对儿童来说，数学究竟是什么？我们究竟应该怎样来组织儿童的数学学习？长期以来，我们总是将儿童的数学学习当作是认符号、记公式、背定义、练计算，做习题的一种过程，而并不关注儿童在生活中发现了什么？对什么感兴趣？从最根本的价值追求来看，小学数学教育的最基本任何应当是发展儿童的数学素养，好奇，好探究永远是儿童主动学习的内在动力，而数学应儿童的生活之中，因此，对儿童来说，学数学就应该是一个“做数学”的过程，显见，儿童产历数学的发现，探究与问题解决过程的体验是小学数学教学的基本目标之一。 相似文献

数学教育的价值是什么?小学数学教育的目标是什么?或者说,对儿童来说,什么是数学?怎样才叫懂数学?当我们将小学数学教育真正回归到儿童的发展历程中进行思考的时候,我们才有可能真正发现,我们的小学数学教研有必要认真地全面地做一个反思了。或许正是这种反思,有可能使我们对数学、对数学教育有一个认识上的飞跃。 相似文献

《数学课程标准》(实验稿)指出:"有效的数学学习活动不能单纯地依赖模仿与记忆,动手实践、自主探索与合作交流是学生学习数学的重要方式."倡导探究学习,引导学生经历知识的形成过程,是当前小学数学教学改革的重要内容.苏霍姆林斯基说过:"在人的心灵深处,都有一种根深蒂固的需要,这就是希望自己是一个发现者、研究者、探索者,而在儿童的精神世界中这种需要特别强烈."可见,儿童天生就具有强烈的好奇心和旺盛的探索精神,好动、好表现、好创造是他们的天性.因此,小学生的数学学习不应只是被动地接受知识,通过反复练习强化储存知识的过程,而应是利用已有知识主动建构新知的过程,应该具有探索性和思考性.在数学教学中,要让学生经过探索,不仅知其然,而且知其所以然,帮助学生获得丰富的数学活动经验,提高学生的探究、发现和创新能力.那么,在小学数学教学中如何提高学生的探究能力呢?下面谈谈自己的几点体会. 相似文献

探究学习是当前小学数学教学的重要内容.每个孩子都希望自己是一个发现者、研究者、探索者,而在儿童的精神世界中这种需要特别强烈.儿童这种与生俱来的探索欲望,是小学数学教学中实施探究性学习的重要基础.那么,在小学数学教学中如何有效地开展探究性学习呢?现从以下三个方面谈谈自己的粗浅认识. 相似文献

小学数学学习应该是儿童自己的数学活动,让儿童在动手操作中探究、发现。真正具有探究性质的操作,应是儿童自己的活动,操作目的是为了支持数学思考,操作以儿童自己的反思为基础。转变学生的学习方式,就要转变学生在课堂学习中的参与方式,关注学生学习过程的亲历与体验。 相似文献

数学教育的真谛究竟是什么,尽管有些文章从不同侧面给予了回答,但都没有切中要害,只在问题表面转圈.经过多年实践,我们发现"度"与"悟"才是数学教与学的关键所在.本文着重阐释为什么要在小学数学课堂教学中培养学生的悟性、怎样培养学生的悟性.数学课堂教学在教与学上究竟应怎样把握好度?作者围绕五个方面并结合相关案例进行叙述,即扶放有度、开合有度、动静有度、进退有度、学练有度.在把握度的基础上,引导儿童领悟数学思想方法,最终达到融会贯通的境界. 相似文献

随着课程改革的不断深入,在小学数学课堂上,涌现出不少的"时尚元素"。在教学过程中,教师采用多种教学形式,如充分利用多媒体等教学设施、学生自主探究、合作学习等,使课堂教学变得热闹非凡。但数学课堂的效率如何呢?值得每一位数学教师深思。我们不妨截取几个镜头来看看,眼下时尚的数学课堂是究竟什么模样的。 相似文献

There are numbers of crossroads on our long and unpredictable life journey where we totally have no idea about which direction to choose. No matter what our decision is, we should not turn back, but face the music and go ahead instead. I am this kind of girl who always does try without regretting, one example is how I dealt with my love. 相似文献

Migration occurs behind a variety of reasons and has a great effect on the whole world. People may migrate in order to improve their economic situation, or in order to escape civil strife, persecution, and environmental disasters. The impact of migration is complex, bringing both benefits anddisadvantages. This paper briefly talks about the causes of migration, the allocation of benefits, and the ways in which individual countries and the international community deal with this important subject. 相似文献

Sister Carrie is one of the most controversial characters in American literature.Thought as a "fallen woman" firstly,she was defined as a "new woman" by some critics later. However, by digging into the motivaton behind the whole process of Carrie's "success", the relationship between Carrie and her creator (the author), the social conditions of then American, it can be found that Carrie has never been free-standing on her thought and she has never found her real-sdf even after becoming a famous actress. In a society dominated by mass consumerism Carrie is only an adherent of her own desires. She also is a representative of all those country girls flooded into cities, a symbol and a sacrifice of the urbanization of America in a time countryside was overcome by cities. 相似文献

Today, Sunday morning, I sit thinking and typing at my computer. My thoughts are in my homeland, India and my body is in China. The body is here and mind there for a good reason. Mr. Hu is president and I am resident and both are in each other's countries (what a difference the absence of one small letter makes!). Mr. Hu will return in a few days and I will stay on longer. 相似文献
