We are still comparing with the teaching in heterogeneous classes.
We are still comparing with classes where the best students are not given essentially more material than the worst.
The weaker members of the teams will learn more; they have another teacher. Notice that the effect was less than that achieved by class size reduction.
As for skill grouping, this is NOT the same as ability grouping, and the teachers have to be prepared to teach differently to the various groups.
The major effect would not be on the proportion of a fixed set of questions answered correctly, but on how much is learned to a fair degree, and especially how much is understood. Few teachers at any level seem aware of the difference between regurgitation and understanding; I wonder how many multiple choice tests were used in the study. They can sometimes be somewhat reasonable, but only if nobody knows they will be used.
