摘　　要：针对我校高分子基础实验教学中遇到缺乏对学生预习情况的有效评价和考核、课堂上的安全教育受限、一些实验项目在本科专业进行规模化实验教学开展困难等问题,我们探索以线上线下和"虚-实"组合教学法改革高分子基础实验的教学方式。通过优化线上教学资源和模式,建立线上预习考核机制,实现对学生学习的有效考查和科学评价。通过线上辅助线下,虚拟补充实体,增加自主设计实验,强化线上安全教育,使高分子基础实验教学突破了原有限制,提高了课程的专业性、连接性和趣味性及学生综合实验能力。In view of the problems encountered in polymer basic experiment teaching in our university,including the lack of effective evaluation and assessment of the preview situation,the limitation of safety education in the classroom,and the difficulty in carrying out large-scale experimental teaching for some experimental projects in undergraduate majors,we are exploring a teaching mode of combining online-offline and"virtual-real"teaching to reform the polymer basic experiment course.By optimizing online teaching resources,and establishing a system of online preparatory assessment,the effective examination and scientific evaluation of learning is realized.Moreover,by using online-offline auxiliary,virtual-entity complementation,increasing self-designed experiments,and strengthening online safety education,this new teaching paradigm can not only break the original limitations but also improve the professionalism,connectivity,and interest of courses,as well as comprehensive experimental abilities for students.
