Students’ geometrical constructions and proving activities: A case of cognitive unity?
Students’ geometrical constructions and proving activities: A case of cognitive unity?
Geometrical constructions (whether with paper and pencil or with appropriate software) are widely considered to be a suitable vehicle for secondary school students to gain experience of proof and proving. It is also recognised, however, that there can be a tension between the practical aspect of physically carrying out a geometrical construction and the theoretical aspect of constructing the related proof. This paper reports on data from a teaching experiment in which Grade 9 students worked on a series of challenging geometrical construction problems. Analysing the data through the lens of cognitive unity, we report on whether, or to what extent, geometrical constructions in particular encourage the uniting of student conjecture production and proof construction. Our analysis suggests that this is not automatic.

Abstract
Geometrical constructions (whether with paper and pencil or with appropriate software) are widely considered to be a suitable vehicle for secondary school students to gain experience of proof and proving. It is also recognised, however, that there can be a tension between the practical aspect of physically carrying out a geometrical construction and the theoretical aspect of constructing the related proof. This paper reports on data from a teaching experiment in which Grade 9 students worked on a series of challenging geometrical construction problems. Analysing the data through the lens of cognitive unity, we report on whether, or to what extent, geometrical constructions in particular encourage the uniting of student conjecture production and proof construction. Our analysis suggests that this is not automatic.
