1. Overview of the 2026 Syllabus Update | 2026 年大纲更新概览
CAIE released the new 2026–2028 syllabuses for IGCSE Sciences with the first examinations scheduled for June 2026. The update modernises content, embeds experimental skills more deeply and responds to feedback from teachers worldwide. Year 11 students in 2026 will be the first cohort to sit these refreshed papers.
剑桥国际考评部（CAIE）发布了 2026–2028 年 IGCSE 科学新大纲，首次考试定于 2026 年 6 月。本次更新在现代化内容的同时，更深入地融入了实验技能，并响应了全球教师的反馈。2026 年的 Year 11 学生将成为参加这套全新试卷的第一批考生。
The refreshed syllabuses for Biology (0610), Chemistry (0620), Physics (0625) and Coordinated Sciences (0654) retain the familiar Core and Extended tiers. However, the structure of assessment components has been revised to place practical skills at the heart of every candidate’s grade.
修订后的生物（0610）、化学（0620）、物理（0625）和协调科学（0654）大纲保留了熟悉的 Core 与 Extended 层级。然而，评估结构已进行调整，将实验技能置于每位考生成绩的核心。
2. Unified Practical Assessment | 统一的实验技能评估
The most striking structural change is the removal of the choice between Paper 5 (Practical Test) and Paper 6 (Alternative to Practical). From 2026, all candidates must take the compulsory Paper 5: Practical Skills, a written paper that tests experimental design, data handling and evaluation.
最引人注目的结构变化，是取消了在 Paper 5（实验操作考试）和 Paper 6（实验替代笔试）之间的选择。从 2026 年起，所有考生必须参加统一的必修试卷 Paper 5: Practical Skills，这份笔试考查实验设计、数据处理与评价。
Paper 5 contributes 20% of the final mark and lasts 1 hour 15 minutes. Questions are based on familiar practical contexts from the syllabus but often extend into unfamiliar scenarios, requiring candidates to demonstrate a genuine understanding of scientific investigation rather than recalling prepared experiments.
Paper 5 占总成绩的 20%，考试时长为 1 小时 15 分钟。题目基于大纲中熟悉的实验情境，但常常延伸到不熟悉的场景，要求考生展示对科学探究的真正理解，而非回忆准备好的实验。
This unified approach means that the ability to plan an experiment, identify variables, plot graphs and critically analyse results will now be assessed for every single student – no longer optional. It rewards those who engage consistently with practical work throughout the course.
这种统一模式意味着实验设计能力、变量识别、图表绘制以及对结果的批判性分析，现在将考查每一位学生——不再是可选项。那些在整个课程中持续参与实验学习的同学将从中获益。
3. Changes in Content for Physics | 物理学科内容变化
The 2026 Physics syllabus (0625) introduces a new standalone section on Space Physics. Topics include the formation of the solar system, the life cycle of stars, redshift and the expanding Universe. Calculations involving the Doppler effect and Hubble’s constant (H₀ ≈ 70 km s⁻¹ Mpc⁻¹) are now part of the extended content.
2026 年物理大纲（0625）引入了一个全新的独立章节——空间物理。主题包括太阳系的形成、恒星的生命周期、红移以及宇宙膨胀。涉及多普勒效应和哈勃常数（H₀ ≈ 70 km s⁻¹ Mpc⁻¹）的计算现在也属于 Extended 内容。
In mechanics, students will see greater emphasis on energy transfers and efficiency calculations, with real-world examples such as regenerative braking. Nuclear physics now includes more detail on fusion as an energy source on Earth, linking to sustainability themes.
在力学部分，会更加强调能量转移与效率计算，并加入再生制动等实际案例。核物理部分新增了关于地球上核聚变能源的更多细节，与可持续主题紧密相连。
Some older topics, such as detailed ray diagrams for virtual images in lenses, have been streamlined to allow room for these contemporary additions. The use of mathematical formulas remains central, with clear expectations for rearranging equations like E = mcΔθ and 1/f = 1/u + 1/v.
一些旧主题，比如透镜虚像的详细光路图，已被精简，以便为这些现代内容腾出空间。数学公式的应用仍然是核心，大纲明确要求学生能够变换如 E = mcΔθ 和 1/f = 1/u + 1/v 这样的方程。
4. Changes in Content for Chemistry | 化学学科内容变化
Environmental chemistry receives a major upgrade in the 2026 syllabus (0620). Students must now interpret carbon footprint data, evaluate methods for reducing CO₂ and CH₄ emissions, and discuss the principles of green chemistry, including atom economy in industrial processes.
环境化学在 2026 年大纲（0620）中得到了大幅升级。学生现在必须解读碳足迹数据，评估减少 CO₂ 和 CH₄ 排放的方法，并讨论绿色化学原理，包括工业流程中的原子经济性。
The topics of electrolysis and chemical cells have been reframed to include emerging technologies, such as hydrogen fuel cells and lithium-ion batteries. Learners will balance half-equations (e.g. 2H₂O → O₂ + 4H⁺ + 4e⁻) and compare different energy storage systems.
电解和化学电池主题经过了重新构建，融入了氢燃料电池、锂离子电池等新兴技术。学生将配平半反应方程式（如 2H₂O → O₂ + 4H⁺ + 4e⁻），并对不同的储能系统进行比较。
Organic chemistry has been modestly expanded to reference bioplastics and the principles of recycling polymers. The syllabus also clarifies the required depth for understanding condensation polymerisation and the hydrolysis of esters.
有机化学部分适度扩展，提及了生物塑料和聚合物回收原理。大纲还明确了对于缩合聚合反应以及酯类水解的理解深度要求。
5. Changes in Content for Biology | 生物学科内容变化
The 2026 Biology syllabus (0610) incorporates more contemporary genetics. CRISPR-Cas9 gene editing is introduced as a named example of genetic engineering, and students are expected to evaluate the ethical and social implications of gene technology.
2026 年生物大纲（0610）纳入了更多当代遗传学内容。CRISPR-Cas9 基因编辑作为基因工程的具体实例被引入，要求学生评估基因技术的伦理与社会影响。
The section on inheritance now includes coding and non-coding DNA, emphasising how mutations in regulatory regions can affect gene expression. Monohybrid cross analysis remains central, but harder pedigree diagram questions may appear in Extended papers.
遗传章节现在包括编码 DNA 与非编码 DNA，强调调控区域的突变如何影响基因表达。单基因杂交分析依然是核心，但 Extended 试卷中可能出现更具挑战性的系谱图问题。
Ecology and biodiversity topics have been updated to link directly to climate change and conservation strategies. Students should be comfortable interpreting pyramids of biomass, calculating efficiency of energy transfer (E = (energy output / energy input) × 100) and discussing the role of carbon sinks.
生态学与生物多样性主题经过更新，与气候变化和保护策略直接关联。学生应能熟练解读生物量金字塔，计算能量传递效率（E = (能量输出 / 能量输入) × 100），并讨论碳汇的作用。
6. Revised Assessment Objectives (AOs) | 评估目标调整
While the weightings of Assessment Objectives remain broadly similar – AO1 Knowledge with understanding (50%), AO2 Handling information and problem-solving (30%), AO3 Experimental skills and investigations (20%) – the way these are tested has shifted significantly.
尽管评估目标的权重基本相似——AO1 知识理解（50%）、AO2 信息处理与问题解决（30%）、AO3 实验技能与探究（20%），但这些目标的考查方式已经发生显著变化。
AO1 questions now demand more than recall; they frequently embed factual knowledge within applied contexts, such as explaining why a cactus has a thick cuticle in a specific desert scenario. AO2 rewards the ability to extract data from tables and graphs, spot anomalies and suggest explanations.
AO1 题目现在需要的已不仅仅是记忆复述；它们常常将事实知识嵌入应用情境，比如解释为什么某种仙人掌在特定沙漠环境中具有厚角质层。AO2 考查的是从表格和图表中提取数据、发现异常值并提出解释的能力。
AO3’s increased prominence means that skills like identifying sources of error, proposing improvements and using significant figures correctly will contribute more directly to the final grade than ever before.
AO3 地位的提升意味着，诸如识别误差来源、提出改进措施和正确使用有效数字等技能，将比以往更加直接地影响最终成绩。
7. Shift Towards Application and Analysis | 转向应用与分析能力
The 2026 papers display a marked trend towards questions that move information into novel situations. Instead of asking ‘What is the function of a relay?’, an Extended Physics question might describe an automatic greenhouse shading system and ask the candidate to explain the role of a relay within that circuit.
2026 年试卷展现出一个明显趋势，即把信息迁移到新颖情境中。而非问“继电器的功能是什么？”，一道 Extended 物理题可能描述一个自动温室遮阳系统，然后要求考生解释继电器在该电路中的作用。
In Chemistry, candidates might be given experimental data on the rate of reaction under different conditions and be required to deduce the order of reaction or suggest a plausible mechanism – skills that sit firmly in AO2 and AO3 territory. Biology papers increasingly ask learners to analyse epidemiological data or design a controlled experiment to test a hypothesis.
在化学中，考生可能拿到不同条件下反应速率的实验数据，需要推断反应级数或提出一个合理的机理——这些能力完全处于 AO2 和 AO3 的范畴。生物试卷越来越频繁地要求考生分析流行病学数据，或设计一个对照实验来检验假说。
This emphasis on higher-order thinking means that rote learning of mark schemes will not be sufficient. Deep conceptual understanding and the flexibility to apply that understanding are the new benchmarks for top-tier marks.
这种对高阶思维的强调意味着，仅靠背诵评分标准是远远不够的。深刻的概念理解，以及灵活应用这些理解的能力，已成为获得高分的新标杆。
8. Embedding Sustainability and Global Contexts | 融入可持续发展与全球背景
Across Physics, Chemistry and Biology, the 2026 syllabuses weave in the United Nations Sustainable Development Goals (SDGs) as recurring themes. Physics papers may discuss solar energy or the role of satellites in climate monitoring, while Chemistry addresses water purification and carbon capture.
在物理、化学和生物三科中，2026 年大纲都将联合国可持续发展目标（SDGs）作为贯穿性主题。物理试卷可能讨论太阳能或卫星在气候监测中的作用，化学则涉及水净化和碳捕集。
Biology emphasises conservation, sustainable food production and the impact of human population growth on ecosystems. Candidates are expected to use data to support arguments for or against particular policies, such as rewilding or banning single-use plastics.
生物学强调保护、可持续粮食生产以及人口增长对生态系统的影响。考生需要利用数据来支持或反驳特定政策，例如再野化或禁止一次性塑料。
These contexts are never optional extras; they form the backbone of many structured questions and can differentiate between a good answer and an excellent one that demonstrates global awareness.
这些背景知识绝非可有可无的附加项；它们构成了许多结构化问题的主干，能否展现出全球意识，往往是好答案与优秀答案的分水岭。
9. Trends in Examination Question Styles | 考试题型趋势
Several clear trends are visible in the new specimen papers and the 2026 syllabuses. A move towards ‘scenario-based’ questions that present a short narrative is now standard. These questions often span multiple assessment objectives within the same part.
在新样卷和 2026 年大纲中，可以观察到几个明确的趋势。转向以短篇叙述呈现的“基于情境”的问题已成为标配。这类问题常常在同一分题中涵盖多个评估目标。
- Data-heavy items: Tables, bar charts and line graphs are more frequent, and the data may be incomplete, requiring candidates to interpolate or extrapolate.
- 数据密集型题目：表格、条形图和折线图更为常见，且数据可能不完整，要求考生进行内插或外推。
- Open-ended justifications: ‘Explain why’ and ‘Evaluate whether’ questions reward structured, logical reasoning, often in 3–4 mark allocations.
- 开放式论述：“解释为什么”和“评价是否”的题型采用结构化的逻辑推理来得分，通常分值为 3-4 分。
- Experimental design prompts: Candidates may be asked to outline a method to investigate a given relationship, ensuring fair testing and appropriate equipment.
- 实验设计提示：考生可能被要求拟定一个探究给定关系的方法，确保公平测试并选用合适仪器。
Multiple-choice papers (Paper 1) still test recall and simple application, but the distractor options are now more subtly designed to catch out misconceptions. This rewards rigorous, precise learning and discourages guesswork based on half-remembered patterns.
选择题试卷（Paper 1）仍然考查记忆和简单应用，但干扰项的设计更为精细，旨在抓出误解。这会奖励严谨、精确的学习，并抑制基于模糊记忆模式的猜题。
10. Advice for Year 11 Students | 给 Year 11 学生的建议
Start by downloading the 2026–2028 syllabus for each science from the CAIE website. Highlight the command words – ‘describe’, ‘explain’, ‘evaluate’ – and practise writing answers that match the required depth for each. The syllabus document is your contract with the examiner.
先从 CAIE 官网下载每门科学 2026–2028 年的大纲。标出指令词——描述、解释、评价——并练习写出符合每条深度要求的答案。大纲文件就是你与考官的契约。
Because Paper 5: Practical Skills is now compulsory, integrate practical skills into your weekly revision. Practise plotting graphs with sharp lines of best fit, calculating percentage difference, and evaluating reliability. The more you familiarise yourself with common apparatus and their precision, the better.
由于 Paper 5: Practical Skills 现在是必修，请将实验技能融入每周的复习中。练习绘制带有最佳拟合线鲜明的图表，计算百分差异，以及评价可靠性。你对常用仪器及其精密度越熟悉，成绩就越好。
Build bridges between topics. If you are studying the carbon cycle in Biology, link it to combustion reactions in Chemistry and the thermodynamics of energy resources in Physics. Cross-topic connections not only deepen understanding but also mirror the integrated style of many 2026 questions.
在不同主题之间建立联系。如果你在生物学中学习碳循环，就把它与化学中的燃烧反应以及物理中的能源热力学联系起来。跨主题的联想既能加深理解，又能呼应 2026 年许多题目的综合性风格。
Finally, work through the specimen papers under timed conditions. Mark strictly using the official mark schemes, paying special attention to how marks are awarded for working, units and significant figures. Consistent practice with the new format will build the confidence needed to excel in the 2026 examinations.
最后，在限时条件下完成样卷练习。严格对照官方评分方案进行批改，特别留意步骤、单位和有效数字如何得分。持续练习新题型，将会为你在 2026 年考试中脱颖而出建立起充分的信心。
