online classrooms when the choice of modality is discretionary, such that students choose when and if they turn on their cameras and microphones
