Design And Implementation Of Interface And Platform For Learning Behavior Data Sharing

Since the "Internet+Education" evolves,various types of online learning platform has emerged.In the process of online learning,a significant number of learning behaviour data has been generated,which facilitates the learning behaviour analysis technology.Despite the fact that the learning behaviour analysis stems from the acquisition of considerable number of learning behaviour data,it can be difficult to share these data through different platforms and sources.To be more specific,format standardisation,the data dispersion and the lack of data openness are likely to prevent the extensive application of learning behaviour data,impeding the sharing of learning behaviour data.According to the research of a model for learning behaviour data,this thesis designs and implements the learning behaviour data sharing interface and platform,and aims to aims to establish a feasible learning behavior data sharing solution.The main tasks are as follows:Firstly,based on the existing eLearning specifications such as xAPI,this thesis evaluated the essence of learning behaviour,analysed and quantified its components as well as established a standardised model for learning behaviour data.This model decomposes learning behavior into six elements:subject,action,object,result,context,time,and records semantic learning behavior data in a unified format.It solves the problem of format standardization in data sharing.And then,based on the learning behaviour data model and the use cases analysis upon the requirements of users,the interface and platform of learning behaviour data sharing are designed and implemented,provides data transmission interface services,data authorization services,and data storage services through data sharing API,platform portals,and background management functions.On the premise that the system uses an authentication mechanism to ensure data security,this system allows authorized users to transmit learning behavior data in a standard format through a RESTful specification data sharing interface,which reduces the threshold for users to upload and obtain data,and according to the characteristics of the data,selects a targeted storage solution toimprove the efficiency of data reading and writing.So this system finally solves the problem of data decentralization and data openness in data sharing.The learning behaviour data sharing interface and platform designed and implemented in this thesis provide an integrated solution for the record,transmission,and storage of online learning behaviour data.It also offers a new method for the data usage scheme of online education,contributing to the sharing of learning behaviour data and the development of education informatisation.
