The application of rollover classroom needs the assistance of information technology. Whether Teachers Produce Teaching Videos, upload videos, students watch and download videos, or the use of teaching resources, all need to be carried out under the network environment, we have to make sure that every student is able to watch instructional videos at home through an information-based device. At present, computers are relatively common in cities and households, and information equipment is not a thorny issue. However, due to the uneven economic development of various regions, the basic equipment of information technology in some areas of our country is not perfect, it's hard to flip a classroom. In addition, due to the pressure of the college entrance examination and the tight class hours, teachers have to give priority to the teaching effect, and students themselves are accustomed to the traditional teaching mode, so that teachers can not explore the new teaching model and learning. One teacher said that when he could not use the new teaching mode to combine the study of mathematical concepts, the cultivation of mathematical thinking and the cultivation of mathematical problem-solving ability, then he can only through the traditional teaching model first to develop students'ability to solve problems. However, this kind of teaching situation makes teachers unable to learn the information technology needed by the new teaching mode, and as teachers themselves grow up from the traditional teaching mode, the teachers themselves are not strong in the information technology, therefore, the information technology of teachers is deficient and it is difficult to change to the new teaching mode.
