Conference publicationsAbstractsXIX conferenceA study of Van Hiele Levels of Geometric Thinking at the Middle Basic Education in Nasarawa State of NigeriaMathematics Department Nasarawa State College of Education, Akwanga +234836101079, E-mail: mailegah@yahoo.com 1 pp. (accepted)This was an empirical study which used the quasi-experimental design to investigate the attainment of Van Hiele’s 1st, 2nd and 3rd levels of geometric thinking by pupils at Middle Basic Education level in Nigeria. A 38 multiple-choice geometric test achievement designed on Five Geometric Concepts: Circle, Square, Isosceles Triangle, Congruence and Parallel lines, and which were validated and tested for reliability (r = 0.73), was used to collect data for the study. Pre and posttests were administered to (randomly selected) 60 primary-six pupils to determine their levels of Geometric thinking at the Van Hiele’s 1st, 2nd and 3rd levels. Two research questions and two research hypotheses designed to guide the study were statistically tested using the following statistical techniques: Variance, Markov Chain, Co-variance, Kuder-Richardson (K-R(21)) Formular and linear regression. Results indicated the pupils were at mostly level 1 of Van Hiele’s geometric thinking. A significant difference (P≤0.05) was observed in students achievement. Out of many factors affecting students performances, teaching using Van Hiele Model contributed about 17% which is significant to students’ performance. On the strength of the findings from this study, implications and some recommendations are offered and areas for future research are specified.
