人教版高中生物必修3第四章第二节《种群数量的变化》说课稿
4、种群数量变化的其他类型我结合“种群数量下降”这个知识点对学生进行寓教。现今的自然界，许多野生生物种群的数量都在下降，为什么呢？我提供了世界人口近2000年的种群增长曲线，一切都在不言而喻中。现今社会的主题是呼吁建立和谐社会，作为生物老师，我想它不应该仅仅指人与人之间的和谐，也不应该仅仅指人与社会之间的和谐，它更应该昭示着人与自然之间的和谐，人类只有学会与自然和谐相处，才能在生物圈中享受最大的幸福。6、小结课程在实验的大背景下展开，也在实验的背景中结束，这里可以呈现出一个完整的探究思路。同时，学生思考如何实现多种预期过程，相当于对本课进行小结。五、效果预测课堂上选取的内容基于学生的生活体验，创设的情境能激发学生的兴趣，设置的问题符合学生的认知水平，有助于学生能力的提高，教学目标可以基本实现。
《一个消逝了的山村》说课稿 2021—2022学年统编版高中语文选择性必修下册
这几段内容传达出的是“要敬畏生命，尊重生命；更要敬畏大自然，尊重大自然，爱护大自然”的主旨内涵，因此让学生通过自由朗读的方式，再次体会冯至对这个消逝了的山村的细致的美好的描绘，感悟冯至传达出的对生命，对自然的理解和思考。5.最后一个自然段的解读依然是交给学生，先齐读课文，再让学生自主分享自己的体会或疑惑。但在这一环节我也设计了两个我认为必须解答的两个问题，一是怎么理解“在风雨如晦的时刻”；二是“意味不尽的关联”是指什么。我认为这两个问题一个涉及到写作背景，一个涉及到对全文主旨的一个整体把握，能够进一步帮助学生理解散文的深刻内涵和主旨，让学生有意识的在阅读散文过程中通过背景知识进行理解。既尊重学生的个性化解读，又能够让学生有意义学习，完成预设的教学目标。如果学生没有提到这两处，那我就需要做出补充。
古诗词诵读《桂枝香?金陵怀古》说课稿（一） 2021-2022学年统编版高中语文必修下册
王安石，字介甫，号半山。北宋著名政治家、思想家、文学家、改革家，唐宋八大家之一。欧阳修称赞王安石：“翰林风月三千首，吏部文章二百年。老去自怜心尚在，后来谁与子争先。”传世文集有《王临川集》、《临川集拾遗》等。其诗文各体兼擅，词虽不多，但亦擅长，世人哄传之诗句莫过于《泊船瓜洲》中的“春风又绿江南岸，明月何时照我还。”且有名作《桂枝香》等。介绍之后设置这样的导入语：今天我们共同走进王安石，一起欣赏名作《桂枝香·金陵怀古》。(板书标题)(二)整体感知整体感知是赏析文章的前提，通过初读，可以使学生初步了解将要学到的基本内容，了解文章大意及思想意图，使学生对课文内容形成整体感知。首先，我会让学生根据课前预习，出声诵读课文，同时注意朗读的快慢、停顿、语调、轻重音等，然后再播放音频，纠正他们的读音与停顿。其次，我会引导学生谈谈他感受。学生通过朗读，能够说出本词雄壮、豪放、有气势，有对景物的赞美和对历史的感喟。

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.

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!
