All the Core IBDP History Techniques in One Reference Sheet

IB History rewards a precise, evidence-rich argument that engages with sources, named historians, and competing interpretations. This reference sheet gives you the OPVL framework for Paper 1, PEEL essay structure for Papers 2 and 3, and the analytical vocabulary, causation/consequence/significance models and IA structure you need to score in the top bands at SL and HL.

📜

Paper 1 source-based questions: Q1 comprehension, Q2 OPVL, Q3 compare/contrast, Q4 mini-essay

✍️

Paper 2 world history essay structure with PEEL paragraphs and named historians

🌍

Paper 3 (HL only) regional in-depth study — four-region overview and essay technique

🧠

Historiography vocabulary, causation/consequence frameworks and Historical Investigation IA

Paper 1 — Source-Based Questions (Prescribed Subjects, SL & HL)

1 hour, 4 questions on a single prescribed subject — answer ALL four in order. Same paper for SL and HL.

Q1 (a) & (b) — Comprehension / Identification (5 marks)

Short-answer extraction from one or two sources.

Technique

Paraphrase the source in your own words — do NOT copy verbatim. Cite the source explicitly ('Source A states that...').

Q1(a) — 3 marks

Make 3 distinct supported points from the source — one mark each.

Q1(b) — 2 marks

Identify the message/meaning of a visual source (cartoon, photo) — focus on symbolism and the creator's point.

Spend ~7 minutes on Q1 total — quick, accurate, no analysis needed.

Q2 — OPVL Source Evaluation (4 marks)

Evaluate the value AND the limitations of a source with reference to its origin and purpose.

O — Origin

Who created it? When? Where? What kind of source (speech, memoir, government report, photograph)?

P — Purpose

Why was it created and for whom? To inform, persuade, justify, record, propagandise?

V — Values

What insight does the origin/purpose give a historian investigating the prescribed subject?

L — Limitations

What bias, gap, or limitation does the origin/purpose create? Be source-specific — avoid generic 'it is biased'.

Two values + two limitations, each tied explicitly to origin or purpose, secures full marks.

Q3 — Compare and Contrast (6 marks)

Identify similarities AND differences between two sources.

Structure

One paragraph of comparisons (similarities) + one paragraph of contrasts (differences) — running comparison, not source-by-source summary.

Linking phrases

'Both sources argue that...', 'Whereas Source A claims..., Source B suggests...', 'In contrast to Source A, Source B...'

Aim

3 developed comparisons + 3 developed contrasts, each grounded in direct evidence from BOTH sources.

Q4 — Mini-Essay Using All Four Sources + Own Knowledge (9 marks)

Evaluate a claim using all four sources AND your own contextual knowledge.

Structure

Brief intro stating position → 2–3 body paragraphs each integrating sources + own knowledge → short conclusion with overall judgement.

Source integration

Reference every source by letter (Source A, B, C, D). Don't quote at length — paraphrase and analyse.

Own knowledge

Specific dates, names, events that extend or qualify the sources — not generic background.

Spend ~30 minutes on Q4. This question carries the most marks — plan it.

Paper 2 — World History Topics Essay (SL & HL)

1.5 hours, 2 essays from 2 different world history topics. Choose 2 of 12 topics; same paper SL/HL.

The 12 World History Topics — Common Choices

Topics 10–12 are the most popular IB choices.

Topic 10

Authoritarian states (20th century) — rise, consolidation, policies of leaders such as Hitler, Stalin, Mao, Castro.

Topic 11

Causes and effects of 20th-century wars — WWI, WWII, Cold War conflicts (Korea, Vietnam), regional wars.

Topic 12

The Cold War: superpower tensions and rivalries (20th century).

Essay Structure — Thesis-Driven

Markschemes reward a sustained, analytical argument from the first sentence.

Introduction

Define key terms in the question → state your thesis (overall judgement) → signpost 3–4 lines of argument.

Body — 4–5 PEEL paragraphs

Point (argument) → Evidence (specific dates, names, statistics) → Explanation (analyse why this evidence supports the point) → Link (back to question and thesis).

Counterargument

At least one paragraph engaging the opposing view — then explain why your thesis still holds (AO3 evaluation).

Conclusion

Reasoned overall judgement weighing the arguments — no new evidence, no list-summary.

Aim for 1,000–1,400 words per essay. Quality of argument > number of facts.

Engaging With Historians (AO5)

Named historians distinguish a top-band IB essay.

Use 2–3 named historians per essay where the topic permits — e.g. 'Ian Kershaw argues...', 'Whereas Richard Evans contends...'.

Explain WHY they differ

Different evidence used | different methodology | different time of writing | different ideological position (Marxist, structuralist, intentionalist, revisionist).

Don't drop in historian names without engagement — evaluate which interpretation is more convincing and why.

Paper 3 — Regional In-Depth Study (HL ONLY)

2.5 hours, 3 essays from 1 chosen region. HL students only — deeper, more specific case-study evidence than Paper 2.

The Four HL Regions — Choose ONE

Schools select one of four regional options for the entire HL cohort.

Africa & the Middle East

E.g. Developments in Africa post-1800; Arab–Israeli conflict; post-colonial state-building.

The Americas

E.g. Civil Rights movement; Cold War in the Americas; political developments in Latin America.

Asia & Oceania

E.g. Developments in China (1860–1976); Japan post-Meiji; decolonisation in South/SE Asia.

Europe

E.g. Imperial Russia/USSR; inter-war Europe; post-war Europe and the Cold War.

Paper 3 Essay Technique — Same PEEL Frame, Deeper Evidence

The structure mirrors Paper 2, but examiners expect more specific names, dates and statistics.

Depth marker

Two or three precise pieces of evidence per paragraph rather than one — e.g. specific battles, named ministers, exact dates of legislation.

Counterargument

Engage with at least two competing interpretations (often named historians) per essay.

Timing

~50 minutes per essay (3 essays in 150 minutes). Plan each for 5 minutes before writing.

Historiography Vocabulary & Argument Connectives

Precise academic phrasing signals top-band historical thinking at SL and HL.

Introducing Arguments

A compelling case can be made that... | The most persuasive explanation is... | Central to any interpretation of X is... | A crucial factor in understanding Y was...

Developing & Supporting Points

This is corroborated by... | The evidence clearly demonstrates... | This is particularly significant because... | This is further evidenced by...

Counterargument & Qualification

It could be argued, however, that... | This interpretation must be qualified by... | While X had some validity, it nevertheless... | The weight of evidence suggests that...

Concluding & Weighing

On balance... | Ultimately, the most persuasive case is... | Taking all factors into account... | The evidence overwhelmingly suggests...

Causation, Consequence & Historical Significance

Show you can distinguish between types of historical explanation — required across all three papers.

Causation Analysis

Why did this happen? Distinguish long-term, short-term and trigger causes.

Long-term causes

Underlying structural conditions — economic, social, ideological — that built over years or decades.

Short-term causes

Precipitating events in the months or weeks before the outcome.

Trigger

The specific spark that converted tension into action.

Linking

Show how they interact: 'X created the conditions in which Y became possible because...'

Consequence Analysis

What were the effects? Distinguish timeframes and intentions.

Immediate (weeks/months) → medium-term (years) → long-term (decades) → intended vs unintended consequences.

Historical Significance — The 5Rs Framework

Judge how important a person, event, or development was.

Remembered

How prominently is it remembered today and in the period?

Resonant

Does it speak to issues beyond its own time?

Resulted in change

Did it cause measurable change in lives, institutions, or ideas?

Revealing

What does it reveal about the wider period or society?

Remarkable

Was it striking or unusual at the time and since?

Always EXPLAIN why something is significant — don't just assert significance.

Engaging Named Historians — Why They Differ

Top-band essays explain interpretive disagreement, not just list it.

Different evidence

Newly available archives, oral histories, or quantitative data.

Different methodology

Social vs political vs cultural vs economic history; quantitative vs qualitative.

Different time of writing

Cold-War-era vs post-1991 vs 21st-century perspective.

Different ideological position

Marxist, structuralist, intentionalist, revisionist, post-colonial, feminist.

Internal Assessment — The Historical Investigation

2,200-word individual research investigation, externally moderated. 25% of SL final mark, 20% at HL.

Section A — Identification & Evaluation of Sources (~500 words, 6 marks)

Choose two sources of clear value for your investigation and evaluate them with OPVL.

Open with

A clear research question phrased as a focused, debatable historical question.

For each source

Reference (author, title, date, type) → explain its relevance → analyse value AND limitations using OPVL.

Section B — Investigation (~1,300 words, 15 marks)

The actual historical investigation — analytical, evidence-rich, with named historians.

Treat it like a Paper 2 essay: thesis-driven introduction → PEEL body paragraphs → counterargument with named historians → reasoned conclusion.

Footnote every fact and quotation. Use a recognised citation style (Chicago/Harvard) consistently.

Section C — Reflection on Historical Methods (~400 words, 4 marks)

Reflect on what the investigation revealed about how historians work.

Address

Methods used and their limits | challenges of source selection | role of bias/perspective | how historians construct knowledge under uncertainty.

This is reflection, NOT a summary of conclusions. Connect to specific challenges YOU encountered.
