The Effectiveness of Using Blended Learning in Teaching Geometry on Achievement and Developing Geometrical Thinking with Second Intermediate Graders / Ibrahim Mohamed Ali Al-Ghamdi

This study aimed to identify the effectiveness of using blended learning in teaching geometry on developing geometrical achievement and thinking with second intermediate graders.It was applied on a sample consists of (55) students from second intermediate graders at Al-Baha Directorate of Education. The first class consists of (27) students represent the experimental group, and the second is (28) students represent the control group. The study was applied in the first semester of the academic year 1434/1435 H. The researcher prepared achievement test and test of geometrical thinking. The study reached to that there are statistically significant differences at (0.01) in favor of the experimental group in achievement at all level. Also, the study reached to experimental group superiority in the test of geometrical thinking as a whole, and in each level of its levels at (0.01) with high effect size. Moreover, there is statistically significant positive correlation at (0.01) among geometrical achievement and thinking.
