人教版高中英语必修5Great scientists说课稿4篇
通过写文章梗概，培养学生综合运用语言的能力，学习用恰当的英语描述科学家的故事。这是本课的教学难点。教师可以使用完形填空的方式来帮助学生整理语篇，从而来降低难度。本课的教学重点的突破方法是：在阅读前，让学生初步了解得出科学观点所需要的基本程序，从而轻松而自然地导入文章的阅读；在阅读过程中，由易到难设计快速阅读和精读的问题，层层推进各种阅读活动，让学生对阅读内容从整体感知到细节理解，最后深层读懂整篇文章，同时加强阅读策略的指导，让每个学生都主动参与课堂教学活动，最终达到提高阅读能力的目的。Step 4 Post-readingGroup Activities四人小组共同合作，在老师的适当指导下，就以下2个问题展开讨论，让学生就所知、所学、所感和所想融入话题，然后抽若干同学代表作小组发言。1.

人教版高中地理必修2煤城焦作出路何在说课稿
分析过焦作市的地理概况和产业优势后，就需要针对由于资源枯竭所带来的问题提出合理化的建议。既然是谈经济转型，就应该将话题的范围明确在这一领域内。通过材料3的相关内容，我们了解到焦作市需要在产业结构调整、培育新的优势产业、增强综合竞争力等三个整改方针上下功夫。因而引导学生针对优势与不足提出建议，以三个整改方针为基准，衡量建议的可行性是锻炼学生解决此类问题的有效途径。在此我将教会学生的是解决问题方法而非案例的内容，正所谓“授之以鱼，不如授之以渔”。接下来针对学生的建议和教材资料分析所罗列的10点整改思路，由学生自由发言提出看法，通过教师的指导和学生的讨论，进而确定经济转型建议的具体方案。最后注意将建议与产业优势相对照，看建议是否都是围绕着产业优势而提出的，这样做会加深学生的印象，通过建议和优势的对应关系，将不难找出此类问题的解题思路。
中班听说《猜莲子》说课稿
（一）游戏导入。在这个活动的开始，老师和孩子们围坐成半圆形，这样就自然地缩短了老师和孩子们之间的距离，孩子们会觉得老师很亲近自己，为游戏情景的设置打好了情感基础。接着，老师出示莲蓬剥出莲子“这是什么呢？对，莲子。我们要在池塘里种上莲子，明年才能结出莲蓬。今天，请小朋友扮演池塘里的泥，老师把这颗莲子种到池塘里，大家一起玩一个种莲子的游戏。”良好的游戏情景自然的设置好了，这也是激发孩子们参与的兴趣、集中孩子们注意力的一种很好的策略。（二）交代游戏规则及玩法。游戏规则有以下几点：1、扮泥的小朋友必须将眼睛闭起来，不能偷看，等儿歌念完后才能睁开。2、种莲子的人会在儿歌结束前将莲子放在一个小朋友的手里，并且用简短的语言来描述这个小朋友的外貌特征，请大家来猜。3、被猜出的小朋友必须重复说出自己的外貌特征。
说话要算数 说课稿
说教材本课时的教学要点是引导学生分析失信的原因，找到解决的方法，并懂得和做到对自 己守信。数师可以按照教材内容的编排顺序进行教学，先设计讨论活动，引导学生针对具体的失信行为分析原因，井能对症下药,找出相应的解决方法，然后转向“对自己说话算数" 的内容。对此，教师可以通过数材中“张明对自己说话算数”的内容，引导学生思考并讨论 为什么要对自己守信，从而让他们认识到无论是对别人还是对自己都旻言行一致、说话算数.教师旻强调对自己说话算数主要靠自觉和白律，并让学生学习史多的守信方法,并运用在自己的守信实跋中。学情分析诚信对学生来说是老生常谈，在学校或是日程的生活中，老师、长辈总会要求孩子能做到诚实，不说谎。但实际上，很多孩子乱下保证，却常常做不到，导致失信，但在他们眼中这并不算是不诚信。因此我们需要在根本上改变他们的这一认识与看法。通过角色扮演在帮别人改正说话不算数的毛病过程中，自 纠身上存在的失信问题并改正。
