Abstract: With the continuous development of information technology, modern education has undergone fundamental changes in teaching content, teaching methods, teaching implementation and other aspects [1]. Taking "the application of quick return characteristics" as an example, this paper expounds the application of information technology in the course of "Fundamentals of mechanical analysis and application" from five aspects: teaching analysis, teaching design, teaching implementation process, teaching effect and characteristic innovation. Through the use of information technology, students' interest in learning can be aroused, students' enthusiasm in learning can be aroused, teaching key points and difficulties can be effectively solved, and teaching effect can be improved.

Key words: Informatization, Teaching design, Application of quick return characteristics, Basic mechanical courses
