China Engineering Education Accreditation (CEEA) is put forward under the background that engineering education in China is in line with international standards. Its concept of "student-centered, outcoming-based and continuously improving" education is of great significance to guiding modern engineering education and training engineers with both technical and non-technical abilities. According to the requirement of outcoming-based education (OBE), the structural mechanics course group of Civil Engineering College Chongqing University, started from the learner's cognitive rules of constructivism, analysed the content characteristics of structural mechanics course and its position in the curricula system, applied backward design method to design the hybrid teaching model, which includes teaching methods and tools such as lectures, SPOC-based learning, task-oriented teaching and conversational framework. At the same time, practical engineer projects is introduced into the teaching design to cultivate students' ability to solve "complex engineering problems", so as to achieve the teaching goals and meet the corresponding CEEA graduation requirements.
