Study And Implement Of Automatic Test Paper Generation System Based On Genetic Algorithms

As an important section of teaching process, test has been increasingly concerned. How to generate a set of papers with high quality, detect the true level of learning and achieve an objective assessment of the students' learning abilities is a hard question for the teachers. To develop a test paper system which can evalute the teaching levels objectively is an important subject for the teaching reform.Purpose of this paper is to study and develop a set of constraints to the conditions set by the user automatically and quickly generate a set of high-quality papers, to check the students test the true purpose of learning ability. Automatic generation of efficiency and quality depends largely on the Question Bank questions arithmetic in the design and selection, so the main contents of this paper is the mathematical model and the test paper questions arithmetic. Specific as follows:1. Classical measurement theory as a basis for the main questions to study properties and constraints analysis, design a test paper a mathematical model.2. To the genetic algorithm test paper method for this test paper the mathematical model, based on traditional genetic algorithm design of the chromosome Algorithmic coding scheme; the initial population Algorithmic options; design of the test paper method The selection operator, crossover operator, the compiler operator; determine the genetic algorithm termination conditions; as well as the basic work Algorithmic process. Experimental results show that the test paper based on genetic algorithm strategy, the efficiency in the test paper and test paper test paper quality to meet the actual demand.3. This article also features automatic test system of modules and database design, the system's main function modules include:paper management, paper management, system management three functional modules, which include paper management:Questions in management (Questions in Add, modify, delete, etc.), knowledge point of management (knowledge points to add, modify, delete, etc.), difficulty settings, add questions, delete questions, modify questions, visit the functional module; paper management, including:automatic generation of test paper, manually generated paper, visit the paper modules; system management including:the role of management, user management module.
