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.
q1 i? The four evidence types differ in whether they can provide strong support for claims about effectiveness, which the guide explains type by type. → Gregory Chojnacki 2016

- Prompting learners to self-explain, one generative strategy, improves learning by a moderate average amount; other generative activities are not tested by the evidence recorded here — related
- Evidence types differ systematically in probative value: detection outputs cluster at weak inferential force while admissions, observed exam behaviour and fabricated references carry the strongest profiles — related
