Argomentazione e analisi del testo nelle didattiche disciplinari

In this paper I discuss a workshop that I co-taught within the POT-PLS project proposed by the University of Bologna in 2020. The aim of the workshop was to instruct mathematics and physics teachers on how to integrate methodological tools from physics and philosophy in order to improve teaching and learning. We focused in particular on the analysis of some widely used textbooks, and we selected as a case study for the analysis some pages related to the properties of the parabola. The workshop highlighted some deficiencies in the use of arguments in the presentation of the knowledge related to the parabola. In this paper we report this analysis and provide some suggestions concerning in particular the use of arguments in teaching and learning physics and mathematics.
