Abstract

The research aimed to reveal the effectiveness of E-learning environment in developing geometric construction skills in mathematics among 10th graders in Palestine. and the research followed the quasiexperimental curriculum by designing one experimental group (Pre- post). And the researchers built the study tools represented in a cognitive test and an assessment card to measure geometric construction skills, which were applied to a sample of (22) 10th grade female students from Ali bin Abi Talib Secondary School for Girls. The research concluded the effectiveness of the electronic educational environment in developing geometric construction skills, as the black gain rate was (1.37), as well as the existence of statistically significant differences at the level of significance (alpha = 0.05) between the average scores of the 10th grade students in the cognitive test of geometric construction skills before and after the application in favor of the post application, there were also statistically significant differences at the level of significance (alpha = 0.05) between the mean scores of the tenth grade students in the assessment card for geometric construction skills before and after the application in favor of the post application. The research recommended employing electronic learning environments in teaching geometric constructions، and working on holding training courses in e-learning for teachers.
