Exploration of Modern Physics Experimental Teaching Based on the Cultivation of Innovative Talents——Taking"Liquid Crystal Electro-optic Effect Experiment"as an Example
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.
