The aim of this research is to develop a new practice to enhance the success and attitudes of the middle school students. With this in mind, the competition activity was designed by reading. The effect of this activity on secondary school students' reading comprehension success and attitudes towards reading was examined. In this research, quantitative methods and Quasi-experimental model is used. The research has been conducted with 5th grade students in a public middle school in the central district of Kütahya province, in 2018-2019 academic years. The implementation process of the research took 8 weeks. Lessons in the experimental group were taught using "I compete by reading" activity, and continued in the control group according to the Turkish lesson curriculum. Reading-Understanding Achievement Test and Reading Attitude Scale for middle school students were used as data collection tool in the research. In the analysis of the data, the Dependent and Independent Samples test was used. According to the findings obtained in the research, the experimental group, where the reading practice is carried out with the "I compete by reading" Activity, was more successful in understanding than the control group. Again, according to the research findings, it was observed that there was a significant difference between the mean scores of the experimental and control groups from the posttest of the Reading Attitude Scale. As a result, with this research, "I compete by reading" activity has been revealed to be an application that can be used in reading education.
