计算能力是小学生必须形成的基本技能,是学生今后学习数学乃至其他相关学科的基础。在小学各年级的计算教学过程中,在潜移默化中努力培养学生的计算能力,是数学教师应牢牢把握的原则。1.明晓算理,掌握算法。明晓算理,掌握算法是计算教学的核心任务。学生只有理解了计算的道理,才能“创造”出计算的方法,才能理解和掌握计算方法,正确地计算,所以计算教学必须从算理开始,要着重帮助学生应用已有的知识领悟计算的道理。
Computational ability is the basic skills that pupils must form, and is the basis for students to learn math and other related disciplines in the future. In the process of calculating teaching in all grades of elementary school, trying hard to cultivate students’ calculating abilities is a principle that mathematics teachers should firmly grasp. 1. Ming Ming arithmetic, control algorithm. Clearly understand, grasp the algorithm is the core task of computing. Only when the students understand the reasoning of calculation can they “create” out of the calculation method to understand and master the calculation method and calculate correctly. Therefore, calculation teaching must begin with the calculation and focus on helping students apply the existing knowledge to comprehend the calculation The truth.
