While the instruction following the van Hiele theory used the curricula, CMPís Shapes and Designs and Key Curriculumís Discovering Geometry: An Inductive Approach, the comparative groupís instruction used Scott Foresmanís Middle School Math Course
I. Two hundred seventy-three sixth-grade mathematics students Ė 123 in the control group, and 150 in the treatment group Ė were involved in the study.
The researcher employed a geometry test, Van Hiele
Geometry Test (VHGT), used to measure studentsí geometry performance and a questionnaire, Course Interest Survey (CIS), used to measure studentsí motivation toward the geometry instruction. The VHGT and CIS were both administered to the students by the researcher before and after a five-week period of instruction during a single class period.
The paired samples t-test, the independent samples ttest, and ANCOVA with Š = .05 were employed in the analysis of the data. The study indicated that there was no statistically significant difference with respect to studentsí performance between the treatment and control
groups, and that there was a statistically significant difference in regard to studentsí motivation between the two groups favoring the treatment group instructed with the van Hiele theory based curricula. However, no statistical
difference was indicated by gender in regard to studentsí performance and motivation.
