| The requirement of innovational and practical ability has been put forward for the talent in the 21 st century.To meet the requirements of talent,state and society encourage people to be innovated and practiced in knowledge economy age.How to seize the opportunity to develop more innovative talents has become a major topic for colleges and universities to explore.One of the main research methods studying in teaching experiment is using the Web technology.This thesis is based on teaching research project named "The Research of Experiment Teaching Mode for Innovative Practice Ability and the Practice of Web Platform ",using Web development technology to build innovative experimental Web platform and exploring the teaching methods in training creative ability of students.The work in this paper mainly include: the background information,objectives and significance of this thesis,the basic knowledge of Petri net and related technologies used in the experimental Web platform are generally introduced.Next,it analyzes the demand of innovative experimental Web platform,divides function of the platform and builds Protocol model by using Petri nets;then,this paper introduces the implementation details of the experimental discussion groups which is based on WebSocket technology,Finally,it shows the whole experimental result,introduces the Discuz BBS function which is integrated into the innovative experiments Web platform developed by python,concludes this thesis and gives the outlook for further study.Innovative part of this paper is mainly reflected in several ways:1)Based on Petri net model to achieve the functions of process control in resource-limited settings.Through analysis of the process of basic experiments,improving experiment,and innovative experiment,using capacity functions of place and changing weight function of transition in place/transition Petri net to allocate resources and to solve the problem of a shortage of resources.2)The realization of the instant communication module based on B/S structure and seamlessly integrated into Liger UI framework in the Web platform.After comparing a variety of real-time communication methods,finally we choice WebSocket which has advantages in aspect of stability,concurrency and save flow to design and achieve the function of experimental group discussion,combined the WebSocket module with Liger UI framework to realize the function of the real-time interaction between teachers and students.3)Based on aggregation function of the Discuz community.By introducing Discuz BBS into innovative experimental Web platform,teachers and students have more abundant resources sharing platform and interactive communication channels. |
