The purpose of this study is to examine the use and application of the curriculum cycle in Swedish as a second language teaching and how the relationship between theory and practice might look like. The questions that formed the basis of this study addresses how the curriculum cycle is used in teaching of Swedish as a second language and how the curriculum cycle is applied in teaching materials for students learning Swedish as a second language. The research methods chosen for this study are a qualitative semi-structured interview study and a qualitative teaching material analysis where I interviewed three teachers and analyzed two textbooks. The theory on which this study is based is Vygotsky's sociocultural theory of learning that clarifies the idea of that communication and interaction between people are crucial parts for how sociocultural resources are formed and passed on. After analyzing the interviews, it can be concluded that it is used frequently where each phase is essential in order to achieve the goal. The teachers also explained that the students develop cooperation and communication skills and a learning experience where they learn from each other when accomplishing the phases. The other method used in this study was a systematic conceptual analysis focusing on verbs in imperatives where I studied which forms of work and phases of the curriculum cycle that were presented in textbooks for Swedish as a second language. As a result, it can be concluded that the curriculum cycle is applied as a method and a tool with different strategies that help students to achieve a certain goal. The analyses also showed that both teaching materials contain elements where students work individually, in pairs and in groups.
