REASONING IN PRIMARY MATHEMATICS – AN ICT-SUPPORTED ENVIRONMENT

The public view on mathematics is often reduced to and seen as ‘only calculating’. General mathematical competencies like exploration or discovery are hardly considered. One reason therefore is a lack of didactical concepts of how to promote reasoning skills together with an instrument to assess these competencies. Another reason is, that some children rarely get the chance to act in an explorative way because they have difficulties in calculating. The aim of the project KLIC (Kinder lernen in computergestutzten Lernumgebungen) is to support the development of general mathematical competencies, in particular exploration and discovery, of all children. We currently develop and analyze self-differentiating tasks regarding their suitability to support argumentation and we analyze in what way and with which specific aims ICT can support the mathematical learning processes.
