促进学生建立认识的初中化学教学设计——以“燃料的合理利用与开发”为例

Junior High School Chemistry Teaching Design to Promote Students'Understanding Establishment--Taking"Rational Use and Development of Fuel"as an Example

开发以核心素养为导向的教学案例是发挥学科育人价值的重要途径。本文从新课程标准的教学建议出发,开发促进学生建立认识的教学设计,以“燃料的合理利用与开发”为案例,阐述了如何基于变化的视角认识能量、基于能量变化的视角认识化学反应、基于能量变化和物质转化的双重视角认识化石燃料,探讨了学生从哪里出发、学生走向哪里、怎样知道学生到达了那里、学生如何到达那里、如何引领学生更好地到达那里,并分析了课程实施层面的着力点。

The development of core-literacy-oriented teaching cases is an important way to exert the value of discipline education.Based on the teaching suggestions of the new curriculum standard,this paper develops a teaching design that promote students to establish cognition.Taking"rational use and development of fuel"as an example,this paper expounds how to understand energy from the perspective of change,chemical reaction from the perspective of energy change,and fossil fuel from the dual perspectives of energy change and material transformation.It discusses where students start from,where students go,how to know where students have arrived,how to get there,how to lead students to get there better,and analyzes the focus of curriculum implementation.
