Arrival Task – Retrieving what an archive record is
An archive holds original documents; a catalogue record describes one of them in fixed fields, and a digitised copy reproduces it, so three different things can share one title.
A transcription is a typed copy made later by someone else, so an error in it is not an error in the original, and the catalogue usually says which you are reading.
Arrival decision: Work from the supplied catalogue extract, or add a second from the approved pack; nobody will ask which you chose.

Starter: Why does an evaluation need a field to point to?
Consider two evaluations of the same record.
Evaluation A: “The passenger list is a reliable source because it is in a national archive.”
Evaluation B: “The passenger list is reliable for the names, ages and stated occupations of those who sailed, because the description field shows it was compiled by the shipping line at the time of the voyage for official purposes; it is less useful for why they came, because the format field shows it records only what the form asked.”
Evaluation B is an evaluation and Evaluation A is a compliment, because B says what the record is reliable for and useful for, and points to the field that supports each claim, whereas A treats the building the document sits in as a guarantee of everything written on it.

I Do: Anatomy of a catalogue record
The diagram above lays out the seven fields of the catalogue record: reference, title, description, date, held by, format and access. Each field answers a different question, and an evaluation earns its judgement by pointing to the field that answers the question the judgement depends on.
Watch the method: I read the model evaluation's first sentence, which says the list was "created by the archive in 1948". I check the description field, which says the list was compiled by the shipping line, and the held-by field, which names the archive as custodian rather than creator. The sentence has confused the record with the document, which is the first error family on the checklist, so I mark it and write the correction beside it, naming both fields. Read the claim, find the field, name the error family, correct.

We Do: Spot the error in three sentences
Sentence 1: “The list is reliable because it was created by the national archive in 1948.”
Sentence 2: “Because the record was digitised in 2018, the information dates from 2018.”
Sentence 3: “The list is useful because it tells us why every passenger chose to come to Britain.”
Spot first: decide what is wrong with each sentence and write the error family and the catalogue field that exposes it on your whiteboard; every table commits at the same time, and only then do we hold the boards up and correct the sentences together.
Evidence check
Sentence 3 is where readings diverge, because the list records stated occupations, which some read as a reason for coming; the format field settles it, since the form asked for occupation and not for motive. A spotted error with a named field is evaluation; one without is a hunch.

I Do: Reliable for what, useful for what
The diagram above plots one record against four questions on two axes, reliable for and useful for, and the point of the grid is that the same document sits high on both axes for one question and low on both for another; reliability and usefulness are properties of a question-and-record pair, never of a record alone.
A model evaluation that ignores the grid reads: “This is an unreliable source because it does not explain why people came.” The list was never asked to explain motive, so its silence is not unreliability; the error confuses a low usefulness score on one question with a low reliability score on all questions.
Repairing it together: rewrite the sentence as “The list is reliable for who sailed but not useful for why they came, because the format field shows the form asked for occupation and not for motive,” which places the record correctly on both axes and names the field that fixes its position.

We Do: Correct the model evaluation together
We correct one sentence on the board before anyone writes: each learner records a corrected version of the same sentence on a whiteboard with the field it now points to, and only when every board is raised do we compare and agree the correction.

Independent Work — Your record: evaluating a digital archive source
Produce one record from the supplied catalogue extract, or from it and a second extract from the pack; both are complete answers.
◆ Supported
Spot one error in the model evaluation with the checklist and name the field that exposes it; an adult may scribe your exact words, which remain yours.
▲ Standard
Spot and correct all three errors, then write a two-sentence evaluation, one for reliability and one for usefulness, each pointing to a field.
★ Stretch
Complete the standard route, then judge how far the digitised copy can stand in for the original and name one thing the record cannot tell.
Check yourself: does every evaluation claim say reliable for what or useful for what?
Check yourself: can you point to a catalogue field for every claim you made?
⏸ Pens down — quick partner check!
Half way through: stop, swap with a partner, and check one thing on the list above together. Then carry on.
WAGOLL — what a good one looks like
A finished row reads: “The list is reliable for who sailed, because the description field shows the shipping line compiled it at the time,” and beside it, “The list is not useful for why they came, because the format field shows the form asked for occupation, not motive.” Two claims, two fields, one record on both axes.

Exit Ticket — Audience receives; influence changes something
Read one claim to a partner or an adult; the listener repeats the field they heard it rest on, in their own words.
If the listener heard a different field from the one you meant, change the wording so that the field is unmistakable; the change is your influence and belongs to you rather than to the listener.
✅ Complete
Hand in your record and tick the learner confirmation on your sheet. That is the lesson done.
