Under the background of emerging engineering education, the training objectives and methods of engineering majors are constantly changing. Colleges and universities are entrusted with the mission of cultivating high-quality compound emerging engineering education talents. Curriculum becomes an important foothold of teaching reform. Material mechanics, serving as a foundational course within engineering disciplines, plays a pivotal role in the cultivation of innovative engineering professionals, and it is imperative to reform the course teaching. The teaching team analyzes the current teaching situation of materials mechanics, such as deeper theory, logic and engineering practice of the course itself, as well as problems existing in the course teaching such as uninspiring content, incomprehensible derivation process and rigid evaluation system. Based on the concept of outcome based education(OBE), the teaching team leverages the wealth of informational resources to explore the course content, teaching methods and assessment methods, and proposes the innovative teaching system of interest+understand+application (IUA). This system is designed to amplify student engagement, enrich comprehension of the material, and bolster the application of theoretical knowledge in practical contexts. The teaching of civil engineering and transportation in Southeast University is used as an example for practical research, by introducing engineering cases, enriching the classroom form by using internal and network resources and improving the course evaluation method. The effectiveness of the reform is tested through the survey of students’ classroom satisfaction, students’ knowledge mastery ability, and students’ extracurricular practice results.
