[0003] With the continuous deepening of teaching content and the continuous improvement of teaching requirements, as well as the increasing need for assessment of the overall degree of students' knowledge mastery, the requirements for the quality of test papers are gradually increasing. Meet the needs of multi-angle high-quality test papers such as wide coverage of knowledge points, moderate difficulty of test questions, and uniform distribution of test question types

Embodiment Construction
[0014] The present invention will be further described below in conjunction with accompanying drawing and embodiment:
[0015] Forming the test paper is to select the questions that meet the requirements from thousands of test questions to form the test paper. Since each test question has multiple attributes, this is the solution of the so-called multi-objective problem. Since the multi-objective problem does not necessarily have a solution, even after traversing all the test questions in the test question bank and trying all possible combinations, It is also impossible to find a set of test papers that meet the user's soft index requirements. Therefore, we should not freeze the conditions in the process of forming test papers. Instead, we should perform a limited number of iterations based on the principle of optimizing the goal as much as possible, so that the obtained The test paper should be as close as possible to the needs of users.

The invention discloses a test-paper generation method based on a genetic algorithm. The method has functions of automatically extracting test questions and generating test paper. By using the test-paper generation method based on the genetic algorithm, the test paper is generated, so the electronization and automation of test-paper generating operation can be realized, burdens on a teacher are reduced, the teaching efficiency of the teacher is improved, and teaching quality is evaluated truly and objectively; and by the test-paper generation method based on the genetic algorithm, indexes such as test type, difficulty, discrimination and knowledge point distribution can be balanced relatively, user requirements can be met to the largest extent, and teaching management is more scientized and standardized.
Description
technical field [0001] The invention relates to a method for automatically generating test papers, and more specifically, the invention relates to a method for forming papers based on a genetic algorithm. Background technique [0002] In the field of education, examination is an important link in the whole teaching process. It is an evaluation of the knowledge and ability of students, and it is also an educational measure to measure the quality of teachers' teaching effects. In the previous exams, there were many problems in the way of organizing papers. The traditional way of making papers mainly relies on the teacher's focus on knowledge points to collect and select test questions to complete the compilation of test papers. Due to the interference of various human factors such as proposition content and scoring standards, it lacks universal comparability, test reliability and validity. lower. The use of computers to form test papers can not only save valuable time in the...
