Subclaims

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.

q4 i1 Relative to control, the intervention reduced the prevalence of fixed mindset self-reports among lower-achieving adolescents, standardized effect size 0.33. → Yeager 2019

q4 · i1 · causal · r3

Self-reported fixed mindset measured at the end of the second session in the national randomized experiment. The intervention "reduced the prevalence of fixed mindset beliefs relative to the control condition" (standardized mean difference effect size of 0.33, n = 5,650, k = 65).

"the growth mindset intervention reduced the prevalence of fixed mindset beliefs relative to the control condition, reported at the end of the second treatment session, unstandardized B = −0.38 (95% confidence interval = −0.31, −0.46), standard error of the regression coefficient (s.e.) = 0.04, n = 5,650 students, k = 65 schools, t = −10.14, P < 0.001, standardized mean difference effect size of 0.33"

Studies bearing on this claim

Can a brief intervention, a programme or a teacher change a learner's mindset? This table gathers the studies behind this claim and the 3 narrower claims that bear on it: 4 distinct studies (2 causal, 1 review, 1 associational), q2–q4, 1 of 4 with an effect size coded. One row per study, codes as each entry records them; no effect is averaged and no verdict is drawn. Built by scripts/synthesize_claim.py from eval/synthesis/; a row that looks wrong is fixed on the claim it comes from.

Discussion

Learner Variables

- Growth-mindset interventions have weak average effects on achievement, including a negligible GPA gain (d = 0.11) for lower-achieving US ninth-graders in one preregistered national trial — the general claim this finding bears on, with the studies behind it
