1. Overview of the 2026 Syllabus Update | 2026年大纲更新概览
The revised syllabus, for first examination in June 2026, is designed to be more coherent, relevant and skill‑focused. While the core subject content remains rooted in fundamental principles such as atomic structure, bonding, and energetics, the way candidates are assessed is shifting. There is now a clearer emphasis on applying knowledge to unfamiliar contexts and on demonstrating scientific literacy rather than simple recall.
修订后的教学大纲（2026年6月首次考试）设计得更加连贯、贴近现实并注重技能。虽然核心学科内容仍然植根于原子结构、化学键和能量学等基本原理，但评估方式正在转变。现在更明确地强调将知识应用于陌生情境，展示科学素养，而非简单的回忆。
The syllabus document is structured around five key themes: The particulate nature of matter, Experimental techniques, Atoms, elements and compounds, Physical chemistry, and Organic chemistry. Each theme has been refined to integrate 21st‑century issues and experimental thinking from the earliest stages of study.
大纲文档围绕五个关键主题构建：物质的微粒性质、实验技术、原子、元素和化合物、物理化学以及有机化学。每个主题都经过优化，以便从学习初期就融入21世纪议题和实验思维。
2. Restructured Examination Papers | 试卷结构调整
One of the most visible changes is the streamlining of the assessment model. The Core and Extended pathways remain, but the weightings and question styles have been re‑balanced. All candidates now sit three compulsory papers, eliminating the old division between practical test and alternative‑to‑practical as entirely separate components for some learners.
最显著的变化之一是评估模式的精简。核心与扩展路径仍然保留，但权重与问题风格已经重新平衡。所有考生现在都需要参加三份必考试卷，消除了过去部分学习者将实验操作与实验替代试卷当作完全独立组成部分的划分方式。
The table below summarises the new paper structure:
下表总结了新的试卷结构：
| Paper | Core / Extended | Duration | Marks | Weighting |
|---|---|---|---|---|
| Paper 1 Multiple Choice | Core | 45 min | 40 | 30% |
| Paper 2 Multiple Choice | Extended | 45 min | 40 | 30% |
| Paper 3 Theory | Core | 1 h 15 min | 80 | 50% |
| Paper 4 Theory | Extended | 1 h 15 min | 80 | 50% |
| Paper 5 Practical Skills | Both pathways | 1 h 15 min | 40 | 20% |
Notice that Paper 5 is now a single practical‑skills examination for all candidates, combining elements of investigation planning, data handling and evaluation. This change makes practical work an integral part of every student's grade.
请注意，新Paper 5现在是一份面向所有考生的统一实验技能考试，融合了探究规划、数据处理和评价等要素。这一变化使实验操作成为每位学生成绩的组成部分。
3. New Content Areas Added to the Syllabus | 新增内容领域
The 2026 syllabus incorporates several contemporary topics that were previously absent or only hinted at. These additions reflect advances in materials science, environmental chemistry and everyday applications. For instance, candidates now need to understand the principles of green chemistry, including atom economy calculations in greater depth, and the role of catalysts in sustainable processes.
2026年大纲纳入了几个以前没有或仅略有涉及的当代主题。这些新增内容反映了材料科学、环境化学以及日常应用方面的进展。例如，考生现在需要深入理解绿色化学原理，包括更详细地计算原子经济性，以及催化剂在可持续工艺中的作用。
Other new topics include: nanochemistry and the properties of nanoparticles, different types of batteries and fuel cells (including lithium‑ion and hydrogen fuel cells), and the chemistry of polymers with an emphasis on biodegradable and recycling pathways. These topics extend the traditional organic and physical chemistry sections, making the course more relevant to current technological and environmental challenges.
其他新增主题包括：纳米化学与纳米颗粒的性质，不同类型电池与燃料电池（包括锂离子电池和氢燃料电池），以及侧重可生物降解和回收途径的聚合物化学。这些主题拓展了传统的有机与物理化学部分，使课程与当前技术和环境挑战更加紧密相连。
4. Content That Has Been Removed or Reduced | 删减或弱化的内容
To make room for new material and a deeper focus on skills, some legacy topics have been trimmed. For example, detailed industrial processes such as the Haber process and Contact process are still studied, but the emphasis has shifted from memorising flow diagrams to interpreting process conditions using principles of equilibrium and rate. Similarly, the extraction of certain metals, like aluminium, now focuses more on the underlying electrochemistry than on historical methods.
为了给新材料和更深入的技能聚焦腾出空间，一些遗留课题已经被精简。例如，像哈伯法和接触法这样的详细工业过程仍需学习，但重点已经从记忆流程图转向利用平衡和速率原理解释工艺条件。同样，某些金属的提炼（如铝）现在更侧重于背后的电化学原理，而非历史方法。
Additionally, the memorisation of specific flame tests for a long list of cations has been reduced; instead, candidates are expected to understand the principles of spectroscopic identification and interpret simple emission spectra. This shift rewards conceptual understanding over rote learning.
此外，对一长串阳离子进行特定焰色试验的记忆要求已经降低；取而代之的是，考生需要理解光谱鉴定原理，并能解释简单的发射光谱。这一转变奖励概念性理解，而非死记硬背。
5. Enhanced Focus on Practical Skills | 对实验技能的高度重视
The introduction of a unified Paper 5 Practical Skills for all candidates is perhaps the most significant structural change. This paper does not require a specific set of prescribed experiments; rather, it tests the ability to plan investigations, select apparatus, record and process data, draw conclusions and evaluate methods. Familiarity with common laboratory techniques—titration, filtration, chromatography, measuring rate of reaction—is essential, but the questions are framed around novel scenarios.
面向所有考生引入统一的Paper 5实验技能考试或许是最重大的结构变化。该试卷不要求具体的指定实验，而是考查规划探究、选择仪器、记录和处理数据、得出结论以及评价方法的能力。熟悉常见的实验室技术——滴定、过滤、色谱、测量反应速率——至关重要，但问题均围绕新颖情境设问。
Year 9 students should begin developing these investigative skills early. Regular hands‑on experimentation, even with simple apparatus, builds the confidence to handle variables, identify anomalies and suggest improvements—all of which are now explicitly assessed. The syllabus also expects learners to link experimental outcomes to the theoretical models studied in class.
Year 9学生应尽早开始培养这些探究技能。定期的动手实验，即使使用简单的仪器，也能建立处理变量、识别异常数据并提出改进措施的信心——这些都是现在明确考查的能力。大纲还期望学习者将实验结果与课堂所学的理论模型联系起来。
6. Mathematics and Data Handling Requirements | 数学与数据处理要求
ematical competence. While the mathematical level remains within reach of a typical Year 9– lar calculations using the formula n = m ÷ M, and gas volume conversions under standard conditions. Graphical skills are also tested more rigorously: plotting data, determining gradients, and interpreting intercepts now feature in both theory and practical papers.
新大纲提高了数学能力的要求。虽然数学水平仍处于典型 Year 9–10 学生可及范围内，但计算的范围和频次都有所增加。考生必须熟练掌握比例、百分比产率、运用公式 n = m ÷ M 的摩尔计算，以及标准条件下的气体体积换算。图形技能也考查得更加严格：绘制数据图、确定斜率、解释截距等内容现在同时出现在理论卷和实验卷中。
A typical mathematical question might ask: "Calculate the mass of water produced when 4.0 g of hydrogen burns completely in oxygen." king steps involve converting mass to moles, using the mole ratio, and then converting back to mass. Such problems will be common.
一个典型的数学问题可能会问：“计算 4.0 g 氢气完全在氧气中燃烧时生成的水的质量。”方程是 2H₂ + O₂ → 2H₂O。解题步骤包括将质量转换为物质的量、利用摩尔比，然后再转换回质量。此类问题将普遍出现。
n = m / M and volume of gas = n × 24 dm³ mol⁻¹ (at r.t.p.)
Key formulas like these must be at students' fingertips, along with the ability to choose the correct one under exam pressure.
像这样的关键公式必须让学生烂熟于心，并且能够在考试压力下正确选用。
7. Emphasis on Environmental and Sustainable Chemistry | 对环境与可持续化学的强调
The 2026 syllabus weaves sustainability into nearly every topic. From the start, students explore the carbon cycle, greenhouse gases and climate change, but now they also study carbon footprinting, life‑cycle analysis of materials, and the principles of a circular economy. In organic chemistry, the production of biofuels, bioplastics and the catalytic cracking of waste polymers are examined in practical, real‑world contexts.
2026年大纲将可持续性编织进了几乎每一个课题。从一开始，学生就探究碳循环、温室气体和气候变化，而现在他们还要学习碳足迹、材料的生命周期分析以及循环经济原则。在有机化学中，生物燃料、生物塑料的生产以及废旧聚合物的催化裂化都在真实世界的实际情境中加以考查。
This trend mirrors the global push towards greener technologies and aligns with UN Sustainable Development Goals. For students, it means learning chemistry not merely as a set of facts, but as a tool for solving pressing environmental problems. Exam questions will often present data about emissions or energy efficiency and ask candidates to propose improvements or evaluate a process from a sustainability standpoint.
这一趋势反映了全球对绿色技术的推动，并与联合国可持续发展目标保持一致。对于学生而言，这意味着学习化学不仅仅是一组事实，而是一种解决紧迫环境问题的工具。考试题目往往会呈现有关排放或能源效率的数据，要求考生从可持续性角度提出改进建议或评价某个工艺。
8. Updated Assessment Objectives (AO1, AO2, AO3) | 评估目标（AO1、AO2、AO3）的更新
The weighting of assessment objectives has been subtly rebalanced to reduce the dominance of pure recall. While AO1 (Knowledge with understanding) still forms a significant part, it now typically accounts for about 40% of the marks rather than 50%. AO2 (Handling information and problem solving) has grown to approximately 35%, and AO3 (Experimental skills and investigations) now carries around 25%. This means that students who only memorise notes without practising application and analysis will find it harder to achieve top grades.
评估目标的权重已经悄然重新平衡，以降低单纯回忆的主导地位。虽然AO1（知识理解）仍占重要部分，但现在通常约占40%的分数，而非50%。AO2（信息处理与问题解决）已增至约35%，而AO3（实验技能与探究）现在约占25%。这意味着，只背诵笔记而不练习应用和分析的学生将更难获得高分。
In practice, this translates into more questions that begin with an unfamiliar diagram, a table of data or a short experimental description. Learners need to infer chemical principles from the information provided, rather than regurgitating a textbook definition. Year 9 students should start building this habit of explaining 'why' and 'how', not just 'what'.
实际上，这转化为更多以陌生图表、数据表格或简短实验描述开头的题目。学习者需要根据提供的信息推断化学原理，而非复述教科书定义。Year 9学生应开始养成解释“为何”和“如何”的习惯，而不仅仅是“是什么”。
9. Bridging Core and Extended Pathways | 核心与扩展路径的衔接
The distinction between Core and Extended tiers remains, but the overlap has been made more transparent. Core content forms the foundation; Extended material adds depth and additional topics. In the 2026 syllabus, many of the new environmental and materials topics appear only in the Extended curriculum. Students aiming for grades A* to B must therefore engage with advanced concepts such as electrode potentials, equilibrium constants in qualitative terms, and more complex organic reaction pathways.
核心与扩展级别的区分依然存在，但重叠部分变得更加透明。核心内容奠定基础；扩展材料则增加深度和额外课题。在2026年大纲中，许多新的环境和材料课题仅出现在扩展课程中。因此，目标A*至B成绩的学生必须学习电极电势（定性术语）、平衡常数以及更复杂有机反应路径等高级概念。
For a Year 9 student, the decision between Core and Extended is usually made in Year 11, but the groundwork is laid early. Teachers will often introduce Extended concepts gradually, even in general classes. Understanding the syllabus progression helps students gauge early on whether they have the interest and aptitude for the Extended pathway.
对于Year 9学生，核心与扩展的选择通常在Year 11才做出，但基础很早就开始铺垫。教师往往会在普通课堂中逐步引入扩展概念。了解大纲的递进顺序有助于学生及早判断自己是否具备学习扩展路径的兴趣和能力。
10. Grade Descriptors and Expected Performance | 等级描述与预期表现
Cambridge has revised the grade descriptors for Chemistry to align with the new assessment objectives. For a Grade C, a candidate must demonstrate a good knowledge of core chemical principles, interpret simple data, and carry out straightforward experiments with guidance. For a Grade A, a candidate is expected to apply concepts to novel problems, critically evaluate experimental designs, and communicate chemical ideas using precise terminology and equations.
剑桥已修订了化学科的成绩等级描述，以与新的评估目标保持一致。对于C级，考生必须展示对核心化学原理的良好掌握，能解释简单数据，并在指导下开展直接的实验。对于A级，考生则应能将概念应用于新问题，批判性地评价实验设计，并使用精确术语和方程式交流化学思想。
These descriptors are useful for self‑assessment. A Year 9 learner can start using them to review their own understanding after each topic. For instance, after studying the mole concept, ask: "Can I explain the mole in terms of Avogadro's constant, calculate molar masses from the Periodic Table, and apply the concept to titration results?" This reflective approach builds confidence and direction.
这些描述对自我评估很有用。Year 9学习者可以开始运用它们在每个课题后回顾自己的理解。例如，学习完摩尔概念后，问自己：“我能用阿伏伽德罗常数解释摩尔，根据元素周期表计算摩尔质量，并将此概念应用于滴定结果吗？”这种反思式方法能够建立信心和方向感。
11. Common Misconceptions and How the Syllabus Addresses Them | 常见误解及大纲如何应对
Certain misconceptions have historically plagued IGCSE Chemistry students: confusing the terms 'atom' and 'molecule', equating heat and temperature in exothermic reactions, or believing that a catalyst lowers the activation energy by providing energy. The 2026 syllabus tackles these head‑on by introducing particle‑level diagrams and modelling activities early. It stresses that a catalyst provides an alternative pathway with lower activation energy, not extra energy.
某些误解历来困扰IGCSE化学学生：混淆“原子”和“分子”这两个术语，在放热反应中将热量与温度等同起来，或者认为催化剂通过提供能量来降低活化能。2026年大纲通过早期引入粒子层次图示和建模活动，直面这些问题。它强调催化剂是提供一条活化能较低的替代路径，而不是提供额外能量。
Also, the concept of ionic bonding as a 'transfer' of electrons often leads students to view ionic compounds as discrete pairs. The syllabus now encourages using a lattice model and physical properties from the start, helping learners see ionic bonding as an extended electrostatic attraction. Such pedagogical shifts reduce deeply embedded errors and prepare students better for advanced study.
同样，将离子键视为电子“转移”的概念常常导致学生将离子化合物视为离散的离子对。大纲现在鼓励从一开始就使用晶格模型和物理性质进行教学，帮助学习者将离子键理解为扩展的静电吸引。这些教学转变减少了根深蒂固的错误，并为学生进阶学习做好了更充分的准备。
12. Recommended Study Strategies for Year 9 | Year 9 推荐学习策略
Against this backdrop of change, Year 9 students should focus on building a robust foundation. Start by mastering the first three themes thoroughly: states of matter, basic experimental techniques, and atomic structure. Use the syllabus as a checklist, not just a textbook. Regularly practise drawing and labelling diagrams, balancing equations, and performing simple mole calculations.
在这种变化的背景下，Year 9学生应专注于构建扎实的基础。首先要彻底掌握前三个主题：物质状态、基本实验技术和原子结构。将大纲用作检查清单，而不仅仅是教科书。定期练习绘制和标注图表、配平方程式以及进行简单的摩尔计算。
Incorporate active recall: instead of simply reading notes, test yourself with past‑paper questions adapted for your level. Even if you haven't covered all the content, attempting simplified versions of exam questions builds familiarity with command words such as 'describe', 'explain', 'predict', and 'evaluate'. Pair this with practical work at home or in the school laboratory; video demonstrations can supplement where equipment is limited.
融入主动回忆法：不要只阅读笔记，要用适合自己水平的历年真题进行自测。即便尚未学完所有内容，尝试做简化的考题版本也能熟悉“描述”、“解释”、“预测”和“评价”等指令词。在家或学校实验室辅以动手实践；当设备有限时，视频演示可以作为补充。
