Reading the evidence codes

q is the design tier, i the impact, n the sample, and the kind with its r the rigour judged within that kind: what each code means.

This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.

q2 i? Half of top-quartile teachers describe strong joint problem solving and an additional 13 percent describe very strong processes, whereas bottom-quartile teachers are most likely to describe their joint problem solving as weak (46 percent). → Anthony Bryk 1997

q2 · i? · associational · r1

Descriptive quartile comparison from the Joint Problem Solving scale summary, which examines how well teachers talk through and solve problems with one another, including use of faculty meetings for problem solving. No significance test is reported.

"Half of the teachers in the top quartile schools describe strong joint problem solving processes, while an additional 13 percent describe very strong processes. Teachers in the bottom quartile schools, on the other hand, are most likely to describe their joint problem solving as weak (46 percent)."
