五、【课后反思】（教师寄语：Never do things by halves）
篇2 七年级上册地理课件说课稿
根据新课程标准的要求和学生的知识基础及认知能力我确定本节课的教学目标为以下三个方面：一是知识技能目标：知道印度的人口数量及人口问题;掌握印度地形和气候的特点及其对农业生产的影响;了解印度的工业概况。
二是过程方法目标：通过对印度的地理位置、地形和气候的学习，初步学会对一个国家的自然地理条件进行综合评价。
三是情感态度与价值观目标：从印度人口问题的严重性，进一步懂得人类必须自觉控制人口的重要性和必要性，树立正确的人口观。
依据新课程标准的要求和教材内容我确定本节课的重点内容：
一是印度水旱灾害的原因;
二是印度的农作物分布及其与地形气候的关系。
本节教材的难点是印度水旱灾害的原因分析，我确定这个难点的依据一是造成水旱灾害的原因涉及地理位置、地形、气候等多方面的因素，本身就是很复杂的问题。二是学生综合分析问题的能力还较差，难以将诸多的地理因素综合在一起，得出结论。
重点和难点已经确定，怎样处理教材就水到渠成了。本节课我将用两个课时讲解，详讲的内容是印度的人口问题、印度水旱灾害的原因。
那么，如何把握重点，突破难点，实现本节课的教学目标呢?那就要采用适宜的教学方法和教学手段。教法的选择要根据教无定法、贵在得法和以学为法的原则，这是新课程"以人为本"的教育思想的体现。
在本节课教学活动中，我采用讲练结合的启发引导式教学方法，合作讨论法和利用图形展示直观教学法。我采用这种教法的依据有三：一是现代教学研究证实真正的理解是学习者对知识的主动再构建。知识再构建依靠提出问题，引导推测，鼓励大胆猜测与想象，解决问题，主动建构知识体系。二是根据"二期课改"精神，教师转变课堂角色，由知识的传播者转变为学生主动学习活动的指导者、合作者与促进者。三是把抽象的地理事物通过直观的图形图表表现出来，变难为易，学生更容易理解。
在教学手段上，充分发挥多媒体课件的作用，把多媒体信息如文字、图像、声音等有机集成并显示在屏幕上，以强化教学的直观性，帮助学生理解记忆，提高教学课堂效率。
教学矛盾的主要方面是学生的学。教是手段，学是中心，会学才是目的。教师在教学中必须"授之于渔",培养学生独立获取知识的能力，以实现新课程理念终生学习的目标。基于以上考虑，本节课我主要从以下几个方面渗透学法：
首先，在生理上，青少年好动，注意力易分散，爱表现自己，抓住这一生理特点，创造多种机会和条件，让学生参与进来，提出自己解决问题的办法，发挥学生学习的主动性，使学生学会合作学习。这样可使学生在探究性学习中，掌握比较、分析综合，归纳总结等科学的学习方法。
其次，有效利用互联网和图书馆知识量丰富、资源共享这些优点，我鼓励学生从互联网和图书馆中获取知识，向学生介绍一些网站，搜索引擎和关键词，教给学生独立获取知识的方法。
本节课教学总的思路是以知识结构为线索，激发学生的学习动机，通过师生问答，把教师的认知结构转化为学生的认知结构。整个教学过程我将围绕"印度的人口概况，印度自然环境，农业和工业的状况"这一主线来组织教学。通过构建四大问题情景、两次合作讨论来完成。
激趣设悬导入新课，采用多种直观手段，有利于使学生的注意力始终集中在课堂上。本节课在导入过程中，首先放映幻灯片(泰姬陵、印度舞蹈、街上踱步的牛、恒河中沐浴的教徒、新德里城市风光等)，配以解说：这是一个历史悠久的文明古国，是佛教的发源地，有着光辉灿烂的古代文明，泰姬陵、歌舞享誉世界。这是一个视牛为神明的国家，大街上牛可以自由漫步;这也是一个人口大国，人口已超过10亿，仅次于中国……猜一猜"这是哪一国家?"使用直观的手段导入新课，可以激发学生的学习兴趣。
揭晓答案—-印度，转入新课。教材第一部分内容是印度的位置范围及地形，我将结合多媒体课件，围绕印度地图进行讲解，通过读图让学生回答下列问题：印度在世界中处于什么位置印度的临国主要有哪些?它们在什么位置?(巴基斯坦、中国、尼泊尔、孟加拉国、缅甸、以及隔(ge)海相望的国家斯里兰卡)找出喜马拉雅山、恒河平原、德干高原，说说印度地形分布的特点。这样处理可使学生对印度有一个初步的认识，还可以突出地理学科的特点，即从地图中获取知识，在地图中消化理解知识。
印度人口这一部分内容我采用结合图表，以问答的形式解决，这样可以训练学生搜集整理分析地理信息的能力。
从1951年到20XX年印度人口大约增加了多少亿读图分析印度人口每隔10年的增长速度学生阅读"印度的人口政策"和数据表，分组讨论人口过度增长会给印度带来的影响，让学生合作讨论，我再做归纳总结。
印度除了人口压力外，还面临着水旱灾害威胁，我用多媒体展示印度的水旱灾害图片，让学生从感性上认识自然灾害的无情，激发同情心，让学生学会辨证地看待自然。
印度水旱灾害给人民的生命财产造成了巨大的损失，那水旱灾害产生的原因是什么呢?引出下一个难点印度水旱灾害的原因分析。
这部分内容我让学生读图合作讨论回答下列问题：对照亚洲气候分布图，看看印度以哪种气候类型为主?以图为例分析该气候类型的特点。比较分析1月、7月盛行风向有什么不同?西南季风对印度的降水有何影响?完成38页表，以说明印度的水旱灾害与西南风变化的关系。这样知识点明确，条理清晰，深入浅出突破了难点。最后我做归纳总结的方法解决，这样既可训练学生发散思维，又能训练学生综合分析问题的能力。
自给有余的粮食生产这部分内容包括两个方面：1、"绿色革命"2、印度农作物的分布及其影响因素，其中"绿色革命"是次重点，而且容易理解，我采取给学生提供材料让学生自学的方式解决，培养学生的自学能力。印度农作物的分布及其影响因素这部分内容是教材的重点也是难点，我采用结合动画对比分析的方法解决我先用动画向学生展示印度的农作物分布及印度的降水量分布图。让学生自己观察得出结论，我再用表格对比的方式进行归纳总结。这样可使知识更加系统化，培养了学生逻辑推理能力。
在教材中，印度工业和印度农业在结构上有相似之处，这部分内容我采用引导学生自学的方式解决，这样有利于培养学生自学能力和搜集整理分析地理信息的能力，使学生由学会变为会学。
本节课，我设计了两类练习题，一是填空题，考查学生的记忆能力和对基础知识的掌握程度。二是综合题，考查学生读图、用图、综合分析问题的能力。这两类练习题，起到了巩固本节内容，考查学生掌握情况，反馈教学效果的功能。这些练习题确定的原则是：遵守教学大纲，突出思想性、基础性和教学重点、难点;训练量适中。
对于课后总结这一环节，我的理解是，总结不应该仅仅为知识的简单罗列，而应该充分发挥学生的主体作用。所以我设计了以下3个问题：通过本节课的学习，你学了什么你的体验是什么你掌握了什么?因而其总的设计意图是回顾知识，强化记忆。

篇6 七年级上册语文《春》教学课件
教学目标
①反复朗读，感知内容，体会美
②理清思路，揣摩词语，品味语言。
③联系实际，广泛阅读，开阔视野。
教学重点
反复朗读，感知内容，揣摩词语，品味语言。
课前准备
古今中外写春的作品很多，课前布置学生去搜集关于“春”的诗文，以开阔视野，拓展思路，增加知识积累。
教学内容
整体感知课文内容，理清文章思路。
教学设计：
一、整体感悟
①导入新课 (大屏幕出示春的六幅画面，打乱次序。)
屏幕上这一幅幅的画面，让我们在美丽的春光中陶醉，为那洋溢的诗情所感染，为那盎然的生机所激动。春，会在我们的心灵中幻化出一派充满诗情画意的美好景象。春天是美丽的，当我们带着对美好景物的热爱、赞美之情的时候，我们思想的河流会跳动出充满对生命热爱的美妙无比的浪花;我们感情的波澜也会在秀美迤逦的景色的云海中起伏飘荡。朱自清先生在散文《春》中所描绘的景物就充盈着跃动的活力和生命的灵气。今天，我们一起学习《春》，了解感知作者是怎样用心灵去感受春天的景物、将自己的情感倾注其中的。
(出示目标，板书课题。)
②感知内容
a.认知性朗读，读准字音，疏通字词，朗读中教师正音，学生圈点。
b.感知性朗读，朗读时记住课文内容，并将大屏幕上的画面按课文内容的顺序重新排列，从而理清文中的思路。
勾勒轮廓：(板书或投影)
春草图——草报春
春花图——花争春
盼春——绘春 春风图——风唱春——颂春
春雨图——雨润春
迎春图——人迎春
二、研读与赏析
朱自清先生将自己的感情融于景物中，在他的笔下，所有的景物——那小草，那春花，无不充盈着跃动的活力和生命的灵气，以至于也撩拨起我们的喜爱之情。
①潜心精读：
[问题组]
a.你喜欢朱自清先生描绘的哪一幅图画?
b.说说你为什么喜欢?体会作者的思想感情。(赏析好词好句)
c、读一读，读出情。
★ 组织学生自主、合作、探究学习：学生自由朗读、思考、体味后，四人小组讨论交流，每组推举一人全班讨论发言。全班讨论回答，明确上述问题。
“说说你为什么喜欢”一题，是让学生自己去读书，去感悟，可以是一个词用得好，可以是一句话写得形象、生动。
[明确]
◆小草偷偷地从土里钻出来——“钻”字用得好，“钻”表现了生命力顽强，写出了春草而出的挤劲。“偷偷地”写出了不经意间，春草已悄然而出的情景。这样写赋予小草以感情和意识，富有情趣，惹人喜爱。“偷偷地”要轻读，将“钻”换成“长”或“蹿”就平淡了，既没有了那种顽强的生命力，语言也不生动形象了。
◆“嫩嫩的，绿绿的”本该在“小草”的前面，为什么放在句末?——放在句末，单独从句子中拿出来，主要是为了强调，突出了小草嫩绿的特点，同时使句子生动活泼，富有生气。读时第一个字重读，后两字要轻。将“嫩嫩的，绿绿的”放回原来应在的位置，作比较朗读，体味其不同的效果。
◆“吹面不寒杨柳风”，不错的，像母亲的手抚摸着你——抚摸是一种温暖、亲切、慈爱、是一种幸福，并含有深情的感觉。
◆课文最后三段的三个比喻句，总写春天的新、美、力。春天是新的，她有旺盛的生命力;春天是美的，她活泼生动;春天是健壮的，她充满了力量。
◆“盼望着，盼望着”——期待春天的心情多么殷切。东风来了——报告春天的消息。春天的脚步近了——赋予春以人的动作，表现了作者殷切而又喜悦的心情。
◆春风是无形的，是难以描绘的。作者娴熟地从触觉、听觉、嗅觉的角度，把无形、无味、五色的春风写得有声有色，有情有感。
学生还可以找出多处去理解、品味、鉴赏、朗读。
[教师小结]
在理清了文章的思路之后，同学们针对自己喜爱的图画，抓住重点的字词句，仔细品味、赏析，真正体味到了《春》一文准确生动、朴实鲜活、异常精美的语言。文章开头写盼春，以“脚步近了”始，以“领着我们上前去”终，起于拟人，终于拟人，体现了结构的美妙和严谨。作者用心灵去感受春天的景物，将自己的情感倾注其中，表现出作者向往春天、热爱生活、充满希望的真情实感，是不可多得的美文。让我们追随着作者的思路，感受作者的感情脉搏，调集起我们对春天的赞美之情去朗读全文。
②声情并茂地朗读，体会作品的意境、风格，读出对春天的由衷的赞美，可以小组展开朗读竞赛，学生可以互评。看画面朗读，背诵。

一、创设情境、提出问题
某班举行知识竞赛，评分标准是：答对一题加1分，答错一题扣1分，不回答得0分；
每个队的基础分均为0分.两个队答题情况见书上第23页.
二、分析探索、问题解决
分组讨论扣的分怎样表示?
用前面学的数能表示吗？
数怎么不够用了？
引出课题.
讲授正数、负数、有理数的定义.
用负数表示比“0”低的数，如：－10，读作负10，表示比0低10分的数.启发学生再从生活中例举出用负数表示具有相反意义的数.
三、巩固练习
1、用正数或负数表示下列各题中的数量：
（1）如果火车向东开出400千米记作+400千米，那么火车向西开出4000千米，记作:
（2）球赛时，如果胜2局记作+2，那么-2表示:
（3）若-4万表示亏损4万元，那么盈余3万元记作:
（4）+150米表示高出海平面150米，低于海平面200米应记作:
分析：用正、负数可分别表示具有相反意义的量，通常高于海平面的高度用正数表示，低于海平面的高度用负数表示；
完全相反的两个方向，一个方向定为用正数表示，则另一个方向用负数表示；
如运进与运出，收入与支出，盈利与亏损，买进与卖出，胜与负等都是具有相反意义的量．
2、下面说法中正确的是（）.
a．“向东5米”与“向西10米”不是相反意义的量；
b．如果汽球上升25米记作+25米，那么-15米的意义就是下降-15米；
c．如果气温下降6℃记作-6℃，那么+8℃的意义就是零上8℃；
d．若将高1米设为标准0，高1.20米记作+0.20米，那么-0.05米所表示的高是0.95米．
三、小结回顾、纳入体系
学生交流回顾、讨论总结，教师补充如下：
概念：正数、负数、有理数.
分类：有理数的分类：两种分法.
应用：有理数可以用来表示具有相反意义的量.
