Application of Problem Teaching in Lower Grades of Primary Schools and its Impact on the Improvement of Mathematical Knowledge of Students

In this paper the application of problem teaching mathematics and respect its characteristics was investigated in the lower grades of primary school, in order to demystify its role and importance in enhancing the educational and functional effect. The research was done in the period from September to December 2015, by testing students of fourth grade in five elementary schools. Statistical analysis of the selected groups has shown there is no statistically significant difference between groups, and the test normality of distribution was done using the Kolmogorov-Smirnov and Shapiro-Wilk test. Analysis and comparison of results before and after the experimental program, indicates a significant improvement in students' knowledge and mathematical competencies applying the methodology that has been implemented.
