The current research aims to identify “the effect of the group punctuation strategy on the acquisition of Arabic grammar among fifth-grade female students.” To achieve the research goal, the researcher chose the experimental method, the design with partial control, and the post-test for the research group. After that, the research community was determined, and the research sample consisted of (60). A female student from the fifth grade of primary school in (Shu`a Al-Ilm Primary School) was intentionally chosen by the researcher from the schools affiliated with the Baghdad Education Directorate, Al-Rusafa II. The sample was distributed randomly into two groups (experimental and control), with (30) female students in the experimental group and (30) female students in the control group. The researcher rewarded the students of the two research groups in the following variables: (chronological age calculated in months, the academic achievement of the parents, and the final grades of the Arabic language subject for the previous academic year). The researcher studied the students of the experimental group using the group numbering strategy, while the students of the control group studied in the usual way, and determined The researcher took the scientific material included in the experiment from the Arabic grammar book for the fifth grade of primary school for the academic year 2023-2024. The researcher formulated the behavioral objectives, and in the end their number reached (45) behavioral objectives. She prepared teaching plans and presented examples of them to the experts. The researcher prepared a post-test consisting of (25) items distributed across the first three levels of Bloom’s classification to represent the research tool. After applying the experiment, the researcher applied the tool to the research sample. The researcher used the Social Statistical Package (SPSS) for statistical methods, and the results showed that the female students of the experimental group outperformed the female students of the control group in the achievement of the Arabic grammar subject, and the differences were statistically significant between the students of the two groups. One of the most important conclusions was that the group punctuation strategy proved effective in raising the level of achievement of the Arabic grammar subject for fifth-grade primary school students compared to the usual method. The researcher recommends adopting the (group punctuation strategy) ) in teaching Arabic grammar, and in continuation of the research, the researcher proposes a study similar to this study on other academic stages and other variables.
