Instruction in Co-Teaching in the Age of Endrew F.

The authors built a co-teaching model for general-ed classrooms.

They tracked one team for an unstated length of time.

Teacher and student behaviors were measured, but the paper does not say how many or for how long.

Both teachers and students changed their behavior.

The paper does not tell us if the changes were big or small, good or bad.

Beamish et al. (2021) also tested a classroom package. Their teachers felt more confident, yet their actual teaching did not budge. de Korte et al. (2021) saw change, but we do not know if practice moved too—so the two studies may not clash; they just measure different things.

Yi et al. (2021) and Morrison et al. (2017) warn that training plans can flop when staff stick to scripts and skip warmth. de Korte et al. (2021) stay silent on fidelity, so their model might dodge the script trap—or might repeat it. We cannot tell.

Ming et al. (2017) note that ABA lessons rarely teach “difference” relations. A co-teaching pair could fold oddity trials into shared lessons, but the model has not done so yet.

You now know a co-teaching blueprint exists and can move classroom behavior. Ask your school team to list which teacher does which ABA step before the lesson starts. Track one kid and one teacher goal for two weeks. You will quickly see if the plan works or needs a tweak—no fancy data kit required.
