3～6岁幼儿数守恒和长度守恒的发展特点

On the Development of Young Children's Number and Length Conservation

不同年龄阶段的幼儿在数守恒和长度守恒方面具有不同的发展水平。小班幼儿极易受物体排列形式的影响,部分中班幼儿仍摆脱不了物体排列形式的影响,大班幼儿初步形成了数的守恒。幼儿长度守恒的发展落后于数守恒的发展,其发展顺序与皮亚杰的研究结果一致,但形成年龄略微提前。

The development level of children＇s conservation marks that of their thought. Children at different ages have different level of number and length conservation. The study＇s results are in accordance with Piaget＇s, though the forming ages come a little earlier than before.
