Constructing Dynamic Triangles Together (Gerry Stahl's eLibrary, #6)

by Gerry Stahl

Overview

Rational thinking as exemplified in mathematical cognition is of undeniable importance in the modern world. This book documents how a group of three eighth-grade girls developed specific practices typical of such thinking through involvement in an online educational experience. The presentation begins by discussing the methodological approach adopted in analyzing the development of mathematical group cognition. An extended case study then tracks the team of students step by step through its eight-hour-long progression. Concluding sections draw the consequences for the theory of group cognition and for educational practice.

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.
