Teaching Design of“Material Classification”From the Perspective of Functional Value

对功能价值视角下"物质的分类"教学设计进行分析,从教学目标和教学过程入手,发现分类方法学习能够提高学生的自我管理水平,具有生命价值;分类结果学习能够加深物质性质学习的深度,具有学科价值;分类知识运用能够预测新物质的性质,具有实用价值,实现了学生在宏观辨识、变化思想、证据推理、模型认知中发展化学学科核心素养的目的。

This paper analyzes the teaching design of"material classification"from the perspective of functional value.Starting from the teaching objectives and teaching process,it is found that the learning of classification method can improve students’self-management level and has life value;the learning of classification result can deepen the learning of material property and has subject value;the application of classification knowledge can predict the property of new material and has reality with value,the purpose of developing the core literacy of chemistry discipline in the macro identification,change thinking,evidence reasoning and model cognition is realized.
