Application Of Campus Online Evaluation System In High School Informatics Competition Teaching

In recent years,the Informatics Olympiad has been continuously developed and promoted in middle schools,and the evaluation system is an indispensable auxiliary tool in the informatics competition.At present,there are two kinds of evaluation systems used in informatics competition courses,one is the open online evaluation system;and the other is the campus online evaluation system built locally.The campus online evaluation system is constructed by the teachers of school,and the teachers are the managers of the website,which is not only convenient for the teachers to manage the students,but also improve the students’ efficiency of solving problems.In order to improve the performance of school informatics competition,it has certain theoretical and practical significance to study how to efficiently use campus online evaluation system to assist the teaching of informatics competition.Through the research on the curriculum system of informatics competition in high school and the examination papers of informatics competition in the last 12 years,this paper defines the knowledge category of informatics competition.Through the analysis of the relevant data of the campus online evaluation system,it is found that the campus online evaluation system adopts the framework of B/S,with Linux operating system,Apache Web server,My SQL database and PHP scripting language as the core,with strong compatibility and high developability.This paper chooses HUSTOJ as the core of the campus online evaluation system,designs the question bank,homework,competition,forum,ranking and other functions,and constructs the campus online evaluation system database.In order to enhance the relationship between teaching and evaluation system,the examples and exercises are carried out around the system item bank.In order to enhance the teachers’ understanding of the students,the exercises are put into the special homework module,and turn on the code similarity detection function to prevent students from plagiarizing.In order to improve the efficiency of students in solving problems,the function of item bank label is added to enable students to quickly search for suitable questions.In order to improve the auxiliary effect of the campus online evaluation system,the problems and suggestions encountered by teachers and students are collected,the function and item bank are constantly improved and updated.This paper analyzes the situation of the three grade students who not using the campus online evaluation system,using the newly constructed campus online evaluation system and using the improved campus online evaluation system.Including four aspects:(1)learning progress(2)problem solving efficiency(3)test results(4)competition results,and explores the influence of campus online evaluation system on the teaching of informatics competition.In this paper,according to the actual teaching needs of the school,a campus online evaluation system is designed and completed.Through the tracking and analysis for many years,the results show that the campus online evaluation system has played a positive role in the teaching of informatics competition,which is mainly reflected in two aspects: teachers’ management of students and students’ practice.After using the campus online evaluation system,the overall level of the students has been greatly improved,and the final competition results have also improved.At the same time,the students who have studied the informatics competition in high school not only improve their learning ability,but also have strong professional advantages compared with other non-competitive students in the further study.
