Effect used the virtual lab of achieve science for physics on first class secondary students

Abstract

The aim of the research is to reveal the importance of the virtual laboratory and its impact on the educational achievement of the first grade students of the intermediate stage. A number of hypotheses were developed to verify the access to the research objective and to analyze the data using the appropriate statistical methods. There was a statistically significant difference in the achievement of their members in physics and for the experimental group, indicating that the use of the laboratory has a positive effect on the educational attainment of the student level. The research community includes 40 students of the first medium, randomly chosen, divided into two experimental groups, with 20 students per group. The same sample was selected from 25 teachers. A questionnaire was distributed to physics teachers from different schools The researcher tested the achievement of science in physics and used the measure of strength of observation, the total behavioral goals are (8) and the test of physics are (8) test paragraph varied between the tests of tests and thematic test A teaching plan has been prepared on five of the lessons in the second chapter of the methods that require conducting experiments such as measuring the solid and liquid body mass and density of each and preparing the virtual lab through the use of internet sites and preparing the laboratory for experiment. Several statistical methods were used to analyze the search results:The standard deviation and the arithmetic mean of the experimental and control group marks on the strength scale of observation and the achievement tests of physics. And the use of T-test for two independent sample to test the validity of research hypotheses. The validity of the tool was tested by presenting it in its preliminary form to a group of arbitrators in the field of teaching physics. Stability of the collection tests was examined using the test-retest method The analysis of the results showed that the experimental mean of the experimental group was higher than that of the control group and that the proportion of teachers who support the use of the virtual lab is greater than the percentage of teachers who do not support its use There was no statistically significant difference between the experimental and control groups in the development of the observation force in their individuals using the tribal and remote tests, indicating that there is no role for the virtual laboratory in developing the observation power of the students. In the light of the results of the research, the researcher made a number of recommendations to take advantage of the technology of virtual laboratories, especially for experiments that lead to risks to the student when they are conducted and the student has no previous experience And prepare cadres of specialists to establish training courses for teachers and the creation of virtual sites on the public Internet sites
