Research On Data Service Design And Application Based On Hstar

The online learning platform has brought about changes in the education and teaching of colleges and universities.The teaching mode of colleges and universities has gradually changed from the traditional teaching style to the flipping classroom,and the teaching objectives have gradually changed from overall improvement to individualization.In the online teaching based on the online learning platform,the teacher can't supervise the learner's learning state in real time,and can't carry out targeted teaching.The learner has a strong self-learning ability and the learning risk is high.How to effectively solve the above problems has become a hot spot in the field of modern education.Through the research on the traditional teaching support platform,it is found that most of the platforms focus on business functions,and the data services are relatively weak.The platform supports the behavioral data in the learning process to be granular,and ignores the process characteristics of the learners.Pay attention to the analysis of the group and despise the analysis of the individual.Therefore,the traditional teaching support platform can no longer meet the teaching needs of teachers with increasing data awareness.In order to meet the needs of today's hybrid teaching,this paper proposes the design of data service based on Hstar platform.Users in this platform are not only producers of data,but also consumers of data services.The platform provides users with sound business functions and high-quality data services,enhances teachers' data awareness,and presents learners' learning processes in real time,facilitating teachers to carry out targeted teaching interventions.The research work of this paper is mainly as follows:Firstly,it analyzes the current situation of traditional teaching support platform in the process of continuous change of education and teaching,and expounds the research significance of data service based on Hstar platform.Secondly,a data-driven Hstar platform architecture is proposed.Four core user roles in the platform are introduced,and the platform is constructed in detail from two dimensions:business function and data service.Thirdly,the key technologies of the five data services,such as learning completion,learning behavior input,curriculum health,activity,and curriculum supervision,are elaborated.The learning behavior input measurement is established based on the platform teacher's curriculum evaluation standard.Table,course health metrics and curriculum improvement metrics.Finally,the implementation and application of data services based on the Hstar platform are described.Explain the data collection and processing process in the platform,present the data service effect of the core user role in the platform,help the teacher to make decisions,help the learners to check for missing gaps,and reduce the learner's learning risk.
