The purpose of this study is to present an example social studies activity supported by QR code application and to determine the opinions of teachers and students on this experience. The study was conducted with the participation of 41 students and 2 teachers from two 4th grade classes in a primary school in Giresun, Turkey. The research was designed as a case study and the implementation lasted 2 weeks. In the study, semi-structured student interview form and unstructured teacher interview form developed by the researchers were used as data collection tools. Findings were obtained by analyzing the data using content analysis. The results revealed that social studies teaching supported by QR code application contributed to improvement of cognitive and affective behaviors of the learners. It was also found that the students did not often use QR code applications in the learning activities except for their use on the smartboard.
