📚 Year 7 WJEC PE: Case Study Practical Exercises | WJEC 7年级体育：案例分析实战演练
Welcome to your practical case study workout! In Year 7 WJEC Physical Education, you are not just learning how to move – you are learning how to think about movement. A case study in PE means you watch, analyse and evaluate a real or recorded sports performance, then use your knowledge to explain what is happening and how it can be improved. This article will guide you through a series of hands-on case study challenges, giving you the skills to observe like a coach and talk about sport with confidence.
欢迎来到你的案例分析实战训练！在 WJEC 七年级体育课中，你不仅要学习如何运动，更要学习如何思考运动。体育案例研究意味着你要观察、分析和评估一个真实的或录制的运动表现，然后用你的知识解释发生了什么以及如何改进。这篇文章将带你通过一系列动手操作的案例研究挑战，让你像教练一样观察，并自信地谈论运动。
1. What Is a Case Study in PE? | 什么是体育案例研究？
A case study in PE is like being a detective. You gather information about a performer or a team, spot strengths and weaknesses, and suggest ways to get better. It can be based on a video clip, a live demonstration, or even your own performance.
体育中的案例研究就像当一名侦探。你收集关于一名运动员或团队的信息，找出强项和弱项，并提出改进的方法。它可以基于一段视频、现场示范，甚至是你自己的表现。
You will often use a structured approach: observe, describe, analyse, and evaluate. This helps you break down complex movements into simple parts and understand the ‘why’ behind every action.
你通常会用到一套结构化的方法：观察、描述、分析、评估。这能帮你把复杂的动作分解成简单的部分，并理解每个动作背后的“为什么”。
2. The Importance of Observation | 观察的重要性
Good analysis starts with careful observation. Before you can judge a skill, you must really watch it. Focus on body shape, timing, speed, and whether the movement looks smooth or jerky.
好的分析从仔细观察开始。在评价一项技能之前，你必须真正看清楚。关注身体形状、时机、速度，以及动作看起来是流畅还是僵硬。
Try this: watch a short clip of a basketball free throw. Note the bend of the knees, the follow-through of the wrist, and the flight of the ball. These details become your evidence.
尝试这个：观看一段篮球罚球的短视频。注意膝盖的弯曲、手腕的跟随动作以及球的飞行轨迹。这些细节就是你的证据。
3. Analysing Movement Skills | 分析运动技能
When you analyse a movement, break it into three phases: preparation, execution, and recovery. For example, in a tennis forehand, preparation includes the backswing, execution is the forward swing and contact, and recovery is the return to a ready position.
当分析一个动作时，把它分成三个阶段：准备、执行和恢复。例如，在网球正手击球中，准备阶段包括向后引拍，执行阶段是向前挥拍和触球，恢复阶段是回到准备姿势。
Use key words like ‘balanced’, ‘coordination’, ‘timing’, and ‘control’ to describe what you see. These terms show you are thinking like a PE student.
用“平衡”、“协调”、“时机”和“控制”等关键词来描述你所看到的。这些术语表明你正在像体育生一样思考。
4. Case Study: Sprint Start Technique | 案例研究：短跑起跑技术
Let’s apply your skills to a sprint start. Watch a runner explode from the blocks. You might notice their head stays low initially, arms pump vigorously, and they drive forward with powerful leg action.
现在把你的技能运用到短跑起跑上。观察一名运动员从起跑器上爆发式冲出。你可能会注意到他们的头部起初保持低位，双臂有力地摆动，双腿强劲地蹬地推动身体前进。
Now analyse: what could go wrong? If the runner lifts their head too early, they lose a straight line of force. If their first strides are too long, they over-balance. These cause slower acceleration.
现在分析：哪里可能出错？如果运动员过早抬头，就会失去力的直线传递。如果第一步跨得太大，会导致过度失衡。这些都会降低加速效率。
Create a checklist: 1) Head in line with spine, 2) Explosive first push, 3) Arms driving at 90 degrees, 4) Strides quick and short at first. Your case study becomes a coaching tool.
创建一个检查表：1) 头与脊柱成一线，2) 首次蹬地爆发力强，3) 双臂以90度角摆动，4) 初始步幅短而快。你的案例研究就变成了教练工具。
5. Tactical Analysis in Invasion Games | 入侵性游戏中的战术分析
Invasion games like netball, football, and basketball require smart decision-making. A case study here focuses on tactics: where to move, when to pass, and how to create space.
无挡板篮球、足球和篮球等入侵性游戏需要聪明的决策。这里的案例研究关注战术：移动到哪里、何时传球以及如何创造空间。
For example, in football, watch a midfielder receiving a pass under pressure. Do they scan before receiving? Do they open their body to play forward? These decisions shape the attack.
例如，在足球中，观察一名中场球员在压力下接球。他们在接球前是否观察了周围？他们是否打开身体以便向前传球？这些决策决定了进攻的质量。
When building your case study, ask: What options did the player have? Which did they choose and why? What was the outcome? This thinking moves you from “good pass” to a deeper understanding.
在构建你的案例研究时，问自己：这名球员有哪些选择？他们选择了哪个？为什么？结果如何？这种思考让你从“传得好”过渡到更深层的理解。
6. Case Study: Passing Decision in Netball | 案例研究：无挡板篮球中的传球决策
Netball is a perfect sport for a case study because of the limited movement with the ball. Watch a centre player who receives the ball in the middle third. They can pass to the goal attack, wing attack, or backwards.
无挡板篮球因其持球移动限制，是案例研究的完美运动。观察在中场区接球的中锋队员。他们可以传给球门主攻手、边锋或向后传。
Analyse their choice: if the goal attack is closely marked, a long pass is risky. A short pass to the wing attack retains possession. But is the wing attack in a better position to feed the circle? Every pass has a consequence.
分析他们的选择：如果球门主攻手被严密盯防，长传有风险。短传给边锋可以保持控球权。但边锋是否处在更好的位置来喂球给得分区？每一次传球都有后果。
Your case study evaluation: the player chose the correct short pass and the team advanced safely. However, they missed an opportunity to switch play quickly. A recommended improvement: scan before receiving to know where free players are.
你的案例研究评估：该球员选择了正确的短传，球队安全推进。但他们错过了一次快速转移进攻方向的机会。建议改进：在接球前观察，预知哪里有空位队友。
7. Fitness Components Case Study | 体能要素案例研究
A great case study links performance to fitness. If a netball player is struggling to get free in the fourth quarter, what fitness components are lacking? Possibly cardiovascular endurance and agility.
优秀的案例研究将表现与体能联系起来。如果一名无挡板篮球运动员在第四节难以摆脱防守，缺少哪些体能要素？可能是心血管耐力和敏捷性。
Table of common fitness components and their signs in a performance:
| Fitness Component | 表现迹象 (Sign in Performance) | 案例示例 (Case Example) |
|---|---|---|
| Cardiovascular Endurance (心血管耐力) | Player slows down, hands on knees | Football midfielder late in the game |
| Agility (敏捷性) | Can’t change direction quickly, falls behind | Basketball defender beaten off the dribble |
| Speed (速度) | Loses sprint to a loose ball | Rugby winger chasing a kick |
| Strength (力量) | Easily pushed off the ball | Netball goal shooter holding position |
When writing your case study, connect the physical weakness to the technical failure. This shows depth in your analysis.
在撰写案例研究时，将体能弱点与技术失误联系起来。这体现了你分析的深度。
8. Health and Well-being Scenario | 健康与幸福情景
WJEC PE also covers broader well-being. A case study could focus on a teenager who feels tired before training. Analyse lifestyle factors: sleep, nutrition, hydration and stress.
WJEC 体育也涵盖更广泛的幸福感。案例研究可以聚焦于一个训练前感到疲倦的青少年。分析生活方式因素：睡眠、营养、水分和压力。
You notice the performer had only 6 hours of sleep and skipped breakfast. This leads to low energy and poor concentration. In your evaluation, suggest a sleep routine and a pre-training snack like a banana.
你注意到该运动员只睡了6小时且没吃早饭。这导致能量不足和注意力不集中。在你的评估中，建议制定睡眠规律和训练前吃一根香蕉等零食。
This type of case study links science to everyday choices, making you a more thoughtful performer yourself.
这类案例研究将科学与日常选择相结合，使你成为一个更具思考能力的运动者。
9. Self-Reflection and Peer Feedback | 自我反思与同伴反馈
You are not just an observer – you are also a performer. Creating a case study on your own performance through video replay is powerful. Watch yourself do a balance skill, like a headstand or a yoga pose.
你不只是观察者——你也是执行者。通过视频回放对自己的表现进行案例研究是非常有效的。观看自己做一项平衡技能，如倒立或瑜伽姿势。
Note what feels right and what looks right – they are not always the same! Then trade feedback with a partner using your observation checklist. Remember to be kind, specific and helpful.
注意感觉对的与看起来对的——它们并不总是一致！然后用观察检查表与同伴交换反馈。记住要友善、具体且有帮助。
10. Creating Your Own Case Study | 设计你自己的案例研究
Now it’s your turn. Choose a sport you enjoy. Film a short skill (e.g., a volleyball serve) or watch a 30-second clip online. Follow this simple format:
现在轮到你了。选择一项你喜欢的运动。拍摄一个简短技能（如排球发球）或在线观看一段30秒的视频。遵循以下简单格式：
1. Describe: What do you see? (body position, movement pattern)
2. Analyse: Why is it happening? (timing, force, technique)
3. Evaluate: How good is it? What could improve?
4. Recommend: Give one coaching point or drill.
1. 描述：你看到了什么？（身体姿势、动作模式）
2. 分析：为什么会这样？（时机、力量、技术）
3. 评估：表现如何？如何改进？
4. 建议：给出一个指导要点或练习。
Share your case study with the class. You’ll quickly see how different observers notice different details – that’s the beauty of PE analysis.
与全班分享你的案例研究。你很快就会看到不同的观察者会注意到不同的细节——这就是体育分析的魅力所在。
11. Common Mistakes and How to Avoid Them | 常见错误及避免方法
Beginners often make these errors in case studies: focusing only on the outcome (“he missed”), using vague words (“she was bad”), or forgetting to link cause and effect. Avoid these by always asking ‘why’ three times.
初学者在案例研究中常犯这些错误：只关注结果（“他投丢了”），用词模糊（“她做得不好”），或忘记联系因果关系。通过总是追问三次“为什么”来避免这些。
Another trap is describing a skill without evidence. Always back up your point: “The leg drive was weak because the knee only bent to 120 degrees instead of 90 degrees.” Numbers and comparisons make your case study powerful.
另一个陷阱是描述技能但没有证据。一定要支撑你的观点：“蹬腿无力，因为膝盖只弯曲到120度而不是90度。”数字和比较让你的案例研究更有力。
12. Conclusion and Further Practice | 总结与进阶练习
Case studies turn you from a player into a thinker. You are now equipped to watch sport with a sharper eye, give useful feedback, and improve your own performance. Keep a mini case study notebook for training sessions or matches you watch.
案例研究让你从一名运动员转变为思考者。你现在已经具备以更敏锐的眼光观看运动、提供有用的反馈并改进自己表现的能力。为你观看的训练课或比赛准备一本迷你案例研究笔记本。
Challenge yourself: next time you watch a live match, pick one player and write a mental case study on them. Notice their movement off the ball, their communication, and their decision-making. PE is all around you – keep analysing!
挑战自己：下次观看现场比赛时，挑选一名球员，在心里为他们写一份案例研究。注意他们无球跑动、沟通和决策。体育无处不在——继续分析吧！
