Based on the concept of engineering education accreditation and the 12 graduation ability requirements, taking the course of introduction to road, bridge and river-crossing engineering as an example, the knowledge system of professional introduction course is reconstructed and divided into four parts and taught by four knowledgeable teachers separately, and freshmen entrance education ability training guidance, bilingual teaching, ideological and political education in curriculum are involved. It is organized by group teaching in class. For the course multi-level evaluation system design, online video watching task, complex engineering problem thinking, team question-based competition, team special topic presentation, and course paper writing are introduced. To strengthen or improve the relationship between teachers and students or teaching and learning, communication platform is established for all professional teachers and students to achieve continuous guidance, otherwise, the frame of "30 years linkage between teachers and students" is created for sharing alumni experiences into introduction course and assistance of specialty construction. Through several rounds of reformation and practice, the experience can provide useful reference for similar engineering introduction courses.
