一、前言“珠算式心算”是指借助内化了的“心理算盘”,在头脑中快速高效地进行复杂的数量计算的一种独特的计算技能。计算能力是个体数学能力的基础与核心成分。[1]20世纪80年代初以来,浙江省慈溪市以鸣鹤镇中心小学为代表的一批学校通过“珠算式心算”(简称“珠心算”)的教学 I. INTRODUCTION “Abacus” is a unique computational skill that makes complex, quantitative calculations in the mind quickly and efficiently with the help of an internalized “mental abacus.” Computational ability is the basis and core component of individual mathematical ability. Since the early 1980s, a group of schools represented by the Central Primary School of Minghe Town, Cixi City, Zhejiang Province have adopted the teaching of “Abacus Calculation” (“Abacus calculation” for short)
