Informatization. In this era, information technology and education and teaching are deeply integrated. Digital campus construction and digital educational resource system have gradually become the standard of all subjects in basic education, and the way of teaching and learning has changed. Heuristic, interactive and inquiry-based teaching is more popular, and research-based, project-based and cooperative learning is more valued. Based on modern information technology, it is possible to accurately analyze the learning situation and teach and learn remotely, but what remains unchanged is tireless innovation and exploration, and teaching and learning learn from each other's strengths.
