一、 首先我们进行教材分析本课是陕西科学技术出版社出版的小学信息技术课本 六 年级上册第 1 课的内容,小学四年级的下学期学生已经学习了Word,Excel的操作,本课是延续Office系列软件的学习,使学生在原有基础上学会 使用PowerPoint。
(3)内陆和中西部城镇主要以煤和火电为主;广大农村和边远地区大多正从使用农作物秸秆等生物能源。(4)人均能源资源不足。我国是世界第三大能源生产国和第二大能源消费国,而我国能源短缺,特别是油气资源短缺已成为制约我国经济发展的重要因素。相关数据——煤炭、石油和天然气的人均资源占有量只有95t,世界平均值为209t,约是世界人均值的1/2;我国人均石油可采储量3t,世界平均值为28t,约为世界平均值的1/10。我国人均能源消费量不足1.2吨标准煤,居世界89位,不足世界人均能源消费水平的一半,仅占发达国家的1/5~1/10。其中人均消费650kg标准煤,是世界平均额的95%;人均消费石油相当145kg标准煤,为世界平均数的16.8%;人均消费天然气相当17.7kg标准煤,为世界平均数的3.9%;人均消费电力501.5kWh,为世界平均水平的25%。(5)是能源消费结构不合理,突出存在着一低两高:即电能消费比例低,非商品生物能源消费量高,一次性商品能源消费中原煤消费比重高。原煤消费达到75%,远高于26.2%的世界平均水平。
2、教学目标根据我对教材的理解、结合学生的实际情况、渗透新课程的教学理念,为提高全体学生的科学素养,按课程标准,以促进全体学生发展为目的。从知识与技能、过程与方法,情感态度与价值观三个方向培养学生,拟定三个教学目标:知识与技能:(1)知道什么是动能。(2)正确理解和运用动能公式分析、解答有关问题。(3)掌握外力对物体所做的总功的计算,理解“代数和”的含义。(4)理解和运用动能定理。过程与方法:通过演绎推理过程,培养科学研究兴趣,领略物理学中所蕴含的严谨的逻辑关系。情感、态度、价值观:通过运用动能定理分析解决问题,感受成功的喜悦,培养学生对科学研究的兴趣。3、教学的重点和难点重点:理解动能定理、应用动能定理解决力学问题。难点:应用动能定理解决多个过程的力学问题,以及变力做功或曲线运动中的动能定理运用。
设计意图:通过设疑、讨论及学生的亲身体验与教师的引导,得到描述圆周运动快慢的两个物理量,也就成功的打破了学生在认识上的思维障碍,突破了物理概念教学的难点。在解决线速度和角速度的问题之后,我将引领学生学习匀速圆周运动的概念以及匀速圆周运动中线速度、角速度的特点。并引出匀速圆周运动中周期、转速的知识。为了加深学生对线速度、角速度与半径关系的认识,我设计了第三个学生体验活动:四名学生以我为圆心做圆周运动,四名学生始终并列,这时里圈同学走动不急不慢,而外圈同学则要小跑。通过学生的活动,不难发现在角速度相同的情况下,半径越大的线速度也越大。定性的得到了线速度、角速度与半径的关系。接下来让学生利用所学知识推导线速度、角速度与半径的关系。设计意图:这样就通过设疑、学生猜想、体验、推导的方式得到了结论,突破了本节课的难点即线速度、角速度与半径的关系。

Example:One day, a poor boy who was trying to pay his way through school by sending newspapers door to door found that he only had one dime(一角)left. He was so hungry that he decided to beg for a meal at the next house.However, he lost his nerve when a lovely young woman opened the door. Instead of a meal he asked for a drink of water. She thought he looked hungry so she brought him a large glass of milk. He drank it slowly, and then asked, “How much do I owe you?” “You don’t owe me anything,” she replied, “Mother has taught me never to accept pay for a kindness.” “Then I thank you from the bottom of my heart.” With these words, Howard Kelly left that house.Years later the woman became badly ill and was finally sent to the hospital in a big city. Dr. Howard Kelly, now famous, was called in. When he heard the name of the town she came from, a strange light filled his eyes. Dressed in his doctor’s clothes, Dr. Kelly went into her room and recognized her at once. From that day on, he gave special attention to her, and decided to do his best to save her life.At last the woman was saved. Dr. Kelly asked the business office to pass the final bill to him. He looked at it and then wrote something on the side. The bill was sent to the woman’s room. She was afraid to open it because she was sure that it would take the rest of her life to pay for it off. Finally she looked, and the note on the side of the bill caught her attention. She read these words: “Paid in full with a glass of milk, Dr. Howard Kelly.” Tear of joy flooded her eyes.

1. 这个寓言是一个关于一位国王古寓言。 The fable is an old fable about a king.2.作者用这个故事让读者对于社区的问题负有个人责任的必要印象深刻。The author used the story to impress upon readers with the need to take personal responsibility for problems in the community.3. 这个故事十分成功的实现了它的目的。The story was quite successful in achieving its purpose.Step 7 WritingPlease write a review of the story according the outline above.The fable is an old fable about a king who thought his people are lazy, so he put a large stone in the middle of the road and hides and waited to see if anyone will try to move it.The author used this story to impress upon readers with the need to take personal responsibility for problems in the community. The story was quite successful in achieving its purpose, and I liked it because it had a clear moral.However, while the moral of the story is clear, the actions of the king seemed pointless to me, because none of the characters in the story learnt anything. For this reason, I think there are better stories that can be used to impress upon people with the need for personal responsibility.Step 8 Pair workExchange drafts with a partner. Use this checklist to help your partner revise his/her draft.1. Does the writer give a short description of the story ?2. Does the description include the most important details of the story ?3. Does the writer give his or her opinion about the character or their actions ?4. Is the review well-organised ? 5. Does the writer use the -ing form as the adverbial correctly in the writing ?6. Are there any grammar, spelling, or punctuation errors ?Step 9 HomeworkPut up your revised draft in the classroom or read it to your class.

师:在科学发展过程中,前一个理论体系的不完善之处,往往是新的研究和新的发现的突破口。开普勒之后,意大利天文学家伽利略创制了天文望远镜,用更加精确的观察继续发展和验证哥白尼创立的新天文学理论。除了用望远镜进行天文观察以外,伽利略还开始进行自然科学的实验研究,哪位同学能给大家讲一讲伽利略在比萨斜塔上所作的关于物体自由下落的实验?生:(讲述这一实验)师:所以,伽利略在科学方面更加重要的贡献是奠定了近代实验科学的基础。(2)实验科学和唯物主义师:伽利略从实践上开辟了实验科学的方法,而英国唯物主义哲学家培根则从理论上阐述了实验科学的方法——归纳法。培根和伽利略同被称为实验科学之父,培根还有一句影响深刻的名言:“知识就是力量”,表明了他注重知识,尊崇科学的精神。我们再来概括一下意大利哲学家布鲁诺的唯物主义思想,是否有同学可以简述布鲁诺的生平事迹?
师:“两开”是什么意思啊?注解里是怎么说的?第二次开,也就说他在这个地方已经待了两年了,这里是他回家的路途中,是不是?路途中他停留了两年时间。好的,你先请坐。你觉得残菊不能两开,在理解上好像存在一些误差。赵勇:因为菊花古往今来代表着对家乡的思念。师:菊花代表对家乡的思念?(下面学生齐笑)这种说法牵强了些,菊花在古代象征着高洁,梅兰竹菊是四君子嘛。赵勇:写这首诗时,他已经打算回故乡了,所以不应该写“残菊”,写“残菊”的话……师:事实上,他回不了故乡。好的,请坐。再想想,“残菊”意味着什么?破败。“丛菊”呢?茂盛。那这里说“两开他日泪”,“两开”是什么意思?开了两了次了,这说明他在这里已经待了两年了。那“他日泪”又是什么意思?赵勇:应该是他看到这里的菊花开得这么茂盛,就想到了故乡的菊花也是开的茂盛的时候。如果是“残菊”的话,那故乡的菊也会开得很残败。(下面学生齐笑)
第三,说教学重点和难点。根据课程标准的具体要求、学生实际和社会实际以及教材的逻辑结构和教学体系,我认为本课的重难点是以下几个方面。教学重点:1.理解王昭君的形象2.深入理解杜甫在诗中的情感教学难点:理解寓意,把握主旨。第四,说教法与学法。教法:根据课文特点和学生实际情况,以诵读法(示范朗读、学生齐读)、问题探究法、点拨法、讨论分析法进行教学。首先激发学生学习本文的兴趣;然后引导学生反复吟哦诵读,在读的过程中质疑、思考、品析、鉴赏;最后在教师适当的点拨下,在集体的热烈讨论中,理解作者的感情,得到新的认识。(解说:使学生在教师的主导下围绕中心议题发表各自的意见,相互交流,相互启发,相互争议,激发他们主动去获取知识,培养健康情感。)
1、汉武帝尊儒的措施:(1)政治方面:起用很多儒学家参与国家大政。他规定,地方定期选出孝子、廉吏当中央任官,甚至还擢升平民、儒士为相。这明显扩大了官员的队伍,提高了官员的文化素质,巩固了封建统治基础,成为汉武帝文治武功的重要组成部分。也给后世封建王朝在用人方式方法上面提供了宝贵的借鉴和启迪。(2)思想方面:采纳董仲舒的建议,“罢黜百家 独尊儒术”(3)教育方面:儒家经典“五经”为国家规定的教科书。兴办太学和设立地方学校进行儒学教育。公元前136年,汉武帝正式规定《诗》、《书》、《礼》、《易》、《春秋》为“五经”;前124年,又在长安兴办太学,规定太学生员为博士弟子,一律由儒家五经博士负责教授,学完经考试合格后即可到政府任官。这是封建国家利用政权的力量兴办教育、提倡儒学,其必然对整个社会的教育事业有一定的导向作用。
(一)、教材地位:我说课的内容是人教版高二历史(必修3)第五单元《从“师夷长技”到维新变法》。本课主要讲述了鸦片战争后中国思想界发生的巨大变化,所讲述内容对中国近百年的历史走向,对近代中国政治发展所产生的影响是至关重要的,所以这节课在教材中具有重要的地位和作用,同时也是本册书中的重要章节。(二)、课标要求:《高中历史新课程标准》对这一节内容作了这样的要求:了解鸦片战争以后中国人学习西方 寻求变革的思想历程,理解维新变法思想在近代中国社会发展中所起的作用。(三)、教学目标:根据课标要求、教材内容和学生的具体情况,确立以下教学目标:1、知识与能力:(1)识记:林则徐被称为“开演看世界的第一人”;魏源的“师夷长技以制夷”思想;洋务派“师夷长技以自强”思想;早期维新思想和90年代维新思想;
过度:诚如牛顿所说 我之所以能够取得今天的成就有很大原因是站在巨人的肩膀之上设问3:为什么这个时代选择了达尔文来完成这一伟大的发现呢?(达尔文的个人努力)补充材料:(1831年起,他随“贝格尔号”考察舰进行环球考察5年。考察结束后,在整理考察资料和实物标本的基础上,经过长期的研究,于1859年出版了《物种起源》一书,确立了生物的进化论说明达尔文的个人努力:学习、考察、学习、不迷信权威、勇于挑战、不断探索的精神,饱览群书,挑战和假设建立在大量的阅读和观察的基础上,科学实证等等。可以说达尔文身上有那个时代的一个浓缩的特征,当然他还有点运气,不过,机遇永远是为那些有准备的人提供的。)探究:达尔文“进化论”的影响思路引领:科学理论发展的影响可以从哪些方面分析?(经济、科学理论本身、人文学科、社会影响(对宗教,社会),对其他国家的影响)设问:达尔文进化论对1859年及以后的社会带来了非常深远的影响。有哪些影响呢?①挑战封建神学的神创世,促进人类认识的飞跃
2、互联网的功用:(1)功用:提供文件传输、电子信箱、聊天等服务,在社会各个领域发挥了巨大的作用,标志着信息化社会的出现。(2)特点:网络媒体作为一种新的传播媒体,具有界面直观、音色兼备、链接灵活和高速传输的特点。3、互联网的影响:教师提问,学生思考回答,教师总结 (1)信息经济在世界各地全面发展,加快了经济全球化的步伐;(2)传统产业也借助互联网提高管理水平,并通过全球营销和采购扩大市场;(3)在互联网时代,人们可以在家里完成很多工作,提高了工作效率,增加了乐趣;(4)人们的社会交往方式也发生着改变。(5)也带来一些负面影响。【合作探究】3:青少年如何对待网络:互联网在给社会带来巨大效能的同时,也带来了巨大的挑战。青少年应该提高自身的道德素养,树立正确的网络观,让网络发挥出应有的作用。
一、教材地位《音乐与影视艺术》是人教版高中历史必修(III)第八专题中的第三节内容。音乐、影视艺术属于意识形态范畴,是当时政治、经济的反映,是社会进步的产物。19世纪以来的音乐与影视艺术糅合了近代科学技术的元素,直接引领着文明发展趋势和社会风尚,满足人们不同层次的审美需要和精神追求。音乐、影视艺术在人类日常生活中无处不在,已经成为人们日常生活中的重要组成部分,所以具有重要地位。本课分三个部分介绍了19世纪和20世纪音乐的发展与变化以及影视艺术的产生发展。下面我就谈谈对这节课的教学思路。二、教材分析1、课标要求课标的要求是:列举19世纪以来有代表性的音乐作品,理解这些音乐作品的时代性和民族性。了解影视艺术产生与发展的历程,认识其对社会生活的影响。2、教学目标根据新课标、教材内容、学生实际,确定教学目标如下:(1)知识与能力:①列举19世纪以来有代表性的音乐作品,理解这些音乐作品的时代性和民族性。
3、问题设计:文化除了影响人们的交往行为和交往方式外,还影响人们的什么?4、师生总结得出结论:文化影响人们的实践活动、认识活动和思维方式。设计意图:通过主题的指引,让学生查阅并说说中国传统节日的来源、传说和意义。这是基于丰富课程资源的设计,将生活和学习领域的多种资源纳入课程的范畴,在活动中自主建构知识,并在教师的引导下,提高分析和解决问题能力,培养热爱祖国的思想感情,突破本框题第二个重点。过渡设问:文化对人影响有什么特点?设计意图:通过问题提示,集中学生的注意力,导入下一个环节的教学。环节三:文化对人潜移默化的影响。教案:1、多媒体播放“孟母三迁”故事动画片。2、讨论问题:“孟母三迁”的故事给我们什么启示?3、师生总结得出结论:文化对人具有潜移默化的影响。设计意图:“孟母三迁”的故事学生比较熟悉,而且这个故事的思想教育性较强。
师:建立社会主义思想道德体系,必须牢固树立社会主义荣辱观。在我们的社会主义社会里,是非、善恶、美丑的界限绝对不能混淆,坚持什么、反对什么,倡导什么、抵制什么,都必须旗帜鲜明。我们坚持以热爱祖国为荣、以危害祖国为耻,以服务人民为荣、以背离人民为耻,以崇尚科学为荣、以愚昧无知为耻,以辛勤劳动为荣、以好逸恶劳为耻,以团结互助为荣、以损人利己为耻,以诚实守信为荣、以见利忘义为耻,以遵纪守法为荣、以违法乱纪为耻,以艰苦奋斗为荣、以骄奢淫逸为耻。课堂小结通过本节课学习,使我们认识到中国特色社会主义文化建设的中心环节是思想道德建设,了解什么是社会主义思想道德,为什么要建设社会主义思想道德体系和怎样建设社会主义思想道德体系,大力倡导“爱国守法、明礼诚信、团结友善、勤俭自强、敬业奉献”的基本道德规范。我们要大力加强社会主义思想道德建设,为社会主义各项事业的发展提供强大的精神动力和方向保证。
