1. Qualification Overview | 资格概述
The Eduqas GCSE (9-1) in Engineering is composed of two mandatory components. Component 1, Engineering Design, is a written examination lasting 2 hours, contributing 50% of the overall grade and carrying 120 marks. Component 2, Engineering Manufacture, is a non-exam assessment (NEA) that also accounts for 50% of the qualification, requiring learners to produce a design portfolio and a completed practical product.
Eduqas GCSE（9-1）工程资格由两个必修部分组成。第一部分是工程设计，为2小时的书面考试，占总成绩的50%，满分为120分。第二部分是工程制造，属于非考试评估（NEA），同样占总成绩的50%，要求学生提交设计作品集和一件完成的实物产品。
Candidates are assessed against four Assessment Objectives: AO1 covers recall and understanding of engineering principles; AO2 involves application of knowledge to real-world contexts; AO3 requires analysis and evaluation of products and processes; and AO4 focuses on practical making skills and iterative design. The written paper mainly tests AO1-AO3, while the NEA evidences all objectives, especially AO4.
考生将对照四个评估目标进行评价：AO1涵盖对工程原理的记忆与理解；AO2涉及将知识应用于现实场景；AO3要求分析评估产品和过程；AO4则侧重动手制作技能和迭代设计。书面考试主要考查AO1至AO3，而NEA则展示所有目标，特别是AO4的表现。
2. Engineering Design Process | 工程设计流程
At the heart of the syllabus lies the iterative design cycle, which students apply both in the exam and during their NEA. The process begins with identifying a genuine problem or user need, followed by in-depth research into existing solutions, target users, and relevant technologies. This informs the development of a clear design brief and technical specification.
课程大纲的核心是迭代设计循环，学生在考试和NEA中都需要应用它。该过程从识别真实问题或用户需求开始，随后深入研究现有解决方案、目标用户和相关技术。这为制定明确的设计概要和技术规格奠定了基础。
Learners generate a range of initial ideas through sketching and CAD modelling, then select and develop the most promising concept. Detailed designs are produced using formal drawing conventions, such as orthographic and isometric projections, and often include 3D CAD models. Prototyping, whether with card, 3D printing or other rapid methods, enables real-world testing and refinement before final manufacture.
学习者通过草图绘制和CAD建模产生一系列初始想法，然后选择并发展最有前景的方案。详细设计需遵循正式工程制图规范，如正投影和等轴测图，通常还包含三维CAD模型。无论是用纸板、3D打印还是其他快速方法制作的原型，都能在最终制造之前进行实际测试和改进。
Risk assessment is integral to the design planning, covering both workshop safety during production and potential hazards associated with the product in use. The design folder produced for the NEA must demonstrate how the iterative cycle has been followed, from concept to refined final outcome.
风险评估是设计规划中不可或缺的部分，既涵盖生产过程中的车间安全，也包括产品使用中的潜在危险。为NEA制作的设计文件夹必须展示从概念到改进后最终成果的整个迭代循环过程。
3. Material Properties and Selection | 材料性能与选择
Engineers must select materials based on their mechanical, physical, and thermal properties. The syllabus covers key categories: ferrous metals (e.g. mild steel, cast iron), non-ferrous metals (e.g. aluminium, copper), alloys (e.g. stainless steel), thermoplastics (e.g. ABS, acrylic), thermosetting plastics (e.g. epoxy resin), elastomers, composites (e.g. carbon fibre reinforced polymer), woods and ceramics.
工程师必须根据材料的力学、物理和热学性能进行选材。大纲涵盖关键类别：黑色金属（如低碳钢、铸铁）、有色金属（如铝、铜）、合金（如不锈钢）、热塑性塑料（如ABS、亚克力）、热固性塑料（如环氧树脂）、弹性体、复合材料（如碳纤维增强聚合物）、木材和陶瓷。
Important properties include tensile strength, compressive strength, hardness, toughness, ductility, elasticity, density, thermal conductivity, electrical conductivity and corrosion resistance. Students learn how these properties are determined through standard tests, such as the tensile test, which measures yield strength, ultimate tensile strength and elongation.
重要的性能包括抗拉强度、抗压强度、硬度、韧性、延展性、弹性、密度、导热性、导电性和耐腐蚀性。学生会了解这些性能如何通过标准试验测定，例如拉伸试验可测量屈服强度、极限抗拉强度和伸长率。
Material selection is always contextual: a smartphone casing might require lightweight, impact-resistant plastic, while a bridge beam demands high tensile strength in steel. Cost, availability, environmental impact and recyclability increasingly influence decisions alongside pure technical performance.
选材始终取决于具体场景：智能手机外壳可能需要轻质、抗冲击的塑料，而桥梁大梁则要求钢材具有高抗拉强度。除了纯粹的技术性能，成本、可获得性、环境影响和可回收性也越来越影响决策。
4. Manufacturing Processes and Techniques | 制造工艺与技术
The specification explores a wide range of manufacturing processes used in both workshop and industrial settings. For metals, these include sand casting, die casting, turning, milling, drilling, laser cutting and various welding techniques. Polymers can be shaped by injection moulding, extrusion, blow moulding, thermoforming (vacuum forming) and 3D printing, which is increasingly common in school workshops.
大纲探讨了在车间和工业环境中使用的多种制造工艺。金属方面，包括砂型铸造、压铸、车削、铣削、钻孔、激光切割和各种焊接技术。聚合物可通过注塑成型、挤出、吹塑、热成型（真空成型）和3D打印进行成形，3D打印正越来越多地出现在学校车间中。
Additive manufacturing (3D printing) is often used for rapid prototyping, while subtractive methods such as CNC machining provide high precision for final production. Students must understand the advantages and limitations of each process, including surface finish, achievable tolerances, production volume and cost. Assembly techniques like fasteners, adhesives and snap-fits are also covered.
增材制造（3D打印）常用于快速原型制作，而CNC加工等减材方法则为最终生产提供高精度。学生必须理解每种工艺的优缺点，包括表面光洁度、可达公差、产量和成本。课程还涵盖紧固件、粘合剂和卡扣配合等组装技术。
Hand tools and bench skills remain important, especially for the NEA. Learners practise marking out, cutting, filing, drilling and finishing by hand before moving to machines. Safe working practices are emphasised throughout, with competence in using PPE and following risk assessments being essential.
手工工具和台钳技能仍然重要，尤其是在NEA中。学习者在操作机器之前，会先练习划线、切割、挫削、钻孔和手工精整。整个过程中均强调安全工作规范，具备使用个人防护装备和遵守风险评估的能力是基本要求。
5. Electronic and Electrical Systems | 电子与电气系统
Electronics forms a critical part of modern engineering systems. The syllabus introduces fundamental quantities: current (I, measured in amperes), voltage (V, in volts) and resistance (R, in ohms). Ohm’s Law provides the central relationship:
V = I × R
电子学是现代工程系统的关键部分。课程大纲引入了基本电量：电流（I，单位为安培）、电压（V，单位为伏特）和电阻（R，单位为欧姆）。欧姆定律给出了核心关系：V = I × R。
Students calculate values in series and parallel circuits, and also learn the power equation:
P = V × I
学生计算串联和并联电路中的数值，并学习功率公式：P = V × I。
Common components studied include resistors, fixed and variable, capacitors, diodes, LEDs, transistors (as switches), relays, buzzers and electric motors. Input sensors such as light-dependent resistors (LDRs) and thermistors enable automatic response to environmental changes. Learners draw circuit diagrams using standard symbols and may design simple printed circuit boards (PCBs).
学习的常见元件包括固定和可变电阻器、电容器、二极管、发光二极管、晶体管（作开关用）、继电器、蜂鸣器和电动机。光敏电阻（LDR）和热敏电阻等输入传感器使电路能对环境变化作出自动响应。学习者使用标准符号绘制电路图，并可设计简单的印刷电路板（PCB）。
The role of microcontrollers is introduced, often using PICAXE or similar educational platforms. Students write basic flowcharts or pseudo-code to control outputs based on sensor inputs, building the foundation for embedded systems and automation.
课程还引入了微控制器的作用，常使用PICAXE或类似教学平台。学生编写基本的流程图或伪代码，以根据传感器输入控制输出，为嵌入式系统和自动化打下基础。
6. Mechanical Systems and Motion | 机械系统与运动
Mechanical principles underpin the design of machines. The syllabus covers levers (first, second and third order), linkages, gears (spur, bevel, worm and rack and pinion), pulley systems and cams. Students calculate velocity ratios and mechanical advantage for simple machines:
Mechanical Advantage (MA) = Load / Effort
机械原理是机器设计的基础。大纲涵盖杠杆（一类、二类和三类）、连杆机构、齿轮（正齿轮、锥齿轮、蜗轮蜗杆和齿轮齿条）、带轮系统和凸轮。学生计算简单机械的速度比和机械利益：机械利益（MA）= 负载 / 作用力。
For gear trains, the velocity ratio (VR) is determined by the ratio of teeth numbers, and torque changes inversely with speed. Understanding the conversion between rotary, linear, oscillating and reciprocating motion is essential, allowing learners to design mechanisms that produce the required output movement.
对于齿轮系，速度比（VR）由齿数比决定，扭矩与速度成反比变化。理解旋转运动、直线运动、摆动运动和往复运动之间的转换至关重要，这使学习者能设计出产生所需输出运动的机构。
The effects of friction and lubrication on efficiency are analysed. Basic spring and bearing systems are introduced, along with energy storage concepts. Wherever possible, calculations link mechanical theory to real products, such as bicycle gears or lifting equipment.
课程分析摩擦和润滑对效率的影响。还介绍基本的弹簧和轴承系统，以及能量储存概念。在可能的情况下，计算都会将机械理论与实际产品关联，如自行车变速器或起重设备。
7. Systems, Control, and Automation | 系统、控制与自动化
Every engineered product can be modelled as a system with inputs, processes and outputs. The syllabus distinguishes between open-loop control (no feedback) and closed-loop control, where sensors monitor output and adjust the process to maintain the desired condition. A thermostat regulating room temperature is a classic example of closed-loop feedback.
每件工程产品都可建模为一个具有输入、处理和输出的系统。大纲区分了开环控制（无反馈）和闭环控制，后者通过传感器监控输出并调整过程以维持所需状态。恒温器调节室温就是闭环反馈的经典例子。
Block diagrams and system flowcharts are used to represent systems. Students learn how signals from sensors (like thermistors or switches) are processed by logic or microcontroller circuits, which then drive actuators such as motors, solenoids or displays. The integration of electronics, programming and mechanical components is a key theme.
使用框图系统流程图来表示系统。学生了解来自传感器（如热敏电阻或开关）的信号如何由逻辑电路或微控制器电路处理，然后驱动马达、螺线管或显示器等执行器。电子、编程和机械部件的集成是一个关键主题。
In manufacturing, automation is achieved through programmable logic controllers (PLCs) and industrial robots. Learners may explore simple pick-and-place robot arms and discuss how automation improves repeatability, quality and speed while raising questions about workforce impact.
在制造中，自动化通过可编程逻辑控制器（PLC）和工业机器人实现。学习者可以探索简单的拾放式机械臂，并讨论自动化如何提高重复一致性、质量和速度，同时也引发对劳动力影响的思考。
8. Testing, Quality, and Evaluation | 测试、质量与评估
Ensuring a product meets its design specification requires rigorous testing. Dimensional accuracy is checked using vernier callipers, micrometres and go/no-go gauges. Functional testing verifies whether the product works as intended, while destructive testing determines failure limits.
确保产品符合其设计规格需要严格的测试。尺寸精度可通过游标卡尺、千分尺和通止规进行检验。功能测试验证产品是否按预期工作，而破坏性测试则确定失效极限。
Non-destructive testing (NDT) methods include visual inspection, dye penetrant, ultrasonic scanning and X-ray radiography, all of which are used in industry without harming the component. Quality control (QC) focuses on checking output against standards, whereas quality assurance (QA) builds quality into every stage of the process.
无损检测（NDT）方法包括目视检查、染料渗透、超声扫描和X射线照相，这些都在工业中应用且不损伤部件。质量控制（QC）侧重于对照标准检验产品，而质量保证（QA）则将质量融入过程的每个阶段。
Evaluation against the original design brief judges aesthetics, ergonomics, performance, sustainability and manufacturing efficiency. For the NEA, students must critically reflect on their own work and suggest improvements, evidencing the iterative nature of engineering design.
对照原始设计概要的评估，要从美学、人机工程学、性能、可持续性和制造效率等方面进行评判。在NEA中，学生必须对自己的工作进行批判性反思并提出改进建议，以证明工程设计的迭代性质。
9. Sustainability and Environmental Considerations | 可持续性与环境因素
Sustainability is embedded throughout the Eduqas syllabus. Lifecycle assessment (LCA) examines environmental impacts from raw material extraction, manufacturing, transportation, product use and end-of-life disposal or recycling. Engineers today aim to minimise the carbon footprint and energy consumption of products at every stage.
可持续性贯穿于Eduqas课程大纲之中。生命周期评估（LCA）审视从原材料提取、制造、运输、产品使用到报废处置或回收的各个阶段对环境的影响。当今工程师的目标是最大限度地降低产品在每个阶段的碳足迹和能耗。
The 6R strategy—Reduce, Reuse, Recycle, Rethink, Refuse, and Repair—provides a framework for sustainable design. For instance, designing for disassembly allows materials to be easily separated for recycling, while choosing biodegradable or recyclable polymers reduces landfill burden. Legislation such as the WEEE Directive and RoHS restricts hazardous substances and mandates electronic waste recycling.
6R策略——减少（Reduce）、重用（Reuse）、回收（Recycle）、重新思考（Rethink）、拒绝（Refuse）和修复（Repair）——为可持续设计提供了框架。例如，可拆卸设计使材料易于分离回收，而选择可生物降解或可回收的聚合物则减轻填埋负担。WEEE指令和RoHS等法规限制有害物质使用，并要求进行电子废弃物回收。
Students explore the tension between performance, cost and sustainability, recognising that the best engineering solutions balance economic viability with environmental responsibility. Topics such as renewable energy systems and smart materials are often used as case studies.
学生探究性能、成本和可持续性之间的张力，认识到最佳的工程解决方案要在经济可行性与环境责任之间取得平衡。可再生能源系统和智能材料等主题常被用作案例研究。
10. Mathematical and Scientific Applications | 数学与科学应用
Mathematics and science are not confined to a single topic but are woven across the entire qualification. Learners must be confident in calculating areas, volumes, densities, forces, moments, velocities, gear ratios, electrical power and mechanical advantage. Standard form and unit conversions (e.g. mm to m, grams to kilograms) appear routinely.
数学和科学并非局限于单一主题，而是贯穿整个资格认证。学习者必须能熟练计算面积、体积、密度、力、力矩、速度、齿轮比、电功率和机械利益。标准形式和单位换算（如毫米换米、克换千克）频繁出现。
Graphical skills include plotting and interpreting graphs like force-extension curves, which relate to Hooke’s Law:
F = k × x
图形技能包括绘制和解释力-伸长曲线等图表，这些与胡克定律相关：F = k × x。
Science principles from physics (Newton’s laws, moments, energy conversion, waves) and chemistry (corrosion, polymer structures) support engineering decisions. Trigonometry may be applied to resolve forces into components. All these applied contexts build the analytical thinking needed for the written exam and the technical justification within the NEA portfolio.
物理学（牛顿定律、力矩、能量转换、波）和化学（腐蚀、聚合物结构）的科学原理支撑着工程决策。三角函数可用于分解力。所有这些应用背景构建了书面考试所需的分析思维，以及NEA作品集中所需的技术论证。
