基于递阶式O-AMAS的环境微生物学混合式教学模式探索OACHSSCD

With the continuous advancement of first-class curriculum construction in universities,online-offline blended teaching,which integrates the strengths of traditional classroom teaching and online teaching,has gradually become the mainstream curriculum implementation mode in institutions of higher education.This paper takes the Environmental Microbiology course as an example and implement the online-offline blended teaching reform and practice to tackle such issues as obvious gaps in students'biological foundations,lack of awareness in independent learning and collaboration,and low levels of curriculum participation.Adhering to the teacher-led and student-centered principle,the curriculum team constructed a hierarchical O-AMAS online-offline blended teaching mode for Environmental Microbiology through optimizing curriculum teaching system,constructing curriculum resource,designing and implementing learning tasks,and reforming curriculum assessment methods.Through the use of the Chaoxing FanYa online teaching platform,hierarchical design is conducted for task assignment,knowledge expansion,and learning evaluation.Multiple teaching approaches including students'online self-learning,chapter quizzes,offline group cooperation and communication,intelligent evaluation and course summary are integrated into course teaching.After four rounds of teaching practice,it is demonstrated that the hierarchical O-AMAS blended teaching mode can effectively stimulate students'learning enthusiasm,The mode exerts positive effects on improving students'collaborative communication and continuous learning ability,and promoting students'in-depth participation throughout the entire teaching process.
