计算器用起来方便,但并不能代替学生的计算。夯实计算能力是学好数学的基础,教师在教学中应有意识地培养学生的计算能力,可从以下几个方面进行:重视口算,为计算奠定坚实的基础;强化估算,培养学生对准确值的理解;关注笔算,培养学生认真学习的习惯;灵活简算,培养学生灵活运用的能力;建立机制,提高学生的耐心和细心;教给方法,培养学生检查验算的习惯。
Calculator is easy to use, but does not replace the student’s calculation. Consolidating computing power is the basis for learning mathematics. Teachers should consciously cultivate students ’computing abilities in teaching, which can be done in the following aspects: Emphasis on account calculation, laying a solid foundation for calculation; strengthening estimation and developing students’ understanding of accurate value ; Focus on pen calculations, develop students’ habit of earnest study; flexible and simple calculation, to develop the ability of students to use flexibly; to establish mechanisms to improve students’ patience and attentiveness; to teach methods to cultivate students’ habit of checking and checking.
