Introduction to Evaluation and Synthesis

Welcome! If you are preparing for your IB History Paper 1, you have reached the "Main Event." Whether you are sitting your exams in 2027 or 2028, the final question of the source paper is where you pull everything together. This chapter focuses on how to combine the sources provided in the exam with your own knowledge (the facts you learned in class) to create a powerful, balanced argument.

Think of this like being a lawyer in a courtroom. The sources are the "exhibits" (the physical evidence), and your own knowledge is the "legal context" (the background information). You need both to win the case!

The Two Exam Formats

Depending on when you take your exam, the structure of this task looks slightly different, but the skill remains the same.

For the 2027 Sessions (Current Syllabus)

The final question (Question 4) is worth 9 marks. It is an evaluative question that asks you to reach a conclusion using both the sources and your own knowledge. This single question accounts for nearly 40% of the marks for Paper 1!

For the 2028 Sessions (New Syllabus)

The focus shifts toward synthesis and perspectives. You will be asked to synthesize different perspectives across the sources while applying knowledge from your Focused Study (such as Conflict and Displacement or Protest and Change) throughout your response.

Quick Note: To learn how to analyze just one source's value or how to compare two sources, see the previous chapters in this section.

What is "Own Knowledge" (OK)?

Own Knowledge refers to specific historical facts, dates, names, and events that are not mentioned in the sources provided. For example, if you are answering a question on Rights and Protest and the sources don't mention the 1963 March on Washington, but you do, that is Own Knowledge.

Why it matters: If you only use the sources, you cannot get into the highest mark bands. If you only use your own knowledge and ignore the sources, you are writing a general essay, not a source-based response. You need a balance.

Did you know? In the 2027 exam, examiners usually look for a roughly 50/50 split between source evidence and own knowledge. In 2028, your knowledge must be applied "throughout" the response.

Step-by-Step: Building Your Argument

Step 1: Analyze the Prompt

Most of these questions start with "To what extent..." or "Evaluate the claim that...". Identify the main argument you need to test.
Example: "To what extent was the Civil Rights Movement successful in achieving its aims between 1954 and 1965?"

Step 2: Sorting Your Evidence

Before writing, quickly group your evidence. Which sources say "Yes, it was successful"? Which sources say "No, it wasn't"? Then, jot down two or three pieces of Own Knowledge that support each side.

Step 3: The "Integrated" Approach (Weaving)

The best students don't write about all the sources first and then all their knowledge at the end. Instead, they weave them together.
Analogy: Think of it like making a marble cake. You don't want a layer of chocolate and then a layer of vanilla; you want them swirled together in every bite!

A "weaved" paragraph looks like this:
"Source C suggests that the Montgomery Bus Boycott was a success because it led to the desegregation of buses (Source Evidence). This is supported by the fact that in 1956, the Supreme Court ruled in Browder v. Gayle that bus segregation was unconstitutional (Own Knowledge). However, Source D argues that progress was slow, a view supported by the fact that many Southern states used 'massive resistance' to delay integration for years (Own Knowledge)."

Key Skills for Success

1. Synthesis (The 2028 Goal)

Synthesis means looking at how sources talk to each other. Do they agree? Do they offer different perspectives on the same event? In the 2028 syllabus, you are specifically looking for perspectives—how different people at the time (or different historians) viewed the situation.

2. Evaluation

To evaluate means to weigh up the evidence. Don't just list facts. Tell the examiner which evidence is stronger. For example, is a primary source from a protest leader more "valuable" for understanding motives than a government report?

3. Using All Sources

In the 2027 exam, you are expected to use all four sources in your final answer. If you skip one, you are leaving marks on the table!

Key Takeaway: The goal is to show that you can use the evidence in front of you (Sources) while proving you understand the bigger historical picture (Own Knowledge).

Common Mistakes to Avoid

The "Source Dump": Listing what Source A says, then Source B, then Source C, without ever connecting them to a main argument.

The "Ghost Knowledge": Mentioning a fact but not explaining how it relates to the source or the question.

Ignoring the Dates: Check the dates in the prompt! If the question asks about 1931–1941 (Japanese expansion), don't spend half your essay talking about 1945.

Vague Language: Avoid saying "The source is good." Instead, say "Source A provides a valuable perspective on the motives of..."

Quick Review Box

1. Question Type: Evaluation/Synthesis (The final, big-mark question).
2. Ingredients: Use ALL sources + specific Own Knowledge (names, dates, events).
3. The "Golden Rule": Weave your knowledge and source evidence together in the same paragraph.
4. Command Terms: Look for "To what extent" (requires a balanced "yes/no" argument) or "Evaluate" (requires weighing strengths and weaknesses).

Summary Checklist

• Did I answer the specific question asked?
• Did I use every source provided?
• Did I include specific facts (Own Knowledge) that aren't in the sources?
• Did I present more than one perspective or side of the argument?
• Did I reach a clear conclusion that "weighs up" the evidence?
