| 摘 要： | 本研究随机选取北京市三所普通幼儿园小、中、大班儿童共90名,采用实物操作的非言语任务,考察3-5岁幼儿在加减法运算中的策略发展特点。结果表明:随着年龄的增长,儿童使用的策略由模仿、交换向内化、相反数策略转化;3、4岁幼儿在相反数题中,更多使用模仿和交换策略,而5岁幼儿更多使用模仿、相反数策略;在标准型题中,儿童一般较多使用模仿和内化策略;最大表征对儿童策略选择存在影响。

| Abstract: | This study examined the developmental characteristics of strategies of 90 preschoolers' arithmetic calculations presented in a non-verbal form.The results indicated that with the growth of the children,the strategies children used transformed from the imitation strategy and exchange strategy to the covert strategy and inversion strategy.In inversion problems,children often selected the inversion strategy and exchange strategy;in standard problems,more children used the imitation strategy and covert strategy.The representational set size had influence on preschoolers' strategy choice. |
