部编人教版五年级下册《刷子李》说课稿（一）
一、说教材：我所执教的《刷子李》选自冯骥才的《俗世奇人》。是五年级下册中的一篇课文。“刷子李”普普通通，却有“俗世奇人”之美称。首先是“俗世”中的“凡人”，因为他是生活于市井里巷的凡夫俗子，是一位普普通通的手艺人；可他又是“俗世”中的“奇人”，因为他刷墙的技艺高超，让“行外的没见过的不信，行内的生气愣说不信”。他有才能、有个性，喜怒哀乐样样俱全，但行事言语又高于常人，所以，用“俗世奇人”之称最为恰当。这篇短文以“刷子李”的高超手艺为话题。作者写“刷子李”的奇妙绝活时，首先极力写他手艺之高，“他要是给您刷好一间屋子，屋里什么都不用放，单坐着，就如同升天一般美。最让人叫绝的是，他刷浆时必穿一身黑，干完活，身上绝没有一个白点。”然后作者从一个小徒弟的视角印证了“刷子李”的真功夫：起初，徒弟是“半信半疑”，但大半天下来，居然连一个芝麻大的粉点也没发现，他真觉得这身黑色的衣服有种神圣不可侵犯的威严。
部编人教版五年级下册《景阳冈》说课稿（一）
全文按事情发展的顺序，可分为“喝酒”、“上冈”、“打虎”、“下冈”四部分。纵观全文，有如下特点：1.篇幅较长，适合学生进行快速默读训练。2.本文生字和难读字较多，在布置预学作业时，重点是鼓励学生多花时间掌握生字新词。3.课文中出现了许多学生日常阅读中较少出现的文言词汇，很多字词的古今意义相差较大，在理解上造成了一定的困难。只有在扎实理解这些词汇的基础上，才能顺利地理解课文。4.教材在具体描写人物时，突出了武松的语言、心理和动作。特别是描写“打虎”一章时突出了武松的动作描写，而在“喝酒”一章中则强调了人物的语言。“上冈”时着重表现人物心理。因此在阅读指导中，应紧紧抓住人物的对话，心理和动作，来指导学生概括分析人物个性品质，这是本课的训练重点。
部编人教版五年级下册《古诗三首》说课稿（一）
三、说学情：五年级的学生在古诗学习中已经积累了一定的经验，对文本有独特的阅读体验。课文所描写的情景又都与儿童有关，反映儿童生活，学生也可能有着相似的亲身经历，符合学生的心理，容易引起学生情感的的共鸣，进而在阅读古诗中获得感知，加以模仿，发展想象力，锻炼学生的理解能力和语言表达能力。四、说教法和学法：1.说教法：教学中，设置情景，激发学生认知兴趣，调动学生主动学习的欲望，引导学生主动探究。使学生这一教学主体主动积极地进行语言文字的学习和探究。2.说学法：教学过程体现“以读为本”的新课标理念，教学中，始终让“读”贯穿着整个教学过程。引导学生在读中感受古诗词的优美精湛的语言文字和丰富的人文内涵；在入情入境的读中有所感悟和思考；在读中受到情感的熏陶，获得思想的启迪。
