What this guide is for
QCE Modern History IA1 is a major Unit 3 assessment (25 percent). Strong performance requires source-analysis fluency, structured argument, and disciplined exam technique. This guide covers all three.

- Word count. 600-800 words.
- Stimulus. 3-5 historical sources (primary and secondary) on Unit 3 topic.

Five-part essay structure
Introduction (around 100 words).
Three sentences:
- Opening claim about the topic.
- Contention (direct answer to the prompt).
- Signpost: three lines of argument the body will develop.
Body paragraph 1 (around 150-200 words).
First line of argument. Engage at least one source. Apply OPCVR. Argue effect.
Body paragraph 2 (around 150-200 words).
Second line. Complicate or qualify the first. Engage with another source.
Body paragraph 3 (around 150-200 words).
Third line. Whole-text or structural-level argument. Engage with a third source.
Conclusion (around 60 words).
Reassert the thesis. Note historiographical contestability.
OPCVR source analysis
For each source you cite:
- Origin
- Who created? When? Where?
- Purpose
- Why was it created? For what audience?
- Context
- What was the broader historical situation?
- Value
- What can this source tell us about the topic?
- Reliability
- How trustworthy as evidence? What limits reliability?
Apply systematically. Strong responses do not just cite sources; they analyse them.
Source integration in body paragraphs
A reliable internal shape:
- Topic sentence linking to thesis.
- Reference to source by tag, with embedded short quotation.
- OPCVR analysis (especially value and reliability).
- Argue what the source shows about your line of argument.
- Closing sentence linking forward.
A worked body paragraph
For an IA1 on Australian conscription debates 1916-17:
The class divide that shaped opposition to conscription in 1916-17 is most clearly visible in the trade union and IWW responses. Source B, the cartoon from the Industrial Workers of the World (IWW) campaign (October 1916), depicts a wealthy businessman urging working-class Australians to fight while remaining safely at home; the cartoon's purpose is propagandistic but its value lies in revealing the class-based critique that drove much of the No vote. Source D, a historian's interpretation by Don Aitkin (1969), confirms that 'the No vote in 1916 was strongest in working-class districts of Sydney and Melbourne and weakest in the rural conservative seats.' Together the sources expose the class basis of opposition: a contemporary cartoon shows the rhetoric of resistance; a historian's secondary analysis confirms the demographic pattern.
A response of this kind, integrating two sources with explicit OPCVR awareness and argumentative purpose, secures top band.
