Comparing the old and new 6th - 8th grade mathematics curricula in terms of Van Hiele understanding levels for geometry

Abstract

Abstract This study was conducted with the aim of comparing the behaviors and attainments related to the plane geometry in the old and new 6th - 8th grade mathematics curricula (MC) in terms of Van Hiele geometry understanding levels. With this purpose document analysis method was used. In the study, the levels of behaviors and attainments in the old and new 6th – 7th grades MCs were determined according to Van Hiele theory. As a result of the study, it was found that although the number of attainments in the old MP related to plane geometry decreased in the new one, the percentage of levels of some of the topics was increased. Moreover it was found that both the old and new MCs involve higher order behaviors and attainments for 6th grade such as deductive reasoning.
