摘 要:该研究通过 3项系列实验探讨了学前至小学低中年级儿童理解、掌握和应用“零”概念的发展水平。结果表明 ,学前至小学低中年级儿童对“零”概念的理解、应用“零”进行加减运算、乘除运算的能力都是不断提高的。但是 ,对于把“零”作为除数或被除数的理解要落后于将其作为乘数或被乘数使用的理解。最后 ,综合三项实验结果进行了总体讨论。experiments were conducted by presenting a series of picture which have kinds of inference with each other. Experiment 1 showed that the understanding of'zero' concept in children from 5~9 years old develop with aging; Experiment 2 also indicated that the ability of using 'zero' to plus or subtract with other numbers in children aging from 5 to 8 increase; Experiment 3 demonstrated that the ability of using 'zero' to time or eliminate with other numbers in children aging from 8 to 9 develop with aging, but , the ability in the application of zero as a divisor or dividend is less than that in the application of zero as a multiplier or multiplicand. In the end, the discussion is carried out by the three outcomes.
