2. Revised Assessment Structure | 修订后的评估结构
The weighting of examination components has been rebalanced to increase the value of theoretical understanding while maintaining a strong practical core. The table below compares the old and new weightings, highlighting the increased proportion for coursework and the adjusted role of Paper 2.
考试组成部分的权重已重新平衡，既提高了理论理解的分值，又维持了扎实的实践核心。下表对比了新旧权重，突出课程作业比例的增加和试卷 2 角色的调整。
| Component | Weighting up to 2025 | Weighting from 2026 |
|---|---|---|
| Paper 1: Engineering Fundamentals | 35% | 40% |
| Paper 2: Engineering in Practice | 40% | 30% |
| Coursework: Design & Make Project | 25% | 30% |
Paper 1 now carries 40% and has been extended to a 2-hour 30-minute written paper with 90 marks. The increased depth tests core principles such as mechanics, materials and electronics more rigorously. Paper 2 drops to 30% but becomes a highly applied problem-solving paper that integrates mathematical modelling, CAD interpretation and systems analysis. The coursework component rises to 30%, requiring a more substantial design-and-make project with digital evidence.
试卷 1 现在占 40%，已延长为 2 小时 30 分钟、总分 90 分的笔试。加强的深度更严格地考查力学、材料和电子学等核心原理。试卷 2 降至 30%，但变成一门高度应用性的问题解决试卷，融合了数学建模、CAD 解读和系统分析。课程作业部分升至 30%，要求学生完成更有分量的设计和制作项目，并提交数字作品作为证据。
3. Paper 1: Enhanced Engineering Theory | 试卷1：增强的工程理论
The renewed Paper 1 introduces contemporary topics that reflect the direction of modern industry. Learners must now study renewable energy systems, including photovoltaic cells, wind turbine mechanics and energy storage. The syllabus also formalises coverage of microcontrollers and programmable logic, with questions asking students to interpret simple flowcharts and control algorithms using symbols and pseudocode.
更新后的试卷 1 引入了反映现代工业方向的当代课题。学习者现在必须学习可再生能源系统，包括光伏电池、风力涡轮机力学和能量储存。教学大纲还正式涵盖了微控制器和可编程逻辑，题目要求学生使用符号和伪代码解读简单的流程图和控制算法。
Additionally, questions on engineering mathematics will require the application of trigonometric functions, logarithms and calculus to authentic engineering contexts. For instance, a problem might ask students to determine the optimum angle of a solar panel using sin θ and cos θ relationships or to calculate energy dissipated in a damper using integration. The use of standard scientific notation and SI units is mandated throughout.
此外，工程数学题将要求将三角函数、对数和微积分应用于真实的工程情境。例如，一道题可能要求学生利用 sin θ 和 cos θ 关系确定太阳能电池板的最佳角度，或用积分计算阻尼器中耗散的能量。全程规定使用标准科学记数法和国际单位制。
4. Paper 2: Applied Problem-Solving and Modelling | 试卷2：应用性问题解决与建模
Paper 2 has been redesigned to move away from a simple extension of theory towards a genuine simulation of engineering practice. Examination questions now provide data sheets, 2D and 3D CAD sketches, and system diagrams, requiring candidates to extract information, perform calculations and propose design modifications.
试卷 2 已重新设计，不再是对理论的简单延伸，而是真正模拟工程实践。考试题目现在会提供数据表、二维和三维 CAD 草图以及系统图，要求考生提取信息、进行计算并提出设计修改方案。
Mathematical modelling plays a central role. Kinetic and kinematic analysis may involve equations such as v = u + at and F = m × a, as well as energy methods using E = ½ × m × v². Candidates might need to calculate the force required to lift a load using a lead screw, applying T = (F × p) / (2π × η), where p is the pitch and η the efficiency. These are presented in a context-rich format that mimics real engineering briefs.
数学建模起着核心作用。运动学和动力学分析可能涉及 v = u + at 和 F = m × a 等方程，以及用 E = ½ × m × v² 的能量法。考生可能需要运用 T = (F × p) / (2π × η) 计算丝杠举升负载所需的扭矩，其中 p 为螺距，η 为效率。这些题目以模拟真实工程简报的丰富情境形式呈现。
5. Coursework Reform: The New Design and Make Project | 课程作业改革：新的设计与制作项目
The coursework component has been transformed into a more structured and digitally documented project. Students must identify a genuine user need, carry out research, generate a design specification, and produce a working prototype using a combination of traditional and digital manufacturing techniques. The project must now include a cad model, CAM toolpaths and a final physical artefact with a detailed evaluation of its performance against the specification.
课程作业部分已转变为一个更有条理、且需要数字记录的项目。学生必须识别真实的用户需求、开展调研、生成设计规格，并结合传统和数字制造技术制作一个可工作的原型。项目现在必须包含 CAD 模型、CAM 刀具路径和最终的实物成品，并对照规格对其性能进行详细评估。
Assessment criteria now place explicit weight on sustainability, innovation and functionality. Evidence of iterative design is essential: learners must show how testing and user feedback led to modifications. The use of finite element analysis (FEA) or simple simulation for stress distribution is encouraged but not mandatory; nonetheless, the syllabus expects students to discuss basic stress-strain relationships using σ = F / A and ε = ΔL / L₀ within their report.
评估标准现在明确把权重放在可持续性、创新性和功能性上。迭代设计的证据至关重要：学习者必须展示测试和用户反馈如何促成修改。鼓励但不强制使用有限元分析或简单仿真来分析应力分布；不过，教学大纲期望学生在报告中运用 σ = F / A 和 ε = ΔL / L₀ 讨论基本的应力-应变关系。
6. Increased Emphasis on Digital Skills and CAD/CAM | 对数字技能与 CAD/CAM 的更强调
From 2026, digital competence is no longer an optional enrichment but a core requirement. Schools and candidates must be proficient in at least one parametric 3D CAD package, such as Fusion 360 or SolidWorks, to produce design files that can be exported for 3D printing, laser cutting or CNC machining. The syllabus mandates that coursework submissions include original .STL or .STEP files alongside rendered images.
从 2026 年起，数字能力不再是可选拓展，而是一项核心要求。学校和考生必须精通至少一款参数化三维 CAD 软件（如 Fusion 360 或 SolidWorks），能够生成可导出用于 3D 打印、激光切割或 CNC 加工的设计文件。教学大纲规定，课程作业提交材料中必须包含原始 .STL 或 .STEP 文件以及渲染图像。
Computer-aided manufacture (CAM) is also integrated into the curriculum. Students learn to generate G-code for milling or turning operations and understand the relationship between cutting speed, feed rate and surface finish. The examination might present a simple G-code block such as G01 X50 Y25 F100 and ask candidates to interpret the motion. Familiarity with coordinate systems and tool offsets thus becomes essential.
计算机辅助制造也已融入课程。学生学习为铣削或车削操作生成 G 代码，并理解切削速度、进给率和表面光洁度之间的关系。考试可能给出一段简单的 G 代码（如 G01 X50 Y25 F100），要求考生解读运动路径。因此，熟悉坐标系和刀具补偿变得至关重要。
7. Sustainability and Green Engineering | 可持续发展与绿色工程
Sustainability is woven throughout the new syllabus, reflecting global imperatives and the UN Sustainable Development Goals. Topics include life cycle assessment (LCA), embodied energy, carbon footprinting and the circular economy. Candidates must be able to evaluate materials and processes from an environmental perspective, not just a technical one.
可持续发展贯穿于整个新大纲，反映了全球紧迫议程和联合国可持续发展目标。课题包括生命周期评估、蕴含能、碳足迹和循环经济。考生必须能够从环境角度而不仅仅是技术角度评估材料和工艺。
The coursework project now demands a sustainability statement, explaining how material selection minimises environmental impact. For example, using recycled aluminium rather than virgin material can reduce embodied energy by up to 95%. In the written papers, questions might ask students to calculate the CO₂ emissions saved by switching from injection-moulded ABS to PLA bio-plastic, given emission factors in kg CO₂ per kg material. Such calculations reinforce the use of scientific analysis in green design.
课程作业项目现在要求提供一份可持续发展声明，解释材料选择如何将环境影响降至最低。例如，使用再生铝而非原生材料可将蕴含能减少高达 95%。在笔试中，题目可能要求学生在给定每千克材料 CO₂ 排放因子的情况下，计算从注塑 ABS 更换为 PLA 生物塑料所节省的 CO₂ 排放量。这类计算强化了科学分析在绿色设计中的运用。
8. Materials Science and Smart Materials | 材料科学与智能材料
The materials topic has been expanded beyond traditional ferrous and non-ferrous alloys to include advanced functional materials. Shape memory alloys (SMAs) such as NiTi are now core content, with emphasis on the phase transformation between austenite and martensite. Piezoelectric ceramics like lead zirconate titanate (PZT, Pb(Zr,Ti)O₃) are examined for sensor and actuator applications.
材料课题已经扩展，不仅涵盖传统铁合金和非铁合金，还包含了先进功能材料。形状记忆合金（如 NiTi）现已成为核心内容，重点是马氏体和奥氏体之间的相变。锆钛酸铅压电陶瓷（PZT, Pb(Zr,Ti)O₃）则因其在传感器和致动器中的应用而被考查。
Composites and nanomaterials are also introduced. Students must be able to compare the specific strength of carbon fibre reinforced polymer (CFRP) with that of steel; calculations might involve dividing tensile strength by density, yielding values in MPa·m³/kg. The syllabus encourages an understanding of how material structure, processing and properties are interrelated, often represented by the familiar triangle of processing–structure–properties.
复合材料和纳米材料也同样引入。学生必须能够比较碳纤维增强聚合物与钢的比强度；计算可能涉及用拉伸强度除以密度，结果以 MPa·m³/kg 表示。教学大纲鼓励理解材料结构、加工和性能的相互关系，这通常以加工—结构—性能三元关系图来表示。
9. Integration of Systems and Control | 系统与控制的整合
The new syllabus takes a systems engineering approach, requiring learners to understand not just individual components but how they interact in functional systems. Topics such as open-loop and closed-loop control, feedback, sensors (thermistors, LDRs, strain gauges) and actuators (stepper motors, solenoids) are examined in far greater depth than before.
新教学大纲采用系统工程的方法，不仅要求学习者理解单个元件，还要求理解它们如何在功能系统中相互作用。开环和闭环控制、反馈、传感器（热敏电阻、光敏电阻、应变片）以及执行器（步进电机、电磁铁）等内容比以前考查得更深。
Block diagrams are central to Paper 2, where candidates may be asked to derive the overall transfer function of a simple system. For a series connection, the result is G_total = G₁ × G₂. Although rigorous Laplace transforms are not required, students must grasp proportional, integral and derivative (PID) concepts qualitatively and be able to tune a control loop using terms such as Kₚ, Kᵢ and K_d. Microntroller programming is also tested through flowcharts that control temperature or position.
方块图是试卷 2 的核心，考生可能被要求推导简单系统的总体传递函数。对于串联连接，结果是 G_total = G₁ × G₂。虽然不要求严格的拉普拉斯变换，但学生必须定性地掌握比例、积分和微分（PID）概念，并能够使用 Kₚ、Kᵢ 和 K_d 等术语调节控制回路。微控制器编程也通过控制温度或位置的流程图来考查。
10. Emerging Trends: Interdisciplinary Links | 发展趋势：跨学科联系
A notable trend in the 2026 assessment model is the deliberate blurring of boundaries between engineering, physics and computer science. Candidates see questions that assume knowledge of thermodynamics from physics, alongside programming logic from computer science. This interdisciplinary approach is designed to reflect the reality of modern engineering careers.
2026 年评估模式的一个显著趋势是有意识地模糊工程、物理和计算机科学之间的界限。考生会碰到既需要物理热力学知识、又需要计算机科学编程逻辑的题目。这种跨学科方法旨在反映现代工程职业的真实情况。
For instance, a problem might describe a robotic arm where kinematics relies on θ(t) = ωt + ½αt² and the control algorithm is presented in a Python-like pseudocode. Students must extract mechanical parameters, interpret the code and adjust gains to avoid overshoot. Such tasks reward flexible thinking and reinforce the importance of cross-curricular competence.
例如，一道题可能描述一个机械臂，其运动学依赖 θ(t) = ωt + ½αt²，控制算法以类 Python 的伪代码给出。学生必须提取机械参数、解读代码并调节增益以避免超调。这类任务奖励灵活思维，并强化了跨学科能力的重要性。
11. Preparation Strategies for the 2026 Examination | 2026年考试备考策略
To succeed in the revised examination, students should build a broad engineering vocabulary in English, as both the question papers and coursework reports require precise technical communication. Regular practice with past papers remains vital, but candidates must also seek out specimen materials released specifically for the 2025–2027 syllabus, as these reflect the new question styles and command words.
要在修订后的考试中取得成功，学生应积累广泛的工程英语词汇，因为试卷和课程报告都要求精确的技术表达。常规真题练习依然至关重要，但考生还必须寻找专门针对 2025–2027 大纲发布的样题材料，因为它们反映了新的题型和指令词。
Practical workshop time should be increased to develop familiarity with hand tools, CNC equipment and 3D printers. Students are advised to keep a digital design journal from the start of the course, documenting every iteration and linking decisions to engineering principles. Finally, connecting with online communities, such as the TutorHao revision platform, can provide structured revision notes, topic tests and expert guidance tailored to the CIE Engineering specification.
应增加实践车间时间，以熟悉手动工具、CNC 设备和 3D 打印机。建议学生从课程伊始就保持数字设计日志，记录每次迭代并把决策与工程原理联系起来。最后，通过在线社区（如 TutorHao 复习平台）联系，能够获得针对 CIE 工程规范的体系化复习笔记、主题测试和专家指导。
