【摘要】 以发展学生化学学科核心素养为主旨,分析了胶体教学内容的价值,通过创设一系列化学史情境,引导学生从化学史情境中提出问题,再以问题引领学习活动,使学生沿着科学家的研究历程展开实验探究,自主实验获取证据,基于实验证据进行推理,在主动建构胶体本质特性和性质的同时促进化学核心素养的发展。更多还原

【Abstract】 Focusing on the development of students’ core literacy of chemistry, the teaching value of colloid is analyzed. By setting a series of contexts about chemical history, the students are guided to put forward questions based on the chemical history, and then to lead the learning activity with questions. And in this way, students participate in inquiry activity along the footprints of scientists, collect evidence through independent experiments, and then reason based on experimental evidence, the essential characteristics and properties of colloids are constructed through this series of activities, and further, the core literacy is developed.更多还原
