Abstract
This paper introduces discursive tuning as a new commognitive notion for analyzing how students engage with a digital environment and react to unexpected responses they receive from it. Discursive tuning provides a theoretical tool for describing changes in students’ discourse in response to commognitive conflicts arising during their activity with the digital environment. We discuss the notion’s analytical capacity through some episodes from a study in which upper secondary students interact with the dynagraph of the function f(x)= 1/x. Our analysis identifies specific cases of discursive tuning that occur when students attempt to include into their discourse narratives that are consistent with the behavior of the dynagraph or with canonical mathematical discourse. These cases illustrate how discursive tuning provides insight into how students can resolve commognitive conflicts in productive ways.
期刊介绍:
The Journal of Mathematical Behavior solicits original research on the learning and teaching of mathematics. We are interested especially in basic research, research that aims to clarify, in detail and depth, how mathematical ideas develop in learners. Over three decades, our experience confirms a founding premise of this journal: that mathematical thinking, hence mathematics learning as a social enterprise, is special. It is special because mathematics is special, both logically and psychologically. Logically, through the way that mathematical ideas and methods have been built, refined and organized for centuries across a range of cultures; and psychologically, through the variety of ways people today, in many walks of life, make sense of mathematics, develop it, make it their own.
