What command terms do

Every question in Digital Society starts with a command term: a verb or phrase such as outline, explain or evaluate that sets the task. The command term decides what kind of thinking the answer must show, and so how much it can earn. Two questions on the same topic can ask for very different answers. "Outline how a food delivery app assigns orders to riders" wants a short, accurate account. "Evaluate the use of algorithms to manage delivery riders" wants strengths and limitations weighed against each other and a judgement.

The course uses eighteen command terms, grouped into three assessment objective levels. AO1 terms test knowledge and understanding, AO2 terms test application and analysis, and AO3 terms test evaluation and synthesis. Each part of a question is set at one level, and any term from that level may appear. The level of a term shows the minimum that the answer must do.

The command term sets the ceiling of an answer. A brilliant description earns little in a question that asks you to evaluate, and an evaluation wastes time in a question that asks you to state. Underline the command term before reading anything else in the question.

The three levels build on each other, as the ladder diagram shows. An AO3 answer still needs the accurate knowledge of AO1 and the reasoning of AO2, and then adds weighing and judgement on top.

Staircase of three boxes. AO1 Knowledge and understanding: define, identify, describe, outline, state. AO2 Application and analysis: analyse, distinguish, explain, suggest. AO3 Evaluation and synthesis: compare, contrast, discuss, examine, evaluate, justify, recommend, to what extent.Staircase of three boxes. AO1 Knowledge and understanding: define, identify, describe, outline, state. AO2 Application and analysis: analyse, distinguish, explain, suggest. AO3 Evaluation and synthesis: compare, contrast, discuss, examine, evaluate, justify, recommend, to what extent.
The three assessment objective levels and their command terms. Each level includes the skills of the level beneath it, so an evaluation still rests on accurate knowledge and clear explanation.

The worked examples on command terms all use one topic, so the differences between terms stand out: food delivery and ride-hailing platforms that manage workers through apps, part of the gig economy.

AO1: knowledge and understanding

AO1 terms ask what something is, what it does or what happened. They do not ask why, and they do not ask for opinions. The skill is precision: the right term, the right detail, and nothing that wastes time.

Command term

Meaning in plain words

What the response looks like

State

Give a name, value or short answer, with no explanation

A word or a short phrase per mark

Define

Give the exact meaning of a word, phrase or concept

One precise sentence that would fit a glossary

Identify

Pick out an answer from a number of possibilities, often from a stimulus

A short phrase per point, taken from or matched to the material

Outline

Give a brief account or summary

Two or three linked sentences for each point

Describe

Give a detailed account

Several sentences with specific features, steps or characteristics

The difference between outline and describe is one of detail, not of kind. Neither asks for reasons. The difference between state and identify is smaller still: identify usually means choosing from material provided, such as a stimulus or source.

Worked example

Worked example. Three AO1 questions on the same topic. Compare what each one wants.

  1. State one type of data a food delivery app collects about its riders. [1]

  2. Outline how a food delivery app assigns an order to a rider. [2]

  3. Describe how a food delivery app monitors the performance of its riders. [4]

Model answers
  1. Location data from the rider's phone (GPS).

  2. When a customer places an order, the app uses the location of the restaurant and of available riders to find a nearby rider. The order is offered to that rider, who can accept or reject it within a short time.

  3. The app records each rider's GPS location throughout a shift, so it knows how long each delivery takes and whether the rider follows the suggested route. It logs how many orders the rider accepts and rejects, and how often the rider is late. Customers and restaurants rate the rider after each delivery. These records are combined into performance measures, such as acceptance rate and average rating, which the platform can use to decide which riders receive the most orders.

The first answer needs only a phrase. The second gives a short sequence. The third gives four distinct monitoring methods and says what is recorded in each, which is the detail that describe asks for. None of them gives reasons or judgements, because none is needed.

Common mistake

Writing a full paragraph for a state or identify question. One mark is given for each correct item, and extra explanation earns nothing. Save the time for the parts of the paper that reward depth.

AO2: application and analysis

AO2 terms ask for knowledge to be applied to a particular case, showing how or why something happens. The key word is because: every AO2 answer contains reasons, causes or consequences, linked to the situation in the question.

Command term

Meaning in plain words

What the response looks like

Explain

Give a detailed account that includes reasons or causes

A point, the reason it happens, and the consequence, linked to the case

Analyse

Break something down to show its essential parts or structure

The issue split into elements (causes, stakeholders, stages), with the links between them shown

Distinguish

Make the differences between two or more things clear

Paired statements on the same feature: "X does…, whereas Y does…"

Suggest

Propose a possible answer, solution or reason

A plausible idea, briefly justified, applied to the scenario

Explain is the most common AO2 term. A reliable pattern is point, reason, consequence: say what happens, say why it happens, then say what it leads to for a named group. Analyse asks for more structure: the answer separates the issue into parts and shows how they interact. Suggest is used when there is no single correct answer, so any reasonable idea that fits the scenario and is supported by a reason can earn credit.

Worked example

Worked example. A description and an explanation answer the same prompt. Which one fits the question "Explain one way in which rating systems can disadvantage delivery riders. [3]"?

Answer A: Customers give riders a score out of five after each delivery. The scores are added up and shown on the rider's profile. Riders with low scores are noticed by the platform.

Answer B: Customers rate riders after each delivery, but the rating can reflect things outside the rider's control, such as a restaurant preparing food slowly or bad weather. Because the platform uses average ratings to decide who receives orders or whose account is deactivated, a rider can lose income for delays they did not cause. Riders have little power to challenge this, as the rating comes from customers they cannot contact.

Commentary

Answer A describes the rating system but never says why it disadvantages riders, so it answers a describe question. Answer B gives the point (ratings reflect factors outside the rider's control), the reason it matters (ratings drive allocation and deactivation) and the consequence for a named group (lost income, no way to challenge). That three-step chain is what explain asks for, and it matches the three marks.

AO3: evaluation and synthesis

AO3 terms ask for judgement. The answer weighs evidence, considers more than one side and reaches a conclusion that follows from the argument. These terms appear in the higher-mark parts of each paper. Most of those parts are marked with markbands as well as a markscheme, so the quality of the whole argument counts, not only the number of points.

Command term

Meaning in plain words

What the response looks like

Compare

Show the similarities between two or more items, referring to all of them throughout

Point-by-point similarities, never two separate summaries

Contrast

Show the differences between two or more items, referring to all of them throughout

Point-by-point differences

Compare and contrast

Show both similarities and differences, referring to all items throughout

Each paragraph covers one theme and both items, with a word such as "both" or "whereas"

Discuss

Give a balanced review of a range of arguments or factors, with a clear, supported conclusion

Several arguments on different sides, each supported, then a stated conclusion

Evaluate

Weigh up strengths and limitations

Strengths and limitations set against each other, leading to an appraisal

Examine

Consider an argument or concept so that its assumptions and interrelationships become clear

Questions what the claim takes for granted and how its parts connect

Justify

Give valid reasons or evidence for an answer or conclusion

A position, then the strongest reasons and evidence for it

Recommend

Present an advisable course of action, with supporting evidence or reasons, for a given situation

A specific action, who should take it, why, and its likely trade-offs

To what extent

Consider the merits or otherwise of an argument, with a clear conclusion backed by evidence and sound argument

A judgement of degree ("largely", "only when…"), argued from both sides

Several of these terms look similar, but they reward different emphases. Discuss and to what extent both need a balanced review and a conclusion; to what extent also asks how far, so the conclusion should be a matter of degree rather than yes or no. Evaluate centres on strengths and limitations. Examine is the least familiar. It asks for the assumptions under a claim to be uncovered, for example by showing that "algorithms are neutral" assumes that the data they learn from is neutral.

Worked example

Worked example. Four AO3 questions on the same topic. Write the opening sentence of each answer so that it shows the demand of the command term.

  1. Evaluate the use of algorithms to manage delivery riders.

  2. To what extent do gig platforms give workers more control over their working lives?

  3. Examine the claim that app-based work is "self-employment".

  4. Recommend one step a city government could take to protect delivery riders.

Model openings
  1. Algorithmic management allows platforms to match thousands of orders to riders in seconds and gives riders flexible hours, but its strengths depend on data and rules that riders cannot see or challenge, which limits its fairness.

  2. Gig platforms give workers control over when they work, but much less control over how they work and what they earn, so they increase control only to a limited extent.

  3. The claim that app-based work is self-employment assumes that riders run their own businesses, but this assumption weakens when the app sets prices, assigns tasks and can deactivate accounts.

  4. The city should require platforms operating in it to explain to each rider, in plain language, why their account has been suspended and to offer review by a human, because this addresses the most serious loss riders face while leaving the flexible model in place.

Each opening shows the reader at once that the answer will weigh (1), judge a degree (2), uncover an assumption (3) or propose an action with a reason (4).

Exam tip

In the longest parts of each paper, an answer that analyses well but never judges usually stays in the middle markband. The top band asks for evaluation and synthesis: a judgement that pulls the arguments together. State your judgement in the first paragraph and return to it in the last.

Choosing and using real-world examples

A real-world example is a specific, existing case involving digital systems: a named app, platform, law, event, company or organisation, in a real place and time. Real-world examples are the main evidence in Digital Society answers. Some questions ask for one directly ("Refer to a real-world example you have studied"); in others, a good example is what turns a general claim into a supported one.

What makes an example specific

A specific example answers four questions: what digital system, who was involved, where and when, and what happened. "Social media spreads hate speech" answers none of them. "Facebook in Myanmar, where a UN fact-finding mission reported in 2018 that the platform had been used to spread hate speech against the Rohingya, and Facebook later accepted that it had not done enough to prevent this" answers all four.

Weak

Specific

"Gig apps exploit workers."

"In Uber BV v Aslam (2021), the UK Supreme Court ruled that Uber drivers were workers entitled to the minimum wage and holiday pay, partly because the app set fares and could log drivers off."

"Algorithms can be biased against workers."

"In December 2020 a court in Bologna, Italy, ruled that Deliveroo's system for ranking riders discriminated against them, because it penalised riders who cancelled booked shifts without considering why, for example illness or a strike."

"Governments are starting to regulate platforms."

"The EU Platform Work Directive (2024) presumes that platform workers are employees when the platform controls their work, and requires human oversight of important automated decisions, such as deactivating an account."

Explaining the example in relation to the question

Naming an example is not enough. The example must be explained in relation to the question, so the reader sees what it proves. A useful test is to ask "so what?" after the example. The answer to that question is the sentence that earns the credit.

Worked example

Worked example. The question is: "To what extent do gig platforms give workers more control over their working lives?" Use the Uber ruling as evidence.

Model paragraph

Gig platforms present drivers as independent, but the 2021 Uber BV v Aslam ruling in the UK suggests that the app holds much of the control. The Supreme Court found that Uber set the fares, fixed the terms of the contract and could penalise drivers who rejected too many trips, so drivers could not increase their earnings through their own decisions, as a business owner could. This shows that the flexibility to log on and off does not amount to control over working life, because the platform still decides the price of the work and the conditions for keeping access to it.

The bold sentence is the "so what?". Without it, the paragraph would only report a court case. With it, the case becomes evidence for a partial judgement on the question.

Building an example bank

Examples are easier to recall under pressure if they are prepared in advance and organised. A bank of about 15–25 well-understood examples, spread across the content topics and contexts, gives enough choice for most questions. For each example, record the same set of facts.

Field

Example: Deliveroo ruling, Bologna

Digital system

Deliveroo's rider-ranking algorithm and booking app

People and communities

Food delivery riders in Italy; the trade unions that brought the case

Where and when

Bologna, Italy; ruling in December 2020

What happened

The court found the ranking discriminatory because it treated every cancellation the same way, whatever the reason

Concepts it shows

Power, values and ethics, systems

Content and contexts

Algorithms, data; economic, political

Best used for

Questions on algorithmic bias, fairness at work, accountability, regulation

Tip

Choose examples from several regions of the world, not only from one country. A bank that includes cases from Africa, Asia, Latin America and Europe lets you answer questions about global inequalities and shows that impacts differ between places.

Common mistake

Using a hypothetical example ("Imagine a company that…") where a real one is asked for. A scenario in the stimulus is not a real-world example either. When the question asks for a real-world example you have studied, it must be a named, existing case from outside the paper.

Impacts and implications

Impacts are the effects and outcomes of digital systems: what has happened or is happening to people and communities. Implications are the opportunities and risks that follow: what could happen, what it means for policy, law or ethics, and where things might go next. The two overlap and inform each other, but separating them makes an answer more precise.

Impact

Implication

Time

Present or past

Future or possible

Typical wording

"has reduced", "led to", "resulted in"

"could", "risks", "creates an opportunity for", "raises the question of"

Gig work example

Riders' incomes vary from week to week because orders are allocated by algorithm

Workers without stable income may be unable to obtain loans or tenancies; governments may lose tax and social insurance revenue

A strong answer moves from impact to implication. It shows what has happened to a named group, then what that opens up or puts at risk. The Uber ruling is an impact for drivers in the UK (they gained minimum wage rights); its implication is that platforms in other countries face pressure to reclassify their workers, and that their business model may become more expensive.

Exam tip

When a question asks for implications, write about consequences that have not fully happened yet, such as risks, opportunities, ethical questions or legal changes. When it asks for impacts, give effects that have happened, ideally with evidence. Using both words correctly shows accurate use of course terminology, which the markbands reward.

Concepts, content and contexts in answers

Digital Society is organised around three lenses: concepts (change, expression, identity, power, space, systems, values and ethics), content (data, algorithms, computers, networks, media, artificial intelligence, robots) and contexts (cultural, economic, environmental, health, human knowledge, political, social). Questions are rarely labelled with these headings. Using them in an answer, however, adds analysis that a plain description lacks.

  • Content gives the technical accuracy: explaining that the platform uses GPS data and a ranking algorithm is more precise than "the app tracks riders".

  • A concept gives the angle of analysis. Through the concept of power, the question becomes who controls the data and who can challenge decisions. Through identity, it becomes whether riders see themselves as entrepreneurs or employees.

  • A context places the impacts. In the economic context, the issue is income security; in the political context, it is regulation and collective action.

Use concepts as tools, not labels. "This relates to the concept of power" earns little. "Through the concept of power, the ruling shows that control over pricing data, not ownership of a car, decided whether drivers counted as workers" uses the concept to make a point.

Claims, counter-claims and perspectives

A claim is a statement presented as true, which can be supported or challenged with evidence. A counter-claim is a claim that disagrees with or qualifies another claim. A perspective is the position from which a person or group sees an issue, shaped by their role, interests, values and experience. These three ideas are central to the longer answers in every paper.

Stakeholder

Perspective

Typical claim

Platform company

Business offering a service to independent contractors

"Flexible app-based work lets people earn on their own terms."

Rider

Worker whose income depends on the app

"The app controls my pay and can remove me without explanation."

Customer

User wanting fast, cheap service

"Delivery apps give access to more restaurants at any hour."

Regulator

Public body balancing innovation and protection

"Platform work needs rules on employment status and automated decisions."

The stakeholders in the table see different parts of the same system, which is why their claims differ. A good answer treats counter-claims seriously. It states the strongest version of the opposing view, gives its evidence, and then explains why it does or does not change the judgement. A counter-claim that is mentioned and immediately dismissed ("Some people disagree, but this is wrong") adds nothing.

Common mistake

Treating a counter-claim as a list of disadvantages. A counter-claim answers a specific claim. If the claim is "algorithmic management is efficient", the counter-claim is not "riders are underpaid" but "the efficiency is measured from the platform's perspective, and it shifts the cost of waiting time and risk onto riders".

Structuring an evaluation and reaching a judgement

An evaluation is built from linked paragraphs, each of which advances the argument. The chain in the evaluation diagram works for one paragraph or for a whole answer: a claim, evidence from a real-world example, an explanation that links the evidence to the question, a counter-claim, and then weighing that leads to a judgement.

Six boxes linked by arrows: claim, evidence, explanation (bracketed as support), counter-claim, weighing (bracketed as balance), and a shaded judgement box: a clear position with its conditions.Six boxes linked by arrows: claim, evidence, explanation (bracketed as support), counter-claim, weighing (bracketed as balance), and a shaded judgement box: a clear position with its conditions.
The steps of an evaluative paragraph. The weighing step is what turns a balanced list into an evaluation, because it says which side matters more and why.

Weighing

Weighing means deciding which argument is stronger and saying why. Useful criteria for weighing include:

  • Scale: how many people are affected, and how seriously.

  • Who is affected: whether the benefits and harms fall on the same group, or whether one group gains while another loses.

  • Time: whether an effect is short-term or long-lasting.

  • Evidence: how strong and reliable the evidence for each side is.

  • Reversibility: whether a harm can be corrected, such as through an appeal.

A supported, conditional judgement

The best judgements are clear but conditional. They state a position and the conditions under which it holds. "Algorithmic management is acceptable" is a position with no limits. "Algorithmic management is acceptable for allocating orders, but not for deactivating accounts unless a human reviews the decision" is a judgement that shows the weighing behind it. Phrases such as "to a large extent", "only where", "provided that" and "in the short term, but" signal a judgement of degree.

Worked example

Worked example. Write a concluding paragraph for: "To what extent should platforms be allowed to manage workers through algorithms? [8]"

Model conclusion

Platforms should be allowed to use algorithms to allocate work, because matching orders to riders at speed is the service customers rely on and riders value the flexibility it creates. They should not be allowed to make decisions that remove a worker's income without human review and an explanation. The Deliveroo ruling in Bologna shows that a ranking system that ignores the reasons for a cancellation can discriminate, and the EU Platform Work Directive responds to exactly this by requiring human oversight of significant automated decisions. Algorithmic management is therefore acceptable to the extent that workers can see and challenge the decisions that matter most to them.

Commentary

The conclusion answers the command term (it gives a degree, not a yes or no), separates two uses of the algorithm, uses two real-world examples as evidence rather than decoration, and ends with a condition. It does not introduce a new argument or repeat the whole answer.

Exam tip

A conclusion should follow from the argument. If the answer has shown strong evidence on both sides, a conditional judgement ("only where…") is more convincing than a one-sided one. Avoid sitting on the fence: "there are advantages and disadvantages" is not a judgement.
