📚 Year 7 WJEC Economics: Key Points for Practical Assessments | 七年级WJEC经济：实验/实践考核要点
In Year 7 WJEC Economics, practical assessments are designed to let you explore basic economic ideas through hands‑on tasks. You might survey classmates about their spending, run a mini‑market stall, or simulate how prices change. These activities build skills you will need for later study, while making abstract concepts – like scarcity, choice, and demand – real and memorable.
在七年级WJEC经济课程中，实践考核旨在通过动手任务让你探索基本的经济学概念。你可能会调查同学们的消费情况、经营一个迷你市场摊位，或模拟价格如何变化。这些活动既为你今后的学习打好技能基础，也让稀缺、选择、需求等抽象概念变得真实而难忘。
1. Understanding the Purpose of an Economics Practical | 理解经济实验/实践的目的
Every practical task has a learning goal. Your teacher wants to see whether you can apply economic vocabulary to a real‑world situation. For example, if you are asked to run a class shop, you are not just selling pens – you are showing how price, quantity and customer behaviour are linked.
每项实践任务都有一个学习目标。老师希望看到你是否能将经济学术语运用到真实情境中。例如，如果让你经营一个班级商店，你不仅仅是在卖笔，而是在展示价格、销量和顾客行为之间的联系。
2. Planning and Designing Your Investigation | 规划和设计你的探究
Start by writing a clear question, such as 'How does changing the price of a snack affect the number sold?' Then list the steps you will take: how many price levels to test, who you will ask, and how you will record results. A simple plan prevents confusion during the activity.
先写下一个清晰的问题，比如'零食价格变化如何影响销售量？'然后列出你要采取的步骤：测试几个价格水平、询问哪些人、如何记录结果。一个简单的计划可以避免活动时的混乱。
3. Choosing Simple Data‑Collection Methods | 选择简单的数据收集方法
In Year 7, you will mainly use surveys, tally sheets or short observation logs. A tally chart is perfect for counting choices, like 'Which fruit is most popular?' Keep your method straightforward – you are learning the basics of gathering evidence, not designing a complicated experiment.
在七年级，你主要会使用调查问卷、计数表或简短的观察日志。计数表非常适合统计选择，比如'哪种水果最受欢迎？'保持方法简单直接——你正在学习收集证据的基础，而不是设计复杂的实验。
4. Using Basic Economic Models | 使用基础经济模型
You might create a simple demand schedule or a production possibility frontier (PPF) with paper and coloured dots. Models help you see patterns. If you are investigating trade‑offs, a PPF can show that producing more of one good means giving up some of another.
你可能会用纸和彩色圆点制作一个简单的需求表或生产可能性边界(PPF)。模型帮助你看到规律。如果你在探究权衡问题，PPF可以展示多生产一种商品意味着放弃部分另一种商品。
| Price per item (pence) | Quantity demanded (units) |
|---|---|
| 10 | 25 |
| 20 | 18 |
| 30 | 10 |
Example demand schedule: as price rises, quantity demanded falls – just as the law of demand predicts.
需求表示例：随着价格上升，需求量下降——正如需求定律预测的那样。
5. Working Effectively in a Team | 有效的团队合作
Many practicals are group tasks. Assign roles: one person tracks time, another writes down results, and a third acts as the 'buyer' or 'seller'. Listen to each other and stay focused on the task. Your teamwork is often assessed alongside the economic content.
许多实践任务都是小组活动。分配角色：一人计时，一人记录结果，另一人扮演'买方'或'卖方'。互相倾听，专注于任务。你的团队合作能力往往和经济学内容一起被评估。
6. Recording and Presenting Data Clearly | 清晰记录与展示数据
Use neat tables and simple graphs. A bar chart is great for comparing choices, while a line graph can show changes over time. Always label your axes and give your chart a title. Clear presentation makes your findings easier to understand and marks easier to earn.
使用整洁的表格和简单的图表。条形图很适合比较不同选项，折线图可以显示随时间的变化。始终给你的坐标轴加上标签，并给图表加上标题。清晰的展示能让你的发现更容易被理解，也更容易得分。
Quantity sold = 30 − (Price × 0.5)
销量 = 30 − (价格 × 0.5)
You might plot a simple relationship like the one above during your practical.
在实践活动中，你可能会画出像上面那样的简单关系图。
7. Analysing Your Results Using Economic Terms | 使用经济术语分析结果
Do not just describe what happened; try to explain why. Use phrases like 'because of scarcity', 'incentive', or 'opportunity cost'. For example, 'When price increased, fewer students bought the snack because they chose to save their pocket money instead – this is the opportunity cost of the snack.'
不要仅仅描述发生了什么；试着解释原因。使用诸如'因为稀缺'、'激励'或'机会成本'等短语。例如，'当价格上涨时，购买零食的学生减少了，因为他们选择把钱存起来——这就是零食的机会成本。'
8. Drawing Simple Conclusions | 得出简单的结论
A conclusion should answer your original question. Keep it short and directly linked to your data. If you found that demand drops when price goes up, say so clearly. Avoid adding ideas you did not test – conclusions are about what you actually observed.
结论应该回答你最初的问题。保持简短，并与你的数据直接挂钩。如果你发现价格上涨时需求下降，就清楚地说明。不要加入你没有测试过的想法——结论只涉及你实际观察到的内容。
9. Evaluating Your Practical Work | 评价你的实践活动
Think about what went well and what could be improved. Did you have enough time? Was your sample size too small? A good evaluation shows that you understand the limitations of your investigation. For instance, 'Only ten people were surveyed, so the results might not be true for the whole year group.'
想一想哪些地方做得好，哪些地方可以改进。你的时间够吗？样本量是否太小？一个好的评价表明你理解了探究的局限性。例如，'只调查了十个人，所以结果可能不适用于整个年级。'
10. Avoiding Common Mistakes | 避免常见错误
Watch out for these pitfalls: forgetting to label graphs, mixing up correlation and causation ('Ice cream sales went up when it was sunny, so the sun made people buy ice cream' is fine, but 'Ice cream sales caused the sun to shine' is not), and relying on opinions instead of data. Stick to the evidence you collected.
注意以下陷阱：忘记给图表加标签、混淆相关与因果('天热时冰淇淋销量上升，所以炎热让人们购买冰淇淋'是对的，但'冰淇淋销量导致太阳出来'就不对了)，以及依赖观点而非数据。要坚持使用你收集到的证据。
11. Using Feedback to Improve | 利用反馈来改进
After your teacher returns your work, read the comments carefully. If they suggested using more economic terms next time, make a note for your next practical. Learning from feedback is one of the fastest ways to improve your marks over the year.
老师发回作业后，仔细阅读评语。如果建议你下次使用更多的经济术语，就为下一次实践做个笔记。从反馈中学习是全年提高分数的最快方法之一。
12. Final Checklist Before Submission | 提交前的最终检查清单
Before you hand in your practical report, run through this checklist:
- Does my question match the task? / 我的问题与任务匹配吗？
- Is my data accurately recorded and displayed? / 我的数据记录和展示准确吗？
- Have I used at least three economic keywords? / 我是否至少使用了三个经济关键词？
- Does my conclusion answer the question? / 我的结论回答了问题吗？
- Have I checked for spelling and neatness? / 我是否检查了拼写和整洁度？
如果你能在每项上打勾，你就为取得好成绩做好了充分准备。
If you can tick every item, you are well prepared for a strong result.
