There are a number of teaching strategies for learners with special educational needs (SEN). But, the focus of this study is co-teaching between special education teachers and general teachers. Co-teaching is seen as a way to promote inclusive education. The overall aim of the study is to contribute to a deeper understanding how co-operation between teachers can promote learning of all pupils in a general education context. The specific aim of the study is to describe and analyze the strategies the teachers use during co-teaching. Co-teaching has been suggested as a way to offer education for all pupils in the general education classroom. Co-teaching can be defined as a form of co-operation where at least two teachers teach in the same classroom at the same time. The teachers collaborate with each other in order to teach pupils with and without disabilities in the same classroom, focusing on the use of collaborative and differentiated instructional strategies that can promote and increase the accessibility of curriculum content for all learners. Such a research programme should examine teaching and learning in real settings as it will need to take account of the ways in which teachers do their work in relation to the wide variety of situations they face.
