This paper reports on the findings of an international comparative research project where the roles of teachers in the implementation of inclusive education in mainstream-classroom settings in South Africa and Finland were investigated. Inclusive education within this project is broadly defined as welcoming all students to general-education schools and classrooms and not segregating students on the basis of ability or other individual or sociocultural characteristics. In this paper a qualitative analysis of Finnish and South African teachers' day-to-day teaching and learning support practices in their classroom is discussed. Individual and focus-group interviews encouraged teachers to articulate their views in this regard. Initial findings indicate that despite the dissimilar cultural and historical contexts of these two countries, both complex contextual issues and classroom practices based on a medical-deficit understanding of diverse educational needs play a role in Finnish and South African classrooms.
