AU - الحياوي، محب الدين محمود AU - حسين، عبد الكريم علي AB - The objective of the research was to identify the effect of the physical virtual laboratory contained in each of the following hypotheses have been formulated: 1) There is no statistically significant difference between the average scores of the experimental group studied using the virtual laboratory (and the control group studied using the traditional laboratory) in their lest convictions. Achievement of physics. 2) There is no statistically significant difference between the mean difference between the boost and pre - tribal application of the observation intensity of the students of the experimental group studied using the virtual laboratory (and the control group) studied the conventional laboratory). In order to achieve the objectives of the research and to verify the hypotheses. The researchers selected a random sample of reality (30) students from the department of physics at the faculty of education for pure sciences and divided in to the total of each group consists of (15) students. the first experiments study of physics experiments using the virtual drug prepared , the second is a control and study the experiments of physics using the traditional laboratory and the two groups in some of the variables that are believed to have effective on dependent variables, the researchers have used the computer software factory design laboratory sporadic physics experiments has also been preparing attest achievement, the physics and the preparation of the intensity of observation for the purpose of collecting research data and applied the experiment of the researchers at the beginning of the first month (10) of the year (2018). And continued until the end of the month (12) of the same year. That the student of the experimental group were receiving teaching experiments research in the computer lab, while the control group was the following results shown: difference between the experiment and control groups in the variable of achievement in physics as well as in the intensity of observation for the benefit of the experimental group.
