The thesis presented by the student Muhammad Mishaal Rahim aimed to know (The effect of an educational bag based on the virtual laboratory on the achievement of first-year middle school students in chemistry and their clever thinking) To achieve the two objectives of the research, the researcher set the following two null hypotheses: There is a statistically significant difference at a significance level of (0.05) between the average scores of students in the experimental group who study according to an educational bag based on the virtual laboratory, and the average scores of students in the control group who study according to the usual method in the academic achievement of chemistry There is a statistically significant difference at a significance level of (0.05) between the average scores of students in the experimental group who study according to an educational bag based on the virtual laboratory, and the average scores of students in the control group who They study according to the usual method of critical thinking. The researcher relied on the experimental design with partial control as a research design. The researcher randomly selected a sample of first-year middle school students at Al-Qadisiyah Intermediate School for Boys. The study sample consisted of (66) students, including two experimental groups and a control group. Using the random drawing method, the researcher rewarded the research groups in the variables (chronological age calculated in months, intelligence test, parents' achievement, critical thinking test, previous year's average). The experiment began on Sunday (11/5/2023 AD), and ended on Thursday (4/18/2024 AD), on the two study groups. For the purpose of statistically processing the data, the researcher used the statistical package (spss). The thesis concluded that the educational bag based on the virtual laboratory had a significant impact on increasing students' achievement in chemistry for the first middle school grade. Progress in the level of critical thinking among students Meeting the needs of students in the first middle school grade in chemistry and filling the gap in their experiences
