《标准(2011版)》在“学段目标”中提出“观察物体的相对位置和形状,掌握图形与几何的基础知识和基本技能,建立空间观念,初步形成几何直观能力,发展形象思维和抽象思维”。由此可见,“观察物体”其课标要求的核心目标为“培养学生的空间想象力和思维能力”。根据这一要求,我就比新旧教材的变化、不同版本教材的呈现特点,细问自己:本课的数学本质是什么?教育的价值又该如何凸显?一、填空改连线,直逼教学目标 The Standard (2011 Edition) put forward in “Target of a Course” to observe the relative position and shape of an object, master the basic knowledge and basic skills of graphics and geometry, establish the concept of space, initially form the geometric intuition and develop the image Thinking and abstract thinking “. Thus it can be seen that the core objective of ”observing objects“ for its course requirements is ”cultivating students’ spatial imagination and thinking ability". According to this requirement, I am better than the changes of old and new textbooks, different versions of the textbook presentation features, ask yourself: What is the mathematical nature of this lesson? The value of education how to highlight? First, fill in the blank to change the connection, almost equal to teaching aims
