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。
人教版高中语文必修1《人性光辉：写人要凸显个性》说课稿2篇
人教版新课标教材必修一的“表达交流”部分，有一个专题是“人性的光辉——写人要凸显个性”。其中的“写法借鉴”部分列举了两则人物描写实例，并归纳出人物描写的几个要点。其训练的思路和方法是很明显的，但所列举的人物描写的实例却不够典型。而必修一第三单元正好是学习写人记事散文，其中的两篇自读课文《记梁任公先生的一次演讲》《金岳霖先生》又是写人记事非常典型的文章，故而我尝试将这两篇文章作为实例和。写人要凸显个性。写作指导结合起来教学。这样设计还有一个目的，那就是解决课程改革中教学内容多而课时紧张的矛盾，提高课堂教学效率。师：今天，我们一起来学习“写人要凸显个性”。这两堂课分四个步骤来完成：一、先学习教材中关于写人方法的介绍，约15分钟；二、快速阅读第三单元的《记梁任公先生的一次演讲》和《金岳霖先生》两篇文章，具体感受其写人的方法，约30分钟；
《江城子·乙卯正月二十日夜记梦》说课稿 2022-2023学年统编版高中语文选择性必修上册
一、温故导入好的导入未成曲调先有情，可以取得事半功信的教学效果。对于本节课我以温故知新的方式导入，以苏轼的《赤壁赋》和《念奴娇》引导学生感受苏轼的豪放和阔达，从学生熟悉领域出发，引导学生探究他内心深处的“柔情似水”，感受他的“十年生死”之梦。二、诵读感知（亮点一）《语文课程标准》中建议“教师要充分关注学生阅读需求的多样性，阅读心理的独特性”。所以在本环节我将综合运用听、读、问、答四种方式教学。首先通过多媒体听读，激发学生学习兴趣，直观感受苏轼的痛彻心扉和伤心欲绝。其次指定学生诵读，并在诵读之后，由学生点评，加深学生对于断句、轻重、快慢的理解，进一步感受本词的凄苦哀怨。最后配乐读，利用凄清的音乐引导学生通过自己的诵读来表现诗中所蕴含的真挚之感。设计意图：通过多种阅读方法，反复阅读本词，引导学生由浅入深的理解本词的思想内容和艺术风格，初步感受作者对妻子的挚爱之情和他的痛彻心扉，加深学生对文章的理解。
古诗词诵读《拟行路难（其四）》说课稿 2021-2022学年统编版高中语文选择性必修下册
（一）导入新课“时势造英雄”，恶劣的环境造就名诗名篇。正因如此，怀才不遇于古人是恒久的情感素材。同学们，请大家回忆我们学过哪些抒发作者怀才不遇的诗词？（二）解释题意拟：仿照，模拟《行路难》，是乐府杂曲，本为汉代歌谣，晋人袁山松改变其音调，创制新词，流行一时。 鲍照《拟行路难》共十八首，歌咏人世的种种忧虑，寄寓悲愤，今天我们学习的是其中第四首。（三）作者简介、写作背景门阀制度之下，“上品无寒门，下品无世族”，出身寒微的文人往往空怀一腔热忱，却报国无门，不得不在壮志未酬的遗恨中坐视时光流逝。即使跻身仕途，也多是充当幕僚、府掾，备受压抑，在困顿坎坷中徒然挣扎，只落得身心交瘁。
高中物理人教版必修一《弹力》说课稿
二、学情分析：学生目前对形变和弹力有一定的感性认识但是不够深入；知道支持力、压力都是弹力，但是不能够概括产生的原因。理性思维还没有达到一定的层次，要想理解弹力这一抽象概念还有一定困难。因此我采取引导、启发的教学方式。
人教版高中地理必修3区域工业化与城市化—以我国珠江三角洲地区为例说课稿
A.城镇数量猛增B.城市规模不断扩大【设计意图】通过读图的对比分析，提高学生提取信息以及对比分析问题的能力，通过小组之间的讨论，培养合作能力。五、课堂小结和布置作业关于课堂小结，我打算让学生自己来总结，你这节课学到了什么。这样既可以提高学生的总结概括能力，也可以让我在第一时间内获得它们的学习反馈。(本节课主要学习了珠三角的位置和范围以及改革开放以来珠三角地区工业化和城市化的发展。)关于作业的布置，我打算采用分层次布置作业法。第一个层次的作业是基础作业，要求每一位同学都掌握，第二个层次的作业是弹性作业，学生可以根据自己的情况来选做。整个这堂课，老师只是作为一个引导者、组织者的角色，学生才是课堂上真正的主人，是自我意义的建构者和知识的生成者，被动的、复制式的课堂将离我们远去。
人教版高中地理必修3区域农业可持续发展—以我国东北地区为例说课稿
（3）师生讨论，提升思维深度。教师引领学生将讨论由农业生态破坏、土地利用不合理等表象问题逐步深入到农业结构不合理、农业技术落后等深层问题，提升了学生思维的深度。（4）角色体验，突破难点落实重点。在农民与保护区工作人员的角色体验活动中，学生们尝试换位思考，在冲突与交锋中，在教师的引领下，重新认识环境保护与区域经济发展的关系，在情感体验中加深对可持续发展内涵的理解，小冲突凸显大矛盾是本课设计的创新之处。2．注重对地理问题的探究，突出地理学科本质。地理学科具有综合性、区域性特征，区域差异及人地和谐发展观是我们在教学中应该把握的基本特征，也是我们应当把握的地理学科的本质特征，因此在本节课的设计中我注重抓住地理事物的空间特征、综合性特征，以突出地理学科的本质。

人教版高中语文必修1《奥斯维辛没有什么新闻》说课稿2篇
第11段很短，只点出了这是“在妇女身上搞不育试验的地方”，但在最末又加了一句“否则他会羞红了脸的”，这是为什么？那肯定是一个极为肮脏，极为残酷的地方。据资料记载：当时的希特勒制定一项令所有被征服或占领国家的民族充当奴隶并且逐渐消亡的隐密性种族灭绝计划——高效率、大规模的强制绝育。为此，数以百计的纳粹医生、教授、专家甚至护士，在行政管理专家的通力合作下，相继提出了几十种绝育方法，十余种实施方案，并且在奥斯维辛、拉芬斯布吕克、布亨瓦尔特、达豪等十多个大型集中营内对数以万计的犹太、吉普赛囚犯、因从事抵抗运动而被捕的政治犯和男女战俘进行了残酷的手术试验，造成他们大量死亡或者终身残疾、终身不育。这样残酷的毫无人性的手段，任谁也不愿看到。
人教版高中语文必修1《别了，“不列颠尼亚”》说课稿2篇
一、说教材《别了，不列颠尼亚》是编排在人教版《普通高中课程标准实验教科书语文1（必修）》第四单元的课文，是精读课文《短新闻两篇》中的一篇，另一篇是《奥斯维辛没有什么新闻》。这一单元的学习内容是新闻和报告文学，还有两篇作品分别是中国报告文学三大里程碑之一的《包身工》和记录中国航天事业辉煌发展的《飞向太空的航程》。在当今信息大爆炸的时代，如何快速获得信息，如何在新闻中解读事件的真相，感悟生活的内涵成为语文教学的又一重大任务。因此这一单元的编入便更多地具有了时代意义，体现了语文学科与日常生活的密切关系。不仅如此，新闻特写和报告文学的选入，拓宽了学生对新闻类文章的了解，体现语文学科的工具性作用。在选文的过程中，新教材同时注重语文学科的人文性，四篇作品不仅传递着新鲜、真实的信息，同时更张显人文性的厚度，他们以饱满的情感，纵横的历史经验。
人教版高中语文必修2《孔雀东南飞并序》说课稿2篇
4、问题策略。引导学生提出问题、提出有价值的问题，是探究性学习的难点，也是课堂教学最有活力、最具创造力的亮点。我设计的课堂问题有：诗歌着力赞颂刘焦坚贞爱情和反抗精神，但他们许多地方却表现的非常顺从呢？焦母如此专横固执，为什么在焦刘悲剧发生后又要求合葬呢？这些由诗句生发的问题，会深深打动作学生的心灵，诱导学生去读诗，去背诗，去体味诗。5、手段方法。借助多媒体课件10个幻灯片、课文音频诵读资料、课文相关的文字资料，采用诵读法、讨论法、探究法等教学方法进行本课教学。6、板书设计：板书是教学内容的浓缩。根据教学重点和本诗特色，我的板书分预设和生成两块。预设板书设计有文章标题、情节结构、艺术特色三部分。文章标题孔雀东南飞情节结构被遣——誓别——抗婚——殉情——化鸟艺术手法①人物对话的个性化②铺陈排比的手法③起兴和尾声
