Abstract: In view of the deficiencies in the experimental teaching of “electronic technology” in non-electrical majors, combined with the requirements of this major for the cultivation of knowledge and ability of this course, the experimental teaching system in non-electrical majors is reformed with the “PBL (project-based Learning)” teaching method, and a systematic experimental teaching method aiming at solving practical problems is formed. With the limited class hours, students’ comprehensive skills of electronic technology experiment, that is the abilities of the circuit analysis, circuit design and circuit debugging are improved as far as possible. The experiment content is more interesting and challenging to stimulate students’ enthusiasm and innovation ability. Through the teaching practice, the effect of this teaching method has obtained good performance.
