摘　　要：《聚合物共混改性原理》课程内容涵盖知识面广,兼具理论性和实践性的特点。该课程的知识框架中,性能、组成、过程、组织形貌、相容性等诸多因素彼此关联,错综复杂,增加了学生的学习难度。本文以“聚合物共混体系的增容”为例,详细阐述了教学过程中如何构建章节知识之间的内在逻辑关系,由浅及深,层层递进,引导学生建立自己的知识体系。同时,结合相关专业课程的关联知识,构建知识桥梁,帮助学生扫清知识盲区。The course of Polymer Blending Modification Principles covers a wide range of knowledge,both theoretical and practical.In the knowledge framework of this course,many factors such as properties,composition,blending process,morphologies and compatibility are interrelated and complicated,which increases the difficulty of students learning.Herein,“the compatibilization of polymer blending system”was taken as an example to elaborate on how to construct the internal logical relationship between chapter knowledge during the teaching process,from shallow to deep,layer by layer,to guide students to build their own knowledge system.At the same time,combining the related knowledge of relevant professional courses,building the knowledge bridge,which could help students clear the knowledge blind area.
