Embodiment 1

[0033] Knowledge labels and quantification methods for knowledge points in the question bank. Take the single-choice questions in the national college entrance examination questions in a certain year as an example:

[0034] The motion of the high-speed train in the start-up phase can be regarded as a uniformly accelerated linear motion with an initial velocity of zero. The kinetic energy of the train in the start-up phase is:

[0035] A. proportional to the time it elapses

[0036] B. proportional to its displacement

[0037] C. proportional to its speed

[0038] D. proportional to its momentum

[0039] In the analysis, we mentioned that multiple-choice questions belong to the type of multi-knowledge points, and should be labeled according to each knowledge point in the question bank. In this question, the stem of the question is related to uniformly accelerated linear motion, and the main investigation is the law of uniformly accelerated linear motion, so it should be...

Embodiment 2

[0052] A solution for intelligently combining training questions from the intelligent question bank for learners. For example, a student needs to practice fact-level knowledge of the "motion" part of physics to figure 1 For example, the label can be extracted from the question bank according to the label j =1, from i =1 to j =6 questions are used for practice. If you need to practice the application of the "sports" part, you can extract it from the question bank according to the label i =3, from j =1 to j = 4 questions to practice. And if you need to practice the ability to analyze the "law of motion", you can extract from the question bank i =4, j =3 questions to practice.

Embodiment 3

[0054] A solution for intelligently grouping questions from the intelligent question bank. According to the goal of the exam, such as the unit test, it is set for students to master and apply the content of this unit, which can be figure 1 The comprehensive difficulty is set to 7, so the questions can be extracted from the exam questions with S=7. At this time, the number of questions at different levels can also be specified, such as the number of questions at cognitive levels A, B, C, D, E, F, or unlimited. When analyzing the test papers obtained by such an intelligent way of grouping questions, teachers and students can clearly recognize the advantages and disadvantages of knowledge and cognition, optimize the teaching and learning plan, and be targeted for the next step of learning.

Abstract

The invention discloses a hierarchical label of a question bank and an intelligent application method. The method comprises a knowledge hierarchical tagging and quantification method, a difficulty quantification method based on knowledge point hierarchical tags, an intelligent question bank question composition method based on the difficulty quantification method based on the knowledge point hierarchical tags, a tag processing method for different question types, an intelligent question composition method based on an intelligent question bank and an intelligent test paper analysis method. According to the method, the knowledge points are labeled and quantized according to knowledge levels and cognitive depths, so that the knowledge points are hierarchical and have determined quantized values; based on the question bank of the tagged knowledge points, intelligent extraction of the knowledge points can be realized, and the question bank is further enabled to have intelligence. Based on an intelligent question bank, intelligent test paper composition and intelligent test paper analysis can be realized according to knowledge point labels and according to a use target, so that a user ofthe question bank masters the overall situation and individual situation of learners according to the labels and formulates targeted teaching and learning strategies.

Description

technical field [0001] The invention belongs to the fields of knowledge quantification, intelligent learning and education and training, and specifically relates to a labeling system for a question bank based on knowledge points and hierarchical classification, and an application method of the labeling system in building a question bank, intelligent teaching and intelligent learning. Background technique [0002] Intelligent analysis based on big data will provide the possibility for intelligent learning. With the development of big data analysis and application technology, intelligent teaching and intelligent learning will enable learning to be targeted. As a basic data, the question bank plays an important role in the application of intelligent teaching and intelligent learning. A question bank with a reasonable system structure and clear knowledge labels is essential for both intelligent teaching and intelligent learning. [0003] Generally speaking, a question bank is a...
