Abstract
Interactive graphics systems for geometric construction at school allow the teacher to design microworlds in which the graphic‐constructional competencies of the student can be qualified ('reduction of the graphic‐constructional barrier'). Ideal typical possibilities of the design are given by the modification of the menus and by the supply of graphic‐constructional finished or semi‐finished products for a direct manipulation or completion. Microworlds designed with the Cabri‐Géomètre for the secondary level I are presented, which adapt the tool to learning groups and to constructional‐geometric complexes of problems as well as to single problems.Keywords
