The Design And Implementation Teaching System Of Computer-aided Based VARK Model

In twentieth Century 50 times metaphase of computer assisted instruction(CAI)is proposed for the first time in USA.Later,with the development of computer information technology,development of computer assisted instruction is make a spurt of progress,status of computer assisted instruction in teaching is becoming more and more important,the computer aided teaching system based on network is reflected in its superiority,especially in Colleges and universities in the computer aided teaching is also play a decisive role.Therefore,our school will develop a set of "computer basis" course of the computer network assistance teaching system.This paper firstly studies the current situation of computer aided teaching system based on network,the deficiency of present in these systems are also found in certain of its advantages at the same time,mainly reflected no soul in the computer aided teaching system,the lack of connotation of education theory,is just a technology stack.Secondly,most of the single function,the user use difficlutly,it is difficult to get the favour of the user.There is unable to mobilize the enthusiasm of the students,students in a passive position in the interaction with the system in the process of.Aiming at the main problems of the current system at present,this paper studies the main popular modern educational theory,through comparative analysis of the full,chose Neal.Fleming VARK model as the system of educational theory.Aiming at the existing problems of the analysis of system function,system user more detailed requirements,visited a number of experienced "computer based" teacher,listen to their expectations of the system function;surveyed more than students in learning "computer foundation" the difficult.According to these valuable first-hand material,has carried on the detailed demand analysis,based on the design of the system function.On the completion of the system function design,according to the resource classification learning problems in system,mainly is the corresponding VARK model type of problem learning how resources accurately,this paper proposes the use of BP neural network to carry on the accurate classification of the resources.So the resources classification after several training accuracy is greatly improved.This paper also introduces the main modules of the system page,has made the detailed elaboration to these pages function,also introduced the system test part of the realization of the main class code.Finally,this article from the function,load and system security aspects has carried on the test to the system,the test results are given.The system is in operation for more than a month after the teacher user and student users visited the teachers and learning of the system evaluation.And compared before and after the operation of the system in teaching and learning the difference.This paper is the analysis of the existing problems of current computer network aided teaching system,according to the characteristics of "computer basis" course,combining the learning style of educational theory,teacher and student users according to user demand,the application of many advanced computer technology,has realized the design and implementation of a computer aided teaching system.
