Holding the Room: Designing Interaction without Technology in Large Chinese University Lectures

Abstract

In Chinese universities, undergraduate lectures of eighty to one hundred and thirty students have become the norm. Faced with such rooms, teachers often feel that meaningful interaction is out of reach without technological support: smart response systems, live bullet-screen chat, or AI-mediated question platforms. This paper argues that the bottleneck in large lectures is design, not technology. It proposes that “interaction” in a large room should be redefined away from public speech by a few visible students and toward a ninety-second cognitive operation in which every student is engaged at the same time. Drawing on recent empirical work on active learning, retrieval practice, and large-class teaching, the paper identifies three structural constraints of the Chinese large lecture—the voice problem, the accountability problem, and the timing problem—and translates them into three reusable, no-technology interaction patterns: neighbour recount, folded-paper vote, and three-sentence exit. Holding the attention of a hundred or so students is a design task, and a smart classroom platform can support—but hardly replace—the teacher’s weekly practice of inserting three ninety-second cognitive contracts into a forty-minute lecture.
