The impact of using the Van Hiele model in developing geometric thinking levels among tenth grade students in Jordan

Abstract EN

-This study aimed to investigate the impact of the usage of the Van Hiele model in the development of geometric thinking levels among tenth grade students in Jordan.

The sample of the study was selected from tenth grade basic students in Amman schools.

Two hundred and forty students studying the mathematics course in the circle unit were divided into two groups: experimental (using the Van Hiele model) and the control (using the traditional approach of teaching).To achieve the objectives of the study, a test of geometric thinking in the unit of the circle was developed.

Validity and reliability of the test was verified.

The instructional material was also prepared in the circle unit for the students of the tenth grade using the Van Hiele model of geometric thinking.

Four mathematics teachers were trained on the model, and the content validity of the training material was verified.

The results of the study showed a statistically significant difference (α=0.01) between the two arithmetic means of the experimental and control agencies in favor of the experimental group that used the Van Hiele model in geometric thinking in general, and in sub-levels (visual, descriptive, logical), and the study showed no statistical significance difference (α=0.01) between the arithmetic means of male and female in geometric thinking, also the study showed an interaction between the model variable and gender variable in geometric thinking.
