浅谈生物课堂教学中的研究性学习

研究性学习的主体是学生,要充分让学生发挥自主抉择、自主探索、自主实践,形成运用知识解决实际问题的能力.让研究性学习走进课堂,为学生提供研究程序和方法的指导,是开展研究性学习的保证.     

高中英语教学中实施研究性学习的研究

学生是研究性学习的主体,而研究性学习主要是培养学生不畏探索的精神,感受近于科学的探索历程。在高中英语的教学中怎样实施研究性学习呢?自概念起,阐述研究性学习的特点,简单概括在高中英语教学中实施研究性学习的方法,培养高中生对英语的运用能力,把英语教学和研究性学习有机地结合起来,从而提升学生的整体素质和学习能力。     

探讨中学数学教学中开展研究性学习的途径

在中学开展研究性学习,是中学课程改革中最重要的内容之一,随着研究性课程的不断深入,愈来愈显示出其强大的生命力.因此,如何培养学生开放意识,构建、探索开放题是开展好研究性学习的关键.同时,数学研究性学习是面向全体中学生的必修课.本文着重探讨了如何在数学课堂中开展研究性学习的途径.     

生物研究性学习探究——以秋水仙素的学习为例

信息时代需要创新人才,呼唤创新教育."研究性学习"也就应运而生了.研究性学习以学生发展为本,通过学生自主探索式学习,使个性潜能得以充分发展,其目的在于培养学生创新精神和实践能力.下面以秋水仙素为例谈谈研究性学习的开展思路.     

巧用物理方法测量圆周率π

一、前言 随着课程改革的深入,研究性学习已经走进了数学课堂,这是一种积极的学习方式.研究性学习是学生学习数学的有效方法,是在基础性、拓展性课程学习的基础上,进一步鼓励学生运用所学知识解决问题的学习活动,是以学生动手动脑主动探索实践和相互交流为主要学习方式的学习活动.开展研究性学习的目的是要改变学生以往的单纯地接受教师传授知识为主的学习方式,     

探讨数学研究性学习

数学研究性学习是学生数学学习的一个有机组成部分,是鼓励学生运用所学知识解决数学和现实问题的一种有意义的主动学习,是以学生动手、动脑、主动探索实践和相互交流为主要学习方式的学习研究活动. 数学研究性学习的特点主要体现在它的开放性、研究性和实践性.它的功能在于能营造一个使学生勇于探索和相互学习鼓励的良好氛围,给学生提供自主探索、合作学习、独 立获取知识的机会. 数学研究性学习的材料不仅仅是教师自己提供的,教师应鼓励学生通过思考、调查、查阅资料等方式概括出问题,甚至可以通过日常生活情景提出数学问题…     

研究性学习在化学教学中的实施

采取"问题启发"探究式研究性学习方法,指导学生主动探索获取化学知识,形成较强的实践能力.发挥教师在研究性学习中的主导作用,使研究性学习即是个体自主的学习行为,又是一个有序的探究过程.     

研究性学习在高中历史教学实践中的反思

研究性学习只是改变学生获取知识的方式,由过去被动接受变成自主探索,其目的并不是要求学生进行学术研究。研究性学习更多偏重对现有的规律性的结论推导过程的探究．以及富有个性化的学习方法的探索,目的是促进学生对历史知识的理解与基本分析能力的形成。     

谈职业学校开展研究性学习的目标定位

1.研究性学习应该姓"学"而不姓"研" 研究性学习是通过"研究"这种方式进行的学习活动.当前开展研究学习活动,存在一味追求"研究"而忽视这种活动的"学习"功能的倾向.这种倾向把"研究性学习"的方法局限于只注重沿袭获得科学结论需要遵循的程序和方法,学生的个性化探究方式会被封杀,学生的思辨、畅想、感悟等丰富多彩的探索之路被中断,从而削弱了研究性学习活动课程的价值.为此,必须摆脱"惟科学主义"倾向.     

对于研究性学习评价问题的思考

一、对研究性学习评价的理解 根据<普通高中"研究性学习"实施指南(试行)>的解释,研究性学习是学生在教师指导下,从自然、社会和生活中选择和确定专题进行研究,并在研究过程中主动地获取知识、应用知识、解决问题的学习活动.可见,研究性学习不再只是由专家预先规划的特定知识体系的载体,而是师生共同探索新知识的生成、发展的动态过程;其内容是开放的、实践的,研究过程是民主的、探究的.研究方案的确定、资源的开发利用、合作者的确定等均可由学生自主决定.这种学生真正"当家作主"的学习方式为学生最大限度地发展创新思维和实践能力提供了空间,这是研究性学习的显著特点.笔者认为,研究性学习的评价方法应符合研究性学习的上述特点.要特别注意遵循下列原则.

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.
