#academictwitter It& #39;s time to update how we teach about effect sizes & the policy relevance of research findings.

Here are some resources:

1) I& #39;m hopeful my paper can serve as an accessible introduction to interpreting the importance of effect sizes.

3) A picture is worth 1,000 words. We need to help students to create better visualizations of research evidence.

Or even simple visual guides like this from @Stata

4) We need to teach students about opportunity costs and unintended consequences to contextualize policies and programs.

This @J_HumanResource paper by Jepsen & Rivkin on reducing class sizes in CA is one of my favorite examples:

6) Let& #39;s encourage students to ask - can that program or policy be effective at scale?

This @IESResearch i3 report about attempts to scale promising education interventions is sobering

7) We also have to reaffirm for students the value of the "gut-check."

Does an effect seem plausible & make common sense?

Is there a theory of action & causal chain of events that would explain the findings?

Check out @NoraEGordon & @clconaway new book for a practical guide:
. . . and here is a paper that provides empirical ES benchmarks for metal health and prevention programs.
