Education and teaching evaluation system based on artificial intelligence blackboard and evaluation method thereof

Abstract

The invention discloses an education and teaching evaluation system based on an artificial intelligence blackboard and an evaluation method thereof, and relates to the technical field of big data analysis. The system comprises a database, a data acquisition unit, a query statistics unit, a comprehensive evaluation unit and a system maintenance unit; the data acquisition unit comprises a data acquisition module, a data preprocessing module and a multi-source conversion module; the query statistics unit comprises a query module and a statistics module; the comprehensive evaluation unit comprisesa decision tree module and a classification module; and the system maintenance unit comprises a user management module and a data management module. A large amount of data related to education and teaching and corresponding evaluation results are recorded through the system database, the decision tree algorithm is adopted to associate behaviors and results to construct the classification model, and the evaluation results are made for the preprocessed classification data according to the classification model, so that time and labor consumption of manual evaluation is avoided, and the educationand teaching evaluation accuracy and efficiency are improved.

Description

technical field [0001] The invention belongs to the technical field of big data analysis, and in particular relates to an artificial intelligence blackboard-based education and teaching evaluation system and an evaluation method thereof. Background technique [0002] Big data, or massive data, refers to massive, high-growth, and diverse information assets that require new processing models to have stronger decision-making power, insights, and process optimization capabilities. In "The Era of Big Data" written by Victor Meyer-Schönberger and Kenneth Cukeye, big data refers to the use of all data for analysis and processing without shortcuts such as random analysis. [0003] With the development of modern science and technology, there are more and more application fields of big data analysis, and the classroom has gradually bid farewell to the traditional blackboard and chalk teaching mode. More and more classrooms use capacitive touch technology to combine traditional handwri...

Problems solved by technology

[0006] The purpose of the present invention is to provide an education and teaching evaluation system and evaluation method based on an artificial intelligence blackboard, record a large amount of data related to education and teaching and the corresponding evaluation results through the system database, and use the decision tree algorithm to correlate behaviors and results to build a classification model , and make evaluation results on the preprocessed classification data according to the classification model, which solves the problem that the existing teaching evaluation is greatly affected by personal feelings and the evaluation is inaccurate
