Quick Answer

'Define' means give the precise meaning. 'Outline' means give a brief account or summary. 'Describe' means give a detailed account. These are lower-level command terms but still require precision - vague or incomplete answers lose marks.

What You'll Learn

  • Define = precise meaning (often one sentence)
  • Outline = brief summary of key points
  • Describe = detailed account of features or process
  • Match your answer length to the marks available

What 'Define' Requires

Definitions should be precise, accurate, and concise. Use technical terminology correctly. In most cases, a good definition is 1-2 sentences. Learn key definitions for your subject - they're often worth 1-2 marks and are quick wins in exams.

Pro Tip

Memorise key definitions from your syllabus. These are often directly from the IB subject guide and must be accurate.

What 'Outline' Requires

An outline gives the main features without detailed explanation. Think of it as a summary or overview. Hit the key points without going into depth. Outline questions are often worth 2-4 marks.

  • Identify the main points or features
  • Present them briefly and clearly
  • Don't go into detailed explanation
  • Ensure you cover all key aspects

What 'Describe' Requires

Description gives a detailed account of characteristics, features, or processes. Unlike outline, description requires fuller explanation of each point. Describe questions are worth more marks and require more development.

  • Give a full account with relevant detail
  • Cover all significant features or steps
  • Use specific examples or data if relevant
  • Organise your description logically
