Current research on cross-language transfer has focused primarily on literacy development. The present study extends the scope of existing research by focusing on argumentative reasoning, an important but under-research academic skill. A single-case study with a reversal design was conducted with four Chinese-English elementary students with the…

This study examined the influence of teachers' instructional moves on students' relational thinking during small-group collaborative discussions. One hundred and twenty 4th grade students and 6 teachers participated in a series of 10 discussions, generating a video-recorded corpus containing 32,511 turns for speaking. A microanalysis of a subset…

The influence of one teacher's scaffolding moves on children's performance in free-flowing child-led small-group discussions was investigated. Three moves were examined: prompting for and praising the use of evidence, asking for clarification, and challenging. Lag sequential analysis was applied to a corpus of over 5,300 speaking turns during 30…

In this paper, we address the need to develop an empirically-based understanding of the use of dialogue in teaching by discussing theory and research related to a pedagogical approach called collaborative reasoning (CR). CR is an instructional method designed to engage elementary school children in group discussions about controversial issues…

This microgenetic study examined social influences on children's development of analogical reasoning during peer-led small-group discussions of stories about controversial issues. A total of 277 analogies were identified among 7,215 child turns for speaking during 54 discussions from 18 discussion groups in 6 fourth-grade classrooms (N = 120; age…

This study systematically analyzed social and cognitive processes that underlie the development of argumentative knowledge. Group discussions of controversial issues and explicit instruction in argumentation were expected to help students acquire a sense of the overall structure of an argument, or an argument schema. In a quasi-experiment, 128…

Emergent leadership was examined in 12 discussion groups in 4 fourth-grade classrooms. Children's leadership moves were coded from transcripts of 10 free-flowing, open-format discussions of each of the 12 groups. The transcripts encompassed 26,000 turns for speaking, including 22,000 child turns of which 1,700 were judged to serve one of five…
