IB TOK展览全攻略：三件物品与950字评论 | IB TOK Exhibition Guide: Three Objects and the 950-Word Commentary

IB TOK展览全攻略：三件物品与950字评论

一、TOK展览是什么？它与TOK论文的分工 / What Is the TOK Exhibition and How Does It Differ from the Essay?

TOK（Theory of Knowledge，认识论）是IBDP三大核心课程之一。从2022年首次评估起，TOK的内部评估从口头展示改为展览：学生围绕官方提供的一个提示题，挑选三件来自真实世界的物品，写出最多950字的评论，逐件说明物品与提示题的联系。展览由校内教师评分，再由IB官方抽样复核，占总评的33%；另一项评估是外部考官评分的TOK论文，占67%。两者成绩与EE（拓展论文）一起按矩阵换算为A到E等级，最高可为IB文凭贡献3个加分点，拿到E则无法获得文凭。

Theory of Knowledge is one of the three core components of the IB Diploma. Since first assessment in 2022, the TOK internal assessment has been the exhibition, which replaced the old oral presentation. Each student chooses one prescribed prompt, selects three objects from the real world, and writes a commentary of no more than 950 words explaining how each object links to that prompt. The exhibition is marked by the classroom teacher and a sample is externally moderated by the IB; it carries 33 percent of the TOK grade, while the externally assessed essay carries 67 percent. The two results enter the TOK and EE matrix that awards 0 to 3 bonus points toward the diploma, and a grade E in either component means the diploma is not awarded at all.

二、35个规定提示题：原样选择其一 / The 35 Prescribed Prompts: Choose Exactly One, Word for Word

提示题是官方指南中列出的35个知识问题，学生必须从中原样选择一个，不能改动措辞，也不能自创题目。例如What counts as knowledge?（什么才算知识？）、Are some types of knowledge more useful than others?（某些类型的知识是否更有用？）、Who owns knowledge?（知识归谁所有？）都是典型题目。选好之后，三件物品必须全部服务于这同一个提示题。同一班级允许有多位学生选择同一个提示题，但展览必须独立完成，不允许小组合作。如果展览没有基于规定提示题，作品直接得0分，这是最常见的致命失误。

The prompts are 35 knowledge questions published in the official TOK guide. You must choose exactly one, keep its wording unchanged, and never invent a question of your own. Typical examples include What counts as knowledge?, Are some types of knowledge more useful than others? and Who owns knowledge?. Once chosen, all three objects must connect to that single prompt. Several students in the same class may use the same prompt, but every exhibition is individual work and group work is not permitted. An exhibition that is not based on a prescribed prompt receives zero, which is the most common fatal mistake of all.

三、三件物品的选择标准：具体、真实、可论证 / Choosing Three Objects: Specific, Real-World and Defensible

物品必须具体、真实、可论证。IB官方明确反对泛化的类别：一本教科书太笼统，而我高二用的那本IB生物课本才是合格的具体物品。物品可以来自校园、家庭、网络生活或课外活动，官方示例包括政治领袖的一条推文、毕加索名画《格尔尼卡》的图片、学生自己的EE论文、体育课上用过的篮球等。正确的选物顺序是：先吃透提示题里的知识问题，再寻找能照亮这个问题的物品；反过来先选物品再硬凑题目，评论往往牵强。每件物品都应当有具体背景可以交代，背景越清晰，评论越好写。

Objects must be specific, real and defensible. The IB explicitly rejects generic categories: a textbook is too vague, whereas the IB Biology textbook I used in Grade 11 is a legitimate specific object. Objects may come from school, home, online life or extracurricular activities. Official examples include a political leader's tweet, an image of Picasso's Guernica, the student's own extended essay, and a basketball used in PE lessons. The correct order of work is to understand the knowledge question inside the prompt first, then hunt for objects that illuminate it; picking objects first and forcing a connection afterwards usually produces a weak commentary. Every object should have a concrete context you can describe, and the clearer the context, the easier the writing becomes.

四、数字物品与实物：图片、推文与引用规范 / Digital and Physical Objects: Images, Tweets and Referencing Rules

物品既可以是实物，也可以是数字物品。如果实物不便展出，例如一幅收藏在博物馆里的名画，可以用它的照片代替；数字物品的典型例子是政治人物的推文、新闻文章或网络表情包。规则要求每件物品的图片必须标注来源并正确引用，数字物品同样要给出出处。提交时只需一个文件，包含：写明提示题的标题、三件物品的图片、每件物品的评论，以及参考文献。注意布展展示环节本身不计入正式评分，但学校通常会组织展览活动，让学生的作品面向同学、家长和社区展示。

Objects may be physical or digital. When a physical object is impractical to display, such as a famous painting kept in a museum, a photograph of it is acceptable. Typical digital objects include a politician's tweet, a news article or an internet meme. Every image must be referenced correctly, and digital objects must include their source as well. The submission is a single file containing a title that states the prompt, images of the three objects, a commentary on each object, and citations. The showcase stage, where the exhibition is displayed to classmates, parents and the school community, is not part of the formal assessment, but schools usually organise it so students can share their work.

五、950字评论的构成与字数分配 / The 950-Word Commentary: Structure and Word Allocation

评论全文上限950字，不含参考文献。官方对每件物品的评论有明确要求：识别物品及其具体现实背景、论证它为什么被选入展览、解释它与提示题的联系。950字通常按三件物品均分，每件约300字，另外留出少量字给一个极简的引入。字数上限很紧，所以不要写冗长的开头和结尾，把篇幅全部留给物品与提示题的分析。没有最低字数要求，但评论过短通常意味着分析不足，教师很难给出高分。写完后务必逐字统计，超字数会被直接扣分。

The commentary has a hard ceiling of 950 words, excluding references. For each object the official requirements are identical: identify the object and its specific real-world context, justify why it was chosen, and explain its link to the prompt. A typical allocation splits the 950 words roughly equally, around 300 per object, with a few words left for a minimal introduction. Because the limit is tight, avoid long openings and conclusions, and spend the space on analysing the object-prompt link. There is no minimum length, but very short commentaries usually signal underdeveloped analysis that teachers find hard to reward. Count the words carefully before submission, since going over the limit is penalised directly.

六、每个物品评论的四步写作模板 / A Four-Step Template for Each Object Commentary

每个物品的评论都可以用四步模板推进：第一步，用一两句话介绍物品是什么、来自哪里；第二步，交代物品的具体背景，说明它为什么有代表性；第三步，正面论证物品如何回应提示题，自然地使用TOK概念，例如共有知识与个人知识、证词、语言、情感、理性等；第四步，换一个视角审视，承认这个物品解释的局限或反例。优秀评论的关键不是堆砌术语，而是让物品的具体细节与知识问题产生真实的对话。三件物品各自独立成段，段与段之间不必强行串联。

A reliable four-step template works for every object. First, introduce the object in one or two sentences: what it is and where it comes from. Second, establish its specific real-world context and explain why that context is representative. Third, argue directly how the object responds to the prompt, using TOK concepts naturally, such as shared and personal knowledge, testimony, language, emotion or reason. Fourth, step back and acknowledge a limitation or counter-perspective. Strong commentaries do not pile up jargon; they let the concrete details of the object enter a genuine conversation with the knowledge question. The three commentaries stand independently, and there is no need to force links between the objects themselves.

七、主题如何帮你缩小选物范围 / Using a Theme to Narrow Down Your Object Choices

TOK课程包含一个核心主题知识者与知识，以及五个可选主题：科技与知识、语言与知识、本土社会与知识、宗教与知识、政治与知识。官方强烈建议把展览扎根在某个主题里，因为主题能帮学生快速缩小选物范围，让三件物品共享一个知识视角。例如选择语言与知识主题的学生，可以围绕翻译错误、官方文件措辞、母语与二语差异来组织物品，评论会显得更连贯、更有深度。即使提示题本身没有主题标签，用主题思路筛选物品也是最高效的起步方式。

The TOK course has one core theme, knowledge and the knower, plus five optional themes: knowledge and technology, knowledge and language, knowledge and indigenous societies, knowledge and religion, and knowledge and politics. The IB strongly recommends rooting the exhibition in a theme, because a theme helps you narrow down object choices quickly and gives the three objects a shared knowledge perspective. A student working with knowledge and language, for example, might organise objects around translation errors, the wording of official documents, or differences between first and second language, producing a more coherent and deeper commentary. Even though the prompt itself carries no theme label, using theme thinking to filter objects is the most efficient way to start.

八、评分标准解读：链接的说服力决定分数 / The Assessment Instrument: Convincing Links Decide Your Mark

展览没有标准答案，教师依据官方评估量表做整体判断，核心看三件事：物品与提示题的联系是否明确、论证是否令人信服、解释是否展现了对TOK概念的理解。评量表从优秀到基础分若干档，三项要求同时满足才可能拿到最高档。教师完成评分后，IB会抽取样本送外部复核，教师给出的分数可能被上调或下调，所以写作目标应当是让校外的审核者也信服，而不只是让本校老师满意。与其追求术语数量，不如把每个联系论证到位。

There is no model answer; marking follows the official assessment instrument, applied holistically by the teacher. The instrument focuses on three things: whether each object-prompt link is explicit, whether the justification is convincing, and whether the explanation shows genuine understanding of TOK concepts. It runs in bands from excellent down to elementary, and the top band requires all three requirements at once. After teacher marking, the IB moderates a sample of exhibitions externally and scores can be adjusted up or down, so the real goal is to write work that convinces an outside moderator, not merely the classroom teacher. Chasing vocabulary quantity is pointless; arguing each link properly is what earns the marks.

九、教师反馈规则：只有一次改稿机会 / Teacher Feedback Rules: You Get One Draft, Then It Is Final

教师只能对一版草稿给出反馈，之后提交的必须是终稿。反馈可以是口头或书面建议，但教师不能替学生修改内容。这意味着改稿机会非常宝贵：建议动笔前先和老师确认提示题与三件物品的选择，把第一版草稿认真打磨后再交给老师，收到意见后集中修改一次，然后定稿。学校通常为展览任务预留约8小时教学时间，包含讲解要求、答疑和真实性核查。学术诚信要求所有工作必须完全独立完成，教师会核查引用与内容真实性。

Teachers may give feedback on only one draft, and the next version handed in must be the final submission. Feedback can be oral or written advice, but the teacher may not edit the work. This makes the single draft extremely valuable: confirm your prompt and object choices with the teacher before writing, polish the first draft seriously, then use the feedback for one focused revision before submitting the final version. Schools typically allocate about eight teaching hours to the exhibition task, covering the requirements, questions and authenticity checks. Academic honesty demands that the work is entirely your own, and teachers will verify citations and the authenticity of the content.

十、常见错误与避坑清单 / Common Mistakes and a Checklist of Pitfalls to Avoid

最常见的失分原因有五个：一是物品过于泛化，例如写手机而不是某台具体的手机及其某个功能；二是评论变成物品介绍，通篇描述物品却忘了回答提示题；三是超过950字上限被硬性扣分；四是物品与提示题的联系牵强，需要读者自己脑补；五是堆砌TOK术语却不解释其含义。交稿前请逐项自检：提示题是否原样使用？每件物品是否具体且来自现实世界？评论是否写全了背景、论证与联系三步？参考文献是否完整？总字数是否在950以内？

The five most common mark-losers are: objects that are too generic, such as a phone rather than one specific phone and a feature of it; commentaries that describe the object instead of answering the prompt; exceeding the 950-word limit and being penalised; forced connections between objects and the prompt that make the reader do the work; and TOK jargon that is never explained. Before submission, run a final checklist: is the prompt used word for word? Is every object specific and drawn from the real world? Does each commentary cover context, argument and link? Are all references complete? Is the total under 950 words?

十一、四周时间线与布展展示环节 / A Four-Week Timeline and the Exhibition Showcase

建议用四周推进：第一周通读35个提示题，选出一个自己真正有想法的，结合某个主题初步列出6到8个候选物品；第二周确定三件物品，与老师确认可行性，开始逐件写评论初稿；第三周完成第一版全文交给老师，按反馈修改并定稿；第四周核查引用与字数后提交文件，同时准备布展：打印图片、写展签、设计摆放顺序，让参观者一眼看懂三件物品与提示题的关系。布展虽然不计入正式评分，但它是向同学和家长展示TOK思考的好机会，值得认真对待。

A four-week plan works well. Week one: read all 35 prompts, choose one you genuinely care about, and shortlist six to eight candidate objects linked to a theme. Week two: settle on the three objects, confirm feasibility with your teacher, and draft the commentary for each one. Week three: complete the first full version, hand it in for feedback, and revise to the final version. Week four: check citations and the word count, submit the file, and prepare the display by printing images, writing captions and arranging the objects so visitors can instantly see how all three connect to the prompt. The showcase is not marked, but it is a great chance to share your TOK thinking with classmates and parents, so it deserves real effort.
