1. A New Specification for 2026 | 2026 年全新课程大纲
Pearson Edexcel is updating the AS Engineering specification (8ET0) to align with the latest industry standards and university entrance requirements. The 2026 specification will replace the 2017 version, and first teaching is expected from September 2025. While core principles of mechanical, electrical, and structural engineering remain, the content has been streamlined to reduce repetition and to introduce emerging topics.
培生爱德思正在更新 AS 工程课程大纲（8ET0），以符合最新行业标准和大学入学要求。2026 年大纲将取代 2017 年版本，预计首次教学从 2025 年 9 月开始。虽然机械、电气和结构工程的核心原理保持不变，但内容已被精简，以减少重复并引入新兴主题。
Key content areas retained include statics, dynamics, materials, digital electronics, and manufacturing processes. New elements, however, cover smart materials, energy storage systems, and basic programming logic for microcontrollers. These changes reflect the growing role of automation and clean energy in engineering careers.
保留的关键内容领域包括静力学、动力学、材料、数字电子学和制造工艺。然而，新元素涵盖了智能材料、储能系统以及微控制器的基本编程逻辑。这些变化反映了自动化和清洁能源在工程职业中日益重要的作用。
2. Revised Assessment Objectives | 修订后的评估目标
The Assessment Objectives (AOs) have been reweighted for 2026. AO1 (knowledge and understanding) will now account for 30% of the total marks, AO2 (application of knowledge) for 40%, and AO3 (analysis and evaluation) for 30%. This shift places greater weight on applying theory to unfamiliar contexts and critically evaluating designs or processes.
评估目标（AOs）在 2026 年重新调整了权重。AO1（知识与理解）现在占总分的 30%，AO2（知识应用）占 40%，AO3（分析与评估）占 30%。这一转变更加重视将理论应用于陌生情境，以及批判性地评估设计或工艺。
In practice, you will see fewer straightforward definition questions and more scenario‑based problems. For example, instead of simply stating the formula for stress, you might be asked to calculate the factor of safety for a given structure and then suggest two modifications to improve it, justifying your choices.
在实践中，你会看到更少的直接定义题，更多的基于场景的问题。例如，你或许不会被要求仅仅陈述应力公式，而是可能被要求计算给定结构的安全系数，然后提出两种改进方案并说明理由。
3. Unit 1: Engineering Principles – Updated Core Content | 单元一：工程原理 – 更新的核心内容
Unit 1 (written exam, 2 hours) now includes a dedicated section on ‘Engineering for a Sustainable Future’. This covers life‑cycle analysis, renewable energy systems, and the environmental impact of material selection. You must be able to interpret carbon footprint data and apply the circular economy model to product design.
单元一（笔试，2 小时）现在包含一个专门的部分“面向可持续未来的工程”。这涵盖了生命周期分析、可再生能源系统以及材料选择对环境的影响。你必须能够解读碳足迹数据，并将循环经济模型应用于产品设计。
The mathematics requirement has also intensified. You are expected to manipulate equations involving logarithms, exponentials, and trigonometry with confidence. The formula sheet has been revised; some constants, such as Young’s modulus for common materials, are now provided, but you must know when and how to apply them.
数学要求也加强了。你需要自信地处理包含对数、指数和三角函数的方程。公式表已经修订；一些常数，如常见材料的杨氏模量，现已给出，但你必须知道何时以及如何应用它们。
4. Unit 2: Engineering Practice – Emphasis on Digital Prototyping | 单元二：工程实践 – 强调数字原型制作
Unit 2 (practical portfolio, internally assessed) moves away from purely hands‑on workshop tasks toward a hybrid model integrating CAD (Computer‑Aided Design), CAM (Computer‑Aided Manufacturing), and basic coding. By 2026, you will need to demonstrate competence in generating 3D models, running simulations, and exporting files for 3D printing or CNC machining.
单元二（实践作品集，内部评估）从纯粹的动手车间任务转向整合 CAD（计算机辅助设计）、CAM（计算机辅助制造）和基础编程的混合模式。到 2026 年，你需要展示生成三维模型、运行模拟以及导出文件用于 3D 打印或 CNC 加工的能力。
The portfolio must now include evidence of an iterative design process. This means showing how you have tested an initial prototype, analysed its performance using sensor data, and refined the design at least twice. The use of Arduino or similar microcontrollers to gather real‑time data (e.g. temperature, force, displacement) is strongly encouraged.
作品集现在必须包含迭代设计过程的证据。这意味着展示你如何测试初始原型、使用传感器数据分析其性能，并对设计进行了至少两次改进。强烈鼓励使用 Arduino 或类似微控制器收集实时数据（如温度、力、位移）。
5. Strengthened Mathematical Demands | 增强的数学要求
Mathematics has always been central to engineering, but the 2026 exams raise the bar. You must be fluent in rearranging compound equations, calculating gradients of non‑linear graphs, and estimating errors. In Unit 1, around 25% of marks will directly target mathematical precision.
数学一直是工程的核心，但 2026 年考试提高了标准。你必须熟练掌握复合方程变形、非线性图形斜率计算以及误差估计。在单元一中，约 25% 的分数将直接针对数学精确度。
Key equations you will use frequently include:
σ = F / A
ε = ΔL / L₀
E = σ / ε
P = VI
V = IR
KE = ½mv²
你将经常使用的关键方程包括：
σ = F / A
ε = ΔL / L₀
E = σ / ε
P = VI
V = IR
KE = ½mv²
Additionally, you should practise using trigonometric ratios for resolving forces, and converting between vector and scalar quantities seamlessly. A solid grasp of units – converting mm² to m², or kN to N – is no longer just desirable; it is essential for avoiding costly mistakes.
此外，你应该练习使用三角比解析力，并流畅地在矢量和标量之间转换。对单位——将 mm² 转换为 m²，或将 kN 转换为 N——的扎实掌握不再只是锦上添花；它对避免代价高昂的错误至关重要。
6. Sustainable Engineering and Green Skills | 可持续工程与绿色技能
Sustainability is not a bolt‑on topic; it is embedded throughout the 2026 specification. In the written exam, you may find questions comparing the embodied energy of steel versus engineered timber, or calculating the efficiency of a wind turbine given power curves. You must be able to discuss the social, economic, and environmental pillars of sustainability.
可持续发展不是一个附加主题；它贯穿于 2026 年大纲之中。在笔试中，你可能会遇到比较钢材与工程木材隐含能量的问题，或者根据功率曲线计算风力涡轮机的效率。你必须能够讨论可持续发展的社会、经济和环境三大支柱。
You will also learn to use the ‘6Rs’ of sustainability (Reduce, Reuse, Recycle, Rethink, Refuse, Repair) in design proposals. For the portfolio, a clear justification of material choice based on life‑cycle impact will earn higher marks than merely selecting the cheapest or strongest option.
你还将学习在设计方案中运用可持续发展的“6R”原则（减少、再利用、再循环、再思考、拒绝、修复）。对于作品集，基于生命周期影响对材料选择做出清晰论证，将比仅仅选择最便宜或最坚固的选项获得更高分数。
7. Digital Engineering and Industry 4.0 | 数字工程与工业 4.0
The integration of digital tools reflects Industry 4.0. In 2026, the specification explicitly mentions ‘digital twin’ concepts, IoT (Internet of Things) sensors, and data analytics. While you are not expected to build a full digital twin, you should understand how real‑time monitoring can optimise maintenance schedules.
数字工具的整合反映了工业 4.0。在 2026 年，大纲明确提到了“数字孪生”概念、物联网传感器和数据分析。虽然你不被要求构建完整的数字孪生体，但你应理解实时监控如何优化维护计划。
In Unit 2, you could use a simple temperature sensor connected to a microcontroller to log data during a structural test. Analysing this data to suggest improvements demonstrates high‑level AO3 evaluation. Familiarity with basic Excel functions, such as trendlines and standard deviation, will be an asset.
在单元二中，你可以使用连接到微控制器的简单温度传感器在结构测试期间记录数据。分析这些数据并提出改进建议，展示了高层次的 AO3 评估能力。熟悉基本的 Excel 函数，如趋势线和标准偏差，将是一大优势。
8. Project‑Based Learning and the NEA | 基于项目的学习与非考试评估
The Non‑Exam Assessment (NEA) component retains its 50% weighting, but the marking criteria have been tightened. The 2026 grid demands stronger evidence of independent research, referencing credible sources, and clear links between testing and modelling. Generic ‘trial and error’ logs will no longer meet the standard.
非考试评估（NEA）部分保持其 50% 的权重，但评分标准已收紧。2026 年的评分网格要求更独立的调研证据、引用可靠来源，以及测试与建模之间的清晰联系。泛泛的“试错”记录将不再符合标准。
You will need to produce a project that addresses a genuine need, with a specification that includes measurable pass/fail criteria. For example, a device that automatically opens a greenhouse vent when the internal temperature exceeds 28 °C would be suitable. The report should document circuit diagrams, CAD drawings, test results, and user feedback.
你需要制作一个解决真正需求的项目，其技术规格应包括可度量的通过/失败标准。例如，一个当内部温度超过 28 °C 时自动打开温室通风口的装置就很适合。报告应记录电路图、CAD 图纸、测试结果和用户反馈。
9. Exam Timing and Weighting Adjustments | 考试时间与权重调整
The overall structure remains two units: one external exam and one coursework portfolio. However, the Unit 1 exam time has been extended from 1 hour 45 minutes to 2 hours, allowing for more complex analysis questions. The mark allocation for Unit 1 is now 80 marks (previously 60), while Unit 2 remains at 60 marks internally assessed.
总体结构仍为两个单元：一次外部考试和一份课程作业作品集。然而，单元一考试时间已从 1 小时 45 分钟延长至 2 小时，以便容纳更复杂的分析题。单元一的分数分配现在为 80 分（此前为 60 分），而单元二保持 60 分内部评估。
This increased weighting of the examined unit (57% vs 43% NEA) means your exam technique becomes even more critical. Time management under pressure, precise command‑word responses, and structured calculations are non‑negotiable skills for securing a top grade.
考试单元权重的增加（57% 对比 43% NEA）意味着你的考试技巧变得更加关键。在压力下的时间管理、精确响应指令词以及结构化的计算，是获得最高等级的必备技能。
10. Resources and Support from Edexcel | 爱德思提供的资源与支持
Pearson is rolling out new textbooks, online revision guides, and active‑learning packages specifically for the 2026 specification. A free ‘transition guide’ will be published in early 2025, highlighting the differences between the 2017 and 2026 specs. Exam‑style practice papers with mark schemes will be available on the official website.
培生正在推出专门针对 2026 年大纲的新教材、在线复习指南和主动学习包。一份免费的“过渡指南”将于 2025 年初发布，重点说明 2017 年和 2026 年大纲之间的差异。官网将提供带评分方案的考试风格练习卷。
Additionally, Exam Wizard is being updated to help you generate customised topic tests. Your teachers will also have access to standardisation materials and training events from autumn 2025. Make sure you use the official specification document, not outdated textbooks, to guide your revision.
此外，Exam Wizard 正在更新，以帮助你生成定制的主题测试。你的老师也将从 2025 年秋季起获得标准化材料和培训活动的权限。务必使用官方大纲文件而非过时的教材来指导你的复习。
11. Trends in Student Performance and Grade Boundaries | 学生表现趋势与等级分数线
Data from the last three exam series shows that students often lose marks on mathematical conversions and on AO3 evaluation chains. Grade boundaries for an A grade have typically been around 62‑65% for Unit 1 and 68‑72% for Unit 2. With the 2026 changes, the higher AO3 weighting may push raw mark thresholds slightly lower initially, but exam boards will maintain comparable outcomes.
过去三个考试系列的数据显示，学生经常在数学换算和 AO3 评估链上失分。A 等级的分数线通常在单元一为 62‑65%，单元二为 68‑72%。随着 2026 年的变化，更高的 AO3 权重最初可能会使原始分数门槛略微降低，但考试局将保持可比的结果。
To stay ahead, practise answering ‘suggest and justify’ style questions, and never leave a quantitative answer without a unit. Use the command words glossary: ‘calculate’ means show all working; ‘explain’ means give reasons; ‘evaluate’ means weigh up pros and cons and make a judgement.
为了保持领先，练习回答“建议并说明理由”类问题，永远不要给出一个没有单位的定量答案。使用指令词表：“calculate”表示显示所有步骤；“explain”表示给出原因；“evaluate”表示权衡利弊并做出判断。
12. Preparing for Success in 2026 | 为 2026 年的成功做准备
Start by mapping your current knowledge against the new specification content and identifying gaps, particularly in sustainability and digital tools. Build a practical project early, documenting every iteration. Use past papers but adapt them: add a layer of environmental analysis to a typical beams question, or incorporate sensor data into a microcontroller prompt.
首先，将你当前的知识与新大纲内容进行对照，找出差距，尤其是在可持续发展与数字工具方面。尽早构建一个实践项目，记录每一次迭代。使用历年真题，但加以改编：在典型的梁问题中加入一层环境分析，或将传感器数据纳入微控制器提示。
Form a study group to discuss ethical engineering dilemmas and share CAD files for peer review. Regularly time yourself on full 2‑hour papers under exam conditions. Finally, remember that the 2026 changes are not meant to trick you; they are designed to make you a more competent, industry‑ready engineer. Embrace the challenge, and you will thrive.
组建学习小组，讨论工程伦理困境，并分享 CAD 文件进行同行评审。定期在考试条件下给自己计时完成完整的 2 小时试卷。最后，记住 2026 年的变化不是要为难你；它们旨在使你成为更有能力、更适合行业需求的工程师。迎接挑战，你将取得成功。
