The Design Of Portable Experimental Teaching And Evaluation System

Due to the progress of network technology,the teaching form in the field of education becomes various.Multimedia teaching has gained popularity.Excellent courses and teaching resources spread rapidly and widely,which makes resources get maximum optimization.Thus in such circumstances,vocational education has also got rapidly development and has been pay more attention by many researchers.In order to adapt the need of society development,the purpose of vocational education is to cultivate possess innovative and skilled talents.The practice course of professional education occupies one-two thirds of the total curriculum.So the efficiency and quality of experimental teaching becomes more important.But in most vocational colleges there are some problems such as practice teaching resource is unreasonable,students do not understand the experiment principle and how to deal with emergent phenomenon.Most students just follow the experimental steps automatically according to experimental instruction book.In addition,if the experiment is done in traditional way,the waste of experimental material is quite serious and equipment is easily damaged.These problems have seriously hindered the development of practical teaching.The laboratory login system designed in this paper is based on the LabVIEW and Multisim.Using the unique graphical programming language of LabVIEW to design top layer,complete the user login,save user information.At the same time,using Multisim simulate circuits and finally combined the advantages of the two software,transmit the simulation results back to the login system for saving.The system can enable the teachers to manage the students intelligently.Students can sign in directly through the login time,after the simulation experiment is completed,the experiment report is submitted online on the system,and students should save the experimental report to the designated position.According to the experimental report and the experimental operation,the teacher evaluated the students' achievements.And then summed up the results to a form count the students' achievements.This system is designed with modular design which has strong portability.So it can be widely used in training institutions and education industry.Finally,according to the characteristics of electronic specialty in secondary vocational education schools,this paper describes the use of this system through an experimental course.It provides reference for users of the system.
