Özet:

The problem-solving ability is an important thinking ability that is needed to be given to individuals in the age we are in. Therefore, studies and practices in the direction of providing the ability to solve problems in the educational process and the transfer to the daily life to be compatible and useful to the society in which the individual is able to perceive and solve problems are very important. With this research, the first-class fourth-class social knowledge course "Marmara Three-Step Cognitive Decision Process Model" aimed at determining the impact of low academic success fourth-class students on problem-solving skills. In the study, the only group of weak experimental patterns were used pre-test-sontest patterns. As an easy-to-accessful sample of the study group, the academic success of 26 (18 men-8 girls) selected from the fourth class of a primary school located in the district of Istanbul is the low fourth class student. The Social Information Academic Success Test, which was developed by the researcher himself, was implemented while the student’s selection was carried out, the teacher’s opinions were taken and the e-school notes of the fourth-class students were studied. To be able to measure the level of problem-solving skills of students, the application was implemented as a estest at the beginning of the application "Problem-solving Reserve for Children at Primary Education Level" developed by Cold, Cloud-Serin and Respect (2010) as an estest at the end of the application. Four weeks after the application of Sontest, the same measurement tool was applied as a durability test. The trial group has been used to determine the difference between the pre-test and estest points and the trial group’s final test and durability test points. The implemented "Marmara Three-Step Cognitive Decision Making Skills Development Model" has been found to have a low academic success of fourth-class students, having an impact on problem-solving skills and this effect is permanent. At the end of the study, the results obtained from the statistical analysis are discussed.
