{"product_id":"9781316444146","title":"Constructing Dynamic Triangles Together: The Development of Mathematical Group Cognition","description":"Rational thinking as exemplified in mathematical cognition is immensely important in the modern world. This book documents how a group of three eighth-grade girls developed specific group practices typical of such thinking in an online educational experience. A longitudinal case study tracks the team through eight hour-long sessions, following the students' meaning-making processes through their mutual chat responses preserved in computer logs coordinated with their geometric actions. The examination of data focuses on key areas of the team's development: its effective team collaboration, its productive mathematical discourse, its enacted use of dynamic-geometry tools, and its ability to identify and construct dynamic-geometry dependencies. This detailed study of group cognition serves as a paradigmatic example of computer-supported collaborative learning, incorporating a unique model of human-computer interaction analysis applied to the use of innovative educational technology. A valuable resource for researchers, instructors, and students alike, it offers concrete suggestions for improving educational practice.","brand":"Cambridge University Press","offers":[{"title":"Default Title","offer_id":47122130764016,"sku":"9781316444146","price":88.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9781316444146_p0.jpg?v=1763707404","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9781316444146","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
