摘　　要：微项目式教学是培育义务教育阶段学生化学核心素养的可行路径。以“皮蛋的制作和食用”真实生活情境为例,呈现了初中化学“酸、碱、盐的化学性质系统复习”的微项目式教学实践。在“选料”“调浆”“裹泥”“封存”“食用”和“课后实践”等子项目的逐步推进中设计问题情境、挖掘核心知识及构建知识框架,发展学生分类、分析、归纳、综合的科学思维,建构运用化学知识解决生活实际问题的化学观念。Micro project teaching is a feasible method to cultivate the core competency of chemistry in the stage of compulsory education.Focused on"manufacture and consumption of preserved egg"as the micro project theme,a micro chemistry teaching project titled"systematic review of chemical properties of acid,alkali and salt"in a junior high school was implemented.This project comprised six sub-projects:material selection,mud blending,encase egg with mud,seal preservation,consumption,and after-class practice.In the process of accomplishing six subprojects,the instructor created problem situation,and excavated key knowledge,as well as established knowledge framework,helping students develop scientific thinking in classification,analysis,induction and synthesis.It also intended to engage students in applying chemical knowledge to solve practical problems in their daily lives.
