The objective of the study is to discuss the effects of writing activities with educational purpose on the academic achievements of primary school students. Data of the study is provided by examining relevant books and scientific articles as documents according to descriptive analysis approach. In qualitative research, examination of documents may be used individually as a data collection method. Document examination includes analysis of written materials involving information on events and facts intended to be researched generally, and they’re more preferred as compared to observations and interviews, since they are faster, more economical and easier to conduct. It is observed that experimental groups have higher success rates in the studies performed related to writing activities having an educational purpose. Specifically in semi-experimental studies, although there is not a meaningful difference in the pre-test results of the experimental and control groups, post test results show that experimental groups performing writing activities for studying are generally more successful. As the students performing learning purpose writing activity shall be by their self, he/she will think in order to solve the existing problem, and he/she will use their skills and especially above all, he/she will start using his/her intelligence without needing explanation from other people and thus he/she will learn how to use their intelligence. After the lectures are given, asking the students to perform writing activities to enhance their learning may enable the students who are performing the activities to structure the subjects they have written in their minds correctly and thus for their learning to become permanent. Since primary school students are thought to be better motivated due to their age, it is projected that using writing activities for learning objectives may have positive effects on their academic achievements
