📚 IGCSE Cambridge Media Studies Formula & Theory Quick Reference | IGCSE Cambridge 媒体研究公式定理速查手册
In IGCSE Cambridge Media Studies, you do not learn equations like F = ma, but you do need analytical formulas that can be repeated across texts: media language, representation, audience and institution. This quick reference collects the models, theories and terminology most useful for Papers 1 and 2, from semiotics and narrative to camera work and exam structure.
在 IGCSE Cambridge 媒体研究中，你虽然不会学习 F = ma 这样的物理公式，但需要掌握可反复用于各类文本的分析公式：媒体语言、表征、受众与机构。这份速查手册汇总了 Paper 1 和 Paper 2 最有用的模型、理论与术语，涵盖符号学、叙事、镜头语言以及答题结构。
1. Media Text Analysis Formula | 媒体文本分析公式
Media text = Media language × Representation × Audience × Institution
This formula is the core of Cambridge Media Studies. Every media text can be analysed by asking how it uses codes, what it represents, who it addresses and which organisation produced it.
这个公式是剑桥媒体研究的核心。任何媒体文本都可以通过四个问题来分析：它使用了哪些代码、它再现了什么、它面向谁、以及由哪个机构制作。
- Media language: codes and conventions such as camera, sound, editing, mise-en-scène. | 媒体语言：镜头、声音、剪辑、场面调度等代码与惯例。
- Representation: how people, places and ideas are constructed. | 表征：人物、地点和观念如何被建构。
- Audience: target group and how the text appeals to them. | 受众：目标群体及文本如何吸引他们。
- Institution: producer, ownership, funding and regulation. | 机构：制作方、所有权、资金来源与监管。
In exam answers, apply the formula in any order, but try to link the four areas rather than treating them as separate boxes. For example, a TV drama’s low-key lighting is a media language choice that constructs a fearful representation and positions the audience to feel suspense for a commercial broadcaster.
在考试答题中，你可以按任意顺序应用这个公式，但尽量把四个领域联系起来，而不是把它们当作孤立的条目。例如，电视剧中的低调布光是一种媒体语言选择，它建构了恐惧的表征，并让观众为商业广播公司感到悬疑。
2. Semiotics: Signifier and Signified | 符号学：能指与所指
Sign = Signifier + Signified
A sign is made of a physical form, the signifier, and the mental concept it creates, the signified. For example, a gold medal is a signifier: metal on a ribbon, and its signified could be victory, achievement or national pride.
符号由物质形式（能指）和它引发的心理概念（所指）组成。例如，金牌是能指：缎带上的金属；它的所指可能是胜利、成就或国家荣誉。
Roland Barthes adds a second layer: denotation is the literal meaning, while connotation is the cultural association. Producers often anchor preferred meanings through captions, music or editing to limit alternative readings.
罗兰·巴特增加了第二层：外延是字面意义，内涵是文化联想。制作方常通过字幕、音乐或剪辑来锚定优先意义，以限制其他解读。
| Sign | Signifier | Signified | Connotation |
|---|---|---|---|
| Red rose | red flower | romance or politics | love, passion, labour movement |
| Crown | ornamental headpiece | monarchy or authority | power, tradition, inequality |
In Media Studies, identifying signs is not enough: you must explain how signifier and signified work together to create ideology or myth.
在媒体研究中，识别符号是不够的：你必须解释能指和所指如何共同作用，以创造意识形态或神话。
3. Narrative Theory: Todorov’s Equilibrium Formula | 叙事理论：托多罗夫平衡公式
Equilibrium → Disruption → Recognition → Attempt to repair → New equilibrium
Todorov argues that narratives begin in a stable world, which is disrupted, then recognised, repaired, and finally closed by a new equilibrium that is never identical to the first.
托多罗夫认为，叙事从一个稳定的世界开始，这个世界被打破，随后被识别、修复，最后以一个新的平衡结束，但这个新平衡永远不会与最初的完全相同。
- Equilibrium: everyday life is normal and balanced. | 平衡：日常生活正常且平衡。
- Disruption: an event changes the situation. | 打破：一个事件改变了局面。
- Recognition: characters realise the disruption. | 识别：人物意识到破坏。
- Attempt to repair: characters act to solve the problem. | 修复尝试：人物采取行动解决问题。
- New equilibrium: a different stability is reached. | 新平衡：达到一种不同的稳定。
This model works well for film trailers, news stories and advertisements, where disruption is often introduced early to capture attention. In an exam, you can map a text’s plot onto the formula to prove it follows or challenges conventional narrative structure.
这个模型适用于电影预告片、新闻报道和广告，因为这些文本通常早期就引入破坏以吸引注意力。在考试中，你可以将文本情节映射到公式上，证明它遵循或挑战了传统叙事结构。
4. Character Functions: Propp’s Seven Spheres | 人物功能：普洛普七种行动圈
Character = Function (not personality)
Vladimir Propp studied folk tales and found that characters exist to perform narrative functions, not simply to show personality. Cambridge candidates often apply these seven spheres to film, advertising and news narratives.
弗拉基米尔·普洛普研究民间故事后发现，人物存在是为了执行叙事功能，而不仅仅是为了展示个性。剑桥考生常将这七种行动圈应用于电影、广告和新闻叙事。
- Villain: opposes the hero. | 反派：与英雄作对。
- Donor: gives the hero a magical object or knowledge. | 赠予者：给英雄魔法物品或知识。
- Helper: supports the hero. | 帮助者：支持英雄。
- Princess: sought by the hero; often the reward. | 公主：英雄寻找的对象；通常是奖励。
- Dispatcher: sends the hero on the quest. | 派遣者：派英雄去执行任务。
- Hero: restores equilibrium and wins the reward. | 英雄：恢复平衡并获得奖励。
- False hero: appears good but is ultimately exposed. | 假英雄：看似善良，最终被揭穿。
Modern media often combine functions: a protagonist may be hero and dispatcher, or a brand may act as donor in an advertisement. Use the formula to discuss how roles are assigned and what values this promotes.
现代媒体常常合并功能：主角可能既是英雄又是派遣者，或者品牌在广告中充当赠予者。使用该公式讨论角色如何分配，以及这宣扬了什么价值观。
5. Binary Oppositions: Lévi-Strauss | 二元对立：列维-斯特劳斯
Meaning = Opposition A vs Opposition B
Claude Lévi-Strauss argues that narratives are structured through pairs of opposites. Conflict between opposites drives interest and encodes ideology, because one side is usually privileged as normal or good.
克洛德·列维-斯特劳斯认为，叙事通过成对的对立来结构。对立之间的冲突驱动兴趣并编码意识形态，因为其中一方通常被特权化为正常或善。
- Good vs evil | 善与恶
- Past vs future | 过去与未来
- Nature vs technology | 自然与科技
- Urban vs rural | 城市与乡村
- Young vs old | 年轻与年老
- East vs West | 东方与西方
In an exam, identify a binary opposition, then explain which side is preferred and how the text encourages that preference. For example, a crime drama may oppose police as order and criminals as chaos, reinforcing the message that law enforcement protects society.
在考试中，识别一个二元对立，然后解释哪一方被偏好，以及文本如何鼓励这种偏好。例如，一部犯罪剧可能将警察作为秩序、罪犯作为混乱对立起来，强化执法保护社会的讯息。
6. Representation Formula | 表征公式
Representation = Selection + Construction + Mediation
Media does not mirror reality; it selects elements, constructs a version and mediates it through codes. This process shapes audience beliefs about social groups, places and issues.
媒体并不是镜像现实；它选择元素、建构一个版本并通过代码进行中介。这个过程塑造了观众对社会群体、地点和议题的信念。
Stereotype = Simplified trait × Repetition × Social power
A stereotype reduces a group to a few exaggerated traits, repeats them across texts and often reinforces the power of dominant groups. Studying stereotypes means asking whose interests they serve.
刻板印象将一个群体简化为少数夸张的特征，并在不同文本中重复这些特征，往往强化了主流群体的权力。研究刻板印象意味着追问它们服务于谁的利益。
Encoding → Preferred reading / Negotiated reading / Oppositional reading
Stuart Hall’s encoding/decoding model says producers encode meanings and audiences can decode them in three ways: accept the preferred meaning, partially accept it, or reject it from an alternative perspective.
斯图亚特·霍尔的编码/解码模型指出，制作者编码意义，而受众可以以三种方式解码：接受优先意义、部分接受，或从另一种视角拒绝它。
7. Audience Theories: Uses and Gratifications | 受众理论：使用与满足
Media use = Diversion + Personal relationships + Personal identity + Surveillance
Blumler and Katz argue that audiences actively select media to satisfy needs. This opposes the hypodermic needle idea that media simply injects messages into passive viewers.
布鲁姆勒和卡茨认为，受众主动选择媒体来满足需求。这与皮下注射针模式相反，后者认为媒体只是将讯息注入被动的观众。
| Need | Explanation | Example |
|---|---|---|
| Diversion | escape from routine or problems | watching sitcoms to relax |
| Personal relationships | companionship with media figures or social chat | following influencers |
| Personal identity | comparing self with values and lifestyles | reading teen magazines |
| Surveillance | gathering information about the world | checking news apps |
In answers, avoid saying ‘everyone uses media for escape’. Instead, use the formula to weigh up different possible gratifications for different audiences.
在答题时，不要说“每个人都用媒体来逃避”。相反，要使用这个公式来权衡不同受众可能获得的不同满足。
8. Media Language: Technical Codes | 媒体语言：技术代码
Technical code = Camera + Sound + Editing + Mise-en-scène
Technical codes are the building blocks of media language. You must use precise terminology in exam answers to show analysis rather than description.
技术代码是媒体语言的构成模块。你必须在考试答案中使用准确的术语，以体现分析而不是描述。
| Code | Elements | Code | 要素 |
|---|---|---|
| Camera | shot size, angle, movement | 镜头 | 景别、角度、运动 |
| Sound | diegetic, non-diegetic, dialogue, music, effects | 声音 | 剧情内、剧情外、对白、音乐、音效 |
| Editing | cutting, pace, transitions, continuity | 剪辑 | 剪切、节奏、转场、连续性 |
| Mise-en-scène | 更多咨询请联系16621398022（同微信）
