儿童数量表征能力与“数与代数”学习经验的关系

研究主要探讨一年级儿童的数量表征能力与"数与代数"学习经验的关系。实验选取61名完成"100以内数的认识"和"100以内数的加法与减法"学习的儿童,对他们进行0~100和0~1 000的数字线估计任务的测量。结果发现:儿童的数量表征能力受到"数与代数"的学习经验的影响。"数的大小"的学习经验均会影响儿童的数量表征能力。"数的运算"能力强弱影响儿童数量表征的结果和策略。

Relationship between Numerical Representation and Learning Experience of“Number and Algebra”

In order to explore the relationship between numerical representation and learning experi-ence of“number and Algebra”, the study examined 61 first graders who have learned“the comprehension within 100”and “the addition and subtraction within 100”. They are asked to finish the 0~100, 0~1000 number line estimation tasks. The results show that: (1) Numerical representation of first graders is influ-enced by the learning experience of “number and Algebra”. (2)The learning experience of “numeric com-parison” affects the numerical representation. (3) Results and Strategies of numerical representation are influenced by operational capability.
