Students in classrooms of team teachers led by “multi-classroom leaders” showed sizeable academic gains, according to a new study from the American Institutes for Research and the Brookings Institution.
The team teachers were, on average, at the 50th percentile in the student learning gains they produced before joining a team led by a multi-classroom leader. After joining the teams, they produced learning gains equivalent to those of teachers in the top quartile in math and nearly that in reading, said the report, released on January 11, 2018, through the CALDER Center.
The gains the study attributes to team teachers are equivalent to those of teachers from the 75th to 85th percentile in math, and, in six of the seven statistical models, from 66th to 72nd percentile in reading.
These results show that students can consistently experience top-quartile teaching in math, and teaching nearly that good in reading, if schools place excellent teachers in charge of small teams of typical teachers.
