Based on the perspective of engineering education accreditation certification

this paper analyzes the current situation and existing problems of experimental teaching in polymer materials and engineering majors

and proposes specific measures to reform experimental practice courses. Following the three core concepts of engineering certification (studentcentered

output-oriented

and continuous improvement) and focusing on the cultivation of students' ability to solve complex engineering problems

this major adjusts the course system and constructs a "chain" experimental course system to promote the seamless connection between theory and practice. The evaluation system of formative evaluation and resultoriented evaluation is established for the process evaluation of experimental practice curriculum implementation. By increasing the proportion of comprehensive and exploratory experiments and elaborately designing comprehensive polymer experiments

students' ability to solve complex engineering problems is improved.
