教师边出示灰兔边问．”我今天请来的客人是谁呀?”幼J乙答道“小白兔”。教师又说“再仔细看看，它是谁?”幼儿回答“它是灰色的小白兔”。你从幼儿的回答中看出了什么问题?分析产生的原因，说说你从中可以吸取什么教训?
从幼儿的回答中，可以看出教师对幼儿的认知水平没有充分了解。该教师在各课这一环节没有做好没有备好学生．根据皮亚杰的认知发展理论，2岁到7岁阶段儿童认识活动的特点是：(1)相对的具体性。只能借助于表象进行思维活动，不能进行运算思维。(2)不可逆性。各种关系是单向的、不可返回的，没有守恒结构。(3)自我中心性。只能从自己的角度理解事物。(4)刻板性。在思考问题时，只能注意到某一方面，不能顾及其他。(5)缺乏概括事物性质的层次性。材料中，教师边出示灰兔边问“我今天请来的客人是谁呀?”幼儿答道“小白兔”。教师又说“再仔细看看，它是谁?”幼儿回答“它是灰色的小白兔”正是幼儿思维具有自我中心性的体现。吸取的教训是：教师课前备课一定多充分，应充分了解学生，多了解幼儿的发展特点，要在备课的过程中全方面了解幼儿。

For the road warrior
The new BlackBerry Storm is something likethe equivalent (等同物) of a mullet--a business up front, party in the back.
