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 teaches the full provider-led community-sensing method: establish an accountable sponsor and decision purpose, involve affected communities before collection, set a protocol and metadata, and protect sensitive places and people. You will also train observation and quality checks, measure participation and coverage bias, verify signals, connect findings to an accountable response, return results to contributors, and govern access, secondary use and deletion. Practice uses fictional records only. Target outcome: With an authorised facilitator, the learner completes a fictional sensing-project protocol and quality review that traces one observation from collection to verification, response, contributor feedback and deletion. ### Authority and setup conditions - Confirm the project, contributors, coordinates, species and institutions are entirely fictional. - Write the decision purpose and accountable sponsor before opening the packet. - Set collection limits, verification, deletion and stop rules, including no real field visit or sensing. ### Required or supplied materials - Authorised facilitator and a fictional flood-puddle observation project in the imaginary town of Merehaven. - Fictional sponsor/decision card, protocol, metadata form, consent/privacy and sensitive-location screen. - Twenty supplied observations.

Define sponsor and decision Name the accountable body, exact question, intended decision, jurisdiction, duration and non-uses. Why: Data without a decision owner can extract effort without response. Success check: The purpose is narrow and the sponsor can act or explain why not. Accessible alternative: Ask the qualified provider to adapt positioning, cue modality, pace, interface or rest while preserving this step’s declared check: “The purpose is narrow and the sponsor can act or explain why not.” If an adaptation changes the measured task or configuration, record it as a different configuration rather than an equivalent attempt. Alternative relationship: Conditional equivalence requires target and configuration check Learner notes: ________________________________________________________________________________ Completed: [ ] ## 2. Involve affected interests Identify residents, land/rightsholders, workers, accessibility groups, privacy interests and absent people before protocol design. Why: Community sensing is not legitimate because volunteers are available. Success check: The design records influence and unresolved representation. Accessible alternative: Ask the qualified provider to adapt positioning, cue modality, pace, interface or rest while preserving this step’s declared check: “The design records influence and unresolved representation.” If an adaptation changes the measured task or configuration, record it as a different configuration rather than an equivalent attempt. Alternative relationship: Conditional equivalence requires target and configuration check Learner notes: ________________________________________________________________________________ Completed: [ ] ## 3. Specify observation protocol Define what counts as an observation, units/categories, time window, location precision, equipment, repeats and invalid cases. Why: Comparable records require a shared method. Success check: Two fictional contributors would record the same event similarly. Accessible alternative: Ask the qualified provider to adapt positioning, cue modality, pace, interface or rest while preserving this step’s declared check: “Two fictional contributors would record the same event similarly.” If an adaptation changes the measured task or configuration, record it as a different configuration rather than an equivalent attempt. Alternative relationship: Conditional equivalence requires target and configuration check Learner notes: ________________________________________________________________________________ Completed: [ ] ## 4. Set consent and data lifecycle Separate participation, location, image, contact, publication and secondary-use choices; define access, correction, retention and deletion. Why: Open collection is not blanket permission. Success check: Every field and use has authority and an expiry. Accessible alternative: Ask the qualified provider to adapt positioning, cue modality, pace, interface or rest while preserving this step’s declared check: “Every field and use has authority and an expiry.” If an adaptation changes the measured task or configuration, record it as a different configuration rather than an equivalent attempt. Alternative relationship: Conditional equivalence requires target and configuration check Learner notes: ________________________________________________________________________________ Completed: [ ] ## 5. Protect people and sensitive places Remove exact homes, protected sites, vulnerable populations and ecological locations unless specifically authorised; provide a no-collection rule. Why: Precision can create privacy, safety or ecological harm. Success check: Sensitive records are coarsened, restricted or excluded. Accessible alternative: Ask the qualified provider to adapt positioning, cue modality, pace, interface or rest while preserving this step’s declared check: “Sensitive records are coarsened, restricted or excluded.” If an adaptation changes the measured task or configuration, record it as a different configuration rather than an equivalent attempt. Alternative relationship: Conditional equivalence requires target and configuration check Learner notes: ________________________________________________________________________________ Completed: [ ] ## 6. Run quality checks Validate time, location class, protocol fit, duplicates, equipment/observer notes and plausibility; keep rejected records and reasons visible. Why: Cleaning can hide inconvenient or biased data. Success check: Each record is valid, uncertain or excluded with a reason. Accessible alternative: Ask the qualified provider to adapt positioning, cue modality, pace, interface or rest while preserving this step’s declared check: “Each record is valid, uncertain or excluded with a reason.” If an adaptation changes the measured task or configuration, record it as a different configuration rather than an equivalent attempt. Alternative relationship: Conditional equivalence requires target and configuration check Learner notes: ________________________________________________________________________________ Completed: [ ] ## 7. Measure participation and coverage Map who reported, where and when, concentration, gaps and access barriers; do not treat empty space as absence. Why: Volunteer data often cluster by access and motivation. Success check: The coverage table names North Path concentration and every unobserved area or time. Accessible alternative: Ask the qualified provider to adapt positioning, cue modality, pace, interface or rest while preserving this step’s declared check: “The coverage table names North Path concentration and every unobserved area or time.” If an adaptation changes the measured task or configuration, record it as a different configuration rather than an equivalent attempt. Alternative relationship: Conditional equivalence requires target and configuration check Learner notes: ________________________________________________________________________________ Completed: [ ] ## 8. Verify before response Compare a sample with authorised reference or trained review, record false positives/negatives and uncertainty. Why: Raw reports are signals, not facts. Success check: Only verified evidence reaches the fictional decision route. Accessible alternative: Ask the qualified provider to adapt positioning, cue modality, pace, interface or rest while preserving this step’s declared check: “Only verified evidence reaches the fictional decision route.” If an adaptation changes the measured task or configuration, record it as a different configuration rather than an equivalent attempt. Alternative relationship: Conditional equivalence requires target and configuration check Learner notes: ________________________________________________________________________________ Completed: [ ] ## 9. Close response and feedback Record what the sponsor did, why, how contributors were informed and how corrections or complaints are handled. Why: Participation should have an accountable consequence. Success check: Contributors can trace data to response or explained non-action. Accessible alternative: Ask the qualified provider to adapt positioning, cue modality, pace, interface or rest while preserving this step’s declared check: “Contributors can trace data to response or explained non-action.” If an adaptation changes the measured task or configuration, record it as a different configuration rather than an equivalent attempt. Alternative relationship: Conditional equivalence requires target and configuration check Learner notes: ________________________________________________________________________________ Completed: [ ] ## 10. Review reuse and retire At the endpoint, review value, harm, bias and unresolved need; delete, restrict or renew under fresh authority. Why: Projects should not collect forever by inertia. Success check: No data remains active beyond purpose without a governed decision. Accessible alternative: Ask the qualified provider to adapt positioning, cue modality, pace, interface or rest while preserving this step’s declared check: “No data remains active beyond purpose without a governed decision.” If an adaptation changes the measured task or configuration, record it as a different configuration rather than an equivalent attempt. Alternative relationship: Conditional equivalence requires target and configuration check 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.
