The Effect of Laboratory Experiments on the Upper Basic Stage Students Achievement in physics.

This study investigates the effect of laboratory experiments on grade ten students’ achievement in physics. It answers the question: Is there any effect on the tenth grade students( male and females discretely ) achievement that can be attributed to laboratory experiment? The sample of the study consisted of 130 Jordanian students. The experimental group students were taught physics in conjunction with laboratory experiments for forty five days. A thirty multiple choice item achievement test was designed to measure the students achievement .The study showed that the experimental group students achievement was higher than that of the control group students. The researcher recommends that(1) it is necessary to use the laboratory experiments in teaching science ,in general, and physics in particular, (2) the teaching schedule should include weekly classes for laboratory experiments in science, because this greatly enhances the student achievement in such topics .(3) Further similar studies involving different school stages and science branches like biology, chemistry and geology should be carried out. Key words: lab experiments , students achievement . science , physics , science teachin
