Cognitive diagnosis method based on learner cognitive response model

Abstract

The invention discloses a cognitive diagnosis method based on a learner cognitive response model. According to the invention, the method comprises the steps: evaluating and / or predicting the cognition condition of a learner through a cognition reaction model, wherein the cognitive response model comprises a learner ability level, a learner effort degree, a learner knowledge level, a knowledge characteristic matrix, a test question characteristic matrix, knowledge weak item parameters, an inspection matrix and a result matrix, and a mutual compensation relationship exists between the ability level and the effort degree. Compared with the prior art, the cognitive diagnosis method provided by the invention has higher accuracy.

Description

technical field [0001] The present invention relates to the technical field of cognitive diagnosis methods. Background technique [0002] In the era of educational informatization, the popularization and application of online learning platforms enables learners to break through the constraints of time and space and acquire knowledge more conveniently and quickly. However, in the face of a large number of learning resources on the platform, how to assess the knowledge level of learners and provide learners with matching educational resources has become a serious problem facing online learning. The cognitive diagnosis model uses a mathematical model to describe the potential interaction structure between the learner's knowledge level, the knowledge characteristics of the test questions, and the answer results of the test questions of the learners. Knowledge attributes diagnose learners' knowledge levels. According to the diagnosis results, personalized educational resources ...

AI Technical Summary

Problems solved by technology

[0005] Although the above-mentioned technologies have improved the interpretability and accuracy of the cognitive diagnostic model by introducing high-level features such as "ability", they still lack the consideration of the factor of learners' acquired efforts, and learning The knowledge level of the learner is not only related to the innate ability level of the learner, but also greatly related to the degree of effort acquired, that is, the degree of effort and the level of ability should have a similar impact on the level of knowledge of the learner, and the two have a great influence on the level of knowledge. Influence effects can also compensate each other, therefore, the evaluation accuracy of the cognitive diagnosis model in the prior art is still insufficient
