An Empirical Study Of Online Learning Intervention From The Perspective Of Learning Analytics

With the development of information technology,online learning is becoming a new kind of study way,which has also become an important study form of the current higher education.But in the process of education informationization,online learning has not achieved educators to the desired effect.The influencing factors of online learning is more complex,lacking of learning guide and precise intervention is one of the important aspects among them.From the perspective of learning analytics,this study is aimed to find out the method and process of online learning intervention based on the design and application of online learning intervention model,in order to improve the study effect,avoid the risk of learning and promote academic success.From the view of learning analytics,in-depth analysis of this research expounds the connotation of learning intervention,classification,characteristics,model and practical application.Among them,RTI model is the prototype of learning intervention model,and learning intervention model is divided into three levels by RTI model.The first level is geared to all learners,which belongs to the basic study intervention.The second layer is for students who have some learning risks,which belongs to the group intervention.The third layer is based on the assessment of risk point learners individual,which belongs to the individual intervention.On this basis,this study construct the model of online learning intervention mainly includes five elements:Screening;Monitoring;Multi-level Intervening;Decision-making and Analysing.The multi-level intervening is divided into group intervention,team intervention and individual intervention.This model is a recycled intervention model,which uses of learning analysis technology collecting,analyzing and selecting online learning behavior data,to predict the learners who may be have risks of study,and in a timely manner to provide continuous learning evaluation and appropriate intervention.On the basis of constructing online learning intervention model,this study uses the model in online learning,to carry out the preliminary experimental study;according to the result of preliminary experiment,we summarize the shortcomings of the pre-experiment process and carry out formal experiments.Through the learning process and learning results for data analysis and investigation interview,the study find that online learning intervention model application effect is good,the subjects of study findings with the model prediction conclusions not only are roughly consistent,but also adaptive to learners for intervention strategies and measures,effectively evading the risk study.
