The developments in technology bring to mind the questions of how the acquisitions and contents of the curriculum in the foreign language teaching process can be transferred to the students in a more effective and permanent way and which methods and technological opportunities can be used in the education process, revealing that different perspectives and different methods should be used. In this context, the aim of this study is to create an exemplary digital instructional design to be used in teaching German as a second foreign language with augmented reality technology at the secondary school level and to evaluate the effectiveness of this design through a pre-test, a post-test, and in line with the opinions of the students participating in the application. In order to achieve this aim, one group pre-test-post-test design, which is one of the experimental designs, was preferred. A dependent groups t-test was used in the analysis of the data obtained in the single-group pre-test post-test design. The research group for the study consists of 20 9th grade students at Turgut Reis Anatolian High School in Mugla. In the study, semi-structured interview questions were prepared in order to determine the opinions of the students participating in the application on the use of technology in German lessons at the secondary education level. Descriptive analysis was used to analyse the data obtained by the interview technique. As a result of the study, it was seen that there was a significant difference between the pre-test and post-test scores of the students. It has been concluded that the students in the course where digital content is used through VR glasses show more progress and are more successful.
