The present study attempts to identify The application of the four stages of learning (Good Lavoies model) on the ability of the learner in the extent of the concept’s knowledge, comprehension and application of the fifth grade primary students. The research community has been identified with fifth-grade primary students in Al-Furatin School. The elementary school of the General Directorate of Education, AlKarkh, the first for the academic year (2020 - 2019), where the researcher used the experimental design with two experimental and control groups, one of which controls the other partly and from the post-test subjects to acquire scientific concepts, and according to this design the sample was chosen. For the two research groups to be represented, as the number of the sample population reached (60) students and by random appointment, Section (A) was chosen to represent the experimental group and the number of its members (30) is taught according to the Good Lavoies' model, while Section (C) represents the control group and the number of its members (30). (A student taught according to the usual method, the two groups were rewarded in the variables of previous information, intelligence, and previous achievement in the science subject) The scientific subject was identified in the first, second and third units of the science book for the fifth grade of primary school, the experiment was applied in the first semester of the academic year (2019 - 2020) The researcher taught M. The two research groups themselves and teaching plans were prepared as they reached (24) plans for the experimental group, and similarly to the control group, behavioral goals were represented representing acquisition of the three units, and the number (72) targets represented by the three levels of acquisition (definition, discrimination and application), as for the research tool. The scientific concepts acquisition test was prepared consisting of (72) objective paragraphs of the multiple choice type, the validity of the tool was confirmed and proven using the Koder Richardson equation 20 for the concept acquisition test as it reached (0). The ratio indicates that the tool obtained high stability, and the results of the research using the second test of two independent samples showed the following: The experimental group students who studied according to the Good Lavoies' model outperformed the students of the control group that studied according to the usual method of testing the acquisition of scientific concepts. As the T value (calculated) reached (3, 75), while the tabular T value (2) reached at the level of significance. (0, 05) Thus, the null hypothesis was rejected, and through the results I concluded the The application of a model on the acquisition of scientific concepts for fifth-graders Good Lavoie elementary, and based on what the researcher recommended a number of recommendations, including the need to introduce modern models in the teaching of science because of its importance. In acquiring different concepts and training teachers of science subject in the use of modern models and how to prepare teaching plans, both before and during service, as the researcher suggested conducting more studies on different study materials and different levels of study and on other variables .
