What you'll learn
- Distinguish a source from a claim made about it.
- Compare what different records can establish.
- Build a cautious explanation using corroboration.
Begin with a question
A photograph, map, letter or account does not answer every possible question. Decide what you want to investigate before selecting a source. A record may be useful for one question while leaving another unanswered. Ask learners to identify which part of a source supports a claim, instead of treating a source as a container of facts to copy.
Use a fictional photograph of a market and ask what it shows about the arrangement of stalls. The visible arrangement can support that enquiry. The image alone cannot establish the price of every product or the experience of everyone who visited the market.
Consider origin and purpose
Knowing who made a record, when it was made and why it was produced can help interpret it. A contemporary record is not automatically complete or neutral, and a later account is not automatically useless. Relate the source’s strengths and limitations to the question. Avoid assuming that one perspective represents every group.
A fictional poster advertises a new bus route, while a passenger recalls travelling on it years later. The poster can show how the route was promoted; the memory can offer an experience of using it. Neither alone establishes how every passenger experienced the service.
Corroborate without counting agreement mechanically
Compare sources that offer different kinds of evidence or perspectives. Agreement is more informative when records are independent than when several simply repeat one original claim. A disagreement can reveal a difference in date, purpose or viewpoint and should prompt investigation. It does not always mean that one source is entirely false.
Two fictional articles repeat the same announcement about a bridge. A dated map and a later travel record offer additional kinds of evidence. Ask whether the question concerns announcement, completion or actual use; those are different claims that may require different records.
Write a bounded explanation
State the claim, identify the relevant evidence and explain the connection. Include uncertainty when the records are incomplete. Separate what a source directly records from what you infer. In a classroom, use original fictional records or material with appropriate rights and context; do not present an invented document as a real historical source.
An original answer might say: “The poster indicates that the route was advertised by that date, but we need a timetable or operating record to establish when regular service began.” This answers within the evidence rather than turning an announcement into proof of operation.
Take these ideas with you.
- A question determines how a source can be used.
- Consider origin, purpose and perspective.
- Explain the connection between evidence and a limited claim.
Check your understanding
Work out each answer before opening the explanation. These checks are not scored or saved.
Does an announcement prove that a service began operating immediately?
No. It establishes that an announcement was made; an operating record or another relevant source would be needed to investigate actual service.
Are three reports copying the same announcement three independent confirmations?
No. Trace the reports to their underlying source before treating agreement as independent corroboration.
What should a source-based explanation contain?
A clear claim, relevant evidence, an explanation of the connection and any important limitation.
