摘　　要：以“探秘铁肥的合理使用”为主题,开展高中化学“铁及其化合物”的项目式教学。通过完成“确定铁肥的主要成分”“检验铁肥是否变质”“铁肥的合理使用”等3个任务,学生学会不同价态铁元素化合物的转化和检验方法,形成从元素价态和物质类别角度探究物质性质的思路。初步培养了实验探究能力,提升创新意识,发展基于“铁及其化合物价-类二维模型建构”的模型认知素养。学生收获了真实新颖、亲身实践、分组合作、交流展示等成就性体验,制作的铁肥保存和合理使用说明书体现了项目式教学的本质特征,实现学习结果的可视性、共享性、交流性。To explore the rational use of iron fertilizer as the theme,carry out the teaching of“iron and its compounds”in high school chemistry.By completing the three sub-tasks of“determining the main components of iron fertilizer”,“checking whether iron fertilizer is metamorphic”and“rational use of iron fertilizer”,students learn the transformation and inspection methods of different valence iron element compounds,forming the thinking of exploring the substance properties from the two perspectives of elemental valence state and substance category.It has preliminarily cultivated experimental inquiry ability,improved innovation consciousness,and developed model cognitive literacy based on the“valence-classification two-dimensional model of iron and its compound”.Students have gained real and novel,hands-on practice,group cooperation,exchange and display of achievement experience,the production of iron fertilizer reasonable use manual reflects the essential characteristics of project-based teaching,to achieve visibility,sharing,communication of learning results.
