System and method for promoting structuring of mapping knowledge domain by group study behavior

Abstract

The invention discloses a system for promoting structuring of mapping knowledge domain by group study behavior and a method. The system comprises an information extracting module, an individual mapping knowledge domain, a group mapping knowledge domain structuring module, a knowledge point atlas structuring module, and a feedback module. The system and the method are applicable to the teaching andonline study of middle and primary schools, students can build up a link of a knowledge point Ki and a theme knowledge point set that Ki affiliates {K1, K2, K3...Ki-1, Ki...Kt} and forms the individual mapping knowledge domain through operation of related contents of knowledge point during the study process of the knowledge point Ki; the knowledge link is expressed by a triple <concept, relation,property> form; the individual mapping knowledge domains of many learners are gathered to form a group mapping knowledge domain Gc; all triples in the group mapping knowledge domain are performed with reliability analysis, the triple failed to reach reliability threshold value is removed to obtain a knowledge point atlas Gk with authority of knowledge point Ki; experts can improve the formed knowledge point atlas; finally, the knowledge point atlas can provide feedback for the study of students.

Description

technical field [0001] The present invention belongs to the field of subject knowledge base construction, specifically, it is a system and method that utilizes learners' group learning behaviors to promote the construction of structured knowledge maps. On the one hand, the system and method utilize learners' group learning behaviors to implement The construction of knowledge ontology also promotes the knowledge structure of individual learners, which can be used in educational practice fields such as educational informatization, information technology and curriculum integration. Background technique [0002] Knowledge structure is an important concept in pedagogy. Piaget's constructivist theory, Bruner's subject structure theory, and Ausubel's cognitive structure theory all believe that knowledge structure is conducive to students' learning and knowledge application to varying degrees. The famous American educator Schwab proposed the concept of subject structure based on the...

Problems solved by technology

[0009] The technical problem to be solved by the present invention is: to overcome the learning limitation that current knowledge learning has no structure, and learners cannot communicate with knowledge points and knowledge point-related resources, and realize learners and knowledge points through ontology technology, associated data technology and canvas drawing technology. , The structuring and graphic representation of knowledge point associations, so that learners can see not only their own personalized knowledge map but also the group's learning map of the knowledge point; at the same time, according to the learner's personalized knowledge map And the analysis of group knowledge map, get the knowledge point structure map which is constantly updated, so as to promote the learning of learners
