How to Answer IB SEHS Questions Effectively
Success in IB Sports, Exercise and Health Science (SEHS) depends less on memorising content and more on responding precisely to what the question is asking. Many students lose marks not because they lack knowledge, but because their answers do not match the command term used in the question.
Understanding how command terms work—and shaping your response accordingly—is one of the most reliable ways to improve essay and short-answer performance.
1. Understand What IB Command Terms Actually Demand
IB command terms are instructional. They tell you how to use your knowledge, not just what to include. Treating all questions the same way leads to over-analysis in some responses and shallow answers in others.
Before writing anything, identify the command term and mentally translate it into an action.
For example:
- Are you being asked to present information, or to judge effectiveness?
- Do you need mechanisms and reasoning, or balanced comparison?
Your entire response should be shaped by that decision.
2. Match Your Depth of Response to the Command Term
Different command terms require different levels of thinking and structure.
Describe
This requires factual detail only. You should outline characteristics or processes without explaining why they occur.
Example expectation:
Clear statements of physiological changes, such as increases or decreases in heart rate or stroke volume, without causal reasoning.
Explain or Analyze
Here, you must show cause-and-effect relationships. Examiners expect mechanisms, pathways, or theories.
Example expectation:Link dehydration to reduced plasma volume, lowered stroke volume, increased heart rate, and impaired thermoregulation.
