The aim of this study is to understand how mobile devices are being used to support students' learning (i.e., mobile learning) in specialist schools, and in specialist support units within mainstream schools. A validated survey instrument is used to examine these practices through the lens of a sociocultural digital framework that highlights distinctive mobile learning approaches. One hundred and twenty-six teachers responded to the survey. The findings provide a nuanced understanding of teachers' current digital pedagogical approaches, and show potential benefits for students, including increased agency. Possible directions for the development of special education teachers' digital practices are also provided.
