“几何直观”是《数学课程标准(2011年版)》提出的10个核心概念之一,一线教师在课堂教学中就如何更有效地体现、落实这一要求做了积极的探索。下面以北师大版三年级上册“加与减”单元中的“里程问题”的教学为例,谈谈我们在教学中如何借助直观图培养学生的几何直观。一、用“图”带题,图生图长用图解决问题或者说看图能力的培养并不是一朝养成的,需要日常教学中持之以恒的渗透。在教学时可以改变一下 “Geometric Intuitive ” is one of the 10 core concepts put forward in the “Mathematical Curriculum Standard (2011 Edition)”. The frontline teachers have actively explored how to implement and fulfill this requirement more effectively in the classroom teaching. The following to North China Normal University on the third grade volume “plus and minus ” unit “mileage problem ” teaching as an example, to talk about how we use visualization in teaching students to develop geometric intuition. First, the use of “Figure ” with questions, plans to use the map to solve the problem with long pictures or ability to see Figure is not a time to develop, you need to persevere in daily teaching infiltration.
