Research On Design And Application Of Data-driven Blended Learning Intervention Model

With the development of multimedia technology and network technology,the scientific and high-quality development of education under the background of educational informatization has become the demand of educational reform.In the process of promoting the integration of online education and traditional education,teachers need to adapt to the blended teaching environment with the help of the new educational intervention mode of "data + experience driven".This study analyses the research status of learning intervention by combing the literature,and discusses the related researches and the characteristics of different interventions in various learning environment.In this study,we put forward learning intervention principles in blended-learning environment,according to the principles of traditional learning intervention.And we attend to build a data-driven blended learning intervention model,on the basis of the model of response to intervention,feedback theory and self-regulated learning theory,and in reference to the existing learning intervention model.The model includes five basic elements: students’ data,learners’ status analysis,the formulation of intervention strategies,the implementation of intervention strategies and the evaluation of intervention strategies effect.It takes student data as the core of this model and the learner’s status and classification will be analyzed by them.And then,educators have to develop targeted intervention strategy,and carry on the implementation and effect evaluation.The process of learning intervention is gradually improved and refined in this continuous cycle.In this study,we take students majoring in educational technology in a normal university as the research objects by quasi-experimental method.And the data-driven blended learning intervention model is applied to the course Learning Science and Technology course.Students’ learning status and performance will be compared before and after the intervention in three rounds of quasi-experimental research,respectively through questionnaire method,classroom observation method and interview method.According to the results of the experiment,we explore the application effect of the learning intervention model in the implementation of different learning intervention strategies and revise the model and then form the research conclusion.It is found that data-driven blended learning intervention model has a positive impact on students’ learning motivation,learning habits,learning attitudes and learning achievements to a certain extent.On the whole,the data-driven blended learning intervention model has achieved the expected application effect through teaching practice.
