Attending a co-taught classroom improves test scores for students with and without disabilities, especially in math. https://www.educationnext.org/are-two-teachers-better-than-one-effect-co-teaching-students/
@cara__jackson I see the very small effect sizes, and really wish for a couple of things.
1) that some of these studies would also look at measures such as student well being, belongingness etc...
2) as someone who now co-teaches at the university level, there are nuances and a developmental trajectory to co-teaching. Co-teaching in some ways is extremely difficult and requires a partnership, planning time, and time to work through teaching styles and approaches. I wonder what outcomes are for say teachers who have been co-teaching for 2+ years.
@ZingerLearns totally agree on both points - I can see how we might expect to see effects on the social-emotional well-being of students and the efficacy of co-teaching seems likely to vary. I co-taught one year but we were given very little guidance or structure to maximize the potential.
