Dialogic approaches based on active student participation, open, respectful discussion, exploring and critiquing different perspectives are increasingly found to support student learning. However, the specific productive forms of teacher-student interaction have rarely been studied systematically. A recent large-scale project explored the…

It is now widely believed that classroom dialogue matters as regards student outcomes, with optimal patterns often regarded as requiring some or all of open questions, elaboration of previous contributions, reasoned discussion of competing viewpoints, linkage and coordination across contributions, metacognitive engagement with dialogue, and high…

Research into classroom dialogue suggests that certain forms are especially productive for students' learning. Despite the large number of studies in this area, there is inadequate evidence about the prevalence of the identified forms, let alone their productivity. However, scarcity is widely presumed. The overall aim of the study reported in this…

This paper describes research on dialogue between teachers and pupils during primary school science lessons, using talk from two classrooms to provide our examples. We consider whether teachers use dialogue to make education a cumulative, continuing process for guiding the development of children's understanding. Case studies of two teachers,…

Findings from observations of 64 8- and 9-year olds show that the use of exploratory talk, talking in which joint reasoning is made explicit, can improve group reasoning and that this exploratory talk can be taught and can transfer between educational contexts. Teaching exploratory talk also improved results on a nonverbal reasoning test. (SLD)
