Abstract: The students who are cultivated are severely out of line with the social needs in many colleges and universities, and the enterprises are unable to use them directly at present. According to the concept of engineering certification and the needs of enterprises, the traditional practice teaching methods and means should be changed to allow students to participate in various innovative practical activities in the laboratory, so as to improve their ability of solving complex engineering problems, innovation, practice and team collaboration. Taking Electronic Information Engineering Specialty as an example, according to the comparison of employment quality data before and after education reform, it can be found that the practical teaching reform under the OBE educational concept is conducive to improving the employment quality of graduates.
