Detailed notes on Component 3: Team Project for Cambridge International A Levels Global Perspectives & Research, covering key concepts, explanations, examples, and exam-focused revision points.

Individual Research & Solution — Cambridge AS & A Level Global Perspectives & Research 9239 (Component 3)

Once the team has set up the problem and given you a distinct perspective, this is where your individual work begins. You research the shared problem from your one assigned perspective, use your findings to develop a proposed solution, and evaluate that solution's feasibility and limitations. This is the AO1 core of your presentation — the research and reasoning behind what you'll say. These notes show you how to research a single perspective well, turn research into a concrete, evidence-based solution, and evaluate it honestly so your proposal is realistic rather than idealistic.

At a glance

This is your INDIVIDUAL work: research the shared problem from your ONE assigned perspective.
Research feeds AO1 (40% of Component 3) — the analysis and evaluation behind your presentation.
Use credible, relevant sources on your perspective; record them for referencing and evaluation.
Turn your findings into a PROPOSED SOLUTION — concrete and grounded in your research, not a vague wish.
EVALUATE your solution: assess its feasibility (can it realistically be done?) and its limitations.
Stay in your lane: research YOUR perspective deeply; the team covers the others.
A good solution is specific, achievable and honestly evaluated — realistic beats idealistic.
This research-and-solution work becomes the substance of your individual presentation (next subtopic).

What you’ll learn

Mapped to the Cambridge International A Level 9239 syllabus (2026-2028).

Research the problem from one assigned, distinct perspective.
Use research findings to develop a proposed solution.
Evaluate the feasibility and limitations of the proposed solution.

Researching the problem from your one assigned perspective

Go deep on your single perspective using credible, relevant sources — this is the AO1 foundation of your presentation.

The team gave you one distinct perspective on the shared problem. Your job now is to research that perspective in depth — not the whole problem, and not the other members' perspectives (they cover those).

What good research looks like here:

Focused on your perspective. If your perspective is economic, research the costs, funding, employment and financial trade-offs of the problem and possible responses — not the environmental or social angles.
Credible and relevant sources. Use reputable sources (reports, studies, reputable journalism, data, expert commentary) that genuinely bear on your perspective and the local problem.
Analysed, not just collected. Pull out the key arguments and evidence, and note how strong each is — this is the AO1 (research, analysis and evaluation) skill, worth 40% of Component 3.

Ground the global perspective in the local problem. Remember the problem is local with global relevance. Strong research connects the two: use the wider global evidence on your perspective and apply it to your specific local context. For example, global data on the economics of recycling, applied to your city's beach-plastic problem.

Record sources as you go. Keep full reference details and a short note on each source's credibility and relevance. You will need to refer to your research in the presentation, and evaluating your sources is part of the AO1 marks. Recording as you research (not at the end) also protects academic integrity.

Depth over breadth. Because you cover only one perspective, you can — and should — go deeper than you could on a whole issue. A focused, well-evidenced single perspective is exactly what the component asks for.

Research your ONE assigned perspective in depth — not the whole problem.
Use credible, relevant sources and analyse the arguments/evidence (AO1, 40%).
Connect the global evidence on your perspective to the specific local problem.
Record sources (details + credibility notes) as you go — you'll refer to them in the presentation.

Turning research into a proposed solution

Use your findings to propose a concrete, evidence-based solution from your perspective — not a vague wish.

Research is not the end point — you must use your findings to develop a proposed solution to the problem, seen from your perspective.

What makes a strong proposed solution:

Grounded in your research. The solution follows from the evidence you gathered — you can show why your research points to this response.
From your perspective. It reflects your assigned lens (e.g. an economic perspective might propose a funding or incentive scheme; an environmental one a specific reduction measure; a policy one a regulation).
Concrete and specific. A real, describable action — "introduce a deposit-return scheme for plastic bottles in our city" — not a vague aspiration ("people should care more about the environment").
Relevant to the local problem. It addresses your community's version of the problem, informed by the wider global evidence.

From evidence to solution — the link to make explicit:

"My research shows that [evidence/finding]; therefore, from an [economic/environmental/…] perspective, I propose [specific solution], because [how the evidence supports it]."

Making this evidence → solution link explicit is what turns a list of research into a reasoned proposal — and it is exactly the AO1 reasoning the presentation rewards.

One solution, well developed. You are proposing your own solution from your own perspective. It does not have to solve the entire problem alone — together, the team's perspectives and solutions give a rounded response. Your task is to make your proposal specific, evidenced and clearly reasoned.

Use your research to develop a concrete, specific proposed solution.
The solution must reflect your assigned perspective and the local problem.
Make the evidence → solution link explicit (research shows X, so I propose Y because…).
Develop one solution well; the team's solutions together give a rounded response.

Evaluating your solution: feasibility and limitations

Honestly assess whether your solution can realistically work, and be clear about what it can't do.

A proposal is only convincing if you evaluate it honestly. Component 3 asks you to assess your solution's feasibility and its limitations — this evaluation is a key part of AO1 and shows mature, realistic thinking.

Feasibility — can it realistically be done? Consider:

Cost / resources — is it affordable? Who pays?
Practicality — can it actually be implemented in your local context? By whom?
Time — how long would it take to have an effect?
Acceptance — will the people affected (residents, businesses, authorities) support it?

Limitations — what can't it do? Be honest about:

Scope — which parts of the problem it does not address.
Side effects / trade-offs — costs it creates from other perspectives (e.g. an economic solution with environmental downsides).
Uncertainty — where your evidence is thin or the outcome is not guaranteed.
Dependencies — what has to be true for it to work.

Realistic beats idealistic. A solution you have honestly evaluated — acknowledging cost, practicality and what it can't fix — is far more convincing than a "perfect" solution presented as flawless. Examiners reward candidates who can see the limits of their own proposal.

Evaluate feasibility: cost, practicality, time, and acceptance by those affected.
State limitations: what it doesn't fix, trade-offs, uncertainty, and dependencies.
Honest evaluation shows mature, realistic thinking (AO1).
A realistically evaluated solution beats a 'perfect' one presented as flawless.

From research and solution to your presentation

This research, proposal and evaluation are the substance of your individual presentation.

The individual research and solution you produce here is the content of your individual presentation (the next subtopic). It is worth being clear about how they connect.

What flows into the presentation:

your perspective on the shared problem;
the research and evidence you gathered (which you refer to);
your proposed solution; and
your evaluation of its feasibility and limitations.

AO1 lives here. The quality of this research-and-solution work determines the AO1 marks (40% of the component) that your presentation earns. A well-researched, clearly reasoned, honestly evaluated proposal gives you strong material; thin research or a vague solution leaves the presentation with little substance, however polished the delivery.

Prepare to defend it. Because you present individually, you own every claim. Make sure you understand your own evidence well enough to explain why your solution follows from it and where its limits lie. This confidence comes from doing the research and evaluation properly now.

Keep it organised. Structure your material as: perspective → key research findings → proposed solution → feasibility → limitations. That order will also serve as the backbone of your presentation's main body — so good organisation now saves work later.

Your research, solution and evaluation are the substance of the individual presentation.
AO1 (40%) is earned by the quality of this research-and-solution work.
You own every claim — understand your evidence well enough to explain and defend it.
Organise as perspective → findings → solution → feasibility → limitations.

Quick recap

Research the shared problem from your ONE assigned perspective, using credible, relevant sources (AO1, 40%).
Connect the global evidence on your perspective to the specific local problem.
Use your findings to develop a concrete, specific proposed solution — make the evidence → solution link explicit.

How it’s examined

Individual research and solution supply the AO1 substance of Component 3 (the Team Project), which is worth 40 marks overall (individual Presentation 30 + individual Reflective Paper 10; AO1 40%, AO2 25%, AO3 35%). After the team has set up the shared problem and allocated distinct perspectives, each candidate individually researches the problem from their one assigned perspective, uses the findings to develop a proposed solution, and evaluates that solution's feasibility and limitations. This work is not assessed as a separate written piece — it is the content the candidate then presents individually — so its quality directly determines the AO1 marks the presentation can earn. Examiner guidance rewards focused, well-evidenced research on a single perspective, a concrete solution that clearly follows from the evidence, and an honest evaluation of feasibility and limitations (realistic proposals score better than idealistic ones presented as flawless). Because the presentation is authenticated coursework, the research, solution and evaluation must be the candidate's own work, with sources recorded and referred to.

Step-by-step worked examples — Individual Research and Solution

Step-by-step solutions to past-paper-style questions on individual research and solution, written exactly the way a tutor would explain them at the board.

Question type:

1Keeping to your assigned perspective
Getting startedIdentify & classify• Component 3, research
Question
Your assigned perspective on 'beach plastic waste' is economic. Which of these research notes belong to your perspective? (a) cost of beach clean-ups; (b) plastic's effect on marine life; (c) tourism revenue lost to dirty beaches; (d) how microplastics enter the food chain.
Step-by-step solution
1. Step 1
  Identify your lens. Economic = costs, revenue, funding, jobs.
2. Step 2
  Test each note. (a) cost — economic ✓; (c) tourism revenue — economic ✓; (b) marine life — environmental ✗; (d) food chain — environmental/health ✗.
3. Step 3
  Conclude. Research (a) and (c); leave (b) and (d) to teammates.
Answer
(a) cost of clean-ups and (c) tourism revenue lost belong to your economic perspective. (b) effect on marine life and (d) microplastics in the food chain are environmental/health angles for other members. Research your perspective deeply and leave the others to your teammates.
Examiner tip
Component 3 assigns one distinct perspective per member so each can go deep. Straying into others' angles produces shallow research and duplicates teammates' work.
2Connecting global evidence to the local problem
Getting startedMulti-step problem• Component 3, research
Question
Your perspective is environmental, on 'food waste in our school'. You find global data that food waste causes ~8–10% of greenhouse-gas emissions. How do you use it well?
Step-by-step solution
1. Step 1
  Don't just quote the global figure. Connect it to the local problem.
2. Step 2
  Apply it locally. Estimate/relate the school's waste to that global pattern.
3. Step 3
  Make it relevant. Show the local action contributes to (or mirrors) the global issue.
Answer
Use the global figure to frame the significance, then connect it to the local case: 'Food waste causes roughly 8–10% of global greenhouse-gas emissions; the food our school discards is a small but real part of that pattern, so reducing it locally addresses a genuinely global problem.' The global evidence gives significance; the local application makes it relevant to the project.
Examiner tip
The problem is local with global relevance — strong research links the two, using global evidence to show why the local action matters rather than leaving the global figure floating.
3Making the evidence → solution link explicit
Building confidenceMulti-step problem• Component 3, solution
Question
Your economic-perspective research on beach plastic finds that deposit-return schemes elsewhere raised bottle return rates to over 90%. Turn this into a proposed solution with the reasoning shown.
Step-by-step solution
1. Step 1
  State the evidence/finding. Deposit-return schemes achieve >90% return rates.
2. Step 2
  Draw the solution from it (your perspective). Propose a local deposit-return scheme.
3. Step 3
  Show the link. Explain why the evidence supports the proposal.
Answer
"My research shows deposit-return schemes elsewhere have raised bottle return rates above 90%; therefore, from an economic perspective, I propose our city introduce a deposit-return scheme for plastic bottles, because a small refundable deposit gives people a financial incentive to return bottles rather than discard them on beaches." The proposal follows explicitly from the evidence.
Examiner tip
A reasoned proposal makes the evidence→solution link explicit ('research shows X, so I propose Y because…'). This turns a list of research into an AO1-worthy argument.
4From vague aspiration to concrete solution
Building confidenceMulti-step problem• Component 3, solution
Question
A student proposes: 'People should care more about food waste.' Explain why this is not a usable solution and rewrite it as a concrete proposal.
Step-by-step solution
1. Step 1
  Diagnose. It's a vague aspiration — not a describable action, and can't be evaluated for feasibility or limitations.
2. Step 2
  Make it concrete. Name a specific, implementable action in the local context.
3. Step 3
  Keep it to the perspective. e.g. behavioural: a specific programme.
Answer
'People should care more' is a vague aspiration, not a solution — it names no action and cannot be evaluated. Concrete rewrite: 'Introduce a school 'take what you'll eat' campaign with smaller default portions and a weekly waste-tracking display in the canteen.' This is a specific, describable action that can be evaluated for feasibility and limitations.
Examiner tip
A proposal must be a concrete, describable action so it can be evaluated. Aspirations ('people should care') cannot be assessed for feasibility — a common weakness.
5Evaluating feasibility
StretchMulti-step problem• Component 3, feasibility
Question
Evaluate the feasibility of your proposed local deposit-return scheme for plastic bottles.
Step-by-step solution
1. Step 1
  Cost/who pays. Set-up costs for collection points; funded partly by unclaimed deposits.
2. Step 2
  Practicality. Needs retailers/collection points to participate; administration required.
3. Step 3
  Time. Takes months to set up; return habits build over time.
4. Step 4
  Acceptance. Residents likely supportive; some retailers may resist the admin burden.
Answer
Feasibility: the scheme is workable but not costless. It needs set-up investment in collection points (partly self-funded through unclaimed deposits), the cooperation of retailers to host returns, and several months to establish before return habits form. Residents are likely to accept a small refundable deposit, though some retailers may resist the extra administration. On balance it is feasible with council and retailer support.
Examiner tip
Feasibility means engaging with cost, practicality, time and acceptance — not just asserting 'it would work'. A specific solution (from the previous step) makes this evaluation possible.
6Evaluating limitations and trade-offs
StretchMulti-step problem• Component 3, limitations
Question
State the limitations of your deposit-return scheme, including any trade-off that connects to another team perspective.
Step-by-step solution
1. Step 1
  Scope. It targets bottles, not all plastic waste (packaging, microplastics).
2. Step 2
  Trade-off. Adds cost/admin for small retailers — an economic downside your teammate's policy/social perspective might address.
3. Step 3
  Uncertainty/dependency. Depends on enough collection points and public participation.
4. Step 4
  Honesty. Acknowledge what it can't fix.
Answer
Limitations: the scheme only addresses plastic bottles, not other beach plastics (packaging, fishing gear, microplastics); it adds cost and administration for small retailers (a trade-off a policy/social perspective in my team could help address through support or exemptions); and its success depends on enough accessible collection points and public participation. So it is a valuable partial solution, not a complete one — which is why the team's other perspectives matter.
Examiner tip
Strong evaluation states scope limits, trade-offs (ideally linking to another team perspective), and dependencies. Acknowledging what the solution can't do shows realistic, integrative thinking — not weakness.

Model Answers — Individual Research and Solution

Component 3 is coursework — you research and present individually, so these are not questions from a past exam paper. Each is a worked exemplar showing how to research your assigned perspective, develop a concrete proposed solution, and evaluate its feasibility and limitations, with examiner-style notes tied to the mark scheme and assessment objectives (AO1, AO2, AO3).

Question 1
Component 3 team project (exemplar)
[EASY] Explain why, in Component 3, you research the shared problem from only one assigned perspective rather than covering the whole problem.
Model answer
In Component 3 each team member is allocated a distinct perspective on the shared problem, and researches only that perspective. This is because:

it lets each member go deep rather than shallow — a focused, well-evidenced single perspective is what the component rewards (AO1);

it avoids duplicating teammates' work — together the team's perspectives give a rounded view; and

each member presents individually, so your research must be your own distinct contribution.

Covering the whole problem would produce shallow research and overlap with others; researching one perspective in depth produces the strong, individual AO1 material the presentation needs.
Why this scores
Credit the reasons for a single-perspective focus: depth over breadth, no duplication, individual contribution. This is why Component 3 allocates distinct perspectives.
Question 2
Component 3 team project (exemplar)
[EASY] What makes a proposed solution 'concrete' rather than vague? Give one vague example and one concrete example.
Model answer
A concrete solution names a specific, describable action that could actually be implemented and therefore evaluated for feasibility and limitations. A vague solution only expresses a wish and cannot be evaluated.

Vague: "People should waste less food." (no action; cannot be assessed)

Concrete: "Introduce smaller default canteen portions plus a weekly food-waste tracker displayed to students." (a specific, implementable action)
Why this scores
Credit the distinction (specific, implementable, evaluable vs a wish) and a valid contrasting pair. Only concrete solutions can be evaluated for feasibility/limitations.
Question 3
Component 3 team project (exemplar)
[MEDIUM] Your assigned perspective on 'traffic congestion and air quality in our town centre' is environmental. Outline how you would research it and turn your findings into a proposed solution, showing the evidence→solution link.
Model answer
Research (environmental perspective): I would gather credible evidence on how town-centre traffic affects air quality — e.g. data on vehicle emissions and local pollution levels, and studies on measures such as low-emission zones or restricted-traffic streets in comparable towns — recording each source and its credibility. I would connect the wider global evidence on urban air pollution to our specific town-centre context.

From evidence to solution: "My research shows that low-emission zones in comparable towns have measurably reduced roadside pollution; therefore, from an environmental perspective, I propose our town introduce a low-emission zone in the centre, because restricting the most polluting vehicles directly targets the main source of the poor air quality my evidence identifies."

The solution is concrete (a low-emission zone), from my perspective (environmental), grounded in evidence (comparable-town data), and relevant to the local problem (our town centre) — with the evidence→solution reasoning made explicit.
Why this scores
Credit focused research on the one perspective (with sources), a concrete solution from that perspective, and an explicit evidence→solution link applied to the local context. This is the AO1 core of the presentation.
Question 4
Component 3 team project (exemplar)
[MEDIUM] For a proposed 'low-emission zone in the town centre', evaluate its feasibility and state two limitations.
Model answer
Feasibility. The scheme is feasible but demanding:

Cost/resources: it requires cameras/signage and enforcement — a real cost, though fines and reduced health costs offset it over time.

Practicality: it can be implemented by the local authority, but needs planning and public communication.

Time: several months to set up; air-quality benefits build gradually.

Acceptance: residents concerned about pollution may support it, but some drivers and businesses may resist.

Two limitations.

Scope: it targets vehicle emissions in the centre only — it does not address pollution from other sources or congestion outside the zone (which may simply shift).

Trade-off/equity: it may burden people who rely on older vehicles and cannot afford to upgrade — an economic/social downside another team perspective could help address (e.g. support schemes or exemptions).

Acknowledging these makes the proposal realistic rather than idealistic.
Why this scores
Credit a genuine feasibility evaluation (cost, practicality, time, acceptance) and specific limitations (scope + a trade-off, ideally linked to another perspective). Honest evaluation is rewarded; a 'flawless' solution is not.
Question 5
Component 3 team project (exemplar)
[HARD] Your team's problem is 'single-use plastic waste in our city', and your assigned perspective is political/policy. Produce your individual research-and-solution work: outline your research, propose a concrete solution with the evidence→solution reasoning, and evaluate its feasibility and limitations.
Model answer
Research (political/policy perspective). I would research how governments and local authorities have used policy to cut single-use plastics — e.g. bans on specific items (bags, straws, polystyrene), charges/levies, and extended producer responsibility rules — gathering evidence on their effects and enforcement, and recording each source with a note on its credibility. I would connect the global policy evidence to my city's specific context (what powers our local authority actually has). Global evidence shows, for example, that plastic-bag charges in several countries cut bag use by 80%+.

Proposed solution (with reasoning). "My research shows that charges and targeted bans have sharply reduced single-use plastic use where enforced; therefore, from a policy perspective, I propose our city introduce a phased by-law: first a charge on single-use plastic bags and a ban on polystyrene food containers, backed by clear enforcement, because the evidence shows these targeted, enforceable measures change behaviour where general appeals do not."

Feasibility.

Cost/practicality: implementable through existing local-authority powers; enforcement costs partly offset by charge revenue and penalties.

Time: phased introduction over 12–18 months allows businesses to adapt.

Acceptance: likely public support for charges/bans on visible items; some retailer resistance to compliance costs.

Limitations.

Scope: it targets specific items, not all single-use plastic; producers may switch to non-covered items.

Enforcement dependency: the policy only works if actually enforced — weak enforcement would undermine it.

Trade-off: compliance costs fall on small businesses — an economic downside a teammate's economic perspective could address through support or phasing.

Overall. A phased, enforceable policy is a feasible and evidence-based response from the political perspective, but it is a partial solution whose success depends on enforcement and which needs the team's other perspectives (economic support, behaviour change, environmental measures) for a rounded response.
Why this scores
Top-band exemplar: focused single-perspective research with sources and a local link, a concrete evidence-based solution with the explicit evidence→solution reasoning, and an honest feasibility/limitations evaluation (including a cross-perspective trade-off). This is exactly the AO1 substance a strong individual presentation is built on.
Question 6
Component 3 team project (exemplar)
[HARD] A student's Component 3 work: they researched the whole problem rather than their assigned perspective; their solution is 'we should all do our part'; and they claim it 'will completely solve the problem'. Diagnose each weakness and explain how to fix it.
Model answer
Three weaknesses, each limiting AO1:

1. Researched the whole problem, not their assigned perspective.

Why it fails: the research is shallow and duplicates teammates' work; Component 3 assigns one distinct perspective so each member can go deep.

Fix: focus all research on the one assigned perspective, using credible sources, and leave the other angles to teammates.

2. Vague 'solution' ('we should all do our part').

Why it fails: it is an aspiration, not a describable action, so it cannot be evaluated for feasibility or limitations.

Fix: propose a concrete, specific action grounded in the research and drawn explicitly from the evidence (evidence→solution link).

3. Claiming it 'will completely solve the problem'.

Why it fails: it ignores feasibility and limitations and reads as naïve — real problems are rarely fully solved by one measure from one perspective.

Fix: evaluate the solution honestly — its feasibility (cost, practicality, time, acceptance) and its limitations (scope, trade-offs, dependencies) — and present it as a valuable partial contribution alongside the team's other solutions.

Overall: the student should narrow to their perspective and research it deeply, replace the aspiration with a concrete evidence-based proposal, and add an honest evaluation. Together these turn thin, over-claimed work into the focused, realistic, well-evidenced AO1 material the presentation needs.
Why this scores
Top band: identifies all three weaknesses (unfocused research, vague solution, over-claiming) and gives a correct, specific fix for each, tied to AO1. Recognising that honest evaluation (not a 'complete solution') is what scores is the key insight.

Key Definitions and Keywords — Individual Research and Solution

Definitions to memorise and the exact keywords mark schemes credit for individual research and solution answers — sharpened from recent examiner reports for the 2026 Cambridge International AS & A Level 9239 sitting.

Assigned perspective
Examiner keyword
The one distinct perspective on the shared problem that a team member is allocated and researches in depth (e.g. economic, environmental, political). Members do not research the whole problem.
Proposed solution
Examiner keyword
A concrete, describable action to address the problem, developed from the candidate's research and their assigned perspective — specific enough to be evaluated, not a vague aspiration.
Evidence → solution link
Examiner keyword
Making explicit how the research supports the proposal: 'my research shows X, so I propose Y because…'. Turns collected research into a reasoned, AO1-worthy argument.
Feasibility
Examiner keyword
Whether a proposed solution can realistically be implemented — judged by cost/resources, practicality, time to take effect, and acceptance by those affected.
Limitations
Examiner keyword
What a solution cannot do: parts of the problem it does not address, trade-offs/side effects, uncertainty in the evidence, and dependencies it relies on.
Trade-off
A cost a solution creates when viewed from another perspective (e.g. an economic solution with an environmental downside). Noting trade-offs shows integrative, realistic thinking.
Local–global link
Examiner keyword
Connecting the wider global evidence on a perspective to the specific local problem, so the research shows why the local action matters as part of a worldwide issue.
Credible source
Examiner keyword
A reputable, relevant source (report, study, data, expert commentary) used to support the perspective, recorded with its details and an assessment of its credibility.
AO1 in Component 3
Examiner keyword
Research, analysis and evaluation — 40% of Component 3. Earned through the quality of the individual research, the reasoning from evidence to solution, and the evaluation of the solution.
Realistic proposal
A solution presented with its feasibility and limitations honestly assessed, rather than as flawless. Realistic proposals score better than idealistic ones.

AO1 in Component 3

Realistic proposal

✕Researching the whole problem instead of your assigned perspective

✕Proposing a vague aspiration instead of a concrete solution

✕Presenting a solution without linking it to the research

✕Presenting the solution as flawless / a complete fix

✕Not evaluating feasibility at all

✕Quoting global evidence without connecting it to the local problem

✕Leaving research shallow because 'only the presentation is marked'
