Method and system for constructing segmented and cumulative exercise database based on classmate participation in spoc platform

Abstract

The invention provides a stage-accumulation-type exercise database construction method and system based on student participation in an SPOC platform. The exercise database construction process is divided into an exercise input stage, an exercise analysis input stage, an answer data dynamic interaction stage and an exercise intelligent pushing stage. Each stage can enable the exercise database to be updated dynamically. According to the constructed database, a server can execute a preset exercise pushing strategy based on request signals sent by student terminals, and feeds back the exercise data targeted by the strategy to the corresponding student terminals. The exercise database construction method can construct the exercise database dynamically in a stage-accumulation manner and a manner that the metabolism of the exercise database is manually intervened; and meanwhile, exercise intelligent pushing under different strategies is realized. The method can update and adjust the exercise database dynamically in real time according to the demands of users, thereby greatly optimizing interaction efficiency of the data in the SPOC platform, preventing mass data redundancy and improving user experience.

Description

technical field [0001] The invention belongs to the field of data interaction of mobile online teaching, and in particular relates to a method and system for constructing a segmented and cumulative exercise database based on the participation of classmates in an SPOC platform. Background technique [0002] SPOC is the abbreviation of Small Private Online Course (Small Private Online Course). It is an invention of Professor Armando Fox of the University of Berkeley in the United States. Usually, the number of students in SPOC is between a dozen to hundreds, not thousands. Professor Fox believes that if MOOC resources are used as a supplement rather than a substitute for school classroom teaching, it will enhance the value of teachers in teaching, promote students' positive thinking, help students master what they have learned, and maintain interest in learning. Note that the SPOC model mentioned by Professor Fox here is the same as the previous blended teaching model, except ...

AI Technical Summary

Problems solved by technology

[0005] However, in the current SPOC platform, the exercise database as the basic data is usually uploaded by the platform maintainers or teachers based on the information they have. The uploading of the exercise database is complicated and error-prone.

In addition, the maintenance and update of the exercise database is completely dependent on the operation of the management personnel, and it is impossible to dynamically update and adjust the exercise database according to user needs. The data interaction efficiency in the SPOC platform is low, and the user experience is poor.

Furthermore, its push strategy to user terminals is basically fixed or there are only a few modes to choose from, which cannot be adjusted according to the user's own habits and needs
