Representational Competence: A Commentary on the Greeno Analysis of Classroom Practice

Abstract

In his analysis of the classroom videos, Greeno provides a theoretical basis for analyzing classroom interactions. He advances the notion of empowering students by positioning them with the authority, accountability, and competence to problematize issues and reconcile differences among themselves. This commentary focuses on the different aspects of representational competence that the students were grappling with in the lesson analyzed and that students need to develop in order to be skilled in mathematical and scientific reasoning.
