AO2: Explanation and Analysis in WJEC GCSE History

What is AO2?

Assessment Objective 2 requires you to explain and analyse historical events and periods using second-order concepts such as causation, consequence, continuity, change, similarity, difference and significance.

In simple terms: why things happened, what resulted, and how important they were.

The Second-Order Concepts

These are the analytical tools historians use:

Why AO2 Questions Require More Than AO1

An AO1 answer gives facts. An AO2 answer explains why those facts matter.

AO1 only (insufficient): "Hitler became Chancellor in January 1933. Germany had high unemployment."

AO2 added: "Germany's 6 million unemployed by 1932 was the key reason Hitler became Chancellor in January 1933, because economic desperation made millions turn to radical solutions — the Nazis' promises of jobs and national renewal suddenly seemed credible. Without the Depression, the Nazi vote share would have remained at 2.6% (as in 1928), not the 37.4% achieved in July 1932."

The second version uses the fact (unemployment, 6 million) to explain the cause (credibility of Nazi promises) using the concept of causation.

How AO2 is Tested

"Explain why..." questions: AO2 is the primary objective. Structure:

1. State the reason (factor/cause)
2. Explain HOW it contributed to the event (the mechanism)
3. Use connecting language: "because", "therefore", "this meant that", "as a result"
4. Where possible, show how factors interconnected: "This combined with X to produce..."

Mark bands for "explain why" questions (12 marks):

• Level 1 (1–4): isolated points with no explanation; lists causes.
• Level 2 (5–8): some explanation; each cause linked to the outcome.
• Level 3 (9–12): explains multiple causes AND shows how they interconnected; prioritises or cross-references causes.

Writing an AO2 Paragraph: The PEC Method

• P — Point: Name the cause/reason/factor.
• E — Explain: How did this factor contribute to the event? Use "because", "therefore", "this meant."
• C — Contextualise: Add specific knowledge (dates, names, statistics) to develop the explanation.

Example (Why did the Weimar Republic fall?):

"One key reason the Weimar Republic collapsed was the economic catastrophe caused by the Great Depression [Point]. The Wall Street Crash (October 1929) triggered US banks to recall their loans to Germany, causing mass unemployment — over 6 million out of work by 1932 [Context]. This undermined confidence in the moderate centre parties, because voters blamed them for the crisis and turned to extremist alternatives that promised simple solutions [Explain]. This was crucial because it directly caused the Nazi vote to surge from 2.6% (1928) to 37.4% (July 1932) [Evidence + consequence]."

Prioritisation and Cross-Referencing (Level 3)

To reach the highest marks in AO2 questions, you must go beyond listing reasons and show how they relate to each other.

Prioritisation: Argue that one factor is more important than others and explain why:

"While long-term factors (weak Weimar constitution, Versailles humiliation) created the conditions for Hitler's rise, the Wall Street Crash was the decisive short-term trigger — without the Depression, the pre-existing weaknesses alone would not have brought Hitler to power by 1933."

Cross-referencing: Show how two causes worked together:

"The Depression (economic cause) combined with the weakness of coalition governments (political cause) to create a vacuum that Hitler could fill — neither factor alone would have been sufficient."
