Problem Solving

How to approach problems you have not seen before — understanding what the problem actually is, generating possible solutions, choosing the most promising, and learning from what happens. Problem solving is not about knowing the answer. It is about knowing how to find it.

Key Ideas at This Level
1 A problem is something that needs a solution — and almost all problems have one.
2 The first solution you think of is not always the best one.
3 We can break a big problem into smaller parts.
4 It is good to try more than one way when something is not working.
5 Asking for help is part of solving problems, not a sign of failure.
Teacher Background

Problem solving at Early Years level is about building the foundational disposition towards problems — the belief that problems can be solved, the habit of trying more than once, and the willingness to ask for help and try different approaches. Young children encounter genuine problems every day — how to share resources fairly, how to build something that keeps falling down, how to communicate a need that is not being understood, how to manage a conflict with a friend. These are real problems with real solutions and they are the ideal material for problem-solving education. The most important teaching move at this level is to resist solving problems for children. When a child encounters a problem — a block construction that keeps falling, a conflict over materials, a misunderstanding with a friend — the teacher's first response should be: what have you tried? What could you try next? only solving for the child when genuine help is needed removes the learning opportunity. The second most important move is to celebrate persistence: the child who tries five different approaches before finding one that works is learning more about problem solving than the child who finds the answer immediately. In low-resource settings, problems of a practical and material nature are daily realities — finding water, making things work with limited materials, resolving community disputes, managing shared resources. These are excellent material for problem-solving education and should be honoured as such rather than substituted with imported problems from wealthy-world contexts.

Skill-Building Activities
Activity 1 — What is the problem? Understanding before solving
PurposeChildren learn that clearly understanding a problem is the essential first step — that jumping to solutions before understanding the problem is one of the most common problem-solving mistakes.
How to run itTell a short story with a problem that has been misunderstood. Example: a family was cold at night. They decided they needed more blankets and spent a lot of time looking for them. But the real problem was that there was a hole in the wall letting cold air in. Ask: did they solve the problem? What went wrong? What should they have done first? Introduce the idea: before you solve a problem, you need to understand it properly. Ask: what is really the problem here? is the most important question. Now give children three simple problems and for each one ask them to describe the problem in their own words before suggesting any solution. Problem 1: your friend is crying. Problem 2: the plants in the school garden are dying. Problem 3: two children both want to use the same pencil. For each one, ask: what might be causing this problem? Are there different possible causes? Does the solution depend on the cause? A crying friend might be sad about something at home, or hurt, or missing someone — each requires a different response. Celebrate children who ask questions to understand the problem before suggesting solutions.
💡 Low-resource tipNo materials needed. Use problems from the actual daily life of the classroom and community — they are more engaging than invented problems and produce more genuine thinking. The teacher modelling curiosity about the real cause of a problem — before jumping to solutions — is itself the most powerful lesson.
Activity 2 — Try another way: persistence and flexibility
PurposeChildren build the habit of trying multiple approaches when the first one does not work — the most important practical problem-solving behaviour.
How to run itSet children a simple physical problem with no single obvious solution — building the tallest possible tower from available materials, getting a small object from one side of a line to another without crossing it, tying two pieces of string together using only one hand. When the first approach fails (as it often will), ask: what happened? Why did that not work? What could you try differently? Model this yourself: try something, fail, think aloud about what went wrong, try something different. The verbal think-aloud is the most important part — children need to see the thinking process, not only the outcome. After the activity, discuss: how many different things did you try? Which try taught you the most? How did it feel when the first approach did not work? Did it feel different by the fifth try? Introduce the idea: every time you try something that does not work, you learn something useful. The question is not just did it work? but what did I learn from it? Connect to something from the children's cultural experience — a proverb about persistence, a story about someone who kept trying.
💡 Low-resource tipUse whatever materials are immediately available — sticks, stones, cloth, paper, hands. The specific materials matter much less than the experience of genuine failure and persistence. Problems that are genuinely difficult for children at this age work better than ones they solve immediately.
Activity 3 — Working together on a hard problem
PurposeChildren experience that bringing different ideas together — collaboration — produces better solutions to hard problems than working alone.
How to run itGive children individually a genuinely hard problem — something they are unlikely to solve alone. Example: how could the class make the outside space more comfortable to sit in during the hottest part of the day, using only things available for free? Give each child two minutes to think alone and note (draw or remember) one or two ideas. Then bring children together in groups of four to share ideas. Ask each group to combine the best elements of their individual ideas into one shared plan. Compare group plans with individual ideas: are the group plans better? What did each person contribute that the others had not thought of? Introduce the idea: some problems are too big or too complex for one person alone. When people with different experiences and ideas work together, they usually produce better solutions. Ask: what made this group work well (or not well)? What would have helped the group solve the problem even better?
💡 Low-resource tipNo materials needed. The problem should be genuinely local and relevant — the outside space, the water supply, the classroom, the garden. Children engage more deeply with problems that actually affect their lives. The teacher should not suggest solutions — the goal is for children to generate and combine their own ideas.
Reflection Questions
  • Q1What is the hardest problem you have ever solved? How did you do it?
  • Q2When something is not working, do you usually try a different way or do you give up? Why?
  • Q3Is it better to solve a problem by yourself or to ask for help? Does it depend on the problem?
  • Q4Have you ever solved a problem in a way that surprised you? What happened?
  • Q5Can you think of a problem in your school or community that nobody has solved yet? What might be stopping people from solving it?
Practice Tasks
Drawing task
Draw a problem you solved. Show what the problem was, what you tried, and what worked in the end. Write or say: the problem was __________, I tried __________, and what worked was __________.
Skills: Building narrative understanding of the problem-solving process — normalising multiple attempts and celebrating persistence
Model Answer

Three connected drawings showing the problem, an attempt (or attempts), and the solution. The completion shows that the student tried at least one approach before finding one that worked — not that the first thing worked immediately. Celebrate drawings that show more than one attempt.

Marking Notes

Ask: what did you learn from the things that did not work? This question is more important than the solution itself — it builds the habit of treating failures as information.

Problem identification task
Find one problem in your classroom, school, or home. Write or say: the problem is __________, it affects __________, and one thing I could try is __________.
Skills: Building the habit of noticing problems and thinking about their impact and possible solutions — the foundation of civic and practical problem-solving
Model Answer

The problem is that the school gate makes a very loud noise when it opens and it wakes up the babies in the house next door. It affects the family who live there and makes their day harder. One thing I could try is asking if someone could put oil on the hinges to make it open quietly.

Marking Notes

Celebrate any genuine problem and any genuine proposed solution, however small or simple. The habit of noticing problems and thinking constructively about them is the goal, not the sophistication of the solution.

Common Mistakes
Common misconception

If you cannot solve a problem quickly, it means you are not clever enough to solve it.

What to teach instead

The speed at which someone solves a problem often reflects familiarity with that type of problem, not raw intelligence. Novel problems — ones you have not seen before — take time for everyone. The people best at problem solving are not those who find answers fastest but those who persist longest and try the most different approaches. Research on expert problem solvers shows they spend more time than novices understanding the problem before attempting a solution — which is slower but more effective.

Common misconception

Asking for help is giving up on solving the problem yourself.

What to teach instead

Knowing when to ask for help is itself a problem-solving skill — and an important one. Experienced problem solvers know when a problem is beyond their current tools and when getting input from others will produce a better solution than continuing alone. What matters is how you ask: asking someone to solve the problem for you is different from asking for a hint, a resource, or a perspective that helps you solve it yourself. The ability to use other people and other resources effectively is part of being a good problem solver.

Common misconception

Problems have one correct solution.

What to teach instead

Many problems — especially real-world problems — have multiple workable solutions with different trade-offs. The question is not only does this solution work? but which solution works best given the specific constraints, values, and resources available? Often different solutions serve different people's needs differently. The habit of generating multiple possible solutions before choosing one — rather than stopping at the first workable answer — produces better outcomes in almost every domain.

Key Ideas at This Level
1 The problem-solving process — a structured approach that works across domains
2 Defining the problem — why the right question is more important than the right answer
3 Generating solutions — techniques for producing more and better options
4 Evaluating solutions — how to choose between competing options
5 Implementing and reviewing — acting on a solution and learning from what happens
6 Wicked problems — why some problems resist straightforward solutions
Teacher Background

Problem solving at primary level introduces students to a structured process for approaching problems — moving from an intuitive, trial-and-error approach towards a more deliberate and transferable one. The structured problem-solving process has several well-established versions; a practical synthesis for classroom use is: understand the problem (what exactly is the problem? who is affected? what are the constraints?), generate options (produce multiple possible solutions without evaluating them), evaluate options (assess each against the constraints and desired outcomes), implement (act on the chosen solution), and review (did it work? what did you learn?). This process is not a formula to be followed mechanically — it is a set of habits that become more automatic with practice. The most important and most neglected step is the first: understanding the problem properly. Research on problem solving consistently shows that the most common source of poor solutions is not a failure of intelligence but a failure to correctly identify what the problem actually is. People jump to solutions before they understand the problem they are solving — and the solutions they generate are therefore solutions to the wrong problem.

Wicked problems

The distinction between tame problems (well-defined, with a clear correct solution) and wicked problems (ill-defined, with multiple stakeholders, no clear correct solution, and where any solution changes the problem) is important for realistic civic education. Most real-world problems — poverty, conflict, environmental degradation, public health — are wicked. Understanding this helps students engage more maturely with why persistent problems persist and why simple solutions usually fail.

Problem solving across domains

The structured process above is the same whether the problem is mathematical, social, practical, or creative. Helping students recognise this — that the same thinking process applies across different types of problem — is one of the most valuable transferable lessons in the curriculum.

Key Vocabulary
Problem
A situation in which there is a gap between where you are and where you want to be — and the path from one to the other is not immediately obvious.
Constraint
A limit that any solution must work within — available time, resources, skills, rules, or relationships. Understanding constraints is essential to generating realistic solutions.
Root cause
The underlying reason a problem exists — as opposed to its visible symptoms. Solving the root cause eliminates the problem; solving only the symptom allows it to return.
Criteria
The standards a solution must meet to be acceptable — the conditions for success. Defining criteria before evaluating solutions makes the evaluation much more objective and useful.
Trade-off
A situation in which gaining one thing requires giving up another. Most real-world solutions involve trade-offs — the question is which trade-off is most acceptable given the specific situation.
Prototype
A quick, rough, low-cost version of a proposed solution — built to test whether the idea works before committing fully to it.
Wicked problem
A problem that is ill-defined, has multiple stakeholders with different interests, has no single correct solution, and where any solution changes the problem. Most important real-world problems are wicked.
Five Whys
A technique for finding root causes by asking why five times in succession — each answer becomes the subject of the next why. Developed at Toyota and widely used in problem-solving and quality improvement.
Skill-Building Activities
Activity 1 — The Five Whys: finding the root cause
PurposeStudents practise the most important single problem-solving technique — asking why repeatedly until the root cause is found — and discover that surface solutions often fail because they address symptoms rather than causes.
How to run itIntroduce the Five Whys technique with a simple example. Problem: the students are often late to school. Why? Because they wake up late. Why do they wake up late? Because they go to sleep late. Why do they go to sleep late? Because they are doing household tasks in the evening. Why are they doing household tasks in the evening? Because there is not enough time during the day. Why is there not enough time during the day? Because the school day ends at a time that conflicts with the water collection schedule. The root cause — a scheduling conflict — is very different from the presenting problem (lateness) and requires a very different solution. Practice the Five Whys in groups with three locally relevant problems: crops are not growing well, students are not completing homework, the classroom is often too noisy to concentrate. For each problem, ask why five times, writing each answer. Compare root causes across groups — different groups often find different root causes, which itself reveals something about the complexity of real problems. Debrief: what would have happened if you had solved the presenting problem rather than the root cause? Who gets to define what the root cause is, and does it matter?
💡 Low-resource tipWorks entirely through discussion. Any surface is fine for writing the why chain — a piece of paper, the board, or simply spoken aloud. Use genuinely local problems — the more real, the more powerful. Teachers who let students apply this to problems in their actual lives produce the most engaged thinking.
Activity 2 — Generating and evaluating: the solution matrix
PurposeStudents practise separating idea generation from idea evaluation — producing more and better solutions by delaying judgment — and then evaluating options systematically against agreed criteria.
How to run itGive groups a specific, realistic local problem. Phase 1 — generation (five minutes, no evaluation): generate as many possible solutions as possible. All ideas accepted, no criticism, wild ideas welcome. Count the ideas generated. Phase 2 — criteria definition: before evaluating, agree on what a good solution must achieve. It should be: practical with available resources; acceptable to most people affected; solve the root cause rather than just the symptom; sustainable — able to continue without constant outside input. Phase 3 — evaluation: assess each idea generated against the criteria. Use a simple grid — idea in one column, each criterion in the other columns, a simple yes/partly/no in each cell. Which ideas score well across all criteria? Are there any that score perfectly? Are there trade-offs? Phase 4 — refinement: can you combine the best elements of two or three ideas into one stronger solution? Debrief: what was different about this process compared to how you usually approach problems? Was it harder or easier? Did you generate ideas you would not have thought of if you had been evaluating as you went?
💡 Low-resource tipThe matrix can be drawn on any available surface. Works entirely without printed materials. The process can also be run verbally in smaller groups. The separation of generation and evaluation phases is the key learning — even if the matrix is not drawn formally.
Activity 3 — Wicked problems: when there is no right answer
PurposeStudents encounter the concept of wicked problems — realising that not all problems have clear solutions and that understanding why helps them engage more maturely with persistent real-world challenges.
How to run itIntroduce the distinction between tame and wicked problems. A tame problem has a clear definition, a known solution method, and a solution that can be checked as correct or incorrect — like a maths problem or a puzzle. A wicked problem has multiple possible definitions (depending on who you ask), no agreed correct solution, multiple stakeholders with conflicting interests, and where any solution changes the problem and creates new ones. Give students a clearly tame problem and a clearly wicked problem and ask them to discuss what is different about each. Tame: how do we get the school garden to produce more vegetables this season? Wicked: how do we fairly share the water from the community well when there is not enough for everyone? For the wicked problem, ask: who has a stake in this problem? What does each stakeholder want? Are any of those wants in genuine conflict? Is there a solution that works for everyone? What happens if you solve it in the way that works best for the majority? What happens to the minority? Now ask: can you think of a wicked problem that your community or country has been trying to solve for a long time? Why has it been so hard? What would a good enough — if not perfect — approach look like?
💡 Low-resource tipWorks entirely through discussion. The tame and wicked examples should be genuinely local. Wicked problems from students' own communities — land disputes, water access, school funding, community conflicts — are far more engaging than imported examples and connect problem-solving directly to civic education.
Reflection Questions
  • Q1Think of a problem you solved recently. Did you use a structured process or did you react immediately? Would a structured process have helped?
  • Q2Have you ever solved the wrong problem — found a solution that addressed the symptom but not the real cause? What happened?
  • Q3What is the hardest problem in your community right now? Why has it not been solved? Is it a tame or a wicked problem?
  • Q4Is there ever a situation where the first solution you think of is definitely the best one? Or should you always generate alternatives first?
  • Q5When several people need to solve a problem together but have different interests, who should decide on the solution? What process makes this fair?
  • Q6Can you think of a solution to a problem that made the problem worse? What went wrong?
Practice Tasks
Task 1 — Apply the problem-solving process
Choose a real problem in your school or community. Apply the full problem-solving process: (a) describe the problem clearly and identify its root cause using the Five Whys; (b) list at least six possible solutions; (c) define three criteria a good solution must meet; (d) evaluate your best three solutions against the criteria; (e) recommend one solution and explain your choice. Write 4 to 6 sentences plus your lists.
Skills: Applying the full structured problem-solving process to a real local problem
Model Answer

Problem: students do not have shade to sit in during the lunch break and spend the hottest part of the day in direct sun. Five Whys root cause: the school was built without shade structures and there is no budget to add them — the root cause is a design and resource decision made when the school was built. Six possible solutions: plant fast-growing trees along the south side; build simple shade structures from locally available poles and thatch; arrange for a large cloth to be stretched between posts; use the corridor of the main building for sitting during the hottest thirty minutes; shift the lunch break to the cooler part of the day; ask families to donate materials for a simple shade structure. Three criteria: must be achievable with no budget; must provide shade within this school year; must not require maintenance that the school cannot provide. Evaluating top three: (1) rearranging lunch break — meets all three criteria immediately; (2) plant trees — meets first and third criteria but not the second, as trees take years to grow; (3) cloth shade — meets all three criteria if cloth can be donated. Recommendation: rearrange the lunch break immediately as it costs nothing and can be done tomorrow, and simultaneously ask the community for cloth donations to build a temporary shade structure this term.

Marking Notes

Award marks for: a specific and real problem; genuine root cause identification using the Five Whys rather than just restating the problem; a list that contains creative as well as obvious options; criteria that are specific and genuinely useful for differentiating between options; evaluation that produces a clear recommendation rather than saying all options are equally good; and a recommendation with a clear rationale. Strong answers will recognise when the best solution is a combination of approaches rather than a single one.

Task 2 — Analyse a failed solution
Choose a real example — from your community, your country, or the world — of a solution to a problem that did not work or made things worse. Write: (a) what the problem was; (b) what solution was tried; (c) why it failed — using the concepts from this unit; (d) what a better approach might have looked like. Write 4 to 6 sentences.
Skills: Applying problem-solving concepts to a real failure — building analytical rather than only constructive problem-solving skills
Model Answer

In my community, the water point near the market kept running out of water before everyone had collected what they needed. The solution tried was to install a lock on the pump and give only certain families a key, so that use could be controlled. This made things worse because the families without keys had even less access than before, and there were arguments about who deserved a key, which created new conflicts. The root cause — that the water supply was simply not sufficient for the number of people using it — was not addressed at all; the solution only managed the scarcity rather than reducing it. A better approach would have used the Five Whys to find the root cause first (why is there not enough water? because the source is insufficient; why is the source insufficient? because population has grown but the infrastructure has not) and then sought solutions that addressed supply rather than only restricting access.

Marking Notes

Award marks for: a specific and genuine example; an honest and specific analysis of why the solution failed — not just it did not work but specifically which step in the problem-solving process was missing or done poorly; and a proposed alternative that genuinely addresses the root cause rather than the symptom. Strong answers will identify that the failed solution addressed the symptom (too many people trying to use too little water) rather than the root cause (too little water), and will propose an approach that includes more stakeholders in defining and solving the problem.

Common Mistakes
Common misconception

A smart person will be able to see the right solution to a problem immediately.

What to teach instead

Expert problem solvers consistently spend more time than novices in the problem understanding phase — before attempting any solution. Research on chess masters, scientists, engineers, and medical diagnosticians all show the same pattern: expertise produces slower, more thorough problem analysis, not faster intuitive leaps. The intuition that experienced problem solvers appear to exercise is actually pattern recognition built from thousands of previous structured attempts — it looks like immediate insight but is the product of accumulated deliberate practice.

Common misconception

Problem solving is a talent — some people are naturally better at it than others.

What to teach instead

Problem-solving ability is highly trainable. Research on problem-solving education consistently shows that explicit instruction in problem-solving processes — understanding the problem, generating multiple options, evaluating systematically, reviewing outcomes — produces significant improvements in performance across all ability levels. The structured process in this unit is not a description of how good problem solvers happen to think naturally — it is a learned and practised approach that makes almost anyone a better problem solver.

Common misconception

Once you have found a solution that works, the problem-solving process is complete.

What to teach instead

Review — checking whether the solution actually worked and what you learned from it — is the most neglected and one of the most valuable stages of the problem-solving process. Solutions that appear to work often have unintended consequences or only partially address the problem. Regular review produces continuous improvement and prevents solutions from calcifying into problems. The review stage also builds the learning from experience that makes future problem solving faster and more effective.

Common misconception

All problems can eventually be solved if you are persistent and clever enough.

What to teach instead

Wicked problems — complex, multi-stakeholder, value-laden social problems — do not have final solutions. They have better and worse management approaches that trade off different values and interests. Recognising that a problem is wicked is not giving up — it is adjusting your approach realistically. For wicked problems, the most important skills are stakeholder inclusion, ongoing monitoring, willingness to adjust, and humility about the limits of any single approach. Treating a wicked problem as if it were tame — by applying a single solution with confidence that it is correct — is one of the most common and most damaging mistakes in governance, development, and community management.

Key Ideas at This Level
1 Systems thinking and problem solving — understanding problems in context
2 Cognitive biases in problem solving — how our minds mislead us
3 Design thinking — a human-centred approach to problem solving
4 Problems of values and problems of knowledge — different types of problem require different approaches
5 Collective problem solving — how groups solve problems better and worse than individuals
6 Problem solving in high-stakes situations — when decisions must be made quickly and under pressure
Teacher Background

Secondary problem solving engages students with the deeper cognitive, social, and ethical dimensions of problem solving — particularly the ways in which human cognition systematically misleads us, the difference between technical and values-based problems, and the conditions under which collective problem solving is more or less effective than individual.

Cognitive biases

Research in cognitive psychology and behavioural economics has identified a large number of systematic patterns in human judgment that regularly produce poor problem-solving decisions. The most important for students include: confirmation bias (seeking information that confirms existing beliefs and discounting information that challenges them), anchoring (over-weighting the first piece of information received), availability heuristic (judging the probability of events by how easily examples come to mind rather than by actual frequency), sunk cost fallacy (continuing an unproductive course of action because of investment already made), and functional fixedness (being unable to see uses for objects beyond their usual function). These are not failures of intelligence — they are built-in features of human cognition that affect experts as much as novices. Understanding them is the first step to compensating for them.

Design thinking

Developed at Stanford's d.school and widely applied in business, social sector, and education contexts, design thinking is a human-centred problem-solving approach with five stages: empathise (understand the human experience behind the problem), define (frame the problem from the user's perspective), ideate (generate many possible solutions), prototype (build quick, cheap versions to test), and test (gather feedback and iterate). Its emphasis on genuine empathy with those affected by the problem — rather than assuming you know what they need — distinguishes it from more technical problem-solving approaches and makes it particularly appropriate for social and community problems.

Technical versus values-based problems

This distinction is one of the most important for civic and political education. Technical problems (how do we build a bridge that will not fall down?) have solutions that can be assessed objectively against physical criteria. Values-based problems (how should we distribute limited healthcare resources between different groups?) require choices between competing values that cannot be resolved by technical analysis alone. Much of the confusion and frustration in public debate arises from treating values-based problems as if they were technical ones — assuming that more evidence will resolve a dispute that is actually about whose values should prevail.

Key Vocabulary
Confirmation bias
The tendency to seek, interpret, and remember information that confirms what you already believe — and to discount or avoid information that challenges it. One of the most powerful and most dangerous cognitive biases in problem solving.
Sunk cost fallacy
The tendency to continue with an unproductive course of action because of investment (time, money, effort) already made — rather than making a fresh decision based on future costs and benefits. Rational decision-making requires ignoring sunk costs.
Anchoring
The tendency to over-rely on the first piece of information received when making a decision — even when that information is arbitrary or irrelevant. Anchoring is one of the most well-documented and practically significant cognitive biases.
Design thinking
A human-centred problem-solving approach with five stages: empathise, define, ideate, prototype, and test. Design thinking starts with a deep understanding of the human experience behind the problem before generating solutions.
Functional fixedness
The inability to see uses for an object or resource beyond its conventional purpose. Functional fixedness is one of the most common barriers to creative problem solving — particularly in low-resource contexts where conventional solutions are unavailable.
Technical problem
A problem that can be solved through knowledge and analysis — where there is a correct solution that can be tested objectively against agreed criteria.
Values-based problem
A problem that requires choices between competing values — where technical analysis alone cannot determine the correct solution because different people with different values will reach different conclusions from the same evidence.
Groupthink
The tendency of groups to converge on consensus and suppress dissent — producing worse collective decisions than individuals would have made alone. Groupthink is most likely in cohesive groups with a strong leader who signals their preferred outcome.
Devil's advocate
Someone who deliberately argues against the prevailing view in a group — not because they necessarily believe the counter-argument but to test its strength and prevent groupthink. Assigning a devil's advocate role is one of the most effective techniques for improving group decision quality.
Satisficing
Choosing a solution that is good enough rather than optimal — a term coined by Herbert Simon. In situations of uncertainty and complexity, satisficing is often more rational than attempting to find the perfect solution.
Skill-Building Activities
Activity 1 — Cognitive biases in action: how your brain misleads you
PurposeStudents experience specific cognitive biases directly — building the self-awareness needed to compensate for them in real problem-solving situations.
How to run itRun three short demonstrations, each revealing a different bias. Demonstration 1 — Anchoring: ask half the class to estimate the population of a large country before seeing the number 400 million. Ask the other half to estimate after seeing the number 100 million. Compare the estimates — the group that saw the higher anchor will give systematically higher estimates. Demonstration 2 — Confirmation bias: give students a four-card task. Four cards show A, K, 4, 7. The rule is: if a card has a vowel on one side, it must have an even number on the other. Which cards must you turn over to test the rule? Most people turn over A and 4 (they seek confirming evidence) when the correct answer is A and 7 (you must also look for disconfirming evidence). Demonstration 3 — Sunk cost: present a scenario: you bought a ticket to a concert for the equivalent of a week's food budget. On the day, you feel unwell and going will make you feel worse. Should you go? Most people say yes (sunk cost) when the rational answer is no — the ticket money is gone regardless. After each demonstration, discuss: how could this bias affect problem solving in your community or professional life? What techniques could compensate for it? Introduce the general lesson: the solution to cognitive bias is not to try harder to be rational — it is to build in deliberate structures (diverse groups, devil's advocate roles, pre-mortems) that compensate for known limitations.
💡 Low-resource tipWorks entirely through discussion and the thought experiments described. No materials needed. The four-card demonstration works with physical cards written on paper. The anchoring demonstration works with any large number the teacher knows in advance.
Activity 2 — Design thinking: starting with the human
PurposeStudents apply the design thinking framework to a real local problem — developing the habit of deep empathy and user-centred problem definition before generating solutions.
How to run itIntroduce design thinking's first two stages — empathise and define — as the most neglected and most important parts of problem solving. Empathise: before you can solve a problem well, you must deeply understand the experience of the people who have it. This means listening more than analysing — finding out not just what the problem is but what it feels like, what workarounds people have already developed, and what a good solution would mean to them. Give students a specific local problem and ask them to spend fifteen minutes in pairs conducting a brief empathy interview — one student plays the person affected, one plays the problem-solver asking genuinely curious questions. Not what is the problem? but walk me through your day and tell me where this becomes difficult. What have you already tried? What would change for you if this was solved? Define: after the empathy phase, frame the problem from the perspective of the person affected. Not we need a better water system but a person who collects water needs a way to reduce the time this takes each day so they can spend that time working or with their children, because the current system leaves them exhausted and with no time for other priorities. This reframing often reveals solutions that would not have emerged from a technical problem definition. Generate solutions only after completing both stages. Debrief: how did the problem definition change after the empathy phase? Were the solutions different from what you would have generated without it?
💡 Low-resource tipNo materials needed. The empathy interview works in any space and language. Use a genuinely local problem — water, transport, healthcare access, food, education — that directly affects students or their families. The closer to their lived experience, the more genuine the empathy.
Activity 3 — Technical or values-based? Recognising the type of problem you have
PurposeStudents learn to distinguish between problems that require better knowledge and analysis and problems that require choices between competing values — and understand why the distinction matters for how the problem should be approached.
How to run itPresent four problems and ask students to classify each as primarily technical, primarily values-based, or both. Problem 1: how do we design a water purification system for a community without mains water? (Primarily technical — there are engineering solutions that can be objectively assessed.) Problem 2: should scarce clean water be distributed equally to all households or allocated based on need? (Primarily values-based — equality and need are both legitimate values in genuine tension.) Problem 3: what is the most effective teaching method for children who are struggling to read? (Mixed — partly technical, with evidence about effective methods, and partly values-based, about what education is for and whose definition of struggling counts.) Problem 4: should a community relocate to avoid flooding risk, or stay and adapt? (Mixed — partly technical risk assessment, partly values-based choices about community, identity, and acceptable risk.) Discuss each: what information would help? Would more information resolve the disagreement or would it remain even with perfect information? What would need to happen for the values-based problems to be resolved fairly? Who should make these decisions? What process would be legitimate? Connect to the citizenship skills topic: the distinction between technical and values-based problems is at the heart of democratic governance.
💡 Low-resource tipWorks entirely through discussion. Use problems that are genuinely relevant to students' context. The classification is less important than the reasoning — students who can articulate why a problem requires both technical analysis and values choices understand something fundamental about governance and civic life.
Reflection Questions
  • Q1Think of a decision you have made that turned out to be a mistake. Looking back, can you identify a cognitive bias that contributed to the poor decision?
  • Q2Is there a persistent problem in your community that well-intentioned people keep trying to solve without success? Is it a wicked problem? What would a genuinely effective approach look like?
  • Q3Design thinking starts with empathy — deeply understanding the experience of people affected by the problem. Why is this so often skipped, and what are the consequences when it is?
  • Q4When a group makes a worse decision than an individual would have made alone, what went wrong? How can groups be organised to make better decisions?
  • Q5What is a problem in your country that appears to be technical but is actually primarily about values? What does recognising this change about how it should be approached?
  • Q6Herbert Simon argued that in complex real-world situations, satisficing — choosing a good enough solution — is more rational than seeking the perfect solution. Do you agree? Under what conditions?
Practice Tasks
Task 1 — Diagnose a persistent problem
Choose a persistent problem in your community or country that has resisted multiple attempted solutions. Write: (a) what the problem is and how long it has persisted; (b) what solutions have been tried and why they have not fully worked; (c) whether it is primarily a technical problem, a values-based problem, or a wicked problem — with your reasoning; (d) which cognitive biases may have contributed to the failed solutions; (e) what a more effective approach would look like. Write 300 to 400 words.
Skills: Applying problem-solving concepts to a real persistent problem — developing the analytical understanding of why problems persist
Task 2 — Essay: problem solving and wisdom
Choose ONE of the following questions and write a 400 to 600 word essay. (a) Cognitive biases are built into human cognition and cannot be fully overcome — so the best approach to important decisions is to build structural compensations rather than trying to think more carefully. Do you agree? (b) Most of the most important problems facing humanity are wicked problems — so the skills needed to address them are not technical but ethical, political, and interpersonal. Do you agree? (c) Design thinking's emphasis on empathy and human-centred problem definition is valuable — but it risks treating structural problems as if they can be solved through better design. What is missing from design thinking as an approach to social problems?

Common Mistakes
Common misconception

Experts are immune to cognitive biases because of their training and experience.

What to teach instead

Research consistently shows that expertise does not eliminate cognitive biases and sometimes amplifies them. Experienced doctors show confirmation bias when diagnosing — their pattern recognition, while usually valuable, can make them close too quickly on a diagnosis that fits their initial impression. Experienced investors are as prone to sunk cost reasoning as novices. The most effective compensation for cognitive bias is structural — building in processes that force consideration of alternative hypotheses, dissenting views, and base rate information — not simply trying to think more carefully.

Common misconception

Groups always make better decisions than individuals because more perspectives are included.

What to teach instead

Groups can make better decisions than individuals when they are diverse, when all members contribute freely, and when the group process is designed to prevent premature convergence. But groups can also make dramatically worse decisions than individuals — through groupthink (suppression of dissent), social loafing (reduced individual effort in group settings), cascade effects (later members deferring to earlier ones), and polarisation (groups moving to more extreme positions than any individual held). The conditions for good group decision-making must be actively created rather than assumed to arise naturally.

Common misconception

Better information always leads to better problem solving.

What to teach instead

More information does not automatically produce better decisions — it can produce worse ones if it exceeds cognitive processing capacity, if it is selected to confirm existing beliefs, or if the additional information is irrelevant to the actual decision. Research by Barry Schwartz and others shows that expanding the number of options available often produces worse decisions and less satisfaction than limiting choices. The relationship between information and decision quality is non-linear and depends heavily on how information is presented, filtered, and integrated into the decision process.

Common misconception

Problem solving is a purely cognitive skill — emotions are obstacles to clear thinking.

What to teach instead

Research by Antonio Damasio and others shows that emotion is not an obstacle to rational decision-making but a necessary component of it. Patients with damage to emotion-processing brain regions cannot make effective decisions even when their logical reasoning is intact — they become paralysed by the inability to assign relative value to options. Emotions provide the motivational and evaluative signal that makes choice possible. Good problem solving requires emotional awareness — particularly the emotions of the people affected by the problem — alongside analytical rigor.

Further Practice & Resources

Key texts and resources: Daniel Kahneman's Thinking, Fast and Slow (2011, Farrar Straus and Giroux) is the most comprehensive and accessible account of cognitive biases and their effects on judgment and decision-making — written by one of the founders of behavioural economics and suitable for strong secondary students. Richard Thaler and Cass Sunstein's Nudge (2008, Yale) applies behavioural insights to policy design — useful for understanding structural compensations for bias. For design thinking: IDEO's Design Kit (designkit.org) provides free, practical resources on human-centred design specifically for social impact contexts — directly applicable to low-resource settings. Tim Brown's Change by Design (2009, Harper Business) is the foundational readable account of design thinking. For wicked problems: Horst Rittel and Melvin Webber's original 1973 paper Dilemmas in a General Theory of Planning (freely available online) introduced the concept and remains the most precise treatment. For collective problem solving: Scott Page's The Difference: How the Power of Diversity Creates Better Groups, Firms, Schools and Societies (2007, Princeton) is the most rigorous account of why and when diverse groups make better decisions than homogeneous ones. For decision making under uncertainty: Phil Rosenzweig's The Halo Effect (2007) is the most accessible treatment of how outcome bias distorts learning from business and policy decisions. Annie Duke's Thinking in Bets (2018, Portfolio) applies poker strategy to decision-making under uncertainty in an accessible and engaging way.
