Problems solved by technology

The scores added by this method are often not convincing enough to objectively measure the impact of each topic or each knowledge point on the total score of the student, and there may even be low-level mistakes in which the student's score exceeds the total score of the test paper

Abstract

The invention discloses a method and a system for estimating student scores in real time by using a machine learning model. The method comprises the following steps: acquiring historical learning dataand examination scores of students; performing machine learning model training by taking the historical learning data as an input feature and taking the examination score as a target, training a relationship between the input feature and the target, and constructing a score estimation model of the student; when the learning behavior data of the students with the scores to be estimated is obtained, according to the learning behavior data, utilizing the score estimation model of the students to perform real-time estimation of the examination scores, and obtaining an examination score estimationresult. According to the invention, the learning conditions and scores of students can be timely and effectively fed back to teachers or parents, the labor cost for estimating the scores of studentsin offline examinations, examination papers and other modes is saved, the score estimation efficiency is improved, and the learning interest and confidence of students are promoted.

Description

technical field [0001] The invention relates to the technical field of Internet education, in particular to a method and system for predicting student grades in real time using a machine learning model. Background technique [0002] At present, the only way to test students' grades is through offline exams and teacher corrections. This traditional method has many disadvantages: for example, it requires students to spend time preparing for the exam, and the exam itself takes about 2 days, which delays the time that should have been learned for other knowledge. Teachers are required to invigilate and correct test papers, which takes up a large part of the teacher's energy and reduces the time for teachers to teach and explain. The results of a certain test may be due to the status of the students themselves or some knowledge points not reflected in the test papers, etc., resulting in large fluctuations in the test results, and the results are not accurate and reliable enough....
