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? Expert differentiation activities are organized in four phases—preparing the lesson period, preparing individual lessons, teaching during lessons, and post-lesson evaluation—with constituent skills that are highly interrelated across phases. → Frerejean 2021

Frerejean 2021

Frerejean, J., van Geel, M., Keuning, T., Dolmans, D., van Merriënboer, J. J. G., & Visscher, A. J. (2021). Ten steps to 4C/ID: training differentiation skills in a professional development program for teachers. Instructional Science. https://doi.org/10.1007/s11251-021-09540-x

q1 · i? · design · r2

Cognitive task analysis of nine expert teachers produced a skill hierarchy (Fig. 1) organized by these four phases. The authors stress that because constituent skills depend on outcomes of skills in other phases, practicing constituents in isolation makes little sense.

"Experts showed DI activities in four phases: during preparation of the lesson period, during individual lesson preparations, during individual lessons, and in post-lesson evaluations. This four-phase organization formed the core of the PD program."
