Problems solved by technology

[0002] At present, the teaching platform is basically used to support the textbooks. It has a single function. Teachers need to prepare lessons before class. During the lesson preparation process, paper textbooks are often used for lesson preparation. The efficiency is low and it is easy to cause forgetting. With the development of the times With the advancement of science and technology, multimedia teaching devices such as computers and projectors have gradually replaced traditional teaching tools such as blackboards and chalks, and can improve the vividness and efficiency of teaching in the application of teaching, training and reporting. New computer classroom teaching devices The use of it has greatly changed the traditional teaching methods, facilitated educators, greatly reduced the labor intensity of teachers, and effectively improved teachers' teaching efficiency and students' learning efficiency and interest, and enhanced the relationship between teachers and students; but the existing The new type of computer classroom teaching device is still insufficient in specific use. At this stage, computers are also installed on the desk and a projector is installed above the blackboard. This is cumbersome to set up and connect separately, which brings trouble to the installation, and the general equipment does not The device can be moved, and the teaching sound is low, which is not conducive to teachers' lectures, and it is inconvenient to use. There is still no better solution at this stage
