Mapping the Methodological Space of Classroom Interaction Research: Scale, Duration, and Modality in an Age of AI
For researchers in classroom interaction, this framework helps clarify methodological trade-offs and guide study design, but it is a conceptual contribution without empirical validation.
The paper proposes a framework to map classroom interaction research along scale, duration, and modality, illustrating it with contrasting studies and an interview, and examines how AI expands this space.
Research on classroom interaction has long been divided between large-scale observation and in-depth ethnographic work. We propose a framework mapping this methodological space along three dimensions--scale, duration, and modality--where a study's position shapes what it reveals and obscures. We illustrate it through contrasting studies of dialogic teaching--Howe et al. (2019) and Snell and Lefstein (2018)--and an interview with the lead researchers, organized around three questions: what can be operationalized, what mechanisms become visible, and what translates to practice. We then examine how AI is expanding this space and how the framework can guide research and tool design.
