Embodiment 1

[0024] Embodiment 1: We still take the height of Mount Everest as an example to illustrate:

[0025] The title is the height of Mount Everest ()? Since the database has not been updated, the value of the standard answer in the database is 8848.

[0026] At this time, a plurality of students input the answer 8844 as the answer R. The system records the answer and creates a wrong question table under the question directory of the student exercise database, and stores 8844 in the wrong question table;

[0027] When the system extracts the last 100 people who answered the question, it finds that the answer 8844 appears 74 times, and 8840 appears 5 times. At this time, two judgment questions will be generated. Is the height of Mount Everest (8844)? Is the height of Mount Everest (8840)?

[0028] Transfer the judgment question to the teacher's exercise database to find the subject attribute is geography, and the corresponding grade is the information of primary and junior high sc...

Embodiment 2

[0035] The topic is the total () large planets in the solar system? Since the database has not been updated, the value inside is 9.

[0036] And a few years ago, because many people filled in the answer 8, R=8 had entered the detection system twice, and both were rejected.

[0037] When the detection system finds that the answer 8 appears 28 times, it satisfies m>(n+1) 3 Time. At this time, a judgment question is generated: Are there (9) large planets in the solar system? It should be noted that m starts counting again after entering the detection system each time, and n takes the value of 1, 2, 3 and other natural numbers.

[0038] Transfer the judgment question to the teacher's exercise database to find the subject attribute is geography, and the corresponding grade is the information of primary and junior high school teachers, and add the judgment question to the question bank of qualified teachers.

[0039] Since this question has been mentioned many times, the number ...

Embodiment 3

[0043] Idiom fill-in-the-blank questions:

[0044] not at all();

[0045] The answer reserved in the original database is hang. The system counted the last 100 answers, and found that the number of times to fill in "结" was 4 times, and the number of times to fill in "狗" was also 4 times.

[0046] At this time, two judgment questions are generated: Is meticulous an idiom? Is not at all an idiom?

[0047] Transfer these two judgment questions to the teacher's exercise database to find the subject attribute is Chinese, and the corresponding grade is the information of junior high school and high school teachers, and add these two judgment questions to the question bank of different qualified teachers.

[0048] Due to the strong subjectivity of Chinese questions, the expected number of answers is set to 3 this time. "Is meticulousness an idiom?" This question has been judged correct by 3 consecutive teachers, and the answer of "gou" will be added to the answer library of the st...

Abstract

The problem to be solved by the invention is to collect the students' answers to fill in the gaps and find the frequent answers that are inconsistent with standard answers. Through a teacher's upgrading system in the system, interacting is performed without causing teachers' subjective attention; the answers that are inconsistent with standard answers and frequently occur are subjected to the secondary judging; if it is found that the answers can be regarded as correct answers, the answers can be added to a database to make up deficiencies in the existing database. To solve the above problem, the invention provides the on-line learning system with the automatic-correction function. As for a gap filling question, when a number of students have made the same answer and the answer is not among the standard answers, the answer is filled back to the original question and submitted as a true or false question to the corresponding teacher to be judged, and the answer approved by the teacher is automatically added to a question bank. Accordingly, active knowledge updating of the platform is realized, thereby raising the efficiency of database maintenance and reducing data updating cost.

Description

technical field [0001] The invention relates to an online learning system, in particular to an online learning system with a self-correcting function. Background technique [0002] With the development of technology, online teaching technology has gradually matured, and corresponding platforms in the market have also designed various learning systems in a targeted manner. For example, the invention patent "Personalized Online Learning System" with patent number 201480068310. Personalized online learning system, in more detail, the related personalized online learning system automatically provides learning questions to the learners' respective terminals under the condition of online connection by utilizing their respective terminals, And let each learner use the terminal to answer the learning questions, accept each learner's answer input through the terminal to evaluate the students' grades, and additionally provide time information required to answer each question, answer i...
