大班体育《我们爱运动》说课稿
活动共分四个环节，在开始部分我设计了在音乐的伴奏下玩木头人的游戏，一开始老师和小朋友一起听音乐四散做自己喜爱的动作，音乐一停，老师问：谁是木头人？小朋友回答：我是木头人，同时摆好一个造型不动，老师检查。第二环节的游戏：我最爱运动是本节活动的重点和难点所在，重点是通过让幼儿模仿运动造型，发展幼儿身体动作的协调性；培养幼儿积极参加游戏的主动性并训练他们在行进间躲避同伴，不碰撞的能力。其中在行进间躲避同伴不碰撞是一个难点。为什么要设计这样一个难点呢？我们在生活中常常可以看到孩子们在游玩的时候拼命往前冲，好象整个操场只有他一个人，这样是非常危险的，教会孩子一些躲避的方法就可以避免碰撞事故的发生。在游戏的前面我设计了一个模仿运动员的小环节，目的是让幼儿展示一下自己已经掌握的运动项目，同时也可以大家相互交流一下，看看别人都了解了什么，这样既给孩子一个展示的机会也提供了一个学习的机会。新纲要告诉我们：“培养幼儿对体育活动的兴趣是幼儿园体育的重要目标”在设计游戏内容的时候，我就想用什么形式既能培养幼儿对体育活动的兴趣又能锻炼幼儿的能力，增强幼儿参与的积极性及竞争意识，于是我想到“竞赛”。大家请看，这是教室场地的示意图，中间的五个小圆圈是竞赛点，里面分别写上“我、最、爱、运、动”五个字，外圈是准备区。游戏开始，小朋友和老师一起站在大圈上，听音乐逆时针向前跑，音乐一停，教师问：谁最爱运动，幼儿一边回答：我最爱运动，一边去抢占五个圈，每一个圈里只能站一个人。最先到达圈内的小朋友每人要做一个运动项目的造型，而且不能与别人的重复。再由其他小朋友选出一名做得最好，游戏继续进行，每一轮的优胜者，到最后一起进行决赛。
对初中英语教师说课技能的思考与建议
一、认识说课的实质说课是指教师以现代教育理念为指导，在精心备课的基础上，面对同行或教学研究人员，采用口头语言或相关辅助手段，阐述某学科课程或某具体课程的教学设计及其依据的教学研究过程（李崇爱,孟应周,2011）。简单而言，说课就是教师对“教什么”、“怎么教”、“为什么这么教”等问题进行阐述。这样做的目的，一方面可以展现一个教师的教育理论修养、教学组织能力和口头表达能力，另一方面可以帮助教师优化教学设计，反思教学行为，分享教学经验。
部编人教版五年级上册《 落花生》说课稿
（1）主要内容：《落花生》一文是五年级上册第一单元的一篇讲读课文。课文都是作者通过由生活中事物领悟到的人生哲理。五年级的孩子思维活跃、求知欲强、乐于表达、愿意交流，正是引导他们明事理、辨是非，培养人文素养、提高语文能力的关键期。学习上，他们也具有一些学习能力，掌握了一些学习方法，这更需教师进一步引导，循循善诱，让学生在学习中生活，在生活中学习。因此，本课教学设计以引导学生“领悟人生、了解写法、关注生活”为主线，进一步领导学生走入文本、感受情感、领悟生活。《落花生》这篇课文通过介绍作者一家人过花生收获节的经过，通过收获节上对花生好处的谈论，让学生懂得：人要做有用的人，不要做只讲体面，而对别人没有好处的人。（2）教学目标：本课的教学目标有以下四点：1.学会本课生字，正确读写词语。
大班科学《物体怎样移动》说课稿
“物体的移动”除了教幼儿获取有关的物体移动需要的具体经验外，还要对幼儿进行相关的科学知识教学，并从科学探索出发，生成有关技术的目标和内容，将幼儿的科学与技术学习有机地、自然地结合起来。在教幼儿“物体怎样移动”的之前，我预设了一下“物体怎样移动”的学前目标：首先，引导幼儿在玩的过程中，自己尝试让物体动起来，使幼儿感受物体运动和力的关系，获取有关物体移动需要力的具体经验。其次，让幼儿尝试用力大和用力小的时候，物体移动的一样吗？再次，让幼儿想办法在不用身体碰物体的情况下，还有什么办法让物体动起来？最后，要培养幼儿的观察力，并激发幼儿探索自然现象的兴趣。在学习 “物体怎样移动”的时候，教师为幼儿共同准备了各种物体。如：积木、汽车、纸、圆珠笔、各类玩具以及绳子、轮子、木板等等。为了让幼儿更好的投入到活动中去，在进入教室之前，我领着幼儿在室外活动了一下。随后我放开音乐，幼儿听着音乐《碰碰车》来到了教室，看到地上放着各类玩具，顿时来了兴趣。我趁机说：“小朋友们，地上放了这么多的玩具，我好想玩一玩，你们想玩吗？”说完，我就独自拿着玩具玩起来，小朋友也跟着玩起来。在我的启发和引导下，孩子们开始了活动中的第一次尝试，在这一环节中，教师给了幼儿自由探索的空间和材料，让幼儿通过尝试，发现物体自己是不动的，只有去推它碰它物体才会移动。

人教版高中地理选修1月球和地月系教案
月球对地球的意义月球与地球形影相随，关系密切。月球对地球的影响，主要有以下几方面：1．地球上夜晚的自然照明，主要靠月亮。2．远在古代，人们就根据月相变化的周期，编订历法。我国农历月份的安排，是以月相变化 周期为标准的。农历规定朔为初一，这样，望就在十五日或十六日。我国人民的传统节日，像春节、中秋节就是按农历的月日计算安排的。3．由于地球表面各处所受月球和太阳引力的不同，地球上的水体产生了明显的潮汐现象。4．月球是人类星际航行的第一站。已知月球表面有多种宝贵矿藏；重力较小；没有大气层，利用太阳能的条件较好。如何利用月球的特殊环境，开发月球的资源，以及如 何利用月球作“码头”，使人类更好地研究宇宙，这将是月地关系的新篇章。

5.对土星五号火箭和登月舱的质疑现代航天飞机只能把20吨载荷送上低轨，而当 年的土星五号却能轻而易举地把100吨以上载荷送上地球轨道，将几十吨物体推出地球重力圈，为什么后来却弃而不用，据说连图纸都没有保存下来？6.温度对摄影器材的影响月面白天可达到121°C，据图片看，相机是露在宇航服外而没有采用保温措施的。胶卷在66°C就会受热卷曲失效，怎么拍得了照片？这些人士认为，对以上这一切美国政府一直没个 交代，而知情者由于担心生活和安全受到影响，甚至可能直接遭到了胁迫，至今对此沉默不言。但相信不久的将来，诞生于美苏太空竞赛年代的“登月骗局”定会水落石出。反驳不过，也有许多人认为“阿波罗”登月计划不可能造假：首先因为该计划当时是在全球实况转播的，近亿人亲眼看到。另外，宇航员还从月球带回了一些实物，如岩石。
