Research And Implementation Of Teaching Process Control Platform Based On Data Visualization

With the rapid development of the society,the education in colleges and universities is also constantly improved and optimized,but how to objectively evaluate the learning status of students in the teaching process is still an important subject in modern education.If students' learning process is not tracked and analyzed,their learning status is only judged by their grades,however,it is not conducive to the optimal allocation of learning resources,the perfect allocation of teaching services and the improvement of learning efficiency in teaching activities.Aiming at the above problems,this thesis applies data visualization to the teaching management of colleges and universities,providing a new way for teaching process control.Interactive and visual methods are used to reflect the learning status of students,and trace data are collected in the teaching process based on the multi-dimensional index evaluation system,according to the role of the need to achieve teaching objectives,evaluation and other information visualization display and analysis,to provide effective support for teachers to improve the teaching process and to optimize the learning plan of students.The main contents of this thesis are as follows:(1)Research on teaching process modeling.This thesis analyzes the problems existing in the teaching process of colleges and universities in detail,such as the students' learning evaluation is not objective enough,the feedback of problems in teaching implementation is not timely,and part of the repetitive work in the teaching process takes up a lot of human costs.Studies the objective evaluation factors of school students in the teaching process,and proposes an improved teaching process control model by combining the process control with the teaching process.In order to ensure the normal execution of the teaching process,the process of teaching supervision mechanism is determined.Around the objective comprehensive evaluation of students' learning situation teaching process evaluation model is putforward.Process automation model design based on Activiti workflow engine and Drools rules engine.(2)Research on teaching process control visualization.According to the characteristics of teaching business in colleges and universities,domain roles are divided,and process visualization needs are analyzed according to the business needs of domain roles.Complete the processing and analysis of trace data in the teaching process to provide support for process visualization.Based on the process visualization requirements and d3.js visualization tools for the process control platform interaction design.(3)Design of visual teaching process control platform.Based on the analysis of platform requirements for problem domain,the platform architecture design and business process design are carried out.Combining with the domain model of teaching process,the static model,the use case realization,the functional module and the database design are completed.(4)Visual teaching process control platform prototype implementation.On the basis of the above design,the prototype of the platform was developed,and the key technologies and core function modules,such as process flow,data visualization and dynamic rule evaluation,were implemented,and the operation effect of the main functions of the platform was demonstrated.
