Test question automatic generation system and method

Abstract

The application discloses a test question automatic generation system (100) and a test question automatic generation method based on project models. The system can enable each project model to be analyzed into a plurality of different test questions, and uses a main body to mark and inquire the project models and the constraints for forming a test paper; the system can analyze of the discriminability of each project model and provide feedback information from various aspects based on the results measured of the tester.

Description

technical field [0001] The invention relates to a system and method for automatically generating test questions, and more specifically, the invention relates to a model-driven system and method for automatically generating test questions. Background technique [0002] Test questions have many effects on improving the quality of teaching. Well-designed test questions can not only accurately evaluate the cognitive level of the testees, but also help them broaden their thinking and improve their knowledge structure. If the test item is exposed for some reason (such as appearing in an exam), its value will drop sharply, and its reuse often cannot test the true level of the testee. Therefore, for a realistic examination system, building a large-scale test question bank is crucial, which is also a significant overhead. In order to improve the efficiency of designing questions, researchers have proposed a variety of methods for automatically generating test questions. [0003] Ch...

Problems solved by technology

[0006] However, the knowledge points that the project model can test largely depend on the expressiveness of the language that expresses the parameter constraints. When the relationship between parameters cannot be expressed by the constraint language of the project model, such questions cannot be generated by the project model.

For example, the topic of associating a communication network topology graph with the shortest path of a certain node, the relationship between such parameters cannot be described in simple language - such as arithmetic operations and numerical value relationship - the topic of testing this knowledge point is also Unable to generate with item model

If the expression ability of the constraint language is enhanced, the difficulty of making project models will increase accordingly, until it is close to the difficulty of writing programs. It is too difficult for ordinary educators to make such project models
