Design And Implementation Of Higher Vocational Colleges Of Online Course-selecting System

In recent years, with the rapid development of higher vocational education and theincreased number of students, universities have reform teaching system, implement ofcredit system, carry out quality education and individual education, pay attention to thecultivation of the students’ innovative spirit and practice ability. In order to guaranteethe education quality, and effective use of the software and hardware of the schoolresources, must provide a intelligent, flexible and systematic college courses system.The common elective course system mainly exist in the following three problems: tomeet the requirements of the distributed network, operation is too complicated andeducational administration management system of poor flexibility extensibility.This thesis mainly through the analysis of the relevant elective course systemonline technical background, using the object-oriented thought and method, analysis,design, implement a can of maintenance, can facilitate integration online courses system,to meet many kinds of teaching administration mode needs.This system is based on three layers of B/S application system structure, inMicrosoft.net environment, using Visual Studio2005powerful integrated developmentplatform, with asp.net and ado.net technology，developed a elective course systemonline which is suitable for the development of the higher vocational college, thebackend database used SQL Server2005to store data. In the demand analysis of thesystem, the first, made the general goal orientation for the system, put forward tofunctional and non-functional system requirements, then use UML to implement thedemand analysis modeling and the design of database concept structure. In systemdevelopment and implementation, according to the actual needs, completed the designof relation model, database in details and specific function code. Finally, choosed usecases to test for the system and put forward the further prospect.Finally, in the online courses system of higher vocational colleges which werealized, divided into management three function module:system management, teachersand students management of choosing courses, realized the course in timely andaccurate information release, teachers, students begin to declare, elective curriculumcourse, teachers and classrooms equipped, and the formation of teachers and studentswith schedule with the main function of the schedule based on real-time online chat tooluse can realize real-time communication between teachers and students, the students can realize to interested in the courses of the audition and experience of the function,and can in the study of teaching the most out after reasonable evaluation, so as to betterunderstand the class course, solve students blindly electing courses or passive course ofpresent situation, and strive to give students a more humanistic elective course system,reflect the information age of personalized management university course, help onlinecourses system improvement.Using the research results based on the system in higher vocational colleges, onone hand, college students can fully enjoy value-added services through the electivecourse system when choosing courses and enhance learning initiation, on the other hand,school can reduce a large investment in human resources during selecting the course,and improve the present situation of the heavy burden in the school educationaladministration management system.
