The purpose of the research is to identify the impact of the Pairs Check strategy in the achievement of students in the fourth grade in physics. The researcher adopted the empirical research method as a methodology for conducting the current research. It includes an independent variable (Pairs Check) and the usual method (and a dependent variable) The results of the study were calculated according to the Pairs Check strategy and the average scores of the students of the control group who study according to the usual method in the test. In addition, the researcher prepared an achievement test consisting of (50) paragraphs according to the behavioral objectives set According to the relative importance of the content. The researcher investigated the cycometric characteristics of the test after conducting the experiment on the research sample in the academic year (2018–2019), which lasted for 8 weeks.
