The purpose of this study is to investigate how two elementary schools work with Swedish and Swedish as a second language through four teachers thoughts and perceptions. My issues are: How do the teachers perceive the Swedish classes in the school, and how do they perceive that they are conducting it? Which examples of material for teaching do the teachers show me and how do they use it in each school? Do the work with Swedish and Swedish as a second language in the multi-ethnic school and the more mono-ethnic school differ according to how the teachers perceive they are conducting it? Do the teachers think that the equivalent education that is part of the curriculums values and mission always is maintained and why/why not? My study is performed from a sociocultural perspective. My conclusions are that the teachers from the multi-ethnic school are more aware of how to work with Swedish or Swedish as a second language regardless of the students ethnic or national origins. Some aspects of how the teachers work with Swedish are equal with each others, but there are differences to. The teachers do not think that the education always is equivalent.
