Abstract

The objective of this research is to identify (The Impact of the Virtual Laboratory in developing the skills of Laboratory Experiments, among Second-Year Secondary Students in Chemistry in Lahj Governorate). To achieve this, the research used an experimental Method, quazi-design which relied on two Equivalent groups which included (40) students at the second-grade secondary students at Amr ibn Al-Aas School in Al-Madharaba and Ras Al-Ara district, Lahj Governorate.

1- There are statistically significant differences at the significance level (0.05 (and between the average scores of the experimental group students and the control group students in the post-test of the laboratory experiments in favor of the experimental group.There are statistically significant differences at the significance level (0.05) between the average scores of the pre and post- test of the lab testing of the students of the experimental group taught using the virtual laboratory in favor of the post - test.
