Introduction to Essay Writing in OCR History A

Welcome! Writing essays is the heart of your History A-Level. Whether you are exploring a specific 50-year period in British history or looking at a 100-year theme like "The Changing Nature of Warfare," the skills you need are very similar. The exam board, OCR, isn't just looking for a "story" of what happened. They want to see you build an argument and reach a substantiated judgement. This means making a claim and proving it with evidence. Think of yourself as a lawyer: you aren't just telling the jury what happened; you are trying to win an argument!

The Two Main Essay Types

In your H505 course, you will encounter two main types of essays across your three exam papers.

1. The Period Study Essay (Units 1 and 2)

These essays appear in Unit Group 1 (British) and Unit Group 2 (Non-British).
  • Weighting: Worth 20 marks.
  • The Goal: To analyse a specific "Key Topic" within the period you have studied.
  • The Focus: You will usually choose one essay from a choice of two (in Unit 1) or answer a specific essay question (in Unit 2).

2. The Thematic Essay (Unit 3)

These essays are the "big picture" questions in Paper 3.
  • Weighting: Two essays worth 25 marks each (50 marks total).
  • The Goal: To cover the whole period studied (at least 100 years).
  • The Focus: You must look at "turning points," "main developments," and how different themes relate to each other over a long stretch of time.
Note: For help with sources or interpretations, see our other chapters: "Source enquiry: evaluating four contemporary sources" or "Historical interpretations: comparing two extracts."

Mastering AO1: Your Secret Weapon

Almost all the marks for these essays come from AO1. This stands for "Assessment Objective 1." It sounds fancy, but it just means three things:
  1. Knowledge: Having the facts and dates ready.
  2. Organisation: Putting your ideas in a logical order.
  3. Analysis/Evaluation: Explaining why things happened and how important they were.
The Seven Key Concepts
OCR uses seven specific concepts to test your thinking. Try to use these words in your writing:
  • Cause: Why did it start?
  • Consequence: What happened because of it?
  • Change: What became different?
  • Continuity: What stayed the same?
  • Similarity: How was it like something else?
  • Difference: How was it unique?
  • Significance: How much did it actually matter?

How to Structure a Top-Level Essay

Don't worry if you find structuring difficult at first. Most students find that following a clear "recipe" helps them stay on track.

The Introduction

Keep it short and sweet. Define the key terms in the question and clearly state your judgement (your main argument). This tells the examiner exactly where you are going.

The Main Body Paragraphs (Thematic Approach)

Instead of writing chronologically (in time order), try to write thematically (by factor).
Tip: Use the PEEL method for every paragraph:
  • P - Point: Start with a clear topic sentence that links to the question.
  • E - Evidence: Provide specific historical facts (names, dates, events).
  • E - Explanation: Explain how that evidence proves your point.
  • L - Link: Bring it back to the question and your overall judgement.

The Conclusion

This is where you earn the highest marks. Don't just repeat what you’ve said. A "substantiated judgement" means you weigh up the factors. If the question asks "What was the main cause of X?", explain why your chosen cause was more important than the others you mentioned.

Special Advice for Thematic Essays (Unit 3)

Thematic essays cover a long time (100+ years). The biggest mistake students make is focusing too much on one "Depth Study" and ignoring the rest of the century.
  • Cover the Whole Period: Your answer must range across the entire date range given in the question (e.g., 1855–1964).
  • Identify Turning Points: OCR loves it when you can identify a moment where everything changed (a "turning point") and explain why it was more significant than other events.
  • Synthesis: This means looking at how different factors worked together across the whole century.

Common Pitfalls to Avoid

The "Information Dump": Avoid writing down everything you know about a topic. If it doesn't help answer the specific question, leave it out! Focus on analysis, not description.

The "Storyteller" Trap: Avoid writing "Then this happened, then that happened." This is narrative, not analysis. Always ask yourself: "Why am I telling the examiner this? How does it prove my argument?"

Ignoring the "Middle": In thematic essays, students often talk about the start of the century and the end, but forget the middle. Ensure your evidence is spread out across the 100 years.

Quick Review: Essay Success Checklist

  • Did I answer the specific question asked?
  • Did I use a range of the seven second-order concepts (Cause, Change, etc.)?
  • Is my judgement "substantiated" with evidence?
  • (For Unit 3) Did I cover the whole period of at least 100 years?
  • Is my essay analytical rather than just a story?
Key Takeaway: A great OCR History essay is a balanced argument. It uses specific facts to support a clear point of view, comparing different factors to decide which was the most significant. Practice your planning, and the writing will follow!
