📚 Year 8 WJEC Media: Formula & Theory Quick Reference Guide | Year 8 WJEC 媒体：公式定理速查手册
In Media Studies, we use 'formulas' not in the mathematical sense, but as reliable frameworks, models, and patterns that help us analyse and create media texts. This quick reference guide gathers the essential concept equations, narrative formulas, and theoretical models you need for Year 8 WJEC Media. From semiotics to audience theories, every formula is broken down into its core components to make revision fast and effective.
在媒体研究课程中，我们使用的“公式”并非数学意义上的公式，而是用来分析和创作媒体文本的可靠框架、模型与模式。这份速查手册汇集了 WJEC 8年级媒体学习所必需的核心概念等式、叙事公式与理论模型。从符号学到受众理论，每一个公式都被拆解为最基本的部分，让复习变得快速又高效。
1. The Semiotic Formula | 符号学基本公式
Semiotics is the study of signs. The fundamental formula that underpins all media analysis is: Sign = Signifier + Signified. The signifier is the physical form we see or hear, while the signified is the mental concept it triggers.
符号学是研究符号的学问。支撑所有媒体分析的基本公式是：符号 = 能指 + 所指。能指是我们看到或听到的物质形式，所指则是它所触发的心理概念。
For example, a red rose (signifier) creates the mental idea of romance or passion (signified). Together they form the sign 'love'. In media texts, producers carefully choose signifiers to anchor the meanings they want audiences to decode.
例如，一朵红玫瑰（能指）会在心中建立起浪漫或激情的概念（所指）。两者共同构成“爱情”这一符号。在媒体文本中，制作者会精心选择能指，以此锚定他们希望受众解读的意义。
This formula becomes a powerful analytical tool: whenever you analyse a film poster, advert, or music video, ask yourself 'What are the signifiers, and what do they signify?'
这个公式是一个强有力的分析工具：每当你分析电影海报、广告或音乐视频时，问一问自己“能指是什么，它们又指向什么所指？”
2. Colour Connotation Formula | 色彩内涵公式
Colour works as a quick meaning-making system in media. The formula is simple: Colour + Context = Connotation. Different colours generate different emotional and symbolic responses, though context can override generic meanings.
色彩在媒体中是快速生成意义的系统。公式很简单：色彩 + 语境 = 内涵。不同颜色会产生不同的情感和象征反应，但语境可以覆盖通用的含义。
Red often connotes danger, love, or energy. Blue suggests calm, trust, or sadness. Green links to nature, envy, or health. Yellow signals warmth, happiness, or caution. In a horror poster, red becomes blood and fear; in a romance film, that same red becomes passion.
红色往往蕴含着危险、爱情或能量。蓝色暗示冷静、信任或忧伤。绿色与自然、嫉妒或健康相连。黄色发出温暖、快乐或警告的信号。在恐怖海报中，红色变为鲜血与恐惧；在一部爱情电影中，同样的红色则化为激情。
Use the colour connotation formula: list the dominant colours in the text, then decide what emotions or ideas they reinforce based on the surrounding narrative or genre.
运用色彩内涵公式：列出文本中的主色调，然后根据周围的叙事或类型判断它们强化了哪些情感或思想。
3. Camera Shot Meaning Formula | 镜头景别意义公式
Camera distance translates directly into psychological distance. The formula to remember is: Shot Size = Relationship + Information. The closer the shot, the more intimate or intense the connection; the wider the shot, the more contextual or detached the view.
摄影机与被摄体的距离直接转化为心理距离。要记住的公式是：景别 = 关系 + 信息。镜头越近，联系越亲密或紧张；镜头越远，视角越具背景性或疏离感。
An extreme close-up (ECU) magnifies details like a twitching eye, creating intensity and forcing the audience to focus on emotion. A medium close-up (MCU) is common for newsreaders, suggesting a formal yet personal address. A long shot (LS) shows the entire figure and surroundings, establishing place and isolation.
大特写（ECU）放大抽搐的眼睛等细节，制造紧张感，迫使观众聚焦于情绪。中近景（MCU）常用于新闻播报员，暗示一种正式却不失亲切的讲述方式。远景（LS）展示整个人物及其环境，交代地点与孤立状态。
When analysing, identify the dominant shot size and map it to the formula: what relationship is the director building with the character, and what information is being given or hidden?
在分析时，找出主要使用的镜头景别，并将其代入公式：导演正试图与角色建立怎样的关系，提供或隐藏了哪些信息？
4. Narrative Equilibrium Formula | 叙事平衡公式
Tzvetan Todorov's narrative theory provides a perfect formula for most mainstream stories: Equilibrium → Disruption → Recognition → Repair → New Equilibrium. This five-stage chain explains how narratives move from stability to chaos and back to a transformed stability.
茨维坦·托多罗夫的叙事理论为大多数主流故事提供了一个完美公式：平衡 → 破坏 → 认识 → 修复 → 新平衡。这个五阶段链条解释了叙事如何从稳定走向混乱，再回归一种变化后的稳定。
In a superhero film, equilibrium is the hero's ordinary life. Disruption comes with the villain's attack. The hero recognises the threat, then attempts to repair the damage. The new equilibrium often shows the world saved but the hero changed. This formula helps you map the structure of any linear narrative.
在一部超级英雄电影中，平衡是英雄的日常生活。破坏随着反派的攻击而来。英雄意识到威胁，然后尝试修复破坏。新平衡通常展现世界得救，但英雄已发生改变。这个公式能帮助你绘制出任何线性叙事的结构图。
Not all texts follow the formula rigidly, but when a text disrupts it, you can analyse why and what effect that has on the audience.
并非所有文本都严格遵循该公式，但当一个文本打破它时，你就可以分析其用意，以及这对受众产生了何种效果。
5. Character Function Formula | 角色功能公式
Vladimir Propp studied folk tales and identified a recurring set of character types, or 'functions'. The simplified formula for character analysis is: Narrative Role = Sphere of Action. Each character type performs a predictable function within the story.
弗拉基米尔·普洛普研究了民间故事，辨识出一套反复出现的角色类型，即“功能项”。角色分析的简化公式是：叙事角色 = 行动范围。每一种角色类型在故事中都执行着可以预见的功能。
The seven key types are: the Hero (seeks something), the Villain (blocks the hero), the Dispatcher (sends the hero on the quest), the Donor (gives a magical object or advice), the Helper (aids the hero), the Princess (the reward, often sought by the hero), and the False Hero (appears good but is revealed as bad).
七种关键类型为：英雄（追寻某物）、反派（阻碍英雄）、派遣者（派英雄踏上征途）、捐助者（提供宝物或建议）、帮手（协助英雄）、公主（奖赏，常为英雄所求）以及伪英雄（表面善良，最终暴露其恶）。
Applying Propp's formula allows you to sort characters not by their names but by what they do for the plot. A character can also embody more than one function.
运用普洛普的公式，你就能按角色对情节的贡献，而不是按名字来归类。一个角色也可以同时承载多种功能。
6. Uses and Gratifications Formula | 使用与满足公式
Audiences are not passive. The Uses and Gratifications model gives us a formula for why people actively choose media: Media Use = Diversion + Personal Relationships + Personal Identity + Surveillance. This equation is often remembered as the four needs.
受众并非被动的。使用与满足模型为我们提供了一个公式，来解释人们为何主动选择媒体：媒体使用 = 消遣 + 人际关系 + 个人身份认同 + 监测。这个等式通常被记为四大需求。
Diversion means escaping from routine or problems; Personal Relationships covers using media for companionship or as a social talking point; Personal Identity involves finding reinforcement for one's own values or exploring who you are; Surveillance is the need to know what is going on in the world around you.
消遣指从日常例行事务或问题中逃离；人际关系涵盖利用媒体寻求陪伴或作为社交谈资；个人身份认同涉及为自己的价值观寻找印证，或是探索自我；监测则是了解周围世界正在发生什么的需求。
For any media text you study, ask: which of these four needs does it primarily promise to satisfy for its target audience? A news app primarily offers surveillance, while a reality TV show might blend diversion, personal relationships, and personal identity.
对于你学习的任何媒体文本，都可以追问：它主要承诺满足目标受众的哪一项需求？新闻应用主要提供监测功能，而真人秀节目则可能混合了消遣、人际关系和个人身份认同。
7. Encoding and Decoding Formula | 编码与解码公式
Stuart Hall's communication model provides the formula: Message = Production (Encoding) → Text → Audience (Decoding). The producer encodes a meaning into the text, but audiences decode it based on their own backgrounds, creating three possible readings.
斯图尔特·霍尔的传播模型提供了公式：信息 = 生产（编码）→ 文本 → 受众（解码）。生产者将意义编码到文本中，但受众基于自身背景进行解码，由此产生了三种可能的解读方式。
The Dominant (or Preferred) Reading is when the audience accepts the intended message fully. The Negotiated Reading is when the audience broadly accepts the intended message but modifies some parts to fit their own experience. The Oppositional Reading is when the audience completely rejects the intended meaning because of their own social situation.
主导式（或偏好式）解读，指受众完全接受预期的信息。协商式解读，指受众大致接受预期信息，但为适应自身经验而修改了部分内容。对抗式解读，则是受众因自身的社会处境而完全拒绝该预期意义。
This formula reminds us that meaning is not fixed. The same advert can be decoded as aspirational, patronising, or irrelevant by different audiences.
这个公式提醒我们意义并非固定不变。同一则广告可以被不同受众分别解码为励志的、居高临下的或不相关的。
8. Public vs Commercial Broadcasting Formula | 公共广播与商业广播公式
Media organisations can be modelled with a simple purpose equation: Public Service Broadcaster (PSB) = Inform + Educate + Entertain, whereas Commercial Broadcaster = Revenue = Advertising + Subscriptions. This contrast explains much about content differences.
媒体机构可以用一个简单的目的等式来建模：公共服务广播 = 告知 + 教育 + 娱乐，而商业广播 = 收入 = 广告 + 订阅。这个对比在很大程度上解释了内容上的差异。
The BBC, as a PSB, must fulfil its remit to serve the public interest, producing a wide range of programmes including news, documentaries, and niche content that might not be commercially viable. Commercial channels like ITV rely on attracting large audiences to sell advertising space, meaning programme popularity is directly tied to profit.
BBC 作为公共广播机构，必须履行其公共服务职责，制作包括新闻、纪录片以及商业上可能不可行的小众节目在内的广泛内容。ITV 等商业频道则依赖于吸引大量观众来出售广告位，这意味着节目的受欢迎程度与利润直接相关。
Use this formula when comparing why one channel invests in in-depth current affairs while another broadcasts high-rating talent shows. The funding model shapes the media menu.
当比较为什么一个频道投资于深度时事节目，而另一个频道播出高收视率的才艺秀时，请运用这个公式。资金模式塑造了媒体菜单。
9. Stereotype Construction Formula | 刻板印象构建公式
Stereotypes reduce complex groups to a few exaggerated traits. The media formula for stereotyping can be written as: Stereotype = Selection + Exaggeration + Repetition. Media producers select a difference, exaggerate it, and repeat it until it seems natural.
刻板印象将复杂的群体简化为少数几个被夸大的特征。媒体刻板化的公式可以写为：刻板印象 = 挑选 + 夸张 + 重复。媒体制作者挑选出一种差异，加以夸张，并不断重复，直到它显得自然而然。
This formula is crucial for analysing representation. When you see a repeated portrayal of, say, teenagers as lazy or hoodie-wearing troublemakers, identify what has been selected from reality, how it has been exaggerated, and how often it recurs across different texts.
这个公式对于分析表现是至关重要的。当你看到青少年被反复描绘成懒惰的或穿着连帽衫的麻烦制造者时，请辨明其中哪些是从现实中挑选出来的，它们是如何被夸张的，以及在多少不同文本中反复出现。
Counter-stereotypes deliberately challenge these formulas, but they only work because audiences recognise the original formula being inverted.
反刻板印象刻意挑战这些公式，但它们之所以能奏效，正是因为受众能够识别出那些被颠覆的原始公式。
10. Composition Formula: Rule of Thirds | 构图公式：三分法
ollows geometric guidelines. The Rule of Thirds formula divides the frame into a 3×3 grid: Impact Points = Intersections of Grid Lines. Placing key elements on these intersections creates a balanced, dynamic image that feels naturally pleasing.
视觉构图遵循几何引导。三分法公式将画面划分为一个 3 × 3 的网格：视觉焦点 = 网格线的交点。将关键元素放置在这些交点上，能创造出均衡而富有动感的图像，令人感觉自然悦目。
Eyes in a close-up are typically aligned with the top horizontal line. A lone figure in a landscape is often placed on one of the vertical lines to give them 'looking room'. If the main subject is centred, ask why the rule has been broken — perhaps to create a confrontational, trapped, or formal feel.
特写镜头中的眼睛通常与上方水平线对齐。风景中的孤身人物常被置于某条垂直线上，以赋予其“视线空间”。如果主体被放在正中央，就要追问为何打破这一法则——也许是为了营造一种对峙的、受困的或者正式的感觉。
Learning the Rule of Thirds formula gives you a concrete way to discuss why a photograph or film still 'works' or creates discomfort.
学习三分法公式，能为你提供一种具体的方式，来讨论为什么某张照片或电影剧照“效果好”或反而制造了不适感。
11. Sound Formula: Diegetic vs Non-Diegetic | 声音公式：画内与画外
Sound sources are categorised using a clear boundary: Sound World = Diegetic (Inside Story) + Non-Diegetic (Outside Story). Diegetic sound is anything the characters could hear within their world; non-diegetic sound is added for the audience only.
声源按照一个清晰的界限进行分类：声音世界 = 画内音（故事内部）+ 画外音（故事外部）。画内音是角色在他们所在的世界里可以听到的任何声音；画外音则是仅为观众添加的。
Dialogue, a slamming door, and music from a radio in the scene are diegetic. A dramatic orchestral score, a voiceover narrator, and sound effects added to enhance a punch are non-diegetic. The real magic happens in the formula's combination: a non-diegetic heartbeat over a silent scene creates tension, while suddenly cutting all non-diegetic sound can shock the audience into a character's raw reality.
对话、摔门声和场景中收音机播放的音乐都是画内音。戏剧性的管弦乐配乐、旁白叙述者以及为强化拳击效果而添加的音效则是画外音。真正的魔力发生在这个公式的组合上：在一个寂静的场景上叠加非画内的心跳声会制造紧张感，而骤然切断所有画外音则会使观众猛然坠入角色未加修饰的现实世界。
In your analysis, always identify which sounds belong to which category and what emotional effect the mix creates.
在你的分析中，始终要辨明哪些声音属于哪种类别，以及这种混合创造了怎样的情绪效果。
12. Genre Hybridity Formula | 类型混合公式
Genre is governed by a mixing formula: Hybrid Genre = Genre A's Conventions + Genre B's Conventions. Media producers blend familiar ingredients to create fresh texts that still feel recognisable and marketable.
类型由一个混合公式所支配：混合类型 = A类型的惯例 + B类型的惯例。媒体制作者混合熟悉的元素，创造出既令人感觉新鲜，又依然便于识别和市场推广的文本。
'Romantic comedy' blends the emotional hurdles and happy endings of romance with the awkward situations and humour of comedy. 'Science fiction horror' merges futuristic settings and technology with suspense, gore, and fear. The formula works because audiences have a mental catalogue of genre conventions. When they see them combined, the meaning shifts and appeals to wider audience segments.
“浪漫喜剧”将爱情故事中的情感波折与美满结局，和喜剧中的窘迫情境与幽默相融合。“科幻恐怖片”则将未来主义设定与科技，和悬疑、血腥与恐惧混为一体。这个公式之所以有效，是因为观众脑中都存有一份类型惯例的目录。当他们看到这些惯例被合并时，意义就会转变，并吸引更广泛的受众群体。
To analyse a hybrid, first list the conventions of each parent genre, then explain what new meanings are produced by their collision.
要分析一个混合类型，首先要列出每个母类型的惯例，然后解释它们的碰撞产生了哪些新的意义。
