Separate supported statements, inference, and unverified assertions in a draft.

Supplied materials

  • Original fictional packet. Source A, dated pilot log: “At one two-hour archive session, 12 volunteers tried the index; 9 located their assigned item.” Source B, coordinator note: “Items varied in difficulty. No prior method was tested alongside the index, and no later follow-up occurred.” Draft: “The index permanently halves search time for every archive user and is approved for expansion.”
  • Paper and pencil; spoken responses are welcome.

Learn the idea

An evidence audit checks each meaningful clause against a source. Ask who, when, what was measured, whether a comparison exists, and what status is established. A supports nine of twelve locating assigned items in one session. B supplies difficulty and design limits. Neither gives search times, permanent effects, all users, or approval.

A source link or citation does not make a claim supported if the source lacks the claimed information. Label a practical interpretation as an inference and a future action as a proposal. The appropriate revision is not that the index failed; it is that the packet reports limited item-finding results and leaves speed, retention, causal benefit, and expansion approval unestablished.

  1. Break the draft into permanent, halves time, every user, and approval claims.
  2. Match each to A or B, marking unsupported clauses explicitly.
  3. Write a supported finding with its session scope.
  4. Add design limits and identify any next step as a proposal.
Worked example

See the method in action

The pilot log records nine of twelve volunteers locating assigned items during one two-hour session. Varying item difficulty and no comparison method limit attributing success to the index. Search-time reduction, later effects, broad generalization, and expansion approval are not established by the packet.

Which audit conclusion is correct?

Feedback appears here after you check. This is practice, not a graded school assessment.

See the answer and explanation

The cited packet records limited item-finding outcomes, but lacks time, later-effect, comparison, and approval evidence.

The audit identifies what was actually recorded and what was not. Missing measures or approval do not prove an opposite outcome.

Take it further

Add Source C: “The coordinator approved a one-shelf trial next month; search times will be recorded.” Model: the packet now supports approval for that limited future trial, not approval for all-shelf expansion or an already measured time saving. Keep timing and approved scope precise.
