The effect of a strategy to get the moon on the achievement of middle school students in geography

The current research aims to know (the effect of BOSSE strategy on the achievement of middle school students).To achieve the goal of the research, the researcher chose the experimental method, and to achieve the goal of the research, the researcher formulated the following hypothesis:1. There is no statistically significant difference at the level of significance (0.05) between the average scores of the experimental group students who will be taught according to the strategy of getting the moon and the average scores of the students of the control group who studied according to the usual method of achievement.The current research sample consisted of (46) female students of the fifth literary grade for the academic year (2020-2021), distributed into two equal experimental and control groups, and the experimental group was studied according to the strategy of obtaining the moon, and the control group according to the usual method.In her tool, the researcher prepared an achievement test for geography of a multiple-choice type, and the researcher extracted the coefficient of difficulty and discrimination for its paragraphs, and its stability was calculated using the Facronbach method and its stability coefficient was (0.89), and the second tool was a test of visual thinking, and the stability was calculated using the Facronbach equation and Its stability was calculated using the retest method and using Pearson's correlation coefficient, and its discriminatory strength and stability were extracted using Cronbach's alpha method.
