Unit 4 The Internet Connects Us Lesson 23: The Internet — Good or Bad? I. Teaching Objectives By the end of the lesson, students will be able to: Extract pros and cons of the Internet from the text to complete tasks (table - filling, dialogue - ticking), aligning with High school entrance examination reading comprehension skills. Master target vocabulary (e.g., advantages, disadvantages, harmful, social) and use them to discuss Internet impacts, preparing for High school entrance examination vocabulary tasks. Understand the dual nature of the Internet (benefits like efficiency, risks like overuse) and analyze responsible Internet - use strategies, supporting High school entrance examination - style thematic analysis of technology. Collaborate in groups to evaluate Internet activities for junior high students, enhancing High school entrance examination critical - thinking and oral - communication skills. II. Key Points & Difficulties Key Points Internet Pros & Cons: Pros: Easier life (homework, communication), global connections. Cons: Harmful overuse (health, social isolation), cyber risks (hacking, personal - info theft). Vocabulary & Phrases: advantages, disadvantages, harmful, social, properly, carefully; Phrases: every coin has two sides, stay in touch. Difficulties Balancing pros and cons in discussion (e.g., “Internet helps study but overuse harms health”). Explaining responsible Internet - use strategies (e.g., “Use carefully, avoid strangers online”). Evaluating Internet activities (e.g., “Which are safe for students? Why?”) with clear reasoning. III. Teaching Methods Task - Based Learning (TBL): Through text - analysis tasks (table - filling, dialogue - ticking), vocabulary practice, and group evaluation of Internet activities. Pros - Cons Debate: Structured discussion to unpack Internet duality. Collaborative Learning: Group work for activity evaluation, emphasizing peer feedback on reasoning and vocabulary use. IV. Teaching Aids CAI (Internet - pros - cons animations, vocabulary - definition slides, activity - evaluation templates). Textbook, worksheets, and “Internet - Impact Cards” (illustrating pros/cons for discussion). V. Teaching Procedures Step 1: Warm - up – Parents’ Internet Worries (5 mins) Discuss the THINK ABOUT IT questions: Why are some parents worried about kids using the Internet? (E.g., “Worried about overuse, strangers, or harmful content.”) Does the Internet make life simpler? How? (E.g., “Yes—chat with friends, do homework online.”) Share: Invite 3–4 students to share. Write down keywords: Internet, parents, worries, pros/cons. Step 2: Pre - reading – Vocabulary & Prediction (8 mins) Vocabulary Introduction: Teach words with examples: advantages: “Internet advantages: fast homework, global connections.” disadvantages: “Disadvantages: overuse, cyber risks.” harmful: “Spending too much time online is harmful to health.” social: “Overuse makes people less social with family.” properly/carefully: “Use the Internet properly to avoid risks.” Idiom Highlight: “Every coin has two sides” (pros and cons exist). Prediction: Ask: What pros/cons will the text mention? How to use the Internet responsibly? Step 3: Reading – Pros & Cons Extraction (12 mins) Complete Let’s Do It! 1 (Table - Filling): Answers: Good things: Makes life easier (homework, communication), global connections, fast information. Bad things: Harmful overuse (health, social isolation), cyber risks (hacking, info theft). Text - Structure Analysis: Sections: Pros (easier life) → Cons (overuse, cyber risks) → Responsible - use advice. Pros - Cons Debate Starter: Use “Internet - Impact Cards” to discuss: “Is the Internet more good or bad? Why?” (E.g., “More good—helps study, but needs careful use.”) Step 4: Vocabulary & Dialogue Practice (10 mins) Complete Let’s Do It! 2 (Dialogue - Ticking): Answers: ☑ Their school project (vs. homework). ☑ Chat with friends easily (vs. TV programs). ☑ Properly and carefully (vs. freely). Sentence Expansion with Vocabulary: Practice: “The Internet has advantages (chatting) but needs careful use. Li Ming thinks we should use it properly to avoid disadvantages (harmful overuse).” Responsible - Use Discussion: Explain: “Properly = follow rules; carefully = avoid risks (strangers, overuse).” Step 5: Group Project – Internet Activity Evaluation (15 mins) Task Introduction: Activity - Evaluation Template: Activity: ____________________ Safe for students? ☑ Yes / ☐ No Reason: ____________________ (e.g., “E - mail with family is safe; chatting with strangers is risky.”) Example: “Activity: E - mail with friends. Safe: Yes. Reason: Trusted contacts, no strangers.” “Activity: Chat online with strangers. Safe: No. Reason: Risk of harmful interactions.” Group Work: Students evaluate activities, fill in the template, and prepare a 3 - minute presentation. The teacher guides reasoning (e.g., “Why is ‘downloading documents from strangers’ unsafe?”). Class Sharing: Groups present evaluations. Feedback focuses on: Clear reasoning and vocabulary accuracy (e.g., harmful, social, properly). Feasibility of safety advice (e.g., “Avoid strangers online to stay safe”). Step 6: Summary & Homework (5 mins) Summary: Recap Internet pros/cons, responsible - use strategies, and activity - evaluation key points. Homework: （1）Write a 6 - sentence paragraph: “The Internet—Good or Bad?” (use 3 key terms: advantages, harmful, carefully). （2）Create a “Responsible Internet - Use Poster” with 3 rules (e.g., “No chatting with strangers”).
