基于“问题链”模式的量子力学教学改革与实践

Teaching reform and practice of quantum mechanics based on problem chain model

量子力学因其内容抽象、深奥而难以被学生所接受,学生上课往往被动地听教师讲解,较少进行主动思考,对于课程内容听不懂,进而不想听.基于“问题链”的教学模式,以学习成果为主导,学生为主体,通过一连串由浅入深、层层递进的问题引发学生思考,提高学生学习兴趣,对于量子力学这门课十分适用.以“态的表象”为例,探索了应用“问题链”设计量子力学课程的具体途径,提高了学生的学习积极性和独立思考的能力.

Quantum mechanics is hard to be understood by some students because of its abstract and profound content.Students often listen to teachers passively in class,think less actively.They don′ understand the content of the course and suffer a lot in class.The teaching mode based on problem chain is dominated by learning results,and students are the main body of learning.Put forward a series of consistent academic questions,which arouse students′ thinking and active participation.This teaching method is very suitable for the course of quantum mechanics.Taking the representation of state as an example,explores the specific way to design the course of quantum mechanics by using problem chain,which improves students′ enthusiasm for learning and exercises their ability of independent thinking.
