"Personal Information Form", "Attitudes Towards Learning" and "Computer Addiction for Adolescents" scales were used in order to collect research data. By analyzing the data with t test, one-way variance analysis (ANOVA) and correlation statistical research techniques in the SPSS 22.0 program, findings were obtained. A significance level of 0.05 was taken as the basis in the applied statistics. As per the findings, a difference was found in terms of internet addiction according to gender, academic achievement, homework habits, family activity frequency variables. Furthermore, a negative relationship was found according to the correlation analysis result between students' attitudes towards learning and internet addiction.
