[Exploration and practice of integrating "dual carbon" concept into the teaching of Microbiology]

To serve the national "dual carbon" goals and strengthen the role of higher education in cultivating talents for carbon sequestration and emission reduction, we focused on the main problems in current teaching practice and constructed a new teaching model for "dual carbon" education in Microbiology. Leveraging the online course resources, we systematically sorted out the knowledge system related to the "dual carbon" goals in Microbiology and reorganized the teaching contents through the dual approaches of embedding real-world production and daily life cases and dynamically tracking cutting-edge technologies. By designing a problem chain to guide the involvement of students and deeply integrating the "dual carbon" concept with course knowledge, this teaching model strengthens both the cognitive cultivation of "dual carbon" goals and the ability of microbial technology application. Teaching practice showed that this model effectively improved students' literacy of "dual carbon" goals and innovative ability, as well as teachers' teaching and research levels. The blended learning model developed in this study offers a referenceable paradigm for the teaching reform incorporating "dual carbon" concept in university courses and has demonstrative significance in fostering "profession+green" composite talents needed in new era.
