聚焦核心问题 激活数学课堂

Focus on Core Problems to Activate Mathematics Classroom

数学是从问题开始的,问题是数学学习的源泉和不竭动力。核心问题是一堂课的“课眼”和“主线”,也是学生学习的重难点。在实际教学中,教师要巧妙设置核心问题,促使学生在核心问题的引领下习得知识、获得能力、发展思维。文章从立足核心问题、化堵为疏,围绕核心问题、去粗存精,聚焦核心问题、化静为动,抓住核心问题、化繁为简,着眼核心问题、先予后取,把握核心问题、刨根究底等方面入手,对基于核心问题的数学课堂教学策略进行探究。

Mathematics begins with problems.Problems are the source and inexhaustible driving force of mathematics learning.The core problem is the"eye"and"main line"of a class,and it is also the key and difficult point of students'learning.In practical teaching,teachers should skillfully set up core problems to promote students to acquire knowledge,acquire ability and develop thinking under the guidance of core problems.This paper explores the mathematics classroom teaching strategy based on the core problems from the aspects of basing on the core problems,turning blocking into dredging,focusing on the core problems,removing coarse and storing fine,focusing on the core problems,turning static into dynamic,grasping the core problems,taking things first,grasping the core problems,and studying the root causes.
