The current research problem was identified in the presence of a decline in the knowledge and performance level of the fourth Grad students of the Administrative Information Systems at the Higher Nile Institute for Commercial Sciences and Computer Technology in Mansoura in the skills of operating and using computer networks, and this was shown through the exploratory study that was applied to students to show their knowledge level towards the skills Operation and use of computer networks. The research aimed to design virtual networking lab in a three-dimensional to develop a set of skills for operating and using computer networks in the study sample, and this three-dimensional lab is based on the second life SL, in light of the proposed design criteria for the three-dimensional virtual lab environment, which were identified in (19 standards, 242 indicators) And the three-dimensional virtual lab was designed in the light of the developed educational design model based on the Mohamed Desouky model for educational design for widespread learning. The list of skills for operating and using computer networks has been identified in (28 main skills, 263 sub-procedures), and the current research sample was limited to J (40 male and female students) from the fourth year students of the Division of Administrative Information Systems, and relied on the experimental design with two groups, one is experimental and the other is control, and the two measurement tools (achievement test and note card) were applied previously to the two groups, then the experimental group was subjected to learning using the three-dimensional virtual lab The proposal, while the control group underwent learning using the network lab available at the Academy, then applied the measurement tools (achievement test, note card, product evaluation card) on the two dimensions, and then performed the statistical treatment of the results of the measurement tools using statistical analysis SPSS v 23.0, then interpret and answer questions on the results of research and ensure the validity of hypotheses which proved the following: 1) There are statistically significant differences at the level (≤ 0.05) between the mean scores for the experimental group and the control group in the post-application of the achievement test in favor of the experimental group. 2) There are statistically significant differences at the level (≤ 0.05) between the mean levels of the pre and post application scores for the experimental group in the achievement test in favor of the post application. 3) There are statistically significant differences at the level (≤ 0.05) between the mean scores for the experimental group and the control group in the post application of the observation card in favor of the experimental group. 4) There are statistically significant differences at the level (≤0.05) between the mean levels of the pre and post application grades for the experimental group in the observation card in favor of the post application. 5) There is a statistically significant difference at the level (≤0.05) between the mean scores for the experimental group and the control group in the post application of the product evaluation card in favor of the experimental group.
