简述影响幼儿操作技能形成的因素。
正确答案及解析
正确答案
解析
(1)知识经验。幼儿知识经验相对匮乏，因此只能根据其年龄特点学习一些与其自身生活密切相关的、相对简单容易的技能。(2)准确地示范与讲解。①操作技能的学习始于教师的讲解。教师的讲解要尽量做到简单、易懂，多用一些幼儿容易理解的语言。②教师要保证示范的正确性和有效性，把握示范的时机，使幼儿清楚地看到教师的示范。
(3)必要而适当的练习。练习是形成各种操作技能所不可缺少的关键环节。通过不同形式的练习，不断增加练习的次数等形式，个体会掌握某种技能，而且动作的精确性、速度和协调性会逐步地提高。
(4)充分而有效的反馈。一般来讲，反馈来自两个方面：①内部反馈，即操作者自身的感觉系统提供的感觉反馈；②外部反馈，即操作者自身以外的人和事给予的反馈，有时也称结果反馈。

阅读下面关于戊戌变法的两种课堂总结方式，回答问题。
方式一：为摆脱民族危机和发展资本主义，民族资产阶级掀起了一场维新变法运动，这是先进的中国人探索救国道路的又一次尝试，虽然失败了，但是它就像一粒火种在中华大地上燃起。前仆后继的中国人又开始新的探索，一场更大的风暴即将掀起。
方式二：纵观中国历史上的改革，有成功的，例如商鞅变法使秦国慢慢强大起来，北魏孝文帝改革促进民族融合；也有失败的，例如我们今天学习的戊戌变法，虽然失败了，但是客观上也推动了中国社会的发展和进步。是符合历史发展潮流的。

For people who don′t read instructions
The easiest-to-use phone is the iPhone. It′sthat has pushed it to the No.1 selling position, surpassing the Motorola Razr.The iPhone′s touch screen is easy to operate and it′s also easy to customize (用户化). The iPhone can run allsorts of applications such as those help you to lose weight, identify a song onthe radio, find a restaurant or do many other things.
For the futurist
The T-Mobile G1 is very popular as it is thefirst phone to offer a Google browser, meaning that you′re getting the real webon your phone, but it′s the phone′s potential that qualifies it for the futurist.The exciting applications are interesting, but they don′t always work smoothly.Sometimes it is hard to use the applications it comes with. The system shouldimprove as it becomes more popular, so it holds great promise. With fewrestrictions on the design of applications for the phone,
the G1 could be the first phone toincorporate (整合) some of the coolest.
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. It stillincorporates the serious mail and organization features that have endeared (使受钟爱) these phones to business people. The 3.25-inch is bright anddetailed and it′s a decent size for watching videos on the go.
For the Luddite (反对技术进步的人)
For those who can′t handle buttons and newfeatures, there is the Samsung Jitterbug Dial. Some people are Luddites whojust want a few large buttons to make calls. That′s it, just calls. That makesit even easier to use an iPhone.
