1、名师精编优秀教案黄河的治理公开课教案学校：广宁中学教师：黄雄健一、教学目标（1）知识目标掌握黄河的自然特征；了解黄河的三个奉献；理解凌汛和“地上河”的成因；知道如何根治黄河。（2）技能目标力求通过读图、分析，使学生运用地图的能力得到提高；通过分析下游“地上河”的成因，提高分析问题的能力。（3）情感态度与价值观目标通过黄河治理的今昔对比，培养爱国情感；通过黄河多沙的人为原因分析，加深学生的环境忧患意识，树立正确的人地观念；通过黄河利与弊共存的事实，增强辩证观，学会一分为二地看待问题。二、教学重点和难点重点：（1）黄河中游水土流失和下游“地上河”成因；（2）根治黄河的措施。难点：分析凌汛现象和下游

2、“地上河”成因。三、教学方法多媒体辅助教学，自主学习法四、教具准备多媒体课件教学过程：名师精编优秀教案新课导入:同学们都知道我国唐代诗人李白吧，他有句名诗：君不见，黄河之水天上来，奔流到海不复回。你们知道描写的是我国哪一条河流吗？没错，是黄河，被称之为我们中华民族的母亲河。那么黄河之水是否真的向李太白诗人说的那么神奇来源于天上？为什么被称之为母亲河呢？要想知道这些，那么就让我们一同我们今天的地理课堂:黄河的治理，去揭开她真正的面纱吧！首先，我们先走入了解黄河的第一站：黄河的概况。要求学生自主观察课本48 页黄河流域水系图，找出：1.黄河发源地和注入地分别是哪里？2.黄河流经的省级行政区有哪些？

3、3.黄河上中下游分界点以及各自属于哪个省区？4.黄河流经的主要地形区和流经的阶梯是哪些？5.黄河流经的干湿地区和气候区又有哪些？学生在指图讲解完黄河流经的省级行政区后，老师以 PPT的形式做总结并在课件上显示。黄河是我国的第二长河。思考：同学们我们把“长”能换成“大”不？“不能。”为什么？水量少。(承转)了解黄河的概况后，我们来看看被称之为我们的母亲河到底有哪些突出的贡献？现在，让我们走入黄河的第二站：黄河的奉献。播放课件图片，指导学生思考并回答。奉献之一：“发电”用水库大坝的图片来引导学生。奉献之二：“旅游”用壶口瀑布的图片来引导学生。奉献之三：“灌溉”用“塞上江南”的图片来引导学生。奉献之

4、四：“文明”用秦兵马俑的图片来引导学生。(承转)我们不难看出，黄河对中华民族有着不可磨灭的贡献，但黄河也曾经给中华民族带来沉痛的灾难。我们既要看到黄河的“功”，又要看到黄河的“过”。为什么母亲河也被人称之为“害人河”，带着这些疑问，我们进入黄河第三站：黄河的忧患。假设同学们都是“治黄专家”，那么请你给我们的母亲河把把脉，看看文档编码:CJ1V5O7W3H4 HK2G9W2P7Z2 ZJ9H4L6A8H4文档编码:CJ1V5O7W3H4 HK2G9W2P7Z2 ZJ9H4L6A8H4文档编码:CJ1V5O7W3H4 HK2G9W2P7Z2 ZJ9H4L6A8H4文档编码:CJ1V5O7W3H4

11、病？学生结合课本P50-51 页，思考和讨论黄河的症状，小组之间讨论，并由代表阐述。病症之一：上游，用荒漠化和凌汛图片来引导学生观察。学生代表解释凌汛现象。病症之二：中游，用疏松的黄土高原图、降水柱状图和浑浊的黄河水图片来引导学生观察。水土流失严重，学生解释原因。病症之三：下游，用地上河图片、凌汛图片、断流图片来引导学生观察。地上河形成的过程。学生总结病症，教师加以指导，并补充解释凌汛现象和地上河形成的示意图。教师播放动画演示地上河形成的过程，让学生加深印象。(承转)好了，现在既然病因找到，关键是要如何对症下药。下面我们来到第四站黄河的治理，这也是本节课的重点所在。根据前面我们对母亲河的诊断，

12、现在就请同学们以本小组的形式展开讨论，稍后我们将以小组代表来总结出治理母亲河的措施。忧患治理措施上游荒漠化、凌汛退耕还林还草、炸冰破冰中游水土流失植树造林下游地上河断流凌汛加固大堤、疏浚河道节约用水、保护水资源（承转）同学们，通过四站的学习，我们对母亲河有了比较全面的了解，最后，我们通过一段黄河的视频，来验证我们刚才所学的知识。请大家认真看。教师播放黄河视频。好了，最后通过几道习题来，巩固我们本节课的知识内容。1.李白诗句“黄河之水天上来，奔流到海不复回”中，“天上”指的是哪里？“海”指的又是哪里？文档编码:CJ1V5O7W3H4 HK2G9W2P7Z2 ZJ9H4L6A8H4文档编码:CJ1
