The aim of the current research is to identify (The impact of Edelson's model of analogical thinking among fourth preparatory students in Biology) and to verify the validity of the following hypothesis:
- There is no statistically significant difference at the level of significance (0.05) between the average scores of the experimental group students who studied according to the Edelson model and the average scores of the control group students who studied according to the usual method of analogical thinking in biology, the current research community is represented by the students of the fourth year of preparatory school in Al-Nomaniya Secondary School for Boys, which is affiliated to the Wasit Education Directorate, and the number of students was chosen intentionally, the number of students was (300), the research sample was chosen by simple random sampling. Class (16) represented the experimental group that was studied according to the Edelson model, where the number of students was (15) and class (11) represented the control group that was studied according to the usual method, whose number of students was (15) students. The experiment was applied in the first semester of the academic year 1020-2021. It took (10) weeks, with a class per week for each group, and the academic content was determined in the first five semesters of biology, the behavioral objectives were analyzed, amounting to (170) behavioral objectives in the light of Bloom's classification of the cognitive domain according to levels (remember, understanding, analysis, application, installation, evaluation) to achieve the goal of the research, the researcher prepared (40) items to measure analogical thinking, which are situations that each item contains two alternatives and with weights (zero one). After applying the Eta square equation, the impact size was (0.77), therefore, the impact size of Edelson model in the Analogous Thinking Test has a high impact in favor of the experimental group, the average ranks of the experimental group were 22.50 and the total ranks of 337.50, while the average ranks of the control group reached 8.50 and the total ranks of 127.50, where the value of the calculated Mann Whitney test was 7.500 and the Mann and Tenney tabular value 23, with a degree of freedom of 28, which means that it is significant at a significance level of 0.05 in favor of the experimental group.
