An Influence on Engagement

Abstract

Several studies have investigated how the formation of informal conjectures,and the dialogue they evoke,might influence young children’s learning trajectories,and enhance their mathematical thinking(e.g.,Ponte, 2001;Ruthven,2001;Carpenter,Franke,&Levi,2003).In a digital environment,the visual output and its distinctive qualities can lead to interpretation and response of a particular nature.In this chapter,the notion of visual perturbations is explored,and situated within the data obtained,when the students engaged with investigative number tasks in a spreadsheet environment.
