成长型思维对大学生教育获得感的影响:坚毅和学习投入的链式中介作用

Effect of growth mindset on sense of educational acquisition in undergraduates:The chain mediating effect of grit and academic engagement

目的:考察坚毅和学习投入在成长型思维与大学生教育获得感之间的中介作用机制。方法:采用成长型思维模式量表(GMS)、坚毅量表(GS)、学习投入量表(AES)和大学生教育获得感量表(SEAS)对762名在校大学生进行问卷调查。结果:积差相关分析结果表明,大学生的成长型思维、坚毅、学习投入和教育获得感两两之间存在显著正相关(r=0.173~0.610,P<0.01)。路径分析结果表明,成长型思维对大学生教育获得感的直接预测作用不显著。中介效应分析结果表明,坚毅和学习投入在成长型思维与大学生教育获得感之间分别起完全中介作用,各占总间接效应(0.185)的百分比为19.4%(0.036)和44.7%(0.083)。坚毅和学习投入在成长型思维与大学生教育获得感之间的链式中介效应显著,占总间接效应(0.185)的百分比为35.9%(0.066)。3条路径的中介效应大小差异不显著。结论:坚毅和学习投入在成长型思维与大学生教育获得感之间既存在单独中介效应,又存在通过坚毅影响学习投入的链式中介效应。

Objective:To investigate the mediating mechanism of grit and academic engagement between growth mindset and sense of educational acquisition in college students.Methods:A sample of 762 undergraduates was recruited to complete Growth Mindset Scale,Grit Scale,Academic Engagement Scale and Undergraduates’Sense of Educational Acquisition Scale.Results:Correlation analysis showed that there were significant positive correlations between college students'growth mindset,grit,academic engagement and sense of educational acquisition(r=0.173~0.610,P<0.01).The result of path analysis showed that the direct prediction effect of growth mindset on college students'sense of educational acquisition was not significant.Mediating effect analysis showed that grit and academic engagement played completely mediating role between growth mindset and college students'sense of educational acquisition respectively,with the percentage of total indirect effects(0.185)being 19.4%(0.036)and 44.7%(0.083).The chain mediating effect of grit and academic engagement between growth mindset and sense of educational acquisition of college students was significant,accounting for 35.9%(0.066)of the total indirect effect(0.185).The effect sizes of the three mediating pathways were not different significantly.Conclusion:Grit and academic engagement have both separate and chain mediating effect(from grit to academic engagement)between growth mindset and college students'sense of educational acquisition.
