Schools are required by the Individuals with Disabilities Education Act of 2004 (IDEA) to include students with disabilities in the general education classroom. Recently there has been emphasis on co-teaching as a method to comply with this mandate. Co-teaching is a technique geared at utilizing a special education teacher and a content area teacher to concurrently instruct both students with and without disabilities in the general education setting. It is well established in the literature that it is vital that together both the content area teacher and special education teacher in these settings be effectively trained to meet the needs of the students with disabilities without hindering the progress of the students without disabilities (Fleming & Bauer, 2007; Goor, 1994; Dieker, & Murawski, 2003). This study investigated the perceptions of special education and content area teachers with and without experience co-teaching of co-teaching. Twenty-two content area and fifteen special education teachers with and without co-teaching experience and currently enrolled (academic year of 2012-2013) in the graduate course of ED530 Teacher as a Researcher at Bridgewater State University responded to an 82-item survey to identify their experience and perspectives on co-teaching. Results of this study identified several features of content area and special education teachers' experience and views of co-teaching. Recommendations are offered for future research in the area of co-teaching and co-teaching professional development.
