Description

Technical Field

[0001] The present invention relates to the technical field of data analysis and processing, and specifically to a learning ability assessment method and system based on AI for personalized data analysis of students. Background Art

[0002] Learning power is the three elements of learning motivation, learning perseverance and learning ability. Learning power refers to the comprehensive manifestation of the motivation, perseverance and ability of a person, an enterprise or an organization to learn. Learning power is the ability to transform knowledge resources into knowledge capital. Learning power refers to the comprehensive manifestation of the motivation, perseverance and ability of a person, an enterprise or an organization to learn. Learning power is the ability to transform knowledge resources into knowledge capital. The learning power of an individual not only includes the total amount of knowledge, that is, the breadth of personal learning content and the degree of openness of the organization and the individual; it also includes the quality of knowledge, that is, the comprehensive quality, learning efficiency and learning quality of the learner; it also includes its learning flow, that is, the speed of learning and the ability to absorb and expand knowledge; more importantly, it looks at its knowledge increment, that is, the degree of innovation of learning results and the degree to which learners transform knowledge into value. Organizational learning power is a concentrated manifestation of people's innovation ability and can be directly transformed into innovation results. It advocates that team learning is more important than individual learning. The team has the ability to learn as a whole. Information and knowledge flow freely and are highly shared within the group. Team learning is not only a process of communication and exchange of ideas among team members, but also a process of seeking consensus and unified action, thus generating the team's "creative tension". In the field of education, how to accurately evaluate students' learning ability is a very important reference factor for implementing personalized teaching goals. Traditional student learning ability evaluation simply judges students' learning ability by the scores of students' answers at the same time through test questions. However, learning ability includes learning motivation, learning perseverance and learning ability. Test questions can only simply test students' learning ability, and cannot make a comprehensive judgment on students' learning motivation and learning perseverance. At the same time, in the learning ability test stage, only focusing on students' answering scores and not considering students' answering time cannot scientifically test students' learning ability.

[0003] The Chinese invention patent application with publication number CN114491050A discloses a learning ability assessment method and system based on cognitive diagnosis, which obtains the user's answer record, performs labeling preprocessing on the user's answer record, obtains the answer record with label and the answer record without label; clusters the answer record without label according to the answer record with label, obtains the label of all the answer records; inputs all the answer records and their labels into the cognitive diagnosis model, and the cognitive diagnosis model outputs the correct probability of the user's answer, and evaluates the user's learning ability according to the correct probability of the user's answer. The present invention takes into account different types of answer information, marks the answer record, clusters the answer record without label and the answer record with label, and inputs the clustering result into the traditional learning diagnosis model to complete the evaluation of the user's learning ability, makes full use of the large amount of different types of data information contained in the user's answer record, and improves the accuracy of the cognitive diagnosis model. However, the above technical scheme only considers the evaluation of learning ability and does not consider the comprehensive scientific evaluation and analysis of the learning motivation and learning perseverance of the learning ability evaluation user. Summary of the invention

[0004] 1. Technical issues to be resolved

[0005] To solve the problem that the traditional student learning ability assessment simply judges the student's learning ability through the test questions and the scores of the students' answers at the same time, however, learning ability includes learning motivation, learning perseverance and learning ability. The test questions can only simply test the student's learning ability, and cannot make a comprehensive judgment on the student's learning motivation and learning perseverance. At the same time, in the learning ability test stage, only focusing on the student's answer score, not considering the student's answering time, cannot scientifically test the student's learning ability. To achieve the above comprehensive and scientific assessment of learning motivation, learning perseverance and learning ability, improve the accuracy of learning ability assessment, and truly test the student's learning ability.
