Abstract: Under the background of engineering certification, in order to improve students' engineering innovative thinking ability, the experimental teachers studied the student-centered teaching concept and heuristic teaching form; Combined with the index requirements of engineering certification, this paper studies the innovation of experimental teaching design and experimental teaching form, and thinks about the cultivation of students' innovative thinking ability; As the supplement of offline experiment and response to the special environment, the online experiment teaching is studied according to the requirements of engineering certification index. This research provides a reference for improving students' engineering innovative thinking ability.

Key words: Experiment teaching, Innovation research, Engineering certification, Mechanical and electrical specialty
