一、体现数学思考的开放性数学教学中的开放性问题能够提高学生的深层次思维能力,培养学生在解决问题中的开放性和创造性思维,达到提高基本素质的作用。美国小学数学在考核小数的加法及大小比较时,会出现一个商店中的价目表并相应列出一些问题,比如:从这张价目表你能得到什么信息?你能怎样利用这些信息?用20元钱能买某两件东西吗?利用价目表提一个问题并解决。
First, the open mathematics teaching that reflects the open thinking in mathematics teaching can improve students ’deep thinking ability, cultivate students’ openness and creative thinking in solving problems and achieve the function of improving the basic quality. US elementary school mathematics When evaluating the addition and size of decimals, a price list in a store appears and lists some questions, such as: What information can you get from this rate card? How can you use this information? Use 20 Money can buy two things? Use the price list to raise a problem and solve.
