人教版新课标小学数学四年级下册小数的读法和写法说课稿2篇
【虽说读小数是这节课要掌握的知识，但我们不难发现，只要学生开始接触小数，就必定要把它读出来。因此在四年级的时候，学生已经会读小数了。如果学生的读法不规范，那么教师也必然会予以指正，只不过没有向学生说明白而已。因此，我改变了教材的编排体系，将读小数的读法安排在课的第二步，既使学生获得了情感的满足需要，又为后面的新知探究创设了自然的衔接。如果有个别学生产生错误，可让其他学生予以指正，并授于方法，让双方学生都获得满足：情感满足与知识获取的满足。小数的读法有两种，一是直接读，二是根据小数的意义读。根据参考书的意见，我只要求学生掌握第一种读法。】三、教学小数的写法1、出示例3：据国内外专家实验研究预测：到2100年，与1900年相比，全球平均气温将上升一点四至五点八摄氏度，平均海平面将上升零点零九至零点八八米。
人教版高中政治必修2处理民族关系的原则-平等、团结、共同繁荣说课稿
环节四 情感升华，感悟生活播放《爱我中华》，感受祖国的伟大，民族的团结。设计意图：使学生感受伟大的中华民族的精神，内心产生共鸣，抒发强烈的爱国热情。教师带领学生一起合唱，用歌声结束本堂课内容，能再次唤起学生的爱国情感，使学生认识到：维护国家统一和民族团结是每个公民的义务。环节五 课堂小结 巩固知识本节课我采用线索性的板书，整个知识结构一目了然，为了充分发挥学生在课堂的主体地位，我将课堂小结交由学生完成，请学生根据课堂学习的内容，结合我的板书设计来进行小结，以此来帮助教师在第一时间掌握学生学习信息的反馈，同时培养学生归纳分析能力、概括能力。本节课，我根据建构主义理论，强调学生是学习的中心，学生是知识意义的主动建构者，是信息加工的主体，要强调学生在课堂中的参与性、以及探究性，不仅让他们懂得知识，更让他们相信知识，并且将知识融入到实践当中去，最终达到知、情、意、行的统一。
人教版高中历史必修2战后资本主义世界经济体系的形成说课稿3篇
1、《战后资本主义世界经济体系的形成》是人教版高中历史必修Ⅱ第八单元第22课，学时为1课时。《历史必修Ⅱ》一书用古今贯通、中外关联的八个专题来着重反映人类社会经济和社会生活领域发展进程中的重要史实。从第一单元勾勒“古代中国经济的基本结构与特点”再到第八单元“世界经济的全球化趋势”，以历史唯物主义观点清晰阐明经济全球化是世界生产力发展的要求和结果，是不以人的意志为转移的历史必然趋势。第八单元的标题是《世界经济的全球化趋势》，作为最后一单元，从内容上讲，有强烈的时代感和现实意义，是全书内容的总结与升华展望。提起“全球化”这个十年前才首次出现在美国《商业周刊》的新名词，如今却是地球人都知道了。然而究竟什么是全球化？作为一历史现象，全球化有其自身内部严密完整的体系，其中核心之一便是制度、规则的全球化，而这正是本课内容的着力点。

1、课题引入：11月16日9时40分许,甘肃庆阳市正宁县榆林子镇发生一起重大交通事故，“校车安全”又一次甚嚣尘上，我设计提问“校车安全事故然表面是偶然，但又是一种必然，你认为事件的原因何在？”的问题激发学生的阅读兴趣。我设计典型事例，通过学生讨论，教师总结的形式，并得出主次矛盾辩证关系的原理分析。2、具体分析事件背后的原因，从原因中发现，这众多的原因矛盾中，都有主次方面之分，由于得出矛盾的主次方面原理。3、从原因中，寻找对策，既坚持重点论与两点论的结合。反对一点论和均衡论。4、无独有偶，在2011年在湖南，海南，广西等地均有类似的事件发生。对比各地事故背后的原因，得出应具体问题具体分析。进而分析具体问题具体分析的意义及地位。
人教版高中政治必修4用对立统一的观点看问题说课稿（二）
【设计意图】通过认识自我这一环节的设计，让学生能够准确的理解矛盾的主次方面，做到能够正确的评价事物，尤其是能够正确的认识评价自己和他人，做到扬长避短，从而达到情感态度价值观目标。为了更好的区分主次矛盾与矛盾的主次方面，在此我以小组赛的形式设计了【我用我学正确识别】这一学生合作探究活动来强化对知识的掌握。（用时大约6分钟）。通过对难点主次矛盾和矛盾主次方面的深入学习，师生共同找出其共同之处：均是两点与重点，从而讲解主次矛盾和矛盾主次方面共同的方法论要求：坚持两点论与重点论的统一。3、坚持具体问题具体分析（约8分钟）由于第二目知识点具体问题具体分析内容上比较简单，因此在过渡后主要以学生自学为主，我围绕“成功”制作两个幻灯片作简单讲解与归纳。

人教版高中生物必修3第三章第一节《植物生长素的发现》说课稿
（5）根据实验的第五部分——验证性实验结果，证实了达尔文关于植物向光性运动原因的假说――确实存在一种物质致使胚芽尖端产生了向光运动。这样通过多个实验的多媒体演示过程，强化学生的思维，最终在学生的大脑中形成科学研究过程的”条件反射”。为了使学生初步学会”设计对照实验的方法”，首先也利用多媒体的演示实验，并在其中特意设置一些”陷阱”，通过多次”请学生进入‘陷阱’”，来强化设计实验时应该控制的变量问题，从而在学生的认知领域里初步构建出设计对照实验的知识体系。3、归纳总结1934年，荷兰科学家郭葛等人从植物中分离出了这种能使植物产生向光性的物质，并确定它就是吲哚乙酸。这就真正从化学物质的角度证实了达尔文的假设。在能够从植物体中分离提取出生长素之后，要想知道：除了能使植物产生向光运动之外，生长素对于植物的器官还有什么作用？可以采用哪种方法来进行试验？

新人教版高中英语必修3Unit 1 Festivals and Celebrations-Listening &Speaking＆Talking教学设计
The theme of this section is “Talk about festival activities and festival experiences”.Festival and holiday is a relaxing and interesting topic for students. This part talks about the topic from the daily life of students’. In the part A ---Listening and Speaking, there are three conversations among different speakers from three countries(Japan, Rio and China), where the speakers are participating in or going to participate in the festivals and celebrations. So listening for the relationship among them is a fundamental task. Actually, with the globalization and more international communication, it is normal for Chinese or foreigners to witness different festivals and celebrations in or out of China. In the Conversation 1, a foreign reporter is interviewing a Japanese young girl who just had participated in the ceremony of the Coming-of-Age Day on the street and asking her feeling about the ceremony and the afterwards activities. Conversation 2, Chinese girl Li Mei is witnessing the Rio Carnival for the first time, and her friend Carla gives her some advice on the costumes which enables her to match with the carnival to have a good time. Conversation 3, a Chinese guide is showing a group of foreign visitors around the Lantern Festival and introducing the customs of the festival to them. The three conversations have a strong vitality and insert the festival and cultural elements from different countries. So perceiving the festivals and cultures from different countries is the second task. At the same time, the scripts also insert the targeted grammar --- v-ing as attributive and predicative, which students can perceive and experience in a real context and make a road for the further study. That is the third task. In the Part B--- Listening and Talking, the theme is “Talk about festival experience”, which is the common topic in our daily conversations. During the conversation, Song Lin, a Chinese student, asked Canadian friend Max about how to spend Christmas. In the conversation, Song Lin talked about experience and the feelings during the Chinese Spring Festival, during which there are not only some enjoyable things but some unpleasant things. After the listening, perhaps students find there are some similarities between Christmas and the Chinese Spring Festival as there are some differences in the origins and celebrations. For example, people always visit friends and relatives, decorate their houses, have a big dinner together, chat and give presents to each other.

Step 3 Analyzing article structureActivity 31. Teachers raise questions to guide students to analyze the chapter structure of this diary and think about how to describe the festival experience. (1)What should be included in the opening/body/closing paragraph(s)?(2)How did the writer arrange his/her ideas?(3)What kind of interesting details did the writer describe?(4)How did the writer describe his/her feelings/emotions during the event?2. Students read and compare the three sentence patterns in activity 2. Try to rewrite the first paragraph of the diary with these three sentence patterns. After that, students exchange corrections with their partners. Such as:●This was my first time spending three days experiencing the Naadam Festival in China’s Inner Mongolia Autonomous Region and it was an enjoyable and exciting experience. ●I'll never forget my experience at the Naadam Festival because it was my first time to watch the exciting Mongolian games of horse racing, wrestling, and archery so closely. ●I'll always remember my first experience at the Naadam Festival in China’s Inner Mongolia Autonomous Region because it was so amazing to spend three days witnessing a grand Mongolian ceremony. Step 4 Accumulation of statementsActivity 41. Ask the students to read the diary again. Look for sentences that express feelings and emotions, especially those with the -ing form and the past participle. Such as:● …horse racing, wrestling, and archery, which are all so exciting to watch. ● some amazing performances● I was surprised to see…● I was a little worried about. . . ● feeling really tiredOther emotional statements:●I absolutely enjoyed the archery, too, but the horse races were my favourite part. ●I'm finally back home now, feeling really tired, but celebrating Naadam with my friend was totally worth it. ●He invited me back for the winter to stay in a traditional Mongolian tent and cat hot pot. I can’t wait!2. In addition to the use of the -ing form and the past participle, the teacher should guide the students in the appreciation of these statements, ask them to memorize them, and encourage them to use them reasonably in writing practice.

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.

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.
