运用“探究日志”评价中学生的科学探究能力

本文分析了运用探究日志来评价中学生的科学探究能力的过程,即首先要让学生参与到具体真实的科学探究活动中,并记录探究日志,然后根据编制的探究日志的评分标准,评价．出学生的科学探究能力。最后,探讨了运用这种评价方法时应注意的几个问题。     

中学生科学探究能力评价的现状与分析

通过对贵州省中学理科教师的问卷调查和访谈,可以看出,中学理科教师对评价科学探究能力的重要性认识统一,但评价意识不强,对如何评价学生探究能力把握不准,对用纸笔考试作为评价科学探究能力的唯一方式的现状不满意.认为课程标准对评价学生科学探究能力缺乏指导性,纸笔考试与实施的探究教学有差距,教师对考查或评价学生科学探究能力缺乏准备,课堂评价结果没有进入学生的评价体系是评价探究能力困难的原因.因此,推出与科学探究能力目标相匹配的可操作的评价标准,将表现性评价嵌入在科学探究的教学中,采取多渠道、多方式培训模式,提高教师评价能力是当务之急.     

中学生科学探究能力评价量表初探

本文运用PTA量表法即"基本要素特征分析法"对学生物理科学探究活动及能力进行了要素分析,并结合学生科学探究活动的实际特点,制定了科学探究能力的评价量表,为评价学生科学探究能力提供了一个参照标准.     

科学探究能力评价的适切性研究

采用引导性和开放性探究任务,评价1200名初三学生的科学探究能力,以研究在两类任务情境中科学探究能力评价的差异及适切性。研究发现,引导性探究任务没有构成一个产生式系统,它适合于评价初级的离散科学探究能力;开放性探究任务构成一个复杂的产生式系统,它适合于评价高级的完整科学探究能力。这些发现表明,在科学探究能力评价中,开放程度不同的探究任务有各自的适用情况不能相互替代。     

生物实验课中学生探究能力评价模式的构建

培养学生的探究能力是基础教育阶段生物课程的重要目标之一。探究能力的评价必须贯彻执行我国教育行政部门关于教育评价的指导思想，即“以评促改、以评促建，评建结合，重在建设”，必须有利于实施素质教育，有利于学生的主动发展。因此，生物实验课教学中探究能力评价模式的构建及评价操作程序的实施将成为一个关键的问题。

基于现场观察的科学探究能力的评价研究

本研究构建了一套现场观察评价体系,并以178名初三学生为测评对象,研究学生在动手探究中的表现特点。结果发现,学生在动手探究中的表现与探究任务的情境以及学生的知识、经验背景有关,这表明了科学探究能力不完全是一般性的认知能力,而是与情境相关或背景相关的复杂认知能力。     

注重科学探究教学 培养科学探究能力

开展科学探究教学，培养学生的科学探究能力和科学精神是新课程的核心理念之一。物理新课程标准中把“科学探究”定位为学生必须掌握的科学内容，并在新教材的编写中进行了合理的安排，充分凸显了当前物理教学中开展科学探究教学的重要性。科学探究是一种创造性活动，是探索物理规律的重要科学方法，科学探究能力是综合性的能力，科学探究能力的提高不是一蹴而就的，而是需要在平时进行一点一滴培养的。因此，物理教学中不仅要注意渗透科学探究的思想和方法，更要注重和加强科学探究教学，通过精心创设探究情境，重视探究过程的实施，充分发挥评价的激励功能，达到激发学生探究兴趣、提高学生科学探究能力、培育学生科学探究精神的目的。

论高中物理教学中学生科学探究能力的培养

高中物理是一门内容丰富、理论与实验相结合的学科。因此,高中物理教师在注重培养学生理论基础的同时,还要培养学生进行科学探究的能力。本文包含对科学探究能力内涵的论述、对当下高中物理教学模式缺陷的分析以及对高中物理课程应如何有效培养学生的科学探究能力的浅谈,希望通过本文的思考为我国教育培养高水平的科研人才提供一定的参考。

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.
