• Format: ePub

Produktbeschreibung

This volume is a pre-publication version of Constructing Dynamic Triangles Together: the Development of Mathematical Group Cognition, published by Cambridge University Press in 2015. These materials were last revised March 16, 2015, from the final manuscript. This version has not been edited, laid out or paginated by Cambridge University Press. Please do not cite page numbers from this version or quote from it. This version is only for informal use and may not be duplicated. Please refer to the Cambridge University Press version for official usage, citation and pagination. The book investigates the display of mathematical reasoning by the students discussing dependencies within a sequence of dynamic-geometry figures. By examining the network of their mutual chat responses preserved in computer logs coordinated with their geometric actions exhibited in a replayer, it is possible to follow in detail the meaning-making processes of the students and to observe how the team develops its mathematical group cognition by adopting a variety of group practices. The longitudinal data set provides a rich opportunity to observe cognitive development through the interplay of processes and practices identifiable at the individual, small-group and community units of analysis.

Autorenporträt

Gerry Stahl's professional research is in the theory and analysis of CSCL (Computer-Supported Collaborative Learning). In 2006 Stahl published "Group Cognition: Computer Support for Building Collaborative Knowledge" (MIT Press) and launched the "International Journal of Computer-Supported Collaborative Learning". In 2009 he published "Studying Virtual Math Teams" (Springer), in 2013 "Translating Euclid," in 2015 a longitudinal study of math cognitive development in "Constructing Dynamic Triangles Together" (Cambridge U.), and in 2021 "Theoretical Investigations: Philosophical Foundations of Group Cognition" (Springer).

All his work outside of these academic books is published for free in volumes of essays at Smashwords (or at Lulu as paperbacks at minimal printing cost).

Gerry Stahl earned his BS in math and science at MIT. He earned a PhD in continental philosophy and social theory at Northwestern University, conducting his research at the Universities of Heidelberg and Frankfurt. He later earned a PhD in computer science at the University of Colorado at Boulder. He is now Professor Emeritus at the College of Computation and Informatics at Drexel University in Philadelphia. His website--containing all his publications, materials on CSCL and further information about his work--is at http://GerryStahl.net.
