Abstract: Solid theoretical knowledge of Finite Element Method course is a guarantee for master's students to carry out deeper and broader scientific research, and also basis for students to analyze mechanical structure mechanics and apply structural optimization design．Based on analysis of existing theoretical teaching problems of current course, theoretical teaching content of Finite Element Method course was adjusted systematically, and new teaching sessions such as bilingual teaching and classic literature guide were introduced．This made teaching content focused, thinking became clear, steps were gradual, times were advanced, and complicated knowledge points were well sorted out, overcoming obscure phenomenon caused by lack of solid basic knowledge of mathematics and mechanics and helping students accurately establish concept of knowledge system．Practice has proved that reform of theoretical teaching content improved academic performance of graduate students in agricultural mechanical engineering, helped to improve quality of talent training, and met target needs of high-quality talent training for master's students of Qingdao Agricultural University．
