Why some students excel in mathematics: growth mindset, intrinsic motivation, and school autonomy in top-performing Asian and Western economies

Abstract Mathematical proficiency in adolescence is crucial for both individual success and national economic development; yet few studies have examined cross-national differences in how achievement-related beliefs, motivations, and institutional factors affect mathematical outcomes. Specifically, this study filled the gap by investigating the impact of growth mindset, intrinsic motivation, and school autonomy on students’ mathematics performance across five top-performing Asian (Singapore, Macao, Hong Kong, Taipei, and Korea) and five top-performing Western (Switzerland, Ireland, Denmark, the United Kingdom, and Poland) education systems. We used the Programme for International Student Assessment 2022 dataset (N = 66,789) and multilevel mediation analyses to reveal that (a) growth mindset was positively associated with mathematics performance in all five Western economies and two Asian economies (Singapore and Taipei). (b) Intrinsic motivation mediated the pathway from growth mindset to mathematics performance in four Western economies (Ireland, Denmark, the United Kingdom, and Poland) and all five Asian economies. (c) School autonomy exhibited context-dependent moderating effects, strengthening the influence of growth mindset in Korea while amplifying the association between intrinsic motivation and mathematics performance in Singapore. This study highlights the importance of aligning educational interventions that target students’ motivational beliefs with the cultural and institutional contexts in which they are implemented.
