在小学数学教学中,学生的计算能力不是与生俱来的,而是通过理解算理和推导算法习得的。只有立足学生的数学起点,体现以人为本和算法多样化的教学理念,才能有效训练学生思维,提升学生的数学计算能力。在日常教学中,我们可以从以下几点着手培养学生的计算能力:要熟练掌握运算法则,保证计算结果的准确性;要具备初步估算能力,促进计算方法的技巧性;要切实加强口算训练,培养计算速度的快捷性;要善于采取简便算法,提升计算能力的发展性。
In elementary mathematics teaching, the computational power of students is not born, but learned by arithmetic and derivation algorithm. Only based on the students starting point of mathematics, reflecting the people-oriented and algorithm diversification of teaching philosophy, can effectively train students thinking and improve students’ mathematical ability. In daily teaching, we can start from the following points to develop students’ computing power: to master the algorithm, to ensure the accuracy of the calculation results; to have the ability to estimate the initial to promote the skills of calculation methods; to effectively strengthen the mouth training, Develop computational speed of the fast; be good at taking a simple algorithm to enhance the development of computing power.
