计算能力是数学的基本能力,培养学生计算能力也一直是小学数学的主要目的之一,随着科技的发展,特别是计算器和计算机的普及,人们对计算教学的认识也在发生着变化。在传统的数学中,课堂教学采用的模式即基本训练、例题讲解、得出法则、巩固练习、最终形成技能。学生因计算的枯燥而缺乏兴趣,产生 Computational ability is the basic ability of mathematics. To train students’ computing ability has been one of the main purposes of elementary mathematics. With the development of science and technology, especially the popularity of calculators and computers, people’s understanding of computational teaching is also changing. In traditional mathematics, the model used in classroom teaching is basic training, explaining examples, drawing rules, consolidating exercises, and finally forming skills. Students lack interest due to the boring calculations
