As a result of the COVID-19 pandemic, many university students have transitioned from face-to-face education in the classroom to online learning. Online learning support services (OLSS) have helped university students adapt to this new form of learning. However, the quality of OLSS may influence learning experiences and satisfaction with online learning. High-quality OLSS could improve the effectiveness of online learning and improve satisfaction rates, thus better meeting students’ education requirements. Therefore, it is of great value for us to explore the effects of OLSS on university students’ learning satisfaction. This study proposed three hypotheses to evaluate the effects of three dimensions of OLSS (cognitive support, emotional support, and management support) on the learning satisfaction of university students. Data were collected through a survey and were then analyzed using confirmatory factor analysis (CFA) and structural equation modeling (SEM). We found that cognitive, emotional, and management support services each had positive correlations with the learning satisfaction of university students. Overall, our results suggest that learning support services should focus on the cognitive, emotional, and management aspects of online learning, thereby meeting personalized learning needs, improving service quality, and promoting online learning.
