What is the IB Extended Essay? 什么是IB拓展论文？

The IB Extended Essay (EE) is a mandatory 4,000-word independent research paper that forms part of the IB Diploma Programme core, alongside Theory of Knowledge (TOK) and Creativity, Activity, Service (CAS). It offers students the opportunity to investigate a topic of personal interest within one of the six IB subject groups. EE is assessed on a scale from A (highest) to E (lowest). Combined with your TOK grade, it can contribute up to 3 bonus points toward your diploma total. An E in either EE or TOK means you cannot receive the diploma — so this paper matters enormously. IB拓展论文是IB文凭课程的核心组成部分之一，要求学生独立完成一篇4000字的研究论文。与知识理论（TOK）和创造性活动服务（CAS）并列，EE是获取IB文凭的必修项。评分从A到E，与TOK成绩结合后最多可获得3个额外加分。如果EE或TOK任一获E，则无法获得文凭——所以这篇论文至关重要。

Choosing Your EE Subject and Topic 如何选择EE学科与题目

Subject selection is your first and most consequential decision. You must pick a subject you're currently studying at IB — typically at Higher Level (HL), though Standard Level (SL) is permitted — and write a paper within that discipline's methodology. Most students choose: English A Literature, History, Biology, Economics, or Psychology. The topic must be narrow enough to investigate deeply within 4,000 words, yet broad enough to sustain meaningful analysis. A common mistake is choosing something too broad ("The French Revolution") or too narrow ("The use of metaphor in one sonnet"). Aim for something like: "To what extent did the Treaty of Versailles's economic clauses contribute to hyperinflation in Weimar Germany, 1919–1923?" EE的学科选择是最关键的第一步。你必须选择一门正在学习的IB学科（通常建议选择高级课程HL，标准课程SL也可），并在该学科方法论框架内撰写论文。最常见的EE学科包括：英语文学、历史、生物、经济学和心理学。 题目必须足够聚焦，能在4000字内深入探讨，同时又要足够宽广以支撑有意义的分析。常见的错误是选题过于宽泛（如"法国大革命"）或过于狭隘（如"某首十四行诗中的比喻"）。理想的题目如："凡尔赛条约的经济条款在多大程度上导致了魏玛德国1919-1923年的恶性通货膨胀？"

The Research Process: From Question to Draft 研究流程：从问题到初稿

Effective EE research follows a structured path. Begin with secondary source reading to build foundational knowledge. Then formulate a specific research question. Follow with targeted primary and secondary research, maintaining careful bibliographic records from day one. Your supervisor is your most valuable resource. IB requires three mandatory reflection sessions, but the best students meet more frequently. Come to each meeting with specific questions, not vague progress reports. Your Reflections on Planning and Progress Form (RPPF) is assessed — make each reflection substantive, showing genuine intellectual growth. 高效的EE研究遵循结构化路径。先通过二手资料阅读建立基础知识储备，然后形成具体的研究问题，接着进行有针对性的原始研究和文献调研。从第一天起就要仔细记录参考文献。 导师是你最宝贵的资源。IB要求三次强制性反思会议，但最优秀的学生会更多次与导师交流。每次会议应带着具体问题去，而不是给出模糊的进度报告。你的计划与进展反思表（RPPF）会被评分——每次反思都要有实质内容，展现真正的学术成长。

Structuring Your Essay 论文结构搭建

A strong EE follows a clear academic structure: Title Page — research question, subject, word count. Abstract (300 words) — research question, methodology, main findings, conclusion. This is often written last. Table of Contents — with page numbers. Introduction (300–400 words) — hook, context, your research question, and a roadmap of your argument. Body (3,000–3,500 words) — organized into clearly headed sections, each advancing one aspect of your argument. Conclusion (300–400 words) — synthesize findings, answer the research question, acknowledge limitations, and suggest future research. References / Bibliography — consistent citation style throughout (MLA, APA, Chicago — check your subject requirements). Appendices (optional) — raw data, interview transcripts, etc. 一篇优秀的EE遵循清晰的学术结构：标题页、摘要（300字，通常在最后写）、目录、引言（300-400字）、正文（3000-3500字，分章节推进论证）、结论（300-400字，综合发现、回答研究问题、说明局限性）、参考文献，以及可选附录。

Assessment Criteria Explained 评分标准详解

The EE is graded against five criteria, totaling 34 marks: Criterion A: Focus and Method (6 marks) — Is your research question sharp? Is your methodology appropriate? Criterion B: Knowledge and Understanding (6 marks) — Do you show disciplinary expertise and use subject-specific terminology correctly? Criterion C: Critical Thinking (12 marks) — This is the big one. Are you analyzing, not just describing? Do you evaluate sources, consider counterarguments, and draw reasoned conclusions? Criterion D: Presentation (4 marks) — Formatting, structure, citations. Criterion E: Engagement (6 marks) — Assessed via your RPPF reflections. Shows your intellectual journey. Notice that Criterion C (Critical Thinking) is worth 12 marks — more than a third of the total. Your essay must argue, not summarize. Every paragraph should advance your thesis, not just report what sources say. EE按五项标准评分，总分34分：A-重点与方法(6分)，B-知识与理解(6分)，C-批判性思维(12分，占比最大)，D-呈现(4分)，E-投入度(6分，通过RPPF评估)。注意C项占12分，超过总分的三分之一——你的论文必须论证，而非总结。

Common Pitfalls and How to Avoid Them 常见误区与避坑指南

Pitfall 1: A descriptive rather than analytical essay. Fix: After every paragraph, ask yourself "So what?" If the paragraph only reports facts, revise it to argue a point. Pitfall 2: Over-reliance on a single source or textbook. Fix: Use diverse sources — academic journals, primary documents, contrasting scholarly viewpoints. Pitfall 3: Ignoring the word count. The 4,000-word limit is absolute. Examiners stop reading at 4,000. Overwriting is as bad as underwriting (which rarely scores above C). Pitfall 4: Procrastinating the RPPF. The three reflections cannot be written the night before submission. They must show authentic engagement over time. Pitfall 5: Poor citation management. Use Zotero, Mendeley, or even a simple spreadsheet from day one. Reconstructing a bibliography at the end is painful and error-prone. 常见误区：写成描述性而非分析性文章、过度依赖单一来源、忽视字数限制（超4000字考官直接停止阅读）、拖延RPPF反思写作、参考文献管理混乱。从第一天起使用Zotero或Mendeley管理引用。

Timeline and Planning 时间规划建议

Most IB schools assign the EE across Year 1 and early Year 2. A realistic timeline: Months 1–2: Choose subject and supervisor. Brainstorm topics. Months 3–4: Narrow to a specific research question. Begin reading. Submit Reflection 1. Months 5–7: Complete research. Outline the essay. Write a first draft. Submit Reflection 2. Months 8–9: Revise based on supervisor feedback. Polish writing. Submit Reflection 3. Final month: Proofread meticulously. Format citations. Submit. Build buffer time into every stage. The students who score A and B are rarely the most brilliant — they are the most consistent and well-planned. 大多数IB学校将EE安排在Year 1和Year 2初期。合理的时间线：第1-2月选定学科和导师、头脑风暴；第3-4月确定研究问题、开始阅读、提交反思1；第5-7月完成研究、拟定大纲、写初稿、提交反思2；第8-9月根据反馈修改、打磨文字、提交反思3；最后一个月精校、排版引用、提交。每个阶段都要留缓冲时间。得A和B的学生往往不是最聪明的，而是最有规划、最持之以恒的。

Final Tips for Success 成功秘诀

1. Read past high-scoring EEs in your subject. The IB publishes exemplars — study them. Notice how A-grade essays frame arguments, use evidence, and engage with counterarguments. 2. Your research question is a compass. Tape it above your desk. Every paragraph should point toward answering it. If a paragraph doesn't, cut it or reframe it. 3. Write the introduction last. You don't know what you're introducing until you've written it. The abstract is a summary of the finished product, not a plan. 4. Use your supervisor strategically. They cannot edit your work, but they can tell you when an argument is weak, a source is questionable, or a section is confusing. 5. Proofread on paper. Print your essay. Errors you miss on screen will leap off the printed page. 阅读往届高分EE范文——IB发布了优秀范例，认真学习。研究问题是你的指南针，每段都应指向回答它。引言和摘要在最后写。善用导师，他们不能替你修改，但能指出论证薄弱之处。打印出来校对——纸上看到的错误比屏幕上多得多。 📞 需要 IB 课程辅导？ 资深IB导师一对一指导 · EE选题与论文批改 · 学科辅导全覆盖 📱 16621398022 同微信 或访问 aleveler.com 了解更多课程详情
