IB心理学 ERQ 论文结构 概念驱动 评分思路
IB 心理学的新版指南在 2025 年 8 月开始首教，2027 年 5 月首次考试，ERQ 这道长论述题也跟着换了位置和分值。旧版里 22 分的论文题，现在落在 Paper 1 的 Section C，只值 15 分，而且题目由一个概念、一个内容单元、一个语境拼出来。分值变小不等于更轻松，因为评分口径从记得多少研究转向能不能用一个概念把材料组织成论证。这篇文字把 ERQ 的骨架拆开：题目怎么读，段落怎么排，评价写在哪里，时间怎么分，还有哪些写法在新版里拿不到分。
The new DP psychology guide has been taught since August 2025 and is first examined in May 2027, and the extended response question moved with it; what used to be a 22-mark essay now sits in Paper 1 Section C at 15 marks, assembled from one concept, one content unit and one context. Fewer marks do not make the task easier, because the marks now sit with conceptual argument rather than recall of study details. This piece works through the shape of the answer, from reading the question to ordering the paragraphs, placing evaluation and managing the clock.
Paper 1 的三节结构与 35 分的分法
先说位置。Paper 1 时长 1 小时 30 分钟，SL 与 HL 用同一份卷子，总分 35 分。Section A 是两道必答短答题，每题 4 分，考三个内容取向里被抽中的两个，题干只要求解释一个心理学术语并配一个例子。Section B 也是两道必答短答题，每题 6 分，题目给一段不熟悉的情境，学生要把内容知识搬进情境里用。Section C 才是 ERQ，两道概念题里选一道，答完得 15 分。三节加起来是 8 加 12 加 15。IBO 官网的评估表把 Paper 1 记在 SL 的 35%、HL 的 25%，内部评估的研究提案 24 分，在 SL 占 30%、HL 占 20%。
Paper 1 lasts 1 hour 30 minutes and is shared by SL and HL, worth 35 marks in total; Section A carries two compulsory short-answer questions at 4 marks each, and Section B carries two more at 6 marks each, both of which apply content to an unseen situation. The extended response sits in Section C, where you choose one of two concept-based titles and write for 15 marks. In the assessment outline published by the IBO, Paper 1 is weighted at 35% for SL and 25% for HL, while the internal assessment research proposal counts for 30% and 20% respectively.
一道 ERQ 由概念、内容、语境拼成
题目不会直接问请介绍某个理论，而是把三样东西扣在一起。第一样是六个概念之一，也就是 bias、causality、change、measurement、perspective、responsibility。第二样是一个内容单元，例如某个取向里的某个术语或理论。第三样是一个语境，从四个语境里取一个。IB 的教师支持材料把这道题的构造写得很清楚：每道题都是一个概念、一个内容单元、一个语境的组合。所以读题的第一步是圈出概念词和语境词，而不是先想自己记得哪些研究。概念是论证的镜头，语境是范围，内容只是素材。
A Section C title is assembled from three parts: one of the six concepts, one content unit, and one context. Because the concept acts as the lens and the context fixes the boundary, the first move in the exam is to mark those two words rather than to recall studies. A question set in human development about measuring theory of mind is really testing the concept of measurement.
命令词决定论证的形态
Section C 的题目里，命令词是第一个要圈出来的词。命令词 discuss 要求把不同解释摆在一起权衡，最后给出一个站得住的结论。命令词 evaluate 要求先判断强弱点，再作出评价。有些题写 to what extent，这类要给出程度上的区分，而不是简单的对或错。新版 Section C 最常见的是 discuss 与 evaluate 两个。圈出命令词之后，用一句话写下你的判断，这句话就是全文的主线。写完回读一遍，确认每一段都在为这句判断服务。如果命令词是 evaluate 而正文只有描述，读卷的人只会看到没有答题的段落。
Command terms decide the shape of the argument; discuss asks for competing explanations to be weighed, evaluate asks for a judgement on strengths and limitations, and to what extent asks for a graded position. Most Section C titles use discuss or evaluate. A response that describes content without reaching a position has not answered the question, however accurate the content may be.
引言要做的三件事
引言要做三件事：拆题，给概念下定义，交代全文的论证路线。拆题是把题目里的概念词与语境词点出来，让读者看到你打算怎么理解这道题。给概念下定义要用心理学口径，而不是词典口径，例如因果指的是哪一类因果。交代路线是说明先谈什么、后谈什么、最后落在哪个判断上。引言里不要复述题干，也不要写心理学是研究行为的科学这类与题无关的开场。三四句话、一百字左右就够，把篇幅留给论证。
The introduction has three jobs: unpack the question, define the concept in psychological terms, and state the line of argument you will follow. Restating the title, or opening with a general sentence about psychology as a science, spends words on material that earns nothing. Three or four sentences are enough before the argument proper begins.
主体段落一段一个论证单元
主体段落一段只做一个论证单元：先给出这一段的判断，再用内容机制解释过程，接着用证据或真实情境支撑，最后把这一小步和概念扣上。这样一段大约五到七句。段落之间用推进关系连接，例如更深一层的问题是，而不是另外、还有这类并列堆叠。一段只描述不判断的写法，在新版评分里通常停在中低档。判断句要写得具体，能看出立场，例如这类设计只能支持相关关系，而不是这个研究很重要。论点、机制、证据、回扣概念，四步走完一段就收。
Each body paragraph should carry one unit of argument: a claim, an explanation of the mechanism, evidence or a plausible example, and an explicit link back to the concept. Five to seven sentences is the usual size. Description without a claim keeps a paragraph in the middle bands, because the mark scheme rewards building a position rather than listing what is known about a topic.
概念要贯穿全文而不是只在结尾出现
很多学生以为把概念写在结论里就算回应了题目，评分看的却是概念有没有真的把论证组织起来。做法是把概念放进三个位置：引言里点明它，主体每一段的结尾回扣它，结论里再回应它。以 causality 为例，引言说清题目关心的因果方向，主体讨论相关研究能不能支持因果、有没有混淆变量，结论说明在什么条件下这个因果说法站得住。以 measurement 为例，讨论就落在工具效度与自陈数据的偏差上。以 perspective 为例，讨论就落在不同取向对同一现象的解释差异上。概念不是标签，它是决定你选哪些素材、怎么排段落的依据。
A common assumption is that naming the concept in the conclusion is enough; in practice, markers look for a concept that organises the whole argument. The concept should appear in the introduction, at the end of each body paragraph, and again in the conclusion. With causality, for example, the introduction frames the direction of the claim, the body weighs whether the design can support it, and the conclusion states the conditions under which it holds.
评价写在哪里：分数落在批判性思维上
IB 的教师支持材料写明，Section C 不考研究细节，分数落在概念理解与批判性思维上。评价因此要往上走一层，不是样本小这类孤立的一句话，而是追问测量工具测到的是不是它声称要测的东西，样本能不能支持跨文化的结论，研究设计能不能排除其他解释。一段评价里给一个最强的质疑，再说明这个质疑对最终判断的影响有多大。很多学生以为评价就是列缺点，其实要说清缺点动摇的是哪一步推理。概念的张力也可以拿来评价，例如 responsibility 会把讨论从有没有因果推到谁该负责。段落结尾落在质疑的影响上，不要落在形容词上。
The IB teacher support material states that Section C does not assess knowledge of study details, and that conceptual understanding and critical thinking carry the marks. Evaluation therefore moves up a level: not a small sample as a standalone point, but whether the measure captures what it claims to capture, whether the sample supports a cross-cultural claim, and whether the design rules out rival explanations. One strong objection, traced through to the judgement, is worth more than a list of limitations.
研究证据的新角色：论据而不是知识点
旧版大纲的评分标准要求每个回答都用研究支撑，还要写出研究细节，新版把这条要求去掉了。研究仍然值得用，但位置变了：先讲清机制，再让研究作为例证，而不是先背研究再硬套题目。给每个研究一个具体任务，说清它支撑的是哪一句判断。常见的错误是把研究写成摘要，细节齐全却没有回答概念问题。IB 的教师支持材料说得直接，研究可以用，但研究细节不在评分范围内。所以论证的骨架必须由机制和概念撑起来，研究只是把骨架填实。
The previous curriculum required every response to be supported by studies and their details, and the new guide has dropped that requirement. Research still earns marks, but as support for an explanation rather than as the explanation itself. Give each study a job: state the point it supports before naming it, and never let a paragraph turn into a summary of the study.
四个语境各自的边界
四个语境是 health and well-being、human development、human relationships、learning and cognition。旧版里的 abnormal psychology 在新版改名为 health and well-being，另外三个语境的名称保留。语境不是装饰，它限定你能举什么例子：human relationships 里谈依恋与沟通，learning and cognition 里谈记忆与注意。题目给出哪个语境，就在那个语境的领域里取证。把别的语境的材料搬过来，读起来像在回答另一道题。很多学生以为语境只是题干的背景，其实它是评分的范围。动笔前把该语境下可用的两三个研究或情境列出来，再开始写。
The four contexts are health and well-being, human development, human relationships, and learning and cognition, with abnormal psychology renamed as health and well-being. The context fixes which examples are admissible: attachment and communication belong to human relationships, while memory and attention belong to learning and cognition. Borrowing material from a different context usually reads as an answer to a question that was not asked.
结论与立场
结论要回答命令词，并给出带条件的判断。写法是先落下判断，再补条件：在什么前提下这个说法成立，在什么前提下要打折扣。IB 的示例回答里，结论与正文论证保持一致属于高档描述的一部分。结论三四句就够，不要再引入新的论证或新的研究。常见的错误是结论写成全文摘要，读起来没有立场。把结论当成最后一段论证来写，而不是总结段。
A conclusion answers the command term and states the conditions attached to the judgement, rather than repeating the paragraphs above it. In IB sample responses, a conclusion that is consistent with the argument already made forms part of the top-band description. Three or four sentences are enough there, and no new argument should appear.
时间分配与手写长度
Paper 1 是 90 分钟答 35 分，按分值换算大约 2.5 分钟一分。Section A 的 8 分约 20 分钟，Section B 的 12 分约 30 分钟，Section C 的 15 分约 35 到 40 分钟，剩下几分钟检查。常见的错误是前两节写顺手了，Section C 只剩十分钟，论证刚开头就交卷。手写速度按每分钟 20 到 25 词估，Section C 大致能写到 600 到 800 词。进考场前按这个节奏练三次，把时间感练成习惯。表可以先画在草稿纸上：概念、语境、三段判断，各写一行。
Paper 1 gives 90 minutes for 35 marks, which works out at roughly 2.5 minutes per mark; that puts Section A near 20 minutes, Section B near 30, and Section C at 35 to 40, with a few minutes left to check. The usual error is writing comfortably through the first two sections and arriving at Section C with ten minutes left. Timed practice three times before the exam is what turns that arithmetic into a habit.
自评方法：对着评分标准给自己打分
写完一篇别只看有没有用错术语，拿 IBO 官网评分标准里的档位描述逐条对照。看四件事：命令词有没有被回答，概念解释是否准确，批判分析有没有展开，结论是否与论证一致。每篇记下最弱的一环，下一篇只针对那一环写。四个语境各写一篇限时作文，比泛泛地读十篇范文有用。写完隔一天再回读，很多当时看不见的问题会自己浮出来。找老师按官方标准给一次分，比自己估分准得多。评分标准在 IBO 官网的心理学指南与考试材料里，读原文比读二手总结可靠。
Self-assessment works best against the published markbands: check whether the command term was answered, whether the concept was explained accurately, whether critical analysis was developed, and whether the conclusion matches the argument. Note the weakest strand and target it in the next timed response, one context at a time. Four timed essays, one per context, teach more than ten essays read without marking.
SL 与 HL 的差别与 HL 拓展
SL 与 HL 考同一份 Paper 1，Section C 也是同样 15 分，差别在权重和后面的卷子。Paper 1 对 SL 占 35%，对 HL 占 25%。HL 的外部评估共 4.75 小时，Paper 1 与 Paper 2 各 1.5 小时，余下约 1.75 小时是 Paper 3，考数据分析与解释。HL 的拓展内容围绕文化、动机与技术如何塑造行为，题目里可能牵到这些主题。两类考生的长论述写法一样：概念驱动，证据服务论证，结论给判断。内部评估两边都是研究提案，24 分，占 SL 的 30%、HL 的 20%。
SL and HL sit the same Paper 1 with the same 15-mark Section C, and the difference lies in weighting and in the later papers. Paper 1 counts for 35% of the SL grade and 25% of the HL grade; HL students also sit Paper 3 on data analysis and interpretation, and their extension material covers culture, motivation and technology. The method for writing an extended response does not change between levels.
