Goal or Shortcut?

Distinguish a legitimate learning goal from a shortcut, design an appropriate AI role, and retain responsibility for the final work.

Scenario: Your teacher asks for a five-minute history presentation explaining why the Salt March mattered. The marking criteria require an explanation in your own words, two reliable sources and a short question-and-answer discussion. You are behind schedule and a chatbot offers to write a polished script immediately.

1. Name the real goal

Which statement best defines the actual learning goal?

0/2 — Produce a polished five-minute script as quickly as possible.
This treats the deliverable as the goal and ignores the understanding the teacher will test.
2/2 — Understand and explain why the Salt March mattered, using evidence and my own reasoning.
Strong. It identifies the knowledge, reasoning and evidence the student must demonstrate.
1/2 — Collect as many historical facts as possible, even if I cannot explain how they connect.
Facts may help, but the assignment requires explanation and connected reasoning, not a list.

Model reasoning: The goal is to understand and explain historical significance using evidence. A finished script is an output, not the learning goal.

Discussion prompt: Could a polished script still fail the assignment even if every sentence is grammatically correct?

2. Choose an appropriate AI role

What is the strongest way to use AI while preserving the learning goal?

0/2 — Ask AI to write the complete script, memorise it and disclose that AI wrote it.
Disclosure is important, but it does not repair the loss of the learning task.
2/2 — Ask AI for planning questions and a possible structure, then verify sources and write the explanation myself.
Strong. AI supports the process while the student retains authorship, verification and understanding.
0/2 — Use an AI summary, change a few words and rely on the teacher not asking detailed questions.
Minor wording changes do not create genuine understanding or authorship.

Model reasoning: AI may support planning, questioning and feedback, but the student must verify sources and create the explanation.

Discussion prompt: Is disclosure enough to make full substitution acceptable? Why or why not?

3. Build a learning-support prompt

Select the instructions that belong in a responsible prompt. Add one sentence of your own if useful.

Required elements: Ask me clarifying questions before suggesting an outline., Suggest a structure that connects causes, events and consequences., Mark claims or quotations that need independent verification.

Model reasoning: The prompt should keep the student in control, request structure rather than a final submission, and explicitly require uncertainty and source checking.

Discussion prompt: Which prompt instruction most clearly protects the learning goal?

4. Make and communicate the decision

What should the student do next?

2/2 — Use the planning prompt, verify all evidence, write my own presentation and record/disclose the assistance as required.
Strong. This combines appropriate use, verification, authorship and disclosure.
1/2 — Do not use any AI because all AI support is automatically cheating.
This is safe but overgeneralised. The school permits limited support that preserves the learning goal.
0/2 — Use the complete AI script because a disclosure statement makes any use acceptable.
Disclosure does not make substitution consistent with the assignment's learning goal.

Model reasoning: Use AI only for permitted planning support, verify sources, create the final explanation independently and disclose the actual assistance.

Discussion prompt: When might deciding not to use AI be reasonable even if limited AI use is permitted?

AI Limitations Challenge

Recognise missing context, distinguish fluency from evidence and design a proportionate verification plan.

Scenario: A student asks two AI systems why a city became much hotter this year. System A says the main cause is the urban heat-island effect. System B says the main cause is El Niño. Both answers are detailed and confident, but the prompt does not name the city, dates, measurement method or comparison period.

1. Find the missing context

Which information is necessary before either explanation deserves high confidence? Select all that apply.

Strong selection: The city or region being discussed., The dates and comparison period., Whether the claim concerns daily highs, averages, surface temperature or another measure., Local observations and relevant weather or land-use data.

Model reasoning: The cause cannot be assessed without place, period, measurement and local evidence. Technical language does not supply missing context.

Discussion prompt: Why can two generally plausible explanations both be poorly supported in a specific case?

2. Calibrate confidence

What confidence level is justified at this stage?

0/2 — High confidence in System A because its explanation is more detailed.
Detail and fluency do not establish that the explanation fits the unnamed city and period.
2/2 — Low confidence in a specific cause; treat both as hypotheses requiring local evidence.
Strong. This separates plausibility from case-specific support.
0/2 — Combine the answers and say both were equally responsible.
Averaging unsupported claims does not create evidence about their relative contribution.
1/2 — Use System A but add the word 'probably'.
A qualifier helps, but it still privileges one explanation without a basis.

Model reasoning: Both explanations are plausible hypotheses. Neither should be presented as the main cause until local evidence is checked.

Discussion prompt: How should a student communicate uncertainty without pretending to know nothing?

3. Choose a verification plan

Which checks would meaningfully reduce the uncertainty?

Strong selection: Compare local meteorological records across the relevant periods., Check reliable land-use and urban-development information for the city., Check reputable climate data explaining El Niño's regional effects during the period.

Model reasoning: Use local observations, land-use evidence and reliable climate data. Repetition by the same model or on social media is not independent confirmation.

Discussion prompt: When can asking an AI again be useful, and why is it not independent verification?

4. Decide what to write

Which response is most responsible?

0/2 — System A is correct: cities are hotter because of buildings and roads.
This turns a general mechanism into an unsupported case-specific conclusion.
2/2 — Both mechanisms could matter, but the information provided is insufficient to identify the main cause; local data must be checked.
Strong. It communicates useful possibilities and calibrated uncertainty.
1/2 — AI cannot answer questions about weather, so reject every part of both outputs.
The outputs contain plausible concepts, but their application to this case is unverified.

Model reasoning: Explain that both mechanisms are possible, avoid choosing a main cause and identify the evidence required for a stronger conclusion.

Discussion prompt: Can a useful answer be given before the cause is known with confidence?

Hallucination Detective

Distinguish verified, partly supported, unsupported and fabricated claims using an evidence pack.

Scenario: An AI-generated draft about education in India includes a memorable quotation attributed to Rabindranath Tagore, a percentage about teenage AI use, a census claim and a general warning about invented citations. The draft sounds authoritative and includes references.

1. Classify the claims

Use the evidence notes to classify every claim.

Fabricated — Tagore wrote: “Education is the lighting of a fire, not the filling of a vessel.”
The quotation and attribution are presented as exact, but the cited source cannot be found and the attribution conflicts with available references.
Verified — India's literacy rate increased between the 2001 and 2011 censuses.
The direction of change is directly supported by the identified official data.
Unsupported — Seventy-three percent of Indian teenagers use AI every day (UNESCO 2023, p. 42).
The claim may or may not be true, but the supplied citation does not support it.
Partly supported — Generative AI can support brainstorming but may also produce inaccurate citations.
The general proposition is well supported, but its broad wording needs context and should not be treated as a quantified universal claim.

Model reasoning: Classify the exact claim being made. Verification requires the source to exist and actually support that claim.

Discussion prompt: Why is a citation mismatch not automatically proof that the underlying statistic is false?

2. Set the verification priority

Which items require the most urgent checking before submission?

2/2 — Check the exact quotation and the 73% statistic first.
Strong. Both are precise claims carrying apparent authority and high credibility risk.
0/2 — Check only the spelling and grammar because the citations look professional.
Presentation quality does not establish factual support.
1/2 — Check the broad brainstorming claim first and leave the quotation for later.
The broad claim needs context, but the exact quotation and statistic carry a more immediate verification risk.

Model reasoning: The quotation and percentage require immediate verification or removal because they are precise, repeatable and falsely supported.

Discussion prompt: Would the order change if the statistic affected a health or safety decision?

3. Repair the draft

Which actions should the student take? Select all that apply.

Strong selection: Remove the quotation unless a reliable primary or scholarly source is found., Remove or clearly mark the statistic as unverified until a supporting study is located., Cite the official census table for the literacy claim.

Model reasoning: Remove or qualify unsupported content and replace vague references with sources that directly support the exact claim.

Discussion prompt: When is it acceptable to keep an unverified idea as a question for further research?

4. Decide whether to use the draft

What is the strongest final decision?

0/2 — Submit it unchanged because the draft includes references.
References that do not support the claims create false assurance.
2/2 — Revise it claim by claim, keep only supported content and record/disclose the AI assistance.
Strong. This preserves useful work while repairing evidence and authorship.
1/2 — Reject every sentence because one quotation was fabricated.
Caution is reasonable, but supported claims can be retained after independent checking.

Model reasoning: Revise the draft: retain verified content, qualify broad claims, remove unsupported or fabricated material and disclose AI assistance if required.

Discussion prompt: Is rejecting the entire draft always necessary when some claims are supported?

Source Verification Trail

Identify primary and independent sources, recognise derivative repetition and document an evidence trail with dates and unresolved uncertainty.

Scenario: A widely forwarded message says: “All schools will close tomorrow because air pollution has reached an emergency level.” An AI summary repeats the statement and lists several links. Students are deciding whether to forward it to classmates.

1. Choose the strongest sources

Which sources should be checked first to establish the current claim?

Strong selection: A dated notice on the school's official website or verified school channel., A current pollution-control or education-authority notice for the relevant location.

Model reasoning: Check the current official school and relevant authority notices first. Record their dates, scope and any differences.

Discussion prompt: Can an official source still be wrong or outdated? What should be recorded?

2. Detect circular and outdated sourcing

Classify each source relationship.

Primary/current — A school notice dated today, signed by the principal and posted on the official domain.
It has direct authority over the school's operation and is current.
Independent corroboration — A local newspaper article that links to today's education-authority order and quotes the order accurately.
It independently reports and links the authoritative order.
Circular or derivative — A blog cites a news aggregator; the aggregator cites the same viral message.
Multiple pages repeat the same unsupported origin.
Outdated for this claim — A genuine school-closure order from a previous pollution episode two years ago.
Authenticity does not make an old order evidence of a current closure.

Model reasoning: Authority, independence, date and scope all matter. Repetition is not corroboration when sources trace back to the same unsupported post.

Discussion prompt: Why can a real document be irrelevant evidence?

3. Build the evidence trail

Select what a reliable verification record should contain.

Required elements: Write the exact claim being checked., Record the date, time and location covered by each source., Link or identify the primary current notice., State any unresolved conflict or missing information.

Model reasoning: Document the exact claim, current authoritative evidence, dates and any uncertainty. Independent corroboration strengthens the trail; counting repetitions does not.

Discussion prompt: What minimum record would let a classmate verify your conclusion independently?

4. Decide what to send

No current official closure notice can be found. What should the student do?

0/2 — Forward it with “not sure if true” so classmates can decide.
Forwarding still amplifies an unverified alarm and may detach the warning from your qualifier.
2/2 — Do not forward it as fact; point classmates to official channels and alert a responsible adult if it is spreading.
Strong. This limits harm while preserving a route to authoritative confirmation.
1/2 — Announce that school will definitely remain open because no notice was found.
Lack of a notice is not definitive proof. The responsible response should preserve uncertainty.

Model reasoning: Do not forward the alarm as fact. State that it is unverified, direct classmates to official channels and alert a responsible school adult if the message is spreading.

Discussion prompt: What wording avoids both panic and false reassurance?

Bias and Fairness Explorer

Recognise that changing a threshold changes outcomes but may not repair biased inputs, and identify stakeholders, remedies and appeal mechanisms.

Scenario: A school uses a score to shortlist students for a scholarship interview. The score rewards grades, attendance and extracurricular participation. Some students have had fewer opportunities to join paid clubs or travel to competitions. The tool does not make the final award, but students below the threshold are not interviewed.

1. Explore the threshold

Move the threshold and observe selection rates and qualified students missed. Then choose the strongest conclusion.

1/2 — Choose whichever threshold selects the same number from each group; that proves the system is fair.
Equal counts can be informative, but they do not prove the features or individual decisions are fair.
2/2 — Threshold changes affect outcomes, but they cannot by themselves fix a score that may encode unequal access; the features and missed students need review.
Strong. You distinguish a decision rule from the quality and fairness of the inputs.
0/2 — Use the threshold that selects the most students because a higher selection rate is always fairer.
Overall selection rate alone does not address unequal errors, limited places or the relevance of the score.

Model reasoning: Inspect selection and missed-qualified rates by group, but also review whether extracurricular access is an appropriate and equitably available feature.

Discussion prompt: Could lowering the threshold help one group while still leaving the underlying feature unfair?

2. Identify affected people

Who must be considered when reviewing this system?

Strong selection: Students selected and not selected, including those with fewer opportunities., Families who may need to understand or challenge the process., Teachers and the scholarship committee accountable for the decision process., The tool provider, which should explain design assumptions and limitations.

Model reasoning: Review must include affected students and families, accountable school decision-makers and the provider responsible for the tool's design.

Discussion prompt: Which stakeholder may know about barriers that are invisible in the dataset?

3. Choose proportionate remedies

Which controls could improve the process before use?

Strong selection: Review whether extracurricular participation is relevant and whether opportunity differences require removal or adjustment., Test selection and error patterns by relevant groups, with a clear purpose and safeguards., Require trained human review of borderline and adverse cases., Give students a clear explanation and a way to provide missing context or appeal.

Model reasoning: Review questionable features, audit outcomes, retain accountable human review and provide explanation and appeal. Data collection must be necessary and protected.

Discussion prompt: Why is an appeal mechanism not a substitute for improving the model itself?

4. Make the deployment decision

What is the strongest current decision?

0/2 — Use the score as the automatic shortlist because a human makes the final award later.
The shortlist already determines who receives consideration, so the automated gate is consequential.
2/2 — Pause automatic use, revise and test the model, then use it only as one input with human review, explanation and appeal.
Strong. This recognises both technical and procedural safeguards.
1/2 — Delete every use of data in scholarship decisions and select students randomly.
This avoids the tool's risks but does not create a defensible scholarship process. Relevant evidence may still be used responsibly.

Model reasoning: Do not use the score as an automatic gate. Revise and test the features, require human review and explanation, and create a meaningful appeal route.

Discussion prompt: What evidence would justify a future decision to use the tool more broadly?

Privacy Choice Lab

Apply purpose, permission, minimisation and device-safety checks before entering information into an AI system.

Scenario: Students are creating a class exhibition poster with an AI design tool. The tool invites them to upload photographs, notes and location details to personalise the result. The group is working on a shared school computer.

1. Classify the information

Classify each item for this task. Assume the tool's retention and training practices have not yet been checked.

Generally safe for this purpose — The public URL of a museum page used as a design reference.
A public reference URL is generally low risk, subject to normal source and copyright checks.
Permission or school check required — A class photograph showing identifiable students.
Identifiable images of other students require consent and compliance with school rules and tool terms.
Unsafe or high risk to enter — A student's live home location so the design can show a nearby landmark.
It is sensitive and unnecessary for the stated purpose.
Unsafe or high risk to enter — A classmate's health condition mentioned in project notes.
Health information is highly sensitive and should not be entered for this purpose.
Generally safe for this purpose — A teacher-provided anonymous list of colour preferences with no names or identifiers.
Purpose-limited anonymous data prepared by the teacher is generally appropriate.
Unsafe or high risk to enter — A spreadsheet containing student names, marks and attendance.
The data is sensitive, belongs to multiple people and is unnecessary.

Model reasoning: Use only information necessary for the task, with appropriate permission and an understanding of how the tool stores or reuses it.

Discussion prompt: Why can a public photograph still require care when uploading it to a new tool?

2. Respond to the photo request

The tool produces better layouts if a class photograph is uploaded. What should the group do?

0/2 — Upload it because the project is educational and the image already exists.
Educational purpose does not automatically authorise a new external upload or reuse.
2/2 — Use a lower-risk alternative; upload only if the school approves, the tool is appropriate and every affected person has the required consent.
Strong. This preserves the goal while respecting necessity, tool risk and affected people.
0/2 — Crop one student out and upload the rest without asking because fewer people are visible.
Reducing the number of people does not create consent for those who remain identifiable.

Model reasoning: Do not upload the class photo until school rules, tool practices and consent are satisfied. Use a lower-risk alternative where possible.

Discussion prompt: What lower-risk substitute could achieve the design goal?

3. Apply the privacy checklist

Select the checks the group should complete before entering any non-public information.

Required elements: Confirm the information is necessary for a clear learning purpose., Check permission, consent and school rules for information about other people., Use the least detailed or least identifiable information that will work., Sign out and avoid saving sensitive information on the shared device.

Model reasoning: Confirm necessity and permission, minimise data, understand tool practices and secure the shared device session.

Discussion prompt: Which check is easiest for students to forget on a shared device?

4. Make the final decision

Which decision best fits the project?

2/2 — Proceed using public references and anonymous teacher-prepared material; ask the teacher before any personal-data upload.
Strong. This is proportionate and keeps a clear escalation route.
1/2 — Avoid every digital tool because privacy can never be managed.
This is cautious but unnecessarily absolute. Low-risk, purpose-limited use can be appropriate.
0/2 — Upload all available material, then delete the final poster after submission.
Deleting the output does not control what the tool retained or reused.

Model reasoning: Proceed with public or teacher-prepared anonymous materials, avoid unnecessary personal data and ask a responsible adult when permission or tool practices are unclear.

Discussion prompt: When should a student ask a teacher rather than deciding alone?

Human Override Challenge

Identify consequential decision points requiring accountable human review, evidence, explanation and appeal.

Scenario: A school writing checker gives a student's essay a 91% 'AI-generated' score. The teacher notices that the student's style changed from earlier work. The checker provides no source match or sentence-level explanation. The student says they used accessibility support and has notes and earlier drafts.

1. Choose the immediate action

What should happen first?

0/2 — Issue the penalty immediately because 91% is above 90%.
A confidence score is not proof and the tool provides no explanation or validated threshold for this context.
2/2 — Pause the accusation, review the work and process, and give the student a fair opportunity to explain and provide drafts.
Strong. The tool triggers inquiry, not an automatic adverse decision.
1/2 — Ignore the flag completely because AI detectors are never useful.
The flag may justify a proportionate review, but not a penalty by itself.

Model reasoning: Pause any accusation, preserve the output as one piece of information, review the assignment context and allow the student to explain and provide evidence.

Discussion prompt: What harm can occur before a formal penalty is imposed?

2. Choose the evidence for review

Which evidence should the human reviewer consider?

Strong selection: The student's notes, drafts, revision history and ability to explain the argument., The assignment rules and what AI or accessibility support was permitted., The checker's documented limitations, validation evidence and error rates for comparable students and tasks., Relevant accessibility or language-support context, handled confidentially.

Model reasoning: Use process evidence, assignment rules, tool limitations and relevant protected context. Rumour and a single unexplained score are insufficient.

Discussion prompt: How should confidential accessibility information be handled in the review?

3. Assign accountable roles

Which people or roles should be part of a fair process?

Strong selection: The teacher, who understands the assignment and student work., The student, with a chance to explain and provide evidence., An appropriate academic or school lead for serious or disputed findings., A relevant accessibility or safeguarding professional where necessary and authorised.

Model reasoning: The process needs accountable school humans, student participation and relevant support. A tool cannot hold responsibility or hear an appeal.

Discussion prompt: Who should have authority to reverse an initial finding?

4. Design the appeal route

What appeal mechanism is strongest?

0/2 — Allow an appeal only if the student can prove the detector is technically defective.
This places an unrealistic burden on the student and ignores errors in context or process.
2/2 — Explain the concern and evidence, allow the student to respond, and provide review by an appropriate human who can change the decision.
Strong. The route is informed, participatory and capable of remedy.
0/2 — Let the same automatic checker run the essay again and call the second score an appeal.
Repeating the same mechanism is not independent human review.

Model reasoning: Provide the reason, evidence used and a route to an independent or more senior human review where the student can add context and challenge errors.

Discussion prompt: What information should the student receive before deciding whether to appeal?

AI Disclosure Decision

Distinguish assistance from substitution, respect teammate expectations and create a disclosure that describes purpose, contribution, checking and human responsibility.

Scenario: Four students prepare a science presentation. They used a chatbot to brainstorm topics, suggest an outline and edit sentences. One student also used it to generate all calculations without checking them, and another created an AI image without telling the group. The teacher permits limited AI assistance when it is checked and disclosed.

1. Classify the AI uses

Classify each use in this assignment context.

Assistance — The group asks for possible topic angles, then chooses and develops one themselves.
The tool helps generate possibilities while the group makes and develops the decision.
Substitution — A complete analysis is generated and submitted unchanged as the group's reasoning.
The AI replaces the core work being assessed.
Assistance — After writing a draft, students use sentence-level editing suggestions and accept only changes they understand.
The students retain the ideas and make informed editing decisions.
Depends on checks, permission or disclosure — An AI image is added without checking licence, accuracy or teammate agreement.
Use may be acceptable after checks and group agreement; the current process is incomplete.
Substitution — The AI performs every calculation and no student checks or understands the method.
The tool replaces assessed reasoning and creates an accuracy risk.

Model reasoning: The boundary depends on the learning goal, school rules, human understanding, verification and the extent of AI contribution.

Discussion prompt: Can the same AI action be assistance in one assignment and substitution in another?

2. Respect the group

What should happen before the presentation is submitted?

0/2 — Say nothing because each student controls the tools used on their own section.
The final submission represents the group and may expose all members to academic-integrity or accuracy consequences.
2/2 — Tell the group, review the calculations and image, remove or correct problematic material, and agree on the disclosure.
Strong. This respects shared responsibility and allows correction before submission.
1/2 — Remove every AI-assisted sentence without discussion, even if it was permitted and verified.
This is cautious but bypasses group decision-making and may discard legitimate assistance unnecessarily.

Model reasoning: Tell the group, review the AI contributions together, correct or remove unverified work and agree on an accurate disclosure before submission.

Discussion prompt: Who has authority to decide whether the group accepts an AI-generated image?

3. Build the disclosure

Select the elements an accurate disclosure should include.

Required elements: The purpose: brainstorming, outline support, editing, image generation or another specific use., What the AI actually contributed., What the students verified, changed or created themselves., That the students reviewed and remain responsible for the final submission.

Model reasoning: State the actual tool/use, its contribution, the verification and human changes, and continuing responsibility. Disclosure must not be used to legitimise prohibited substitution.

Discussion prompt: What does a disclosure fail to repair if the group did not do the assessed work?

4. Choose the final statement

After the group verifies the outline and edits, independently redoes the calculations and checks the image, which disclosure is strongest?

1/2 — “AI was used.”
This discloses something but is too vague to show the extent of assistance or human work.
2/2 — “We used an AI tool to brainstorm topic angles, suggest an outline, edit selected sentences and generate an image. We checked the factual content and image, redid the calculations ourselves, revised the final work and remain responsible for the presentation.”
Strong. It is specific about contribution, checking, correction and responsibility.
0/2 — “No AI produced the final presentation because we edited the output.”
Editing does not erase the AI contribution and this wording conceals material assistance.

Model reasoning: Use a concise, specific statement describing permitted assistance, checks and human-created final work.

Discussion prompt: Should the statement name every prompt, or only the information needed for honest disclosure?
