Detailed data collection of online education platform

Online education platform is a software system that supports online teaching activities. Entering the information age of 2 1 century, modern distance education marked by network education stands out in the information age of the century. Network education is a new form of education in which modern information technology is applied to educational production.

The key to the implementation of online education is to create a network environment that can promote learners' active learning, and learners' learning activities in the network teaching environment cannot be separated from the online education platform.

Overview of online education platform: software system division of online teaching and learning activities: on-demand, interactive and social teaching platform features: combination of real-time interaction and recording on-demand, teaching mode, characteristics, development history, online education, admission requirements, learning content, examination subjects, academic recognition, platform composition, key technologies, construction methods, and generalized online teaching platform including hardware facilities and support for online teaching. In a narrow sense, the network teaching support platform refers to the software system that provides comprehensive support services for network teaching based on the Internet. A complete online teaching support platform should be composed of three systems: online course development system, online teaching support system and online teaching management system, which respectively complete the functions of online course development, online teaching implementation and online teaching management. From a macro perspective, the status of distance education platform largely reflects the development level of modern distance education in a country or region. As far as a distance education entity is concerned, the distance education platform is the basic activity space of distance education teaching and management, which is related to the quality and efficiency of teaching and management. On the basis of the original teaching system, the teaching mode network teaching platform integrates the main subsystems needed for network teaching, and constructs a relatively complete network teaching support environment, from the comprehensive support for the teaching process (courseware production and release, teaching organization, teaching interaction, learning support and teaching evaluation) to the organization and management of teaching (management of users and courses), and then to the integration with the network teaching resource database and its management system. With the development of internet technology, database technology and multimedia technology, the demand for learners' participation is increasing, and the understanding of distance learning under the network environment is getting deeper and deeper. Network teaching platform can be divided into three generations:

The first generation: on-demand teaching platform

In the early stage of online education development, the on-demand teaching platform mainly realized the rapid transmission of teaching resources. Students can request audio and video courseware, consult electronic lesson plans and complete online homework anytime and anywhere. Its main features are courseware-centered, online electronic display of educational resources and emphasis on management.

The Second Generation: Interactive Teaching Platform

Instant messaging technology is widely used to provide online and offline teaching support services. The teaching platform integrates video conferencing system, virtual classroom system, chat tools, BSS discussion system and internal mail system, providing students with services such as learning navigation, online and offline courses, answering questions and counseling, discussion and online self-test, and improving the level of teacher-student interaction and the learning effect of students. Its main characteristics are student-centered, strengthening the interactive function of teaching platform, and emphasizing the timely and effective service for students.

The Third Generation: Socialized Teaching Platform

With the rapid development of Internet technology, the strengthening of globalization trend and the proposal of socialization of learning, learners build their own learning networks, including resource networks and partner networks, through social software such as intelligent search engines, RSS aggregation, blogs (using comments, news and citation announcements) and Wiki, and are in a state of continuous improvement and optimization. Its main characteristics are socialization, the sharing and creation of collective wisdom, and the emphasis on socialization of learning. Features 1, highly simulating virtual classroom, combining real-time interaction with recording on demand; Broadcast and record immediately, record synchronously at the beginning of training, and can be on demand immediately after training, which is convenient to adapt to various training scenarios. Virtual classroom system. 2. Taking the training content as the center, it is convenient for customers to choose according to their own needs, which is conducive to integrating high-quality curriculum resources and forming a curriculum resource center. 3. Provide real-time or non-real-time interaction between training teachers and students in various ways to ensure the training effect to the maximum extent. 4. Powerful content management system, batch course authorization, control of students' learning times, time monitoring and tracking of learning behavior provide great convenience for management. 5. Good expansibility and seamless connection with the company website and other training and teaching products; Managers can set the color, font size and layout of the management platform. 6. web-based access mode, which does not need to download any client software and can be accessed directly through the browser, is simple and easy to use. 7. The data adopts SSL encryption mechanism, which makes the training content and data transmission safe and reliable. 8. The network bandwidth adaptive layered multicast technology designed according to China's network conditions is convenient for training in different regions and under various network conditions, and will not cause network congestion. 9. Support three mainstream types of online training: autonomous, guided and discussion. Since the pilot work of online education was carried out, great achievements have been made in the management mechanism, teaching mode, teaching management mode, talent training mode and resource construction of online education, and online education has become an important part of higher education in China. With the development of information technology and the progress of social economy and culture, online education will play an increasingly important role in building a lifelong education system and will also become an important means to create a learning society. Network Education Platform With the development of the Internet, more and more teachers put their own curriculum framework, lecture notes and reading lists on the Internet for students to browse, and use communication tools such as e-mail to communicate with students. Since then, the demand for online teaching has been increasing, and some colleges and companies have begun to develop professional online teaching application systems, mainly to help schools develop teaching resources. Later, the function was further improved to support the management of online teaching activities. Generally speaking, these online education platforms are all around the development and management of resources, and the development of online education platforms has gone through four stages.

The first stage: Content Management System (CMS). In the early days of the development of network technology, some universities, famous companies and some training institutions began to purposefully develop professional online teaching resource banks to store and manage teaching resources, thus saving costs, enabling learners to choose the provided network resources for autonomous learning and broadening the channels of knowledge dissemination. However, the function is limited to resource management, lacking relevant standards, inconsistent resource formats and low level of resource enjoyment.

The second stage: Learning Management System (LMS). Originally from the education and training automation management system, it generally provides functional modules such as online registration of learners, list management of teaching resources, user information management, data recording and statistics of learning process, but it cannot realize the function of generating learning content.

The third stage: Learning Content Management System (LCMS). In order to facilitate teachers and course resource experts who have no technical foundation to design, generate, publish, manage and maintain network courseware, and facilitate teaching staff to track and count students' learning process, LCMS system is designed and developed. LCMS makes it possible to share learning content and interact with teaching.

The fourth stage: network-based teaching platform. For example, on the basis of the original teaching system, the online education platform of university of international business and economics Distance Education College integrates the main subsystems needed for online teaching, from comprehensive support to the teaching process (courseware making and publishing, teaching organization, teaching interaction, learning support and teaching evaluation), to the organization and management of teaching (management of users and courses), and then to the integration with online teaching resource database and its management system, thus constructing a relatively complete online teaching support environment. About Network Education Network education is a way of education based on computer network. In educational activities, students use the interactive function of computers to communicate with teachers and other students in local networks (such as campus networks). If educational resources can't meet the requirements, they can look for more resources or information on the Internet. There are great differences between online education and traditional classroom education, and the advanced educational concept of online education shows its strong vitality. Admission notice Under the requirements of the relevant policies of the Ministry of Education, distance education is an independent enrollment and examination for colleges and universities, and colleges and universities will arrange entrance examinations according to their own training requirements and teaching conditions. But this kind of exam is a level exam, not a merit-based exam. It is mainly to understand students' basic knowledge and learning ability, so as to ensure that students can adapt to the requirements of their majors after entering school, and also to understand students' learning ability with the help of the Internet and multimedia, so as to help students learn in a targeted manner. Most schools adopt the examination strategy of "lenient entry and strict exit". As long as they meet the basic learning conditions, it won't be too difficult to enter school. In addition, if you meet the relevant regulations, you can also enter the school without examination. Online college entrance examination subjects? College: Chinese, Mathematics, English; University: College Chinese, English, Politics. The documents and certificates required for admission are lost. How to apply for registration? If the graduation certificate is lost, you can apply to the Academic Affairs Office of the original graduation school for a nationally printed graduation certificate.

You can also go to the Higher Education Employment Guidance Center of the local Provincial Department of Education to handle the Inquiry Report on Higher Education Qualifications.

If other documents/certificates are lost, you can go to the original issuing unit to reissue the relevant documents/certificates, or the original issuing unit will issue certificates.

What academic qualifications and admission qualifications do students need? Network education requires students to have strong self-control and autonomy, and can plan and arrange their own study; Teach by famous teachers, and enjoy the high-quality teaching resources of famous schools, which is suitable for students with "famous school complex". Online colleges generally have off-campus learning centers all over the country, and students can sign up for study nearby. Because you can study in your spare time, it is very suitable for improving your classmates while working. Junior high schools and undergraduate courses must have graduation certificates from ordinary high schools, vocational high schools, secondary specialized schools and vocational and technical schools or equivalent certificates; The starting point of junior college undergraduate course must have a junior college diploma or above in national education series. At present, online teaching information provided by distance education mainly includes teaching organization and management information, course information, teaching trends, counseling information and other educational information. 1. Teaching organization and management information includes teaching plan, professional teaching implementation plan, course teaching design plan, course introduction, matters needing attention in various teaching processes and announcements, etc. It is mainly used for the overall guidance, teaching organization and management arrangement of the teaching process. 2. Course information and teaching dynamic guidance information refer to targeted guidance information provided to students in a timely manner according to the requirements of teaching progress, including explanations of key and difficult points in each chapter, synchronous homework, test questions and analysis. 3. Other educational information also includes class activities, notices of online school activities, and dynamic introduction of students' study and life. Examination subject network education is a new concept after modern information technology is applied to education, that is, education is carried out by using network technology and environment, and relevant universities carry out academic education and non-academic education through modern communication network. For students who meet the requirements of undergraduate and junior college graduation, the school will issue higher education diplomas in accordance with relevant state regulations, and the state will recognize the diplomas after electronic registration. So what subjects do you need to take in online education? Online education exams are divided into two types: college entrance examination and senior high school entrance examination. In addition to the corresponding enrollment outline, there is no uniform regulation on the test set of teaching materials and supplementary books. When choosing counseling books and problem sets, it depends on whether the publishing organization is a legal person and whether the writing team has a formal name. It is best for publishing houses and publishing units to choose formal units. When buying books, you should go to a big bookstore or a district/county online education office to buy online educational counseling materials to prevent piracy, counterfeiting and shoddy work from harming others and yourself. You can't be greedy and cheap when choosing online education guidance books. The subjects of online education examination in Shenzhen are: high school starting point: Chinese, mathematics, foreign languages, historical geography, physical chemistry. Starting point of junior college (upgraded from junior college): basic courses of politics, foreign languages and junior college. The subjects of the online education examination (the answer sheet is not divided into examination papers) are: medical integration (specialist). Since 1999, the Ministry of Education has approved 67 ordinary colleges and universities and China Central Radio and TV University to carry out modern distance education pilot work, allowing the above 68 pilot colleges and universities to carry out academic education and non-academic education through modern communication networks on the basis of on-campus online teaching. Students who meet the requirements of undergraduate and junior college graduation shall be awarded higher education diplomas by the school in accordance with the relevant provisions of the state. After the electronic registration of graduation certificate, the state will recognize it. According to the relevant archives of the Ministry of Education, colleges and universities that offer distance education with the approval of the Ministry of Education have the right to run schools independently, make plans independently, enroll students independently, take entrance exams independently, and decide what diplomas to award independently. All majors offered can be awarded degrees. These diplomas and degrees are officially recognized by the state and participate in the online "electronic certification registration" of national academic diplomas. On the website of the Ministry of Education, there is also the original text of "Online Education College should implement the credit system". The validity period of credits and the length of study shall be determined by the school. For students who meet the requirements of undergraduate and junior college graduation, the school will decide what form of graduation certificate to issue after careful study; The academic certificate is printed by the school itself and the electronic registration system is implemented. The registration method shall be stipulated separately. After electronic registration, the state recognizes it. "The graduation certificate shows that you have completed the courses specified in the teaching plan, completed the graduation thesis or graduation design and passed the examination. Beijing Institute of Technology will issue diplomas. The graduation certificate is marked with the words "online education". The degree is awarded to qualified undergraduate graduates majoring in business administration, human resource management, project management, marketing, information management and information systems, and a bachelor's degree in management can be awarded; Undergraduate graduates majoring in accounting can be awarded a bachelor's degree in economics; Bachelor of law degree can be awarded to graduates majoring in law; Computer science and technology, mechanical and electronic engineering, and automobile service engineering can be awarded a bachelor's degree in engineering. For example, the online education platform of university of international business and economics Distance Education College mainly includes the following subsystems: teachers' real-time teaching system, students' autonomous learning system and evaluation feedback system. The main purpose of teachers' real-time teaching system is to increase the sense of presence and improve the learning effect. At present, online education institutions in China mainly adopt advanced two-way, real-time and interactive systems. The main transmission platform is communication network, and the video conference system based on H320 protocol is the main terminal equipment, and remote multimedia classrooms are established in various places to organize learning. Students' autonomous learning system is one of the advantages of online education. Teachers' real-time teaching requires students to attend at a certain time. Due to time constraints, the learning style is not very flexible. Many educational institutions provide students with autonomous learning systems, including network-based multimedia courseware and database-supported information retrieval systems. These systems are carefully designed and made by teachers or specialized personnel to meet the reference and supplementary needs of students in their studies. The separation, evaluation and feedback system of teachers and students in online education is produced in order to know the students' learning situation in time and solve the confusion in the learning process. The communication between teachers and students is mainly realized by synchronous tools, such as chat system and telephone, and asynchronous tools, such as email and BBS. Key technologies According to the characteristics of the hardware supporting environment and system composition of online education in China, we can summarize the main technologies involved in the construction of learning environment of online education platform as follows:

(1) Audio and video compression coding technology. Audio and video compression adopts different compression methods according to different network bandwidths, which can provide students with high-quality audio-visual materials, stimulate students' interest in learning, reduce the download time of network resources and ensure the authenticity of real-time teaching. (2) Network technology. China has built three major network systems represented by telecommunication network, optical fiber ground network, satellite skynet and computer internet. Because each system has its own advantages and disadvantages, in order to get better education quality, the three major networks often learn from each other and use them together. (3) Access technology. Access technology focuses on how learners connect with online education system to obtain educational resources. Because online learning course resources usually have a large amount of data, the access bandwidth directly affects the learning effect, and the network cost in China is relatively high, so how to improve the access speed of learners in this case has a great influence on whether online education can achieve the expected effect. (4) Video conference technology. Video conference is a communication service that mainly transmits audio and video. It meets the requirements of real-time communication between teachers and students in online education, and it is a point-to-point or point-to-multipoint interaction mode. (5) Information publishing technology based on IP. IP online publishing technology is one of the most widely used technologies in online education system. It is combined with the video conference system to complement each other and complete the release of teaching resources. There are many IP-based information publishing technologies, and Web technology, broadcast multicast technology and streaming media technology are mainly used in China.

There are also database technology and multimedia courseware making technology, which will not be introduced here. From the way of online education, it can be seen that the online education platform must have several major sections, including teaching resource database, online classroom design and release, after-school homework and examination, and instant and delayed discussion education resource database, which, as its name implies, is the place to store educational resources. It includes all kinds of educational materials, such as text, multimedia video, pictures, flash and so on. According to departments, majors and disciplines, it is convenient to use. According to the changes of the times, platform administrators and teachers constantly sort out, make and borrow educational resources to fill in, so as to ensure the timeliness and accuracy of resources. Students can also upload and share their own unique resources. For the interactive part of each subject, it is suggested that interactive teachers make materials together to make the content of educational materials richer and more coherent. Colleges and universities with large scale or need more information can consider building a sub-resource database to store the information of their own departments separately. When uploading resources, you can set options such as resource openness, which needs to be reviewed by the platform administrator to ensure the quality of resources. There are a variety of resource retrieval modes in the resource library, which has its own internal resource retrieval and resources are also linked to the one-stop retrieval of external platforms. The storage mode of educational resource database is generally classified by discipline, and its simple layout is as shown in the figure: online classroom online classroom is the educational discipline of online education platform. Faced with the massive information in the resource database, students will be blind in autonomous learning, so teachers need to clarify their learning ideas for students through online classes. Rio Tinto Technology's independent website building system tailored for teachers allows teachers to make their own decisions in their own classrooms, and all styles and formats are freely chosen by themselves. The steps of making online classrooms: random layout of online classrooms: The examination system needs to carry out necessary examinations in order to check the learning quality, and the E-power online examination system provides a platform for online examinations. E-power online examination system is a patented product that Rio Tinto applied for the national patent number, and it is a systematic product developed in view of the current situation that online education in colleges and universities needs to be popularized urgently. Compared with other similar products, E-power online examination system has the following characteristics: 1, powerful online monitoring system. Record the students' study materials and the start time of browsing in the examination system. Teachers can learn about students' learning by reading their learning records, so as to better understand their own students. 2. Powerful analysis function. Test papers can be divided into manual test papers and automatic intelligent test papers. Intelligent test papers can control the difficulty of test papers (choose the difficulty when entering the question bank). After the exam, the system can automatically grade the objective questions and analyze the overall test paper, so that teachers can know which part of their students' knowledge is lacking and need to strengthen their study. 3. Strong compatibility. Whether it is exams, students' online learning or homework, whether it is video, audio, flash, PPT, Word, etc., it has strong compatibility with the format and expression of topics and materials. E-force online examination system function: E-force online examination system layout: discussion group tools include instant discussion and delayed discussion. Instant discussion is similar to QQ and other real-time communication tools, which can support multi-person communication; Delayed discussion is similar to delayed communication tools such as blog and Weibo, and can also support multi-person communication.
