皮亚杰建构主义对素质教育的启示

建构论是皮亚杰发生认识论的核心,他提出的主客体相互作用的双向建构理论,对我国素质教育的推行,以及形成新的教育模式,都具有深刻的启发性。总体来说主要有以下几方面的启示:有效的教学过程应是教和学的有机统一;教师应鼓励学生积极主动地参与课堂活动;教育活动要打破学生已有的平衡状态,指导和帮助学生建立新的平衡;有效的教学应培养和促进学生的自我调节;有效的教学应充分重视活动的重要性。     

建构主义的教学理论及其启示

建构主义作为一种新的认知理论，其教学理论认为：知识是不确定的；知识的学习过程即知识的建构过程；学生是学习活动的主体，主动地建构知识；教师是学生建构知识的帮助者、促进者。这些观点对我国当前教学改革有诸多启发：把学生视为教学活动的主体；重视学生学习的经验背景；重视教学的社会性；重视学生创新能力的培养。     

学生学习数学概念的层次分析

杜宾斯基认为，学生学习数学概念要进行心理建构，建构过程要经历4个阶段：操作（Action）阶段；过程（Prosess）阶段；对象（Object）阶段；概型（Scheme）阶段。即，学生学习数学概念需要经历操作活动，理解过程，形成数学对象，最后建立概念的综合心理图示。为此教师在教学中应注意：树立建构主义教学观并精心设计学习活动；体现数学知识形成中的数学思维方法；数学对象的建构需经多次反复。     

抓住关联 在操作中建构——以“角的分类和画角”为例

新课标给一线学校带来了新的教育理念，也为一线课堂注入了新的活力。作为教学一线对新课标的积极呼应，教师应该在配套的新教材出来之前，积极探索新理念指引下原教材的有效使用。本文以“角的分类和画角”一课为例，分享抓住关联在操作中建构的实践经验：在分类中抓住角的大小关联，建构角的分类；在画角时抓住边的位置关联，带领学生感悟画角的方法；在探究变化角的活动里，抓住变与不变的关联，促进思维进阶。     

英语教师需要适应"以学生为中心"的教学模式

开放教育试点要求教师转变观念、改变教学方法和更新自身的知识结构，以全新的眼光接受新的教学理念，建构以学生为中心的教学模式。在此模式中，教师和学生的地位、作用与传统的教学模式相比已发生了很大的变化。英语教师如何适应“以学生为中心”的教学模式?应转变观念；应改变教学方法；应更新知识结构，以适应教学新要求。     

在有序的活动指导中实现有效数学教学

皮亚杰活动教学理论表明,数学经验的建构植根于活动;现代教育实践表明,数学素养的形成有赖于活动。有鉴于此,数学教学应重视有序地指导学生的活动：活动之前,要有明确的导向;活动之中,要有适切的点拨;活动之后,要有及时的提升,从而实现有效教学。     

快乐教育“五要素”

要素一：愉快合作的课堂教学。在教学中，通过师生情感的交流，使师生都感到愉快。教学过程是教与学的双边活动，是教师与学生、学生与学生的互动过程，课堂教学应体现教师与学生、学生与学生的合作。愉快合作的课堂教学主要体现在“三乐”之中：师生关系的和谐之乐；教师的善教之乐；学生的学习之乐。要素二：多彩自主的教育活动。教育活动是快乐教育体系的主要部分，必须适合孩子们的年龄特点，使他们喜闻乐见。教育活动多样化。如艺术节、读书活动、科技月活动；多种兴趣小组活动；专业队活动；注重开发儿童创造潜能的少先队活动。教育活…     

主体性教学中的活动性探析

活动的观点是主体性教学思想的重要组成部分。活动是人的主体性生成的前提和基础。活动是教学过程的途径，因为：教学过程是一种交往活动；教学过程是注重活动性体验，强调理性认识与非理性认识相统一的过程；学生只有通过积极主动的实践活动，作为外部经验的教学内容才能转化为内部经验，并形成新的、特定的认知结构。在主体性教学中贯彻活动性原则，必须做到：活动形式要灵活多样；要留给学生充足的自主活动的时间；要坚持教师的主导作用；要能促进学生在教学活动中有效交往。     

存在主义教育思想对我国课程改革的启示

虽然现代西方人本主义思潮的主要代表——存在主义的影响主要表现在哲学思想上，并没有提出系统的教育理论，但其对教育思想却产生着极大的冲击。尤其是存在主义对教育活动中的人有着独特的认识和见解。强调以人为本；强调自由选择；强调对话。这对当前我国正在进行的新课程改革具有较强的启示意义和作用：加强学校人文教育，培养人格健全的人；尊重学生的主体地位，重视学生的自主建构；突出教师的引导作用，维护教师的选择责任；建构对话式教学交往形式。     

建构主义环境下校外特色教育课程教学设计原则

运用建构主义学习理论指导校外特色教育课程教学设计是一种行之有效的途径，这种理论指导下的教学设计应坚持以下原则：不迷信知识，鼓励探索；以学习者为中心；重视教师的指导作用；重视学习环境的设计；以“有效的”“意义建构”为目的。

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.

The Reader Response Approach to Teaching of English Literature

During interview with English majors, it was found that a majority of students expressed disappointment with their experience of English literature classes. Students' dislike of learning English literature appears to be the major problem of teaching English literature in China. Reader response approach is a good way to solve this problem. In this paper, I explain the rationale behind the reader response approach, such as its origin, definition, features, assumptions, and strategies. Then I illustrate how reader response approach works as a teaching strategy by presenting several teaching models. At last I evaluate its usefuiness for teachers and present the advantages of reader response approach in Chinese context.
