The influence of COVID-19 pandemic on college students' academic performance and the construction of a learning ability warning system

Objective This study explored the impact of prevention and control measures taken by Chinese universities on college students' academic performance during the COVID-19 pandemic.Participants The sample includes 1,009 senior students, 1,140 junior and sophomore students, and 1,198 freshman students studying at a top university in China from 2012 to 2023.Methods Analysis of variance was used to analyze historical data, and a learning ability warning system based on probabilistic neural networks was further proposed.Results There was a significant difference in student academic performance from 2019 to 2022 compared to historical data. Prevention and control measures such as school closures and online teaching have affected the academic performance of college students.Conclusion COVID-19 has a negative impact on college students' learning ability.
