Research And Application Of Web-based Exercise Evaluation System

Computer-Aided Instruction (CAI) has become not only an important element of teaching process, but also an important means to improve the quality of teaching, so full playing the advantages of computer-aided instruction has special significance. Current national educational institutions have adopted CAI technology, and combined CAI with other technologies to form a new generation of intelligent computer-assisted teaching system. Exercise evaluation system is an important part of the assisted education system, it is an important method for teachers to grasp learning status of students and guide purposefully , and for students to realize their degree.Because of the differences of learning support environment and methods of evaluation, Exercise evaluation system has the different practice type and evaluation results, but of various traditional evaluation methods , the common methods are average method and the critical incident method, they can make up for the deficiencies caused by a qualitative analysis To some extent, but they are not enough to reflect the evaluation of the fairness and objectivity, so that they can't fundamentally exert the guiding and encouraging role of the evaluation. Fuzzy Comprehensive Evaluation Method provides a powerful tool for quantitativly evaluating studies of practice.Exercise evaluation system is established based on fuzzy comprehensive evaluation method in this article to improve the quality of teaching assessment, teaching strategies and supporting teaching evaluation system.It collect data of completion time of exercise via computer ,so the evaluation result is more objective and more accurate than in traditional methods. The evaluation system, first, collect evaluation factors data (such as accuracy, completion time)via computer, then, produce evaluation results of exercises through using Weighted average algorithm of fuzzy comprehensive evaluation method to objectively reflect the effect of practitioners'exercises.It provide reference and practical basis to improve curriculum design of network-education, structure of the service environment,and construct of the evaluation systemThe article first describes the background of exercise evaluation system, as well as domestic and international research status; then discussed the relevant theories of exercise evaluation system, including the Java language, and its new technology SSH, and based theory of the fuzzy comprehensive evaluation algorithm; then carried out analysis and design using uml, presents a solution based on fuzzy weighted average algorithm of fuzzy comprehensive evaluation; then the test have been carried out for the system model ,and evaluation results are given. Finally, the analysis and evaluation of results, strengths and weaknesses of the system are summarized, and further research is made.
