CHAPTER 1 OF 16 · Know both components and your starting point
1. Connect theory, performance and the development log
Back to contentsG3 Exercise and Sports Science asks you to explain movement, examine performance and evaluate how it can improve. Being active is helpful, but the subject also needs careful observation and reasoning. This guide covers K354. G3 identifies this subject's level rather than all your subjects.
The official 2027 SEAB ESS syllabus, checked on 14 October 2026, requires both components.
| Component | Assessment | Weight |
|---|---|---|
| Paper 1 Theory | 2-hour electronic examination; 80 marks; all questions compulsory | 40% |
| Paper 2 Coursework | 21 weeks; 80 marks; practical activities and development log | 60% |
Theory sections carry 20, 40 and 20 marks using texts, images and videos. Coursework includes one individual/dual activity and one team activity. Practical performance contributes 40% of the subject; the development log contributes 20%. Study physiology, motor learning, biomechanics, psychology and sociology together. Confirm your activities and supervised arrangements with your teacher.
CHAPTER 2 OF 16 · Know both components and your starting point
2. Diagnose knowledge, observation and application
Back to contentsChoose a recent answer or authorised performance observation and identify the weak step. Can you name a concept but not apply it? See an action but describe it vaguely? Propose practice without explaining the problem? Each gap needs a different task.
Try three small checks without notes: explain one movement, interpret a hypothetical performance table and identify a reason a decision might be ineffective. Compare with class material. Start with the gap that blocks the next step rather than assuming every area needs the same amount of revision.
Set a target such as "Describe the position and timing of the player before judging the decision." Use another authorised clip to retest. Recognising what happened in a familiar video is not the same as analysing an unfamiliar performance.
Keep the original answer and mark the missing link after correction. If your explanation improves because you identify a specific condition, practise finding that condition again. A precise repair is more useful than a general instruction to write more detail.
CHAPTER 3 OF 16 · Connect body systems, quantities and time scales
3. Learn body systems through movement relationships
Back to contentsFor a body-system topic, connect structure, function and the activity being discussed. Use labelled diagrams and authorised explanations. A list of anatomical names becomes more useful when you can explain how the relevant structures contribute to movement.
Use an original study prompt: identify the joint movement visible in a teacher-approved clip and connect it with the relevant structures. Describe the observed direction carefully before naming it. Do not assume a complex action involves only one joint or one muscle.
Study interacting systems as linked roles rather than isolated chapters. Ask what supplies the movement, what transports relevant materials and what coordinates the action in the context taught. The explanation should answer the particular question rather than list every system you know.
Draw a concept map from memory, then check it against class material. Correct a wrong connection as well as a missing label. Understanding depends on relationships; a diagram full of correct names can still contain an incorrect explanation of how they work together.
CHAPTER 4 OF 16 · Connect body systems, quantities and time scales
4. Use physiology calculations with units
Back to contentsIdentify the quantities and their relationship before substituting numbers. Explain what the result measures and the period it refers to. A calculator can perform arithmetic, but it cannot decide whether the chosen model answers the question.
In an original hypothetical exercise, heart rate is 80 beats per minute and stroke volume is 70 millilitres per beat. Their product is 5,600 millilitres per minute, or 5.6 litres per minute. This illustrates cardiac-output calculation; it is not a measurement or target for any particular student.
Check units so the unwanted quantity cancels appropriately. If the final unit is wrong, revisit the relationship or conversion. Do not compare values from different conditions as if they came from the same test.
Interpret cautiously. A single physiological value does not establish overall fitness, diagnose a condition or prescribe training. Use the information and assumptions in the learning task. Practical measurements and participation should follow your school's teacher-led procedures.
CHAPTER 5 OF 16 · Connect body systems, quantities and time scales
5. Distinguish immediate responses from adaptations
Back to contentsRead the time scale in the question. A change during one activity is different from a longer-term change following repeated training. Keep those categories separate in your notes and explain the relevant mechanism using authorised course material.
For an original reasoning task, compare an observation made during activity with a second observation after a period of supervised learning. Ask what other conditions would need to be controlled before attributing the difference to training. The timing alone does not prove the cause.
When discussing energy provision, avoid treating systems as switches where one operates and the others disappear. Use the course's account of relative contribution in the activity described. Explain how duration and intensity are relevant without replacing the specific context with a slogan.
Build comparison cards with condition, expected relationship and evidence. Retrieve the explanation before checking. If you only memorise the heading "long-term effect", you may struggle to apply it to a new question.
CHAPTER 6 OF 16 · Analyse movement, tactics and psychological context
6. Analyse skill learning through the task and environment
Back to contentsIdentify what the learner must perceive, decide and execute. A skill performed in changing conditions can demand different information from one performed in a more predictable setting. Explain the relevant difference rather than merely attaching a classification label.
Use an original classroom-analysis example: compare a pass to a stationary partner with a pass made while other players move. The second situation includes changing information. This comparison is for reasoning, not an unsupervised exercise prescription or an assessed activity requirement.
Ask how experience affects the task. A novice may need attention on a basic action while a more experienced performer can attend to additional cues. Avoid assuming that every learner progresses at the same rate or needs identical feedback.
For feedback, distinguish information about the result from information about the performance process where relevant. Then explain why the chosen information addresses the observed problem. "Give more feedback" is too vague unless you identify what should be communicated and how it helps.
CHAPTER 7 OF 16 · Analyse movement, tactics and psychological context
7. Describe biomechanics from visible evidence
Back to contentsBegin with the phase of movement and the observable position or action. Then apply the relevant principle. A technical term should explain what you see, not replace a description of the evidence.
For an original paper exercise, compare two hypothetical stances under the same stated conditions. Consider how base of support and centre-of-mass position could affect stability. Do not conclude that a wider stance is always best for every sporting task; movement demands and context matter.
Use diagrams with arrows to track force direction or movement. If a calculation is required, identify the model and assumptions. A simplified model can clarify a relationship while leaving practical factors outside its scope.
For projectile questions, consider the variables actually provided. Do not claim that one launch angle is universally optimal when height, speed, resistance or the task's objective differ. Explain the relationship in the stated model and acknowledge its limits where relevant.
CHAPTER 8 OF 16 · Analyse movement, tactics and psychological context
8. Break movement analysis into meaningful phases
Back to contentsChoose the action and define the phases using the model taught in class. Observe each phase separately, then reconnect them. A problem visible near the end may result from preparation earlier in the movement.
Use an original analysis task with an authorised video: identify preparation, action and completion where appropriate. Record what changes between phases. Then ask which observation is relevant to the question rather than describing every movement equally.
Separate observation from judgement. "The player turns after the ball has passed" describes timing. "The late turn reduces the opportunity to respond" is an interpretation that needs support from the context. Explain the link.
Do not prescribe a technical change from an incomplete observation alone. In practical learning, discuss it with your teacher and use approved methods. A study guide can teach how to reason about performance without replacing personalised coaching or safety assessment.
CHAPTER 9 OF 16 · Analyse movement, tactics and psychological context
9. Analyse tactics through options and consequences
Back to contentsAt a decision point, identify the performer's options and the information available. Consider positions, movement, rules and the objective of play. A successful outcome does not automatically prove the decision was the best one, just as an unsuccessful outcome does not establish that it was unreasonable.
For an original hypothetical team situation, a player can pass to a closely marked teammate or retain possession while another teammate moves into space. Explain the possible consequence of each choice using the stated information. Do not invent unseen players or claim that one option guarantees success.
Use notational records consistently in authorised practice analysis. Define what counts as an attempt, successful action or other event before counting. If definitions change between observations, comparisons become difficult to interpret.
Connect the finding with a question for supervised practice. If a decision is repeatedly late, examine the relevant cue or timing. The next task should address the identified mechanism rather than merely increase the number of repetitions.
CHAPTER 10 OF 16 · Analyse movement, tactics and psychological context
10. Use sports psychology without simplistic labels
Back to contentsStudy a psychological concept through its relationship with the specific performance. Motivation, attention and arousal can interact with the person and task. Avoid assuming that more excitement or more confidence always produces a better result.
Use an original classroom discussion prompt: two performers respond differently to the same competitive setting. Ask what task demands, experience and perceptions might help explain the difference. These are hypotheses to examine, not diagnoses of either person.
For goal setting, make a learning goal observable and relevant. "Explain one tactical choice using video evidence" is more actionable than "be better at sport." Practical performance goals and training decisions should be developed through the teacher-led process.
Separate a course explanation from personal mental-health advice. If a question supplies a performance scenario, analyse that scenario using authorised material. Do not claim that a generic strategy resolves every person's anxiety or difficulty.
CHAPTER 11 OF 16 · Use participation evidence, data and development reasoning
11. Evaluate sports participation and social context
Back to contentsFor a participation issue, identify the group, barrier or influence and its mechanism. Access, cost, expectations and facilities may affect people differently. A broad claim that everyone has the same opportunity needs evidence rather than assumption.
Use an original fictional case: a community activity has a low fee but inconvenient travel arrangements for some participants. Explain why price alone may not establish accessibility. Consider a response that addresses the transport barrier and any practical limits it creates.
For commercialisation, identify who gains resources and what incentives may change. Sponsors, organisers, performers and spectators can have different interests. Discuss the relevant benefits and concerns without treating commercial involvement as universally positive or negative.
For ethics, distinguish the action, rule and principle involved. Support a judgement with the supplied case and explain its effect on fairness or participation. Do not make allegations about real performers without verified evidence.
CHAPTER 12 OF 16 · Use participation evidence, data and development reasoning
12. Read performance data with a consistent basis
Back to contentsCheck the definition, units, conditions and number of observations before comparing results. A rate, total and percentage answer different questions. Use a common basis where the task requires it.
| Original hypothetical observation | Successful actions | Attempts |
|---|---|---|
| Session A | 12 | 20 |
| Session B | 15 | 30 |
Session A has a 60% success rate and B 50%. B has more successful actions but a lower proportion. The figures do not establish which session represents better overall performance without knowing the task and conditions. These are invented analysis values.
Explain the limitation of a comparison. Opponent difficulty, observation period or task conditions may differ. A higher number alone does not prove a training effect. Use the actual evidence and identify what additional information would support a stronger conclusion.
CHAPTER 13 OF 16 · Use participation evidence, data and development reasoning
13. Plan improvement through the teacher-led process
Back to contentsStart with the observed performance issue and evidence. Then identify a relevant factor to investigate. A plan should explain why its approach addresses that factor rather than offer a generic routine unrelated to the analysis.
For general study, practise planning on paper with hypothetical cases. State the goal, evidence needed and method for reviewing progress. This guide does not prescribe individual exercise intensity, duration or progression. Actual participation and training require your teacher's supervised arrangements.
Distinguish expected change from observed change. Before implementation, describe what you predict and how it could be checked. Afterwards, use genuine results and conditions. Do not rewrite the prediction as if every outcome had been anticipated.
Keep your development log your own. Describe what you actually analysed, planned, experienced and evaluated under the school requirements. Original examples in a guide should not be copied into assessed work as a personal record.
CHAPTER 14 OF 16 · Use participation evidence, data and development reasoning
14. Practise the electronic theory paper
Back to contentsUse the official practice environment and your school's instructions to become familiar with the task types. Practise reading text, images and video evidence carefully before answering. Do not assume a digital examination permits personal software or tools.
For a video question, locate the event relevant to the task and describe it precisely. Then explain its relationship with the concept asked. A general paragraph about the sport may miss the specific evidence in the clip.
Check selection and entry instructions for each item. A multiple-selection task differs from choosing one response. For a written explanation, make causal links clear and keep the answer tied to the stated conditions.
Build towards complete timed sets with a plan tested with your teacher. Review whether mistakes came from observation, theory, interpretation or interface handling. Repair the cause with a new task rather than only memorising the marked answer.
CHAPTER 15 OF 16 · Retest analysis and seek focused support
15. Keep a weekly knowledge-to-evidence cycle
Back to contentsMix retrieval, diagram explanation, video analysis, data interpretation and social-issue discussion. Align practical preparation with the school's programme. You can strengthen reasoning through short study sessions without independently adding physical training.
Keep a correction log with the issue, missing link and retest. After confusing totals and rates, calculate another hypothetical comparison. After vague movement analysis, describe another authorised clip using positions and timing. Delayed transfer shows whether the correction is secure.
Connect areas where evidence allows. A tactical decision may involve perception, movement and psychological context. Explain each link rather than naming several disciplines and assuming their interaction is obvious.
Measure progress by usable analysis: a precise observation, a valid calculation or a supported recommendation. Participation and knowledge both matter, but neither automatically establishes the other. The goal is to make performance reasoning clear and evidence-based.
CHAPTER 16 OF 16 · Retest analysis and seek focused support
16. Ask focused questions and use safe learning arrangements
Back to contentsBring your teacher the clip, data or explanation and one specific uncertainty. Ask which cue matters or whether the conclusion exceeds the evidence. Then apply the feedback to another authorised study task.
The immutable Secondary 1 Mathematics Tutor Clementi small-group tutorials page offers a foundation-building study-method reference: diagnose, repair in manageable steps and retest. It is not an ESS syllabus source and does not establish ESS tuition provision.
Use the official K354 syllabus and school instructions for assessment, practical activities and the development log. The situations and values here are original general learning exercises, not personal training prescriptions, actual performance records or SEAB questions.
Begin with one observation today. Describe what happened, apply a relevant concept and identify what evidence would test your explanation. This small cycle connects theory with performance while keeping the next learning step precise.
