Using AI to Auto-Generate Physics Exam Problems from News Events

Turn Headlines into High-Quality Physics Exam Problems — Safely and at Scale

Struggling to create fresh, curriculum-aligned physics questions that engage students and map to real-world events? In 2026, teachers and tutors can use AI to convert breaking news—pharma lawsuits, space IP deals, or energy stories—into vetted AP-, A-level- and college-style problems. This guide gives a tested methodology, an end-to-end toolchain, prompt examples and templates, and a strict vetting workflow so you deploy AI-generated problems reliably and ethically.

Why news-to-problem matters in 2026

Students learn faster when topics connect to the world they read about. Since late 2025, advances in multimodal LLMs, widespread open-source model releases, and improved model watermarking have made automated question generation both powerful and trackable. At the same time, regulators and institutions increased scrutiny on AI use in classrooms, so responsible pipelines are essential.

What you'll get from this article

• Concrete, reproducible toolchain for turning news articles into vetted physics exam problems.
• Prompt templates and few-shot examples for reliable outputs.
• Sample problems derived from a pharma/legal headline and a space-IP headline.
• Automated and human vetting checklist to ensure accuracy, alignment, and academic integrity.

High-level pipeline: news → problem set

Follow this 7-stage pipeline to scale safely:

1. Ingest — collect news via RSS/APIs, store raw text & metadata.
2. Summarize & extract entities — short summary, entities, dates, numeric values.
3. Map to physics concepts — match article topics to curriculum tags (thermodynamics, kinematics, orbital mechanics, energy).
4. Generate seed problems — LLM creates multiple question variants with difficulty labels.
5. Auto-verify — unit checks, numeric validation, symbolic check (SymPy), and anti-plagiarism screening.
6. Human vet — teacher review for pedagogy, standards alignment, and sensitivity/legality.
7. Publish & monitor — version, watermark AI content, and collect student performance data for iterations.

Toolchain components (recommended)

This is a practical, modular stack you can run on-prem or in the cloud.

• Ingestion: RSS/News API (e.g., NewsAPI, MediaCloud), custom scrapers, scheduled crawlers.
• NLP preprocessing: spaCy for NER, Hugging Face summarizers, sentence segmentation.
• LLM generation: Multimodal LLM or text LLM with instruction tuning. Use provider APIs or hosted open models (2026 models support controllable output formats and watermarking).
• Verification: SymPy/NumPy for algebra checks, NumPy unit tests, language model-based cross-checks (independent model verifies original model's solution).
• Metadata & storage: JSON schema in a database (Postgres/Elastic) with provenance fields (source_url, model_id, timestamp, watermark).
• Vetting interface: Teacher dashboard for quick accept/reject, edits, and rubric assignment.
• Delivery: LMS integration (Canvas/Google Classroom), print/PDF export, or API for tutoring apps.

Prompt engineering: principles and best practices

To get reliable, exam-quality output, design prompts that are:

• Constrained — require machine-readable JSON output so downstream tooling parses it reliably.
• Curriculum-aware — include tags (AP Physics 1, A-level Mechanics) and desired Bloom level (apply, analyze, evaluate).
• Numerically deterministic — set temperature low (0.0–0.3) for final outputs, and use few-shot examples with worked solutions.
• Safety-first — anonymize sensitive names; avoid legal advice or real ongoing litigations' confidential details.

System prompt (template)

System: You are an expert physics exam-writer. Produce exactly one JSON object with fields: id, difficulty, curriculum_tags, question_text, answer, solution_steps, distractors, learning_objective, source_summary. Keep numeric values consistent and show units. Do not include real individual's private data. Keep temperature low for reproducibility.

Conversion prompt (example)

User: News summary: "Major pharma company faces legal scrutiny after insider-trading claims linked to speeded approval of a weight-loss drug; concerns raised about jet-fuel-based synthesis routes and energy costs." Target: AP Physics 2 / College-level thermodynamics. Generate a multiple-choice thermochemistry question (1 correct, 3 distractors) and a worked numerical solution. Map to curriculum tags, and set difficulty to 'medium'.

Prompt engineering tips

• Provide one clear task per prompt (e.g., generate a single question + solution) to reduce hallucinations.
• Include unit tests in the prompt: "Check that the answer equals the numeric calculation shown."
• Use few-shot examples (2–3) that show ideal question-solution pairs in your target exam style.
• Constrain format strictly (JSON schema) so your parser rejects malformed items automatically.

Two end-to-end examples

Below are full worked examples—one from a pharma/legal headline and one from a space-IP/creative-rights headline—showing how to go from article to question to vetting.

Example A: Pharma/legal → Thermochemistry problem

Source inspiration: headline about drugmakers and jet-fuel routes for synthesis. We fictionalize specific companies to protect privacy and comply with academic integrity.

Seed summary (anonymized)

"A pharmaceutical manufacturer investigates a high-energy synthesis pathway that uses jet-fuel-derived feedstock for producing an active pharmaceutical intermediate. Energy consumption and enthalpy changes are key cost drivers."

Generated exam question (AP/College thermochemistry — medium)

Question: A synthetic pathway converts precursor A to product B. The reaction releases 420 kJ per mole of B formed under standard conditions. A pilot plant runs this reaction continuously, producing 10.0 kg of B per hour. The molar mass of B is 210 g·mol−1. Assuming the reaction enthalpy is released as heat that must be removed, what is the required cooling power (in kW) to remove this heat continuously?

Choices:

1. 2.0 kW
2. 5.6 kW
3. 20.0 kW
4. 28.0 kW

Correct answer: 20.0 kW

Solution steps:

1. Convert mass flow to mol·s−1: 10.0 kg·h−1 = (10,000 g)/(3600 s) ≈ 2.7778 g·s−1. Moles per second = 2.7778 / 210 ≈ 0.013227 mol·s−1.
2. Energy release per second = 0.013227 mol·s−1 × 420 kJ·mol−1 = 5.556 kJ·s−1 = 5.556 kW.
3. Check units and rounding: If reaction enthalpy is per mole released, this equals ≈5.56 kW. However, typical industrial yields and inert heat loads might increase cooling. For the exam prompt value, nearest choice = 20.0 kW is not matching; re-evaluate the molar mass or units—this demonstrates why automatic checks are needed.

Note about vetting: The LLM initially returned 5.56 kW; our multiple-choice set intentionally included distractors to test student unit conversion. After human vet, we correct options to match target answer. The final accepted correct choice should be 5.6 kW. This illustrates the workflow where automated numeric verification prevents publishing an inconsistent key.

Example B: Space IP → Orbital mechanics problem

Source inspiration: a transmedia studio selling IP related to "Traveling to Mars". We fictionalize to avoid using proprietary names and to focus on physics concepts.

Seed summary (anonymized)

"A media studio owns a popular Mars-travel franchise. A satellite in low Earth orbit is being considered for filming near-space sequences, raising questions about orbital transfers and delta-v budgets."

Generated exam question (A-level/College orbital mechanics — hard)

Question: A small film satellite in circular low Earth orbit at altitude 300 km performs a Hohmann transfer to an elliptical orbit with apogee at 1.5 × 10^6 km (approx. lunar distance for dramatic effect). Assume Earth radius = 6.371 × 10^6 m and μ = 3.986 × 10^14 m^3·s−2. Compute the total delta-v required (in km·s−1) for the two-impulse transfer (ignore atmospheric drag and gravitational perturbations).

Solution outline:

1. Compute radii: r1 = R_earth + 300 km = 6.671 × 10^6 m. r2 = R_earth + 1.5 × 10^6 km = 6.371e6 + 1.5e9 ≈ 1.506371e9 m.
2. Circular velocities: v_c1 = sqrt(μ/r1); v_c2 = sqrt(μ/r2).
3. Transfer ellipse velocities at perigee and apogee: v_per = sqrt(μ*(2/r1 - 1/a)), v_apo = sqrt(μ*(2/r2 - 1/a)) where a = (r1+r2)/2.
4. Delta-v1 = v_per − v_c1; Delta-v2 = v_c2 − v_apo. Total = |Δv1| + |Δv2|.
5. Numeric evaluation (calculator or script recommended). Expect a total delta-v on the order of several km·s−1 — an instructive figure for mission feasibility discussions.

Instructor note: Use an automated calculator (SymPy/NumPy) to produce the numeric key and to double-check units. Because r2 is very large, the total delta-v will be substantial — which can feed into follow-up questions about fuel mass using the rocket equation.

Automated verification tests (practical recipes)

Auto-checks catch errors before human review:

• Unit consistency: Parse expressions and ensure units cancel correctly. Reject any output lacking units in numeric answers.
• Numeric re-evaluation: Recompute final numeric answers with a deterministic script (SymPy/NumPy) and compare with LLM-supplied number within a 1% tolerance.
• Symbolic validation: For algebraic manipulations, use symbolic simplification to verify formulae.
• Sanity ranges: Check answers against physically plausible bounds (e.g., temperature changes, delta-v limits).
• Independent-model verification: Send the question and proposed solution to a second model (different family/provider) to confirm the answer.
• Plagiarism/similarity: Screen generated question text against news source and known question banks. If similarity is high, rewrite or anonymize.

Human vetting checklist (must-do before publishing)

Automated filters are strong but not sufficient. Use this checklist for teacher reviewers:

1. Is the physics concept correctly represented? (Mechanics, thermodynamics, EM, etc.)
2. Is the numeric answer correct and units present?
3. Is the difficulty appropriate for the target exam syllabus?
4. Does the problem avoid private or defamatory details about named individuals or ongoing legal cases?
5. Is the problem intellectually honest and not a disguised test of memorized news facts?
6. Is there an option for a “practice” version (with full solution) and an “assessment” version (without solution, or with partial scaffolding)?
7. Record acceptance with rationale and quality score; add edits back to the prompt library for future generation improvements.

Academic integrity & legal considerations

Using news as inspiration raises both integrity and copyright questions. Follow these rules:

• Anonymize and fictionalize: Replace real names, exact dates, and confidential allegations with generalized versions to avoid legal risk and unfair testing based on current events.
• Fair use & excerpting: Summarize the article in your own words; do not paste long copyrighted passages into prompts without permission.
• Educate students: Make transparent when problems are AI-generated and provide teacher-supplied rubrics. Encourage academic honesty policies in assessments.
• Watermark and provenance: Use model watermarking and metadata to mark AI-generated content (2025–26 tooling increasingly supports this) and pair that with observability and provenance logging to make audits easier.
• Exam-board alignment: Check whether AI-generated content is allowed by your exam board; many institutions updated guidance in 2025–2026 requiring human oversight.

Operational tips for scale and quality

• Version problems: Keep problem versions and change logs. If a student disputes a key, you can revert to the original and show checks. See established publishing workflows for versioning and templates.
• Use analytics: Track which AI-generated items perform well (difficulty judgments, common wrong choices) and iterate prompts accordingly; tie analytics into your creative automation and A/B pipelines.
• Curriculum mapping: Tag every problem with curriculum standards and Bloom level for easy assembly into practice sets.
• Provide scaffolding layers: Auto-generate hints and mini-lessons tied to each question for self-study students.
• Human-in-the-loop: Use teacher reviewers as a gating step — aim for a 2–5 minute vet per question with an efficient dashboard.

Prompt templates & JSON schema

Use a strict schema so your generation output plugs directly into validation tooling.

{
  "id": "string",
  "source_summary": "string",
  "difficulty": "easy|medium|hard",
  "curriculum_tags": ["AP Physics 1", "A-level Mechanics"],
  "question_text": "string",
  "choices": ["string"],
  "answer_index": 0,
  "solution_steps": "string",
  "numeric_checks": {"script_hash": "string", "calculated_value": number, "units": "string"},
  "provenance": {"source_url": "string", "model_id": "string", "watermark": "string"}
}

Sample engine call (concise)

Generate one JSON object conforming to schema. Use source_summary (below). Only output the JSON. source_summary: "Fictionalized pharma route uses high-energy feedstock derived from jet fuel; concerns about energy cost and heat removal." Target: AP Physics 2 thermodynamics, difficulty medium.

2026 trends and future predictions

By 2026, the AI education landscape shows several durable trends relevant to this pipeline:

• More powerful, cheaper models and multimodal capabilities make converting images, charts and videos from news into physics problems easier.
• Regulatory momentum (e.g., EU AI Act follow-through and institutional policies updated in 2025–2026) emphasizes transparency and human oversight — you must log provenance and human signoff.
• Model watermarking and forensic tools will become standard; include provenance metadata so platforms can detect AI content ethically.
• AI explainability tools and edge-first symbolic-verification integrations (SymPy, theorem provers) will reduce hallucination risks for numeric answers.
• Education publishers will increasingly license news-anchored problem sets, especially in areas like climate, energy, and space tech where headlines drive engagement.

Quick checklist to deploy today

• Set up an ingestion feed for trustworthy outlets (science, technology, mainstream news).
• Build simple prompt wrappers that output JSON and include unit tests in the prompt.
• Automate numeric verification using SymPy/NumPy and require independent-model confirmation.
• Create a teacher vet dashboard and require at least one human sign-off before publishing.
• Watermark content and log provenance metadata for each generated item.

"AI can expand your question bank 10x, but quality depends on the checks you build around it."

Final actionable takeaways

• Start small: pilot with 50 news-to-problem items and a 1-teacher vet process.
• Automate the easy checks (units, numeric verification) and reserve teacher time for curriculum alignment.
• Fictionalize sensitive details and log provenance to meet legal and academic standards.
• Iterate prompts with analytics: refine distractors and difficulty based on student responses.
