The main points are that the application research on the combination of modern educational technology and specific curriculum content is not deep enough in terms of the content that needs special attention in the development of education and teaching. Then it analyzes the disadvantages of traditional teaching and the superiority of modern educational technology applied in teaching, affirms the importance of modern educational technology, traditional teaching and modern educational technology should complement each other and integrate each other. Finally, some suggestions are put forward on the application of modern education technology in classroom teaching, focusing on the details of teaching work, paying attention to comparative analysis, practice, effectiveness, research refinement, the data of teaching effect, school-enterprise cooperation and curriculum digitization etc. Any new educational technology is only a teaching tool and auxiliary means, which cannot completely replace traditional teaching forms, let alone be implemented for the sake of implementation. The importance and necessity of modern educational technology are built on the basis of better serving students.
