从2005年高考生物实验题的实际情况来看，教材知识点是实验题命题的基点，教材实验拓展是实验题取材的重点，借助实验方法创设新情境，侧重考查学生对实验进行探究和分析的能力成为命题趋向。其中设计型实验题与探索性实验更是热点，运用学过的知识、实验方法和步骤，突破已学实验的局限，自行设计新的实验方案，此类实验试题全面考查实验基本知识， 相似文献

学生操作实验体会远安县茅坪场镇横店小学汪宗炎（４４４２００）学生操作实验，并不是放任学生胡乱实验。在实验的过程中，教师要进行指导，为学生提供实验材料，要求学生按规定的实验目的，自己设计方案，组装实验材料，观察实验现象，做好实验记录，分析实验结果。在整... 相似文献

化学是一门以实验为基础的学科，实验推动着化学的发展，实验在培养学生创新意识和创造能力方面有着独特的作用。但中学化学教材中的常规实验大多是验证性实验，已经沿用多年，虽有个别实验进行过调整和改进，但总体上仍未摆脱常规实验设计思想的束缚，以至于有的实验忽视了环境保护，有的实验成功率低，有的实验现象不明显。所以，化学实验改革迫在眉睫，而针对常规实验的不足，改进传统实验形式，创新实验设计，是目前化学实验改革的当务之急。 相似文献

众所周知，物理学是一门以实验为基础的学科，实验在其中处于十分重要的位置。目前，高考理科综合测试的目标要求考生能掌握教学大纲中规定的实验，包括实验目的、实验原理和实验步骤，会控制实验条件和会使用实验仪器；会观察和分析实验现象，解释实验结果(数据)并得出实验结论；能够根据要求设计简单的实验方案。简而言之，理科综合测试对设计和完成实验的能力目标分为两条， 相似文献

教学中引导学生进行反思，对进一步理解实验、深化实验、完善实验起着重要的作用。通过反思可总结实验规律，优化实验方案，创新实验没计，揭示实验本质，增强实验效果。那么，物理实验之后应反思些什么呢？ 相似文献

物理学是一门实验科学，一个合格的高中生应该具备良好的实验素质，而设计实验的能力是学生实验素质的综合反映，是学生的创造力、观察力、想象力以及应用知识解决问题能力的具体体现，根据实验目的和要求理解实验原理，正确选用仪器和器材，设计实验装置，编写正确的实验步骤，设计合理的实验表格以及对实验进行改进等都属于设计实验能力的范畴，为了有效地培养学生设计实验的能力，我认为应从以下三方面着手。 相似文献

实验是物理知识的重要源泉，也是物理学的基本研究方法，它对物理学的发展始终起着决定性的作用。在中学物理教学中，实验占有很重要的地位。因此，即或是实验设备较差的乡村中学的物理教师，也应想方设法进行物理实验，力争发挥实验在教学中的作用。物理教学实验按其组织形式和师生活动的特点可分为演示实验、学生实验和课外实验。对演示实验和学生实验，教师一般都很重视，不论对实验的设计，实验的操作，还是实验结果的分析，实验的指导等方面都很认真。但对课外实验问。实验、小制作）重视程度稍差，甚至被忽视。其实，小实验对物理教学… 相似文献

传统的以知识为中心的化学实验教学，实验往往是理论知识的“附属品”，无论是教师的演示实验还是学生实验，基本上都是验证性实验。学生在做实验时，只要按部就班地遵照课文中描述的实验步骤或是模仿教师的实验操作验证出已有的实验结论就算完成实验任务。他们既不会对实验现象提出质疑，也不敢对实验方案进行“异想天开”，以至于不少学生还养成了“做实验不如看实验，看实验不如背实验”的思维定势。 相似文献

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? 相似文献

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. 相似文献

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. 相似文献

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. 相似文献

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. 相似文献
