摘要 以“我是零碳甲醇工程师”为主题,以“设计零碳甲醇生产方案”为驱动性任务,在“物质变化与转化”大概念的统领下开展教学。通过本课程的学习,在学习质量守恒定律和化学方程式等核心知识的同时,引导学生建立“利用质量关系、比例关系”认识化学反应的思路。将化学方程式知识的学习与定量认识化学变化角度的建立相统一,实现化学方程式的功能化学习。学生通过计算推演体会合理利用物质、调控化学反应的重要性。 With the theme of"I am a zero carbon methanol engineer"and the driving task of"designing a zero carbon methanol production plan",teaching is carried out under the guidance of the concept of"material change and transformation".Through the study of this project,while learning core knowledge such as the law of conservation of mass and chemical equations,students will be guided to establish a mindset of understanding chemical reactions through the use of mass relationship and proportional relationship.The purpose is to achieve functional learning of chemical equations by integrating the learning of chemical equation knowledge with the establishment of a quantitative understanding of chemical changes,and finally students can gain a deeper understanding of the importance of rational use of substances and regulation of chemical reactions through computational deduction.
