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? Even restricting attention to the most able schools and teachers observed, the report finds no evidence that 300 minutes of instruction fits within a 330-minute day, and suggests a 360-400 minute day is needed. → BetsAnn Smith 1998

q2 · i? · associational · r2
From the report's synthesis of its day-level observation data, even the best-managed classrooms could not deliver the allocated 300 minutes; the authors conclude a 300-minute instructional program "must be nested within a school day that is between 360 and 400 minutes long."
"Even when we restrict our view to the most able schools and teachers observed, we have no evidence that 300 minutes of instruction can be delivered within a 330-minute school day. Teachers cannot cover schoolwide operational demands in 30 minutes, and they cannot deliver effective instruction without intermittent segments of class preparation and management."
