Project Name: Teaching Station Teaching Academic Affairs Management System (Esteams) Project
Background and significance of research
Teaching Station Teaching Academic Management (Esteams) (hereinafter referred to as Esteams) is based on a certain university distance education platform, according to the teaching station (the Ministry of Education "is called" school teaching point "). The modern distance education platform system of a certain university is a national 863 key project, which has been put into use and continuously improved and improved during use. A certain university distance education platform is central server mode, and the entire system platform has only one data center, with users of the system administrator, the continuing education school administrator, teaching station administrator, teacher, and student. All characters are completed by logging in to a university distance education platform. This model has centralized management, centralized control, lowest deployment cost, easy to manage control, easy to maintain updates.
The increasingly important means of modern distance education is the network learning. A visiting platform is applied to the network in the traditional college, and gives full play to the advantages of the network, reflecting the modern distance education ", anyone, anywhere, At any time, start from any chapter, learn any content. But the current domestic basic network environment can not support real network education. In response to the functional status of a certain university distance education platform, we refer to the domestic and foreign distributed network education solutions, and propose a distributed terminal server system located in the teaching station, as an extension of a certain university, modern distance education platform, to achieve Distributed remote teaching, one real network study, two for development of several emergency enhanced modules in the platform, forming our teaching station teaching teaching management system.
The purpose of the teaching station teaching, teaching management system, relying on the actual needs of teaching station management, according to the specific needs custom management system, to finally achieve distributed network learning, facilitate students to learn, and provide convenience for students on the distance education platform.
Combined with a certain university's existing distance education platform, providing a complete set of network education solutions based on modern internet networks, establish a separate teaching and teaching management system for the teaching station to achieve distribution teaching to address network bandwidth. You can make students have a better network learning environment to serve the teaching and teaching of teaching stations.
The main content of our research is how to ensure the teaching quality of distance education by calculating the network to ensure the quality of teaching. Esteams is a serious analysis of the teaching process of distance education, in order to conduct problems in the teaching process of science in China, combined with the status quo and characteristics of modern distance education in the teaching process of international education. A set of operating platforms for modern distance education and network education.
EsteAms solves several practical problems of a certain university distance education platform:
1 Distributed storage of course courseware, to facilitate students' network learning: fully considering domestic network status, a certain university's network status and teaching station's current situation, to expand in an existing distance education platform of a certain university, according to The development phase and main characteristics of online higher education education. Solve the actual online learning problem of students.
2 The students of remote teaching are most busy. The announcements in the existing schools require students to take the initiative, and many students have failed to get online, thus missed its effect. We will change the notice, change the student's active view to passive reception, so that everyone saves a university Internet browsing announcement, notification time. Good real-time.
3 Diversity of notification: The original announcement and notice, only a form of pages, currently changed to a variety of forms such as page, Mail, SMS.
4 Tight combination with the original platform, except for the administrator of the teaching station, the authority of the student account judgment directly uses the username / password, security level, etc. of the original platform.
The management of all data from the students, the management of the student learning process, the management of the students, the management of the management of the school. Various floral names and statistics, teachers' management, teachers and students. 5 enhanced online communication and interactive environment
6 Addition of teachers to evaluate subsystems to make the teacher's teaching quality get feedback. To make students, students communicate with the teaching station teacher more convenient and fast.
7 The more resources, the higher the cost of its use, and for this situation, make the courseware cost student's small library, develop a user-local network resource search tool to achieve the search function of courseware resources.
Summary of research status at home and abroad
During the domestic company has studied companies, such as the "Linux-based distributed modern distance education platform" research on XX, is the electronic information industry development fund project in the Ministry of Information Industry. Using the master station terminal mode. The main function of the terminal is to complete the function of the students' network learning tracking management.
Research content and feasibility analysis
Because two students participate in the research work of "Linux-based distributed modern distance education platform", the industry has a certain degree of cognitive. Plus the other three students also engage in work related to software MIS research and development, should be able to complete the project research and development work on time.
