Research And Implementation Of Teaching Process Control System Based On Workflow Engine

How to objectively evaluate the university student learning process has always been one of the key research topics in the general education of higher education institutions.If the assessment of students' achievement of the goal is only through the assessment of stage or homework,it is not objective,usually under the circumstances.The merits of students' academic performance are not detected by one examination or test.Only through the control of the learning process can it provide an important guarantee for the objective evaluation of students' achievement of learning objectives.With the rapid development of modern information technology,teaching process control is achieved through modern information technology to provide a new solution for the objective evaluation of students' learning process in universities.This thesis is supported by the Activiti open source workflow engine.It uses process control theory as a guide to control the teaching process through three aspects: first control,execution control and feedback control to achieve the effect of process control;and through the open source workflow.The prototype system of the engine's teaching process control verifies the effectiveness of this control method.The main work of this paper is as follows:(1)In-depth analysis and research on the current teaching process in colleges and universities,and in detail exploring the factors that affect the objective evaluation of students' learning process,and applying process control ideas to the teaching process in order to achieve the degree of achievement of student learning objectives.Conduct an objective evaluation.(2)Conduct a detailed analysis of the problem domain and analyze the various activities that students evaluate in the teaching process.The use of Activiti open source workflow engine technology to complete the modeling of the teaching process,a three-level evaluation model for the student learning process,in order to ensure theobjectivity of student learning process evaluation and the independence of student work,the use of improved SimHash algorithm for student work Recheck processing.(3)From the analysis of requirements,the main functions of the system are completed.Based on the application characteristics of the domain,the overall architecture of the system is completed based on the workflow engine.Secondly,each functional module of the teaching process control system is designed in detail.Each functional module has completed the analysis and design of the database table,and finally completed the integration of the teaching process control system and workflow technology and the design of the Activiti core flow chart.(4)Based on the detailed design of the system,the prototype system was implemented,the deployment of the Activiti core flowchart and the implementation of key technologies were completed,and the system was demonstrated.
