从2026年起，剑桥IGCSE化学（0620）将采用更新的教学大纲进行考试。新大纲体现了现代教学理念和全球科学教育趋势。本文以中英双语形式，详细分解评估目标、核心内容、实验技能和考试形式的主要变化。无论你是学生还是教师，理解这些变化对备考成功至关重要。
1. Overview of the 2026 Syllabus Update | 2026年教学大纲更新概述
The 2026 syllabus for Cambridge IGCSE Chemistry represents the first major revision since the 2023–2025 cycle. While the subject code 0620 remains unchanged, the curriculum places greater emphasis on conceptual understanding and the application of knowledge, rather than rote memorisation.
2026年剑桥IGCSE化学教学大纲是自2023–2025周期以来的首次重大修订。尽管科目代码0620保持不变，课程更加强调概念理解和知识应用，而不是机械记忆。
Assessment weightings have been recalibrated to reward analytical thinking. The updated syllabus introduces more synoptic questions that require students to link topics across physical, inorganic, and organic chemistry. Time allocation for each paper remains similar, but the nature of tasks has evolved to build real-world problem-solving skills.
评估权重经过重新调整，鼓励分析性思维。更新后的大纲引入了更多综合性题目，要求学生将物理化学、无机化学和有机化学的主题联系起来。每份试卷的时间分配基本不变，但任务性质已转变为培养解决实际问题的能力。
The syllabus now includes clearly defined ‘key concepts’ that act as unifying threads across all topics. These are: Atoms and molecules, Bonding and structure, Energy changes, Rates of reaction, and Chemical analysis. These threads are explicitly assessed in the new exam papers.
新大纲包含明确定义的“核心概念”，这些概念贯穿所有主题，包括：原子与分子、键合与结构、能量变化、反应速率以及化学分析。这些主线在最新试卷中会被明确考查。
2. Changes in Assessment Objectives | 评估目标的变化
Cambridge has revised the assessment objectives (AOs) to better reflect current educational standards. AO1 Knowledge with understanding now accounts for approximately 40% of the total marks, down from 50%. AO2 Handling information and problem-solving has increased to 40%, and AO3 Experimental skills and investigations remains at 20%.
剑桥更新了评估目标，以更好地反映当前教育标准。AO1（知识与理解）现在占总分的约40%，低于此前的50%。AO2（信息处理与问题解决）提升至40%，AO3（实验技能与探究）保持20%不变。
This shift means that simply recalling facts will no longer be sufficient to achieve top grades. Students must be able to interpret unfamiliar data, extract relevant information from graphs and tables, and propose logical solutions to novel chemical problems. For instance, a question might provide the boiling points of unknown alkanes and ask learners to deduce their molecular formulas.
这一转变意味着仅靠回忆事实不足以获得高分。学生必须能够解读陌生数据，从图表中提取相关信息，并为新颖的化学问题提出合理的解决方案。例如，题目可能给出未知烷烃的沸点，要求学生推断其分子式。
Practical skills are now assessed more rigorously in the written papers, not just in the alternative to practical or the practical test. Core experimental techniques such as titration, chromatography, and salt preparation appear in Paper 4 (Theory Extended), demanding that students explain procedural steps and justify choices of apparatus.
实验技能现在在笔试中得到更严格的评估，而不仅仅是在替代实验或实验操作考试中。核心实验技术如滴定、色谱法和盐的制备出现在Paper 4（理论拓展卷）中，要求学生解释实验步骤并证明仪器选择的合理性。
3. Enhanced Practical Skills Emphasis | 实验技能强化
The 2026 syllabus strengthens the link between theory and laboratory practice. Every topic now includes compulsory experimental work, and the revised syllabus document provides a detailed list of suggested practical activities. Teachers are expected to integrate these investigations into lessons to foster hands-on understanding.
2026年教学大纲强化了理论与实验的联系。每个主题现在都包含必修的实验活动，修订后的大纲文件提供了详细的建议实践清单。教师需要将这些探究融入课堂，以培养动手理解能力。
In Paper 6 (Alternative to Practical), there is a new focus on error analysis and improvements. Rather than merely describing steps, candidates must identify sources of systematic and random errors, suggest realistic modifications, and evaluate the reliability of results. For example, after reading a description of an enthalpy change experiment using simple calorimetry, a student might be asked to calculate percentage error and recommend a more accurate apparatus.
在Paper 6（实验替代卷）中，新增了对误差分析与改进的关注。考生不能仅仅描述步骤，还需要识别系统误差和随机误差的来源，提出可行的修改建议，并评估结果的可靠性。例如，在阅读使用简易量热法测定焓变的实验描述后，学生可能会被要求计算百分误差并推荐更精确的仪器。
Furthermore, safety considerations have been integrated more explicitly. Students must know standard laboratory hazard symbols, understand the precautions necessary when handling concentrated acids or flammable gases, and be ready to write concise risk assessments. This aligns with the growing global emphasis on laboratory safety culture.
此外，安全意识也被更明确地纳入考核。学生必须了解标准实验室危险标志，明白操作浓酸或易燃气体时需要的预防措施，并能够撰写简洁的风险评估。这与全球对实验室安全文化日益增长的重视相吻合。
4. Mathematics in Chemistry | 化学中的数学要求
Mathematical literacy is now a more prominent component of Cambridge IGCSE Chemistry. While the required mathematical skills remain broadly at the Key Stage 3/4 level, the frequency and complexity of calculations have increased. Students can expect more multi-step problems involving mole concept, concentration, gas volumes, and energy changes.
数学素养现在成为剑桥IGCSE化学更突出的组成部分。尽管所需的数学技能基本保持在中学阶段水平，但计算的频率和复杂性有所提高。学生将遇到更多涉及摩尔概念、浓度、气体体积和能量变化的多步骤问题。
The syllabus explicitly lists essential mathematical competencies: use of significant figures, proportional reasoning, rearranging formulae, interpreting slopes of graphs, and calculating percentage yield. A typical question might require a student to determine the empirical formula of a compound from percentage composition data, then calculate the atom economy of its synthesis.
新大纲明确列出了必要的数学能力：有效数字的使用、比例推理、公式变形、解释图像斜率以及计算百分产率。一道典型题目可能要求学生根据百分组成数据确定化合物的经验式，然后计算其合成反应的原子经济性。
To succeed, learners should practice applying these skills in chemical contexts. The days of treating chemistry numbers as simple plug-and-chug are over. The 2026 exams expect students to show clear working, use correct units, and check the plausibility of their answers.
为了成功，学习者应练习在化学情境中应用这些技能。把化学计算当作简单代入公式的时代已经结束。2026年的考试期望学生展示清晰的解题步骤、使用正确的单位并检查答案的合理性。
5. Key Topic Adjustments | 核心主题调整
Several topic areas have been refined to improve coherence and reduce overlap. The Periodic Table section now places earlier emphasis on trends in Group 1, Group 7, and the transition elements, with a stronger narrative linking electronic structure to reactivity.
多个主题领域经过精炼，以提高连贯性并减少重叠。周期表部分现在更早地强调第1族、第7族和过渡元素的趋势，并用更强的内容脉络将电子结构与反应活性联系起来。
Organic chemistry has been expanded to include a broader introduction to polymers. Both addition and condensation polymerisation are now core content for the Extended tier, and students must be able to draw repeat units and identify monomers from given polymer structures. Environmental issues related to plastics, such as recycling codes and incineration, are also included.
有机化学部分得到扩展，引入了更广泛的聚合物介绍。加成聚合和缩聚反应现在都是拓展层级的核心内容，学生必须能够画出重复单元并根据给定的聚合物结构识别单体。与塑料相关的环境问题，如回收标识和焚烧，也被纳入其中。
Electrochemistry has been restructured to emphasise the applications of electrolysis. While the principles remain the same, the syllabus now explicitly expects students to explain the extraction of aluminium, electroplating, and the purification of copper, using half-equations and electron flow arguments.
电化学部分经过重新组织，强调电解的应用。虽然原理保持不变，但大纲现在明确要求学生使用半反应式和电子流动论证来解释铝的提取、电镀和铜的精炼。
6. Introduction of New Content | 新增内容
The 2026 syllabus introduces several new topics that reflect the frontiers of modern chemistry. One notable addition is green chemistry and sustainability. Students will learn about the 12 principles of green chemistry, carbon footprints, and the development of biodegradable polymers. This content is directly assessed in both Paper 2 (Multiple Choice) and Paper 4.
2026年教学大纲引入了几项新主题，反映了现代化学的前沿。一个显著的补充是绿色化学与可持续性。学生将学习绿色化学的12条原则、碳足迹以及可生物降解聚合物的开发。这部分内容在Paper 2（选择题）和Paper 4中都会被直接考查。
Another fresh topic is atomic structure – specifically, an introduction to isotopes and their uses in medicine and industry. While basic atomic structure was previously covered, the updated syllabus expects students to relate isotopic abundance to relative atomic mass calculations and describe applications such as cobalt-60 in radiotherapy and iodine-131 in thyroid imaging.
另一项新增内容是原子结构——具体而言，引入了同位素及其在医学和工业中的应用。虽然基础的原子结构之前已有涉及，但更新后的大纲要求学生将同位素丰度与相对原子质量计算联系起来，并描述钴-60在放射治疗和碘-131在甲状腺成像中的应用。
A brief section on nanomaterials has been added under the topic of bonding and structure. Learners should know what fullerenes and carbon nanotubes are, how their structures relate to properties, and potential uses in electronics, drug delivery, and as lubricants. This addition reflects the evolving landscape of materials science.
在键合与结构主题下新增了纳米材料的简短章节。学习者应了解富勒烯和碳纳米管是什么，其结构如何与性质相关，以及它们在电子、药物输送和润滑剂中的潜在用途。这一补充反映了材料科学不断发展的面貌。
7. Deletion of Outdated Material | 删除过时内容
To make room for new, relevant content, some legacy topics have been removed or significantly reduced. The extraction of iron in the blast furnace, a staple of older syllabi, is no longer required. Instead, focus has shifted to more sustainable metal extraction methods, such as phytomining and bioleaching, which are introduced within the reactivity series topic.
为了给新的相关内容腾出空间，一些旧有主题已被删除或大幅缩减。旧大纲中的经典内容“高炉炼铁”已不再要求。焦点转向了更可持续的金属提取方法，例如植物采矿和生物浸出，这些在金属活动性顺序主题中予以介绍。
Detailed recall of the Haber process conditions as isolated facts has been replaced by a broader understanding of reversible reactions and equilibrium. Students still need to know the Haber process as an industrial example, but the emphasis is on applying Le Chatelier’s principle to explain yield optimisation, rather than memorising a temperature of 450 °C and a pressure of 200 atm without context.
对哈伯法工艺条件作为孤立事实的详细记忆已被对可逆反应和平衡的更广泛理解所取代。学生仍需要了解哈伯法作为一个工业实例，但重点在于应用勒夏特列原理解释产率优化，而非脱离背景地记忆450°C和200个大气压。
The section on hardness of water, which formerly occupied a whole chapter, has been condensed into a single point within the context of chemical analysis and ion testing. Similarly, detailed study of specific food additives has been removed, and only a general awareness of additives as examples of esters or acidulants remains.
过去占据一整章的“水的硬度”部分已被浓缩为化学分析和离子检验背景下的一个要点。同样，对特定食品添加剂的详细研究已被删除，只保留了对添加剂作为酯或酸度调节剂实例的一般认识。
8. Updated Question Formats | 题目格式更新
The structure of exam papers has been fine-tuned to improve validity and accessibility. Paper 1 and Paper 2 (Multiple Choice) now include more data-response items where a diagram, table, or graph is presented alongside the question stem. This discourages guesswork and rewards careful reading.
试卷结构经过微调，以提高效度和可及性。Paper 1和Paper 2（选择题）现在包含更多数据响应题，题目会附带图表或表格。这减少了猜测成分，奖励仔细阅读的能力。
In Paper 4 (Theory Extended), there is a notable increase in ‘explain and predict’ style questions. For instance, rather than simply stating that sodium reacts vigorously with water, students might be given the reaction of rubidium with water and asked to predict and explain the outcome for francium, drawing on periodic trends.
在Paper 4（理论拓展）中，“解释与预测”类题型显著增加。例如，不再是简单地陈述钠与水反应剧烈，而是可能给出铷与水的反应，要求学生根据周期表趋势预测并解释钫的反应结果。
Structured questions now often bundle together objectives from different sections of the syllabus. A single question might start with a dot-and-cross diagram for an ionic compound, then ask for a calculation of molar mass, and finally inquire about the environmental impact of its disposal. This integrated approach demands mental flexibility and holistic knowledge.
简答题现在经常将来自大纲不同部分的目标捆绑在一起。一道题目可能以离子化合物的点叉图开始，然后要求计算摩尔质量，最后询问其处置的环境影响。这种综合性的考查方式要求思维灵活性和整体性知识。
9. Study Strategies for 2026 | 针对2026的学习策略
Adapting to the 2026 exam requires a proactive shift in study habits. Rote learning of textbook paragraphs is no longer sufficient. Instead, students should adopt active recall techniques combined with extensive practice of past-paper-style questions under timed conditions.
适应2026年考试需要主动改变学习习惯。死记硬背教科书段落已不足以应对。学生应采用主动回忆技术，并结合在限时条件下广泛练习真题风格的题目。
Creating concept maps that link different topics is an excellent preparation strategy. For example, connecting the electrolysis of brine with the production of chlorine for water treatment, and then linking that to the environmental discussion of halogenated compounds, will mirror the integrated nature of the new exam.
绘制连接不同主题的概念图是一种极好的备考策略。例如，将盐水电解与用于水处理的氯气生产联系起来，然后再与卤代化合物的环境讨论相关联，这将反映新考试的综合性质。
Hands-on laboratory practice cannot be overstated. If formal lab access is limited, students should use high-quality simulations and video demonstrations to visualise practical procedures. They must be able to describe not just what happens, but why each step is necessary and how errors could be minimised.
动手实验操作的重要性再怎么强调也不为过。如果正式的实验室条件有限，学生应使用高质量的模拟和视频演示来视觉化实验程序。他们必须不仅能描述发生了什么，还要能解释每一步为何必要，以及如何将误差降至最小。
10. Resources and Support | 资源与支持
Cambridge International provides a suite of updated resources to support the 2026 syllabus. The official learner guide, scheme of work, and specimen papers are essential starting points. These documents reveal the exact wording of command words and the expected depth of answers for each topic.
剑桥国际提供了一套更新资源以支持2026年教学大纲。官方的学习者指南、教学计划和样卷是不可或缺的起点。这些文件揭示了指令词的确切措辞以及每个主题答案的预期深度。

When selecting revision guides, ensure they are explicitly labelled for the 2026 examination. Using outdated 2023–2025 materials risks covering removed content and missing the new green chemistry and nanomaterials topics. Cross-reference with the latest syllabus checklist to stay on track.
在选择复习指南时，务必选择明确标注适用于2026年考试的版本。使用过时的2023–2025资料可能会涉及已删除内容，并遗漏新的绿色化学和纳米材料主题。对照最新的大纲清单以确保不偏离轨道。
11. Trends in Mark Schemes and Grading | 评分方案与等级划分趋势
Mark schemes for 2026 onwards will place a higher premium on precise scientific language and the correct use of units. Vague terminology such as ‘it gets hot’ will not earn a mark where ‘exothermic reaction releases heat energy to the surroundings’ is expected. Precision in chemical terminology is now a clear discriminator between grades.
2026年起的评分方案将更加青睐精确的科学语言和正确使用单位。在期望“放热反应向周围释放热能”的地方，诸如“它变热了”之类的模糊术语将无法获得分数。化学术语的精确性现在成为区分等级的明显因素。
Grade thresholds are anticipated to remain stable, but the distribution of marks across papers means that slightly more emphasis is placed on the theory papers than on the practical alternative. However, because practical skills are also assessed in the theory papers, consistent performance across all components is critical.
预计等级分数线将保持稳定，但各卷分数的分布意味着理论卷的权重略高于实验替代卷。然而，由于实验技能也在理论卷中被评估，所有部分的一贯表现至关重要。
The trend toward awarding marks for showing working in calculations will continue. Even if the final answer is incorrect, a well-structured method using the correct formula and units can still earn significant credit. This encourages students to develop transparent, logical problem-solving strategies.
在计算中展示解题步骤可获得分数的趋势将继续下去。即使最终答案错误，使用正确公式和单位的、结构良好的方法仍能获得可观的分数。这鼓励学生发展透明、逻辑清晰的问题解决策略。
12. Frequently Asked Questions | 常见问题
