for the modified van iele theory were found to be 2_. 22 and 1.45 using the 3 of 5 and 4 of 5 criteria respectively.
A significant relationship was found be~ween the students' assigned van Hiele levels and their proof-writing·
.achievement. No sex-related differences w~re found between
··students 1 van Hiele 'levels and their proof-writing achievement •.
