Van Hiele (VH) levels of geometric thinking were investigated on a
sample of 207 of mathematics education learners at Alquds Open University
(QOU). The results showed that 70.6% of them were within the third level
of (VH) geometric thinking or below, while 29.4% were within the fourth
and the fifth levels. This indicates that most of (QOU) math learners were
performing at a lower (VH) level than they should be.
The second objective of this study was to determine the effect of Research-
Based Strategies of teaching and learning on raising the (VH) geometric
thinking. A group of 18 (QOU) mathematics education learners studied a
geometric course according to Marzano’s Research-Based Strategies. The
results of the learners improved significantly which indicated the effectiveness
of employing these strategies in raising learners’ thinking levels of (VH).
Accordingly, it is recommended that curriculum planners and developers,
educators, supervisors and policy makers take the Research-Based Strategies
into consideration when designing and developing the syllabus.
