Background:This study presents partial results from the project “A Study of perceptual apprehensive, operative apprehensive, sequential apprehensive, and discursive apprehensive for elementary school students (POSD)”, which was undertaken to explore gender differences and passing rate of van Hiele’s geometric thinking level.Materials and methods:The participants were 5,581 elementary school students randomly selected from 23 counties/cities in Taiwan.Results:This paper analysed the passing rate of van Heile geometric thinking of Taiwanese 1st to 6th graders, and studied the gender differences at different grades. The statement below shows the passed population and the passing rate.Conclusions:The conclusions drawn from this study were: (a) evidence supporting the hierarchy of the van Hiele levels, (b) students at different levels have different concepts of basic figures, and (c) for elementary school students, the passing rates of boys and girls have no significant differences in van Hiele’s geometric thinking level.
