How IGCSE marks this
Command words govern mark schemes: 'State' = 1 concise fact; 'Describe' = what happens; 'Explain' = why/how using scientific terminology.
Watch out for
Vague everyday wording ('it gets bigger') fails Cambridge mark schemes where exact terms ('rate of collisions increases') are required.
Lesson content
The papers test a skill, not a memory
History's marks are earned in three moves, and a candidate who can name them in their own words is already above half the cohort. First: what does the source say (its content). Second: what can be inferred from it, and from whom it came and why (its provenance). Third: how far it can be used for the question asked (its usefulness, which is never simply 'it is propaganda, so no'). The content of the depth study is the material these moves are performed on; it is not a substitute for them. So build a routine and apply it to every source in the paper, however familiar. Read it twice, and on the second pass underline the three words that carry the author's position. Say what it is, who made it, when, and for whom. Ask what it was meant to achieve, and therefore what it exaggerates or omits. Then answer the actual question with the part of the source that fits it, and add one thing the source does not tell you — the knowledge from your own study that puts it in context. That last step is where the top bands live: a source answer without outside knowledge is a comprehension answer.
Origin, purpose and the message
Origin is what the document is: a speech, a photograph taken for a newspaper, a private diary, a government poster, a statistic compiled by a colonial administration for its own records. Each type has a characteristic bias, and knowing the type is most of the judgment — a diary written for nobody is candid about motives and unreliable about scale; an official return is careful about numbers and silent about what the counters did not see. Purpose is what the author wanted the audience to do or believe, and it is inferred from the language, the medium and the moment of publication. Say the purpose in one sentence and then use the word 'because' — 'to persuade neutral countries that the other side began it, because the speech lists the enemy's movements and ignores its own'. Message is what the source actually communicates, which is often not what it intended: a recruiting poster meant to glorify service may reveal conscription's unpopularity in its insistence on cheerfulness. Marks are lost by treating 'it is biased' as a conclusion; the useful sentence is 'this makes it valuable as evidence of X, and unreliable as evidence of Y'.
A poster read in four sentences
The source: a government poster from the Second World War showing a woman in overalls lifting a shell casing, with a slogan about what a strong back does for the front. Question: 'What can a historian learn from Source A about the role of women in wartime industry?' One: it is a state-produced publicity poster, so it was made to encourage women into munitions work and to keep up production — its purpose is persuasion, not record. Two: it presents the work as healthy, skilled and respectable, which tells the historian what the authorities thought was attractive, and what they thought needed to be overcome. Three: it can be used as evidence that the state wanted women in heavy industrial roles, because recruiting material is only produced where labour is short — the inference is safer than anything about how women felt, which the poster cannot show. Four: it cannot be used as evidence of the numbers employed, the hours worked or the pay, and those have to come from employment returns, factory inspection reports and the wage orders, which do give the figures and which the poster's idealised image does not. That paragraph has content, provenance, a limit and a cross-reference to other evidence, which is the whole mark scheme in four sentences.
Useful for what? — the reliability question
The source is a colonial district officer's 1930 report to his superior explaining why tax revenue in his province fell. The question: 'How useful is Source B to a historian studying the economic effects of taxation in this region?' The answer that works keeps two things in view at once. It is highly useful as evidence of the administration's own explanation, because the officer had access to the figures, wrote for an internal reader with no reason to flatter anyone outside the service, and had an interest in showing that the shortfall was not his mismanagement — a motive that tells the historian which of his explanations to distrust. It is less useful as evidence of what the taxpayers experienced, because the report does not record their own accounts, and it is unreliable on scale, since 'many' and 'several' in that prose are administrative impressions rather than counts. Then the cross-reference: a trader's journal, the currency boards' returns or the mission records of the same years could confirm or contradict the officer's figures, and one of them would be evidence of the reaction the report minimises. The sentence to imitate is the structure, not the content: useful for X because…, less useful for Y because…, and the evidence that would test it is…
The Core routine, in five lines
What is it, who made it, for whom. What does it say, and what does it need the reader to believe. What can be inferred from it, and on what words that inference rests. What it cannot be used for, and what other evidence would test it. Then the answer, in the number of paragraphs the marks imply. The depth study you are examined on — its period, its places — is set in the syllabus for your examination year, and it is the content your teacher's material names. The routine above is what travels between papers, so practise it on sources from the study you actually have, including one whose purpose you dislike.
