The Design And Implementation Of Online-learning System Based On ASP

With the rapid development of the Internet, the educational cause is gradually entering the age of network. Web as a new type of teaching media, you can visit anytime, anywhere, it is not only a good carrier content, but also provides many channels of communication, between teachers and students to facilitate the full exchange of views and discussions, which enhance the teaching of interactive And the overall quality of students as well as cognitive development are very important and effective. Online Education create a new teaching model, the development and use of this kind of study system which combines with the Internet is becoming more and more popular.To promote the reform of college teaching, effective management of student extra-curricular study, we developed the ASP-based online learning system, which aims to strengthen the School of Information building, the use of the Internet as the medium of the media, integrated curriculum resources for the management of computer courses so that students At the initiative to carry out extra-curricular learning, improve the quality of personnel training.First of all, this paper analyzed the background and significance of the system and put forward this issue to be used in research methods, introduced this issue to achieve the necessary technology and system design, and then the system needs analysis, design, detailed design and systems related to the achievement of key technology and other issues are discussed in detail.Online learning system using B/S model, the use of ASP, IIS, ACCESS Web site as a platform to run, needs analysis and database modeling using Microsoft Office Visio2003, front-end development platform IDE using DreamWeaver8, performance testing platform used LoadRunner8.0. ADO technical procedures used to visit with the transplant network as a tool for the database to ASP technology as a dynamic Web applications means that in order to achieve dynamic performance, but also the use of scripting language JavaScript.At present, according to the Guangdong Science and Technology Institute of Vocational Education of the status quo, we have put forward the e-learning system design, system administrator, teacher, student authorized by the three-tier approach, system mainly includes ten modules with the following functions:Examination / exercises library management module: College attached great importance to the examination / exercises library building, and to provide support for related conditions. For each course to create a number of library practice, each of the library contains multi-papers/multi-chapters, the subject can determine the type of questions, radio, check, a number of options, fill in the blank, Q & A And the title of the document submitted in the form of title. And set up the title of the degree of difficulty (1 - N up to a decimal), the effectiveness, and so on. examination / exercises library will also export to the WORD document.Practice information management module: operating normally do not use paper-based exercise books, and the use of online practice. First of all, a teacher from the operating arrangement (designated library practice, chapters, such as exercise classes), and then students online access to practice, marking the teacher, students can view the exercises of the standard answer.Examination management module: First of all papers generated by the teachers, set up examination of information; and then the set period of time, students can take part in an exam, or complete answer to the test of time, the A paper submitted to the system; automatic system to the objective title fight , The subjective questions from teachers on-line marking papers; students in the final examination results online.Learning materials management module: teachers can upload learning materials related to various courses, including electronic courseware, laboratory / practical training, curriculum presentation scripts, programs, and other reference materials. After teachers upload, students can download them through the Internet, and self-learning. The annex to upload has various types (such as word, access, powerpoint, flash, etc.) documents. Student attendance module: Teachers can query student attendance, and "generate attendance summary list."Teaching forum module: It is the discussion area between teacher and student; they can exchange ideas with each other. The student can ask question to the teacher, expert or other students, and they can publish their own opinions or explanations about the question; the teacher can setup some new problems to encourage students announce views here.Teaching classes module: school teachers to understand the situation, must know the college class of information (class size, headteacher, good record, bad records, etc.).Student information management module: school teachers to understand the situation, must know student's information (such as basic information, phone number, the other school-related changes, encouragement and punishments, acts as an office). It also can export "students information list " , "attendance, list " and "experimental registration form"Student Select Course module: Teachers can query courses selections to understand the situation.News management module: Teachers can also issue a press release, announcement.In the actual development of the system, test the safety of library design, how to smoke test paper title, control the operation of the examination period is the key. On the security front, the examination library documents using encryption and user password MD5 encryption and other methods; in the system using a standard test and based on random number of random algorithm title taken from questions, test paper; in the examination process, the shielding of the right mouse button, Control of the candidates can not use the ALT key and save the page file, and other operations, but also through the session object to allow users to refresh function does not affect the content of the papers.Online learning system is a few days ago, Guangdong Science and Technology Vocational College to run the system in operation, mainly the following characteristics:The function is pragmatic and can satisfy the different consumer's need such as students, teachers and administrators. On the resource structure, it can satisfy the student who has unlike structure of knowledge background and level.The operating interface is amicable and the interface of consumer and the administrator is divided, the design of usage function is pragmatic and convenient. The design embodies taking consumer's need as the centre, the guided characteristic is outstanding.The system has the characteristic of opening and expanding, it has realized the resource management opening design, and it provides the extensible interface to the realization and function of the system.The function of On-Line learning system has achieved the desired objective and supplements each other with the current situation and the teaching pattern. It has resolved some actual problems in existing educational model.
