In the context of the new liberal arts,enhancing and stimulating the development of higher-order thinking in learners has become a focal point in higher education.Current issues in Master of Public Administration(MPA)classrooms include an emphasis on knowledge transmission over the cultivation of thinking skills,passive and silent classroom interactions,and a lack of diverse assessment methods to measure competencies.To address these issues,this paper uses the core course"Public Administration"for MPA students as a case study,implementing reforms and dynamic adjustments in teaching content,models,and feedback mechanisms.A new multimodal whole-process teaching model has been developed,aimed at fostering students'higher-order thinking and core competencies.The research results indicate that this new teaching model is effective and has significant potential for broader application,providing important references for classroom teaching reform in public administration programs.
