IB History Internal Assessment: Source Investigation

The IB History Internal Assessment is your opportunity to act as a historian, moving beyond textbook narratives to conduct your own focused investigation. This independent research project, worth 25% of your Higher Level and 20% of your Standard Level grade, is not just a large essay; it is a structured demonstration of your skills in formulating questions, critically evaluating evidence, and constructing a coherent historical argument. Mastering the IA teaches you the discipline of historical thinking, a skill valuable far beyond the IB Diploma.

Formulating a Rigorous and Focused Research Question

The entire investigation hinges on the quality of your research question. A poorly conceived question leads to a vague, descriptive, or unmanageable project. Your question must be sharply focused, historically significant, and amenable to investigation using primary and secondary sources. It should be a "how" or "why" question that invites analysis and argument, not a "what" or "when" question that yields mere description.

Begin by identifying a broad topic of genuine interest, perhaps from your syllabus, such as "the causes of the Cuban Missile Crisis" or "the effectiveness of Gandhi's non-violent resistance." Then, narrow it down through preliminary reading. A weak question is: "What was the role of Martin Luther King Jr. in the Civil Rights Movement?" This is too broad and descriptive. A strong, focused alternative is: "To what extent was the strategic planning of the Southern Christian Leadership Conference (SCLC), under Martin Luther King Jr., the primary reason for the success of the Birmingham Campaign of 1963?" This question specifies a time, place, organization, and concept (strategic planning), and it uses the analytical frame "to what extent," which immediately sets up the need for evaluation and judgment against other possible factors.

Selecting and Critically Evaluating Sources

With a focused question, you can begin selecting sources. The IA requires analysis of both primary sources (materials from the period under study) and secondary sources (historians' interpretations). You must critically evaluate two key sources in depth within your investigation.

Selection is the first step of evaluation. Choose sources that are directly relevant to your question and that offer different perspectives or types of evidence. For a question on propaganda in Nazi Germany, you might select a filmed excerpt of a Hitler speech (primary visual/audio source) and a scholarly article analyzing the function of the Reichsministerium für Volksaufklärung und Propaganda (secondary source). Avoid sources that are too general or tangential.

Critical evaluation is demonstrated through a structured analysis often remembered by the acronym OPCVL (Origin, Purpose, Content, Value, Limitation). This is not a checklist but a framework for integrated discussion.

• Origin: Who created the source? When? Where? What is their background or position?
• Purpose: Why was this source created? For whom? What was the author's intended goal (to persuade, inform, record, celebrate, criticize)?
• Content: What does the source actually say or show? Summarize its key message or information.
• Value: Given the origin and purpose, how is this source valuable to your specific investigation? Does it offer a unique contemporary perspective? Reveal official policy? Provide statistical data? Its value is always tied to your research question.
• Limitation: Similarly, what are its limitations for your investigation? Consider bias, partial viewpoint, incomplete information, or the distance between its creation and the events described.

For example, a private letter from a soldier during the Vietnam War has high value as a firsthand account of experience and morale but is limited by being a single, subjective perspective. A government white paper has value as an official statement of policy but is limited by its purpose to justify actions to the public.

Structuring the Written Investigation

The IA has a strict 2,200-word limit and a mandated structure: the identification and evaluation of sources, an investigation, and a reflection. Each section has a distinct purpose.

Section 1: Identification and Evaluation of Sources (Approx. 500 words) This section is dedicated to your OPCVL analysis of two sources. Start by briefly stating your research question. Then, for each source, provide a full bibliographic citation and proceed to a synthesized critical evaluation. Do not write in bullet points or separate paragraphs for "Value" and "Limitation." Weave them together into a flowing analysis. A strong evaluation will explicitly connect the source's value and limitation back to the research question: "While this memoir provides invaluable insight into the decision-making process within the Politburo, its value is limited for understanding public sentiment, which is a key facet of my question regarding the stability of the regime."

Section 2: The Investigation (Approx. 1,300 words) This is the main body of your argument. It must be structured like a formal historical essay, with a clear introduction, several analytical body paragraphs, and a conclusion.

• Introduction: Clearly restate your research question, provide necessary historical context, and outline the argument (thesis) you will advance.
• Body Paragraphs: Each paragraph should be a point in your argument, not just a description of an event. Follow a "PEEL" structure: make a Point, provide Evidence from your sources (integrating brief, relevant quotations or data), Explain how the evidence supports your point, and Link back to your overall argument and research question. Synthesize evidence from both primary and secondary sources to support your analysis. Show you are engaging with historians' debates, not just reporting facts.
• Conclusion: Do not introduce new evidence. Summarize the argument you have made, directly answer the research question based on the investigation, and perhaps suggest broader implications or unresolved questions.

Section 3: Reflection (Approx. 400 words) This metacognitive section asks you to step back and consider the process of being a historian. Discuss the challenges you faced, the methods you used, and the ways your investigation highlighted the challenges of the historical discipline. You might reflect on: How did the limitations of your sources affect your conclusions? What, if anything, could a historian using different methods or sources learn about your topic? How has this process made you aware of the constructed nature of historical knowledge?

Demonstrating Historical Thinking and Meeting Assessment Criteria

Your work is assessed against four criteria, each aligned with a core historical skill.

Criterion A: Identification and Evaluation of Sources (6 marks) This assesses Section 1. To score highly, your source evaluation must be critical, focused, and synthesized. Explicitly connect the value and limitation of each source to your specific research question.

Criterion B: Investigation (15 marks) This assesses Section 2. High marks require a clear, analytical, and well-structured argument that is consistently focused on the question. Your analysis must be supported by relevant, well-integrated evidence from a range of sources. The investigation must show awareness of different perspectives and historical debates.

Criterion C: Reflection (4 marks) This assesses Section 3. A high-scoring reflection is critical and explicit about the methods and challenges of historical inquiry. It must move beyond a simple diary of your process ("I found it hard to find sources") to discuss the nature of historical knowledge itself.

Criterion D: Communication and Formal Presentation (5 marks) This assesses the whole work for clarity, structure, and academic integrity. Ensure your work is within the word limit, has a title page with your question and word count, uses consistent citations (footnotes or endnotes), and includes a full bibliography. Proofread meticulously.

Common Pitfalls

1. The Descriptive Summary: The most common error is summarizing sources or events instead of analyzing them. If a paragraph reads like a story ("This happened, then this happened"), you are not analyzing. Every piece of evidence must be used to support a point in your argument.
2. Source Evaluation as a Separate List: Writing the OPCVL as five disconnected sentences or bullet points in Section 1 will limit your score. The analysis must be a coherent, flowing paragraph that synthesizes these elements to judge the source's utility for your specific investigation.
3. Ignoring the Reflection's Purpose: Treating the reflection as a simple "what I learned" summary or a project diary misses the mark. You must engage with the methods and challenges of the historical discipline. Discuss how a historian's conclusions are shaped by the available evidence and their own choices.
4. Poor Source Integration: Dropping a quotation into a paragraph without introducing it or explaining its significance is ineffective. Use the quotation as evidence for a point you are making, and always follow it with your own analysis of what it means and how it supports your argument.

Summary

• The IA is a structured exercise in historical thinking, requiring you to formulate a research question, evaluate sources critically, and construct an analytical argument.
• Your research question must be narrowly focused, analytical ("how" or "why"), and researchable within the scope of the assignment.
• Source evaluation uses the OPCVL framework not as a checklist but as a guide for synthesizing an analysis of a source's value and limitations for your specific investigation.
• The written investigation has three distinct sections: a source evaluation, an analytical essay building an argument, and a reflection on the methods of historical inquiry.
• Success depends on aligning your work with the assessment criteria: demonstrating critical source evaluation (Criterion A), a focused and evidence-based investigation (Criterion B), insightful reflection on historical practice (Criterion C), and polished academic presentation (Criterion D).
