What is the new Robustness measure introduced in the Sequel?

Answer: The Robustness Index is a weighted average of five major indicators of stability: The number of meta-analyses, the number of studies, the estimated number of students, the number of effects within an influence, and the fail-safe number of studies. Each of these five measures was divided into quintiles, and the average quintile is the Robustness index for an influence (e.g., in the discussion of the thermometer above, The average across the quintiles of the five measures for Reciprocal teaching is R=5, indicating it had high robustness as the sampling was most extensive). For each influence, a Robustness index is provided, and there can be more confidence in these Robustness indices from 3-5, and those influences with Robustness indices of 1 and 2 may likely wobble as more studies are added to this influence over time.

These are more growth INSTEAD of progress to achievement and this may take more thinking and too much Growth mindset and the misleading formative assessment (when it should be formative evaluation).
