平平看到老师在倒水：老师把一个矮而宽的杯子里的水，倒人另一个高而窄的杯子中，平平就认为水变多了，因为水看起来“长”了。有一次，他想帮妈妈洗鞋子，就把鞋子放入盆中，用刷子刷起来，却没有放水和擦肥皂。
问题：请根据有关幼儿思维特点的原理，对此案例作出分析。
正确答案及解析
正确答案
解析
这种现象表明了幼儿的思维具有具体形象并派生出片面性的特点。 平平之所以认为水变多了，是因为他在解决问题中常常只是照顾到事物的一个维度(因为水看起来“长”了)，而不能同时兼顾到两个维度，不能把握高矮与宽窄两个维度相互联系。他想帮妈妈洗鞋子，就把鞋子放入盆中，用刷子刷起来，却没有放水和擦肥皂，这就是因为他只知其一，不知其二。幼儿思维的片面性常常使幼儿“好心办坏事”。

For the road warrior

For the Luddite (反对技术进步的人)
