IGCSE WJEC History: Quick Reference Formula Handbook | IGCSE WJEC 历史：公式定理速查手册

📚 IGCSE WJEC History: Quick Reference Formula Handbook | IGCSE WJEC 历史：公式定理速查手册

History may not have equations in the traditional sense, but every historian relies on a set of analytical ‘formulas’ to interpret the past. In the WJEC IGCSE History course, mastering the techniques for explaining causes, evaluating sources, and comparing interpretations is as essential as knowing the dates. This quick reference handbook turns the essential skills of historical reasoning into memorable formulas, helping you structure your thinking and write high-scoring exam answers. From the CAUSE formula to the CROSS-REFERENCE tool, each ‘theorem’ is explained with clear examples drawn from the Depth Studies, such as Germany 1918-1945 or the USA 1910-1929, and the Breadth Study of the Cold War. Use these formulas to turn evidence into argument and narrative into analysis.

历史学或许没有传统意义上的公式，但每位历史学家都依赖一套分析的「定理」来解读过去。在 WJEC IGCSE 历史课程中，掌握解释原因、评估史料和比较不同说法的技巧与记住日期同样重要。这本速查手册将历史推理的核心技能转化成便于记忆的公式，帮助你组织思路，写出得高分的考试答案。从「原因公式」到「互证工具」，每条「定理」都配有来自深度研究（如 1918-1945 年的德国或 1910-1929 年的美国）以及冷战广度研究的具体例子。用这些公式把证据变为论证，把叙事变为分析。

1. The CAUSE Formula | 原因分析公式

The most fundamental historical question is ‘Why did it happen?’. The CAUSE formula breaks down causation into three layers: Long-Term Factors + Short-Term Factors + Trigger Event. Long-term causes create the underlying conditions; short-term causes bring momentum; the trigger is the immediate spark that sets everything in motion. In an essay on the rise of Hitler, for instance, long-term factors include the Treaty of Versailles and economic instability, short-term factors include the Great Depression and political maneuvering in 1932, and the trigger was Hindenburg’s appointment of Hitler as Chancellor in January 1933.

最基本的历史问题是「为什么会发生？」。原因公式将因果关系分解为三个层次：长期因素 + 短期因素 + 触发事件。长期原因制造了深层条件；短期原因积蓄了动能；触发事件则是点燃一切的直接火花。例如，在关于希特勒崛起的论文中，长期因素包括《凡尔赛条约》和经济动荡，短期因素包括大萧条和 1932 年的政治操作，而触发事件正是 1933 年 1 月兴登堡任命希特勒为总理。

CAUSE = LT + ST + Trigger
Long-term: Versailles resentment, Weimar weaknesses, Nazi ideology.
Short-term: 1929 Wall Street Crash, unemployment, Reichstag fire.
Trigger: Enabling Act (March 1933).

原因 = 长期 + 短期 + 触发

长期：《凡尔赛条约》的怨恨、魏玛缺陷、纳粹意识形态。
短期：1929 年华尔街崩盘、失业、国会纵火。
触发：《授权法案》（1933 年 3 月）。

2. The CHANGE & CONTINUITY Formula | 变化与延续公式

Historians never view events in isolation; they track how things changed and what stayed the same. The CHANGE & CONTINUITY formula: Direction of Change (progress or decline?) + Pace (rapid or gradual?) + Areas of Continuity. In studying the impact of the New Deal in the USA, you might note that federal government power expanded dramatically (change), but racial segregation in the South and gender inequality showed strong continuity. Apply this formula to any period: 1920s prosperity to Depression, or Cold War détente to renewed tension.

历史学家从不孤立看待事件；他们追踪哪些变了，哪些保持原样。变化与延续公式：变化方向（进步还是倒退？）+ 速度（快速还是渐进？）+ 延续的领域。在研究美国新政影响时，可以发现联邦政府权力急剧扩张（变化），但南方的种族隔离与性别不平等显示了强大的延续性。把这一公式应用到任何时期：从二十年代繁荣到大萧条，或从冷战缓和到再度紧张。

Change = Direction + Pace + Scope
Continuity = institutions, social attitudes, economic structures that resisted change.
Example: Cold War – change: Cuban Missile Crisis increased communication (hotline); continuity: ideological rivalry remained.

变化 = 方向 + 速度 + 范围

延续 = 抗拒变化的制度、社会态度、经济结构。
例子：冷战——变化：古巴导弹危机后增加沟通（热线）；延续：意识形态对抗依旧。

3. The SOURCE EVALUATION Formula (O – P – C – V – L) | 史料评估公式（出处 – 目的 – 内容 – 价值 – 局限）

WJEC exams place heavy emphasis on analysing historical sources. The OPCVL method is a reliable ‘theorem’ for evaluation: Origin (who created it, when, where) + Purpose (why it was made) + Content (what it says and how) + Value (what it reveals about the period) + Limitations (what it misses or distorts). For a Nazi propaganda poster from 1936, Origin: Ministry of Propaganda, Berlin; Purpose: to glorify Hitler; Content: strong Aryan imagery; Value: insight into Nazi ideals and methods of control; Limitations: one-sided, no voice of opposition.

WJEC 考试非常强调分析原始史料。OPCVL 方法是可靠的评估「定理」：O出处（谁制作的，何时何地）+ P目的（为什么制作）+ C内容（说了什么，怎么说的）+ V价值（它对研究该时期有何揭示）+ L局限（它遗漏或歪曲了什么）。面对一幅 1936 年的纳粹宣传海报，出处：宣传部，柏林；目的：美化希特勒；内容：强壮的雅利安人形象；价值：洞察纳粹理想与控制手段；局限：一面之词，没有反对声音。

OPCVL = Origin + Purpose + Content + Value + Limitations
Always link to the historical context: ‘This source is valuable because it shows the official view of…’
Limitations can be typicality, bias, missing perspectives.

OPCVL = 出处 + 目的 + 内容 + 价值 + 局限

始终联系历史背景：「这份史料有价值，因为它展现了……的官方观点」。
局限可以是代表性不足、偏见、缺失视角。

4. The INTERPRETATION Formula | 历史解释分析公式

In the Interpretation question (e.g., Germany Depth Study), you are given two different views of an event. The INTERPRETATION formula teaches you to dissect them: Author’s Argument + Evidence Used + Context of Creation + Degree of Difference/Agreement. For example, Interpretation A might argue that the Weimar Republic was doomed from the start because of the ‘stab-in-the-back’ myth, while Interpretation B stresses the political maturity of the constitution. Your task is not just to summarise, but to explain why the historians differ, referring to their evidence and the time when they wrote.

在解释类问题（如德国深度研究）中，你会看到对同一事件两种不同的观点。解释分析公式教你解剖它们：作者论点 + 所用证据 + 创作背景 + 分歧/共识程度。例如，解释 A 可能认为魏玛共和国因「背后一刀」神话从一开始就注定失败，而解释 B 则强调宪法的政治成熟性。你的任务不仅是概括，还要通过考据证据和写作年代来解释为什么史家观点不同。

Interpretation = Author’s view + Evidence + Context + Why different?
Often the difference arises from new evidence, political beliefs, or the focus of the historian.
WJEC example: Comparison of views on the effectiveness of the League of Nations.

解释 = 作者观点 + 证据 + 背景 + 为何不同？

分歧通常源于新证据、政治信念或史家关注点的不同。
WJEC 例：比较关于国际联盟效力的不同观点。

5. The ESSAY ARGUMENT Formula (PEEL) | 论文论证公式（PEEL）

A strong history essay is built on structured paragraphs. The PEEL formula is a timeless ‘theorem’: Point – state your argument clearly; Evidence – provide specific facts, dates, names; Explain – show how the evidence proves your point; Link – connect back to the question and forward to the next point. When answering ‘How far was the Cuban Missile Crisis a victory for the USA?’, a PEEL paragraph might argue: Point – Khrushchev’s removal of missiles was a public triumph for Kennedy; Evidence – 28 October 1962, missiles withdrawn, USA pledged not to invade Cuba; Explain – The outcome boosted US prestige and contained communism; Link – However, the secret removal of US Jupiter missiles from Turkey complicates the picture of outright victory.

一篇优秀的历史论文建立于结构清晰的段落之上。PEEL 公式是历久弥新的「定理」：P观点——清晰表明你的论点；E证据——给出具体事实、日期、人名；E解释——说明证据如何证明观点；L链接——回扣问题并承上启下。在回答「古巴导弹危机在多大程度上是美国的胜利？」时，一个 PEEL 段可以这样论证：观点——赫鲁晓夫撤走导弹对肯尼迪而言是公开的胜利；证据——1962 年 10 月 28 日，导弹撤走，美国承诺不入侵古巴；解释——这一结果提升了美国威望，遏制了共产主义；链接——然而，美国秘密从土耳其撤走朱庇特导弹的事实使绝对胜利变得复杂。

PEEL = Point + Evidence + Explain + Link
For higher marks, include a ‘counter-argument’ before the Link: ‘Some historians argue…’
Use specific terminology: ‘This led to…’, ‘The consequence was…’

PEEL = 观点 + 证据 + 解释 + 链接

要拿高分，在链接前加入「反论点」：「某些史家认为……」。
使用特定术语：「这导致了……」「其后果是……」。

6. The COMPARISON Formula | 比较公式

The WJEC examination often requires you to compare two events, two sources, or two periods. The COMPARISON formula: Similarities (in cause, nature, outcome) + Differences + A Balanced Judgement of Degree. When comparing the peace settlements of 1919-20 with the post-1945 arrangements, you would find similarity in the desire to create international bodies (League of Nations vs UN), but a key difference in the treatment of defeated powers (harsh reparations vs Marshall Aid). Always use connecting phrases like ‘similarly’, ‘in contrast’, and ‘whereas’.

WJEC 考试经常要求你比较两个事件、两份史料或两个时期。比较公式：相似点（原因、性质、结果方面）+ 差异点 + 对程度的平衡评判。在比较 1919-1920 年和平方案与 1945 年后安排时，你会发现相似之处是都渴望建立国际机构（国联 vs 联合国），但关键差异在对待战败国的方式（严苛赔款 vs 马歇尔援助）。始终使用连接短语，如「相似地」「与此相对」「而」。

Compare = Similarities + Differences + Overall evaluation
Use a table to organise thoughts: causes, events, outcomes.
Example: Comparing Mussolini’s Italy with Hitler’s Germany: both used terror, but Mussolini’s control of the party was weaker.

比较 = 相似点 + 差异点 + 总体评价

用表格整理思路：原因、事件、结果。
例：比较墨索里尼的意大利与希特勒的德国：都使用恐怖手段，但墨索里尼对党的控制较弱。

7. The SIGNIFICANCE Formula | 重要性评估公式

Historians do not just recount facts; they weigh their importance. The SIGNIFICANCE formula asks five key questions: How many people were affected? How deeply were lives changed? How long did the effects last? Was it a turning point? Did it shape later events? For example, the significance of the 1929 Wall Street Crash: affected millions globally; led to deep misery and unemployment; effects lasted a decade; it was a profound turning point that discredited capitalism and enabled radical politicians.

历史学家不止是罗列事实，他们要评估事实的重要性。重要性公式提出五个关键问题：多少人受到影响？生活改变多深？影响持续多久？是否是一个转折点？它是否塑造了后来事件？例如，1929 年华尔街崩盘的重要性：影响了全球数百万人；导致深重苦难与失业；影响持续十年；它是一个深刻的转折点，使资本主义信誉扫地，让激进政客趁势崛起。

Significance = Scale + Depth + Duration + Turning Point + Legacy
Always anchor to a specific group: significance for German workers, for women, for international relations.
WJEC: Assess significance of D-Day or the dropping of the atomic bomb.

重要性 = 规模 + 深度 + 持续时间 + 转折点 + 遗产

始终锚定特定群体：对德国工人、对女性、对国际关系的重要性。
WJEC：评估诺曼底登陆或投放原子弹的重要性。

8. The JUDGEMENT Formula (WEIGHING FACTORS) | 评判公式（权衡因素）

Many exam questions ask you to ‘assess’, ‘evaluate’, or come to a judgement. The JUDGEMENT formula helps you weigh competing factors systematically: Factor A importance + Factor B importance + Interaction between factors + Conclusion on overall weighting. For a question on why the Cold War ended, you might weigh economic failure of the USSR against Reagan’s military pressure and Gorbachev’s reforms. The conclusion must show ranked judgement, e.g., ‘Gorbachev’s policies were the most decisive, but they were made possible by economic stagnation.’

许多考题要求你「评估」、「评价」或做出判断。评判公式帮助你系统权衡相互竞争的因素：因素 A 重要性 + 因素 B 重要性 + 因素间互动 + 总体权重的结论。对于冷战为何结束的问题，你要权衡苏联经济失败、里根的军事压力以及戈尔巴乔夫的改革。结论必须体现排序判断，如：「戈尔巴乔夫的政策最为决定性的，但它们之所以可能，是因为经济停滞。」

Judgement = Factor importance (with evidence) + Relative weight + Conclusion
Use language: ‘To a large extent…’, ‘While X was significant, Y proved more decisive because…’
The hallmark of a top-level answer is sustained evaluative language.

评判 = 因素重要性（附证据）+ 相对权重 + 结论

使用语言：「在很大程度上……」「虽然 X 很重要，但 Y 更具决定性，因为……」。
高分答案的标志是持续使用评估性语言。

9. The TIMELINE & PERIODISATION Formula | 时间线与分期公式

Understanding chronology is not just about memorising dates; it is about dividing the past into meaningful periods. The PERIODISATION formula: Turning Points define period boundaries + Themes create coherence within a period + Continuities bridge periods. For the USA Depth Study, 1910-1929 can be divided into Progressive Era, WWI and the Roaring Twenties. The turning point of US entry into war in 1917 marks a shift; the theme of increasing federal power runs through. Always note that periodisation is a historian’s construct, not a natural fact.

理解时间顺序不只是背日期，还在于把过去分成有意义的阶段。分期公式：转折点划定阶段边界 + 主题让阶段内部连贯 + 延续性连接不同阶段。在美国深度研究 1910-1929 中，可划分为进步时代、一战与喧嚣的二十年代。1917 年参战是划分的转折点；联邦权力增长的主题贯穿始终。要时刻记住分期是历史学家的建构，而非天然事实。

Period = Turning point + Defining theme + Temporal boundaries
Example: Cold War 1945-1991 – turning points: 1947 Truman Doctrine, 1962 Cuba, 1989 Berlin Wall.
WJEC expects you to explain why a particular date is a turning point.

分期 = 转折点 + 核心主题 + 时间边界

例：冷战 1945-1991——转折点：1947 年杜鲁门主义、1962 年古巴、1989 年柏林墙。
WJEC 期待你解释为何某日期是转折点。

10. The CROSS-REFERENCE Formula for Sources | 史料互证公式

A single source is never enough. The CROSS-REFERENCE formula is the historian’s ‘triangulation’ theorem: Source A claim + Source B confirmation/contradiction + Own knowledge validation. When analysing the success of the League of Nations in the 1920s, Source A might be a British cartoon celebrating disarmament, Source B an Italian report on border disputes, and your own knowledge of the Corfu incident. High marks come from showing how sources corroborate or challenge each other, not just describing them independently.

单独一份史料永远不够。互证公式是历史学家的「三角验证」定理：史料 A 的主张 + 史料 B 的确认/反驳 + 自身知识的印证。分析 1920 年代国际联盟的成功时，史料 A 可能是一幅庆祝裁军的英国漫画，史料 B 是一份意大利边境争端报告，再加上你对科孚岛事件的了解。高分来自展示史料如何相互印证或冲突，而不只是分别描述它们。

Cross-reference = Source A + Source B + Knowledge
Use phrases: ‘Source A supports Source B in…’, ‘However, Source C challenges this by…’, ‘My own knowledge shows that…’
Always address the weight of evidence: which source is more reliable and why?

互证 = 史料 A + 史料 B + 自身知识

使用短语：「史料 A 支持史料 B 关于……」「然而，史料 C 对此提出质疑……」「自身知识显示……」。
始终处理证据的分量：哪份史料更可靠？为什么？

11. The REVISION & RECALL Formula (ACTIVE RECALL) | 复习记忆公式（主动回忆）

Remembering the vast sweep of WJEC History is a skill in itself. The ACTIVE RECALL formula: Condense (create timeline/mind map) + Self-test (cover and recite) + Spaced repetition (review after 1 day, 3 days, 1 week) + Apply (write practice essays using formulas). Do not simply re-read notes. For the Germany Depth Study, turn key events into a clock-face timeline, then test yourself on the sequencing of the 1923 hyperinflation, Dawes Plan, and Locarno Treaties.

记住 WJEC 历史广博的内容本身就是一项技能。主动回忆公式：压缩（制作时间线/思维导图）+ 自测（遮盖后复述）+ 间隔重复（1 天、3 天、1 周后复习）+ 应用（用公式写练习论文）。不要仅仅重读笔记。对于德国深度研究，把关键事件做成钟面时间线，然后自测 1923 年恶性通货膨胀、道威斯计划和洛迦诺公约的顺序。

Recall = Summarise + Test + Space + Write
Use mnemonics: MAINS for WWI long-term causes (Militarism, Alliances, Imperialism, Nationalism, Significant individuals).
Apply the CAUSE formula to a blank sheet – generate an essay plan without looking at your book.

回忆 = 摘要 + 测试 + 间隔 + 书写

使用记忆术：如第一次世界大战长期原因的 MAIN（军国主义、联盟、帝国主义、民族主义、关键人物）。
在白纸上应用原因公式——不看课本生成论文大纲。

12. The CONSEQUENCE Formula | 后果分析公式

Every event has ripples. The CONSEQUENCE formula separates results into intentional vs unintentional outcomes, short-term vs long-term effects. Consequence = Immediate Impact + Subsequent Developments + Long-term Legacy + Unintended Outcomes. Discussing the consequences of the Treaty of Versailles: immediate – German resentment, territorial losses; subsequent – economic hardship, appeal of extremist parties; long-term – contribution to WWII; unintended – strengthening of German nationalism. In an exam, always structure your answer around this sequencing.

每个事件都有涟漪。后果公式将结果分为有意与无意、短期与长期影响。后果 = 即时影响 + 后续发展 + 长期遗产 + 非预期结果。讨论《凡尔赛条约》的后果：即时——德国怨恨、领土丢失；后续——经济困苦、极端党派吸引力；长期——促成二战；非预期——强化德国民族主义。考试中始终按这一序列组织答案。

Consequence = Immediate + Subsequent + Legacy + Unintended
Always ask: ‘For whom?’ Consequences differ for different groups (German civilians vs Allied leaders).
WJEC breadths: Consequences of the Berlin Blockade – immediate airlift success, long-term NATO formation, unintended division hardening.

后果 = 即时 + 后续 + 遗产 + 非预期

始终问：「对谁而言？」后果因群体而异（德国平民 vs 盟国领导人）。
WJEC 广度研究：柏林封锁的后果——即时空运成功，长期北约成立，非预期分裂固化。
