The Design And Implementation Of Online Marking System

In recent years,with the increase of the national demand for high-quality and innovative talents,all levels of educational examinations have started to attach more attention to the evaluation of students' innovative consciousness and practical ability.Therefore subjective questions,innovation-type questions and divergent thinking questions increase,which puts forward higher requirements of various markings of the subjective question in all kinds of examinations.Marking error control,fractional statistics,report generation,test score rate and marking efficiency must be accurate and efficient.With the rapid development and large-scale popularization of computer technology,network technology and image processing technology,all types of Web-based examination marking system arise subsequently.In the process of online marking,students' test papers and answers are separated and then the answers are digitalized by means of high speed scanning equipment and stored in the server.Hence In this way the objective questions are marked automatically.The marking of subjective questions is relatively more complicated.Firstly,the system cuts and processes the answer pictures by using high-speed scanner,realizing the separation and identification of each question;secondly,the system sends questions stored to teacher's personal terminals to help with their markings;thirdly,the whole process of marking is supervised by a group leader through a real-time monitoring system and the scores given by the teachers who correct the papers are averaged according differential control principle set for this exam;finally,the system introduces a mechanism of trail assessment,reassessment,arbitration which effectively avoids marking errors owing to the negligence of some teachers,hence effectively the fairness and justice of an examination are guaranteed.Based on the investigation of existing online marking systems and school examination grading work and the exploration of state educational policies in the new situation,this paper focuses on the design and implementation of an online marking system which is developed strictly according to the software development standard and process.First,it implements the design and development of a marking system by selecting the J2EE and SSH frameworks and summarizes the description of the related techniques after analyzing the domestic and foreign development situation of online marking system and making a comparison among the currently popular software development techniques;second,it introduces the feasibility of the system development and elaborates the system requirements;third,it designs and develops the main function module of the system;then,it designs a variety of test cases from different angles to test the system which has achieved the expected function.Finally,online marking system on the existing problems and future development are described and discussed.After research and development complementary system,we should continue to follow up on new technologies and methods of teaching law.Designed for the development and mining module system data integration platform for all kinds of data,using the latest cloud computing and data mining technology,analysis and forecasting of development of education teaching,teaching to avoid the problems that may arise,to predict the future of education and teaching development,so as to better promote individualized,personalized development of new teaching model and teaching modern management reform and development.
