Unit 4 Inventions-Section 3 Expressing and communicating ideas-Writing This section of Unit 4 Inventions focuses on writing. It aims to guide students to design and introduce their own inventions, helping them develop innovative thinking and writing skills. Students will learn to describe the appearance, functions, features, and advantages of an invention. By using a model essay and mind maps, they can structure their writing and express their ideas clearly. The writing task is closely related to real - life situations, such as the school science festival, which can stimulate students' interest in writing. 教学目标 Students can master the key words and phrases related to inventions, such as "solar power", "top speed", "instead of", etc. Students are able to understand and use the language strategies for introducing inventions, like using comparative forms, data support, and conjunctions. 教学重难点 Guide students to use the knowledge learned in this unit, with the help of model essays and mind maps, to sort out writing ideas and content, and write a passage to introduce their inventions. Enable students to use appropriate language to describe the appearance, functions, features, and advantages of inventions. Train students to use self - assessment and peer - assessment to improve their writing. 1 Key Words and Phrases solar power: Energy from the sun. For example, "This new invention uses solar power, which is clean and renewable." top speed: The maximum speed that a vehicle or machine can reach. "The car has a top speed of 200 km/h." instead of: In place of. "We use electric energy instead of petrol in this new vehicle." in a shorter time: In a briefer period. "With this invention, we can finish the work in a shorter time." on land: On the ground. "This vehicle can not only fly in the air but also run on land." turn into: Change into. "The small device can turn into a useful tool in seconds." in the future: At a later time. "I believe this invention will be widely used in the future." 2 Language Structures Comparative forms: To compare the features or functions of an invention with others. For example, "This new mobile phone is more convenient than the old one as it has a larger screen and faster charging speed." Data support: Use specific numbers to describe the performance or characteristics of an invention. "The new printer can print 50 pages per minute, which is much faster than the previous model." Conjunctions: Such as "and", "but", "so", "because" to connect different parts of the description and make the writing more logical. "The invention is small in size, but it has many functions. Because it is portable, it is very popular among people." 教学过程 1 Lead - in (5 minutes) Show some pictures of interesting inventions, such as smartwatches, 3D printers, and self - driving cars, on the PPT. Ask students: "What are these? Do you know how they work? Which one do you think is the most useful? Why?" Let students discuss in pairs for 2 minutes and then invite some pairs to share their ideas. This activity can arouse students' interest in inventions and lead to the writing topic of this class. 2 Task Introduction (3 minutes) Set the context: "Our school is going to hold a School Science Festival soon, and it is now collecting invention ideas from all students. Your task today is to write an English article to introduce your own invention." Present the writing requirements on the PPT: Clearly introduce what your invention is. Describe its appearance, main features, functions, and advantages. Use at least three key words or phrases and one language structure we learned in this unit. The article should be about 100 - 120 words. 3 Pre - writing (12 minutes) Group discussion: Let students discuss in groups of four about the inventions they want to design. Guide them to think about the following questions: What problem do you find in your daily life? (For example, traffic jams, waste of time on doing chores, etc.) Who needs help with this problem? (Students, office workers, the elderly, etc.) What are the possible ways of solving this problem? (Design a new transportation, a labor - saving device, etc.) Each group chooses a recorder to write down the main ideas of the discussion. After 5 minutes, invite some groups to share their discussion results. Reading and learning from a model essay: Show Wang Yao's invention - a flying car on the PPT. Let students read the article about it quickly and predict the content of each paragraph by asking questions like: "What does a flying car look like? What main features does a flying car have? What can a flying car do? How does a flying car work? What benefits can a flying car bring to us?" Then, let students read the article carefully and match the key points in the mind map with each paragraph. The key points in the mind map are: What it is, What it looks like, Main features, What it can do, Benefits. After that, use a question chain to help students complete the mind map of "A flying car" and sort out the writing framework: Q1: What is Wang Yao ’s invention? Q2: What are the main features of her invention? Q3: What does it look like? Q4: What can each part of the invention do? Q5: What can the invention do? Q6: What are the benefits of the invention? Analyze the language used in the model essay together, such as the use of comparative forms, data support, and conjunctions, and let students underline the key words and useful sentences. 4 While - writing (15 minutes) Students start to write their own articles according to the mind map and the writing requirements. They can refer to the model essay and the words and sentences they underlined. Walk around the classroom and offer help when students have difficulties in writing, such as grammar mistakes, vocabulary usage, or logical problems. Encourage students to use their imagination and be creative in their writing. 5 Post - writing (5 minutes) Self - assessment: Distribute the self - assessment form to each student. The form includes items such as whether the content meets the requirements, whether the key words and language structures are used correctly, whether the grammar and spelling are correct, and the overall quality of the writing. Let students check their own articles according to the form and make some corrections. Peer - assessment: Pair up students. Each student exchanges their writing with their partner. They read each other's articles and fill in the peer - assessment form, which has similar items to the self - assessment form. They also need to write down some suggestions for improvement. After peer - assessment, students get their own articles back and make further improvements according to their partners' suggestions. 6 Summary and Homework Assignment (5 minutes) Summarize the key points of this class: how to design an invention, how to use mind maps to write, and how to conduct self - assessment and peer - assessment. Assign homework: Students need to rewrite their articles neatly and hand them in next class. Ask students to search for more information about famous inventions on the Internet and make a simple poster about one of them, introducing its inventor, invention time, and influence. 教学反思 Positive aspects: The lead - in part with interesting invention pictures can effectively arouse students' interest and enthusiasm, making them quickly involved in the class. Group discussion provides students with an opportunity to exchange ideas, which can inspire their creativity. Most students actively participated in the discussion and came up with some interesting invention ideas. The teaching process from pre - writing to post - writing is clear and step - by - step. The model essay and mind map play a good guiding role, helping students master the writing method and structure. Self - assessment and peer - assessment can improve students' awareness of self - correction and the ability to evaluate others' works. Areas for improvement: Some students still have difficulties in using complex sentence structures and accurate vocabulary to express their ideas, which indicates that more grammar and vocabulary training are needed in future teaching. In the group discussion, a few students dominated the conversation, while some students participated less actively. In future group activities, more attention should be paid to ensuring the full participation of each student. The time for writing and assessment is a bit tight. Some students may not have enough time to fully complete their writing and make in - depth assessments. It is necessary to adjust the time allocation in future teaching to ensure better teaching effects. 2 / 37 学科网（北京）股份有限公司 学科网（北京）股份有限公司 $$
