Defining the concept of inclusion Defining the concept of inclusion is a challenging task (Armstrong et al., 2011; Moberg & Savolainen, 2003). As Armstrong et al. (2011, p. 31) have stated, "It is not simply that inclusion means different things to different people but rather that inclusion may end up meaning everything and nothing at the same time." The various definitions of inclusion can be divided between narrow and broad (Ainscow et al., 2006). Narrow definitions promote the inclusion of specific groups of students, such as disabled students. Broad definitions, on the other hand, focus on diversity and how schools respond to the diversity of all students (Armstrong et al., 2011, p. 31). In the context of education, inclusion has often been connected exclusively with disability and special education (Arnesen, Mietola, & Lahelma, 2007; Miles & Singal, 2010), which yields a narrow definition. Thus, in the minds of many people, inclusion refers solely to a particular group of children, namely, students with special learning needs (Smith, 2006). However, as the following example from the UNESCO Salamanca Statement shows, inclusion reaches further: The guiding principle that informs this framework is that schools should accommodate all children regardless of their physical, intellectual, social, linguistic or other conditions. This should include disabled and gifted children, street and working children, children from remote or nomadic populations, children from linguistic, ethnic, or cultural minorities and children from other disadvantage or marginalized areas and groups.
