The Monarch’s Journey
Every autumn, millions of monarch butterflies leave Canada and the northern US and travel up to 4,000 km to the warm forests of central Mexico. Unlike birds, no single butterfly finishes the whole trip. Instead, the journey is completed by four generations. The great-grandparents that leave Canada will never see Mexico; it is their great-grandchildren that finally reach the oyamel fir trees. Even more surprisingly, the last generation returns north in spring. How do they know the way? Scientists once thought they followed rivers or mountains, but lab tests show that monarchs have a built-in “sun compass” and can also sense the earth’s magnetic field. Yet climate change and illegal logging are destroying the very forests that shelter them.

2. 教学目标
────────────────
After the lesson, students will be able to
a. 认知:梳理并整合monarch迁徙路线、代际接力、导航机制、生存危机四类信息;
b. 技能:运用“四层级问题框架”(字面—推理—评价—创新)自主设计高质量阅读问题;
c. 情感:体悟“微小生命—宏大旅程”的张力,形成对生态保护的共情与责任意识。
────────────────
3. 教学流程(含问题链)
────────────────
Step 1 情境导入 3 min
教师展示 10 秒延时摄影:monarch 群飞。
T 提问(示范 Level-1 字面):
Q1. Where do the butterflies start their journey?
学生快速浏览首段找答案 → Canada & northern US.
Step 2 教师示范提问 7 min
T 板书“四层级”并用同一语篇示范:
Level-1 Literal: How far is the trip? (4,000 km)
Level-2 Inferential: Why does the writer say “no single butterfly finishes the whole trip”?
Level-3 Evaluative: Does the word “great-grandparents” make the journey more impressive? Why?
Level-4 Creative: If you were a scientist, what further experiment would you design to test their “sun compass”?
→ 学生用符号 ★/△/○/◇ 在文本边注标记四层级。
Step 3 同伴共建问题库 12 min
四人小组,每人先独立写 1 个 Level-2 或 Level-3 问题(写在便利贴);
组内用“问题质量检核表”互评:
• 与文本信息相关?
• 需要更高阶思维?
• 表述清晰?
每组把通过检核的 2 个最佳问题贴到黑板“问题墙”,形成全班共享库(预计 6-8 个问题)。
【教师巡视,对薄弱组提供支架:可参考动词提示—infer, explain, justify, predict, evaluate…】
Step 4 全班共探 10 min
教师选取 3 个学生问题现场研讨:
例 S-Q1 (Level-2): How does the writer’s use of numbers help readers understand the difficulty of the journey?
例 S-Q2 (Level-3): Is the monarch’s built-in compass a result of evolution or something else? Justify.
• 先 30 秒静默,再 Think-Pair-Share
• 教师串联文本 evidence → 迁移到人类科技(GPS vs. 生物导航)。
Step 5 独立提问·迁移任务 5 min
学生在便利贴再写 1 个 Level-4 创新问题,贴到“Wonder Wall”。
课后任务:任选 1 个同学的问题,用 100 词英语书面回答,下节分享。
Step 6 评价与反思 3 min
Two stars and a wish: 学生给同伴提问打 2 个亮点 + 1 条改进建议。教师拍照上传班级 Padlet,形成可回溯的“问题成长档案”。
────────────────
4. 学情支架
────────────────
• 语言:提供导航类词汇云图(compass, magnetic field, generation, route…);
• 思维:张贴“动词梯”——describe → explain → evaluate → create;
• 情感:播放 30 秒墨西哥 oyamel 森林被砍伐前后对比短片,激活情感锚点。
────────────────
5. 板书(示例)
────────────────
The Monarch’s Journey
Four-level Questions
Level-1 Literal ★
Level-2 Inferential △
Level-3 Evaluative ○
Level-4 Creative ◇
────────────────
6. 可能生成的学生问题(供教师预案)
────────────────
Level-2: What can we infer from the phrase “great-grandchildren that finally reach…” about the lifespan of monarchs?
Level-3: Does the author succeed in arousing readers’ sense of urgency? How?
Level-4: If the monarchs lost their magnetic sense, how would it affect the food web in Mexico?
────────────────
7. 课后延伸
────────────────
观看 5-min BBC Earth 片段《Monarch Migration》,用今天框架再提 2 个新问题,下一节“Reading for Writing”课将用于信息整合写作。
