Test Paper System Design And Implementation

A test item bank and computer automatically generating system of test papers is an efficient means of standardized selection of talents and objective evaluation of teaching, which embodies the principle of separation between teaching and testing, and provides a direction for future test paper giving. At the same time, the system can reduce a great deal of the periodically repeated work, and helps improve teaching.This paper is concerned with the setup of a test item bank and the design and completion of an automatically test paper generating system. At first,it introduces some item bank theories and connected terminology, including the basic characteristic and assignable requirements for the quality of test paper. The system can handle the item bank of various courses and different types of test questions. It can store and output test questions including graphs, images, tables, and formulae. Moreover, it guarantees security to a certain degree. The paper mainly deals with the process of selecting questions from an item bank and organizing a test paper, and points out difficulties confronted and ideas of coping with them, analyzes some strategies for test paper organizing based on these ideas. At last, considering the particular condition of a school, the paper decides on a strategy, describes its algorithm, and indicates the concrete source code for the key points of the algorithm. Based on this algorithm, the questions of a test paper can be distributed as evenly as possible according to different chapters. Based on this algorithm, repetition can be avoided to the best when more than one test paper needs to be generated, and at the same time, questions can be allotted reasonably and its difficulty degree up to standard. To say"to the best", it means that the system can employ a strategy which meets the organizing requirements to the best to ensure generating a complete paper, to the highest degree avoiding any failure of test paper organizing. Therefore, the efficiency of test paper organizing and the quality of the generated test paper improve a great deal. The paper also makes a test and analysis of the results from this algorithm.In addition, it puts forward a corresponding solution for the further requirements of this organizing algorithm.Finally, it summarizes the features and originality of this system and the test paper organizing algorithm, and points out the improvements needed in the future.
