Embodiment 1

[0055] Embodiment 1, a kind of calculation method of student's knowledge point grasping probability, calculation formula is P(θ)=1 / (1+e^(b-θ)), wherein, θ represents the ability parameter of assessing students, b represents each The difficulty coefficient of a topic, e is a constant 2.71828;

[0056] Among them, for this knowledge point, b adopts the standard difficulty coefficient, which refers to the unified difficulty coefficient standard determined through quantitative and qualitative research methods for all platform students.

[0057] According to the accumulated practice data of a large number of students on the whole platform, combined with the correct rate of each question (the correct rate of each question adopts the average correct rate of all parts of the country (counties) to reduce the impact of differences in teaching levels in various regions of the country, and then ensure The standard difficulty coefficient is universal and reasonable for all parts of the cou...

Embodiment 2

[0064] Embodiment 2, on the basis of Embodiment 1, calculate the P(θ) of the 1PL model combined with the item response principle (IRT) and the R value of the forgetting curve, and diagnose the probability of mastering the knowledge points of the platform students.

[0065] A method for diagnosing online learning knowledge points, comprising the steps of:

[0066] Step 1: Evaluate the probability that students have mastered the knowledge point based on the item response principle, which is the same as that in Embodiment 1, and will not be repeated here.

[0067] Step 2, evaluate the student's degree of memory for the knowledge point, the calculation formula is R=e^(-t / s), wherein, t is the time interval with days as the basic unit, s is the memory strength, and e is the constant 2.71828;

[0068] The calculation method of s is: the initial s=1 of each knowledge point, and the minimum value of s is 1, if the practice answer is correct, then the direct and indirect knowledge poin...

Abstract

The invention discloses a parent terminal system based on a cloud teaching platform, which is in communication connection with a cloud teaching platform database and a student terminal. The parent terminal system based on the cloud teaching platform comprises an intelligent question organizing module, an online live broadcast module, and a learning trajectory recording module, wherein the intelligent question organizing module evaluates a knowledge point mastering possibility of the student according to an item response principle and a forgetting curve and calls needed exercise questions in an exercise question library of the cloud teaching platform database and sends the needed exercise questions to the student terminal; the online live broadcast module is used for live broadcasting a real-time picture of the student terminal on the parent terminal; and the learning trajectory recording module is used for recording the online learning condition of the student. According to the technical scheme adopted by the invention, with the help of massive data stored in the cloud teaching platform database, the needed exercise questions are called from the question library of the cloud teaching platform database and sent to the student terminal, personalized questions for the student can be realized, and through the online live broadcast module and the learning trajectory recording module, the past and current online learning conditions of the student are mastered, and interaction with the student is further realized.

Description

technical field [0001] The invention relates to an online teaching platform. Background technique [0002] With the development of the network, students' learning is closely linked with the network. Many schools and educational institutions have designed online teaching platforms, but traditional online teaching platforms focus on the development of students, and parents cannot keep abreast of students' online learning. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a parent-end system based on the cloud teaching platform, which is convenient for timely grasping the online learning situation of the students, and can realize the interaction with the students. [0004] In order to solve the above-mentioned technical problems, the present invention adopts the following technical scheme: the parent-end system based on the cloud teaching platform is connected to the cloud teaching platform database and the student t...
