Description

CORDTRA stands for Chronologically-ordered Representations of Discourse and Tool-Related Activity. The Hmelo-Silver, Chernobilsky, and Jordan study uses "CORDTRA diagrams in order to demonstrate how visually representing the chronology of tool use and discourse in an activity can enhance analysis of collaborative learning in a computer supported learning environment." Their analyses locate differences in how students use resources and engage in metacognitive talk and knowledge transforming activities, sometimes to the group's detriment.

• CORDTRA diagrams for visually representing the chronology of tool use and discourse in collaborative learning analysis: CORDTRA stands for Chronologically-ordered Representations of Discourse and Tool-Related Activity.

• CORDTRA — Chronologically-Ordered Representations of Discourse and Tool-Related Activity: CORDTRA is a technique introduced in the Hmelo-Silver, Chernobilsky, and Jordan study for visually representing collaborative learning processes in a computer-supported learning (CSCL) environment. By "visually representing the chronology of discourse and tool use (such as a personal notebook, electronic whiteboard) associated with an activity", it gives a better overview of collaborative learning processes in computer-mediated problem-based learning. The commentary judges it very promising but notes its outcome measures need firmer links to a constructivist theoretical framework. (Remy M. J. P. Rikers et al. (2008))
