The research aims to identify the effectiveness of the strategy of filtering ideas in the achievement of physics material among students in the fourth grade (scientific section), and the researcher adopted the experimental approach of partial experimental design for two equal groups, as the researcher randomly selected Division (B) to represent the experimental group that will study physics according to the strategy of filtering ideas, and Division (D) to represent the control group that will study the same subject in the usual way, and the total number of students of the two groups (64) students; By (31) students in the experimental group, and(33) students in the control group; It was statistically rewarded among the students of the two groups In the following variables: (The chronological age is calculated in months, the previous information test, and the intelligence test Otis Lennon), and the researcher identified the subject matter in the subjects from the physics book for the fourth grade scientific, and then the researcher formulated behavioral objectives as the number of (200) behavioral objectives, As for the research tool, the researcher has built the achievement test, which consisted of (40) objective test items  of the choice of multiple four alternatives according to (the specifications table), and the validity, the coefficient of discrimination, difficulty and the effectiveness of alternatives and validity  were verified; Its validity  was verified in a half-partition method; The researcher used statistical means The results showed that the students of the experimental group outperformed the students of the control group, and in light of the results of the research, the researcher developed a number of recommendations and proposals that were mentioned in the fourth chapter.
