📚 Year 7 CCEA Sociology: Formulas & Theorems Quick Reference | 7年级 CCEA 社会学：公式定理速查手册
Sociology may not have mathematical formulas in the same way Physics does, but it is built on powerful ‘formulas’ and ‘theorems’ – recurring patterns that explain how society works. This quick reference guide gathers the essential ideas, connections and principles you will meet in Year 7 CCEA Sociology. Each entry is presented as a simple equation or rule to help you remember the building blocks of sociological thinking.
社会学或许不像物理学那样拥有数学公式，但它建立在一系列强大的“公式”和“定理”之上——这些反复出现的模式解释了社会的运作方式。这份速查手册汇集了你在7年级 CCEA 社会学课程中会遇到的核心思想、联系和原理。每个条目都以简单的等式或规则呈现，帮助你记住社会学思维的基石。
1. The Core Formula of Sociology | 社会学的核心公式
Sociology = How individuals shape society + How society shapes individuals
社会学 = 个体如何塑造社会 + 社会如何塑造个体
Every topic in sociology comes back to this two‑way relationship. We study families, schools, peer groups and media to see how they influence our behaviour, and also how our actions can change those institutions.
社会学的每个主题都回归到这种双向关系。我们研究家庭、学校、同伴群体和媒体，看它们如何影响我们的行为，同时我们的行动又如何改变这些制度。
2. Socialisation Formula | 社会化公式
Socialisation = Primary Socialisation (family) + Secondary Socialisation (school, peers, media, religion, workplace)
社会化 = 初级社会化（家庭）+ 次级社会化（学校、同伴、媒体、宗教、工作场所）
Primary socialisation happens in the first years of life, where we learn language, basic norms and values from our family. Secondary socialisation continues throughout life as we encounter new agents that teach us the rules of wider society.
初级社会化发生在我们生命的最初几年，我们从家庭那里学习语言、基本规范和价值观。次级社会化则贯穿一生，当我们接触新的社会化机构时，它们会教会我们更广泛的社会规则。
3. The Role Theorem | 角色定理
Every social role comes with a set of expected behaviours. Role conflict occurs when two or more roles demand opposing actions.
每一个社会角色都伴有一整套期待的行为。当两个或以上的角色要求相互对立的行为时，就会发生角色冲突。
For example, being a student means you are expected to do homework and listen in class. If you also have a role as a friend who wants to play outside, you might experience role conflict. Understanding this theorem helps explain tensions in everyday life.
例如，作为学生，你被期望完成作业并在课堂上认真听讲。如果你同时还有一个想要出去玩的朋友角色，你就可能会经历角色冲突。理解这一定理有助于解释日常生活中的紧张关系。
4. Culture Equation | 文化等式
Culture = Material culture (objects) + Non‑material culture (beliefs, values, language, norms)
文化 = 物质文化（物品）+ 非物质文化（信仰、价值观、语言、规范）
When sociologists study a society, they look at tangible things like clothes, food and technology, as well as intangible things like customs, traditions and moral beliefs. Both sides are equally important.
社会学家研究一个社会时，既会观察衣服、食物和科技等有形的东西，也会关注风俗、传统和道德信仰等无形的东西。这两方面同等重要。
5. The Norms ↔ Values Rule | 规范与价值观相互作用规则
Norms are the everyday rules that reflect deeper values. Change the value → the norm follows.
规范是反映深层价值观的日常规则。价值观改变 → 规范随之改变。
If a society values equality, its norms might include equal sharing of household chores. If the value shifts towards individualism, norms around family meals may change. This rule connects abstract beliefs to concrete behaviour.
如果一个社会重视平等，其规范可能包括平等分担家务。如果价值观转向个人主义，围绕家庭聚餐的规范可能随之改变。这条规则把抽象的信仰与具体的行为联系了起来。
6. The Family Function Theorem | 家庭功能定理
Family functions = (emotional support + economic provision + socialisation of children + regulation of behaviour) for individuals and society.
家庭功能 = （情感支持 + 经济供养 + 子女社会化 + 行为调控），服务于个体与社会。
According to functionalists, the family exists because it performs these essential tasks. Even as family forms diversify, the core functions tend to persist in different ways.
根据功能主义者的观点，家庭之所以存在，是因为它执行着这些基本任务。即使家庭形式多样化，核心功能也往往以不同方式持续存在。
7. The Social Stratification ‘Layers’ Theorem | 社会分层“层级”定理
Society is divided into layers (strata) based on factors such as wealth, occupation, education and power. Life chances are distributed unequally across these layers.
社会根据财富、职业、教育和权力等因素被划分为不同层级（阶层）。生活机会在这些层级之间分布不均。
Social stratification is like a ladder: the higher the rung, the better the access to healthcare, good housing and quality education. Sociologists study how open or closed this ladder is in different societies.
社会分层就像一架梯子：所处层级越高，获得医疗保健、良好住房和优质教育的机会就越多。社会学家研究在不同社会中这架梯子的开放或封闭程度。
8. The Education Function Formula | 教育功能公式
Education = Academic curriculum + Hidden curriculum (teaching obedience, punctuality, competition, cooperation)
教育 = 显性课程 + 隐性课程（灌输服从、守时、竞争、合作）
Schools do more than teach subjects. The hidden curriculum includes the unwritten lessons about how to behave in a crowd, follow instructions and accept hierarchy. This formula helps explain how education links to the world of work.
学校所做的不仅仅是教授学科知识。隐性课程包括那些不成文的课程，教导人们如何在群体中行为、遵循指令和接受等级制度。这个公式有助于解释教育如何与工作世界相联系。
9. The Peer Group ‘Mirror’ Principle | 同伴群体“镜子”原理
Peer influence = Imitation + Social approval + Shared identity
同伴影响 = 模仿 + 社会认同 + 共享身份
Young people often mirror the language, fashion and attitudes of their friendship group because they seek belonging. This principle shows that secondary socialisation can sometimes clash with values learned at home.
年轻人常常模仿其友谊群体的语言、时尚和态度，因为他们寻求归属感。这一原理表明，次级社会化有时会与家中习得的价值观发生冲突。
10. The Media Effects Equation | 媒体效应方程
Media effect = (Message × Frequency) / Critical thinking
媒体效应 = （信息 × 频率）/ 批判性思维
The more often we see a message, the stronger its potential influence – unless we actively question it. This simple equation reminds us that media literacy (the ability to evaluate media content) reduces the power of one‑sided messages.
我们看到一条信息的频率越高，其潜在影响力就越大——除非我们主动对其进行质疑。这个简单的等式提醒我们，媒介素养（评估媒体内容的能力）会削弱单方面信息的影响力。
11. Primary vs Secondary Data Rule | 一手数据与二手数据规则
Primary data = collected by the researcher for the specific study (e.g., questionnaires, interviews). Secondary data = already exists, collected by someone else (e.g., official statistics, diaries).
一手数据 = 研究者为特定研究亲自收集的数据（如问卷、访谈）。二手数据 = 已经存在、由他人收集的数据（如官方统计、日记）。
Knowing the difference is essential for evaluating research. Primary data fits the purpose exactly but takes time; secondary data is quick to access but may not answer the exact question. Both are used in sociological investigations.
了解两者区别对评估研究至关重要。一手数据完全契合研究目的但费时；二手数据获取快捷但可能无法精确回答问题。两者都会在社会学调查中使用。
12. The Research Process Theorem | 研究过程定理
Valid sociological research follows: Research question → Hypothesis → Method selection → Data collection → Analysis → Conclusion → Evaluation
有效的社会学研究遵循：研究问题 → 假设 → 方法选择 → 数据收集 → 分析 → 结论 → 评估
This sequence ensures that findings are based on evidence, not just opinion. Even at Year 7 level, understanding this chain helps you structure simple investigations and spot weaknesses in arguments you hear or read.
这一顺序确保研究结果建立在证据而非纯粹观点之上。即使在7年级阶段，理解这个链条也能帮助你组织简单的调查，并识别你在听到或读到的论点中的薄弱之处。
