Under the background of 5G, the in-depth integration of information technology and higher education has become a new research trend, aiming at creating an information and intelligent classroom through the application of a new generation of information technology, and strengthening the cultivation of college students. Aiming at the problems existing in the teaching mode of application-oriented undergraduate colleges at present, adhering to the principle of student-centeredness, with the help of modern information means, the classroom and wisdom tools are organically combined, and a intelligent classroom teaching mode based on information technology is constructed by designing from teaching objectives, teaching modes, teaching activities and teaching evaluation. This intelligent teaching mode is applied in the course of engineering geology, and it is implemented in the Chaoxing learning platform. The teaching links are set along the thread of before class-during class-after class. Various preview materials are sent before class, all-round interaction is carried out in class, and personalized counseling is carried out after class. Finally, the online evaluation and offline evaluation are adopted to evaluate the teaching. The online part is mainly graded by platform teaching data and remote experts, and offline part is mainly graded by students’ participation and performance, pays attention to the process of assessment. Through the analysis of the teaching effect of this course, it is found that students’ academic performance, classroom participation and experience have been improved, which verifies the effectiveness of this intelligent classroom teaching mode and largely meets students’ learning needs. This mode highlights students’ dominant position in teaching, which is helpful for application-oriented undergraduate colleges to cultivate intelligent students, and provides a reference for the establishment of intelligent classroom teaching mode for courses related to civil engineering.
