| Abstract: | Co‐teaching is a popular strategy for implementing the inclusion of students with disabilities within secondary general education classrooms. However, we have little data regarding its effectiveness under routine conditions of educational practice. This study examined whether there was an “additive effect” of the special education teacher on the instructional experiences of students with disabilities as compared with the experiences of the same students taught by only the general education teacher under routine conditions. Observers used time sampling methods to document how students with disabilities spent their time in 11 middle school co‐taught classes. Statistically significant differences were found for targeted students in terms of general education teacher interaction and individual instruction. General education teachers spent significantly less time with students with disabilities when the special education teacher was present. In addition, students with disabilities received significantly more individual instruction when the special education teacher was present. However, these differences were of limited practical significance. |
