Lesson Planning for Inclusion and Co-Teaching: Making It Work for Every Student

Inclusion — placing students with disabilities in general education settings with appropriate support — is both a legal mandate and an educational philosophy. The research on well-implemented inclusion is positive: students with disabilities make greater academic and social gains in inclusive settings than in segregated special education classrooms, and general education students are not harmed by the presence of peers with disabilities. The emphasis on "well-implemented" matters, because poorly implemented inclusion produces few of these benefits and sometimes harms the students it's meant to serve.

Co-teaching — the primary model for delivering inclusion services — pairs a general education teacher and a special education teacher in the same classroom. When it works, students receive content expertise and specialized support simultaneously. When it doesn't, one teacher is effectively an aide while the other teaches, and students with disabilities are marginalized within the general education setting.

The Six Co-Teaching Models

Marilyn Friend's co-teaching framework identifies six approaches, each useful in different instructional contexts:

One teach, one observe: One teacher leads instruction while the other collects data on specific students or the whole class. Useful for assessment, but not sustainable as the primary model.

One teach, one assist: One teacher leads instruction while the other circulates to support. This is the most common co-teaching arrangement and the one most likely to devolve into aide-teacher dynamics. Works well for transitional activities; works poorly as the primary instructional model because it underutilizes the second teacher.

Station teaching: Both teachers run different stations while students rotate. Allows differentiated instruction and smaller groups simultaneously.

Parallel teaching: Both teachers teach the same content to half the class simultaneously. Reduces class size without tracking; allows more active participation.

Alternative teaching: One teacher works with a small group on different content (pre-teaching, re-teaching, enrichment) while the other teaches the class. Allows targeted instruction without pulling students.

Team teaching: Both teachers instruct together simultaneously, building on each other's expertise. The most demanding to implement but produces the most integrated co-teaching relationship.

Effective co-teaching programs use multiple models throughout a week rather than defaulting to one teach/one assist for everything.

Planning Together: The Non-Negotiable

Co-teaching without co-planning produces one teacher's lesson with the other teacher present. Genuine co-teaching requires time to plan together — both teachers contributing their expertise to the lesson design.

What effective co-planning looks like: the general education teacher brings content knowledge and curriculum pacing; the special education teacher brings knowledge of individual student needs and specialized instructional strategies. The resulting lesson plan should show the fingerprints of both: the content is rigorous, the supports are built into the lesson design rather than added as afterthoughts, and both teachers have clearly defined roles throughout.

Non-negotiable planning elements for inclusion:

Universally designed lesson components: Materials available in multiple formats (print, audio, visual), multiple ways to demonstrate understanding, multiple ways to engage. Universal Design for Learning doesn't require a separate modified lesson for students with disabilities — it requires designing the original lesson to accommodate the range of learners in the room.

Explicit IEP accommodation implementation: Each student with an IEP has specific accommodations — extended time, preferential seating, reduced assignments, modified grading criteria. These need to appear in the lesson plan, not just the IEP document. Which teacher is responsible for which accommodation during which part of the lesson?

Specific data collection targets: What are we measuring, for which students, using what method? The observation data from one teach/one observe is only valuable if it connects to specific IEP goals and informs instruction.

Differentiating Without Stigmatizing

A persistent inclusion challenge is providing appropriate support without marking students with disabilities as different in ways that damage their social belonging. Students who receive obviously different materials, who are always pulled into small groups while peers work independently, or who have a teacher obviously hovering over them are receiving disability-specific support at the cost of social inclusion.

Universal designs that benefit all students without singling anyone out: graphic organizers available for everyone, sentence frames posted for the class, choice in response format, flexible seating. When the scaffold is available to everyone, using it carries no stigma.

When individualized support is genuinely necessary: delivery matters. A student who receives extended time has less of a visibility problem if everyone has the option of working during a dedicated extended work period. A student who needs reduced text encounters less stigma if they're using an alternative format (audio, large print) rather than visibly receiving a shorter version of the same assignment.

What Makes Inclusion Fail

One teacher is primary, the other is secondary. Students quickly perceive the hierarchy and treat the special education teacher as a paraprofessional rather than a teacher. Students with disabilities associate with the secondary teacher rather than the class, which defeats the purpose of inclusion.

Students with disabilities are only present, not participating. A student who sits in the back with a modified assignment while the class does different work is physically included and educationally excluded. Inclusion requires instructional design that makes the same learning targets accessible to everyone.

No shared planning time. Co-teaching without planning together is not co-teaching — it's parallel occupation of a room.

IEP goals aren't integrated into daily instruction. If a student's IEP goals are only addressed in pull-out sessions rather than embedded in the inclusive classroom, inclusion isn't achieving its purpose.

The Special Education Teacher's Role

Special education teachers in co-taught settings sometimes feel their expertise is underutilized — they're managing behavior, distributing papers, and supporting individual students rather than teaching. This is both a waste of expertise and a model that doesn't serve students well.

Special education teachers have specific expertise: diagnostic assessment, instructional strategies for learning differences, behavioral support, assistive technology, and knowledge of individual students' strengths and needs. Good co-teaching structures treat this expertise as a teaching resource, not a support resource. Parallel teaching, team teaching, and alternative teaching all give the special education teacher genuine instructional roles that serve all students.
