Mechanism of the Influence of University Support Internal Quality Assurance on Undergraduates’ Learning Outcome

The aim of this study is to explore the impact of internal quality assurance (IQA) activities on undergraduate learning outcomes through student engagement, both academically and socially. It focuses primarily on the support students receive from universities in academic, financial, and social aspects. The findings of this research can be applied and further developed to enhance student engagement and academic performance. The study employs structural equation modeling (SEM) with Partial Least Squares (PLS) version 4 to analyze the relationship between these factors and student engagement and learning outcomes. Various statistical tests are conducted to assess the significance of the relationships, including discriminant validity test, heterotrait monotrait ratio (HTMT), collinearity analysis, model fit, path analysis verification, and R2 values. The results indicate strong correlations and significant levels between variables, suggesting the validity of the hypotheses. Furthermore, the intermediary effect analysis shows a substantial relationship between variables. Overall, the findings suggest that IQA activities significantly contribute to improving undergraduate learning outcomes through enhanced student engagement.
