    Exploring the relationship between teacher and parent support and students’ noncognitive outcomes via Latent Profile Analysis by Yahan He, Tommy Tanu Wijaya, Akhmad Habibi, Huaqing chen, Mengfei Gao

    Published 2025-01-01
    “…We applied Latent Profile Analysis to analyze data from 274 secondary school students in China, identifying four distinct profiles of teacher–parent support: low teacher support–low parent support, medium teacher support–low parent support, high teacher support–low parent support, and high teacher support–high parent support. Analysis of variance was employed to analyze the differences in noncognitive support across these profiles, identifying significant differences in self-confidence, interest in learning, and anxiety across profiles; however, surprisingly, teacher and parent support were not significantly correlated with attitude or student activeness. …”
