A growth mindset is not a promise that effort alone guarantees improvement. It is the view that abilities can develop through learning and experience. In Yeager et al.’s national experiment with U.S. secondary students, a less-than-one-hour online intervention improved grades among lower-achieving students and increased advanced-math enrollment overall. The peer-norm finding concerns grade effects among lower-achieving students in schools where norms supported challenge-seeking; it does not describe the advanced-math enrollment result. The experiment does not guarantee the same result in every school or for every learner. Yeager et al., original study

Turn the message into a learning action

  • Instead of “try harder,” ask where the learner got stuck and which strategy they tried.
  • Choose one next strategy, practice briefly, and check what changed. Treat asking a teacher or peer for help as a learning action too.
  • Look beyond a single score: note whether the learner uses the strategy, asks for help, and revises an error on a similar task. Interpret results alongside prior performance and classroom norms.

Example: If a student misses a fraction problem, avoid labeling them as “not a math person” or promising that effort alone will fix it. Review the step where denominators were combined, try a visual model or another worked example, then check whether the approach works on a new problem.

Sisk et al. conducted separate meta-analyses of the association with achievement (273 effects; N=365,915) and intervention effects (43 effects; N=57,155); overall effects were weak in both. Some students at academic risk or with lower socioeconomic status might benefit, but the findings do not promise achievement gains for all learners. One encouraging phrase or lesson cannot be assumed to raise grades by itself. Sisk et al., “To What Extent and Under Which Circumstances Are Growth Mind-Sets Important to Academic Achievement? Two Meta-Analyses” (2018)
