Researchand Development Of C Language Public Course Online Examination System Based On JSP

Internet technology is becoming more and more mature and has penetrated into all walks of life.In the education industry,from teaching mode to management mode,from in-class learning mode to after-class learning mode,from homework mode to exam mode,Internet technology has played a certain role.With the support of Internet technology,new forms of education keep emerging,such as moocs,micro-courses,online teaching,online exams and so on.And one of the most important parts of education is the exam.The traditional examination way is in the fixed place,under the artificial surveillance,carries on the written examination.This will cost considerable manpower,material and financial resources.In order to improve the efficiency of the examination,save the cost of all aspects,reflect the fairness of the examination,the emergence of examination system based on Internet technology.In the process of the development of the examination system,the algorithm of test paper grouping has been greatly improved.The examination system mostly adopts many methods such as genetic algorithm based test paper grouping,backtracking cost based test paper grouping,random extraction algorithm based test paper grouping,intelligent test paper grouping and so on.However,the test paper grouping problems mentioned above based on different algorithms have encountered many problems in the work of the test system,such as not changing the immobilization problem in the traditional test paper grouping problem,mistakenly believing that the types of questions with the same difficulty coefficient have commonness and screening,and the accuracy is still not good enough.Therefore,in order to better play the role of online examination system,it is of great significance to study the development of the examination system based on the question of test paper grouping.In view of the shortcomings of the above test paper grouping problems based on different algorithms,this paper proposes a test paper grouping examination system that can reasonably judge students' ability level,namely the test paper grouping problem scheme based on the analytic hierarchy process.This method uses analytic hierarchy process(ahp)to analyze the difficulty level of each type of test questions according to the overall answer level of students.Then the test paper is published by using the test paper grouping algorithm,and the test paper is generated automatically.At the same time,the use of analytic hierarchy process based volume,a good solution to understand the space too wide,the optimal value of too many problems,to avoid falling into the local optimal,algorithm complexity too high dilemma.Through the weighted construction of different schemes in different layers by the analytic hierarchy process(ahp),it can well converge and reduce the burden of the system's global search test questions,providing the best test questions for the test paper grouping,and improving the efficiency.This paper is based on the education planning project of jilin province,? research on the training mode of computer applied innovative talents based on CDIO?,and compiled in combination with the C language public curriculum reform of jilin jianzhu university and the revision of the training program of 2016 edition.Now jilin jianzhu university has expanded the number of undergraduate students,and the number of C language public courses has also increased.In order to adapt to the development of new forms,change the traditional teaching mode,we need to develop online examination system based on JSP.The online examination system not only realizes the paperless,but also makes students not subject to the constraints of time and space.The examination can be conducted at any time and place.At the same time,it also facilitates teachers' marking work and improves the efficiency and standardization of examination work.The online examination system has become an important branch of intelligent education.Under the support of JSP technology,the test paper grouping system based on the analytic hierarchy process is different from the test paper grouping system based on other algorithms.It involves complex factors comprehensively and can better automatically generate test papers in line with students' abilities.It has strong applicability and feasibility.
