Whole Class Inclusion: Some districts (like those in California) are placing dually certified teachers in classrooms as social studies, math or English Language Arts teachers in secondary classrooms. The teacher teaches the subject to both students with and without disabilities and carries a caseload of students enrolled in a specific grade, etc. They would most likely call these "inclusion classrooms" and include students who are English Language Learners or struggling with grades.

Push In: A resource teacher will come into the general classroom and meet with students during centers time to support their IEP goals and provide small group or individualized instruction. Often districts will encourage teachers to provide a mix of push in and pull out services. Sometimes the services are provided by a para-professional at the direction of a special education teacher.

Pull Out: This sort of "pull out" is usually indicated with a "Resource Room" placement in the IEP.  Students who have significant problems with attention and staying on task may benefit from a quieter setting without distractions. At the same time, children whose disabilities put them at a significant disadvantage with their typical peers may be more willing to "risk" reading aloud or doing math if they aren't worried about being "dissed" (dis-respected) or mocked by their general education peers.
