Unit 4 Inventions-Section 4 Extending and developing competencies-Cross-curricular connection This unit, "Inventions", from the 2024 Shanghai Education Edition English textbook for Grade 8, focuses on the theme of inventions. The cross - curricular connection part aims to integrate English learning with other disciplines such as history, science, and art. Students will explore how inventions have shaped human history, the scientific principles behind them, and even the artistic inspiration related to inventions. By studying this unit, students can not only improve their English language skills but also gain a comprehensive understanding of inventions from multiple perspectives. 教学目标 Students will be able to use vocabulary related to inventions, such as "invent", "invention", "inventor", "discover", "creator", "innovation", "revolutionize", etc., accurately in context. They can master sentence patterns for describing inventions, like "The invention of... changed...", "It was invented by... in...", "This invention has had a great impact on...", and use them to express ideas about inventions. Students are expected to improve their reading comprehension ability of texts about inventions, being able to extract key information, understand the main idea, and analyze the structure of the passage. Develop students' writing skills by asking them to write a short passage about an invention, including its basic information, working principle, and influence. 教学重难点 1 Teaching Key Points Mastery of vocabulary and sentence patterns related to inventions. Understanding the historical background and basic scientific principles of common inventions. Ability to write a well - structured passage about an invention. 2 Teaching Difficult Points Integrating cross - curricular knowledge smoothly in English learning, for example, using English to accurately explain scientific principles. Helping students think critically about the impact of inventions on different aspects of society and express their views in English. 1 Vocabulary Invention - related nouns: invention, inventor, discovery, innovation, revolution, gadget, device, tool Verbs: invent, discover, create, innovate, revolutionize, develop, design Adjectives: innovative, revolutionary, useful, practical, convenient 2 Sentence Patterns "The invention of [invention name] is one of the most important events in [field/history]." "[Invention name] was invented by [inventor's name] in [time]." "This invention has made a significant difference to [people's lives/society/industry]." "Thanks to the invention of [invention name], we can now [describe the convenience brought by the invention]." 3 Historical and Scientific Knowledge Historical knowledge: The Industrial Revolution and its major inventions (steam engine, spinning jenny, etc.), the impact of these inventions on the transformation of society from an agricultural to an industrial one. Scientific knowledge: The principle of electricity and how it relates to the invention of electrical appliances (e.g., light bulbs, motors), the principle of the wheel and its importance in transportation. 教学过程 1 Lead - in (5 minutes) Show students some pictures of famous inventions, such as the wheel, the telephone, and the light bulb. Ask them to name these inventions in English and briefly describe what they know about them. Teacher: "Class, look at these pictures. Can you tell me the English names of these inventions? And do you know who invented them?" Students answer the questions, and the teacher gives positive feedback. 2 Knowledge Presentation (10 minutes) Vocabulary teaching: Present the new vocabulary related to inventions on the PPT. Explain the meaning, pronunciation, and usage of each word with examples. For example, when teaching "invent", the teacher can say, "Edison invented the light bulb. 'Invent' means to create or design something that has never existed before." Let students read the words aloud several times to practice pronunciation. Cross - curricular knowledge introduction: History aspect: Use a timeline to show the historical development of important inventions. For example, start from the ancient invention of the wheel, then introduce the inventions during the Industrial Revolution. Explain how these inventions changed the way people lived and worked at that time. "In the 18th century, the Industrial Revolution brought about many great inventions. The steam engine, invented by James Watt, revolutionized the manufacturing industry. Factories could now produce goods on a large scale, which led to the growth of cities and the change of the economic structure." Science aspect: Take the light bulb as an example. Use simple diagrams to explain the scientific principle of how a light bulb works. "When an electric current passes through the filament in the light bulb, the filament heats up and emits light. This is based on the principle of the heating effect of electric current." 3 Reading Activity (12 minutes) Provide students with a short passage about an invention (for example, the invention of the telephone). The passage should include information about the inventor, the historical background, the process of invention, and its impact. Ask students to read the passage quickly (skimming) to get the main idea and answer the following questions: "What is the passage mainly about?", "Who invented the telephone?", "When was it invented?" Then, let students read the passage carefully (scanning) to find detailed information and complete a table, such as filling in the columns of "Invention name", "Inventor", "Time of invention", "Scientific principle", "Impact on society". After that, ask several students to share their answers, and the teacher checks and corrects them. 4 Group Discussion and Presentation (10 minutes) Divide students into groups of 4 - Each group is assigned an invention (either a well - known one or an imaginary one). The task for each group is to discuss the following aspects in English: the basic information of the invention, the scientific principle behind it (if applicable), the historical background or the need that led to its invention, and its possible impact on society. They can also consider the artistic design of the invention if relevant. After the discussion, each group selects a representative to make a presentation to the whole class. The representative should use the vocabulary and sentence patterns they have learned to introduce the group's findings. During the presentations, other students listen carefully and can ask questions or give comments at the end. The teacher gives guidance and encouragement throughout the process. 5 Summary and Homework Assignment (8 minutes) Summary: Summarize the key points of this class with students, including the important vocabulary, the historical and scientific knowledge about inventions, and the main ideas from the reading and discussion. "Today, we have learned a lot about inventions. We know many new words related to inventions, and we also understand how inventions are related to history and science. We have discussed different inventions in groups and shared our ideas." Homework assignment: Ask students to write a short essay (about 100 - 120 words) about an invention they are interested in. They need to include all the aspects they have discussed in class, such as the inventor, the time of invention, the principle, and the impact. Suggest students to search for more information about an invention from other disciplines (history books, science magazines, or art - related websites) and be ready to share in the next class. 教学反思 Positive aspects: The use of pictures and real - life examples in the lead - in stage effectively attracted students' attention and activated their prior knowledge about inventions, which laid a good foundation for the following learning. The cross - curricular teaching method, integrating history and science knowledge into English teaching, made the class more interesting and rich. Students showed great enthusiasm when learning about the historical background and scientific principles of inventions while learning English. The group discussion and presentation activities provided students with a lot of opportunities to practice speaking English. They actively participated in the discussion, expressed their opinions, and improved their communication and cooperation skills. Areas for improvement: In the vocabulary teaching part, although examples were given, some students still had difficulty using the words accurately in sentences. In the future, more sentence - making exercises can be designed to strengthen students' understanding and application of vocabulary. During the group discussion, some groups spent too much time on non - key points, and the discussion was not very efficient. Next time, more specific guidance and time limits can be given to each group at the beginning of the discussion to ensure the quality of the discussion. In terms of the integration of art in the teaching process, it was not as in - depth as expected. In the future, more art - related materials, such as pictures of well - designed inventions or short videos about the design concept, can be introduced to better achieve the goal of cross - curricular connection with art. 2 / 37 学科网（北京）股份有限公司 学科网（北京）股份有限公司 $$
