| With the development and progress of science and technology,more and more electronic products are integrated into our daily lives,and the society’s demand for various electrical and electronic professionals is also increasing.In order to keep pace with the times and cultivate professional and technical talents that meet the needs of society,secondary vocational schools have become the main base for training national front-line technical talents."Electrical Basics",as an important public basic course for the majors of electrical and electronics in secondary vocational schools,plays an important role in training students’ basic theoretical and practical skills.In particular,the experimental teaching interspersed among them,through the implementation of effective experimental teaching,can not only verify the theory,but also enhance students’ practical and innovative ability.However,there are still many problems in the experimental teaching,which restricts the effective improvement of students’ practical ability and innovation ability.NI ELVIS Ⅱ is a powerful circuit experiment platform which provides a variety of virtual instruments.Based on the platform supplemented by appropriate experimental teaching design,it is possible to carry out effective experimental teaching combining reality and reality.On the one hand,students can not only verify their knowledge through virtual experiments,but also design related circuits for actual measurement;on the other hand,in the process of combining virtual experiments and physical experiments,students can expand their knowledge,To bridge the gap between theory and practice measurement,to achieve the purpose of training students’ comprehensive practical ability and innovative ability.Based on the research on the status of the application of virtual instruments at home and abroad,this subject is based on a variety of educational and teaching theories,such as the learning pyramid theory and multiple intelligence theory.The secondary vocational and technical schools carry out the theory and methods of electrical and electronic virtual-real combination experiment teaching,and carry out experiment teaching design for "Kirhoff’s law" and "Capacitor charge-discharge" torealize the experimental teaching of virtual-real combination.Studies have shown that by effectively carrying out virtual-real combination experiment,students can not only strengthen their practical skills,mobilize their enthusiasm for learning,but also mobilize their enthusiasm for learning and stimulate their creativity. |
