题目是巩固、反馈、提升、总结知识的一个纽带,更是由知识到能力的提升桥梁,因此,在我们的数学教学过程中,教师有必要深入研究题目,其中说题就是数学教师一项基本技能.本文以一道南通市中考题为例,进行说题案例分析,希望得到同行的认可和指点,以起到抛砖引玉的良好效果.第一、原题呈现(2010年南通市中考题第25题)如图1,已知:点B、F、C、E在一条直
The topic is to consolidate, feedback, upgrade, summarize the knowledge of a link, but also to enhance the bridge of knowledge to ability, therefore, in our teaching of mathematics, teachers need to study in-depth topics, which is the subject of mathematics teachers a basic Skills.This article take a Nantong city exam questions as an example, carry on the case analysis of the topic, hoping to get the recognition and guidance from peers, in order to play a good effect.First, the original title (Nantong City 2010 test questions 25 ) As shown in Figure 1, it is known that points B, F, C and E are in a straight line
