المستخلص The aim of the current research is to investigate the effectiveness of a constructive strategy based on the theory of variation in correcting misperceptions of chemical concepts and developing cooperative investigation skills among secondary school students, and to achieve this the researcher used the experimental approach with a semi-experimental design, and the test of misperceptions of chemical concepts was prepared, and the observation card of cooperative investigation skills and applied to the research sample consisting of (40) students of the first grade of secondary school in two schools, one of which represents the control group in the management of Girga educational and the second represents The research resulted in statistically significant differences at the level of (α = 0.05) between the average ranks of the experimental and control groups in the post-application of the test of misperceptions, and the existence of statistically significant differences at the level of significance (α = 0.01) between the average ranks of the experimental group scores in the pre- and post-measurements of the test of misperceptions, and the existence of statistically significant differences at the level of (α = 0.01) between the average ranks of the experimental and control groups in the post-application For the survey skills note card, And the presence of statistically significant differences at the level of significance (α = 0.01) between the average ranks of the experimental group scores in the pre- and post-measurements of the cooperative inquiry skills observation card.In light of these results, a number of recommendations and proposals related to research variables were reached.Keywords:A constructive strategy based on the theory of variance -cooperative investigation skills - Chemistry in the first year of s |
