Some Considerations on the Use of Digital Environments in Learning Numerical Sets

Teachers are nowadays encouraged to use technological tools to engage students more and transmit topics in a simpler way. In addition, information science has become part of many curricula as a separate topic or as a part of other subjects like mathematics. This article will discuss how choosing a particular technological environment can reinforce misconceptions or ideas and how important the role of the teacher is in building a learning environment effective and epistemologically relevant. In particular, the focus will be on the impact that some technological environments have on learning numerical sets and arithmetic operations such as division, because these are studied in all school systems and levels, even if with different approaches and degrees of detail. The topic will be contextualized referring to the Italian school system (degree 10), but conclusions are general.
