Research on the Sustainable Improvement Mechanism of the Chemical Engineering and Technology Major Based on the Concepts of Outcome-Based Education–Plan-Do-Check-Act (OBE–PDCA) in Engineering Education

This study examines the Chemical Engineering and Technology major at Nanjing Forestry University as a case study to explore a sustainable improvement and development model for the major, grounded in the principles of Outcome-Based Education (OBE) and the Plan-Do-Check-Act (PDCA) framework. In the context of new engineering education and integrating the core concepts of engineering professional education accreditation, this research merges the OBE concept with the PDCA model to promote the sustainable enhancement of the Chemical Engineering and Technology major. The objective is to assess the effectiveness of this professional construction model based on the OBE and PDCA framework in fostering the sustainable development of students. The findings indicate that by establishing a cultivation system aligned with the new economy, restructuring the interdisciplinary curriculum, and implementing a diversified evaluation system, it is feasible to nurture high-quality technical engineering talents equipped with social responsibility, teamwork skills, innovative thinking, and an awareness of sustainable development. This study demonstrates that this professional construction mechanism and model significantly contribute to developing sustainable education, enhancing engineering practice and innovative awareness, and cultivating applied innovative talents among students. Furthermore, this study not only offers new insights for specialty construction but also serves as a practical reference for improving teaching quality and meeting societal demands.
