Abstract:Professional certification in engineering education is an internationally accepted quality assurance system for engineering education, and it is an important basis for international recognition of engineering education and qualification of engineers. Professional certification in engineering education requires that curriculum teaching should be designed in accordance with the outcome based education (OBE) concept, and the student-centered teaching model should be built. Finally, the closed-loop teaching mode is formed with continuous improvement mechanism. Environmental engineering microbiology is the core course of environmental engineering. Colleges and universities at home and abroad pay more attention to the curriculum reform, but there are some problems in the course setting and teaching methods. This paper focused on Environmental engineering microbiology, and discussed how to definite the contributions to graduation requirements, set curriculum objectives, develop the teaching syllabus, design experiments, track and evaluate students and monitor the quality, in order to achieve continuous improvement. It can provide theoretical reference for the curriculum teaching design under professional certification in engineering education.
