<p>In this study, the views of special education teachers and pre-service teachers on the TÜBİTAK 4008 Beyond Barriers with STEM Project, which includes the implementation of STEM activities in special education, were examined; the expectations of both groups from the project, whether these expectations were met, and the adaptation of STEM activities implemented within the scope of the project in special education were evaluated. A case study, one of the qualitative research methods, was adopted, and typical case sampling, one of the purposeful sampling methods, was used. The study involved 24 special education teachers and 24 pre-service teachers. First, pre-service teachers and then teachers in the study group were informed about STEM, and 16 activities lasting 4 days were carried out with each group. Then, the opinions of the teachers and pre-service teachers about the project and the adaptations of the activities in the project were examined using the “Opinion Form on Expectations for the Project” and “Opinion Form on Adaptation of Activities” prepared by the researchers. Data were analyzed using content analysis. The findings indicate that both groups had positive expectations, most of which were met. Participants provided concrete examples of how STEM activities, particularly the Bell Game Design and Fun Physics with Algodoo, were adapted for use in special education. The findings were discussed within the framework of the importance of STEM education in special education practices and existing research and practices.</p>
