A strong driving question is the engine of a sustained project-based learning (PBL) unit. It frames purposeful inquiry, motivates learners, and connects curriculum outcomes to a real-world product or performance. Use the guidance below to write driving questions that are open-ended, authentic, assessable and suited to Senior 1–4 cognitive levels.


What makes a driving question strong?

A productive driving question should meet these criteria:

  • Open-ended: invites investigation and multiple perspectives rather than a single correct answer.
  • Authentic and relevant: connected to real-world contexts, local communities or learners’ lives.
  • Aligned to CAPS outcomes: clearly tied to one or more specific Learning Outcomes and Assessment Standards.
  • Developmentally appropriate: matches cognitive demand for Senior 1–4 (recall → apply → analyse → evaluate → create).
  • Leads to evidence/product: implies a tangible artefact, performance or decision for assessment.
  • Manageable: feasible within the project timeframe and available resources.
  • Collaborative: invites teamwork and roles.
  • Clear and engaging language: understandable to learners; avoids jargon.
  • Equity-minded: accessible to diverse learners with options for scaffolding and differentiation.

Step-by-step: Craft a driving question

  1. Identify the CAPS outcome(s) and key content/skills you must address.
  2. Choose a real-world context that will engage learners (local problem, community need, enterprise, environmental issue).
  3. Select an appropriate cognitive verb (apply, explain, compare, design, evaluate, justify, create).
  4. Draft an open-ended question that leads to a product or public audience.
  5. Test the draft against the checklist (above). If it’s too narrow, broaden it; if too vague, tighten the context or expected product.
  6. Break the question into inquiry milestones and formative assessments.
  7. Write scaffolding sub-questions and rubrics that guide learners toward the final product.
  8. Review for safety, ethics and community permissions if the project involves public work or outdoor learning.

Quick checklist to validate a driving question

  • Does it require more than recall? (yes → proceed)
  • Can learners show learning through a product/performance? (yes)
  • Is it meaningful to the learners/context? (yes)
  • Is it feasible in time/resources? (yes)
  • Can you assess key CAPS skills within its scope? (yes)

If any answer is “no”, revise.


Examples by subject and Senior level

Each example gives: driving question → suggested final product → key milestones/sub-questions → CAPS alignment notes.

  • Natural Sciences (Senior 1)

    • Driving question: “How can we reduce litter and protect the pond at our school?”
    • Product: Community awareness campaign + improvement plan and poster/exhibition.
    • Milestones: water quality tests → identify litter sources → design interventions → present plan.
    • CAPS link: Scientific investigation, environmental systems.
  • Natural Sciences (Senior 4)

    • Driving question: “What local land-use practices are affecting groundwater quality, and which mitigation strategies are most effective?”
    • Product: Research report, model mitigation plan and community presentation.
    • Milestones: hypothesis formation → sampling and analysis → data interpretation → recommend interventions.
    • CAPS link: Scientific inquiry, data-handling, evaluation.
  • Social Sciences / Geography (Senior 2)

    • Driving question: “How can we make our neighbourhood safer for pedestrians and cyclists?”
    • Product: Map, campaign and presentation to local ward councillor or school governing body.
    • Milestones: survey routes → identify hazards → propose design changes → cost/benefit estimate.
    • CAPS link: Spatial skills, community-based inquiry.
  • History (Senior 3)

    • Driving question: “How did migration shape this town’s culture and economy between 1950 and 2000?”
    • Product: Multimedia exhibition and curator’s guide.
    • Milestones: source collection → oral histories → thematic analysis → exhibit curation.
    • CAPS link: Historical investigation, source evaluation.
  • English Home Language (Senior 1)

    • Driving question: “How can we tell the story of our school so others understand its culture?”
    • Product: Short documentary or anthology of narratives.
    • Milestones: interviewing → drafting → editing → publish/performance.
    • CAPS link: Listening, speaking, reading and writing integrated.
  • Mathematics (Senior 4)

    • Driving question: “What is the most cost-effective design for a small rainwater-harvesting system for our school?”
    • Product: Scaled design, calculations, cost analysis and prototype/model.
    • Milestones: measure catchment → calculate volumes → budget → design optimisation.
    • CAPS link: Measurement, data handling, problem solving.
  • Technology / Design (Senior 3)

    • Driving question: “How might we design a low-cost solar phone charger that works in our community?”
    • Product: Prototype, user manual and small pilot test results.
    • Milestones: research components → prototype build → user testing → iterate.
    • CAPS link: Technological processes, designing and making.
  • Life Orientation / Social Entrepreneurship (Senior 2)

    • Driving question: “How can we start a small school garden to improve food security and teach sustainability?”
    • Product: Business and care plan, planted garden and evaluation.
    • Milestones: soil tests → crop selection → labour plan → marketing/education.
    • CAPS link: Life skills, socio-economic rights and responsibilities.

How to convert closed questions into driving questions

  • Closed: “What causes erosion?” → Driving: “How can we reduce erosion on the sports field so it is usable all year?”
  • Closed: “What is climate change?” → Driving: “What local actions can our community take to reduce flood risk from changing rainfall patterns?”
    Technique: add context, a problem, or a stakeholder and require evaluation or design.

Scaffolding: sub-questions and milestones

A strong driving question must be broken into manageable inquiry chunks. Example scaffolding for “How can we reduce litter and protect the pond?”:

  • What types of litter are found in the pond?
  • Which areas contribute the most litter?
  • What are feasible interventions for our school?
  • How will we measure improvement?
    Assign milestones and pair each milestone with a formative assessment (data logs, drafts, peer critique).

Assessment mapping

  • Start with the driving question and identify summative evidence: product + presentation + reflection.
  • Map CAPS knowledge and skills to assessment criteria (rubrics): knowledge, inquiry process, collaboration, presentation, reflection.
  • Include formative checks at each milestone: observation notes, checklists, peer feedback, drafts.

Sample rubric dimensions: Understanding & application (30%), Inquiry & evidence (25%), Collaboration & roles (15%), Product quality (20%), Communication & reflection (10%).


Differentiation and inclusivity

  • Offer multiple ways to contribute (research, design, communication, practical work).
  • Adjust cognitive load: provide sentence stems, graphic organisers, or extension tasks.
  • Use mixed-ability groups and rotate roles so all learners access higher-order tasks.
  • Ensure language simplicity without dumbing down content.

Common pitfalls to avoid

  • Too broad: “How can we save the planet?” → narrow to a local, actionable focus.
  • Too narrow or factual: “What are the parts of a river?” → reframe with a problem.
  • No product or audience: learners must produce public work or defend recommendations.
  • Misalignment with CAPS: ensure the question targets assessable outcomes.

Use the checklist and examples above when designing your next PBL unit. Test each draft question with colleagues and a small group of learners; revise until it is engaging, curriculum-aligned and clearly leads to assessable learner work.
