An important part of "doing" science is engaging in collaborative science practices. To better understand how to support these practices, we need to consider how students collaboratively construct and represent shared understanding in complex, problem-oriented, and authentic learning environments. This research presents a case study…

We examine how extended engagement in argumentation with peers leads to enhanced metalevel understanding of argumentive discourse. Following such engagement, young adolescents demonstrated enhanced understanding of counterargument and use of evidence as objectives of skilled argumentation, relative to a nonparticipating comparison group. Among the…

The micro-time context of group processes (such as argumentation) can affect a group's micro-creativity (new ideas). Eighty high school students worked in groups of four on an algebra problem. Groups with higher mathematics grades showed greater micro-creativity, and both were linked to better problem solving outcomes. Dynamic multilevel analyses…

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 study examined how message-response exchanges produced in the interactions between active learners only, reflective learners only, active-reflective learners and reflective-active learners affected how often active versus reflective learners posted rebuttals to arguments and challenges across four types of exchanges that believed to promote…

This study investigated the collaborative decision-making and communicative discourse of groups of learners engaged in a simulated medical emergency in two conditions. In one condition subgroups used a traditional whiteboard (TW group) to document medical arguments on how to solve a medical emergency. In the other condition subgroups used…

This study examined the effects of conversational language (e.g., asking questions, inviting replies, acknowledgments, referencing others by name, closing signatures, "I agree, but", greetings, etc.) on the frequency and types of responses posted in reply to given types of messages (e.g., argument, evidence, critique, explanation), and…

Examines the rhetoric of "popular" atheists in the U.S. and argues that their rhetoric possesses distinctive features that are the natural results of existential failure. (MH)

Replies to Billig's (1995) critique of his paper on the relations between language and ideology. The article argues that the paper critiqued is tentative and maintains that social cognition should not be reduced to structures of interaction or rhetoric. The article also emphasizes that ideologies are crucial in the cognitive and social management…

Discusses a case study of the interaction between the New Christian Right, or Moral Majority, and its humanist opponents. Concludes that because the groups argue from incompatible premises, they cannot share a common moral framework within which to agree. Labels the rhetoric of the two groups reciprocated diatribe. (SRT)

This study examined the effects of pre-structuring discussion threads on group performance in computer-supported collaborative argumentation where students labeled their messages as arguments, challenges, supporting evidence, and explanations on a threaded discussion board. In the pre-structured group students were required to post supporting and…

An examination of the rhetoric of two social movements in the United States--the proslavery movement of the pre-Civil War Period and the anti-feminist movement of the 1970s--reveals that both contain a common theme, paternalism, and that both use similar rhetorical strategies to explicate the theme through a familial metaphor, Father. Examples of…

An ethnographic and linguistic study conducted at a high-technology corporation examined decision-making in managerial meetings, focusing on the effects of silences following a proposal on the maker of the proposal. An opinion is that such silences signify a negative evaluation of the proposal, inviting the proposal maker to alter his position.…

A study investigated the interpersonal dynamics occurring in an ungraded bilingual education class of native Spanish-speaking students in an ungraded primary classroom (with 10-12 students each from grades one, two, and three) at Garamond Elementary School in a working class community southeast of Los Angeles, California. Six classroom sessions…

This study tested the effects of linguistic qualifiers and intensifiers on the number and types of replies elicited per argument and per challenge posted in online debates. To facilitate collaborative argumentation, thirty-two students (22 females, 10 males) enrolled in a graduate-level online course classified and labeled their messages as…
