1、1/4 黄河是怎样变化的说课稿一、说教材黄河是怎样变化的是人教版小学语文第八册第三单元的一篇读课文，课文介绍了黄河变化的过程，变化的原因及其治理方案，告诫人们要保护大自然，保护环境，否则就会受到大自然的惩罚。课文先写了黄河给两岸人民带来的苦难，是一第多灾多难的禍河，但它又是中华中族的“摇篮”；拉着，从黄河含沙量的现状分析黄河变化的原因；最后写科学家设计了治理黄河的方案。这是一篇说明文，文章条理清楚，材料确凿，数据详实，字里行间包含着强烈的忧患意识和环保意识和环保意识，教材中选这篇课文的目的，一是引导学生学习把握课文的主要内容的方法，进一步提高略读能力；二是使学生从中受到启示，培养环保意识，激发

2、保护母亲河的责任感。综合课文的特点，针对学生实际，我将本课安排一课时教案，制订以下教案目标及教案重难点：（一）教案目标1、认识 8 个生字。2、朗读课文，把握课文主要内容，了解黄河发生变化的过程和原因，从中受到启示，增强环保意识。3、搜集有关黄河的资料，激发保护母亲河的社会责任感。（二）教案重难点了解黄河发生变化的原因，从中受到启示。二、说教法2/4 新课程的核心理念是：“一切为了孩子的发展”基于这一理念，我在教案本课时主要运用“导放结合，自学为主”的教案方法引导学生学习，让学生独立阅读文本，探究问题，感悟思想内容，突出学生的学习主体地位。三、说学法新课标说：“阅读是学生的个性化行为”肯定了阅

3、读中应以学生的自主阅读为教案活动的中心内容，由于本课是略读课文，更突出强调了学生的独立阅读，所以在教案中，我引导学生采用“独立阅读，自我检测”的学习方法进行学习活动，这样，学生在阅读实践中，锻炼了能力，发展了思维。四、说教案程序（一）导入新课，揭示课题一上课，我以歌词导入，然后让学生交流课前准备的有关赞美黄河的诗句，通过前人对黄河的赞美，引起学生对黄河的关注和思考：就是这样一条美丽的黄河发生了怎样的变化？为什么会发生这样的变化？提着揭示课题，学生读题后，引导学生质疑：读了课题，你想知道什么？培养学生善于发现问题，提出问题的能力，激发学生阅读的积极性和主动性。（二）初读课文，整体感知我在引导学生

4、第一次读文时，先向学生提出阅读要求，让学生有目的地读课文，接着眼于抽读生字新阅，最后概括课文的主要内容，这样，学生通过第一次读文，就能把生字新阅读准确，又能概括课文的主要内容。（三）再读课文，加深理解1、展示问题，引导学生带着问题独立阅读，小组交流重点问题组织全班交流，师生评价，朗读重点句段，借助课件，点拨理解难点，结合资料袋畅谈阅读感受和体会激发环保意识与保护母亲河的社会责任感。文档编码:CJ1R6T2P7N4 HT2N2I4H10G4 ZM7L10Q8M4O6文档编码:CJ1R6T2P7N4 HT2N2I4H10G4 ZM7L10Q8M4O6文档编码:CJ1R6T2P7N4 HT2N2I4

19、叙写的内容上看，文字浅显，易懂，但是黄河对于我们学校的孩子来说是非常陌生的，从没有亲眼看见过黄河那雄伟的气势，也从没有亲耳听到过那波涛澎湃的浪涛声，只有从电视或课本中了解一点点有关黄河的史料。基于此，在教案中教师不但要让枯燥、乏味的文字变成学生愿学、乐学的素材，而且要让学生了解它的历史和现状，唤起他们保护大自然、保护母亲河的爱心。在这篇课文的教案过程中，我觉得有以下不足，还须改进：1、整个课堂没有充分发挥学生的自主性，还是教师讲得太多了；2、整个课堂气氛不活跃，学生学习的没有调动起来；3、课堂活动时间安排不够合理，在理解课文时，留下的时间有点紧张，以至于学生的小组活动进展的不是很好，最后课件也

20、没有展示完整；4、课件准备不充分，应该下载个视频，让学生更近地了解黄河；5、没有进行板书。说课人：甘肃省和政县中庄学校张丰华文档编码:CJ1R6T2P7N4 HT2N2I4H10G4 ZM7L10Q8M4O6文档编码:CJ1R6T2P7N4 HT2N2I4H10G4 ZM7L10Q8M4O6文档编码:CJ1R6T2P7N4 HT2N2I4H10G4 ZM7L10Q8M4O6文档编码:CJ1R6T2P7N4 HT2N2I4H10G4 ZM7L10Q8M4O6文档编码:CJ1R6T2P7N4 HT2N2I4H10G4 ZM7L10Q8M4O6文档编码:CJ1R6T2P7N4 HT2N2I4H10G
