1. Introduction to the 2026 Syllabus Update | 2026年教学大纲更新简介
The Cambridge IGCSE Engineering syllabus (code 0975) has been revised for first teaching in 2024 and first examination in 2026. This update aligns the course with Industry 4.0, integrating smart manufacturing, digital twins, and the Internet of Things (IoT). Teachers will notice a stronger fusion of mechanical, electrical, and software principles across all modules.
剑桥 IGCSE 工程教学大纲（代码 0975）已经修订，于2024年首次教学，2026年首次考试。此次更新使课程与工业4.0保持一致，融合了智能制造、数字孪生和物联网（IoT）。教师会注意到所有模块中机械、电气和软件原理的更深度融合。
A central driver for the revision is the global commitment to net-zero targets. Topics such as life cycle assessment (LCA), renewable energy systems, and sustainable materials have been expanded. Students must now critically appraise the environmental consequences of engineering choices.
修订的核心驱动力是全球对净零目标的承诺。生命周期评估（LCA）、可再生能源系统和可持续材料等主题得到了拓展。学生现在必须批判性地评估工程选择的环境后果。
2. New Assessment Objectives | 新的评估目标
The assessment objectives (AOs) have been rebalanced to emphasise higher-order skills. The three AOs are: AO1 – Knowledge with understanding, AO2 – Application of knowledge and analysis, and AO3 – Evaluation and design. AO3 now commands a significantly higher weighting, requiring students to iterate designs and provide reasoned justifications.
评估目标（AO）已经重新权衡，以强调高阶技能。三个AO分别为：AO1 – 知识理解，AO2 – 知识应用与分析，以及 AO3 – 评估与设计。AO3 现在占有更高的权重，要求学生迭代设计并提供合理的论证。
Previously, factual recall dominated the marks. In the 2026 exams, about 40% of the total marks will be assigned to AO3, compared with 30% in earlier specifications. Consequently, memorising formulas is insufficient; learners must practise open-ended design problems and defend material choices quantitatively.
以前，事实记忆占据了分数的绝大部分。在2026年的考试中，约40%的总分数将分配给AO3，而早期大纲中仅为30%。因此，仅记忆公式是不够的；学习者必须练习开放式的设计问题，并量化地辩护材料选择。
| Assessment Objective | Pre-2026 Weighting | 2026 Weighting |
|---|---|---|
| AO1 Knowledge with understanding | 40% | 30% |
| AO2 Application and analysis | 30% | 30% |
| AO3 Evaluation and design | 30% | 40% |
3. Shift Towards Sustainable Engineering | 转向可持续工程
Sustainability is now woven throughout the syllabus, not just a standalone chapter. Questions will ask learners to compute carbon footprints, compare the life cycles of materials, and propose cradle-to-cradle solutions. For example, a Paper 2 scenario might involve selecting between aluminum and a bio-composite for a bicycle frame, considering end-of-life recyclability.
可持续性现在贯穿整个教学大纲，而不再是单独的一章。题目会要求学习者计算碳足迹、比较材料的生命周期，并提出从摇篮到摇篮的解决方案。例如，试卷二中的一个情境可能涉及在铝和生物复合材料之间为自行车车架选材，并考虑报废后可回收性。
Coursework will now require a sustainability log where students document every eco-friendly decision. This includes evidence of minimising offcuts, the energy rating of machinery used, and a waste management plan. Marks are awarded for realistic and justified environmental considerations.
课程作业现在要求提供可持续性日志，学生需记录每一个环保决策。这包括最小化边角料的证据、所用机械的能源评级以及废物管理计划。评分会奖励切合实际且有合理依据的环保考量。
4. Integration of Digital Design Tools | 数字设计工具的整合
Proficiency in Computer-Aided Design (CAD) and Computer-Aided Manufacturing (CAM) is now mandatory. Candidates must be able to create accurate 3D parametric models and understand additive manufacturing processes. The syllabus expects students to generate G-code from their CAD models and explain how a CNC machine interprets it.
精通计算机辅助设计（CAD）和计算机辅助制造（CAM）现已成为强制性要求。考生必须能够创建精确的三维参数化模型，并理解增材制造过程。大纲要求学生能够从自己的 CAD 模型生成 G 代码，并解释 CNC 机器如何解读它。
Basic principles of Finite Element Analysis (FEA) are also introduced. Although running full simulations is not required, students must interpret stress distribution plots and identify regions of high stress concentration. The concept of factor of safety is tested through simple calculations:
还引入了有限元分析（FEA）的基本原理。虽然不要求运行完整的模拟，但学生必须解释应力分布图并识别高应力集中区域。安全系数的概念通过简单的计算进行测试：
Direct Stress: σ = F / A
In the exam, a diagram of a loaded bracket might be shown, and candidates must suggest geometric modifications to reduce stress peaks.
在考试中，可能会展示一个受载支架的示意图，考生必须建议几何修改以降低应力峰值。
5. Changes in Non-Exam Assessment (NEA) | 非考试评估的变化
The Non-Exam Assessment (Component 2) has been reweighted from 50% to 40% of the final grade. This rebalancing aims to give more prominence to the two written papers. The NEA project brief is now set by Cambridge, with three thematic options released each year.
非考试评估（组成部分二）的权重已从50%调整为40%。这一重新平衡旨在突出两个笔试的份量。NEA 的项目任务现在由剑桥命题，每年发布三个主题选项。
The portfolio requirements have been streamlined but demand deeper reflection. Students must include a digital log that tracks collaboration (where permitted), a detailed manufacturing plan with justification of processes, and a final prototype. Evaluation must reference testing data against the product specification.
作品集要求已经简化，但要求更深入的反思。学生必须包含一个跟踪协作（如果允许）的数字日志、一份带有工艺理由的详细制造计划，以及最终原型。评估必须引用对照产品规格的测试数据。
6. Exam Paper Structure Adjustments | 试卷结构调整
From 2026, Paper 1 (Theory) is a 2‑hour paper worth 30% of the total marks. It contains multiple‑choice, short‑answer, and structured questions drawn from all syllabus sections. Paper 2 (Problem‑Solving) runs for 1.5 hours, also worth 30%, and focuses on applying knowledge to unfamiliar scenarios.
从2026年起，试卷一（理论）为2小时，占总分的30%。它包含来自所有大纲部分的选择题、简答题和结构化问题。试卷二（问题解决）为1.5小时，也占总分的30%，专注于将知识应用于不熟悉的情境。
Paper 2 introduces a dedicated section where learners analyse a detailed engineering context and propose a feasible solution. Responses must include annotated sketches, necessary calculations, and a discussion of alternatives. A formula sheet will be provided, but candidates must recall fundamental relationships such as Ohm’s Law and Young’s Modulus:
试卷二引入了一个专门的部分，学习者需要分析详细的工程背景并提出可行的解决方案。答案必须包含带注释的草图、必要的计算，以及对替代方案的讨论。考试会提供公式表，但考生必须记住欧姆定律和杨氏模量等基本关系：
Ohm’s Law: V = I × R
Young’s Modulus: E = σ / ε
7. Emphasis on Real-World Problem Solving | 强调实际问题解决
The 2026 syllabus embeds authentic case studies from sectors like aerospace, renewable energy, and medical devices. Exam questions will present genuine engineering dilemmas – for instance, designing a lightweight wheelchair ramp or a solar-powered water pump for an off‑grid community.
2026年教学大纲嵌入了来自航空航天、可再生能源和医疗器械等领域的真实案例研究。考试题目将呈现真实的工程困境，例如设计轻便的轮椅坡道或为偏远社区设计太阳能水泵。
To tackle these, students must break complex problems into sub‑systems, identify constraints (cost, mass, safety standards), and apply a systematic design process. Tools such as Pugh matrices and decision matrices are explicitly recommended for evaluating multiple design options.
为解决这些问题，学生必须将复杂问题分解为子系统，识别限制条件（成本、质量、安全标准），并应用系统化的设计过程。明确推荐使用Pugh矩阵和决策矩阵等工具来评估多个设计方案。
8. Enhanced Focus on Materials and Manufacturing | 对材料和制造的加强关注
The materials section now includes smart materials like shape memory alloys and piezoelectric ceramics, alongside advanced composites such as carbon fibre reinforced polymer (CFRP). Learners must compare traditional and modern materials using properties like specific stiffness, toughness, and corrosion resistance.
材料部分现在包括形状记忆合金和压电陶瓷等智能材料，以及碳纤维增强聚合物（CFRP）等先进复合材料。学习者必须使用比刚度、韧性和耐腐蚀性等性能来比较传统与现代材料。
Manufacturing processes embrace automation, robotics, and just‑in‑time production. Statistical process control (SPC) appears in the syllabus for the first time, and exam questions may ask candidates to interpret a control chart and explain how tolerances affect assembly quality.
制造工艺涵盖了自动化、机器人技术和准时生产。统计过程控制（SPC）首次出现在大纲中，考试问题可能要求考生解读控制图并解释公差如何影响装配质量。
9. Incorporation of Systems and Control | 系统与控制内容的纳入
A major new strand is the formal study of systems and control. The syllabus covers open‑loop and closed‑loop control, common sensors (thermistors, LDRs, potentiometers), actuators, and programmable microcontrollers. Students are expected to design simple control algorithms using flowcharts or pseudocode.
一个重要的新主线是对系统与控制的正式学习。大纲涵盖了开环和闭环控制、常见传感器（热敏电阻、光敏电阻、电位器）、执行器以及可编程微控制器。要求学生使用流程图或伪代码设计简单的控制算法。
Examination tasks may present a faulty control circuit or a misbehaving automated system and ask for a logical diagnosis. For example, a thermistor‑based temperature regulator might behave erratically; candidates must identify whether the sensor, comparator, or output stage is at fault.
考试任务可能会给出一个故障的控制电路或一个失常的自动化系统，并要求进行逻辑诊断。例如，基于热敏电阻的温度调节器可能工作不稳定；考生必须判断是传感器、比较器还是输出级出现了问题。
10. Revision Tips for 2026 Onwards | 2026年及以后的复习建议
Revise with a deliberate focus on AO3 – practise designing solutions rather than just rewriting notes. Use the specimen papers released by Cambridge and set yourself timed challenges where you design a product against a brief. Build a portfolio of case studies that cover sustainability, materials, and digital manufacturing.
复习时有意识地聚焦于AO3——练习设计解决方案，而不仅仅是抄写笔记。使用剑桥发布的样卷，并为自己设定限时挑战，根据任务书设计产品。建立一个涵盖可持续性、材料和数字制造的案例研究作品集。
For the NEA, start early and maintain a meticulous logbook. Seek feedback after each design iteration and document how you acted on it. For systems and control, hands‑on practice with a microcontroller like Arduino and basic sensor circuits will deepen your understanding far beyond textbook theory.
对于NEA，应尽早开始并保持细致的日志。在每次设计迭代后寻求反馈，并记录你是如何根据反馈优化的。对于系统与控制，亲手使用Arduino等微控制器和基本传感器电路进行实践，将使你的理解远超课本理论。
11. Trends in Grading and Assessment | 评分和评估趋势
After post‑pandemic volatility, grade boundaries for the 2026 series are expected to stabilise. However, attaining the highest grades (8 or 9) will demand consistent critical analysis, innovative flair, and crystal‑clear communication in both written work and NEA documentation.
疫情后的波动过后，2026年系列的分数线预计将趋于稳定。然而，获得最高等级（8或9）将要求在书面作业和NEA文档中持续展现批判性分析、创新天赋和清晰明了的沟通。
