Under the background of “ New Infrastructure” and new generation of information technology , theteam of the Physies E'xperiment Center of Harbin Institute of Technology ( Shenzhen )organically combinesphysics experiment teaching with information and communication technology , and develops a series of physicalexperiment projects related to fiber-optic communication technology. Taking the magneto-optical effect as anexample , an online virtual simulation experiment projeet was developed. The organic integration of online andoffline teaching methods makes the teaching method more flexible.The course content is scientific , intuitive and interesting, and can realize hierarchical teaching, which greatly stimulates students’interest in learning andinnovative practical ability , enabling them to achieve excellent results in competitions and greatly improving the quality of teaching.
