{"pk":33088,"title":"Collaborative Processing of Incompatible Information","subtitle":null,"abstract":"This study examined the effects of peer collaboration and \ninvestigated discourse activity employed by successful and \nunsuccessful learners in the domain of biological evolution. \nParticipants included 108 students from grades 9 and 12 \nassigned to four conditions; individual-assimilation, peerassimilation, individual-conflict, and peer-conflict. Depending \non the condition, students were asked to think aloud or \ndiscuss with their peers eight scientific statements presented \nin the order which either maximized or minimized conflict. \nSeveral measures of prior knowledge and posttest conceptual \nchange measures were obtained. There were no significant \npeer effects on conceptual change; a number of interaction \neffects indicated that peer collaboration was beneficial for \nolder students and when conflict was maximized. Indepth \nanalyses of discourse activity were conducted for four \nsuccessful and four unsuccessful leamers based on posttest \ngain scores. Unsuccessful leamers tended to assimilate \ninformation from their peers as if it were something ateady \nknown. Conversely, successful leamers were engaged in \nproblem-centred discourse moves treating new information \nfrom their peers as something problematic which requires \nexplanation. Contrasts between groups indicated significant \ndifferences in problem-centred discourse moves.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[],"section":"17","is_remote":true,"remote_url":"https://escholarship.org/uc/item/6735k8k7","frozenauthors":[{"first_name":"Carol","middle_name":"","last_name":"Chan","name_suffix":"","institution":"Saint Mary's University","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"1995-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/33088/galley/24149/download/"}]}
