@article{2015,title={TEACHING FACTORIAL AND PERMUTATIONS WITH ENCRYPTION ACTIVITIES AND ITS EFFECT ON STUDENT ACHIEVEMENT},abstractNode={This study’s aim is using activity-based teaching method for teaching and carried out to determine the effect of student achievement in comparison to the traditional narrative which learning area is present in elementary program of "Factorial, Permutations" units. In this study, factorial and practice-based educational activities for teching permutations.were made and prepared on the basis of the coding efficiency. To create social applications is an important source of new information. Didactic theory argues that the effectiveness of the social activities in mathematics. Creating encryption efficiency benefited from this feature of a didactic transformation for his study. This study, studying in a primary school in the district of Sarıyer in İstanbul, which was applied to 72 students in 7th grades in the first semester of 2013-2014 academic year study. When creating the experimental conditions mathematical achievements of both subjects were taken into consideration in making statistical analysis. Data was associated with the t-test and analyzed. The findings of the study showed that significantly increase their success in the treatment of post-course test both the control group. However, the control group and the experimental group "Factorial Permutations" between their performance has been observed that there is a significant difference in the unit. When the results such as activities performed during the study consolidate students’ ability to reach concepts related with the subject and their existing knowledge are considered, it is seen that these activities can be used in various stages of a lesson such as getting attention, while lesson and evaluation.},author={Elif BAHADIR},year={2015},journal={The Journal of Academic Social Science Studies}}
