Space: Desk / seated Automated structural checklist: 10 of 10 structural checks present Evidence quality/context: G1; Deep 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 This lesson builds a household information fallback for a six-hour internet loss. You will specify a needed bulletin; verify local broadcast plus telephone sources; print an accessible tuning card; rehearse a timed internet-down lookup; reject stale or unattributed messages; draw a radio-unavailable card; refresh batteries, frequencies and contact details afterward. Target outcome: An intended user retrieves one dated official Merehaven bulletin within 15 minutes via an offline channel, identifies issuer plus time, then reaches a paper contact when radio becomes unavailable. ### Authority and setup conditions - Choose a low-risk information or communication function; exclude medicine, utilities and other hazardous systems. - Verify official source ownership, local relevance and current date. - Agree who needs access, what privacy information is necessary and what condition transfers responsibility to outside help. ### Required or supplied materials - A fictional essential function card: “Receive verified official updates for six hours without home internet.” - Primary smartphone/data route, battery radio or official broadcast route, paper official numbers and a support-person route—all used only as a tabletop configuration. - Fallback matrix for capacity, independence, access, switch time, maintenance, safe stop and recovery. ## 1. Write the bulletin contract State: the intended user will obtain one verified Merehaven local bulletin within 15 minutes during a fictional six-hour loss of home internet. Why: A precise message and deadline prevent vague claims that having a radio is enough. Success check: Contract fields name user, locality, source quality, delay plus six-hour window. Accessible alternative: Complete “State: the intended user will obtain one verified Merehaven local bulletin within 15 minutes during a fictional six-hour loss of home internet.” in shorter passes, or use keyboard input, dictation or a support person, while preserving this success check: “Contract fields name user, locality, source quality, delay plus six-hour window.” Test reach, grip, hearing, vision, communication and cognitive load with the intended user’s ordinary aids. Alternative relationship: Target preserving when declared check is preserved Learner notes: ________________________________________________________________________________ Completed: [ ] ## 2. Verify official sources Copy fictional public broadcaster name, frequency, bulletin times plus dated telephone number from sponsor card; reject reposts or undated screenshots. Why: An offline message is useful only when its issuer and currency can be checked. Success check: Both broadcast plus telephone entries show issuer, date and locality. Accessible alternative: Replace small or visual-only information with enlarged text, high-contrast display, spoken description or tactile/verbal cueing while preserving the same decision and success check. Make human or public support an explicit valid fallback; do not require solitary operation. Alternative relationship: Target preserving when declared check is preserved Learner notes: ________________________________________________________________________________ Completed: [ ] ## 3. Inspect channel requirements For each channel, write requirements: phone uses router or mobile data; radio uses batteries, reception plus tuning; paper contact needs an available telephone or support person. Why: Concrete requirements reveal why a different device may still fail in the same outage. Success check: The sheet identifies which internet-loss condition affects each channel. Accessible alternative: Complete the same research action — “For each channel, write requirements: phone uses router or mobile data; radio uses batteries, reception plus tuning; paper contact needs an available telephone or support person.” — using speech-to-text, text-to-speech, enlarged text, keyboard-only navigation, shorter work blocks or a support person. Preserve this declared check: “The sheet identifies which internet-loss condition affects each channel.” Do not convert the research task into capability practice. Alternative relationship: Target preserving when declared check is preserved Learner notes: ________________________________________________________________________________ Completed: [ ] ## 4. Make the tuning card Print frequency, power control, volume control, bulletin times, radio location plus paper telephone option in an accessible user format. Why: Instructions stored online disappear at exactly the moment this fallback is needed. Success check: Intended user locates radio, then tunes it from printed instructions alone. Accessible alternative: Complete “Print frequency, power control, volume control, bulletin times, radio location plus paper telephone option in an accessible user format.” in shorter passes, or use keyboard input, dictation or a support person, while preserving this success check: “Intended user locates radio, then tunes it from printed instructions alone.” Test reach, grip, hearing, vision, communication and cognitive load with the intended user’s ordinary aids. Alternative relationship: Target preserving when declared check is preserved Learner notes: ________________________________________________________________________________ Completed: [ ] ## 5. Declare the change cue When ‘official page unavailable for five minutes’ appears, begin radio lookup; do not wait for battery or phone to fail as well. Why: A visible cue prevents delay and repeated troubleshooting of the unavailable internet page. Success check: The cue, clock start and first radio action are written in one line. Accessible alternative: Replace small or visual-only information with enlarged text, high-contrast display, spoken description or tactile/verbal cueing while preserving the same decision and success check. Make human or public support an explicit valid fallback; do not require solitary operation. Alternative relationship: Target preserving when declared check is preserved Learner notes: ________________________________________________________________________________ Completed: [ ] ## 6. Rehearse the radio lookup Leave real internet connected. Turn over fictional outage card, start a timer, then use only printed instructions to locate scheduled bulletin. Why: A simulation can expose tuning, reach and hearing barriers without causing a real outage. Success check: User finds a channel within 15 minutes or records an exact access failure. Accessible alternative: Complete “Leave real internet connected. Turn over fictional outage card, start a timer, then use only printed instructions to locate scheduled bulletin.” in shorter passes, or use keyboard input, dictation or a support person, while preserving this success check: “User finds a channel within 15 minutes or records an exact access failure.” Put the switch instructions at the point of use in large print, pictures, braille, audio and any needed languages. Alternative relationship: Target preserving when declared check is preserved Learner notes: ________________________________________________________________________________ Completed: [ ] ## 7. Check bulletin provenance Before accepting a message, state broadcaster, locality, issue time plus currency for this exercise window. Why: Receiving sound is different from receiving a verified, relevant update. Success check: All four provenance fields match the supplied sponsor card. Accessible alternative: Complete “Before accepting a message, state broadcaster, locality, issue time plus currency for this exercise window.” in shorter passes, or use keyboard input, dictation or a support person, while preserving this success check: “All four provenance fields match the supplied sponsor card.” Test reach, grip, hearing, vision, communication and cognitive load with the intended user’s ordinary aids. Alternative relationship: Target preserving when declared check is preserved Learner notes: ________________________________________________________________________________ Completed: [ ] ## 8. Draw radio unavailable Turn over a radio-unavailable card; locate printed official number plus support contact; state when outside help becomes correct. Why: The exercise must end safely when neither self-managed information channel works. Success check: The user reaches the paper-contact instruction without inventing another device or unsafe workaround. Accessible alternative: Complete “Turn over a radio-unavailable card; locate printed official number plus support contact; state when outside help becomes correct.” in shorter passes, or use keyboard input, dictation or a support person, while preserving this success check: “The user reaches the paper-contact instruction without inventing another device or unsafe workaround.” Make human or public support an explicit valid fallback; do not require solitary operation. Alternative relationship: Target preserving when declared check is preserved Learner notes: ________________________________________________________________________________ Completed: [ ] ## 9. Refresh after rehearsal Record elapsed time; recharge only under manufacturer instructions; recheck frequency or number dates; initial a next quarterly check. Why: Batteries, schedules and public contact details age even when the radio is untouched. Success check: Card fields show test result, refresh action, checker plus next date. Accessible alternative: Complete the same research action — “Record elapsed time; recharge only under manufacturer instructions; recheck frequency or number dates; initial a next quarterly check.” — using speech-to-text, text-to-speech, enlarged text, keyboard-only navigation, shorter work blocks or a support person. Preserve this declared check: “Card fields show test result, refresh action, checker plus next date.” Do not convert the research task into capability practice. Alternative relationship: Target preserving when declared check is preserved Learner notes: ________________________________________________________________________________ Completed: [ ] ## Reflection What changed? ________________________________________________________________________________ What remains difficult? ________________________________________________________________________________ What will I repeat, adapt, ask for help with, or stop? ________________________________________________________________________________ --- Completion of this worksheet demonstrates tutorial participation only.
