二氧化硫性质的实验创新及探究教学设计

On The Innovative Experiment of Sulfur Dioxide's Nature and Exploration of the Teaching Design

文章针对"二氧化硫性质"知识教学重难点,以探究的思维方式分别设计了两个创新实验证实"可逆反应"的真实存在与探究二氧化硫漂白性的实质,并通过教学设计,生动展现二氧化硫溶于水的可逆动态过程,升华学生对化学基本原理和知识实质的理解,体现新课改理念,把培养学生的探究能力作为科学课程的核心目标。

In the light of the teaching difficult points of the nature of sulfur dioxide,the paper designs two innovative experiments to prove the existence of the reversible reaction,explores the the essence of the sulfur dioxide＇s bleachability,shows the reversible dynamic process of the dissolving of sulfur dioxide in water,strengthening students＇ understanding of basic chemical theory and knowledge,reflects the concept of new curriculum reform,and takes the cultivation of students＇ research ability as the core of science subject.
