归纳或演绎方法的教学设计分析

在小学科学教学中,我们总会使用到归纳或演绎的方法进行教学,但是,许多教师对归纳或演绎方法的运用处于一个不清晰的状态,甚至一些教师没有意识到自己已经使用了归纳或者演绎的方法来进行科学教学。事实上,早在上世纪90年代就有学者和一线教师提出运用归纳和演绎的方法来进行科学教学,培养学生的推理能力和科学思维。本文以《花的结构》一课为例,分别进行了归纳方法的教学设计分析和演绎方法的教学设计分析,并提出了归纳和演绎方法的优缺点以及使用条件,希望能对此类问题的教学有一定的启发。     

利用认知冲突，进行有效阅读

《中国大百科全书.教育卷》对"阅读心理"作了这样的说明:"阅读是从写的或印的语言符号中取得意义的心理过程,阅读也是一种基本的智力技能,它是由一系列的过程和行为构成的总和。"就是说,在阅读时,感知、想象、联想、思维、记忆等心智因素,分析、综合、推理、判断、归纳、演绎等心智技     

也论严复的逻辑思想

严复是中国近代逻辑思想史上的第一人，为引进并普及西方逻辑学做了大量工作。他有重归纳轻演绎的倾向，但不是全归纳派。而他之所以重归纳轻演绎，是为了纠正传统思维方式的弊病。     

《红楼梦》中人物对话英译的言语行为分析

言语行为理论是语言语用研究中的重要理论,为实现有效的语言翻译提供了理论支撑。从言语行为理论的观点出发来对人的语言行为进行解读,将言语本身定义为某种行为的实施,如言内行为、言外行为和言后行为等。在不同的文化语境中,言语行为理论的使用策略也不尽相同,只有通过结合具体的语言情境、说话者的语气、内容等多种要素,才能确保语言语用力量的有效传递。本文重点以《红楼梦》中人物对话英译为出发点来进行讨论,从言语行为理论的角度来对《红楼梦》中人物对话英译进行研究,从而来提升翻译信息的对称性,实现原意的有效传递。     

先秦、两汉归纳逻辑思想举隅

归纳与演绎的逻辑方法,在人类思维进程中交互为用.文明高度发达的中国古代文献,如《墨辩》、《荀子》、《吕氏春秋》、《淮南子》、《论衡》等对归纳逻辑思想有中国式的理论论述.这些丰富的文化遗产,需要我们进一步发掘、整理,以期古为今用.     

续《归纳还是演绎》

拙作《归纳还是演绎》在《湖南教育》刊载之后,李健行及罗兴国同志曾提出不同意见。其中许多意见是正确的,读了很受教益。但有些看法则不敢苟同,特提出请教,并以之为《归纳还是演绎》的续文。李健行同志的《<归纳还是演绎>的商榷》,批评我的分析“不是从语言的实际出发,而是从逻辑学的概念出发”,并举出了三条理     

策略性知识传授与大学英语阅读教学

策略性知识,也称认知策略,是指人们头脑中所拥有的有关计策谋略、技术方法等方面的知识。如人们在研究问题时采用的研究方针、管理方法以及归纳、演绎、分析、对比、综合等思维方法均属于策略性知识。策略性思维和策略的有效使用将大大提高语言习得者的成功机率。

归纳和演绎的选择与联动

归纳和演绎的一些思维运作方式有归纳结论,归纳方法,归纳更强的结论,先演绎再彻底的归纳,转化式演绎等,归纳和演绎在解决特定问题时具有独特作用,归纳和演绎的思维方式相辅相成,相互独立也相互依存,需要灵活的选择、联动它们,才能充分有效地发挥其作用,不能因为偏好而一条道走到黑.     

“演绎”不可缺位

<正>演绎思维方式的运用,可以让我们看到教学过程促使学生知行合一的操作范例。一、规范离开演绎难以落地归纳和演绎是认识过程两个既相互对立又相互依存的思维方法,离开归纳的演绎或离开演绎的归纳都是不可取的。综观思想品德课堂教学,笔者发现多数教师对归纳比较青睐,重视创设丰富的教学情境,让学生从情境材料中概括结论,然后记住结论并落实

漏洞百出的教育

Many college freshmen arrive woefully unprepared to do college work, and as disadvantaged populations continue to grow, the share of the American work force that has made it through college is expected to plummet. Many experts blame that educational failure not just on high schools but also on colleges. School & College, a special report by The Chronicle, looks at efforts to fix the system. What reforms would better prepare students for college? What should schools and colleges be doing differently? How should state and federal officials help?     

只要努力,不要后悔

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.     

浅谈移民问题

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.     

Sister Carrie, an Adherent of Desires

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.

胡主席在印度,我却在中国

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.
