📚 Year 12 CIE Physics: Exam Changes and Trends for 2026 | 2026年CIE物理考试变化与趋势
From 2025 onwards, CIE AS Level Physics (9702) follows a refreshed syllabus designed to deepen conceptual understanding and strengthen practical skills. As we move into 2026 – the second year of this syllabus – students can look to the first exam series for clues about examiner expectations and emerging question trends. This article unpacks the key structural changes, updated assessment objectives, content shifts, and what Year 12 learners should focus on to excel in the 2026 exams.
从2025年起，CIE AS物理（9702）启用了更新版大纲，旨在深化概念理解并加强实验技能。进入2026年——新大纲实施的第二年——学生可以借鉴首次考试的命题规律来把握评分员的期待与出题趋势。本文梳理了核心结构变化、评估目标更新、内容调整，以及12年级学生备战2026年考试时需要抓住的重点。
1. The 2025–2027 Syllabus: A New Era for AS Physics | 2025–2027大纲：AS物理新纪元
The 2025–2027 syllabus, first examined in 2025, replaces the previous 2022–2024 version. It is not a radical overhaul but a careful refinement that aligns with modern physics teaching. The syllabus document itself is clearer, with learning outcomes more precisely worded and practical skills embedded more explicitly into theory topics.
2025–2027年大纲于2025年首次考试，取代了此前的2022–2024版本。它并非推倒重来，而是一次精细的调整，与现代物理教学对齐。新大纲文件本身更加清晰，学习成果表述更精确，并且实验技能更明确地融入了理论主题。
For Year 12 students in 2026, this means that while the topics feel familiar, the depth of treatment and the style of assessment have evolved. Understanding the ‘spirit’ of the new syllabus is the first step toward achieving top grades.
对于2026年的12年级学生来说，这意味着虽然主题看起来很熟悉，但处理深度和评估风格已经发生了变化。领会新大纲的“精神”是迈向高分的第一步。
2. Unchanged Exam Structure with Subtle Shifts | 考试结构不变，暗藏变化
At first glance, the AS exam structure looks identical: Paper 1 (Multiple Choice, 1h 15min, 40 marks), Paper 2 (Structured Questions, 1h 15min, 60 marks), and Paper 3 (Advanced Practical Skills, 2h, 40 marks). The weightings also remain the same – 31%, 46%, and 23% respectively. However, the nature of questions within these papers is shifting.
乍一看，AS考试结构没变：卷1（选择题，1小时15分钟，40分）、卷2（结构化问题，1小时15分钟，60分）、卷3（高级实验技能，2小时，40分）。权重也保持不变——分别为31%、46%和23%。然而，这些试卷中题目的性质正在发生变化。
Paper 1 now includes more questions that require two-step reasoning or data interpretation, moving away from simple recall. Paper 2 increasingly presents unfamiliar contexts where students must apply core principles. Paper 3 continues to focus on practical skills, but its marking criteria have been tightened to reward precision and thorough evaluation.
卷1现在包含更多需要两步推理或数据解读的题目，而非简单回忆。卷2越来越多地呈现陌生情境，要求学生运用核心原理。卷3仍聚焦于实验技能，但其评分标准已收紧，以奖励操作的精确性和全面的评估。
3. Content Adjustments: What’s In and What’s Out | 内容调整：新增与删减
The new syllabus removes some outdated examples and introduces subtle but important additions. For instance, the treatment of uncertainties has been strengthened, with a greater focus on absolute, fractional, and percentage uncertainties, as well as combining uncertainties through propagation rules. Students must now be confident in distinguishing between systematic and random errors in varied experimental scenarios.
新大纲删除了一些过时的例子，同时引入了细微但重要的补充。例如，对不确定度的处理得到了加强，更注重绝对不确定度、相对不确定度和百分不确定度，以及通过传播规则合成不确定度。学生现在必须能够自信地在各种实验场景中区分系统误差和随机误差。
Additionally, there is a renewed emphasis on modern applications of electricity and waves. Superposition and stationary waves now include more explicit links to musical instruments and communication technologies, while the particle physics section receives updated terminology to reflect current scientific consensus.
此外，对电学和波动的现代应用重新进行了强调。叠加和驻波现在更明确地联系乐器与通信技术，而粒子物理部分则使用了更新的术语以反映当前的科学共识。
4. Greater Emphasis on Practical Skills and Paper 3 | 更强调实验技能与卷3
Perhaps the most significant shift is the increased weighting of experimental skills across the entire AS qualification. The assessment objective AO3 (Experimental skills and investigations) now carries 30% of the marks, up from 20% in the previous syllabus. While Paper 3 directly assesses these skills, AO3 also appears in data-analysis questions on Papers 1 and 2.
或许最显著的变化是实验技能在整个AS考试中权重的增加。评估目标AO3（实验技能与探究）现在占总分的30%，而旧大纲中为20%。虽然卷3直接考查这些技能，但AO3也出现在卷1和卷2的数据分析题中。
In Paper 3, examiners now expect students to not only collect data accurately but also to justify their choices of apparatus, suggest improvements to reduce uncertainty, and critically evaluate their own graphs. Tables must follow strict conventions: quantities with units in headings, consistent significant figures, and clear distinction between raw and calculated data.
在卷3中，评分员现在期望学生不仅能准确收集数据，还要能说明器材选择的理由、提出减少不确定度的改进措施，并能批判性地评估自己的图线。表格必须遵循严格的规范：表头中写清物理量及单位、有效数字前后一致，并且清楚地区分原始数据与计算数据。
5. Updated Assessment Objectives and Weightings | 评估目标与权重更新
The revised distribution of assessment objectives is a game-changer. AO1 (Knowledge and understanding) has been reduced from 40% to 30%, while AO2 (Handling, applying, and evaluating information) holds at 40%, and AO3 rises to 30%. This signals a deliberate move away from rote memorisation toward analytical thinking.
修订后的评估目标分布是一个变革。AO1（知识与理解）从40%降至30%，而AO2（处理、应用和评估信息）保持在40%，AO3升至30%。这表明有意从死记硬背转向分析性思维。
| Assessment Objective | Old Weight (2022–2024) | New Weight (2025–2027) |
|---|---|---|
| AO1 Knowledge with understanding | 40% | 30% |
| AO2 Handling information and problem solving | 40% | 40% |
| AO3 Experimental skills and investigations | 20% | 30% |
For Year 12 students, this means that simply recalling definitions and laws will not be enough. You must practise explaining why a physical relationship holds, how a model breaks down at limits, and what assumptions underlie a derivation. These higher-order skills are now the main route to top marks.
对12年级学生而言，这意味着仅仅背诵定义和定律是不够的。你必须练习解释物理关系为何成立、模型在极限条件下如何失效，以及推导建立在哪些假设之上。这些高阶技能现在是冲刺高分的主要途径。
6. The New Formula Sheet and Data Booklet | 新版公式与数据手册
The 2025 syllabus introduces an updated formula sheet that accompanies Papers 1 and 2. While most core equations remain the same, there are a few notable additions. For example, the equation for the photoelectric effect now appears as hf = φ + Eₖ ₘₐₓ, and the de Broglie wavelength equation λ = h / p is included. These additions reflect the growing importance of quantum ideas in the AS curriculum.
2025年大纲引入了更新的公式表，随卷1和卷2一同提供。虽然大多数核心公式保持不变，但有几项值得注意的添加。例如，光电效应方程现在列为hf = φ + Eₖ ₘₐₓ，而德布罗意波长公式λ = h / p也被添加进去。这些增添反映了量子概念在AS课程中日益重要。
The data booklet also now includes more precise values for constants like the Planck constant and elementary charge, aligned with the latest CODATA adjustments. Students should familiarise themselves with the exact formats used in the booklet, as misreading a formula during the exam can cost valuable marks. Crucially, memorising equations is no longer a significant advantage; using them appropriately in context is what matters now.
数据手册现在还包括了更精确的常数值，如普朗克常数和基本电荷，与最新的CODATA调整保持一致。学生应熟悉手册中使用的确切格式，因为在考试中误读公式会丢失宝贵的分数。关键的是，记忆方程不再是一个显著优势；在具体情境中恰当地运用它们才是现在的关键。
7. Trends in Multiple Choice Questions (Paper 1) | 选择题（卷1）的命题趋势
Analysis of the 2025 Paper 1 reveals several clear trends that will likely continue in 2026. First, there are fewer standalone ‘definition’ questions. Instead, a typical question may give a short scenario involving two forces, a graph, or a circuit diagram, then ask for the resulting acceleration, potential difference, or energy change. This tests AO2 even in a multiple-choice format.
对2025年卷1的分析揭示了几个很可能延续到2026年的明显趋势。首先，独立的“定义”题变少了。取而代之的是，一个典型问题可能给出包含两个力、一张图或一个电路图的简短情境，然后询问由此产生的加速度、电势差或能量变化。即使是在选择题形式下，这也考查了AO2。
Second, graph-based MCQs have become more prevalent. Questions showing v–t, F–x, or I–V graphs require students to extract gradients, areas, or intercepts and interpret their physical significance within seconds. Third, increasing numbers of questions embed experimental error analysis – for example, asking which change would reduce the percentage uncertainty in a derived quantity.
其次，基于图像的选择题变得更加普遍。展示v–t、F–x或I–V图的问题要求学生提取斜率、面积或截距，并在数秒内解读其物理意义。第三，越来越多的题目融入了实验误差分析——例如，询问哪种变化能减小导出量的百分不确定度。
8. Structured Questions (Paper 2): Deeper Integration | 卷2结构化问题：更深入整合
Paper 2 has always been the main differentiator, and the new syllabus intensifies this. In 2026, expect questions that weave together multiple topics within a single context. For example, a mechanics question might begin with dynamics, lead into energy conservation, then finish with a materials-based extension asking about the elastic limit and plastic deformation of a safety rope.
卷2一向是拉开差距的关键，而新大纲进一步加剧了这一趋势。在2026年，可以预期在一段情境中交织多个主题的题目。例如，一道力学题可能从动力学开始，转入能量守恒，最后以基于材料的拓展结束，询问安全绳的弹性极限和塑性形变。
The ‘show that’ type question remains common, requiring students to derive a given expression from first principles or from provided data. Mark schemes now demand clear, logical steps: omitting a crucial substitution or failing to state an assumption can lose marks. Students must practise writing concise yet complete solutions, as examiners will penalise sloppy reasoning even if the final answer is correct.
“证明”类型的题目依然常见，要求学生从基本原理或给定数据出发推导出某个表达式。目前的评分方案要求呈现清晰、合乎逻辑的步骤：省略一个关键的代入或未能陈述假设都会失分。学生必须练习写出简洁又完整的解答，因为即使最终答案正确，草率的推理也会受到惩罚。
9. Graph and Data Analysis Skills on the Rise | 图表与数据分析技能日益重要
Both Papers 2 and 3 now feature more extensive graph-plotting and interpretation exercises. In Paper 2, you might be given a sketch of an I–V characteristic for a filament lamp and asked to explain its shape in terms of energy dissipation and temperature dependence of resistance, linking to the equation R = V / I and the power law P = I²R.
如今，卷2和卷3都出现了更广泛的绘图与解读练习。在卷2中，可能会给出一个灯丝的I–V特性草图，要求你用能量耗散和电阻的温度依赖性解释其形状，并联系方程R = V / I和功率定律P = I²R。
In Paper 3, students are frequently asked to linearise a relationship – for instance, plotting T² against l for a simple pendulum – and then to calculate g from the gradient. The new mark schemes explicitly reward correct axis labels with units, sensible scales that occupy more than half the grid, and accurate plotting to within half a small square. After drawing the line of best fit, candidates must be able to identify and possibly reject anomalous points with clear justification.
在卷3中，学生经常被要求对某个关系进行线性化处理——例如，对单摆绘制T²-l图——然后通过斜率计算g。新的评分方案明确奖励：带单位的坐标轴标签、占据网格超过一半的合理刻度，以及精确到半个小方格以内的描点。在画出最佳拟合线后，考生必须能够识别并可能剔除异常点，并给出明确的理由。
10. Command Words and Marking Precision | 指令词与评分精确度
The CIE physics mark schemes now apply command words with sharper precision. Words like ‘state’, ‘describe’, ‘explain’, ‘suggest’, and ‘deduce’ carry distinct expectations. For example, ‘explain’ demands a cause-and-effect reasoning chain, often linking a fundamental principle to the observed phenomenon. ‘Suggest’ calls for application of physics knowledge to a novel situation, where there may be more than one valid answer but the justification is crucial.
CIE物理的评分方案现在对指令词的运用更加精准。像“陈述”“描述”“解释”“建议”和“推断”等词语有着明确的预期。例如，“解释”要求因果推理链，通常将基本原理与观察到的现象联系起来。“建议”则要求将物理知识应用于新情境，可能会有多个有效答案，但论证过程至关重要。
In 2026, students should pay close attention to the number of marks allocated. A three-mark ‘explain’ question likely expects three distinct points in a logical sequence. Practice with past papers from 2025 will help you internalise the expected depth for each command word, avoiding the common pitfall of writing too much irrelevant detail while missing the specific scientific argument.
在2026年，学生应密切关注分配的分数值。一个三分的“解释”题往往期待一个逻辑序列中的三个明确要点。使用2025年真题进行练习，将帮助你内化每个指令词所要求的深度，避免陷入写了许多无关细节却遗漏了具体科学论证的常见陷阱。
11. Lessons from the 2025 Exam Series | 2025年首次考试的经验教训
The first sitting of the new syllabus in 2025 provided invaluable insights. Examiner reports highlighted that many candidates lose marks not through ignorance but through poor exam technique. Common issues included: not reading the question stem carefully enough and answering a slightly different question, using inappropriate significant figures in final numerical answers, and leaving ‘show that’ derivations incomplete because a step was skipped.
2025年新大纲的首次考试提供了宝贵的洞见。考官报告指出，许多考生失分并非因为无知，而是由于糟糕的考试技巧。常见问题包括：没有足够仔细地阅读题干，导致回答了稍有偏差的问题；在最终数值答案中使用了不恰当的有效数字；以及因为跳过了某个步骤而未能完成“证明”题的推导。
Another clear trend was that students who performed best on Paper 2 were those who could smoothly switch between algebraic manipulation and numerical substitution. They also used annotated diagrams to support their explanations, which examiners rewarded as evidence of clear thinking. For Paper 3, the top candidates drew tables before starting to take readings, planned their ranges to cover the maximum safe spread, and immediately checked for consistency – habits that save time and improve accuracy.
另一个明显趋势是，卷2表现最好的学生是那些能流畅地在代数处理和数值代入之间切换的人。他们还使用了带注释的图解来辅助说明，评分员将此视为清晰思维的证明并给予奖励。对于卷3，顶尖考生在开始读数之前就画好表格，规划测量范围以覆盖最大安全跨度，并立即检查一致性——这些习惯既节省时间又提高了准确性。
12. How to Prepare for AS Physics in 2026 | 如何备战2026年AS物理
Given these changes and trends, a strategic approach is essential. Begin by obtaining the official 2025–2027 syllabus document from the Cambridge website and cross-referencing it with your class notes – make sure no updated learning outcome has been overlooked. Next, integrate regular practical work into your revision: even if you don’t have a full lab, simulating experiments with online interactives and analysing the data as you would for Paper 3 builds confident AO3 skills.
鉴于这些变化与趋势，战略性方法必不可少。首先，从剑桥官网获取官方2025–2027大纲文件，并与你的课堂笔记交叉对比——确保没有遗漏任何更新的学习成果。其次，将定期的实验练习融入复习：即使没有完整实验室，通过在线互动模拟实验并按照卷3的要求分析数据，也能建立起自信的AO3技能。
For theory, replace passive reading with active recall. After studying a topic like forces, write down all the key equations with their conditions of validity without looking, then solve a previous Paper 2 question under timed conditions. Pay special attention to experimental-awareness questions that ask you to suggest a method to measure the Young modulus of a wire, including a diagram of the set-up and identification of the variables you would keep constant.
对于理论学习，用主动回忆取代被动阅读。在学习诸如力这样的主题后，合上书写下所有关键方程及其适用条件，然后在限时条件下解决一道往年的卷2题目。要特别注意那些“实验意识”类问题，它们会要求你提出测量金属丝杨氏模量的方法，包括装置示意图并指出需要保持恒定的变量。
Finally, learn the command-word language. Create a glossary with examples for ‘describe’, ‘explain’, ‘suggest’, and ‘determine’. Practice writing answers that are precisely pegged to the mark allocation, and ask your teacher to critique your reasoning. The 2026 exam will reward clarity, precision, and genuine understanding – and that is a trend you can start following today.
最后，掌握指令词的语言。为“描述”“解释”“建议”和“确定”创建附带示例的术语表。练习写出与分值精确匹配的答案，并请老师点评你的推理过程。2026年的考试将奖励清晰、精确和真正的理解——而这是今天就可以开始追随的趋势。
