This article explores what is new, what is being emphasised, and how to prepare effectively for the 2026 exams.
当 Year 11 的学生望向 2026 年的 CAIE IGCSE 进阶数学（0606）考试时，理解新考纲（2025–2027）带来的深远影响变得至关重要。这份修订后的课程于 2025 年首次开考，它在内容、评估目标和出题风格上的显著变化将持续塑造 2026 年的试卷。对于志在夺取高分的同学而言，及早了解这些变化以及 2025 年首考中浮现的趋势，将构成关键的优势。本文将探索哪些内容发生了改变，哪些知识点正被重点强调，以及如何为 2026 年的考试进行有效备考。
1. The New 2025–2027 Syllabus at a Glance | 2025–2027 版考纲速览
The CAIE IGCSE Additional Mathematics syllabus was updated for first teaching in 2023 and first examination in 2025. The 2026 series will be the second opportunity for students to sit this revised qualification. The update is not a minor tweak; it restructures topic emphasis and raises expectations in analytical thinking. Teachers and students must shift their preparation from relying on past papers from the pre-2025 era, as many question types and content boundaries have moved.
CAIE IGCSE 进阶数学考纲于 2023 年首次教学、2025 年首次考试时进行了更新。2026 年的考试将是学生参加这一修订后资格的第二次机会。这次更新并非小修小补，它重构了主题的侧重点，并拔高了对分析性思维的期望。师生必须将备考重心从依赖 2025 年之前的旧题中转移出来，因为许多题型和内容边界已经发生了变化。
2. Key Content Additions: Functions and Graphs | 关键内容新增：函数与图像
One of the most visible changes is the strengthened treatment of functions. Students are now required to sketch and interpret piecewise functions, absolute value functions of the form f(x) = |ax + b|, and transformations including f(x) + k, f(x + k), kf(x), f(kx), |f(x)|, and f(|x|). Unlike the previous syllabus, where these were treated implicitly, the new curriculum demands explicit graphical manipulation and equation solving with all these forms. Expect questions in 2026 to combine multiple transformations in a single problem.
最显著的变化之一是对函数的强化处理。如今要求学生能够描绘并解释分段函数、形如 f(x) = |ax + b| 的绝对值函数，以及包括 f(x) + k、f(x + k)、kf(x)、f(kx)、|f(x)| 和 f(|x|) 在内的变换。与旧考纲中这些内容被隐性处理不同，新课程明确要求进行显式的图像操作以及运用这些形式求解方程。可以预见，2026 年的考题很可能会在一道题目中综合多个变换。
3. Adjusted Topics in Algebra and Equations | 代数与方程篇章的调整
Solving equations involving absolute values, such as |2x – 3| = x + 1, now carries greater weight and can appear in both non-calculator papers. Quadratic and cubic inequalities, long a staple, are now assessed more often through unfamiliar contexts and word problems. The syllabus encourages linking algebraic manipulation to geometric interpretation on coordinate axes, so expect to see inequalities shaded on graphs and linked to discriminant analysis.
涉及绝对值的方程求解，比如 |2x – 3| = x + 1，现已被赋予更高的权重，并可能同时出现在两份不可使用计算器的试卷中。二次与三次不等式虽然是老面孔，但现在更常通过陌生情境和应用题来评估。考纲鼓励将代数操作与坐标轴上的几何解释联系起来，因此可以预期试卷中会出现需要绘制图像中的阴影区域并结合判别式分析的不等式题目。
4. Sequences and Series: Deeper Proof Elements | 数列与级数：更深入的证明元素
The arithmetic and geometric sequence topics remain, but there is a renewed emphasis on deriving formulae and on the sum to infinity of a convergent geometric series. Questions may ask candidates to prove the formula for the sum of the first n terms, or to apply summation notation (Σ) to complex sequences. For 2026, students should be ready to handle series problems that require them to deduce common difference or ratio from partial sums, rather than simply plugging numbers.
等差与等比数列的课题虽然保留，但如今更加强调公式的推导以及收敛型等比数列的无穷和。考题可能会要求考生证明前 n 项和的公式，或者将求和符号（Σ）应用于复杂的数列。对于 2026 年的备考，学生应当做好准备去处理那些需要从部分和倒推公差或公比的级数问题，而非仅仅进行数值代入。
5. Significant Shift in Assessment Objectives | 评估目标的重大转变
The weighting of assessment objectives has been remodelled. AO1 (Knowledge and Understanding) accounts for 40% of the marks, AO2 (Application and Interpretation) for 30%, and AO3 (Analysis and Evaluation) has risen to 30%, up from 25% in the previous syllabus. This deliberate increase in AO3 signifies that more questions will demand multi-step reasoning, justification, and evaluation of solutions. The 2026 papers will continue to test whether students can think beyond routine procedures.
评估目标的权重已被重新设计。AO1（知识与理解）占 40%，AO2（应用与解释）占 30%，而 AO3（分析与评估）则从旧考纲的 25% 上升至 30%。这一有意为之的 AO3 权重增加，意味着会有更多的题目要求多步推理、论证以及对解法的评估。2026 年的试卷将继续检验学生能否进行超越常规步骤的思考。
6. Exam Paper Format and Restrictions | 试卷结构与限制
There are still two papers, Paper 1 and Paper 2, each lasting 2 hours and worth 80 marks. Both papers remain entirely non-calculator. The question counts may fluctuate slightly to accommodate the increased AO3 items, but the total mark allocation stays constant. In 2026, students can expect a similar structure to 2025: around 10–12 questions per paper, with the final questions typically integrating multiple topics and requiring the highest level of analysis.
考试依然由两份试卷组成，Paper 1 与 Paper 2 各持续 2 小时，满分 80 分。两份试卷依旧全程禁用计算器。题目数量可能会为适应新增的 AO3 权重而出现微小波动，但总分分配保持不变。2026 年的学生可以预期与 2025 年类似的结构：每份试卷约含 10 至 12 道题，且最后几道题通常会综合多个主题，并要求最高层次的分析能力。
7. Emerging Trends from the 2025 First Examination | 2025 首考中浮现的趋势
Feedback from the 2025 series highlights a few clear trends that will carry into 2026. Modelling and real-world context questions appeared more frequently, linking calculus and coordinate geometry to optimisation problems. Transformation of functions was no longer a small standalone question but was embedded into larger problems requiring sketching, domain/range analysis, and equation solving simultaneously. The demand for clear, logical working has intensified, as partial marks rely heavily on showing valid reasoning.
来自 2025 年考试系列的反馈突显了几个将延续至 2026 年的清晰趋势。建模与真实世界背景的题目出现得更加频繁，将微积分和坐标几何与最优化问题联系起来。函数的变换不再是一个孤立的小题，而是嵌入到需要同时进行草图绘制、定义域/值域分析以及方程求解的大题中。试卷对清晰、逻辑严密的解题步骤的要求进一步增强，因为过程分在很大程度上依赖于展示有效的推理。
8. Deeper Integration of Coordinate Geometry and Calculus | 坐标几何与微积分的深度交融
A notable trend is the tight integration of coordinate geometry with differentiation and integration. In 2026, students should expect to see problems where they must find equations of tangents and normals, then use them to calculate areas of triangles or distances, incorporating perpendicularity and midpoints. Second derivative tests for maxima and minima are firmly embedded in optimisation questions, often with a preliminary modelling step that requires setting up the function from a geometric or physical situation.
一个值得关注的新趋势是坐标几何与微分、积分的紧密交融。在 2026 年，学生应当预期会遇到这样的题目：他们要找出切线和法线的方程，然后利用它们去计算三角形的面积或距离，且题目中会融入垂直关系和线段中点。用于判断极大、极小值的二阶导数检验被牢牢嵌入最优化问题之中，且往往需要一个前置的建模步骤，要求从几何或物理情境中建立目标函数。
9. Emphasis on Trigonometry and Exact Values | 三角学与精确值的强调
Trigonometry now demands not only proficiency in solving equations over specified intervals but also a fluent use of exact trigonometric values (e.g., sin 30° = 1/2, tan 60° = √3) in calculus and geometry problems. Radian measure continues to be required for arc length and sector area, but the syllabus encourages more connections with coordinate geometry and integration, such as finding area under a sine curve. In 2026, compound angle identities may appear in more complex multi-step simplification tasks.
如今三角学不仅要求学生熟练掌握在规定区间内解方程，还要求在微积分和几何问题中能流畅地运用精确三角函数值（例如 sin 30° = 1/2，tan 60° = √3）。弧度制依然是计算弧长和扇形面积时的必备知识，但新考纲鼓励将三角学与坐标几何、积分更多地联系起来，比如求解正弦曲线下的面积。2026 年的考试中，复合角恒等式很可能会出现在更复杂的多步化简任务里。
10. Strategic Preparation for Year 11 Students in 2026 | 给 2026 年 Year 11 学生的备考策略
Success in 2026 hinges on shifting study habits from memorisation to deep understanding. Students should practise sketching and transforming all types of functions, including piecewise and absolute value graphs, until the process becomes intuitive. Working through open-ended problems that require deriving formulas or proving statements will build AO3 skills. Because both papers are non-calculator, mental arithmetic and exact value fluency need to be maintained through daily drills. Using the 2025 papers and specimen materials is essential, but students must also revisit challenging pre-2025 questions that align with the new emphasis on analysis.
要在 2026 年取得成功，关键在于将学习习惯从死记硬背转变为深度理解。学生应反复练习各种类型函数的草图和变换，包括分段函数和绝对值图像，直到这一过程化为直觉。多做那种需要推导公式或证明结论的开放性问题，能有效培养 AO3 技能。鉴于两份试卷都禁用计算器，需要通过日常训练来保持心算能力和精确值运用的娴熟度。使用 2025 年的真题和样卷至关重要，但学生也应重温那些符合新分析重点的、具有挑战性的 2025 年前旧题。
11. The Role of Algebraic Fluency Under Time Pressure | 时间压力下代数流利度的角色
The increased AO3 content means that some questions will require considerable unpacking before the core algebra begins. Students who can manipulate surds, indices, logarithms, and trigonometric identities swiftly will recover precious time for the higher-order thinking parts of each question. In 2026, expect the papers to feel slightly more time-pressured if your algebraic fundamentals are not automatic. Regular timed practice focusing on correct, rapid simplification is as important as learning new content.
AO3 内容的增加意味着，某些题目在进入核心代数之前需要进行大量的解构。那些能够迅速处理根式、指数、对数和三角恒等式的学生，将会为解答每道题中的高阶思维部分赢回宝贵的时间。在 2026 年，若你的代数基本功尚未达到自动化，你很可能会感觉试卷时间略显紧迫。定期进行以正确、快速化简为目标的时间限制练习，其重要性丝毫不亚于学习新知识。
12. Looking Ahead: A More Mathematical Mindset | 展望未来：更数学化的思维模式
Ultimately, the 2026 CAIE IGCSE Additional Mathematics exam rewards students who approach the subject as a connected web of ideas, not a checklist of isolated techniques. The syllabus changes and the trends from 2025 confirm that the examiners seek evidence of reasoning, precise communication, and the ability to apply mathematics in unfamiliar scenarios. With structured revision that targets these competencies, Year 11 students can approach the 2026 exams with confidence and a clear strategic edge.
归根结底，2026 年的 CAIE IGCSE 进阶数学考试青睐的是那些将该学科视作一张相互关联的思想之网、而非一份孤立技巧清单的学生。考纲的变化与 2025 年的趋势都确认，考官所寻找的是推理过程、精确的数学表达以及在陌生场景中应用数学的能力。只要通过结构化的复习来瞄准这些核心素养，Year 11 的学生们便能带着自信与清晰的策略优势去迎战 2026 年的考试。
