📚 Year 7 OCR Media Studies: Formula & Theorem Quick Reference | Year 7 OCR 媒体：公式定理速查手册
Welcome to your quick reference guide for Year 7 OCR Media Studies. Just like in science or maths, media has its own ‘formulas’ and ‘theorems’ that help us understand how TV shows, films, advertisements and social media content are made and why they affect us. These are not number equations but thinking frameworks that decode everything from camera angles to character types. Keep this handbook close as you analyse media texts and build your own creative projects.
欢迎来到你的 Year 7 OCR 媒体研究速查手册。就像科学或数学一样，媒体也有自己的“公式”和“定理”，帮助我们理解电视节目、电影、广告和社交媒体内容是如何制作的，以及它们为什么会影响我们。这些不是数字方程式，而是解码一切的思维框架，从摄像机角度到角色类型。当你分析媒体文本并构建自己的创意项目时，请将这本手册放在手边。
1. The Uses and Gratifications Formula | 使用与满足公式
Blumler and Katz (1974) suggested that audiences actively choose media to satisfy specific needs. This formula breaks down four main reasons why we engage with media.
Blumler 和 Katz（1974）提出，受众主动选择媒体来满足特定需求。这个公式分解了我们接触媒体的四个主要原因。
Personal Identity: Media helps us reinforce our own values and understand ourselves. For example, watching a vlogger who shares your hobby makes you feel part of a community.
个人身份认同：媒体帮助我们强化自身价值观并理解自我。例如，观看一个与你共享爱好的视频博主会让你感觉自己是社群的一部分。
Information: We use media to learn about the world, from news bulletins to documentary films. A weather app is a classic tool for information seeking.
信息获取：我们使用媒体来了解世界，从新闻公告到纪录片。天气应用就是寻求信息的经典工具。
Entertainment: This covers enjoyment, relaxation and escapism. Binge watching a comedy series or playing a video game delivers fun and emotional release.
娱乐消遣：这涵盖了享受、放松和逃避现实。连续观看一部喜剧系列或玩电子游戏能带来乐趣和情感释放。
Social Interaction: Media can connect us with others. Discussing the latest episode of a drama on group chats or bonding with family over a film fulfills this need.
社交互动：媒体可以将我们与他人联系起来。在群聊中讨论最新一集剧情或与家人一起看电影都满足了这一需求。
2. Reception Theory: Encoding and Decoding | 接收理论：编码与解码
Stuart Hall’s theory states that a media producer encodes a message, but the audience can decode it in three different ways. The meaning is not fixed.
Stuart Hall 的理论指出，媒体制作者将信息编码，但受众可以用三种不同的方式解码。意义并非固定。
Dominant / Preferred Reading: The audience accepts the intended message fully. If an advert shows a runner winning with a certain drink, you accept that the drink helps success.
主导/偏好解读：受众完全接受预期的信息。如果广告展示一名跑者喝了某种饮料后获胜，你接受了该饮料有助于成功的观念。
Negotiated Reading: You partially agree but modify the message to fit your own experience. You might think the drink tastes good but doubt it makes you a champion.
协商解读：你部分同意但根据自身经验修改信息。你可能认为该饮料好喝，但怀疑它能否让你成为冠军。
Oppositional Reading: You completely reject the intended meaning because of your own beliefs. You might recognise that the runner’s victory is purely due to training and find the advert misleading.
对抗解读：你因自身信念而完全拒绝预期意义。你可能认识到跑者的胜利纯粹来自训练，并觉得广告具有误导性。
3. Propp’s Character Archetype Theorem | 普罗普角色原型定理
Vladimir Propp analysed hundreds of folk tales and identified seven recurring character types. This theorem still applies to modern films, books and games.
Vladimir Propp 分析了数百个民间故事，识别出七种反复出现的角色类型。这个定理仍然适用于现代电影、书籍和游戏。
- The Hero: The protagonist who goes on a quest. (Chinese: 英雄：踏上征程的主人公。)
- The Villain: The antagonist who opposes the hero. (中文：反派：与英雄作对的反面角色。)
- The Dispatcher: The character who sends the hero on the mission. (中文：派遣者：派遣英雄执行任务的角色。)
- The Donor: Gives the hero a magical object or advice. (中文：捐赠者：给予英雄魔法物品或建议。)
- The Helper: Assists the hero throughout the journey. (中文：帮手：在旅程中协助英雄。)
- The Princess: A reward for the hero, often needing rescue. (中文：公主：英雄的奖赏，常需要被拯救。)
- The False Hero: Pretends to be good but is revealed as deceitful. (中文：伪英雄：假装善良但最终暴露欺骗性。)
4. Todorov’s Narrative Equilibrium Model | 托多罗夫叙事平衡模型
Tzvetan Todorov proposed that most stories follow a simple five-stage structure moving from balance to chaos and back to a new balance. It works like a story equation.
Tzvetan Todorov 提出，大多数故事遵循一个简单的五阶段结构，从平衡到混乱再回到新的平衡。它就像一个故事方程式。
Equilibrium → Disruption → Recognition → Attempt to Repair → New Equilibrium
平衡 → 破坏 → 意识 → 尝试修复 → 新平衡
Equilibrium: The normal, peaceful start. (Chinese: 平衡：常态、平静的开端。)
Disruption: An event disrupts the balance. (中文：破坏：一个事件打破了平衡。)
Recognition: Characters realise the disruption. (中文：意识：角色意识到破坏。)
Attempt to Repair: The hero tries to fix the problem. (中文：尝试修复：英雄试图解决问题。)
New Equilibrium: Order is restored but the world is changed. (中文：新平衡：秩序恢复但世界已改变。)
5. Barthes’ Enigma and Action Codes | 巴特的谜团与行动符码
Roland Barthes argued that narratives are driven by two key codes that hook the audience and move the plot forward.
Roland Barthes 认为，叙事由两种关键符码驱动，它们吸引观众并推动情节发展。
Enigma Code: This creates mysteries and questions that the audience wants answered. A film might open with a locked door, a strange sound or a hidden letter. We keep watching to solve the puzzle.
谜团符码：这创造了观众想要答案的谜团和问题。一部电影可能以一扇锁着的门、一个奇怪的声音或一封隐藏的信件开场。我们继续观看以解开谜题。
Action Code: Any action that suggests a further action will follow, building tension. A character picking up a knife or a car speeding away signals that a significant event is about to happen.
行动符码：任何暗示后续行动会增加紧张感的动作。一个角色拿起刀或一辆车飞驰而去，都预示着即将发生重要事件。
6. Semiotics: Sign, Signifier, Signified | 符号学：符号、能指、所指
Ferdinand de Saussure’s semiotics is the study of signs. Every media sign is made of two parts that together create meaning.
Ferdinand de Saussure 的符号学是对符号的研究。每个媒体符号由两部分组成，共同创造意义。
| Term / 术语 | Definition / 定义 | Example / 例子 |
|---|---|---|
| Signifier / 能指 | The physical form: word, image, sound. / 物理形式：词、图像、声音。 | A red rose on a card. / 卡片上的一朵红玫瑰。 |
| Signified / 所指 | The mental concept it evokes. / 它唤起的心智概念。 | Love, romance, passion. / 爱情，浪漫，激情。 |
| Sign / 符号 | The combined meaning. / 组合而成的整体意义。 | The rose symbolises love. / 玫瑰象征着爱。 |
7. Mise-en-scène Elements | 场面调度元素
Mise-en-scène is French for ‘placed in the scene’ and refers to everything visible in a frame. This visual formula helps directors communicate mood and character.
Mise-en-scène 是法语，意为“置于场景中”，指的是帧中可见的一切。这个视觉公式帮助导演传达情绪和角色。
Setting: The location and backdrop, e.g. a spooky forest or a shiny lab. (Chinese: 场景：地点和背景，例如阴森的森林或闪亮的实验室。)
Lighting: High-key lighting creates a bright, happy mood; low-key lighting with shadows builds suspense. (中文: 灯光：高调光营造明亮、快乐的氛围；带阴影的低调光营造悬念。)
Costume & Make-up: Tells us about a character’s personality, era or status. A lab coat suggests a scientist. (中文: 服装与化妆：告诉我们角色的个性、时代或地位。白大褂暗示科学家。)
Props: Objects that actors interact with, like a magic wand or a detective’s magnifying glass. (中文: 道具：演员使用的物品，如魔杖或侦探的放大镜。)
Performance & Movement: Facial expressions and body language convey emotion. (中文: 表演与动作：面部表情和肢体语言传达情绪。)
8. Camera Shot Size Theorem | 镜头景别定理
The distance between the camera and the subject determines how we connect with a character. Each shot size follows a simple rule of engagement.
摄像机与被摄体之间的距离决定我们与角色的连接方式。每种景别遵循简单的参与规则。
| Shot / 景别 | Effect / 效果 |
|---|---|
| Extreme Long Shot (ELS) / 大远景 | Shows environment; character is tiny. Used to establish setting. / 展示环境；角色很小。用于交代场景。 |
| Long Shot (LS) / 远景 | Full body visible. Shows action and setting. / 全身可见。展示动作和场景。 |
| Medium Shot (MS) / 中景 | Waist up. Common for dialogue; connects us to character while showing some background. / 腰部以上。常用于对话；在展示背景同时连接角色。 |
| Close-up (CU) / 特写 | Face fills frame. Reveals emotions and reactions. / 面部充满画面。揭示情感和反应。 |
| Extreme Close-up (ECU) / 大特写 | Focuses on a detail (eyes, hand). Creates intensity or symbolism. / 聚焦细节（眼睛、手）。带来强度或象征意义。 |
9. Audience Classification: Demographic Profiling | 受众分类：人口统计画像
Media producers use demographic formulas to categorise their audience. The most common UK system is the NRS social grades, based on occupation and income.
媒体制作者使用人口统计公式来对受众进行分类。英国最常见的系统是基于职业和收入的 NRS 社会等级。
| Grade / 等级 | Social Class / 社会阶层 | Typical Occupation / 典型职业 |
|---|---|---|
| A | Upper Middle Class / 上层中产 | Doctor, lawyer, senior manager / 医生、律师、高级经理 |
| B | Middle Class / 中产 | Teacher, nurse, junior manager / 教师、护士、初级经理 |
| C1 | Lower Middle Class / 下层中产 | Office worker, supervisor / 办公室职员、主管 |
| C2 | Skilled Working Class / 熟练工人阶级 | Electrician, plumber / 电工、水管工 |
| D | Working Class / 工人阶级 | Factory worker, cleaner / 工厂工人、清洁工 |
| E | Subsistence / 勉强维生 | Unemployed, pensioner / 失业者、养老金领取者 |
Besides social grade, producers also segment by age, gender, lifestyle and media habits to target adverts and shows effectively.
除了社会等级，制作者还根据年龄、性别、生活方式和媒体习惯进行细分，以有效投放广告和节目。
10. Stereotypes and Countertypes | 刻板印象与反刻板印象
Representation in media often relies on shortcuts. A stereotype is a simplified, often exaggerated image of a group. A countertype challenges these expectations.
媒体中的再现常依赖捷径。刻板印象是对某一群体的简化、常夸张的形象。反刻板印象则挑战这些预期。
Stereotype Formula: Repeated traits associated with a group, e.g. teenagers portrayed as moody and rebellious, or scientists as geeky loners in glasses.
刻板印象公式：与一个群体相关联的重复特质，例如青少年被描绘为喜怒无常和叛逆的，或科学家被描绘为戴眼镜的孤僻怪才。
Countertype Formula: The opposite of a stereotype; it surprises the audience and encourages thinking. A strong, logical female hero in action films or a sensitive, caring male nurse breaks traditional boxes.
反刻板印象公式：是刻板印象的对立面；它让观众惊讶并鼓励思考。动作片中的坚强、有逻辑的女性英雄，或一位敏感、体贴的男护士打破了传统框框。
When analysing media, ask yourself: Is this a fair representation? Who created it and why?
分析媒体时，问自己：这是一个公平的再现吗？谁创造了它，为什么？
11. Media Language: Denotation and Connotation | 媒体语言：外延与内涵
Roland Barthes also taught us to read images on two levels. This formula helps you decode deeper meanings in posters, adverts and photos.
Roland Barthes 还教我们从两个层面解读图像。这个公式帮助你解码海报、广告和照片中的深层意义。
Denotation: What you literally see. For a movie poster of a superhero standing on a rooftop at night, denotation is simply: a person in cape on a building.
外延：你实际看到的内容。对于一张超级英雄夜晚站在屋顶上的电影海报，外延仅仅是：一个穿着斗篷的人在大厦上。
Connotation: The associated meanings and feelings. The same image connotes mystery, power, isolation and vigilante justice. These come from cultural understanding.
内涵：相关联的意义和感受。同一幅图像内涵着神秘、权力、孤独和义警正义。这些来自文化理解。
12. Binary Oppositions in Media | 媒体中的二元对立
Claude Lévi-Strauss believed that narratives are built on conflicts between opposing forces. This theorem of binary oppositions drives drama.
Claude Lévi-Strauss 认为叙事是建立在相互冲突的力量对立之上的。这个二元对立定理驱动着戏剧。
| Opposition Pair / 对立对 | Media Example / 媒体例子 |
|---|---|
| Good vs Evil / 善与恶 | Harry Potter vs Voldemort / 哈利波特与伏地魔 |
| Young vs Old / 年轻与年老 | The rebellious teen versus the strict parent in sitcoms / 情景喜剧中叛逆青少年与严厉家长 |
| Man vs Nature / 人与大自然 | Survival films like The Day After Tomorrow / 生存电影如《后天》 |
| Rich vs Poor / 富与穷 | The elegant upper class versus the struggling underclass in period dramas / 古装剧中优雅的上层阶级与挣扎的下层阶级 |
| Justice vs Injustice / 正义与不公 | Heroic lawyer versus a corrupt system / 英雄律师与腐败体系 |
These opposites simplify conflict and help audiences quickly grasp the moral universe of a story.
这些对立简化了冲突，帮助受众快速把握故事的道德宇宙。
