📚 Year 13 WJEC Physical Education: Experimental/Practical Assessment Key Points | Year 13 WJEC 体育：实验/实践考核要点
The experimental and practical assessment components in Year 13 WJEC Physical Education are designed to evaluate a candidate's ability to apply theoretical knowledge in real-world sporting contexts. Success requires meticulous planning, accurate data collection, and the capacity to critically reflect on performance and experimental outcomes. This guide consolidates the key points you must master to excel in both the laboratory investigation and the practical performance analysis.
Year 13 WJEC 体育的实验与实践考核部分旨在评估考生在真实运动场景中应用理论知识的能力。成功需要周密的计划、精确的数据收集以及批判性反思表现与实验结果的能力。本指南汇集了你必须掌握的关键要点，助你在实验研究与实践表现分析中脱颖而出。
1. Understanding the WJEC Year 13 Practical Assessment Components | 理解 WJEC Year 13 实践考核组成部分
The practical assessment in Year 13 typically comprises three parts: a practical performance (as a performer or coach), an oral analysis (EAPI – Evaluating and Analysing Performance for Improvement), and an investigative study or experimental project. Understanding the weighting and marking criteria for each component is fundamental to effective preparation.
Year 13 实践考核通常包含三个部分：实践表现（作为表演者或教练）、口头分析（EAPI – 表现改进的评估与分析）以及一项研究调查或实验项目。理解每个部分的权重和评分标准是有效准备的基础。
In WJEC, the practical performance is externally moderated and must demonstrate advanced skills, tactical awareness, and the ability to apply strategies under pressure. The oral analysis requires you to analyse a live or recorded performance, identify strengths and weaknesses, and propose justified improvement strategies.
在 WJEC 中，实践表现由外部审核，必须展示出高级技能、战术意识以及在压力下运用策略的能力。口头分析要求你分析一场现场或录制的表现，识别优势与不足，并提出合理的改进策略。
The experimental component, often part of the investigative study, involves designing and conducting a physiological or biomechanical investigation. You will need to formulate a hypothesis, collect and process data, and draw conclusions linked to theoretical principles from the specification.
实验部分通常作为研究调查的一部分，涉及设计和开展一项生理学或生物力学研究。你需要提出假设、收集并处理数据，并得出与课程理论原理相联系的结论。
2. Designing a Valid Sport Science Experiment | 设计有效的运动科学实验
A well-designed experiment starts with a clear, testable hypothesis. For example, 'Caffeine supplementation significantly improves 30-metre sprint time compared to a placebo.' The independent variable (caffeine vs placebo), dependent variable (sprint time), and controlled variables (warm-up, footwear, rest intervals) must be clearly identified.
一个设计良好的实验从一个清晰、可检验的假设开始。例如，"与安慰剂相比，咖啡因补充显著改善30米冲刺时间"。必须清晰识别自变量（咖啡因 vs 安慰剂）、因变量（冲刺时间）和控制变量（热身、鞋具、休息间隔）。
Ensure your experimental design addresses reliability through repeated trials and validity by using recognised protocols such as the Wingate test or the Multi-Stage Fitness Test. Always pilot your procedure to refine timing and instructions.
通过重复试验确保实验设计的信度，并通过使用公认的协议（如 Wingate 测试或多阶段体能测试）来确保效度。始终进行预试验以完善计时和指导语。
Consider blinding and randomisation where possible to reduce bias. In a caffeine study, a double-blind, randomised cross-over design would strengthen the internal validity of your findings. Also identify potential confounding variables, such as participant sleep or dietary intake, and plan how to control or measure them.
在可能的情况下考虑盲法和随机化以减少偏差。在咖啡因研究中，双盲、随机交叉设计可增强研究结果的内部效度。同时识别潜在的混杂变量，如参与者的睡眠或饮食摄入，并计划如何控制或测量它们。
3. Conducting Physiological Tests with Precision | 精确开展生理测试
When measuring heart rate, blood lactate, or oxygen consumption, accurate use of equipment is critical. Ensure you calibrate gas analysers, check electrodes, and follow standardised procedures for skin preparation and sensor placement.
测量心率、血乳酸或摄氧量时，准确使用设备至关重要。确保校准气体分析仪、检查电极，并遵循皮肤准备和传感器放置的标准化程序。
For VO₂ max testing via treadmill, use a metabolic cart and perform a graded exercise test. Measure ventilation, O₂ and CO₂ concentrations to calculate oxygen uptake in ml·kg⁻¹·min⁻¹. Note the criteria for achieving a true VO₂ max plateau.
对于通过跑台进行的 VO₂ max 测试，使用代谢车并进行递增负荷运动试验。测量通气量、氧和二氧化碳浓度，以 ml·kg⁻¹·min⁻¹ 为单位计算摄氧量。注意达到真正 VO₂ max 平台的标准。
Always work with a partner for safety, and have emergency procedures in place. Document any deviations from the protocol as they must be discussed in your evaluation.
始终与伙伴合作以确保安全，并制定应急程序。记录任何偏离方案的情况，因为你必须在评估中讨论这些情况。
4. Practical Performance: Demonstrating Advanced Skills | 实践表现：展示高级技能
As a performer, you must evidence the ability to execute core and advanced skills under competitive conditions. Select a fully competitive situation where you can display decision-making, adaptation to opposition, and consistency.
作为表演者，你必须展现出在竞技条件下执行核心与高级技能的能力。选择一个完全竞争的环境，以展示决策能力、对对手的适应以及技术稳定性。
Provide a logbook or video evidence showing key moments of skill execution, tactical plays, and your role within the team structure. Emphasise your contribution to the game outcome, not isolated drills.
提供日志或视频证据，展示技能执行、战术打法以及你在团队结构中的角色的关键时刻。强调你对比赛结果的贡献，而非孤立的练习。
For individual sports, focus on technical models and biomechanical efficiency. For example, a swimmer should demonstrate effective streamlining, stroke rate control, and turning techniques under race conditions.
对于个人项目，注重技术模型和生物力学效率。例如，游泳运动员应展现在比赛条件下的有效流线型、划频控制和转身技术。
5. Coaching and Leadership: Evidence of Effective Communication | 教练与领导力：有效沟通证据
If assessed as a coach, you need to show session planning, clear instruction, and the ability to analyse and correct faults. Video evidence should capture your communication style, feedback timing, and progression management.
如果以教练身份接受评估，你需要展示课程规划、清晰的指导以及分析和纠正错误的能力。视频证据应捕捉你的沟通风格、反馈时机和进阶管理。
Link your session aims to specific performance weaknesses identified through observational analysis. Use formative assessment techniques, such as questioning and observation checklists, to evaluate learning.
将会话目标与通过观察分析识别的特定表现弱点联系起来。使用形成性评估技术，如提问和观察清单，来评价学习情况。
Demonstrate how you adapt coaching points for different learning styles – visual, auditory, and kinaesthetic – and provide evidence of athlete improvement over time.
展示你如何根据不同的学习风格（视觉、听觉和动觉）调整教练要点，并提供运动员随时间进步的证明。
6. The Oral Analysis (EAPI): Structure and Key Language | 口头分析（EAPI）：结构与关键语言
The EAPI (Evaluating and Analysing Performance for Improvement) oral exam requires a structured approach: introduction, analysis of strengths, analysis of weaknesses, and an action plan. Use technical terminology appropriate to your sport and the specification.
EAPI（表现改进的评估与分析）口试需要结构化的方法：引言、优势分析、劣势分析以及行动计划。使用适合你运动和课程大纲的专业术语。
When analysing a weakness, describe the cause, the
