摘　　要：以“生物质橘皮果胶的提取及工艺流程设计”为主题,聚焦“生物质资源利用”社会热点问题,围绕有机化学、实验化学、工艺流程等高中化学重点知识开展项目式教学。引导学生完成有机物结构与性质探析、实验设计与优化、果胶提取及工艺流程设计等活动,深化对“结构决定性质”的理解,形成物质分离提纯的一般思路,构建工艺流程思维模型,体会生物质资源利用的途径和意义,提升其化学学科核心素养及问题解决能力。With the theme of“extraction of biomass orange peel pectin and process flow design”,focusing on the social hot issue of“utilization of biomass resources”,project-based teaching was carried out around key knowledge of high school chemistry,such as organic chemistry,experimental chemistry,process flow,and so on.Students were guided to complete activities such as organic structure and property analysis,experimental design and optimization,pectin extraction and process flow design,deepened the understanding of“structure determines property”,formed the general idea for material separation and purification,built the process flow thinking model,experienced the ways and significance of biomass resources utilization,and improved their core literacy in chemistry and problem-solving ability.
