口算就是不借助计算工具,不用书面表达方式计算过程,依靠记忆,直接通过思维算出结果的一种计算方法。它是笔算的基础,具有用时少、容量大、形式活、速度快的特点,是训练思维敏捷性的良好手段。在现在的小学数学计算这一块的教学中,笔算显然占据了主要地位,这与笔算在各种计算中正确率较高是脱离不了关系的,而由于现在的评价机制——考试的分数这一催化剂的作用,使我们大部分教师更是重视学生的笔算。但是,虽说是笔算,但却不是纯粹的笔算,其中也或多或少穿插了口算的内容,如:除法笔算当中的试商,假如要一次性的试对,那口算就必定会参与。因此,小学数学应注重学生的口算能力训练。这些年来,我对口算技能这方面进行了一定的研究。 Mouth calculation is not a calculation tool, without written expression of the calculation process, relying on memory, calculated directly through thinking a result of the calculation method. It is the basis of pen calculations, with less time, large capacity, form and speed, is a good means of training thinking agility. In the current primary school mathematics calculation of this piece of teaching, the pen is clearly occupied a dominant position, which is calculated in various calculations with a high accuracy is inseparable from the relationship, and because of the current evaluation mechanism - the test scores this The role of catalyst, so that most of our teachers pay more attention to students’ pen calculations. However, although it is a pen calculation, it is not a pure pen calculation, which more or less interspersed with the mouth of the content, such as: division of pen trial among them, if you want to try one-off, then the mouth will certainly participate. Therefore, primary school mathematics should pay attention to the students’ oral ability training. Over the years, I have done some research on this area.
