IB核心课程EE与TOK高分技巧全攻略

IB Core 是什么？| What is IB Core?

IB文凭课程的核心（Core）由三部分组成：知识论（TOK）、拓展论文（EE）和创造·行动·服务（CAS）。三者共同构成IB教育理念的核心——考察你的批判性思维、独立研究和反思能力。满分3分的核心分数，直接影响最终总成绩，从"差点拿不到文凭"到"稳稳拿下45分"。很多同学只盯六门学科成绩，忽视了核心部分——这恰恰是拉开差距的关键。The IB Core — TOK, EE, and CAS — tests your critical thinking, independent research, and reflection. Worth 3 bonus points, it can make the difference between barely scraping a diploma and hitting 45.

拓展论文EE：选题决定一切 | EE: Topic Is Everything

EE是你IB生涯中最长的独立研究项目——4000字，自选题目，自选学科。选对题目，成功一半。选题三原则：①必须在IB学科范围内；②必须有学术争议或可讨论空间（纯描述性题目 = 低分）；③必须有足够学术资源支撑。最好在一个熟悉的学科里，找到足够窄、足够深、有足够文献的切入点。The EE is your longest IB project — 4,000 words. Pick the right topic and you're halfway there. Three rules: ① within an IB subject; ② genuine academic debate (purely descriptive = low marks); ③ sufficient scholarly sources. Find a narrow, deep angle in a subject you know well.

TOK论文与展览：批判思维的真战场 | TOK Essay & Exhibition

TOK论文：IB每年发布六个命题，选一个写1600字论文。不要写成"我同意/不同意"——要写"这个命题提出了什么知识问题，不同知识领域如何看待它"。TOK展览：选三个物件，连接IA提示，950字内解释。关键在选物件——选有故事、有争议、有意外知识维度的东西。旧地图、删除的代码、被禁的书——这些比教科书更能展示你的TOK理解。Each year IB releases six Prescribed Titles — pick one for a 1,600-word essay. Don't write "I agree/disagree" — analyze what knowledge question the title raises across Areas of Knowledge. The TOK Exhibition: three objects linked to an IA Prompt, 950 words. Choose objects with a story — an old map, deleted code, a banned book — these reveal TOK thinking far better than textbooks.

CAS：不只是凑时间 | CAS: More Than Counting Hours

CAS没有分数，但没有CAS拿不到文凭。最常见错误：把CAS当"凑满150小时的待办清单"。IB考官看重反思，不是活动数量。每完成一个活动立刻写反思，用IB反思模型（描述→感受→评估→分析→结论→行动计划）。好的反思不是"今天做了什么"，而是"如何改变了我，收获了什么能力"。CAS carries no grade but is mandatory for the diploma. Examiners value reflection, not volume. Write reflections immediately after each activity using the IB model (Describe → Feelings → Evaluate → Analyze → Conclude → Action). Strong reflections show how you changed, not what you did.

时间线规划：别等到最后三个月 | Timeline Planning

IB核心部分最大敌人是拖延。EE需要3-4个月：第1月选题+文献调研，第2月大纲+引言，第3月正文，第4月修改+引用校对。DP1暑假是最重要的时间窗口——完成EE初稿和TOK展览，DP2压力减半。CAS保持每两周一篇反思的节奏，比期末狂补有效得多。The biggest enemy is procrastination. EE needs 3-4 months: topic+lit review, outline, writing, revision. DP1 summer is your critical window — finish the EE draft and TOK exhibition then, and DP2 stress halves. CAS: one reflection every two weeks beats last-minute cramming.

常见扣分陷阱 | Common Pitfalls That Cost You Marks

EE丢分重灾区：①引用格式不一致——MLA、APA或Chicago选一用到底；②超4000字——超字部分不被阅读；③研究方法不明确——在引言中说清楚你的研究身份。TOK常见问题：①把TOK论文写成学科论文——分析"知识如何产生"，不是总结学科知识；②展览物件过于平庸——三物件间需要对比和张力。CAS致命伤：反思只描述不分析——"今天去了养老院，感觉不错"不是反思，"意识到代际沟通中非语言交流的重要性"才是。EE marks lost: ① inconsistent citations — pick MLA, APA, or Chicago; ② exceeding 4,000 words; ③ unclear methodology. TOK pitfalls: writing a subject essay instead of analyzing knowledge; bland exhibition objects. CAS: descriptive "I did X" is not reflection — show what you learned.

总结：核心3分是你最该拿的分数 | Conclusion
