The "three links" are broadband network school-to-school communication, high-quality resources classroom communication and online learning space for everyone, and the "two platforms" are public service platforms for educational resources and education management.

In the front-end environment construction, the traditional blackboard is replaced by information teaching terminals such as "electronic double board", which is a "double track teaching" system based on Pevio's "double coding" theory. The front two digital display devices supported by the teaching software platform realize the "dual-track presentation" of classroom teaching content, and simultaneously display abstract content and image content through dual screens, which stimulates learners' left and right brains and promotes learners. Secondly, the digital transponder based on the Internet of Things and the information-based learning terminal based on the tablet computer, as students' terminal equipment, are fully connected with the "electronic double board" teaching terminal, which makes the efficient real-time interaction and accurate process evaluation in the classroom teaching process become a reality. Thirdly, the information terminal of group cooperative learning is equipped to provide conditions for group cooperative inquiry, and support group cooperative learning, problem-based teaching and independent cooperative inquiry in the classroom teaching process. Finally, comprehensively optimize the audio and video acquisition and transmission equipment in the classroom to provide support for real-time communication and remote interaction.
