The Effect of Post Codes Activity on Students’ Success on Unit of Permutation

In this study, it was aimed to determine the effect of activity-based teaching methods to students’ achievement on “Permutation” unit in elementary program. Our study was carried out on in elementary school which is located in Sakarya in first semester of 2010-2011 academic years. The sample composed of total 72, 7th grades students. Two intact groups were assigned randomly as control (36) and experimental group (36). During four weeks, while permutation subject was taught by activity-based teaching methods in experimental group, it was instructed using traditional approach to teaching in control group. Data was gathered using an achievement test of permutations with 20 items developed by the researchers. Mathematical achievements were taken into consideration when creating the experimental conditions and making statistical analysis. The data were examined by independent t-test and ANCOVA. The findings of the research showed that achievements of both groups increased significantly after the study. But achievements scores in experimental group are statistically significant difference. As a conclusion, activity-based teaching methods can be efficiently implemented in 7th classes and helped students improve meaningful learning.
