2. Revised Assessment Objectives and Their Weighting | 修订后的评估目的及其权重
Assessment Objective 1 (AO1: Knowledge with understanding) now accounts for approximately 40% of the total marks, down from a higher proportion in the previous syllabus. Conversely, AO2 (Handling information and problem-solving) and AO3 (Experimental skills and investigations) have increased in weighting, collectively making up the remaining 60%. This shift signals a clear move away from rote learning towards reasoning and practical application.
评估目的一(AO1：知识与理解)现在约占总分的40%，低于之前大纲中的比例。相反，AO2（信息处理与问题解决）和AO3（实验技能与探究）的权重增加，共占剩余的60%。这一变化明确表明从死记硬背向推理论证和实际应用的方向转变。
3. Content Reorganization: Core vs Extended | 内容重组：核心内容与拓展内容
The syllabus has been reorganised from 14 topics into 12 broad themes, providing a more coherent progression of ideas. The 'Core' curriculum now lays a stronger conceptual foundation, while the 'Extended' supplement deepens understanding with more quantitative treatments and real-world contexts. Some crossover topics have been merged to avoid repetition, and the distinction between Core and Extended is more clearly reflected in the question papers.
大纲已从14个主题重组为12个更广泛的主题，使知识脉络更为连贯。“核心”课程现在打下更坚实的概念基础，而“拓展”补充内容通过更多定量的方法和实际情境加深理解。部分交叉主题被合并以避免重复，核心与拓展之间的区别在试卷中也得到了更清晰的体现。
4. New Topics Emphasising Sustainability and Green Chemistry | 新增主题：强调可持续性与绿色化学
A defining feature of the new syllabus is the integration of sustainability principles. Students will now encounter life cycle assessments (LCA) for materials, the principles of green chemistry, and the chemistry of the circular economy. Nanotechnology and its medical applications, as well as carbon capture and storage, are introduced to highlight cutting-edge developments.
新大纲的一个显著特征是对可持续性原则的融入。学生现在将学习材料的生命周期评价(LCA)、绿色化学原则以及循环经济的化学原理。同时引入了纳米技术及其医学应用，以及碳捕集与封存，以突出前沿发展。
The chemistry of bioplastics and biodegradable polymers has been added to the organic chemistry section, while traditional pollution topics have been reframed to emphasise prevention and sustainable alternatives rather than just consequences.
有机化学部分新增了生物塑料和可生物降解聚合物的化学知识，而传统的污染话题则被重新构建，以强调预防和可持续替代方案，而非仅仅关注后果。
5. Topics Removed or Significantly Reduced | 删除或大幅精简的主题
Several topics have been removed to make space for contemporary content and to reduce the assessment burden. The table below summarises the most notable deletions and reductions:
为了给现代内容腾出空间并减轻评估负担，一些主题已被删除。下表总结了最值得注意的删除和缩减内容：
| Removed or Reduced Topics | Details |
|---|---|
| Hardness of water and treatment | No longer required in Core or Extended |
| Detailed fuel cell construction | Only the principles and advantages are retained |
| Manufacture of ammonia (Haber process conditions) | Reduced to core principles; no detailed pressure/temperature trade-offs |
| Some specific organic reaction pathways | e.g., formation of esters from acyl chlorides removed from Extended |
These cuts allow deeper exploration of the remaining topics and reduce the pressure of memorising isolated facts.
这些删减使得剩余主题能够得到更深入的探讨，并减轻了记忆孤立知识点的压力。
6. Changes in Examination Papers and Duration | 试卷结构与考试时长变化
The number of papers and the overall duration remain familiar, but there are subtle shifts. Paper 1 (Multiple Choice) stays at 40 questions in 45 minutes, yet the proportion of application-based questions has risen. Paper 2 (Core) and Paper 3 (Extended) are both 1 hour 15 minutes; Paper 3 now includes at least one 'unstructured' extended response question that requires students to synthesise information across topics. Paper 4 (Alternative to Practical) continues to be 1 hour, with an increased focus on experimental design and data evaluation.
试卷数量和总体时长保持不变，但有细微变化。Paper 1（选择题）仍为40题45分钟，但应用型题目的比例有所上升。Paper 2（核心）和Paper 3（拓展）时长均为1小时15分钟；Paper 3现在至少包含一道“开放式”拓展回答题，要求学生综合跨主题的信息。Paper 4（实验替代测试）仍为1小时，但更加注重实验设计和数据评价。
| Paper | Duration | Key Change |
|---|---|---|
| Paper 1 MC | 45 min | More analysis of graphs, diagrams and data tables |
| Paper 2 Core | 1 h 15 min | Fewer pure recall questions; more context-based scenarios |
| Paper 3 Extended | 1 h 15 min | Synthetic extended-response question worth 6-8 marks |
| Paper 4 Alt. to Practical | 1 h | Planning investigations and evaluating methods receive more marks |
Understanding these structural adjustments helps in targeted revision and time management during the exam.
理解这些结构调整有助于在复习和考试过程中进行有针对性的时间管理。
7. Practical Assessment: New Emphasis on Planning and Evaluation | 实验评估：对计划与评价的新强调
While the format of the practical papers (Paper 5 or Paper 6) remains similar, the marking criteria have been refined to reward higher-level investigative skills. Students are expected not only to describe experimental procedures but to justify choices of apparatus, identify sources of error, and propose realistic improvements. Questions on evaluating the reliability of data and suggesting further investigations have become standard.
虽然实验试卷（Paper 5或Paper 6）的格式变化不大，但评分标准已经过细化，以奖励高层次的探究技能。学生不仅要描述实验步骤，还需说明装置选择的理由、识别误差来源并提出切实可行的改进方案。关于数据可靠性评价及建议进一步探究的题目已成为常态。
For the alternative to practical paper, there is a clear shift from testing familiarity with standard lab techniques to assessing the ability to design a fair test from a given hypothesis.
对于实验替代试卷，已明显从测试标准实验技术的熟悉度转向评估根据给定假设设计公平实验的能力。
8. Increased Weighting of Mathematical Skills | 数学技能权重的增加
Approximately 25% of the total marks now directly involve mathematical skills, up from around 20% in the previous specification. This includes mole calculations, percentage yield, atom economy, titration results, and gas volume calculations. A strong grasp of ratios, proportions and graph interpretation is essential.
现在约25%的总分直接涉及数学技能，高于之前大纲中约20%的比例。这包括摩尔计算、产率百分比、原子经济性、滴定结果以及气体体积计算。扎实掌握比和比例、图表解读是至关重要的。
n = m / M
concentration = amount of solute / volume of solution
Students must be comfortable rearranging these equations and substituting values with correct units. Practice with standard form and significant figures is equally important, as mark schemes have become stricter on precision.
学生必须能够熟练变换这些方程并代入正确的单位。标准形式和有效数字的练习同样重要，因为评分方案在精度上已变得更为严格。
9. Shifts in Command Words and Question Styles | 指令词与问题形式的变化
Command words such as 'evaluate', 'justify', 'predict' and 'suggest' appear more frequently, replacing many of the 'state' and 'define' questions that dominated older papers. This demands that students can weigh up evidence, provide reasoned arguments, and apply chemical principles to unfamiliar situations. The new syllabus encourages teachers to use case studies and real-world scenarios during lessons.
诸如“评价”、“论证”、“预测”和“建议”等指令词出现得更加频繁，取代了旧试卷中大量使用的“陈述”和“定义”类题目。这要求学生能够权衡证据、给出有理有据的论证，并将化学原理应用于陌生情境。新大纲鼓励教师在课堂上使用案例研究和真实情境。
One example is a question presenting data on different materials for packaging, asking students to evaluate which is most sustainable based on LCA data and chemical properties – a task requiring synthesis of knowledge from several areas.
例如，一道题目可能会提供不同包装材料的数据，要求学生基于生命周期评价数据和化学性质评价哪种材料最具可持续性——这是一项需要综合多个领域知识的任务。
10. Impact on Paper 1 Multiple Choice | 对Paper 1选择题的影响
The multiple-choice paper is no longer a test of rapid recall alone. A growing number of items involve interpreting tables, graphs or experimental setups, and then selecting the correct conclusion. Distractors are carefully designed to catch misconceptions, meaning that superficial learning will be heavily penalised. Candidates should expect to see more 'best fit' questions where multiple options are partly correct, but one is the most scientifically justified.
选择题试卷不再仅仅是快速回忆的测试。越来越多的题目涉及解读表格、图表或实验装置，然后选择正确的结论。干扰项经过精心设计以捕捉错误概念，这意味着浅层学习将受到严重惩罚。考生应预期看到更多“最佳匹配”题，其中多个选项部分正确，但只有一项在科学上最为合理。
11. Preparation Strategies for the 2026 Exams | 2026年考试备考策略
To succeed under the new syllabus, students should prioritise the following strategies:
- Build robust conceptual maps linking topics rather than memorising isolated facts.
- Regularly practise application questions, especially those requiring explanations in unfamiliar contexts.
- Master the mathematical formulae early and apply them in weekly calculation practice.
- Engage with sustainability and green chemistry resources to become comfortable with the new vocabulary and LCA interpretation.
- Work through past papers from the 2023–2025 syllabus but supplement with new-style questions provided by Cambridge specimen papers for 2026.
要在新大纲下取得成功，学生应优先采取以下策略：
- 构建连接各主题的强健概念图，而非死记硬背孤立知识点。
- 定期练习应用类题目，尤其是那些需要在陌生情境下进行解释的题目。
- 尽早掌握数学公式，并通过每周计算练习加以应用。
- 主动学习可持续性和绿色化学资源，熟悉新的词汇和生命周期评价解读。
- 练习2023–2025年大纲的历年真题，同时补充剑桥提供的2026年样卷中的新题型。
Formative assessment and active revision techniques, such as self-quizzing and teaching the material to a peer, are particularly effective for cementing the higher-order thinking required.
形成性评估和主动复习技巧，如自我测试和向同伴讲解材料，对于巩固所需的高阶思维特别有效。
12. Embracing the Trends: A Forward-Looking Approach | 顺应趋势：前瞻性的方法
The 2026 syllabus changes are not obstacles but opportunities to study chemistry in a more engaging and relevant way. By shifting the focus towards analysis, sustainability and practical reasoning, Cambridge has aligned the qualification with the skills demanded by A-Level and university science courses. Students who adapt their learning habits early will not only excel in the IGCSE but also build a superior foundation for future scientific endeavours.
2026年的大纲变化不是障碍，而是以更具吸引力和关联性的方式学习化学的契机。将重心转向分析、可持续性和实践推理，剑桥使这一资格证书与A-Level和大学科学课程所需的技能保持一致。及早调整学习习惯的学生不仅能在IGCSE中出类拔萃，还能为未来的科学探索打下更坚实的基础。
