小学生起步作文,片断训练是十分重要的。怎样培养学生的观察能力,联想能力,在三年级进行扎扎实实的片断训练呢?1.利用课文插图进行片断训练三年级课文的插图多,这也就是编者有意培养学生多观察的素材。在学生理解课文内容和插图的前提下,“剪下”插图的某一组画面,让学生进行片断的训练。例如,《放风筝》这幅图画的是“我和哥哥”及 相似文献

片断在学习《不用文字的书和信》(新世纪版小学《语文》三年级下册第十一单元)一文的第二自然段时,我让学生根据文本所提供的内容,结合自己已有的生活经验,对“贝壳记事”的方法进行大胆而合理的猜想。学生们那些富有创意的回答,令我惊叹不已。师:请同学们大胆地猜想一下,在没有文字的民族中,他们是如何用贝壳进行记事的。(学生们沉思了一会儿,纷纷举起了小手)生:他们会用白色的贝壳表示白天发生的事情,用黑色的贝壳表示夜晚发生的事情。师:你的猜想很有道理。生:老师,我给刚才这位同学的发言补充一下,不管是白色的贝壳,还是黑色的贝壳,他们… 相似文献

小语第六册《沙漠里的船》是常识性课文。乍一看,只要让学生知道骆驼的外形特点及其作用就行了。但南京市长江路小学王兰老师认为,这是一篇对学生进行思维训练的好教材。下面介绍她的一些教学片断。王老师在教学第一自然段时,重点训练学生思维的条理性。她首先帮助学生明确概念,因为概念模糊,思维就不会有条理。教学开始,她要求学生找出这一段讲了骆驼身体的哪几个部分。学生说:“这一段讲了骆驼的身体高,脖子长。”这样回答,说明学生 相似文献

观摩窦桂梅老师上的《三打白骨精》,欣赏她上的《林冲棒打洪教头》,看她演绎《丑小鸭》,老师们在惊羡之余,感觉是一种享受,尤其是听她朗读。她曾说：“朗读不那么简单,它需要功力和感觉,要能读出文字里面的酸甜苦辣,这样的朗读才会更自然,更舒展。”可我们大部分老师都没有这等朗读技艺,该怎么办？笔者提几点拙见,期望能够从窦老师课文朗读艺术中受到一些启发。 相似文献

The experiment in which a candle is burned inside an inverted vessel partially immersed in water has a history of more than
2,200 years, but even nowadays it is common that students and teachers relate the change in volume of the enclosed air to
its oxygen content. Contrary to what many people think, Lavoisier concluded that any change in volume in this experiment is
negligible; moreover, the explanation relating oxygen consumption in the air with its change in volume is known to be wrong.
In this work we briefly review the history behind the candle experiment and its relationship with some typical erroneous explanations.
One of the key factors behind Lavoisier’s success was the use of experiments carefully designed to test different hypotheses.
Following these steps, we performed several closed volume experiments where the candle wick was replaced by a capillary stainless
steel cylinder supported and heated by a nichrome filament connected to an external power supply. Our recorded experiments
are displayed as web pages, designed with the purpose that the reader can easily visualize and analyze modern versions of
Lavoisier’s experiments. These experiments clearly show an initial phase of complete combustion, followed by a phase of incomplete
combustion with elemental carbon or soot rising to the top of the vessel, and a final phase where the hot artificial wick
only evaporates a white steam of wax that cannot ignite because no oxygen is left in the closed atmosphere. After either a
complete or incomplete combustion of the oxygen, our experiments show that the final gas volume is nearly equal to the initial
air volume. 相似文献

从前,有一句话,叫做"吃得苦中苦,方为人上人".这句话被认为动机不纯,怎么可以做"人上人"呢?其实,对于"人上人"可以作不同的理解,一种理解是"骑在人民头上,作威作福",这种"人上人"当然不好;但也可以解释为比别人做更多的贡献,吃更多的苦,经过更多的挫折与困难而比一般人更成熟、更坚强,更知道怎么做人.实际上,对这句话应是作后一种理解的,因为这种"人上人"是与"苦中苦"联系在一起的. 相似文献

The concept of metacognition refers to one’s knowledge and control of one’s own cognitive system. However, despite being widely
used, this concept is confusing because of several reasons. First, sometimes it is not at all clear what is cognitive and
what is metacognitive. Second, researchers often use the same term, namely, “metacognition” even when they refer to very different
aspects of this complex concept. Alternatively, researchers may use different terms to indicate the same metacognitive elements.
Another foggy matter is the interrelationships among the various components of metacognition discussed in the literature.
This conceptual confusion regarding the concept of metacognition and its sub-components calls for in-depth theoretical and
conceptual clarifications. The goal of this article is to portray a detailed example of a conceptual analysis of meta-strategic
knowledge (MSK) which is one specific component of metacognition. This specific example is used to draw a general model for
conceptual analyses of additional metacognitive components. The approach suggested here is to begin with a clear definition
of the target sub component of metacognition, followed by a systematic examination of this sub component according to several
dimensions that are relevant to metacognition in general and to that sub component in particular. The examination should include
an analysis of how the details of the definition of the target sub-component refer to: (a) general theoretical metacognitive
issues raised by prominent scholars; (b) definitions formulated and issues raised by other researchers who have investigated
the same (or a similar) sub-component and, (c) empirical findings pertaining to that sub-component. Finally, it should be
noted that since metacognition is a relational rather than a definite concept it is important to situate the context within
which the conceptual analysis takes place. 相似文献
