关于初中数学问题意识培养的研究

问题是数学的灵魂,没有问题就不会有较高质量的思维．问题意识是思维的动力,是创新精神的基石,是学生探求问题并解决问题的保证．培养学生的数学问题意识是培养学生探索创新精神的起点．在初中数学教学中注重培养学生的问题意识,养成他们良好的学习习惯,具有积极的意义．     

在数学教学中培养学生问题意识的实践与思考

素质教育的重点是培养学生的创新意识,形成创新意识的关键是培养学生的问题意识．问题是数学的心脏,问题意识又是创新数学教学的源泉．培养学生的问题意谀是培养学生探索创新精神的起点,是造就创新人才的关键之一,是学生素质教育的重要组成部分．教师在教学过程中应注重培养学生的问题意识,让学生积极参与教育过程,亲历问题的提出和解决过程,     

高中学生物理问题意识的缺失与对策

物理是问题构成的世界,问题是物理的心脏．提出问题是物理学习的重要组成部分,更是物理创新的出发点．但在多年的高中物理教学实践中,笔者发现,学生随着年龄的增长,提出的问题越来越少,到高中阶段几乎没有问题．大部分学生学习物理是很被动的,基本是“上课记笔记,下课看笔记,作业照方抓药”．这样做的结果是：教师是辛勤的搬运工,把知识从教材机械地“移植”到学生的大脑;学生只进行重复性的思维,只会做些常规题,不会提问题,不善于提问题,碰到开放性的习题只能干瞪眼．学生问题意识的缺失使笔者越来越认识到,如果不注重培养学生的问题意识,无异于忽视学生创造性思维和创新能力的培养,抹杀学生的创新欲望和创造力．     

问题情境在中学数学课堂教学中的创设

常言道：兴趣是最好的老师,兴趣是学习的动力,问题是数学的心脏．兴趣是学生学习动机中最现实、最活跃的成分．正如爱因斯坦所说：“只有热爱,才是最好的老师,它远远超过责任感．”学生之所以对学习不感兴趣,主要是因为对知识缺乏需要．要培养学生的学习兴趣,必须使学生对新知识产生热情,这要在课堂教学上下工夫．而成功的课堂教学,应该从问题人手,就是要向学生不断提出新的问题,千方百计为学生创设问题情境．可见,培养学生的学习兴趣,     

生物教学“问题导学法”情境创设策略

“问题导学法”是指在教学过程中以学生对问题探究和研究为主的教学方法,通过教师系统地设计一些问题情境．启发和引导学生思考．激发学生学习热情．充分发挥学生的主体性,让其主动参与问题的解决过程。培养学生的问题意识,促进学生创新能力的发展。在“问题导学法”教学中,要解决的问题是如何创设问题情境,引导学生有效思考。     

小学数学教学中创设问题情境的策略探究

美国数学家哈尔莫斯曾经说过：“问题是数学的心脏。”提出一个问题比解决一个问题更重要．问题是思维发展的体现．是不断进步的动力源泉。因此．在小学数学教学中．教师要有目的、有意识地创设各种问题情境．激活学生的思维．激发学生的学习兴趣．为学生提供自主学习、合作交流的平台．使学生在获得基本的数学知识和技能的同时．提升学生的综合素质。     

浅谈培养初中学生数学问题意识的必要性

培养学生发现和探究问题的意识,都是初中数学教学中不可或缺的内容．也是提高学生数学思维能力的必要途径．正确认识和把握培养学生问题意识的积极意义,对于促进学生数学思维能力的提高是非常有用的．本文从培养学生问题意识有助于促进数学思维能力的提高、有利于激发学生的创造力、有利于数学的建构性学习三个方面阐述了培养学生问题意识的积极意义．     

谈小学语文教学中对学生“问题意识”的培养

什么是“问题意识”？“问题意识”是一种觉察问题、发现问题的敏感度和观察力,是一种提出问题、解决问题的技巧和能力。从训练思维的角度来说．提出问题的本身比解决问题更富有意义。语文教学中．能否提出问题．反映了学生在学习时是否愿意动脑．能否提出有价值的问题．反映了学生在学习上是否愿意动脑．善于提出问题．是学生能够主动学习的重要...     

浅谈学生解决问题能力的培养

爱因斯坦说：“提出一个问题往往比解决一个问题更重要．”因此当前课堂教学改革,首先要研究和培养学生的问题意识．在提出问题的基础上。培养学生运用数学知识解决实际问题的意识和能力．解决问题是教学的最终目的,也是学生学习的最终目的．本文就小学生问题意识的培养谈几点体会．     

让物理课堂提问走向有效

问题是学习之始．课堂提问一向是教师进行课堂教学的重要方法和常用手段。有效提问．一方面能及时了解学生对学习的掌握情况．而且能活跃课堂气氛,提高学生的注意力．激发学生探究问题的兴趣,促进学生积极思考．加强与学生思维和情感的交流,从而对教学活动产生促进作用：另一方面．能调动学生学习的自主性．弥补教师对学生知识了解的遗落．有效提问是构成有效教学的重要内容．

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.
