Design And Implementation Of Computer Aided Instruction System In Secondary Vocational School Based On VARK Model

It is an inevitable trend of development to develop and integrate courses by applying information technology to modern education and teaching.With the "Internet plus" era,It is a subject worth exploring to develop a CAI after classroom and use multimedia teaching,online testing and evaluation of information to enhance students' learning ability.It is also the motive force of distance teaching and education in secondary vocational schools.In order to conform to the trend,this paper studies the design and implementation of CAI in secondary vocational school based on VARK model.Design and completion of the main tasks include:(1)Survey the application and research of CAI;Introduce and analyze CAI at home and abroad;Describe the basic theory involved on the system deign and realization and the related technology.(2)Analyze the need of CAI;Expound the design objectives,principles,Functional requirements of CAI;Build the overall architecture of the computer assisted instruction system;Design the corresponding functional modules on the basis of the system.(3)Analyze the database design of CAI;Analyze the implementation of the BP neural network in the student evaluation module,the design of the online test module,the extraction and display of the test questions module.(4)Test the function of CAI;Test the response time and the concurrent ability of the system.This thesis presents the design and implementation of VARK model based on the "secondary vocational school CAI system",It realizes the communication between teachers and students,students' learning,online exercise and examination of the network,Both of them can share the resources.The system can help to cultivate students' interest in learning,reduce teachers' pressure for preparing and reviewing exercises and test pressure.And it can also enhance the information level of teachers and students.
