Core EE Structure 规划 | Core EE Structure Planning

## IB EE 结构 选题 RQ 评分标准 写作框架 高分 The Extended Essay (EE) is one of the three core components of the IB Diploma Programme, alongside Theory of Knowledge (TOK) and Creativity, Activity, Service (CAS). It is a 4000-word independent research paper that gives students the opportunity to investigate a topic of personal interest within one of the six IB subject groups. 拓展论文是IB文凭课程三大核心组成部分之一，要求学生完成一篇4000词的独立研究论文，深入探究个人感兴趣的学术话题。 For many IB students, the EE is both the most challenging and the most rewarding part of the diploma. It teaches skills that are directly transferable to university: formulating a research question, conducting a literature review, structuring an academic argument, and referencing sources correctly. 对很多IB学生来说，EE既是最具挑战性也是最有收获的部分。它培养的技能——提出研究问题、进行文献综述、构建学术论证、正确引用来源——直接衔接大学学习。

一 什么是IB Extended Essay What is the IB Extended Essay

The Extended Essay is not just a long essay. It is a formal piece of academic writing that demonstrates your ability to independently research and write about a focused topic. The word limit is 4000 words, which includes the introduction, body, and conclusion but excludes the abstract, table of contents, bibliography, and appendices. EE不是一篇普通的长作文，它是一篇正式的学术论文，展示你独立研究和写作的能力。字数上限为4000词，包括引言、正文和结论，但不包括摘要、目录、参考文献和附录。 The EE is assessed externally by IB examiners and is graded on a scale from A (highest) to E (lowest). Combined with your TOK grade, it contributes up to 3 bonus points toward your diploma total. A strong EE can be the difference between a pass and a fail, or between getting your diploma and missing out. EE由IB考官外部评估，评分从A到E。与TOK成绩结合后，最多可为总分增加3个奖励分。一篇出色的EE可能决定你是否能拿到文凭。

二 EE的标准结构 Standard EE Structure

While the exact structure varies slightly by subject, every Extended Essay should include the following components. A well-organized structure is one of the easiest ways to impress examiners before they even read a single word of your argument. 虽然具体结构因学科略有不同，但每篇EE都应包含以下组成部分。清晰的组织结构是最容易给考官留下好印象的方式之一。 1. Title Page 封面
Your research question, subject, and word count. This is the first thing examiners see — make it professional and accurate. 包含研究问题、学科和字数统计。 2. Contents Page 目录
All sections with page numbers. Helps examiners navigate your essay and shows organizational clarity. 所有章节及页码，便于考官快速定位。 3. Introduction 引言
Context, significance, and your research question stated clearly. Hook the reader and establish why this matters. 研究背景、意义和明确的研究问题。 4. Body 正文
Your argument developed across multiple sections with evidence, analysis, and evaluation. This is the heart of your EE — where you earn most of your marks. 用证据、分析和评估展开论证的核心部分。 5. Conclusion 结论
Summarize findings, answer the RQ, and acknowledge limitations. Do not introduce new information here. 总结发现、回答研究问题并承认局限性。 6. References 参考文献
Consistent citation style throughout (MLA, APA, Chicago, etc.). Every in-text citation must have a corresponding entry. 全文统一的引用格式，每条文内引用都必须对应一条参考文献。 The body section typically contains sub-sections that build your argument logically — from background and methodology through analysis and discussion to implications. A typical 4000-word EE might allocate: introduction (300 words), methodology (400 words), analysis and discussion (2800 words), conclusion (500 words). 正文通常包含若干子章节，从背景和方法论到分析和讨论。一篇典型的4000词EE可以这样分配：引言300词，方法论400词，分析与讨论2800词，结论500词。

三 如何选择研究话题 Choosing Your Topic

Topic selection is arguably the most important decision you will make for your EE. A bad topic cannot be rescued by good writing; a great topic almost writes itself. Choose something you are genuinely interested in — you will spend 40+ hours on this. 选题可能是你做EE最重要的决定。糟糕的选题无法靠好文笔挽救；出色的选题几乎可以自己写出来。选择一个你真正感兴趣的话题——你将花40多个小时在这上面。 Key principles for topic selection 选题关键原则: (1) It must fit within an IB subject — check the subject-specific guidelines for your chosen subject. (2) It must be narrow enough to cover in 4000 words — "The French Revolution" is too broad; "The role of women in the Parisian sans-culottes movement, 1792-1794" is focused. (3) There must be sufficient academic sources available — if you cannot find scholarly articles or books on your topic, you cannot write a research paper. (4) You need access to primary or secondary data where required — especially for science EEs that require experiments. Once you have a general topic area, you need to formulate your Research Question (RQ). This is the single most important sentence in your entire essay. Your RQ should be: specific, arguable, researchable, and clearly linked to your chosen IB subject. 一旦有了大致方向，你需要制定研究问题。这是整篇论文中最重要的一句话。RQ应该具体、可辩论、可研究、与所选IB学科明确相关。 Examples of strong RQs 优秀RQ示例: "How does the use of narrative perspective in Khaled Hosseini's The Kite Runner shape the reader's understanding of guilt and redemption?" (English A) "To what extent did the 2011 Fukushima nuclear disaster influence Germany's Energiewende policy between 2011 and 2022?" (History) "How does varying the concentration of sodium chloride (0%, 2%, 4%, 6%, 8%) affect the rate of osmosis in Solanum tuberosum (potato) tissue as measured by percentage mass change?" (Biology)

四 评分标准详解 Assessment Criteria Breakdown

The EE is assessed against five criteria (A through E), worth a total of 34 marks. Understanding what examiners are looking for under each criterion is essential for maximizing your score. EE根据A到E五个标准评估，共34分。理解考官在每个标准下寻找什么，对最大化分数至关重要。 Criterion A: Focus and Method (6 marks) 焦点与方法
This criterion assesses the clarity of your research question and the appropriateness of your methodology. Examiners check: Is the RQ clearly stated and appropriately focused? Is the methodology suitable for answering the RQ? Have you justified why you chose this approach? 评估研究问题的清晰度和方法的适当性。 Criterion B: Knowledge and Understanding (6 marks) 知识与理解
Demonstrates your grasp of the subject area. You need to use subject-specific terminology correctly, show understanding of key concepts, and place your research in its academic context. The sources you cite should reflect current scholarship in the field. 展示对学科领域的掌握，正确使用专业术语。 Criterion C: Critical Thinking (12 marks) 批判性思维
The largest criterion — worth more than a third of the total marks. Examiners look for: analysis rather than description, evaluation of sources, a well-reasoned argument, and critical engagement with your findings. This is where top students distinguish themselves. 最大的评分项，占总分三分之一以上。 Criterion D: Presentation (4 marks) 呈现
Covers formatting, structure, layout, and academic conventions. Your EE should look like a professional academic paper. Check: page numbers, consistent font, proper headings, correctly formatted citations, and appropriate use of charts and tables. 格式、结构和学术规范。 Criterion E: Engagement (6 marks) 投入度
Assessed through your Reflections on Planning and Progress Form (RPPF). Three mandatory reflection sessions: after choosing your topic (early reflection), midway through writing (interim reflection), and after completion (final viva voce). Show genuine intellectual growth, not just a log of what you did. 通过RPPF表格的三次反思评估。 Notice that Criterion C (Critical Thinking) carries 12 of the 34 total marks. This tells you where to invest your energy: do not just describe what sourc es say — analyze them, compare them, evaluate their reliability, and build your own argument from them. 注意C标准占12分，这告诉你应该把精力投入到哪里：不要只描述资料说了什么，要分析、比较、评估它们的可靠性，并从中构建自己的论证。

五 EE写作时间线与框架 Writing Timeline and Framework

A successful EE is not written in a weekend. The IB recommends approximately 40 hours of work, spread across several months. Here is a realistic timeline that aligns with most schools' internal deadlines. 一篇成功的EE不是周末赶出来的。IB建议大约40小时的工作量，跨越多个月份。 Month 1-2 第12月
Choose subject and topic. Read broadly. Draft a preliminary RQ. Meet with your supervisor. 选择学科和话题，广泛阅读，起草初步RQ，与导师见面。 Month 2-3 第23月
Conduct literature review. Refine RQ. Develop methodology. Build a source list with notes. First reflection session. 文献综述，完善RQ，制定方法论，建立带注释的文献清单。 Month 3-4 第34月
Gather data (experiments, surveys, textual analysis). Create a detailed outline with sub-arguments. Write first draft of body sections. Interim reflection. 收集数据，创建详细大纲，撰写正文初稿。 Month 4-5 第45月
Complete full draft. Write introduction and conclusion. Check all citations. Submit to supervisor for feedback. Revise based on comments. 完成全稿，撰写引言和结论，检查引用，提交导师反馈。 Month 5-6 第56月
Final revisions. Proofread carefully — read aloud to catch awkward phrasing. Format check. Submit RPPF with final reflection. Upload to IB. 最终修订，仔细校对，格式检查，提交RPPF，上传至IB。 Writing framework tip: structure each body paragraph around the PEEL method — Point (state your claim), Evidence (support with source), Explanation (analyze the evidence), Link (connect back to your RQ). This ensures every paragraph serves your argument. 写作框架技巧：每个正文段落使用PEEL方法——Point（提出观点），Evidence（证据支持），Explanation（分析解释），Link（回扣RQ），确保每个段落都为论证服务。

六 高分EE的秘诀 Tips for a High-Scoring EE

After analyzing hundreds of high-scoring EEs and examiner reports, certain patterns emerge. Here are the strategies that consistently produce A-grade essays. 在分析了数百篇高分EE和考官报告后，一些规律浮现出来。以下是持续产出A等论文的策略。 1. Start with a genuinely debatable RQ. If your RQ can be answered with a simple yes or no, or by summarizing what others have said, it is not a good RQ. A strong RQ forces you to weigh competing evidence and reach a nuanced conclusion. 如果你的RQ可以简单回答是或否，或通过总结他人观点回答，就不是好RQ。好的RQ迫使你权衡竞争性证据并得出细致结论。 2. Use a wide range of sources, not just textbooks. Academic journals, primary documents, interviews, datasets, and government reports all strengthen your authority. IB examiners reward students who go beyond the obvious. 使用广泛的来源，不仅仅是教科书。学术期刊、原始文献、访谈、数据集和政府报告都能增强你的权威性。 3. Critically evaluate your sources. For every source you cite, ask: Who wrote this? When? For what purpose? What biases might they have? Show the examiner that you do not take information at face value — this is what critical thinking looks like in practice. 对每个引用的来源问：谁写的？什么时候？出于什么目的？可能有什么偏见？向考官展示你不盲从信息。 4. Write the introduction last. You do not truly know what your essay argues until you have written the body. Write the body first, then craft an introduction that accurately previews your argument. Your supervisor will appreciate this too. 写完正文再写引言。在写完正文之前，你不会真正知道你的论文主张什么。 5. Take the RPPF reflection seriously. Many students treat the 500-word reflection form as an afterthought. It is worth 6 marks. Discuss setbacks honestly, explain how you overcame challenges, and demonstrate conceptual understanding. Many students write: "I learned to manage my time better." A better reflection: "Through analyzing conflicting interpretations of the Treaty of Versailles, I came to understand that historical narratives are shaped as much by the historian's context as by the evidence itself." 认真对待RPPF反思。许多学生把它当作事后工作，但它值6分。诚实地讨论挫折，解释如何克服挑战，展示概念性理解。 6. Proofread like an examiner. Read your essay out loud. Print it out and mark it with a pen. Check every in-text citation against your bibliography. Format headings consistently. These small things add up under Criterion D. 像考官一样校对：朗读、打印出来用笔标记、检查每条文内引用与参考文献的一致性。 7. Engage with counterarguments. The strongest EEs do not just present one side — they acknowledge opposing views and explain why their interpretation is more convincing. This demonstrates the highest level of critical thinking. 最强EE不只呈现一面之词，它们承认对立观点并解释为何自己的解释更有说服力。

七 常见错误与避坑指南 Common Mistakes to Avoid

❌ Too broad a topic 话题太宽
"The impact of social media" is a book-length topic. Narrow it to: "How Instagram's algorithm changes in 2022 affected political engagement among 16-18 year-olds in Singapore." 太宽泛的话题无法在4000词内充分讨论。 ❌ Descriptive, not analytical 描述性而非分析性
A summary of what happened is a C-grade essay. Analysis and evaluation earn A and B grades. Every paragraph should answer "so what?" 每个段落都应回答"那又怎样？" ❌ Ignoring subject-specific guidelines 忽视学科指南
Each subject has unique requirements. A History EE needs different treatment of sources than a Biology EE. Read the IB subject guide for your chosen subject carefully. 每门学科有独特要求，仔细阅读IB学科指南。 ❌ Poor time management 时间管理差
The most common reason for low EE scores is simply running out of time. The EE cannot be written well in the final week. Spread the work across months and set internal deadlines earlier than your school's. EE得分低的最常见原因就是时间不够用。 ❌ Weak or missing RQ 研究问题不清
If you cannot state your RQ in one clear sentence, you are not ready to write. Your supervisor should be able to read your RQ and immediately understand what your essay investigates. 如果你不能用一句话清晰陈述RQ，你还没准备好写作。 ❌ Plagiarism risks 抄袭风险
Even unintentional plagiarism results in serious consequences. Cite everything that is not your original thought. Use a plagiarism checker before submission. Paraphrase properly — changing a few words is still plagiarism. 即使是无意抄袭也会导致严重后果。

八 总结与最终建议 Final Thoughts and Summary

The Extended Essay is a marathon, not a sprint. It is designed to be difficult because the skills it teaches — independent research, critical analysis, academic writing, and intellectual honesty — are exactly what universities expect from first-year students. Students who take the EE seriously arrive at university better prepared than most of their peers. 拓展论文是一场马拉松而非短跑。它的设计本身就很难，因为它培养的技能——独立研究、批判性分析、学术写作、学术诚信——正是大学对大一新生的期望。 Your EE is also a unique asset for university applications. You can discuss it in your personal statement, bring it up in interviews, and even expand it into a research proposal. A strong EE on a topic related to your intended university major sends a powerful signal to admissions officers. EE也是大学申请的独特资产。你可以在个人陈述中讨论它，在面试中提及，甚至可以扩展成研究计划。 Remember the golden rules: narrow your topic until it hurts, let your RQ guide every paragraph, analyze rather than describe, and give yourself more time than you think you need. The difference between a C and an A is rarely intelligence — it is structure, analysis, and sustained effort over time. 记住黄金法则：把话题缩小到极致，让RQ指导每个段落，分析而不是描述，给自己比想象中更多的时间。 Good luck with your Extended Essay. The process will be challenging, but the skills you develop will serve you for life. 祝你的拓展论文顺利。过程充满挑战，但你所培养的技能将终身受用。
