我校从1991年开始,把珠算式心算训练作为“三算结合”实验的一个重要的实验因子。经过四年多的不懈努力,现已取得了比较明显的效果。我校的珠算式心算训练工作是从以下三方面来开展的。 一、正确认识珠算式心算训练的优势 珠算式心算训练,其实质是在强化珠算技术训练的基础上,使学生在脑中形成珠算的表象,进而利用珠算表象进行熟练的心算。因此,对小学生来说,珠算式心算有着比较突出的优势。 首先,珠算式心算训练符合小学生的认知特点。
Since 1991, our school has adopted abacus arithmetic training as an important experimental factor in the experiment of “three calculations and combination”. After more than four years of unremitting efforts, more obvious results have been achieved. My school's abacus mental arithmetic training work is carried out from the following three aspects. First, a correct understanding of the adolescent abacus mental arithmetic training Abacus mental arithmetic training, its essence is to strengthen abacus technology training based on the students in the brain to form abacus representation, and then use the Abacus representation proficient mental arithmetic. Therefore, for primary school students, abacus mental arithmetic has a more prominent advantage. First of all, abacus mental arithmetic training is in line with the cognitive characteristics of primary school students.
