Absztrakt (kivonat)
The evolvement of some geometrical concepts, such as parallel and per- pendicular has been studied in a developmental teaching experiment in class four whose aim was to put the model of geometry teaching according to van Hiele into practice. Our research question is how lower primary geometry teaching in Hungary, particularly teaching the concept of parallel and perpendicular is related to the levels formulated by van Hiele. Moreover to what extent are the concrete activities carried out at these levels effective in evolving the concepts of parallel and perpendicular. Our hypothesis is that in lower primary geometry teaching (classes 1–4) only the first two stages of the van Hiele levels can be put into practice. By the completion of the lower primary classes transition to level 3 is not feasible. Although the set of concepts are evolved but there is not particular relationship between them. The logical relationships between the characteristics of a shape are not really recognized by children. They are not able to infer from one characteristic of a shape to another.
