It is commonly observed that during classroom or group discussions some students have greater influence than may be justified by the normative quality of those students' contributions. We propose a 5-component theoretical framework in order to explain how undue influence unfolds. We build on literatures on persuasion, argumentation, discourse, and…

Structured argumentation support environments have been built and used in scientific discourse in the literature. However, to the best our knowledge, there is no research work in the literature examining whether student's knowledge has grown during learning activities with asynchronous argumentation. In this work, an intelligent computer-supported…

Research has addressed what instructional conditions may inhibit or promote scientific argumentation. Little research, however, has paid attention to interpersonal factors that influence collaborative argumentation. The present study examines the ways interpersonal factors affected group dynamics, which influence the features of collaborative…

Is it feasible to hold concurrent, small-group, peer-managed discussions in large elementary school classes? We sought an initial answer to this question in a fifth-grade class in Hefei, China. The 52 students in the class were divided into seven small groups. The seven groups held four simultaneous discussions without immediate supervision or…

This article reports the findings of a research project concerned with children engaging in scientific argumentation. Discussion activities were designed to enable groups of children to use evidence when making decisions. The findings show a variation in the success with which children construct scientific arguments; some groups debate most of the…

To illuminate the processes of creating learning communities, this study investigated the social context of an inclusion classroom by examining (a) how teachers established a community ethos, (b) how students responded with regard to the positioning of students with disabilities, and (c) how macro discourses possibly shaped interactional…

This article presents the first results of an investigation in a scholastic context aimed a determining the conditions that favour the acquisition of knowledge in biology within interactions in groups of 4 pupils. There were three work sessions in small groups, and some sessions in class groups. The pupils' conceptions were assessed at the…
