After some general considerations about the new educational needs particularly for the renewal of Algebra teaching, we give some hints about our ‘ArAl project’ concerning early algebra and we sketch the complex methodology of work with teachers. Then we analyse a teacher’s transcript about a classroom discussion on a problem situation where a joint vision of the couple ‘function and inverse function’ is promoted. We focus on pupils’ behaviour in detecting functional relationships and in facing their different representations, highlighting the teacher’s reflections step by step. Finally, we discuss how comparisons of teachers’ ways of acting in the class and more generally their new conceptions may influence them.

Abstract
After some general considerations about the new educational needs particularly for the renewal of Algebra teaching, we give some hints about our ‘ArAl project’ concerning early algebra and we sketch the complex methodology of work with teachers. Then we analyse a teacher’s transcript about a classroom discussion on a problem situation where a joint vision of the couple ‘function and inverse function’ is promoted. We focus on pupils’ behaviour in detecting functional relationships and in facing their different representations, highlighting the teacher’s reflections step by step. Finally, we discuss how comparisons of teachers’ ways of acting in the class and more generally their new conceptions may influence them.Pubblicazioni consigliate
