The effectiveness of an educational website based on differentiated education for teaching geometry to develop some geometric proof skills for first year prep school students.

The current research aimed to identify the effectiveness of an educational site for teaching geometry based on differentiated education to develop some geometric proof skills among first-grade prep school students, the researcher used the experimental approach with a semi-experimental design. The educational site based on differentiated education and a group of (34) male and female students who studied in the traditional way. Rresults showed that there are statistically significant differences between the mean scores of the students of the control and experimental groups in the post application of the research tool represented in testing some geometric proof skills for the students of the first grade of middle school in favor of the experimental group. Holding training courses for mathematics teachers on how to teach using educational websites to teach mathematics using differentiated education.
