Development And Research Of Online Judge System For Middle School Informatics Olympiad

At present,the development of information technology education in primary and secondary schools in China emphasizes the development of programming training for all students,and carries out computer education with the goal of the formation of computational thinking and the cultivation of problem-solving skills.As one of the five major Olympic discipline competitions in middle school,National Olympiad in Informatics is a direct and effective method for popularizing computer education for young people,and has become one of the ways to cultivate young people's innovative qualities.National Olympiad in Informatics combines theoretical learning and practical application,focusing on the ability of programming thinking to solve practical problems.The combination of Online Judge system and National Olympiad in Informatics can not only improve the efficiency of students' evaluation,but also reduce the teaching burden of teachers and reduce human error,which effectively improves the effect of students' self-learning to a certain extent.Online Judge system is now widely used in the training and selection of university programming in the world.The platform construction of Online Judge system of National Olympiad in Informatics remains to be further studied.The Online Judge system is aimed at teachers and students who participate National Olympiad in Informatics.The teacher organizes online evaluation and assignment based on the system,and builds a question bank based on the teaching progress.On the basis of the correct result of the pursuit of the program,the student user needs to examine more about the solution to the problem and the method.This paper comprehensively analyzes online evaluation systems at home and abroad,through the preliminary planning and design,the theoretical knowledge of system development and the practice of related technologies.According to the current Olympic in Informatics,the design and implementation of Online Judge system for Olympic in Informatics.It solves the problem of timely feedback of evaluation information,self-mastered question bank and secondary development and optimization in the process of students' self-learning.What's more,it also gives a reference to the people who design and develop Online Judge system relatively.
