Automatic question bank question forming and difficulty real-time updating method

Abstract

The invention relates to an automatic question bank question forming and difficulty real-time updating method, comprising the steps: collecting exercises; performing difficulty grading; creating a question bank; when test paper needs to be output, extracting the exercises from the question bank according to the question types and difficulty in test paper and generating the test paper; updating thedifficulty of the exercises in the question bank according to the question answering situation of the test paper, wherein the difficulty grading comprises preset difficulty grading during exercise collection and automatic difficulty grading according to exercise test paper and accuracy; when a preset difficulty grading result is different from an automatic difficulty grading result, performing variance calculation between the preset difficulty grading result and the automatic difficulty grading result, and selecting a difficulty interval with the minimum variance as a result. According to themethod, difficulty setting and real-time updating are carried out on the test exercises in the question bank, so that the difficulty of the exercises can be controlled in the test paper composition process, and the control on the overall difficulty of the test paper is improved.

Description

technical field [0001] The invention belongs to the technical field of automatically grouping questions in a question bank, and specifically relates to a method for automatically grouping questions in a question bank and updating the difficulty in real time. Background technique [0002] Under the existing technology, most of the question banks have not realized the division of the difficulty coefficient of the questions, and the teacher can only randomly select questions from the question bank to form a test paper of varying difficulty. A small part of the question bank realizes the difficulty classification of the questions. After the questions are graded, the system can automatically and randomly select several questions of varying difficulty to form a set of test papers. But in fact, the difficulty of the exercises in this kind of question bank is also subjectively judged and entered by the question bank input personnel, and the system randomly selects questions without ...
