# PWR-124 — Source evaluation and lateral reading: learner worksheet Release: Revision 7T · Full Tutorial Edition Estimated time: Estimated 17 min reading and worksheet pass Difficulty: Introductory Equipment: Basic stationery or digital tools — The fictional claim page CP1 and source cards S1-S4 below; The source-chain worksheet columns built into the fixture; A calculator; The hidden answer key Space: Desk / seated Automated structural checklist: 10 of 10 structural checks present Evidence quality/context: G1; Focused research depth Automated method-quality band: Established Method-rating basis: Structure coverage, instruction/check specificity, alternative distinctness, source troubleshooting, comparison depth and whether purpose/check fields are authored rather than derived. Editorial review: Pending manual editorial sign off ## Before you begin - [ ] I read the tutorial authority and stop conditions. - [ ] I have the required equipment/space or a declared accessible alternative. ## Canonical source context Lateral reading means leaving the claim page, identifying who published it, tracing its number to the earliest accessible data, and checking a genuinely independent source. This pack supplies a closed fictional library-energy packet so no live search or harmful material is needed. The learner separates page count from source independence and updates the exact claim rather than merely rating a publisher. Target outcome: Define source evaluation and lateral reading without inheriting mythology or broader claims. Explain what the current evidence supports and what it does not establish. Use the declared measurement boundary and recognise misleading proxies. Complete only the separately governed capability practice inside its declared limits. Make a retention, transfer, maintenance, provider or stop decision without overclaiming. ### Authority and setup conditions - Do not investigate private people, engage scammers, expose yourself to harmful material, or make a public accusation. - Publisher credibility and claim support are separate; repetition through one citation chain is not triangulation. - This fictional packet does not certify investigative expertise or authorise a consequential public claim. ### Required or supplied materials - The fictional claim page CP1 and source cards S1-S4 below - The source-chain worksheet columns built into the fixture - A calculator - The hidden answer key ### Supplied fixture All documents are fictional. The final three columns are the complete source-chain log. | Source id | Publisher and type | Claim or data | Relationship and incentive | Learner source type | Learner dependency note | Learner claim support note | Learner initial confidence | Learner final confidence and update reason | | --- | --- | --- | --- | --- | --- | --- | --- | --- | | CP1 | Northbank Library news; institutional secondary | Skylights cut daytime lighting electricity by 30% in year one. | Links to S1; celebrates renovation. | [classify] | [trace] | [support/limit] | [0–100 before tracing] | [0–100 plus evidence-linked reason] | | S1 | BrightView Skylights blog; commercial secondary | Repeats 30%; no meter table. | Quotes CP1; marketing incentive. | [classify] | [trace] | [support/limit] | [0–100 before tracing] | [0–100 plus evidence-linked reason] | | S2 | City Facilities meter appendix; official primary | 12-month pre mean 1000 kWh/month; post mean 760 kWh/month. | Earliest meter data; occupancy hours changed. | [classify] | [trace] | [support/limit] | [0–100 before tracing] | [0–100 plus evidence-linked reason] | | S3 | Library social post; institutional secondary | Says about a third less. | Links to S1; same chain. | [classify] | [trace] | [support/limit] | [0–100 before tracing] | [0–100 plus evidence-linked reason] | | S4 | Regional Municipal Audit Office; independent official review | After 10% occupied-hours adjustment: 18% reduction, range 12%-24%. | Uses S2 files; weather and fixture replacement remain limits. | [classify] | [trace] | [support/limit] | [0–100 before tracing] | [0–100 plus evidence-linked reason] | ## 1. Record CP1's exact claim, publisher, cited source and initial confidence from 0… Record CP1's exact claim, publisher, cited source and initial confidence from 0 to 100 before tracing links. Why: “Record CP1's exact claim, publisher, cited source and initial confidence from 0 to 100 before tracing links” creates the auditable value, condition or statement needed for the tutorial’s later comparison and conclusion. Success check: A legible entry directly completes “Record CP1's exact claim, publisher, cited source and initial confidence from 0 to 100 before tracing links” and records the requested condition, decision or boundary without adding a new claim. Accessible alternative: Complete the same research action — “Record CP1's exact claim, publisher, cited source and initial confidence from 0 to 100 before tracing links.” — using speech-to-text, text-to-speech, enlarged text, keyboard-only navigation, shorter work blocks or a support person. Preserve this declared check: “A legible entry directly completes “Record CP1's exact claim, publisher, cited source and initial confidence from 0 to 100 before tracing links” and records the requested condition, decision or boundary without adding a new claim.” Do not convert the research task into capability practice. Alternative relationship: Target preserving when declared check is preserved Learner notes: ________________________________________________________________________________ Completed: [ ] ## 2. Classify every row's source type, incentive and dependency Classify every row's source type, incentive and dependency. Independence concerns the evidence chain, not merely a different web address. Why: “Classify every row's source type, incentive and dependency” isolates the named evidence distinction so the learner can interpret Source evaluation and lateral reading without extending the claim. Success check: The output directly answers “Classify every row's source type, incentive and dependency”, names the relevant distinction and stays within the supplied record. Accessible alternative: Complete the same research action — “Classify every row's source type, incentive and dependency. Independence concerns the evidence chain, not merely a different web address.” — using speech-to-text, text-to-speech, enlarged text, keyboard-only navigation, shorter work blocks or a support person. Preserve this declared check: “The output directly answers “Classify every row's source type, incentive and dependency”, names the relevant distinction and stays within the supplied record.” Do not convert the research task into capability practice. Alternative relationship: Target preserving when declared check is preserved Learner notes: ________________________________________________________________________________ Completed: [ ] ## 3. Trace the number to the earliest primary data and calculate the raw… Trace the number to the earliest primary data and calculate the raw change with numerator and denominator visible. Why: “Trace the number to the earliest primary data and calculate the raw change with numerator and denominator visible” creates the auditable value, condition or statement needed for the tutorial’s later comparison and conclusion. Success check: The work shows the value requested by “Trace the number to the earliest primary data and calculate the raw change with numerator and denominator visible”, retains the supplied units or signs and leaves any unsupported value unknown. Accessible alternative: Complete the same research action — “Trace the number to the earliest primary data and calculate the raw change with numerator and denominator visible.” — using speech-to-text, text-to-speech, enlarged text, keyboard-only navigation, shorter work blocks or a support person. Preserve this declared check: “The work shows the value requested by “Trace the number to the earliest primary data and calculate the raw change with numerator and denominator visible”, retains the supplied units or signs and leaves any unsupported value unknown.” Do not convert the research task into capability practice.

Write a bounded update that separates observation from causal attribution, then record… Write a bounded update that separates observation from causal attribution, then record final confidence and the specific evidence that changed it. Why: “Write a bounded update that separates observation from causal attribution, then record final confidence and the specific evidence that changed it” creates the auditable value, condition or statement needed for the tutorial’s later comparison and conclusion. Success check: A legible entry directly completes “Write a bounded update that separates observation from causal attribution, then record final confidence and the specific evidence that changed it” and records the requested condition, decision or boundary without adding a new claim. Accessible alternative: Complete the same research action — “Write a bounded update that separates observation from causal attribution, then record final confidence and the specific evidence that changed it.” — using speech-to-text, text-to-speech, enlarged text, keyboard-only navigation, shorter work blocks or a support person.
