Design And Implementation Of Intelligent Question Bank And Examination System

Considering the PISA test results and investigation reports of 2012 and 2015,it can be seen that Shanghai were ranked first in the world in 2012,and scores in some subjects far exceeded those of other countries(regions).The quality of K-12 education is still competitive under a worldwide comparison.However,this is based on the results that students spend more time on homework than students from other countries.Under the circumstances,excessive practice and repetition seem to be unavoidable issues.How to reduce the burden on teachers and students has become an important issue?On the other hand,in 2015,the three other cities from China involved in the test.The overall decline in the world rankings seems to indicate a gap in the quality of interregional education.All four provinces and cities are on the eastern coast,and if we considering the broader western region,Is the gap in education quality even greater? Education equity is an important indicator in education,and it is also an important social issue.During the era of the Internet,Internet education has also risen rapidly,led by foreign company like Mocha and Khan Academy.In the development of the mobile Internet and the rapid spread of broadband in China,various types of Internet education products have emerged.With the support of national policies,the rapid growth of GDP,and the support of various conditions for the development of new technologies,many related products have emerged in the K-12 education,among which the question bank system is a key project.The question bank system can be divided into teacher-involved and auto question bank systems.The teacher involved system need teacher to select items from the question bank and arranges questions for students.The auto question bank system does not require teacher in the selection procedure.After the students enter the system,they can select related question banks to do the questions.The system assigns relevant questions according to the students' ability,and dynamically adjusts the questions that should be placed along with the results of the students' answers.After the students answer the questions,the system will count the student's answer and send the results back to the students and teachers.This study is divided into three parts:(1)Designing and developing the test database system;(2)Presenting the question bank system intelligence program;(3)Presenting the question bank system's involvement in teaching and learning activities.Based on the needs of the teachers and students,the system has three parts: the front desk,the back office,and the database.The front desk have a teacher side and a student side,and the teacher side can be a teaching tool.Provides functions such as group management,title entry management,job volume management,job roll layout,job volume correction,score query,and comment entry management;student side can provide students with functions such as joining groups,writing assignments,and querying job reports.Teachers can choose the teaching topic,the system automatically according to the teacher's selected questions match the relevant consolidation volume and related volume.The system can give the feedback instantly to the teacher before the next class,as a reference for teachers to design course content and teaching materials and teaching methods.In terms of the intelligence of the item bank system,this study proposes two parameters related to the “student ability index” and the “test difficulty index”.The student's results in the question bank use the given difficulty index to give the objective difficulty of each question.The index,then using the calculated difficulty index of the test item to match the student's answer result,uses the student ability index given function to calculate the corresponding student ability index for each student.Then,according to the student ability index,students with similar abilities are divided to calculate the title of the largest test difficulty index to which the student ability index in this area can answer,and the matching relationship table between the student ability index and the test difficulty index is completed.When the students logging,the system can select the appropriate questions from the bank of questions according to such comparisons.In the process of the students' answers,the student ability index adjustment function is used to dynamically correct the student ability index.In this way,the question bank system can be intelligent zed only by the interactive relationship between the system and the students,and the questions are placed according to the needs of the students.After completing the system,the researchers collaborated with the school teachers.Based on the results,each test item in the bank is given the difficulty index of the test item according to the intelligent design.The participating students are given the student ability index,and the system also has a simple match.In the process of study,students and teachers did achieve the initial goal of the original system design,allowing students to immediately learn the wrong questions after answering questions,and provide teachers with immediate feedback on student answer results as a reference for instructional design.The intelligent question bank system based on new technology development can provide several help in teaching.1.Reducing the burden on teachers and students,improving the workload of teachers,providing teachers with more accurate teaching information,improving student learning efficiency,and personalized learning as a self-recording of learning and teaching.2.Provide quality education sources,maximize the use of educational resources,assist teachers in development,and balance regional education differences.3.The use of big data in question bank system to discover the original and unknown possibilities,assist in information investigation and implement teaching research.
