基于化学学科核心素养的实验改进设计——以“分子和原子”为例

Experimental Improvement Design Based on Chemistry Discipline Core Literacy——Taking"Molecules and Atoms"as an Example

教师要基于化学核心素养来进行实验改进设计,这不仅可以帮助学生更好的理解基础理论知识而且对于化学学习的兴趣也会加大。在实验改进设计时,深度挖掘教材,注重联系生活实际,培养学生的探究意识,使学生感受到化学的乐趣,提升其化学学科核心素养。改进和设计实验能够增强化学实验的可观察性和有效性,所以教师可以适当对教材上的实验进行创新改进,做到装置简单、操作简便,实验效果好。以“分子的运动”这一实验的改进为例,提出对原实验的改进方案,这样既能提升实验效果,又可以培养学生的化学素养。

Teachers should conduct experimental improvement design based on chemistry core literacy,which can not only help students better understand basic theoretical knowledge,but also increase their interest in chemistry learning.In the experimental improvement design,paying attention to the actual life,cultivating students'sense of inquiry,making students feel the fun of chemistry,can improve their chemistry discipline core accomplishment.For chemical experiments in schools,improving and designing experiments can enhance the observability and effectiveness of chemical experiments,so teachers can innovate and improve the experiments in teaching materials appropriately,so as to achieve simple devices,simple operation and good experimental results.Taking the improvement of the experiment of"molecular movement"as an example,this paper puts forward the improvement methods of the experiment,which can not only improve the experimental effects,but also train their chemical accomplishment.
