Abstract
Problem solving, i.e. the ability to model real life situations in mathematical terms and to solve the problems connected to them, plays an important role in teaching and learning Mathematics to and by students at every level of education and it is one of the basic skills for the education of citizens. By learning problem solving in Mathematics, students acquire ways of thinking, creativity, curiosity, collaborative skills and confidence in unfamiliar situations, from which they will benefit also outside the Mathematics class. The use of digital technologies helps in both representing and exploring mathematical tasks. Technologies also provide a range of tools and opportunities to structure and support learning environments in which students continually interact to build knowledge and solve problems. The national PP&S  Problem Posing & Solving  Project of the Italian Ministry of Education aims to enhance the teaching and learning of Mathematics and Informatics using new methodologies and technologies. One of the methodologies is problem solving through the use of an Advanced Computer Environment (ACE). An ACE is a system that allows to perform numerical and symbolic calculation, make graphical representations in 2 and 3 dimensions and create mathematical simulations through interactive components. Moreover, it is able to support students in reasoning processes, in the formulation of exit strategies and in the generalization and readaptation of the solution in different contexts. The goal of this paper is to discuss the results of an immersive workshop, entitled "Mathematical Exploration with Problem Posing and Solving", involving 50 secondary school Maths teachers, who were invited to reflect on the role of an ACE in learning and teaching Mathematics through problem posing and solving. During the workshop the problem solving methodology used in the PP&S project and an example of a contextualized problem solved with the use of an ACE were presented. The results emerged from the analysis of the questionnaires (initial and final) completed during the workshop and from the study of the works delivered by the teachers, who were asked to design a problem, its resolution and generalization through the use of an ACE. These results are useful to understand teachers’ reflections on the methodologies proposed and on the impact of new technologies on teaching.File  Dimensione  Formato
