Design And Development Of Students Online Test Data's Visualization System

With the rapid development of information technology in recent years,education informatization also presents an unprecedenting trend of development,and the innovation and change of education are having been pushed by the deeply integrated of technology.The development of big data technology can provide a new direction for education development,whether it is the collection and sorting of education information or the statistics,calculation and visualization of education data,so that the traditional teaching based on experience can be transferred to the precise and personalized teaching based on student data analysis.However,although in the aspect of education big data has a lot of research,but the fusion of technology and teaching is still not ideal,teacher to student's evaluation is still dependent on traditional way of teaching evaluation,such as test scores,accurate degree and its teaching and student's individuation degree is low,it is difficult to meet the requirements of The Times.Based on this,this paper learned that in the form of questionnaire survey,the current primary and secondary school stu.dents of the most widely used test data is limited to the test scores,rankings,pass,proficiency,etc.,most teachers use statistical analysis tools for the Office software and other special performance analysis system,which to improve teachers' teaching precisely,individualized teaching has no substantial help.In view of the above situation,this study analyzes the title attribute and explore in students' test what valuable data should be obtained as a starting point,to design and develop students online test data's visualization system.This system realized by teachers online editing test subject,to test the title tag,organizes the student to the online test and statistics of each label test data,which in turn generate visual chart,it is concluded that the teacher and the students test feedback reports.This system has three functions:the first is the teacher online edit test topic and add the label;Second,students conduct online testing;The third is the students online test data and feedback in the form of visual data generated report feedback to teachers and students respectively,the report also can be based on the statistics to the teachers' teaching and students' learning pattern of preliminary suggestions.During the study,first of all,the author read a lot of relevant research literature at home and abroad,of education on the basis of the data,data visualization,personalized learning and precise teaching background made detailed elaboration,and secondly,through the literature research and empirical research folly understand,analyzed the current status of primary and secondary school students test data analysis system of use,and summarizes the advantages and disadvantages,on the basis of the results of the analysis system functional requirements are obtained.Thirdly,based on the demand analysis,the system architecture model,the system development model and the functional module design and implementation are determined based on the software engineering theory.I chose the Eclipse PHP Studio development tool,combined with PHP technology,MySQL database technology,HTML5 technology,jQuery technology and chart.js plug-in,and realized the expected goal of this study.Finally,the system is tested in a small scale,which verifies the integrity and validity of the system,and discusses its existing problems and prospects for the future development of this research.The main conclusions of this study are:1.Precision teaching and personalized learning are not only the trend of The Times,but also the requirements of education development,and the practical needs of teachers and students in primary and secondary schools.2.Designed and developed a student online test data's visualization system,through the trial add title tags and student online testing,and generate feedback report such as functional testing,validation system usability and practicability,can achieve the conclusion of a requirement,can satisfy the needs of users,has strong practicability and realistic significance.
