3。 Relationship between the Flipped Classroom and Education Informatization 

3。1 Development of Education Informatization文献综述

The interpretation of Educational Informatization is not only a theoretical research, but also an educational practice。 “Information” first appeared in some of the academic literature in the 1960s in Japan。 At that time “information” is mainly defined from the industrial point。 In the 1970s, Germany, the European Union and UNESCO and other international organizations have introduced a series of plans to promote the application and development of information technology in society。 These plans consider the information infrastructure as an important part。

In September 1993, the Clinton Administration formally proposed the construction of the National Information Infrastructure (NII), commonly known as the "Information Superhighway" program。 The core of the project is the development of a comprehensive Internet-centered Information Service system and the promotion of information technology, abbreviated as IT, in various fields of social applications。 Because of this, many developed and developing countries have introduced a series of national information infrastructure construction plan, which led to the global information。

The concept of Education Informatization was proposed in the 1990s with the construction of the information super highway。 In the US "information superhighway" program, the application of IT in Education was especially considered as an important way of the implementation of the 21st century education reform。 This measure of the United States has aroused a positive response from various countries in the world。 Many governments have formulated plans to promote the use of IT in education。

With the rapid spread of network technology, the relationship between the development of society and information technology have been closer since the late 1990s in China。 People increasingly concern about the impact of information technology on social development。 "Social Informatization" formulation began to appear。 Linking to the educational reform and development, “Education Informatization” formulation also began to appear。 Government documents have officially used the concept, "Education Informatization", and attached great importance to the work of Education Informatization。
