以问题驱动化学核心素养的培养——“钠与硫酸铜反应”的探究性教学

Teaching Design of “Reaction of Sodium and Copper Sulfate” Based on Creating Problem-Driven and Training of Core Literacy

基于科学探究的一般方法,从"钠和硫酸铜反应"的习题出发,以问题链为教学支架,根据学生认知结构,因材分组施教;通过改变反应条件引导学生由点到面地探究钠与硫酸铜溶液的反应,从而提升学生对化学变化的理解,培养学生的化学学科核心素养。

Based on the general method of scientific research, let the students do exercises of "the reaction of Sodium and Cupric Sulfate", then asks them to answer some questions in class. In order to meet the special requirements of each student, according to the students’ cognitive structure, teacher adopts the teaching method of group teaching. Finally, by changing the reaction conditions to guide students to explore the reaction of sodium and cupric sulfate. In this way,it can improve students’ understanding of chemical changes and cultivate students’ core literacy of chemistry.
