Engineering Certification Practice Teaching Management and Data Mining Based on Complex Hierarchical Model

With the rapid development of education, especially the rapid development of higher education, the informationization and modernization level of education management have made great progress, and universities have made gratifying achievements in management information system. Engineering education professional certification brings opportunities and challenges to China's higher education: on the one hand, it can promote us to improve the teaching quality and let graduates obtain internationally recognized qualification certificates. On the other hand, higher educators need to change their thinking, think backwards from the perspective of teaching output, and re-examine teaching input, so as to better cultivate graduates who meet the engineering certification standards. Educational data mining is a process of transforming the original data from educational administration system and teaching system into useful information. Based on the complex hierarchical model, this paper constructs the university practical teaching system, quantifies students' practical ability in the form of credits, and brings it into the student evaluation system, which can reflect students' personal ability more comprehensively.
