Knowledge database, construction method and learning situation diagnosis system

Abstract

The invention discloses a knowledge database, a construction method and a learning situation diagnosis system. The knowledge database comprises a subject database data sheet, a knowledge point database data sheet, an examination database data sheet, a resource database data sheet, a student information database data sheet, a testing database data sheet, a testing student database data sheet and a test score database data sheet, and close relevance based on knowledge points is established in the sheets. The constructed database is applied to achieve intelligent test paper composition tests based on knowledge points, learning sticking points of test-takers can be diagnosed deeply in dependence on the relevance of knowledge points, furthermore, a route for consolidating learning knowledge is generated, and corresponding resources or test questions are recommended. Compared with the prior art, the knowledge database is advantaged in that the knowledge database is more complete, the knowledge points are related to one another more closely, through the learning situation diagnosis, the most fundamental sticking points can be captured, and scientific, comprehensive and systematic groundwork can be laid for the study of subsequent knowledge points.

Description

technical field [0001] The invention belongs to the technical field of educational informatization, and more specifically relates to a knowledge database, a construction method and a learning situation diagnosis system. Background technique [0002] With the development of the big data era, educational information technology has also made remarkable progress, among which online learning and personalized learning have become the focus of research. Now many universities and social education departments have set up online learning evaluation systems, and students can realize online learning and testing through computer networks. [0003] The diagnosis method of online learning mainly associates the test questions with the knowledge points, and judges the blind spots of the knowledge points according to the wrong answers, so as to guide students to strengthen their learning. Compared with the traditional learning methods, it improves the learning efficiency, but it still has the...

Problems solved by technology

[0003] The diagnosis method of online learning mainly associates the test questions with the knowledge points, and judges the blind spots of the knowledge points according to the wrong answers, so as to guide students to strengthen their learning. Compared with the traditional learning methods, it improves the learning efficiency, but it still has the following problems: ( 1) The current test questions and knowledge points only have a simple first-level relationship, and students fail to master this knowledge point, which is likely to be due to the fact that a certain knowledge point has not been mastered before, and the diagnosis results are one-sided and cannot be in-depth. Analysis of students' real learning problems

(2) The current learning diagnosis method mainly focuses on diagnosing students' mastery of the current knowledge point, without considering the impact of this knowledge point on other knowledge points, and the blind spot of a certain knowledge point may become a stumbling block in learning other knowledge. Some methods lack foresight and fail to prevent problems before they happen

(3) Although information-based education has become a trend, there are still offline learning and testing in many schools or regions. The current online learning diagnosis method cannot be applied to offline learning and testing, and there are limitations

(4) After the current learning diagnosis method helps to find the weak point of knowledge, it generally only guides students to consolidate this knowledge point, but there is a correlation between the knowledge points, often due to the lack of mastery of the previous knowledge point, which leads to the lack of understanding of the current knowledge point. Difficulties in understanding one point, which in turn leads to difficulties in learning the latter knowledge point
