人教版新课标高中物理必修1牛顿第二定律说课稿2篇
进一步引导学生思考利用数学知识可写成等式F=kma学生很自然就会思考比列系数K应该是多少？通过教师引导学生举例各国长度单位不同（如英国：英里、码、英尺、英寸；中国：市里、市丈、市尺、市寸、市分 ）导致交流不便。为了适应各国交流需要国际计量局规定了一套统一的单位，称为国际单位制 。取不同的单位制K是不同的，为了简洁方便，在选取了质量和加速度的国际单位（Kg, m/s2)时规定K=1。那么就有；F=ma为了纪念牛顿，就把能使1kg物体获得1m/s2加速度的力称做一牛顿，用符号N表示问题：实际物体受力往往不止一个，多个力情况应该怎么办呢？平行四边形法则进一步引导学生得出牛顿第二定律更一般的表达式: F合=ma思考.讨论我们用力提一个很重的箱子，却提不动它。这个力产生了加速度吗？要是产生了，箱子的运动状态却并没有改变。为什么？
人教版新课标高中物理必修1时间和位移说课稿2篇
研究一种物理现象，总是要先从现象的描述入手。机械运动作为自然界最简单和最基本的运动形态，它所描述的是物体空间位置随时间变化的情况。因此，本节学习描述质点做机械运动需要时刻、时间间隔和位移等概念。相当一部分高一学生在具体过程中难以区别时刻和时间间隔。另外，由于思维的定式，在第一次接触既要考虑大小又要考虑方向的问题时，会因不适应造成学习困难。所以，区别“路程与位移”“时刻和时间间隔”是教学的重难点所在。学习这些内容的过程与方法对学习速度和加速度可以起到奠定基础的作用。教学的对象是高一的学生，这一时期的学生处在好奇善问、创新意识强烈的青少年期。对于生活中出现的各种现象具有浓厚的兴趣。但他们的思维还停留在简单的代数运算阶段，对于矢量和矢量运算的理性认识几乎没有。且对生活中出现的时间、时刻、时间间隔等不能做出很好的区分，对时常提及的路程、距离等形成了模糊的前概念。
人教版新课标高中物理必修1质点参考系和坐标系说课稿2篇
一、说教材《质点 参考系和坐标系》是人教版普通高中物理必修一第一章第一课的内容。本节课主要介绍了质点、参考系、坐标系的基本概念。通过本节课的学习为进一步学习后续课程起到了铺垫的作用。根据上述教材的结构和内容分析，又考虑到高一年级学生的认知结构及其心理特征，我制定了以下三维教学目标：1、知识与技能：知道质点的概念及条件；知道参考系的概念及作用；掌握坐标系的简单应用。2、过程与方法：促进学生自主学习，让学生积极参与、乐于探究、勇于实验、勤于思考，培养学生的科学探究能力。3、情感态度与价值观：通过质点 参考系和坐标系的学习，使学生了解生活与物理的关系，让学生学会用科学的思维去看待事物。根据普通高中物理课程标准，并在吃透教材的基础上，我确定了以下教学重点和难点：教学重点：质点概念的建立。只有掌握了这一点才能更加准确的理解和掌握后续教材的相关内容。

六、教学程序设计（“一三五”模式）为了完成这节课的教学目标，我是这样安排的：第一环节： （约10分钟）根据对自主探究案的批阅情况，解决学生的遗留问题具体实施：投影学生的自主探究案，让学生交流讨论，教师点评。第二环节： （ 约30分钟）新课学习：在“课堂互动案”的导学提纲引领下，完成这节课的三维教学目标。具体实施：多媒体辅助教学、交流讨论。第三环节： （约5分钟）课堂小结和布置作业：为了体现课程改革的新理念——学生是学习的主人，我改变传统的教师总结为学生总结的模式，既强化了学生所学的知识，又培养了学生的归纳和概括能力。作业分为两部分：（1）书面作业p85，1、2、3、4。（2）完成“应用提升案”。七、板书设计由于多媒体在物理教学中仅是一种辅助手段，不能完全取代黑板，因此一节课的主要内容和学生的必要参与还需要借助黑板来帮助。我在这节课的板书设计中突出了主要内容，简洁明了。
人教版新课标高中物理必修1自由落体运动说课稿2篇
学生回答的方法多样，让各小组根据自己讨论出来的方法对自己实验出来的纸带进行数据处理，并求出加速度，并且将多条纸带都进行处理，同时提醒学生对纸带的选择。接着，我会用多媒体展示重物下落实验打出来的纸带，用表格列出一段纸带上各点的瞬时速度，准确画出v-t图像，求出加速度，将结果给予学生的结果作对比，确定出正确结论。最后让学生分析总结：自由落体运动是初速度为零的匀加速直线运动，而且，多条纸带算出来的加速度的数值都接近相等，即加速度在实验误差允许范围内是相等的。引出重力加速度，介绍概念、方向及大小。（强调“同一地点”，让学生阅读教材中一些地点的重力加速度，可以了解重力加速度的大小与纬度有关，纬度越大加速度越大）。学习了重力加速度后让学生根据之前学习的匀变速直线运动公式推导出自由落体的运动规律。设计意图：让学生在学习过程中的主体地位和自主观能动性得到充分发挥，取长补短，培养了学生的实验操作能力，又使学生对自由落体运动的性质有深刻的印象，从而解决了本节课第二个难点。

The topic of this part is “Discover the reasons for festivals and celebrations.The Listening & Speaking & Talking part aims at talking about the experiences and feelings or emotions about the festivals and celebrations. This section aims at detecting the reason why the people celebrate the festivals, the time, the places, the types and the way of celebrations. It also explains why some traditions in the old celebrations are disappearing, like the firecrackers in the big cities and some new things are appearing like the prosperity of business or commerce. 1. Students can talk about what festivals they know and the reasons and the way of celebrating them.2. Students should learn the reading skills such as the headline and get the topic sentences, the structures of articles.3. Students can understand the past, the present situation of some festival around the world and why there are some changes about them. 4. Students can have the international awareness about the festivals.1. Students should learn the reading skills such as the headline and get the topic sentences, the structures of articles.2. Students can understand the past, the present situation of some festival around the world and why there are some changes about them.Step 1 Lead in---Small talkWhat festival do you like best ? Why ?I like the Spring Festivals because I can set off the fireworks, receive the lucky money and enjoy the Gala with my families.Step 2 Before reading---Pair workWhy do people celebrate different festivals ?The Spring Festivals is to celebrate the end of winter and the coming of spring and new life.The Mid-autumn Day is to celebrate the harvest and admire the moon.
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.
新人教版高中英语必修3Unit 1 Festivals and Celebrations-Reading for writing教学设计二
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.

The topic of this part is “Write about your festival experience”.During the Listening and Speaking and Talking, students are just asked to say out their festival experiences such as the Spring Festival, Mid-autumn Day, but this part students will be asked to write down their own festival experiences. During the reading part, it introduces the Naadam Festival in Inner Mongolia Autonomous Region, which can give students a good example to imitate. Students not only learn the festival, but touch and feel the Inner Mongolian’s character, the spirit and cultural atmosphere, which can help students form the cultural awareness and learn to enjoy and value the diversity of Chinese culture.Concretely, the dairy tells the experience that the author spent the Naadam Festival in Inner Mongolia Autonomous Region with his/her friend. The structure is clear. In the opening paragraph, it introduces the topic of the Naadam Festival and the whole feeling. Then it introduces the items of the festival like the ceremony, wrestling and horse racing. Finally, it summarizes this experience. Because this part is a travel journal, we must guide students pay more attention to these details: 1. use the first person. 2. use the past tense to tell the past thing and use the present or future tense to describe the scenery. 3. use the timeline to tell the development. 4. be careful for the author’s psychology, emotion and feeling, etc.1. Read quickly to get main idea; read carefully to get the detailed information about Naadam Festival.2. Learn the structure of the reading article and language.3. Write an article about a festival experience4. Learn to use the psychology, emotions and feeling in the writing.1. Write an article about a festival experience.2. Use the structure of the reading article and language.

This happens because the dish soap molecules have a strong negative charge, and the milk molecules have a strong positive charge. Like magnets, these molecules are attracted to each other, and so they appear to move around on the plate, taking the food coloring with them, making it look like the colors are quickly moving to escape from the soap.Listening text:? Judy: Oh, I'm so sorry that you were ill and couldn't come with us on our field trip. How are you feeling now? Better?? Bill: Much better, thanks. But how was it?? Judy: Wonderful! I especially liked an area of the museum called Light Games.it was really cool. They had a hall of mirrors where I could see myself reflected thousands of times!? Bill: A hall of mirrors can be a lot of fun. What else did they have?? Judy: Well, they had an experiment where we looked at a blue screen for a while, and then suddenly we could see tiny bright lights moving around on it. You'll never guess what those bright lights were!? Bill: Come on, tell me!? Judy: They were our own blood cells. For some reason, our eyes play tricks on us when we look at a blue screen, and we can see our own blood cells moving around like little lights! But there was another thing I liked better. I stood in front of a white light, and it cast different shadows of me in every color of the rainbow!? Bill: Oh, I wish I had been there. Tell me more!? Judy: Well, they had another area for sound. They had a giant piano keyboard that you could use your feet to play. But then, instead of playing the sounds of a piano, it played the voices of classical singers! Then they had a giant dish, and when you spoke into it, it reflected the sound back and made it louder. You could use it to speak in a whisper to someone 17 meters away.? Bill: It all sounds so cool. I wish I could have gone with you? Judy: I know, but we can go together this weekend. I'd love to go there again!? Bill: That sounds like a great idea!
