The aim of this study is to evaluate the effectiveness of foreign language teaching with gamification applications in primary school. In this research, embedded design, which is one of the mixed methods in which quantitative and qualitative methods are used together, has been adopted. The study group for this research is comprised of 33 students in 4th grade at a primary school. Research data were collected through an attitude scale for English lessons in primary school, homework, a follow-up chart, and a semi-structured interview. The data of the scale were subjected to inferential statistics; the data of the chart were subjected to descriptive statistic s; and the data of the interview were subjected to content analysis. According to the findings of the study, the gamification applications significantly increase the attitude of primary school students and have a positive effect on procrastination behaviors.
