Test paper quality detection method, system and device and storage medium

Abstract

The invention discloses a test paper quality detection method, system and device and a storage medium, and can be applied to the technical field of education information. According to the method, the first probability matrix for the preset student group to correctly answer all exercises and the second probability matrix for the preset student group to correctly answer all knowledge points at the next moment are respectively predicted through the historical answer record information of the preset student group, and the exercises corresponding to the target test question are acquired from the exercise set as the simulation test question; predicting a first use effect of the preset student group on the simulation test question according to the first probability matrix, predicting a second use effect of the preset student group on the target test question according to the second probability matrix, and determining a third use effect of the target test question according to the first use effect and the second use effect; and determining the detection result of the test paper corresponding to the target test question in combination with the simulation test question, so that the test result can be predicted in a prediction mode before the test, and the detection result of the target test question is obtained according to the predicted test result.

Description

technical field [0001] The invention relates to the technical field of educational information, in particular to a test paper quality detection method, system, device and storage medium. Background technique [0002] Examination is an important activity in teaching work, which reflects the learning effect and shows the difference in knowledge level among students. At the same time, the examination is also the hub of the continuation of teaching activities, which is very important for students to graduate and enter higher education. The test paper is the carrier of the test, and the quality of the test paper determines the quality of the test. In related technologies, the quality of the test paper is checked by the test result, but the test result cannot be known before the test paper is used. At present, most of the test paper generation methods are based on supervised question bank retrieval and multi-objective optimization, relying on the "difficulty label" in the test q...

In related technologies, the quality of the test paper is checked by the test result, but the test result cannot be known before the test paper is used

At present, most of the paper generation methods are based on supervised question bank retrieval and multi-objective optimization, relying on the "difficulty label" in the test question bank. Due to the subjective bias of the label and the uncertainty of the organization of the test questions, the difficulty, Indicators such as discrimination are uncontrollable, so the quality of each generated test paper cannot be guaranteed, and the effect is unstable
