IB EE结构完全指南 Extended Essay Structure Guide

什么是Extended Essay / What Is the Extended Essay

Extended Essay（简称EE）是IB文凭核心课程（IB Core）的三大组成部分之一，与TOK和CAS并列。它要求学生独立完成一篇4000字的学术研究论文，在IB导师的指导下，深入探究一个自己感兴趣的学科话题。EE不是简单的读书报告或文献综述：你需要提出一个清晰的研究问题（Research Question），通过分析、评估和论证来回答它，最终形成一篇结构严谨的学术论文。EE占IB总分3分（与TOK合并），虽然分值看似不大，但一篇出色的EE可以显著提升你的大学申请竞争力，让招生官看到你的独立研究能力和学术潜力。

The Extended Essay (EE) is one of the three core components of the IB Diploma Programme, alongside TOK and CAS. It requires students to independently complete a 4000-word academic research paper under the supervision of an IB teacher, exploring a topic of personal interest in depth within one of the approved IB subjects. The EE is not a book report or a literature review -- you must formulate a clear Research Question (RQ), answer it through analysis, evaluation, and argumentation, and produce a well-structured academic paper. The EE contributes up to 3 points toward your IB total (combined with TOK). While the point value may seem modest, an outstanding EE significantly strengthens your university application by demonstrating independent research capability and academic rigor to admissions officers.

EE学科选择 / Choosing Your EE Subject

选择EE科目是你写论文的第一步，也是最关键的决定之一。IB提供超过30个学科方向供选择，但你必须选择一个你正在学习（或至少熟悉）的IB学科。最受欢迎的EE学科包括：English A（文学分析）、History（历史探究）、Biology/Chemistry/Physics（实验科学）、Economics（经济分析）、Mathematics（数学建模）、Psychology（心理学实验或文献分析）以及Visual Arts（艺术评论）。选择科目时，问自己三个问题：我对这个学科真的有热情吗？我是否有足够的背景知识来提出有价值的研究问题？我的学校是否有合适的导师可以指导我？选择一个你真正感兴趣的科目，因为你将花40小时以上沉浸其中。

Choosing your EE subject is the first step and one of the most critical decisions you will make. The IB offers over 30 subject areas, but you must select one that you are currently studying (or at least familiar with). The most popular EE subjects include: English A (literary analysis), History (historical investigation), Biology/Chemistry/Physics (experimental sciences), Economics (economic analysis), Mathematics (mathematical modeling), Psychology (experimental or literature-based research), and Visual Arts (art criticism). When choosing a subject, ask yourself three questions: Am I genuinely passionate about this discipline? Do I have sufficient background knowledge to formulate a worthwhile research question? Does my school have a suitable supervisor to guide me? Pick a subject you truly care about -- you will spend 40+ hours immersed in it.

研究问题设计 / Crafting Your Research Question

研究问题（RQ）是EE的灵魂。一个好RQ必须满足三个标准：聚焦（focused）、可研究（researchable）、有争议空间（arguable）。避免过于宽泛的问题如"What caused World War II?"：这足够写十本书。改为聚焦版本如"To what extent did the Treaty of Versailles' economic reparations contribute to the rise of National Socialism in Germany between 1919 and 1933?"。RQ必须以问句形式呈现，通常使用"To what extent..."、"How..."、"In what ways..."等句式开头。一个好的RQ会让读者立刻明白你的研究方向和分析边界。在动笔前，用两个小时在Google Scholar或JSTOR上做初步文献检索，确保有足够的学术资源支撑你的研究。

The Research Question (RQ) is the soul of your EE. A good RQ must meet three criteria: focused, researchable, and arguable. Avoid overly broad questions like "What caused World War II?" -- that could fill ten books. Instead, craft a focused version such as "To what extent did the Treaty of Versailles' economic reparations contribute to the rise of National Socialism in Germany between 1919 and 1933?" Your RQ must be phrased as a question, typically starting with "To what extent...", "How...", or "In what ways...". A well-designed RQ immediately tells the reader your research direction and analytical boundaries. Before writing, spend two hours conducting preliminary literature searches on Google Scholar or JSTOR to confirm that sufficient academic sources exist to support your investigation.

EE整体结构框架 / Overall EE Structure Framework

IB对EE的结构有明确要求，所有EE必须包含以下部分（按顺序）：Title Page（封面）、Contents Page（目录）、Introduction（引言）、Body（正文，分为若干章节）、Conclusion（结论）、References/Bibliography（参考文献）。此外，Reflections on Planning and Progress Form（RPPF，规划与进展反思表）是强制提交的独立文件，不计入4000字限制。正文是EE的核心，通常占3000-3500字，分为3-5个分析章节，每个章节聚焦RQ的一个维度。4000字的限制是硬性的：超出部分考官不会阅读，超500字以上可能被扣分。请使用12号标准字体（如Times New Roman或Arial）、双倍行距、页码标注，给考官留下整洁专业的印象。

The IB has clear structural requirements for the EE. Every essay must include the following components in order: Title Page, Contents Page, Introduction, Body (divided into several chapters), Conclusion, and References/Bibliography. Additionally, the Reflections on Planning and Progress Form (RPPF) is a mandatory separate submission that does not count toward the 4000-word limit. The body is the core of the EE, typically occupying 3000-3500 words, divided into 3-5 analytical chapters, each focusing on one dimension of the RQ. The 4000-word limit is absolute -- examiners will not read beyond it, and exceeding by more than 500 words may result in a penalty. Use a standard 12-point font (such as Times New Roman or Arial), double spacing, and page numbers to present a clean, professional document to the examiner.

引言（Introduction）写法 / Writing the Introduction

引言通常占300-500字，作用是为读者提供进入论文的"地图"。一个优秀的引言应包含：研究背景：为什么这个话题值得研究，简要的学术背景铺垫；研究问题：清晰陈述你的RQ；研究方法：你打算如何回答RQ（文献分析？一手数据收集？实验？文本细读？）；论文结构预览：用一两句话概述正文各章将讨论什么。引言不需要过于冗长的文献综述：那是正文的事。引言的关键功能是让考官在读完引言后，完全理解你打算研究什么、为什么研究、以及怎么研究。许多高分EE的引言读起来像一篇微型研究提案。

The introduction typically occupies 300-500 words and serves as the "map" for readers entering your essay. A strong introduction should include: research context -- why this topic is worth investigating, with brief academic background; research question -- state your RQ clearly; methodology -- how you plan to answer the RQ (literature analysis? primary data collection? experiments? close reading?); and a structural preview -- one or two sentences outlining what each body chapter will discuss. The introduction does not need an extensive literature review -- that belongs in the body. The key function of the introduction is to ensure that the examiner, after reading it, fully understands what you intend to investigate, why, and how. Many high-scoring EE introductions read like miniature research proposals.

正文（Body）章节组织 / Organizing the Body Chapters

正文是EE的分析核心，你需要将论证拆分为逻辑连贯的章节。对于大多数EE，3-5个章节最合适。每个章节应该有一个明确的次问题（sub-question）或分析角度。以History EE为例：第一章可以建立历史背景和主要学术争论（historiography）；第二章分析一手资料证据；第三章讨论反面观点和局限性；最后综合各角度形成论证。对于科学EE：第一章介绍理论和已有研究；第二章描述实验方法和数据收集过程；第三章呈现和分析数据；第四章讨论误差来源和结果意义。每章结尾用一两句过渡句连接到下一章，确保读者跟随你的论证逻辑。记住：每段都应该服务于回答RQ：如果某段内容不能直接支持你的论证，删除它。

The body is the analytical core of your EE, and you need to break your argument into logically coherent chapters. For most EEs, 3-5 chapters is optimal. Each chapter should have a clear sub-question or analytical angle. For a History EE: Chapter 1 can establish historical context and the main historiographical debates; Chapter 2 analyzes primary source evidence; Chapter 3 discusses counter-arguments and limitations; the final synthesis ties all perspectives together. For a Science EE: Chapter 1 introduces theory and existing research; Chapter 2 describes methodology and data collection; Chapter 3 presents and analyzes data; Chapter 4 discusses sources of error and the significance of results. End each chapter with one or two transitional sentences linking to the next, ensuring your reader follows the logical flow of your argument. Remember: every paragraph should serve the purpose of answering your RQ -- if a section does not directly support your argument, cut it.

结论（Conclusion）写作 / Writing the Conclusion

结论通常占300-400字，不是对正文的简单重复。一个有力的结论应该：直接回答研究问题：基于你正文中的分析，给出明确的答案；总结关键发现：用3-5句话概括主要论证线索，而非逐章复述；讨论研究的局限性：坦诚承认你的方法或数据存在哪些不足；提出未来研究方向：这个问题还可以从哪些角度继续深入？最后，结论应该给读者留下一个持久的印象。如果可能，用一个有力的结束句将你的研究联系到更广阔的学术或现实意义中。避免在结论中引入全新的论点或证据：所有新材料都应该出现在正文中。

The conclusion typically occupies 300-400 words and is not a simple repetition of the body. A strong conclusion should: directly answer the RQ -- based on your analysis in the body, give a clear answer; summarize key findings -- in 3-5 sentences, encapsulate the main argumentative thread rather than reciting chapter-by-chapter; discuss limitations -- honestly acknowledge the shortcomings of your methodology or data; and suggest directions for future research -- what angles could further deepen this investigation? Finally, the conclusion should leave a lasting impression on the reader. If possible, end with a powerful closing sentence that connects your research to broader academic or real-world significance. Avoid introducing entirely new arguments or evidence in the conclusion -- all new material belongs in the body.

参考文献与引用格式 / References and Citation Format

EE要求严格的学术引用规范。IB接受多种引用格式，但你的学校通常会指定一种。常见格式包括：MLA（常用于语言文学）、APA（常用于社会科学和心理学）、Chicago（常用于历史）以及Harvard（常用于科学和经济）。无论选择哪种格式，必须在全文中保持一致。参考文献列表只包含你实际引用过的来源：不是你读过的所有材料。确保每一个在文中出现的引用都能在参考文献列表中找到对应条目，反之亦然。使用Zotero、Mendeley或EndNote等文献管理工具可以大幅降低格式错误的风险，并自动生成参考文献列表。IB考官非常重视学术诚信：任何引用缺失都可能构成抄袭，导致严重后果。

The EE demands rigorous academic citation standards. The IB accepts multiple citation formats, but your school will typically specify one. Common formats include: MLA (commonly used in language and literature), APA (commonly used in social sciences and psychology), Chicago (commonly used in history), and Harvard (commonly used in sciences and economics). Whichever format you choose, maintain absolute consistency throughout the essay. The reference list should only include sources you actually cited -- not everything you read. Ensure every in-text citation has a corresponding entry in the reference list, and vice versa. Using reference management tools like Zotero, Mendeley, or EndNote can dramatically reduce formatting errors and automatically generate your bibliography. IB examiners take academic integrity extremely seriously -- any missing citation can constitute plagiarism and lead to serious consequences.

RPPF反思表写作 / Writing the RPPF Reflections

RPPF（Reflections on Planning and Progress Form）是一份独立于EE正文的文件，记录你在研究过程中的三次正式反思。第一次反思（Initial Reflection）在确定RQ和初步研究计划后撰写：你选择该主题的动机是什么？你的初步研究思路是什么？你遇到了哪些挑战？第二次反思（Interim Reflection）在完成初稿后进行：你的研究问题是否调整了？你的论证方向是否发生了变化？你如何回应导师的反馈？第三次反思（Viva Voce Reflection）在最终提交前完成：回顾整个研究历程，你学到了什么？如果你重新开始，会做哪些不同的选择？三次反思总计不超过500字。RPPF虽然不直接计分，但考官会参考它来评估你的Engagement（Criterion E），所以请认真对待每一次反思，展现你在研究过程中的成长。

The RPPF (Reflections on Planning and Progress Form) is a document separate from the EE body that records your three formal reflection sessions during the research process. First Reflection (Initial): written after finalizing your RQ and initial research plan -- what motivated you to choose this topic? What is your preliminary research approach? What challenges do you anticipate? Second Reflection (Interim): written after completing your first draft -- did your RQ shift? Did your argument change direction? How did you respond to supervisor feedback? Third Reflection (Viva Voce): completed before final submission -- looking back at the entire research journey, what did you learn? If you started over, what would you do differently? The three reflections must total no more than 500 words. While the RPPF is not directly scored, examiners reference it to assess your Engagement (Criterion E), so take every reflection seriously and demonstrate your growth throughout the research process.

评估标准详解 / Assessment Criteria Breakdown

EE根据五个标准（Criterion A-E）评分，总分34分，对应A-E等级。Criterion A: Focus and Method（6分）：评估RQ的清晰度和研究方法的适当性。Criterion B: Knowledge and Understanding（6分）：评估你对所选学科的学术理论和概念的理解深度，以及术语使用的准确性。Criterion C: Critical Thinking（12分，分值最大）：评估你的分析、评估和论证能力，这是EE评分的最核心部分。Criterion D: Presentation（4分）：评估论文的格式、结构、引用和整体呈现质量。Criterion E: Engagement（6分）：基于你的RPPF反思，评估你在研究过程中的投入程度和思维发展。每个标准都有具体的评分描述词（descriptors），在开始写作前仔细阅读这些描述词，确保你的论文在每个维度上都能达到最高水平。

The EE is assessed on five criteria (Criterion A-E), with a total of 34 marks, mapped to A-E grades. Criterion A: Focus and Method (6 marks) -- evaluates the clarity of your RQ and the appropriateness of your methodology. Criterion B: Knowledge and Understanding (6 marks) -- evaluates the depth of your understanding of academic theories and concepts in your chosen subject, and the accuracy of your terminology use. Criterion C: Critical Thinking (12 marks, the largest weighting) -- evaluates your analytical, evaluative, and argumentative skills; this is the most critical part of EE assessment. Criterion D: Presentation (4 marks) -- evaluates the formatting, structure, citation, and overall presentation quality of your essay. Criterion E: Engagement (6 marks) -- based on your RPPF reflections, evaluates the depth of your engagement and intellectual development throughout the research process. Each criterion has specific level descriptors. Read these descriptors carefully before you start writing to ensure your essay can reach the highest level in every dimension.

常见结构错误 / Common Structural Mistakes

每年IB考官报告都反复提到相同的结构性问题，避免这些错误可以大幅提升你的得分。第一：RQ过于宽泛或模糊：如果你的RQ可以用"是/否"回答，说明它不够深入。第二：描述性过强而分析不足：不要把EE写成百科全书条目。每个事实陈述后，都应该跟上分析和评估。第三：结构失衡：某章2000字而另一章200字，说明论点组织有问题。第四：引言和结论过长：引言和结论加起来不应超过总字数的20%。第五：在结论中引入新论点：让考官困惑你的论证到底在哪里结束。第六：忽视反面观点：不讨论反面观点会削弱你的论证说服力，也表明Critical Thinking不足。第七：引用不足或引用格式混乱：这是最容易避免但最常见的扣分项。

Every year, IB examiner reports highlight the same structural issues. Avoiding these mistakes can significantly boost your score. First: an overly broad or vague RQ -- if your RQ can be answered with "yes/no", it is not deep enough. Second: excessive description with insufficient analysis -- do not turn your EE into an encyclopedia entry. Every factual statement should be followed by analysis and evaluation. Third: unbalanced structure -- if one chapter is 2000 words and another is 200, your argument organization is flawed. Fourth: overly long introduction and conclusion -- these combined should not exceed 20% of the total word count. Fifth: introducing new arguments in the conclusion -- this confuses the examiner about where your argument actually ends. Sixth: ignoring counter-arguments -- failing to discuss opposing views weakens the persuasiveness of your argument and signals insufficient Critical Thinking. Seventh: insufficient or inconsistent citations -- this is the easiest mistake to avoid yet the most common mark-losing issue.

时间规划与里程碑 / Timeline and Milestones

一篇成功的EE不是几周突击完成的：它需要一个跨越几个月的系统规划。建议的时间线：DP1第三学期（4-5月）：选择学科、确定导师、初步文献调研、形成RQ草案。DP1暑假（6-8月）：深入阅读、收集资料、完成注释书目、撰写详细大纲、开始初稿。DP2第一学期（9-10月）：完成初稿、提交给导师获取反馈、进行第一次和第二次RPPF反思。DP2第一学期（11-12月）：根据导师反馈修改、完善引用格式、完成第二次修改稿。DP2第二学期（1-2月）：最终定稿、格式检查、完成第三次RPPF反思（Viva Voce）、正式提交。关键原则：永远在截止日期前至少两周完成：给自己充足的缓冲时间应对意外情况。

A successful EE is not produced in a few weeks of cramming -- it requires systematic planning over several months. Recommended timeline: DP1 Term 3 (April-May): Select subject, confirm supervisor, conduct preliminary literature review, draft RQ. DP1 Summer Break (June-August): Deep reading, gather sources, complete annotated bibliography, write detailed outline, begin first draft. DP2 Term 1 (September-October): Complete first draft, submit to supervisor for feedback, complete first and second RPPF reflections. DP2 Term 1 (November-December): Revise based on supervisor feedback, polish citation format, complete second revised draft. DP2 Term 2 (January-February): Final editing, formatting check, complete third RPPF reflection (Viva Voce), formal submission. Key principle: always finish at least two weeks before the deadline -- give yourself ample buffer time for unexpected issues.
