Successfully used key terminology when prompted, demonstrating familiarity. 在提示下成功使用了关键术语，显示出熟悉度。

Written: 书面：

N/A (Lesson focused on oral review and concept explanation).

Student's Strengths 学生的优势

Good recall of basic macroeconomic definitions (e.g., Opportunity Cost). 对基本经济学定义（如机会成本）记忆力好。
Understands real-world implications, linking concepts like recession/COVID to the inward shift of the PPF. 理解现实世界的含义，将衰退/新冠疫情等与PPF向内移动联系起来。

Areas for Improvement 需要改进的方面

Needs deeper, independent reasoning for graphical analysis, specifically the economic reasoning behind PPF curvature. 需要对图形分析（特别是PPF弯曲背后的经济学原理）进行更深入的独立推理。
Could benefit from structuring arguments on the drawbacks of specialization more clearly (e.g., linking boredom directly to structural unemployment risk). 需要更清晰地构建关于专业化缺点的论点（例如，将工人厌倦与结构性失业风险更直接地联系起来）。

4. Teaching Reflection 4. 教学反思

Effectiveness of Teaching Methods 教学方法的有效性

Teacher effectively used retrieval practice to check prior learning on opportunity cost and PPF points. 老师有效地使用了检索练习来检查学生对机会成本和PPF点的先前学习情况。
The explanation of PPF curvature, although detailed, was necessary to ensure conceptual depth. 对PPF弯曲性的解释虽然详细，但对于确保概念深度是必要的。

Teaching Pace and Time Management 教学节奏和时间管理

The pace was slightly slow due to the necessary detailed review of PPF concepts, but this ensured the student was ready for new material. 由于需要详细复习PPF概念，课程节奏略慢，但这确保了学生已为新材料做好准备。
Good management by previewing the next topic (Functions of Money) without spending too much time on it. 通过预习下一个主题（货币职能）而不是花费过多时间，实现了良好的节奏管理。

Classroom Interaction and Atmosphere 课堂互动和氛围

Highly interactive and supportive. The teacher encouraged detailed explanations even when the student struggled, fostering a safe learning environment.

Ability to link complex theoretical concepts (like PPF curvature) back to real-world resource allocation (factor mobility). 能够将复杂的理论概念（如PPF弯曲性）与现实世界的资源配置（要素流动性）联系起来。

Effective Methods: 有效方法：

Using historical/famous examples (Ford, Adam Smith) to contextualize abstract economic theories. 使用历史性/著名案例（福特、亚当·斯密）来具体化抽象的经济学理论。
Probing follow-up questions (e.g., 'Why might we be at X on the PPF?') to test deeper understanding beyond rote memorization. 使用探究性的后续问题（例如，“我们为什么会在PPF上的X点？”）来测试超越死记硬背的深层理解。

Positive Feedback: 正面反馈：

Free Market vs. Command Economies (as they relate to allocation). 自由市场经济与指令性经济（与资源配置相关的）。

Specific Suggestions for Student's Needs 针对学生需求的具体建议

Graphical Analysis & Reasoning: 图形分析与推理：

Review the graphical shifts of the PPF (outward/inward) and practice articulating *why* the curve is concave using the concept of 'factor specialization' and 'increasing opportunity cost'. 复习PPF的图形移动（外移/内移），并练习使用“要素专业化”和“机会成本递增”的概念清晰阐述PPF内凹的原因。

Speaking & Communication: 口语与交流：

When explaining complex 'why' questions (like PPF curvature), try to structure the answer by breaking down the resource reallocation process step-by-step first. 在解释复杂的“为什么”问题时（如PPF弯曲性），尝试先分步骤拆解资源再分配过程，从而构建答案结构。

Concept Application: 概念应用：

Think about modern examples of structural unemployment caused by AI/technology, relating them back to the coal mining example discussed. 思考由人工智能/技术引起结构性失业的现代案例，并将其与讨论中的煤矿开采案例进行类比。

Recommended Supplementary Learning Resources or Homework 推荐的补充学习资源或家庭作业

Review the PPF diagram and ensure you can verbally explain why the curve is bowed out, focusing on factor specialization. 复习PPF图表，确保你能口头解释为什么曲线是内凹的，重点关注要素专业化。
Read ahead on the Functions of Money, especially considering why Bitcoin is currently debatable as a true store of value/medium of exchange. 预习货币职能，特别是思考为什么比特币作为真正的价值储存/交换媒介目前存在争议。
