Unit 12 Innovation Topic Talk 教学设计-2024-2025学年高中英语北师大版（2019）选择性必修第四册

附件： 教学设计 课程基本信息 课题 Unit12 Innovation 课型 新授课 学科 英语 年级 高二 学段 普通高中 版本章节 第二节 Topic Talk 教学目标 1. Master core vocabulary (e.g.innovation, creative, inspire) and topic-related sentence patterns; understand the text’s main idea and logical structure. 2. Communicate fluently about innovation topics in English (e.g.share creative ideas). 3. Cultivate innovation awareness and appreciate the value of creative thinking. 教学重难点 Key Points: Master topic-related vocabulary/sentence patterns; comprehend the text's core content. Difficult Points: Express in-depth, logical opinions on innovation in English; analyze the text’s implicit logical structure. 学情分析 Senior 2 students have basic English vocabulary and reading skills to understand topic-based texts. However, they lack vocabulary related to "innovation" and may struggle to express in-depth views on this topic in English. 教学准备 Multimedia resources: PPT courseware with innovation cases (e.g., creative products, technological inventions), English short videos (showcasing innovative practice. Teaching tools: Core vocabulary cards (e.g., innovation, creative), group discussion task sheets. 教学过程 教学任务 教学内容 设计意图 创新设计（含 AI 应用） Lead-in Concept Introduction 1. Display AI-generated contrast images (e.g., compass vs. penicillin, smartphone vs. gravity) to guide students to discuss and distinguish "invention" and "discovery"; 2. Introduce the four ancient Chinese inventions as classic examples; Summarize formal definitions: "Invention \create new things; Discovery \ recognize existing things". 1. Activate students’ prior knowledge of innovation-related concepts; 2. Clarify the core difference between "invention" and "discovery" through visual comparison; 3. Arouse interest in the topic with cultural examples. 1. Use AI image generators (e.g. Mid Journey) to create customized contrast images (labeled "AI-Generated") to avoid generic textbook pictures; 2. Embed AI voice prompts (e.g., "Which one is an invention? Think and share!") to guide discussion rhythm. Vocabulary & Sentence Preparation 1. Review key words in the PPT(e.g., "grand", "brilliant", "influential", "theoretical") with AI-generated scenario sentences (e.g., "The brilliant invention of paper-making had an influential impact on culture"); 2. Practice topic-related sentence structures: "____ is an invention/discovery that improves human life because ____". 1. Help students master topic vocabulary and its practical usage; 2. Build language scaffolding for subsequent listening and discussion. 1. Use AI vocabulary tools (e.g., Quiz let AI) to generate context-based sentences matching students’ English proficiency; 2. Design AI interactive flashcards (with pronunciation check function) for quick memory drills. Listening Practice (Text Builder) 1. Guide students to read the Text Builder in advance (focus on "Inventor's Interests and Qualities", "Types of Inventions"); 2. Play the AI-adjusted listening material (speed adjustable for different levels); Ask students to underline heard words/expressions to complete the Text Builder; 3. Check answers with real-time AI feedback. 1. Train students’ ability to listen for general and specific information; 2. Help students understand the characteristics of inventors and types of inventions; 3. Improve listening comprehension in innovation-themed contexts. 1. Use AI audio tools (e.g., Eleven Labs) to adjust the listening material’s speed/tone (labeled "AI-Adjusted Listening") to fit the class’s overall level; 2. Use AI grading tools (e.g.Spring) to scan students’ completed Text Builder and give instant feedback (e.g., "Correct! 'Creative' and 'curious' are key qualities"). Oral Discussion (Pair Work) 1. Assign pair work: "Discuss 2 questions: ① What inventions/discoveries are significant for human well-being? ② What invention can you not live without? Why?"; 2. Invite 3-4 pairs to present their ideas; 3. Comment on students’ expressions (focus on vocabulary accuracy and logic). 1. Improve students’ oral fluency in discussing innovation topics; Encourage students to connect knowledge with daily life; 2. Cultivate collaborative thinking through pair work. 1. Provide AI virtual discussion partners (e.g., Chat GPT) for shy students: the AI can ask follow-up questions (e.g., "Why can’t you live without mobile phones?"); 2. Use AI speech analysis tools to give brief feedback on presentations (e.g., "Good use of 'significant'! Try adding one more reason"). Summary 1. Summarize the lesson: core concepts (invention vs. discovery) + listening/oral key points; 1. Consolidate the lesson’s key knowledge; 2. Train students’ ability to express personal views in written form; 3. Extend the topic to real-life reflection. 1. Use AI mind map tools (e.g. Mind AI) to generate a visual summary (labeled "AI-Generated Lesson Map") showing the logical connection between "concepts → listening → discussion"; 作业设计 1. Assign homework: Write a short paragraph titled "How My Life Would Be Different Without ____ (an invention)"; 2. Provide AI writing scaffolds (e.g., "First, introduce the invention; Then, talk about its functions; Finally, describe life without it" 板书设计/课堂小结 Unit12 Innovation Lesson1 Topic Talk 【Core Concepts】 Invention→ Create new, non-existent things e.g., smartphone / paper-making(Visual: AI-generated contrast image)- Discovery→ Identify already existing things. e.g., gravity / penicillin(Visual: AI-generated contrast image) 【Key Language】 Vocabulary:innovation | creative | inspire | influential | brilliant. Sentence Pattern:“____ is an [invention/discovery] that improves human life because ____.” Class Summary In today’s Lesson1 Topic Talk (Unit12: Innovation): 1. We clarified the core distinction between invention (creating new things) and discovery (recognizing existing things), supported by AI-generated contrast images. 2. We mastered innovation-themed vocabulary and sentence patterns via AI-customized examples and interactive flashcards. 3. We practiced listening (with AI-adjusted audio speed) and oral discussion (paired with AI virtual partners to boost engagement). 4. Homework: Write a paragraph “How My Life Would Be Different Without an Invention” (AI writing scaffolds provided.) 教学反思 Teaching Reflection Strengths: 1. AI tools (e.g., Chat GPT as discussion partners, Quiz let AI for vocab drills) significantly increased engagement—even quiet students participated actively. 2. AI-adjusted materials (e.g., level-matched listening speed, personalized tasks) fit diverse proficiency levels, ensuring most students kept pace. Areas for Improvement: 1. A few students struggled to operate AI tools (e.g.accessing Quiz let flashcards), slowing their learning briefly. 2. AI’s oral feedback was too general; it lacked specific suggestions (e.g.lexical/structural tweaks) for students’ expressions. 3. Future Adjustments: Add a 2-minutes mini-tutorial for targeted AI. Customize AI feedback to include detailed comments. (e.g. "Use 'influential' instead of 'very useful' to fit the topic"). 学科网（北京）股份有限公司 $
