With the rapid development of science and information technology, the traditional mechanics classroom and teaching methods have been greatly impacted. The teaching method of mechanics should follow the development of science and technology, and the reform of mechanics teaching must be carried out.Taking engineering mechanics course as an example,which is a very important basic course for many engineering majors ,this paper points out the position and importance of this course in professional talent training program.According to the author"s years of teaching experience and summarizing the problems existing in the teaching practice of engineering mechanics course under the traditional teaching mode, the paper introduces the construction process of interactive mobile learning system based on learning mobile application, a hybrid teaching mode of "classroom teaching + application of interactive mobile learning system" is proposed, and undertake to the student satisfaction survey and teaching effect validation after the practice,,points out the advantages and disadvantages of such a hybrid method of teaching,provides reference for the teaching reform of mechanics course in universities.
