剑桥IGCSE工程（0445）资格考试将从2026年考试系列起经历重大变革。这些更新响应了制造业、可持续发展和数字化设计的快速变化，旨在让学生掌握与现代工程行业直接相关的技能。所有考生、教师和家长都应了解修订后的课程结构、评估形式及新增内容侧重点，以便有效备考。
1. Why the Syllabus is Changing | 教学大纲为何改变
Cambridge International has redesigned the Engineering syllabus to better reflect current industry standards and the competencies required for further study. The previous model, which relied heavily on teacher-assessed coursework, often led to inconsistent grading and limited the scope of practical skills tested under controlled conditions.
剑桥国际重新设计了工程教学大纲，以更好地反映当前的行业标准以及进一步学习所需的能力。旧版模式高度依赖教师评估的课程作业，常常导致评分不一致，并限制了在受控条件下测试实践技能的范围。
Employers and universities have highlighted a growing need for engineers who are proficient in problem-solving, digital modelling, and sustainable design rather than merely workshop fabrication. The 2026 syllabus addresses these needs by placing these capabilities at the core of the assessment.
雇主和大学都强调，越来越需要擅长解决问题、数字建模和可持续设计的工程师，而不仅仅是车间制造。2026年的教学大纲将这些能力置于评估的核心位置，从而回应了这些需求。
Additionally, the global shift towards net-zero carbon targets has made environmental engineering principles essential. The updated curriculum integrates life cycle thinking and renewable energy systems throughout the course.
此外，全球向净零碳排放目标转变的趋势使得环境工程原理变得至关重要。更新后的课程将生命周期思维和可再生能源系统贯穿始终。
2. Key Changes to Assessment Structure | 评估结构的关键变化
The most visible difference is the removal of the school-based coursework component and its replacement with an externally set, timed practical examination. This ensures that every candidate is assessed under identical conditions and that practical skills are measured with greater reliability.
最明显的区别是取消了校内课程作业部分，取而代之的是由外部设定、限时完成的实践考试。这样能确保每位考生在相同条件下接受评估，并使实践技能的衡量更加可靠。
The new syllabus consists of two compulsory papers, both sat in the same examination series. The following table compares the old and new structures:
新教学大纲由两份必考试卷组成，两者在同一考试系列中进行。下表比较了旧版与新版的结构：
| Component | Pre-2026 | From 2026 |
|---|---|---|
| Paper 1 | Theory (1 h 30 min, 50%) | Product Design and Engineering Principles (2 h, 50%) |
| Paper 2 | Coursework (50%) | Practical Engineering Test (2 h 30 min, 50%) |
The written paper now extends to 2 hours and includes longer design-context questions requiring extended responses. Marks are allocated for reasoning, justification, and evaluation, not just factual recall.
笔试现在延长至2小时，并包含要求扩展作答的设计情境题。分数不仅分配给事实回忆，还分配给推理、论证和评估。
The practical exam is conducted at the candidate's centre but under strict supervision, with materials and tasks provided by Cambridge. Candidates must complete a series of engineering operations, demonstrate measurement accuracy, and evaluate their own processes.
实践考试在考生所在中心进行，但受到严格监督，材料和任务由剑桥提供。考生必须完成一系列工程操作，展示测量精度，并评估自己的制作过程。
3. From Coursework to Timed Practical Examination | 从课程作业到限时实践考试
Under the old system, the coursework portfolio allowed students to work on an extended project over many weeks. While this encouraged craftsmanship, it often involved significant teacher input and was susceptible to plagiarism. The new practical test removes these inconsistencies.
在旧体系下，课程作业作品集允许学生在数周内完成一个扩展项目。虽然这鼓励了工艺制作，但往往涉及大量教师指导且容易受到抄袭影响。新的实践测试消除了这些不一致。
The 2-hour-30-minute practical exam will assess a predefined set of skills such as marking out, cutting, forming, joining, and finishing with specified tolerances. Candidates also answer short written questions about the process, evaluating quality and suggesting improvements.
这场2小时30分钟的实践考试将评估一组预设技能，如划线、切割、成型、连接以及在给定公差范围内完成精加工。考生还需回答关于制作过程的简短书面问题，评估质量并提出改进建议。
Teachers will still prepare students through regular hands-on workshops, but the final mark is awarded solely based on the exam-day performance, giving a fairer comparison across centres worldwide.
教师仍会通过常规动手工坊为学生做准备，但最终评分完全基于考试当天的表现，这使得全球各中心之间的比较更加公平。
4. New Content: Sustainability and Smart Materials | 新增内容：可持续性与智能材料
Sustainability is no longer a marginal topic; it is woven into every section of the syllabus. Students must now analyse the environmental impact of materials from extraction to disposal, using tools such as life cycle assessment (LCA).
可持续性不再是一个边缘话题，它已融入教学大纲的每一部分。学生现在必须使用生命周期评估（LCA）等工具，分析材料从开采到处置的环境影响。
The syllabus explicitly introduces the 6Rs of sustainability: Reduce, Reuse, Recycle, Repair, Refuse, and Rethink. Design questions will require candidates to apply these principles to product development.
大纲明确引入了可持续性的6R原则：减量（Reduce）、复用（Reuse）、回收（Recycle）、修复（Repair）、拒绝（Refuse）和重新思考（Rethink）。设计题将要求考生将这些原则应用于产品开发。
Smart materials and modern composites are now mandatory knowledge. Candidates should be familiar with shape memory alloys (SMA), thermochromic pigments, piezoelectric materials, and carbon fibre reinforced polymers. The following table summarises key smart materials and their applications:
智能材料和现代复合材料如今是必修知识。考生应熟悉形状记忆合金（SMA）、热致变色颜料、压电材料和碳纤维增强聚合物。下表总结了关键的智能材料及其应用：
| Smart Material | Property | Typical Application |
|---|---|---|
| Shape Memory Alloy (Nitinol) | Returns to original shape when heated | Actuators, orthodontic wires, stents |
| Thermochromic Pigment | Changes colour with temperature | Mood rings, battery indicators, baby spoons |
| Piezoelectric Material | Generates voltage under mechanical stress | Sensors, energy harvesting, ultrasound |
| Carbon Fibre Reinforced Polymer | High strength-to-weight ratio | Aerospace, sports equipment, automotive |
Renewable energy technologies also feature, including photovoltaic cells, wind turbine design, and energy storage systems. Calculations involving energy efficiency and power output may appear in the written paper.
可再生能源技术也被纳入，包括光伏电池、风力涡轮机设计和能源存储系统。涉及能效和功率输出的计算可能会出现在笔试中。
5. Integrated Engineering Design Process | 整合的工程设计流程
The 2026 syllabus places much greater emphasis on the iterative design process, modelled on real-world engineering practices. Students must be able to move from problem identification through research, specification, conceptual design, modelling, and testing to final evaluation.
2026年的教学大纲更加重视迭代设计流程，该流程以现实世界的工程实践为模板。学生必须能够从问题识别，经过研究、规格说明、概念设计、建模和测试，最终完成评估。
Rather than simply producing a final artefact, candidates are asked to document how their design decisions are informed by client feedback, ergonomic data, and sustainability criteria. Written exam questions will present a design scenario and require learners to critique a proposed solution.
考生不仅仅需要制作一个最终制品，还会被要求记录他们的设计决策是如何根据客户反馈、人体工学数据和可持续性标准做出的。笔试题会呈现一个设计情境，要求学习者批判性地评价所提出的解决方案。
The practical exam also embeds this process: one station might ask candidates to measure a component and suggest a redesign to improve its strength-to-weight ratio, justifying their reasoning with calculations. This mirrors the 'evaluate and optimise' stage of the engineering cycle.
实践考试也嵌入了这一流程：一个考站可能会要求考生测量一个组件，并建议重新设计以提高其强度重量比，同时通过计算来论证其推理。这反映了工程循环中的“评估与优化”阶段。
6. Digital Skills: CAD and CAM Integration | 数字技能：CAD 与 CAM 的整合
Computer-aided design (CAD) and computer-aided manufacturing (CAM) are no longer optional enrichment topics. The syllabus explicitly requires students to demonstrate understanding of 2D and 3D CAD modelling and the translation of digital designs to machine instructions.
计算机辅助设计（CAD）和计算机辅助制造（CAM）不再是可选的拓展主题。教学大纲明确要求学生展示对2D和3D CAD建模的理解，以及将数字设计转化为机器指令的能力。
In the written paper, candidates may be given a set of orthographic views and asked to identify the corresponding 3D CAD model, or they might explain how a laser cutter raster and vector settings differ. Practical tasks may involve interpreting a CAD-generated drawing to manufacture a part within tolerance.
在笔试中，考生可能会得到一组正投影视图，并要求识别相应的3D CAD模型，或者解释激光切割机的光栅和矢量设置有何不同。实践任务可能涉及解读CAD生成的图纸，以在公差范围内加工出零件。
CAM knowledge now extends to rapid prototyping technologies like 3D printing (FDM and SLA), CNC machining, and robotic assembly. Students should be comfortable comparing additive and subtractive manufacturing processes in terms of waste, speed, and cost.
CAM知识现在扩展到快速原型技术，如3D打印（FDM和SLA）、CNC加工和机器人装配。学生应能熟练地从废料、速度和成本方面比较增材制造与减材制造工艺。
7. Revised Assessment Objectives and Mark Allocation | 修订的评估目标与分数分配
Assessment weightings have been recalibrated to give more importance to higher-order thinking skills. The three Assessment Objectives (AOs) are now defined as:
评估权重经过重新校准，更加重视高阶思维技能。三项评估目标（AO）现在定义如下：
| AO | Description | Approximate Weighting |
|---|---|---|
| AO1 | Recall, select, and communicate engineering knowledge | 30% |
| AO2 | Apply knowledge, techniques, and processes to solve problems | 40% |
| AO3 | Analyse, evaluate, and justify engineering solutions | 30% |
Compared to the previous syllabus, AO3 has increased significantly. Command words such as 'evaluate', 'justify', 'critically assess', and 'recommend' will appear more frequently. Students must practise constructing well-reasoned arguments supported by quantitative evidence.
与之前的大纲相比，AO3的权重明显增加。“评估”、“论证”、“批判性评价”和“推荐”等指令词将更频繁地出现。学生必须练习构建有充分推理且以定量证据支持的论证。
In practical exams, marks are awarded not only for dimensional accuracy but also for the clarity of process evaluation. For example, after cutting a joint, a candidate might write about how to reduce kerf width and improve finish, which directly tests AO3.
在实践考试中，分数不仅授予尺寸精度，还授予流程评价的清晰度。例如，在切割一个接头后，考生可能会写如何减小切口宽度和改善表面光洁度，这直接测试了AO3。
8. Mathematical Requirements and Engineering Calculations | 数学要求与工程计算
Numeracy remains fundamental. The 2026 syllabus expects candidates to confidently handle unit conversions, ratios, percentages, and standard form. Specific engineering formulas will be provided on the question paper where needed, but students must know how to apply them.
计算能力仍然是基础。2026年教学大纲期望考生能自信地处理单位换算、比率、百分数和标准形式。特定的工程公式将在需要时提供在试卷上，但学生必须知道如何应用它们。
Key equations include stress and strain calculations: direct stress σ = F ÷ A, where σ is measured in pascals (Pa), force F in newtons (N), and cross-sectional area A in m². Strain ε is dimensionless: ε = ΔL ÷ L₀, the change in length over the original length.
关键方程包括应力和应变计算：正应力 σ = F ÷ A，其中 σ 以帕斯卡（Pa）为单位，力 F 以牛顿（N）为单位，横截面积 A 以 m² 为单位。应变 ε 无量纲：ε = ΔL ÷ L₀，即长度变化量除以原始长度。
= distance moved by effort ÷ distance moved by load), and efficiency (η = (MA ÷ VR) × 100%). A clear grasp of trigonometry is needed for resolving forces in simple frameworks.
考生还可能遇到机械利益（MA = 负载 ÷ 动力）、速度比（VR = 动力移动距离 ÷ 负载移动距离）和效率（η = (MA ÷ VR) × 100%）。需要清晰的三角学知识来分解简单框架中的力。
9. Implications for Teaching and Centre Preparation | 对教学与中心准备的影响
Schools and tutorial centres will need to update their workshop facilities to provide the range of materials and processes specified in the new practice tasks. Cambridge has published a list of recommended tools and equipment to ensure parity across centres.
学校和辅导中心需要更新其工坊设施，以提供新的实践活动所规定的一系列材料和工艺。剑桥已发布了一份推荐工具与设备清单，以确保各中心之间的一致性。
Teacher professional development is crucial, particularly in the areas of CAD/CAM and sustainability. Many engineering teachers come from traditional manufacturing backgrounds and may require retraining to confidently deliver computer-integrated manufacturing concepts.
教师专业发展至关重要，尤其是在CAD/CAM和可持续发展领域。许多工程教师具有传统制造背景，可能需要再培训才能自信地教授计算机集成制造概念。
Internal assessment tracking must now focus on time-bound practical skills rather than extended projects. Mock practical exams under exam conditions will be essential to familiarise students with the pressure and time constraints of the 2.5-hour test.
内部评估跟踪现在必须侧重于限时实践技能，而非扩展项目。在考试条件下进行模拟实践考试，对于让学生熟悉2.5小时测试的压力和时间限制至关重要。
10. Global Trends in Engineering Education | 工程教育的全球趋势
The changes to Cambridge IGCSE Engineering mirror broader shifts in engineering pedagogy worldwide. UNESCO's Engineering Report highlights the need for curricula that foster creativity, teamwork, and ethical reasoning alongside technical proficiency.
剑桥IGCSE工程的变化反映了全球工程教学法的更广泛转变。联合国教科文组织的工程报告强调，课程需要在培养技术能力的同时，培养创造力、团队合作和伦理推理。
STEM integration is increasing: the new syllabus explicitly links scientific principles from physics and chemistry to engineering contexts. For example, understanding oxidation is now tied to material selection for outdoor structures rather than being treated as an isolated chemistry fact.
STEM融合正在加强：新大纲明确将物理和化学的科学原理与工程情境联系起来。例如，对氧化的理解现在与户外结构的材料选择相关联，而不是作为孤立的化学事实。
Project-based learning (PBL) remains the recommended classroom approach, even though the final assessment is exam-based. Teachers are encouraged to use mini design challenges to build the analytical and evaluative skills needed for AO3.
尽管最终评估以考试为主，但项目式学习（PBL）仍然是推荐的课堂教学方法。鼓励教师使用小型设计挑战来培养学生所需的分析和评估技能，以应对AO3。
The rise of artificial intelligence in engineering design is acknowledged, with the syllabus encouraging students to discuss the ethical implications of automated systems and data-driven decision-making. This prepares learners for future careers where AI tools are ubiquitous.
