Students will learn how to give simple English commands (prompts) to an AI tool to create a picture that matches their writing. 3. Students will learn to use a mind map to plan their ideas before they start writing. 教学内容 Key Points： 1. Using the new words and sentences to talk about a sport (what it is, how often they do it, and why they like it). 2. Using a mind map to organize their ideas for the post. Difficult Points： 1. Thinking of the right English words to describe the picture they want the AI to create. 2. Making sure the picture created by the AI really fits the story in their writing. 教学过程 Step 1: Lead-in & Warming up 播放一段1分钟短视频，包含跑步、游泳、打球等多种运动场景。 视频链接：https://v.douyin.com/sVWNHq_MD-Y/ (视频播放结束，教师微笑出镜) T: "Hello, everyone! Welcome to our class. That was a cool video, wasn't it? It's all about keeping fit."? T: "So, how do you keep fit? Today, we're going to explore different ways that teenagers keep fit and learn how to share our own favorite ways." 设计意图:视频导入，直观生动，迅速抓住学生注意力，激发学习兴趣，自然引出本课话题“Keep Fit”。 Step 2: Reading for Information "First, let's meet three students and find out their ways to keep fit. Please look at page 22, activity 1b.” 屏幕显示： 展示教材1b部分，清晰呈现Xia Tian, Jenny, Steve三人的文本和图片。 T:"I will read about Xia Tian. While listening, please find out: What is his sport and why does he like it?" (教师用清晰、有感染力的声音朗读Xia Tian的段落)。 T: I like skateboarding very much. My friends and I practice at a special park twice a week. My skateboard is really cool, and so are theirs. We encourage one another to do tricks. Some tricks are difficult, but once you succeed, you feel great! I like skateboarding because it keeps me fit. T: "Now, who would like to be our reader for Jenny's part? Please read it for us."。 S：This year, my goal is to be really fit. I jog, swim, and do sit-ups. But my favorite way of keeping fit is to use an exercise app to work out. The app gives me exercises to do every day. It can show my progress. My friends use the app too. We have fun when we keep fit together. T: "Thank you. That was great. And how about Steve? Any volunteer?" S: I'm in my school's baseball club, so I paly baseball quite often. It's my favorite sport. We play many matches. The other teams are great, but I think ours is the best! We usually practice three times a week after school. We also exercise a lot because it keeps us fit and helps us play better. Baseball also builds team spirit. All of us are good friends, both on and off the field. We work as a team, and we win or lose as a team. 设计意图：通过师生接力朗读，既能为学生提供正确的语音示范，又能给予学生参与和展示的机会，增强课堂互动性，锻炼学生的朗读能力。。 T:"Now we know their ways. Let's work together to complete the table in 1c. How often does Xia Tian do it? And why does he like it?" (教师提出问题，留出几秒思考时间)。 屏幕显示： 出现1c的表格。 S：“Xia Tian practices twice a week. He likes it because it keeps him fit and he feels great when he succeeds.” T:(教师在屏幕上的表格中填入答案) "Exactly! Now for Jenny and Steve." (用同样的方式，引导学生回答，快速完成表格填写)。 屏幕显示： 完整的表格： Name How often he/she does it Why he/she likes it Xia Tian twice a week It keeps him fit; he feels great. Jenny every day She can see her progress. Steve three times a week It's his favorite sport; it builds teamwork. 设计意图： 任务驱动，聚焦关键信息提取。学生作答，既能示范标准答案，又能保持课程节奏。 Step 3: Model Analysis & Skill Building T:"Excellent job! We've learned how to get information. Now, how can we write about our own favorite sport? Let's learn from a model. Look at Kate's post." 屏幕显示： 展示2a中Kate的帖子和下方的空白思维导图。 T:"A mind map is a great tool to organize our ideas before writing. Let's fill it in for Kate." T: "What's Kate's favorite sport or exercise?" S: "Swimming!" T: "What does she like about it?" S: "It's fun, and the cool water feels great." (教师填入思维导图对应分支)。 T: "How often does she do it?" S: "two or three times a week" (教师填入)。 T: "And why is it good for her?" S: "keeps me healthy", "good exercise for my body" (教师填入)。 屏幕显示： 一个完整清晰的关于Kate的思维导图。 T:"See? With this mind map, the structure of the post is very clear! This is the key to writing a good post." 设计意图： 重点讲解思维导图这一“学习方法”，将隐性的写作思路显性化、结构化，为学生后续的写作任务搭建清晰的脚手架。 Step 4: AI-Powered Creation T: "Now for the most exciting part! We will create our own post, with text and a picture, just like Kate's. And we'll use a magical tool - an AI Art Assistant!" 屏幕显示: 界面切换，左边是教师的思维导图和写好的短文， T: "First, I made my own mind map about jogging and wrote my post." 屏幕显示: 左侧展示教师的文本： My favorite sport is jogging. I enjoy listening to music while I run. I usually jog four times a week. It makes me feel fit and energetic. T: "This is my text. But a post needs a cool picture! Let's ask the AI to draw one for me. To do that, we need to give it instructions in English. We call this a 'prompt'." T: (教师放慢语速，进行“提示词思维”教学) "How can I describe the picture I want? Let's look at my text for keywords." (PPT显示 jogging, music, energetic). "So, my prompt should include these ideas. I want a picture of... a teenage girl, who is jogging, she looks happy and energetic, maybe in a park, and she is listening to music. Let's try this prompt:" 屏幕显示文稿: A happy teenage girl with a ponytail, jogging in a sunny park, wearing headphones, full of energy, anime style. T：Adding 'anime style' can make the picture more fun！ T: "Ready? Let's see the magic!"。 屏幕显示: T: "Wow! Look at the amazing pictures! It’s created by AI from our words. I like it." （示例图） 屏幕显示: 图片在文本旁边，形成一个完整的、图文并茂的帖子。 T: "Perfect! Now I have my own unique post with text and a picture created by AI. Isn't that cool? You can turn your words into art!" 设计意图：它将语言学习从纯文本扩展到多模态创作，教学重点从“写什么”提升到“如何用英语创意地表达和指挥AI”。这个过程极具趣味性和启发性，能极大激发学生的学习动机。 Step 5: Summary & Assignment T: "Time flies! Today, we've learned to talk about keeping fit. More importantly, we learned a super skill: how to use a mind map to plan our writing, and how to use English prompts to create pictures with AI!" 屏幕显示： 总结要点： Talk about exercise: What? How often? Why? Use a Mind Map to plan your text. Use English Prompts to create your picture! T: "For your homework, please create your own post. First, make a mind map. Second, write your text. Finally, try to use an AI image tool to create a picture for your post. Be a creative writer and an AI artist!" T: "That's all for today. Keep fit, keep creating! See you next time. Bye-bye!" 学科网（北京）股份有限公司 $
