Teaching Strengths 教学优势

Identified Strengths: 识别的优势：

Skillful scaffolding during the AD/AS diagramming, breaking down the abstract idea of 'potential' vs. 'actual' output. 在AD/AS图示过程中运用了高超的搭架技巧，分解了“潜在”与“实际”产出的抽象概念。
Effective probing during the long-form question to draw out student knowledge on external factors (e.g., questioning the link between tariffs and AD). 在长篇问答题中进行有效的探究，以引导学生了解外部因素（例如，询问关税与AD之间的联系）。

Effective Methods: 有效方法：

Using the analogy of personal potential (maths ability) to clarify why potential output cannot be less than current output in a negative output gap scenario. 使用个人潜力（数学能力）的类比来阐明在负产出缺口情景中，潜在产出不可能低于当前产出的原因。
Explicitly mentioning the AS exam structure relevance for short-answer questions, helping focus revision effort. 明确指出与AS考试结构相关的短问答题，有助于集中复习精力。

Positive Feedback: 正面反馈：

Teacher praised the student's grasp of exchange rate impacts: 'You're getting very good at your exchange rates. By the way, you're hot on that.' 教师表扬了学生对汇率影响的掌握程度：‘你在汇率方面做得非常好，顺便说一句，你在这方面很强。’
Positive reinforcement on calculation accuracy: 'Perfect,' 'Very good.' 对计算准确性的积极肯定：‘完美’，‘非常好’。

Next Teaching Focus 下一步教学重点

Reviewing positive output gaps and sustainable vs. unsustainable economic growth. 复习正产出缺口以及可持续与不可持续的经济增长。

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

Diagrammatic Representation: 图表表示：

When drawing output gaps, always label the LRAS line clearly as Potential Output, and the equilibrium point (E) as Actual Output. 在绘制产出缺口时，始终将LRAS线清晰地标记为潜在产出，将均衡点（E）标记为实际产出。
Practice differentiating between shifts in AD/AS (growth) and movements along the curves (changes in price level/output due to existing AD/AS). 练习区分AD/AS的移动（增长）和曲线上的移动（由于现有的AD/AS导致的物价水平/产出变化）。

Essay & Structure: 论文与结构：

For 5-mark questions on growth factors, structure the answer by grouping factors (e.g., Supply-side constraints, Demand-side shocks, External factors) before detailing the links. 对于关于增长因素的5分问题，在详细说明联系之前，将答案按因素分组（例如，供给侧制约、需求侧冲击、外部因素）。
Continue to actively link concepts like tariffs, exchange rates, and government spending, as this demonstrates higher-level synthesis required for top marks. 继续积极联系关税、汇率和政府支出等概念，这展示了获得高分所需的高级综合能力。
