Application and Practice of CBI Teaching Mode in “Professional English” for Materials Science and Engineering

: In order to change the traditional teacher-centered teaching method in the "Professional English" and improve the students' application ability of "Professional English", CBI (Content Based Instruction) teaching method is introduced into the "Professional English" course for undergraduates majoring in materials. This method emphasizes the autonomous learning method based on the content of materials science and engineering, so as to strengthen the cultivation of students' comprehensive quality, improve students' ability to apply English in the professional field, and stimulate students' autonomous learning initiative and learning efficiency. Using the literature search method, students can choose their own professional knowledge and preview before class. Using the flipped classroom method, students are encouraged to carry out teaching activities in the class, such as trial lectures and classroom discussions. A process assessment based on classroom performance has been established. The results show that students' ability to express themselves in professional English has been strengthened and their learning efficiency has been generally improved. The course assessment process is more reasonable. Compared with the results of the previous school year, the average score
