基于核心素养培育的“课堂留白”研究

Research on “Leaving Blank Space for Classroom Teaching” Based on Cultivation of Core Literacy

为解决“应试教育”下高中数学课堂教学节奏快、知识密度高,以及学生缺乏独立思考和交流合作机会、自主学习能力下降等问题,将“课堂留白”作为构建和谐课堂教学生态的重要手段.从“课堂留白”的内涵出发,明晰核心素养培育与“课堂留白”之间的逻辑关系,分别从单元大概念下的“课堂留白”、课时小概念下的“课堂留白”、知识微概念下的“课堂留白”3个层面,逐层阐述“课堂留白”的教学策略,并结合实例阐述“课堂留白”的有效实施方法.

In order to solve the problems of high school mathematics classroom in the background of the“exam oriented education”,such as fast teaching pace,high density of knowledge,students’lack of independent thinking ability and opportunities of communication and cooperation,and the degradation of independent learning ability,this paper takes“leaving blank space for classroom teaching”as an important means to constructing a harmonious classroom teaching ecology.Starting from the connotation of“leaving blank space for classroom teaching”,the paper clarifies the logical relationship between the cultivation of core literacy and“leaving blank space for classroom teaching”.This paper expounds“leaving blank space for classroom teaching”from three levels:“leaving blank space for classroom teaching”under the big concept of a unit,“leaving blank space for classroom teaching”under the small concept of a class session,and“leaving blank space for classroom teaching”under micro concept of knowledge.Then,the teaching strategy of“leaving blank space for classroom teaching”is expounded layer by layer,combined with the effective implementation method of“leaving blank space for classroom teaching”with examples.
