Believing practice predicts grades

A study of 249 Norwegian secondary students found that students who endorse a growth mindset (believing effort and practice improve ability) and who report high self‑efficacy get better grades and enjoy subjects more than peers who rely mainly on passion or grit. The effect showed up across both academic (language) and nonacademic (physical education) classes, suggesting the attitude is broadly influential. — If replicated, the result implies education policy and school interventions should prioritise cultivating belief in improvability and self‑efficacy over exhortations to 'grit' or talent myths.
