The effect of the Cox and Macialas model on the achievement of fifth-grade literary students in Arabic language

The effectiveness of the effect of the Cox and Macialas model on the achievement of fifth-grade literary students in Arabic language.. To achieve the goal of the research, the researcher developed a null hypothesis, which is as follows1- There is no statistically significant difference between the average scores of the students of the experimental group taught according to the Cox and Macialas model and the average scores of the students of the control group who study according to the usual method in the achievement test.As for the research sample, it was intentionally selected from the research community and it consisted of students of the fifth literary grade in (Nile Preparatory School for Boys) in the city of Mosul from the academic year (2021-2022), and its number reached (61) students distributed into two experimental and control groups, at a rate of (31).) students for the experimental group that studied according to the model of Cox and Macialas, and (30) for the control group that studied in the usual way.The researcher used the experimental method and conducted the process of equivalence between the members of the two research groups in a number of variables, which included: the chronological age calculated in months, the degree of the Arabic language subject for the previous year, the academic achievement for the previous year (general average), the intelligence quotient, and the critical thinking test.To achieve the goal of the research, two tools were required: the first is the critical thinking test as a research tool, and the second is an achievement test. The two tests were characterized by honesty and stability.After preparing the teaching plans and the two tools, the experiment was applied in the first course of the academic year (2021-2022) on Thursday 11/11/2021, and it continued for a full course and ended on Tuesday (1/1/2022), as the achievement test was applied on Thursday. Corresponding to (20/1/ 2022), on the two research groups, and after data collection and statistical analysis, the researcher came up with a number of conclusions, recommendations and suggestions, including:1-There is a statistically significant difference between the two groups in the critical thinking test and in favor of the experimental group with the highest arithmetic mean, which was studied according to the Cox and Macialas model..2-Using the (Cox and Macialas) model in teaching literature and texts in the fifth literary grade by the Ministry of Education because it is commensurate with the content of the scientific material included in the curriculum decided by the Ministry of Education Accordingly, the researcher recommends and suggests the following :3-The effect of the (Cox and Macialas) model in developing the complex thinking of undergraduate students in the Arabic language subject.
