摘要
2017版高中化学课程标准提出了“发展学生化学学科核心素养”的要求。因此,在化学课堂教学中,教师应全面贯彻“化学学科核心素养”的课程理念。通过化学学科核心素养理念下“钠与水的反应”这节课的教学设计与实施,尝试在一节课的教学中如何贯彻培养学生5个方面化学学科核心素养的思想。具体教学用“金属引发的爆炸”为真实情景引入,通过准确表达钠与水反应的宏观现象,解释此反应的微观本质,进一步理解“结构决定性质”的化学观念,用化学方程式将化学反应准确书写下来,并让学生用所学知识解决生活中的实际问题,从而达到培养学生化学学科核心素养的目的。
The 2017 version of the senior high school chemistry curriculum standards proposes the main theme of the chemistry curriculum—"Developing Students'Core Literacy in Chemistry".Therefore,in chemistry classroom teaching,teachers should focus on the curriculum concept of"core literacy of chemistry".Through the teaching design and implementation of the"Reaction of Sodium and Water"lesson under the concept of core literacy in chemistry,this article attempts to show how to train students in the five aspects of core literacy in chemistry in one class.The specific teaching introduces the"metal-induced explosion"as a real scenario,accurately expresses the macroscopic phenomenon of the reaction between sodium and water and explains the microscopic nature of the reaction for students to further understand the chemical concept of"structure determines properties".Students use chemical equations to transform chemistry reactions accurately,and use what they have learned to solve practical problems in life,so as to achieve the purpose of cultivating the students'core literacy in chemistry.
