摘　　要：为了满足新时代多学科背景复合型人才培养需要,尤其是培养理工融合拔尖创新人才的需要,基于近年来的教学实践,以“液晶电光效应实验”为例,从教学方式、知识结构以及实验内容3个角度,对如何提高近代物理实验教学质量进行了探究。课堂教学采用互动式问题驱动;有机融入液晶科学发展及其显示工程应用,强调基础研究发现和工程应用的内在联系,培养理科学生的工程创新意识;引导学生进一步自主探究,如研究不同电场条件下液晶衍射图案现象,鼓励学生观察、记录和探究不同衍射图案的出现条件及其演化规律,进而探讨对应的液晶微结构基础,并从自由能的角度阐释相应的动力学相变行为。通过自主探究,巩固融合学生理论物理知识,训练学生探究能力,培养学生科技创新意识。In order to meet the requirement of multidisciplinary-talent,especially for science-engineering integration talents,based on the teaching practices in recent years,taking“Electro-optic Effect Experiment of Liquid Crystals”as an example,we explore the experimental course reforms from three key aspects of knowledge structure,teaching modes,and experimental contents.The classroom teaching adopts interactive problem driving.The development of liquid crystal science and its application in display engineering are organically integrated into the course.It emphasizes the internal connection between basic research discovery and engineering application to cultivate students the engineering innovation ability.It also guides students to further independent exploration,such as studying the phenomenon of liquid crystal diffraction patterns under different electric field conditions,encourages students to observe,record and explore the emergence conditions and evolution rules of different diffraction patterns.It explores the corresponding liquid crystal microstructure basis,and explains the corresponding dynamic phase transition behavior from the perspective of free energy.Through independent exploration,students’theoretical physics knowledge is consolidated and integrated,the exploration ability in enhanced,and consciousness of scientific and technological innovation are promoted.
