The objective of the current research is to design scientific concepts and problem-solving skills in science for elementary sixth graders, through designing a virtual class. To verify this, the researcher has designed measurement tools in research: testing scientific concepts and testing problem-solving skills. The researcher followed the descriptive survey curriculum to prepare the theoretical framework for the research and followed the experimental curriculum to verify the effectiveness of the virtual classroom in developing scientific concepts, and the skills of solving problems in science for students in the sixth grade. The researcher developed the virtual class according to the Abdul Latif Al-Jazar (2014) model of design and educational development. She also followed the semi- experimental concept of the two groups with pre/post measurements. She applied experimental processing and measurement tools in the research for a sample of primary sixth grade pupils numbering 70 pupils from Mansoura College International Language Schools, Dakhlia. The sample was randomly selected and divided into two researching groups. By analyzing the data statistically, the researcher came up with the results of the research: statistical difference indicated at the level of (≤0.05) among the average grades of the two experimental groups, the first experimental group studied through the registered virtual class, and the second experimental group studied through the direct virtual class, in the post applying of both the scientific conceptual test and the problem-solving test for the second experimental group studied through the direct virtual class. There is also a correlation between the remote application of the post scientific conceptual test and the post applying of the problem-solving test.
