IB TOK展评 35提示词 三件物品 950词

IB 的 Theory of Knowledge 里,展评(TOK exhibition)是唯一由本校老师打分的部分。它要求你用三件真实存在的物品,回答一条官方给定的知识问题,并在 950 词里说清每件物品和这条问题的关系。2022 年首次评估的这套安排一直沿用,2026 年的考生面对的还是同一份评估规则。很多学生以为展评是一场展览,功夫在布置和讲解上,其实被打分的只有那份文字文件。文件写成什么样,分数就是什么样,展台再漂亮也不进评分表。

The exhibition is the internally assessed half of Theory of Knowledge, and it is the part your own school controls from start to finish. Three real objects, one official prompt, a commentary capped at 950 words. What gets marked is the submitted file, never the display you build around it.

展评在 TOK 里的位置与分数权重

按 IBO 的《Theory of knowledge guide》,TOK 最低 100 小时,其中五个领域知识约 50 小时,核心主题与两个选修主题 32 小时,两项评估的准备 18 小时,展评占其中约 8 小时。展评满分 10 分,占 TOK 总成绩三分之一,论文占三分之二。它由本校 TOK 老师打分,样本送 IBO 做调节。学校判分过松或过严时,IBO 会把整所学校的分一起上调或下调,所以你手上那个分数未必是最终分。旧版课程的评估任务是口头陈述,2022 年首次评估起换成展评,重心从讲台表达挪到了书面论证。那 8 小时包括选题指导、找物品、写作与校内展示的安排,但真正进评分表的只有文件本身。

Under the IBO guide, TOK carries a minimum of 100 teaching hours. The exhibition takes about eight of them and one third of the final grade, with the essay taking the remaining two thirds. Your teacher marks it out of ten and a sample is sent to the IB for moderation. When a school is too generous or too harsh, every student's score shifts together, which is why the first number you see is provisional.

35 条提示词只能用原文

展评的题目不是自拟的。IBO 在指南里给了 35 条 IA prompts,你只能挑一条,而且一字不改。改写过但看得出是哪一条时,评分按原题处理,答偏的部分照扣。完全看不出用了哪一条,直接得零分。同一条提示词可以给全班共用,物品不能撞车,同班同学之间不允许共用任何一件物品。很多学生以为把题目改得顺口一点无所谓,这一步最容易丢分,因为阅卷时对照的就是指南原文。这 35 条在整份指南有效期内不变,不会每年换题,往届学生的选题经验可以直接借。抄进标题时连标点一起抄,一个词的差别也可能被判成改写。

The prompt is not yours to write. The IBO publishes 35 IA prompts and you pick one, word for word, without edits. Two students in the same class may share a prompt but never share an object, and a prompt nobody can identify scores zero. Those 35 questions stay fixed for the life of the guide, so last year's choices remain valid reference points.

核心主题与五个选修主题怎么定

指南建议把展评落在一个 TOK 主题上,要么是核心主题 Knowledge and the knower,要么是五个选修主题里的一个:知识与技术、知识与语言、知识与政治、知识与宗教、知识与原住民社会。主题本身不是评分项,但它决定你找物品的方向。选了知识与技术,物品自然会落到算法、设备、界面这类东西上;选了知识与语言,翻译、方言、术语表更顺手。很多学生以为主题必须和课上讲过的内容完全一致,其实它只是给你一个搜索范围,物品的取舍仍由提示词决定。同班同学选了同一主题也不算重复,物品各自独立即可。

The guide recommends anchoring the exhibition in a TOK theme, either the core theme or one of the five optional ones. The theme earns no marks by itself, it narrows where you hunt for objects. A technology theme pushes you toward devices and interfaces, while a language theme points at translation, dialect and glossaries.

三件物品要具体到能被别人找到

物品必须是具体、真实存在的东西,不是一类物品的统称。一张护照不算物品,你祖父 1971 年被边境盖上出境章的那本护照才算。指南允许用物品的照片,前提是照片拍的就是那件实物,不是图库里的同类示意图。三件物品还要各自承担不同的论证任务,不能三件都在说同一句话。常见的错误是三件物品同属一个领域,读起来像同一个例子换了三个外壳。物品不必昂贵或稀有,家里的旧物件、实验室里的器材、手机里的截图都能用,关键在你能否说清它的来历。挑物品时写一行字问自己:这件东西让提示词里的哪个词变得具体了。

An object has to be specific enough for a stranger to find it. A passport is a category; your grandfather's 1971 passport, stamped the week his family left, is an object. Photographs are allowed as long as they show the actual item rather than a stock image of its type. Three objects also need to do three different jobs, otherwise the exhibition reads as one example in three costumes.

交上去的是一个文件

指南要求每位学生交一个文件,里面含四项内容:清楚写明所选 IA 提示词的标题、三件物品的图片、逐件撰写的评论、以及相应的引用与出处。评论要识别每件物品并说明它具体的现实情境,说明为什么把它放进这次展评,并建立它与提示词的关联。字数上限 950 词,标题与参考文献不计入。展评是个人任务,不允许小组合作。文件之外那场校内公开展示要做,但它不进分数。图片要看得清物品本身,模糊的截图会拖累识别这一步。涉及原文引用或具体数字时,出处按学科惯例写清楚,不要留空。

What you submit is one file: a title naming the prompt, images of the three objects, a typed commentary on each object, and references. Each commentary has to identify the object and its real-world context, justify its inclusion, and link it to the prompt. The 950-word cap covers the commentary, while the title and reference list sit outside the count.

评论里的三个动作

IBO 的表述把评论拆成三个动作:识别与情境、说明入选理由、建立与提示词的关联。识别要给出时间、地点、归属,让人能定位这件东西;入选理由要回答它比同类物品多提供了什么;关联要解释这件物品如何让提示词里的某个词变得可讨论。三个动作缺一个,分数就停在中段。常见的错误是花大半篇幅描写物品长什么样,真正解释关联的句子只剩两三句。把描述压在全文三分之一以内,剩下的词留给推理。三个动作在文字上可以分开写,识别一段、理由一段、关联一段,读的人容易跟上。

The guide splits each commentary into three moves: identify the object and its context, justify why it belongs in this exhibition, and link it to the prompt. Identification needs a time, a place and an owner. Justification answers what this object shows that a similar one would not, and the link explains which word in the prompt it makes discussable.

950 词怎么分到三件物品上

三件物品平摊下来大约每件 300 词,其中识别约 50 词、关联约 100 词、入选理由约 100 词、收尾与出处约 50 词。这个分法不是 IBO 的规定,只是写作时的参考线。词数紧的时候先删泛论句,比如知识在当今社会很重要这一类句子,它们不带来任何分数。评分读到的是评论本身,超出 950 词的部分按说明不予考虑。标题、图片说明与参考文献可以写全,它们不占词数。某件物品的关联特别复杂时,可以把词数往它身上挪,另两件各减二十词也行。写完先数字数再动内容,顺序反了会反复超限。

Roughly 300 words per object is the working split: about 50 to identify, 100 to link, 100 to justify and 50 to close. None of that is an IB rule, it is a budget that keeps description from eating the reasoning. General lines about knowledge mattering in society buy nothing and should be the first thing you cut.

打分是整体印象而不是逐条勾选

展评用一条整体性标准打分,满分 10 分,分成 9 到 10、7 到 8、5 到 6、3 到 4、1 到 2 五档,另有 0 分。老师读完整份文件后选最贴近的一档,再在这一档里定高分或低分。它不像选择题那样逐条勾选,特征命中几条也不自动上档。处在 9 到 10 档的展评通常读起来像一个论证走了三步,每件物品把答案往前推一点。处在 5 到 6 档的展评三件物品都在,情境写得含糊,关联只有一半说得清。档与档之间没有硬边界,老师判断的是整体更像哪一档。

Marking is holistic. Your teacher reads the whole file, places it in one of five bands from 9 to 10 down to 1 to 2, then chooses the higher or lower mark inside that band. Nobody ticks four boxes and adds them up. A top-band exhibition reads like one argument in three steps, with each object pushing the answer further than the last.

先于文采起作用的几个上限

指南和评分说明里有几条上限,作用在文采之前。只交两件物品,最高 6 分;只交一件,最高 3 分;没有使用 35 条官方提示词中的任何一条,得 0 分。评论超过 950 词时,评分者按说明在词数上限处停止阅读,多写的部分不参与评分。这几条不涉及判断力,只涉及是否读完要求。很多学生以为多写一点总能多拿分,实际是先撞上限再谈质量。上限之外还有一条常被忽略的要求,展评必须个人完成,合作写出来的文件不能提交。

Several limits apply before style matters at all. Two objects cap the mark at 6, one object at 3, and a prompt that is not on the official list scores zero. Examiners stop reading at the 950-word mark, so anything past it is wasted rather than penalised. The task is also strictly individual, so a file written by two people cannot be submitted as it stands.

12 个 TOK 概念怎么用

指南列了 12 个 TOK 概念:evidence、certainty、truth、interpretation、power、justification、explanation、objectivity、perspective、culture、values、responsibility。展评不需要把它们全用上,每件物品挂一到两个就够,全篇要统一。写到证据时就用 evidence,不要中途换成 proof;写到解释时用 explanation,不要和 justification 混着用。常见的错误是概念只在开头出现一次,后面全是日常用语,读起来和 TOK 没什么关系。概念不必堆在句首,放在论证需要的地方更自然,读起来也不像贴标签。

The guide names twelve concepts, from evidence and certainty through to culture, values and responsibility. You do not need all of them. One or two per object, used consistently across the file, is enough. The usual slide is a concept appearing once in the opening line and never coming back, which makes a commentary read like a school report rather than a TOK task.

时间安排与初稿机会

指南把展评设计成 IB 第一年就能完成的任务,学校要设内部截止日,多数落在 DP1 的下半段。校内流程一般是选题、找物品、写初稿、老师反馈、定稿上传,其中初稿只有一次反馈机会。找物品最花时间,因为它要求你真能接触到那件实物,或者拿到它的照片与出处。这一步最容易拖到截止日前一周,然后被迫用随手可得的东西凑数,分数就停在中等。提前三四周开始找,通常能挑到更贴题的东西。学校一般会在 DP1 第二学期排统一进度,越早动手越有余地换物品。

The task is designed to be finished in the first year of the DP, with schools setting their own internal deadline. Most run the same sequence: choose a prompt, find objects, draft, get one round of teacher feedback, then submit. Finding objects is the slow part, because each one has to be something you can actually reach or document.

展评与论文的分工

TOK 的另一半是论文:从每年公布的 6 个题目里选 1 个,1600 词,外部评分,占三分之二。展评先做、论文后做,这个顺序有道理,因为两者考的是同一套动作,把抽象的知识问题落到具体材料上,再解释材料为什么支持这个判断。TOK 与拓展论文的等级合起来最多加 3 分,等级从 A 到 E。展评拿到 9 到 10 分对最终等级有帮助,但它不能替论文补分。把展评当成论文的练习,写法上会顺很多。论文的 6 个题目每年更换,展评的 35 条不变,先做展评也省去了等新题的时间。

The other half is the essay: one of six prescribed titles, 1,600 words, externally marked, worth two thirds of the grade. Doing the exhibition first makes sense because both tasks reward the same move, bringing an abstract question down onto specific material. TOK and the extended essay then combine for up to three bonus points, graded from A to E.
