The aim of this study is to analyze the impact of step-by-step educational comic book behavior of the elementary school students and their reading levels on their learning competencies. To this end, qualitative research with focus group and deep interviews was conducted with students on different reading levels. During their repetitive reading activities, the students tended to use various educational comics within the same subjects area on their corresponding reading levels. Such behavior led the students to further read other books than comics in the similar subjects areas, and by doing so, the books acted as an important reference to the students' class materials. It was found that the students' such behavior has positive impact on the improvement of their learning competencies. It is hoped that this study will be supportive to develop self-study methods and effective reading guidance plans by improving the usage of educational comics.
