Abstract: The cultivation of innovative talents is a new requirement of social development to higher engineering education.How to set up the practical teaching system which is conducive to the students' engineering practice ability and innovation ability is one of the core contents of personnel training.The purpose of this paper focuses on improving the practice and innovation ability of undergraduate students major in Measurement Control Technology and Instrumentation.Based on the analysis of students' engineering quality and practical skills,the paper divides the practical skills into basic level practice,professional practice,and engineering practice.It discusses the dependency relationship between the ability cultivation at all levels and the teaching practice of curriculum practice.Put forward the design scheme and the concrete implementation way of the all-round practice teaching system in the undergraduates study.
