The core essence of education informatization 2.0 is innovation leading, starting a new journey in the intelligent era, striving to achieve the development goal of "three all, two highs and one big", and supporting and leading the modernization of education. An accurate understanding of the background and core connotation of education informatization 2.0 is of great guiding significance to the implementation of the action plan.

Teaching innovation in the smart classroom environment is a new topic of educational reform in the era of educational informationization 2.0. In the process of implementation, the following four problems should be solved.

First, teaching innovation is the key to the deep integration and innovation of information technology and classroom teaching. Teaching innovation must be carried out in an environment that can stimulate innovative consciousness and innovative thinking, and smart classroom is the technical and environmental support of teaching innovation. Therefore, it is urgent to design intelligent classrooms and innovative learning space technology application solutions.

The second is how to locate teachers and students with innovative teaching. Learning-centered, personalized teaching, learning-oriented teaching and teaching for learning are the concepts and principles that must be adhered to in the smart classroom structure and teaching innovation.

Thirdly, teaching innovation is the development process of intelligent teaching, which requires the change of teachers' concepts and ways of thinking. New teachers should gradually learn and master clear thinking, iterative thinking, cross-border thinking and innovative thinking, redefine education, teaching and learning, re-establish classroom teaching views, teachers' views, students' views, learning views and evaluation views, and finally implement them in the whole process of intelligent teaching.

Fourthly, teaching innovation ability is the core of teaching specialization and the key ability of excellent teachers. In the future, teachers should strengthen the consciousness and concept of teaching innovation, and take teaching innovation ability as the key index to consider excellent teachers.

Excellent teachers should make clear the new teaching concept, that is, no teaching model is permanent, no classroom is eternal, no student is not growing and developing, and no old capital can be eaten for life, thus forming a new classroom teaching concept of continuous teaching and innovation.
