经常听到学生这样评价数学:数学是枯燥的、乏味的,缺少趣味性,让人昏昏欲睡。这种观点虽然比较偏激,但至少从一个侧面反映了过去相当长的一段时间里,我国中学数学教学的消极状态。反思一下,我们不难得出这样的结论,我们提供给学生的数学未必是有价值的,未必是所有人必须的。其实,生活是美的,而生活中因为有了数学就变得更美。但是为什么学生没有感觉到呢?除了教材的原因外,作为教师我们也要好好检讨一下自己的教学,我们的教学设计。新的数学课程标准提出了“情境创设探索活动——例题教学——思维拓展”基本教学模式,要求教师在教学中应从学生实际出发,创设有助于学生自主学习的学习情境,引
Students are often heard to rate math like this: math is boring, boring, lacking in interest, and makes people drowsy. Although this point of view is rather extreme, it reflects at least one aspect of the negative state of mathematics teaching in secondary schools in our country for quite a long time. Reflecting on it, it is not hard for us to conclude that the math we provide to students is not necessarily valuable and may not be necessary for all. In fact, life is beautiful, and life is more beautiful with math. But why do not students feel it? In addition to the reasons for teaching materials, as a teacher we have to carefully review their own teaching, our teaching design. The new mathematics curriculum standard puts forward the basic teaching mode of “exploring the situation, setting up the teaching of the case, thinking expanding,” asking the teacher to set out from the reality of the student and create a learning situation that helps students to learn independently.
