[0031]According to the applicant's research, it is found that the existing cognitive diagnosis models only diagnose for a single test. However, with the deep integration of education and big data, today's educators are not satisfied with judging the state of learners' knowledge ability through a single diagnosis, but hope to conduct comprehensive analysis and mining on the data of staged and continuous tests To achieve accurate and stable diagnosis of students' deep knowledge structure, skills and methods. For the learning data of the whole learning process, the existing cognitive diagnosis model will have technical problems such as computational complexity and attribute conflicts, and no better solution has been proposed so far. In order to solve the above problems, the first embodiment of the present invention provides a temporal cognitive diagnosis method.

Embodiment approach

[0032] Please refer to figure 1 , figure 1 It is a flowchart of a sequential cognitive diagnosis method provided by the first embodiment of the present invention. As an implementation manner, the specific steps of the sequential cognitive diagnosis method are as follows:

[0033] Step S10: Obtain the learner's current diagnostic test data and previous diagnostic test data.

[0034] Step S20: Obtain a current diagnostic test result based on the current diagnostic test data and the preceding diagnostic test data.

[0035] It should be understood that before step S10, a domain knowledge model for cognitive diagnostic testing needs to be created. The domain knowledge model mainly includes expert knowledge base (knowledge map) and subject diagnosis resources (including diagnosis test question bank and diagnosis test paper bank, etc.), both of which are completed by subject experts. Guided by cognitive theory, subject experts select matching test questions from the resource libr...

[0067] In order to cooperate with the temporal cognitive diagnosis method provided in the first embodiment of the present invention, the second embodiment of the present invention further provides a temporal cognitive diagnosis apparatus 100 .

[0068] Please refer to Figure 5 , Figure 5 It is a block diagram of a temporal cognitive diagnosis device provided by the second embodiment of the present invention.

[0069] The sequential cognitive diagnosis device 100 includes a diagnostic test data acquisition module 110 and a diagnostic test result calculation module 120 , as an implementation, the sequential cognitive diagnostic device 100 may also include a model training module 115 and a remedial route planning module 130 .

[0070] The diagnostic test data acquisition module 110 is configured to acquire the learner's current diagnostic test data and previous diagnostic test data.

[0071] The model training module 115 is configured to use the training set to train the sequ...

Abstract

The invention provides a sequential cognitive diagnosis method and apparatus, which relates to the technical field of educational testing. The sequential cognitive diagnostic method first acquires thecurrent diagnostic test data and the preamble diagnostic test data of a learner, and then acquires the current diagnostic test results based on the current diagnostic test data and the preamble diagnostic test data. The sequential cognitive diagnosis method considers the limitation and instability of the cognitive diagnostic results of a single test, screens the preamble diagnostic test data, extracts the effective preamble information, inputs into a sequential diagnosis model based on the effective preamble information and the current diagnostic test data to obtain a final current diagnostictest result, thereby improving the accuracy and comprehensiveness of the cognitive diagnosis.

Description

technical field [0001] The present invention relates to the technical field of educational tests, in particular to a time-series cognitive diagnosis method and device. Background technique [0002] With the rapid expansion of the scale of modern teaching, teachers cannot accurately know the knowledge mastery of each learner when teaching dozens or even dozens of hundreds of learners, so they cannot grasp the individual and overall knowledge level of students. The teaching method and teaching content are adjusted according to the situation, resulting in poor teaching effect. At the same time, the traditional test / examination only uses the total score of the test as the evaluation index, which is too general and general. Now people not only require the test to be evaluated at the level of the total score, but also hope to go deep into the level of cognitive processing within the learner. The Cognitive Diagnostic Model (CDM) provides the possibility to construct the cognitive ...
