The objective of this research is to find the effectiveness of employing the augmented reality technology to development seventh grade students in chemistry at Gaza Strip, using elements 4D. The researchers used the quasi experimental approach to the applythis research, research sample was (93) students from the seventh-grade students. The research tool was an achievement test. The test was applied to both groups(experimental/control). The experimental group studied using augmented reality technique. The control group studied using traditional methods. The results showed that there were statistically significant differences between the average control and experimental group in the post-test favor for the experimental group, also the augmented reality technology achieved a high efficiency more than (1.2) according to the average gain of blacke in raising the level of students in chemistry subjects.
