Unit 8 Detective stories Reading 教学设计 2025-2026学年译林版九年级（2012）九年级英语上册

该初中英语教学设计聚焦谋杀案相关词汇（如victim, suspect等）及案件细节（受害者背景、时间线、调查进展），通过展示犯罪新闻图片提问“警察如何破案”导入，搭建从生活经验到文本分析的支架，衔接词汇预习与略读扫读技能训练。 其特色是以模拟真实案件为情境，融合语言能力（词汇学习与阅读技能训练）、思维品质（小组分析证据推断凶手）、学习能力（个人写作“我的凶手推断”），如小组讨论“谁是凶手及证据”环节，既提升信息提取能力，又培养逻辑推理，助力学生主动建构知识，也为教师提供情境化教学范例。

Unit 8 Detective stories Reading 教学设计 I. Teaching Objectives 1. Knowledge Objectives Students will master vocabulary related to a murder case (e.g., victim, wound, guilty, suspect, witness, reward). Students will understand the details of the “Murder in West Town” case, including the victim’s background, crime timeline, and investigation progress. 2.

Prediction (5 Minutes) Look at the article title “25 - year - old Computer Engineer Murdered” and image. Ask: “What do you think the article will cover? Who might be involved?” Step 3 While - reading: Skim & Scan (11 Minutes) Skimming (3 Minutes) Students skim the article to identify main sections: victim info, crime timeline, investigation, suspect details. Check answers, discussing how headings and opening sentences outline the case. Scanning (8 Minutes) Part B1 & B2 (5 Minutes) Students scan to complete B1 (vocabulary definitions) and B2 (true/false questions about the case). Guide: Use key details (e.g., victim’s location, job, crime time). Discussion (3 Minutes) Share B2 answers. Discuss: “Why is the victim’s past important?

Group Deduction (3 Minutes) In groups, discuss: “Who do you think the murderer is? What evidence supports your deduction?” Step 5 Extension: Create Your Own Suspect (4 Minutes) Personal Writing (3 Minutes) Students write a short paragraph: “My Deduction of the Murderer” (explain who they think did it and why). Class Share (1 Minute) Volunteers share deductions, emphasizing evidence - based reasoning. Step 6 Summary & Homework (4 Minutes) Summary (2 Minutes): Recap the case details, key vocabulary, and deduction process. Homework (2 Minutes): Imagine you’re a detective. Write 3 questions you’d ask witnesses or the suspect to solve the case. IV. Assessment of Teaching Effectiveness Check B1, B2 for accurate vocabulary and detail extraction. Evaluate B3, B4 for clear analysis of the case and error correction. Assess personal writing for evidence - based deduction. V. Design Purpose Lead - in: Engage with crime - related media to introduce case analysis. Pre - reading: Build vocabulary to support comprehension of the murder case.
