This study aimed to investigate the effect of the van Hiele model in Geometric Concepts Acquisition, and the attitudes towards Geometry and learning transfer of the first three grades students in Jordan. Participants of the study consisted of 60 students from the third grade primary school students from the First Directorate, Amman, in the academic year (2015-2016) and they were divided randomly into a control group and an experimental group. To achieve the objectives of the study, the teacher's guide was prepared for the unit of Engineering and Statistics taken from the text book of Mathematics of the third grade in accordance with the model of Van Hiele, and the preparation of test engineering concepts which consisted of 17 questions of multiple choice, in addition to the scale of attitudes towards engineering and test learning transfer effect. Data were analyzed using ANCOVA and results were as follows: there are significant differences between the average performance of each of the two groups of the study on the scale of Geometric Concepts acquisition in favor of the experimental group taught by using the Van Hiele model. And there are significant differences between the average performance of the two groups on a scale of attitudes towards geometry in favor of the experimental group taught by the Van Hiele model. There are significant differences between the average performance of each of the two groups on the learning transfer test in favor of the group taught by the Van Hiele model.
