The use of teaching media is a good tool for teacher-student interaction. In the future application, teaching media will become the mainstream, replacing blackboard chalk and oral English teaching. At present, teaching media are not sought after or given due attention, mainly because people notice that teaching media need to inspire students and students' initiative needs to be mobilized artificially. Moreover, at present, most teachers themselves are not familiar with the teaching media and cannot use it efficiently. We can't deny the role of teaching media in classroom teaching just because it is not widely used.

I think the use of teaching media mainly has the following significance:

First, it is the trend of the times, which will surely become the focus of future teaching, and its future is immeasurable;

Second, it is easier to teach, the teaching forms are diversified, and the students' cognitive ability is better improved and reflected;

Thirdly, interaction, the interaction effect between students, students and teachers, students and machines will far exceed the simple oral teaching;

Fourth, it can promote the development of teaching technology and promote economic transformation and reform.

Verb (short for verb) Media can provide specific experiences.

In a word, the application of media technology in education and teaching has promoted the development of educational ideas and teaching practice. But so far, it should be said that the application of media technology is not satisfactory, which should prompt us to reflect on the purpose and method of using media technology. It is not enough to use the media as a tool to convey information. We should deeply explore the important influence of media on learners' learning process, explore the important role of media in learners' cognitive construction, and guide the theories and methods of media application with contemporary learning theory. Constructivism learning theory reflects the latest achievements of contemporary learning theory research, and the research and practice of educational technology should be guided by constructivism and advocate constructivism learning. In constructivist learning, media technology can no longer only be used as a tool to provide information sources, but also play a role in promoting learners' cognitive construction, developing learners' cognitive ability and problem solving ability. Only as a cognitive construction technology, media technology can really affect the learning process and play its important role in education and teaching.
