摘要：

依托国家级一流本科课程，融合PBL (Problem-Based Learning)开展混合式课堂教学，设计了PBL教学案例——“碳达峰碳中和”中的无机化学问题探究。引导学生从大气中CO2污染产生的化学反应过程入手，分析基于降低碳排放开发的CO2转化新技术的化学反应原理，探讨不同CO2转化技术的优势和劣势。通过PBL教学实践，将化学理论与工业实践深度融合，在夯实理论基础的同时，使学生的学习能力和解决问题能力得到提升。通过思政教育有机融入，使学生了解到我们国家科技的进步，体现课程教学的立德树人。

Abstract:

Based on the national first-class online course of inorganic chemistry, the online and offline hybrid classroom is carried out by integrating with PBL (Problem-Based Learning) teaching mode. A PBL problem is designed to explore the related inorganic chemistry knowledge in "carbon emission peak and carbon neutralization". The students start with the chemical reaction process respected to the CO2 production, analyze the chemical reaction principle related to the new CO2 conversion technology aiming at reducing carbon emissions, and discuss the advantages and disadvantages of different CO2 conversion technologies. With the help of PBL teaching mode, the students may well integrate the theory and practice, and consolidate the theoretical foundation, as well as improve the students' learning ability and problem-solving ability. Moreover, through the introduction of ideological and political education, the students can also find the progress in science and technology in our country, which realizes the moral cultivation of the course teaching process.
