在小学数学教学中,我们从以下四个方面进行改进,取得较好的教学效果. 一、以旧引新,温故知新数学是许多概念组成的锁链.旧的数学概念是学生学好新概念的基础,新概念又是旧概念在新条件下的扩展、引伸和发展.因此,在教学新概念时,可适当对有关的旧概念进行复习,并注意在旧概念的锁链上加入新的环节,温故知新,进而学好新的数学概念. 例如,我们在教学“多位数的读法和写法”时,就可从复习“万以内数的认识开始,特别应重点复习万以内数的读数法则,为学生学好多位数的读写打下基础.
In primary school mathematics teaching, we improve from the following four aspects to obtain better teaching effect: First, using old and new to learn new mathematics is the chain of many concepts.Old mathematics concept is the basis for students to learn new concepts, The new concept is the expansion, extension and development of the old concept under the new conditions, therefore, when teaching new concepts, the old concepts can be properly reviewed, and new links should be added to the old concepts, For example, when teaching “multi-digit reading and writing”, we should start with the review of “within one million counts,” and in particular, we should focus on reviewing the reading rules of within one million, A lot of reading and writing lay the foundation.
