The traditional teaching design has not fully adapted to the current teaching. There are many reasons. The key point is that with the development of society, great changes have taken place in many aspects, such as teaching objectives, curriculum design, teaching environment and media, and students' learning methods and ways. Especially today, with the rapid development of information, education and teaching must keep up with the changes of the times and make a thorough and comprehensive analysis of the learning situation. Study teaching activities from the perspectives of pedagogy, psychology, informatics and communication. To really understand, explore and practice your own teaching activities, so as to find out the best teaching methods and ways, so as to better guide your own teaching. Whether the quality of teaching activities can achieve the best teaching effect is the premise and foundation, and effective teaching design needs a teacher to have a comprehensive system theory to guide. Be good at learning new education and teaching theories, accept new knowledge, dare to meet new challenges, and take a road that others have not taken. The simple word "teaching design" is a systematic project and the key to carrying out teaching activities and completing teaching tasks. Information technology teachers should first study theory seriously, learn more and explore more, improve their own teaching design, and then better carry out teaching design of various disciplines with teachers of other disciplines.
