数学理解障碍是数学学习中不容忽视的一种障碍．从数学认知、教育心理学等层面来讲，中学生的数学理解障碍有认知型障碍，表象型障碍，联系型障碍，语言型障碍；克服这些障碍相应的教学对策有：帮助学生生成正确的数学表象；利用实物、模型等，增强学生对知识的感性认识；利用多媒体进行辅助教学；注重数学交流；加强学生对数学知识的自主探究与实际应用等来加深理解。 相似文献

数学是由大量概念和命题构成的符号体系，由于符号的抽象性。增加了学生学习的困难。如果回避这一问题，而对符号的意义和作用缺乏理解，则会对以后的学习构成更大的障碍。所以，注重数学符号的阅读与理解，对培养学生良好的数学意识具有重要作用。 相似文献

数学学习很容易出现理解障碍。由于数学学科逻辑性、推理性较强,前后知识联系紧密,一旦出现理解障碍,所学知识就会发生断层,影响后面知识的学习。基于此,笔者在探讨数学理解与数学理解障碍的涵义后,分析了数学理解障碍的生成机制,介绍了信息技术及其在教学中的作用,并提出了在信息技术环境下排除数学理解障碍的相关对策和建议,以帮助学生更好地学习。 相似文献

在教学中,我们经常听见教师抱怨学生的基础差,缺乏对知识运用的灵活性和综合能力,做过的问题一做还错．笔者认为一个重要的原因在于学生对所学的知识、方法没有理解到位．数学学习的关键在于理解,数学教学应该是数学理解的教学．而在实际教学中,教师不注重学生的数学理解学习的情况普遍存在,学生学习的主要方式是：听讲、模仿和机械训练．学生一时记住了概念、公式、定理,但不知其来龙去脉,时间长了, 相似文献

理解具有重要的教育价值。理解是数学课程标准的要求。理解是学生学习数学的基础．对学生增强学习数学的信心,掌握数学的基本思想和方法,提高数学学习的能力都有重要意义。数学教学理解策略的实施,要善于借助学生已有的知识储备,充分调动学生的内外部活动,积极组织学生进行讨论和交流,注意学生理解的多样化,提高学生的元认知水平。 相似文献

一、问题提出
数学理解在数学学习中占有重要的地位，它包括对陈述性知识的理解，对程序性知识的理解和对过程性知识的理解等三个方面。形成学生数学学习障碍有很多种原因，其中数学理解障碍就是一个很重要的原因。本文从西安市43中初一年级8个班共400名学生中选取被试。 相似文献

应用题的一个明碌特征是字叙述多，生活常识多，科学术语多，相关的制约因素多，这对于学生的阅读理解能力有较高要求．许多初中生阅读应用题后往往对题意理解不透，给解题造成很大障碍．因此，有必要对当前初中生阅读数学应用题时出现的理解障碍进行调查研究．本试图通过研究，分析出影响初中生对数学应用题进行正确地阅读理解的因素，进而给出帮助学生克服理解障碍，提高对应用题的阅读理解能力的教学对策． 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
