Embodiment Construction

[0069] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0070] The present invention uses the learning behavior data collected from the online learning platform and the basic statistical data and achievement data of students collected from the educational affairs management system, and then based on the multilayer perceptron (MLP) algorithm and the C4.5 decision tree algorithm, constructs two The prediction model of the stage is formed, and then the early warning model of the final academic performance is formed.

[0071] In the first stage, a success prediction model (the prediction target of the model is the students who will pass the exam) and a fail prediction model (the pre...

Abstract

The invention belongs to the technical field of education and teaching, and discloses an early warning method and a system for students' achievement based on educational data mining. The method comprises: data obtaining; data preprocessing; partition of data sets; constructing of forecasting model of the first stage; constructing of the second stage prediction model;and forecasting of results. Theinvention obtains the learning behavior data of the students for a period of time, three prediction models in two stages are constructed to predict the students early and accurately, so that teacherscan teach students pertinently according to the predicted results. In the first stage, multi-layer perceptron algorithm is used to construct the success model to predict the students who pass the examination and the fail model to predict the students who fail the examination. The second stage is based on the two models of the first stage and their derivative variables, and then the decision treealgorithm to is used generate the final early warning of online students' performance, to early predict the learning results of students.

Description

technical field [0001] The invention belongs to the field of education technology, and in particular relates to an early warning method and system for student achievement based on education data mining. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] With the continuous development of Internet technology and the increasing number of online learning platforms, learners' learning methods have also shifted from traditional offline learning to online learning. One of the advantages of the online learning platform is that it can record the learning behavior traces of the learners on the platform in the form of logs, which provides a data basis for teachers and administrators to understand the learning process and learning results of students; at the same time, with the education data The continuous evolution of mining technology provides technical support for teachers and managers to deeply analyze the le...
