The Design And Implementation Of Micro Lecture Online Learning System For Liaoning Jidian Polytechnic

With the continuous development of information technology and Internet technology,in the background of the construction of educational informationization in our country,micro lecture has become a hot topic in the field of education,and has been widely concerned by domestic and foreign scholars and teachers?At present,some of the micro platform,due to the development of the concept of design,and more are some of the events such as "China's micro network" platform,such a resource platform emphasizes the teacher's most exciting a micro lecture,there is no continuity of the curriculum,the lack of the necessary teaching aid resources,learning and teachers are difficult to communicate,and the contents of the school teacher education can not be synchronized,there is no perfect evaluation mechanism.Therefore,the design and development of the characteristics of Higher Vocational Education in the micro lecture resources platform,and promote the development of higher vocational education,the pace of the construction of information technology is of great significance.This thesis first analyzes the application characteristics of the development process and the application platform of the micro lecture in China and abroad,and summarizes the application scenarios of the existing mainstream micro lecture platform,and puts forward the detailed design scheme of the online learning system with the characteristics of Liaoning Jidian Polytechnic.The system uses.Net three layer structure system and based on B/S model development and have good reliability and scalability.The system is divided into five sub modules,respectively is the authentication module,micro lecture learning module,online test system module,online forum module analysis and resource center module.According to the software engineering idea and development process of the system is discussed according to four stages.Specifically:system demand analysis,the feasibility of the system is discussed,and to determine the system's functional requirements and non functional requirements;system design stage,take a top-down approach,the functions of the system were a full range of design,and then develop the design principle and structure of the database;in the implementation phase of the system,to the user operation process for the lead,discusses the process of the realization of the main function module of the system;in the system testing phase,according to the testing principle of the developed testing methods,steps and environment,and select test cases the test process was discussed in detail.
