1. Paper textbooks:

Also known as text teaching materials. The course teaching content carried by paper textbooks mainly includes basic teaching content, experimental content, learning guidance content and learning reference content.

2. Audio and video learning resources:

It mainly includes video and audio teaching materials. According to the different teaching contents and requirements, video teaching materials can be divided into two categories: systematic teaching and thematic teaching. Systematic teaching video teaching materials refer to video teaching materials that impart knowledge and skills comprehensively and systematically according to the knowledge system of course teaching content. Thematic video teaching materials refer to video teaching materials that help students deepen their understanding of what they have learned, master ideas and methods, and broaden their horizons in the application and development of disciplines by giving lectures, demonstrations, analysis or introduction on knowledge points or relatively independent teaching contents, such as course learning methods and requirements, teaching key or difficult contents, cases, experiments, and subject development contents. The content of thematic video teaching materials is not limited, and they can be made into separate films or inserted into systematic teaching video teaching materials. There are two main types of audio textbooks: direct recording and editing. Recording audio teaching materials directly in the recording studio or on site; Editorial audio textbooks are edited by music and synthetic recording materials.

3. Online courses:

It refers to the sum of the teaching contents and activities of a certain subject expressed through the network. The online course consists of two parts: the teaching content organized according to certain teaching objectives and teaching strategies and the supporting environment for online teaching. Among them, the network teaching support environment refers to the software tools, teaching resources and teaching activities implemented on the network teaching platform.

4. All-media digital teaching materials:

It refers to the use of ubiquitous computing and media integration technology, taking the core knowledge points of the course as the basic unit, integrating digital media such as pictures, words, sounds, images and paintings, and presenting the basic teaching content, main learning activities, exercises and evaluations of the course in a structured way, which is especially suitable for students to study and read in various environments (online and offline) by using mobile terminals. All-media is an integrated application of media form, media production and media communication, that is, to realize multimedia teaching content, diversification of publishing carriers and reuse and enjoyment of learning resources.

5. Courseware:

Refers to the computer-aided teaching software and supporting teaching materials that realize and support specific courses. According to the different application environment and development tools of courseware, it is mainly divided into CAI courseware (computer-aided teaching software) and IP courseware (streaming media courseware). CAI courseware is a computer software designed for course (specialty) teaching, which realizes the relatively complete teaching of one or several knowledge points. IP courseware refers to the network courseware which is synthesized by using streaming media technology and combining the function of web page making, and audio, video and lecture notes are transmitted synchronously on the network.

6. Online video teaching materials:

It refers to a kind of video learning resource that uses modern digital media technology to shoot and edit teaching content or knowledge information, and uses codec compression technology and streaming media technology to spread through the Internet and watch it on PC or mobile terminal. Its shooting follows the general law of audio-visual language creation, its teaching design conforms to the basic principles of distance open education, and it realizes more powerful interactive functions through network technology to meet the diverse learning needs of learners.

7. Learning resource package:

Learning resource package is a brand-new form of learning resources to adapt to mobile learning. The learning resource package contains a wealth of aid and examination resources, among which the core resources include paper textbooks, formative assessment manuals, final review guidance and all-media digital textbooks; Expanding resources include test question bank and PPT. All digital learning resources in the learning resource package are provided with technical support services by Open Cloud College.

Subject categories of National Open University

Relying on the existing foundation and advantages of RTVU, the National Open University makes full use of the nationwide school-running network, cooperates with universities, training institutions and relevant government departments, industries and enterprises, integrates high-quality educational resources, promotes the construction of disciplines and specialties, and builds a school specialty and certificate system that actively adapts to the needs of social and economic development, integrates academic education with non-academic education, complements professional education with certificate education, and has optimized structure and coordinated development. The major covers 9 disciplines of science, engineering, agriculture, medicine, literature, law, economics, management and teaching, and 19 vocational colleges. All undergraduate majors can be awarded degrees from the National Open University or cooperative universities.
