5. Strengthening of Mathematical Requirements | 数学能力要求的加强
The mathematical demand has been raised to ensure readiness for A-level and higher education. Key formulas are now provided in a booklet, but students must choose the correct equation and rearrange it accurately. Familiarity with exponential decay, simultaneous equations, and trigonometric graphs is essential.
数学要求已提高，以确保为 A-level 和高等教育做好准备。关键公式现在以公式手册形式提供，但学生必须选择正确的方程并准确地进行移项。熟悉指数衰减、联立方程和三角函数图是必不可少的。
Calculus concepts are introduced in a limited way. For instance, learners may need to understand that velocity is the derivative of displacement or that work done equals the area under a force-displacement graph. Simple integration and differentiation are not assessed, but interpreting gradients of curves is required.
微积分概念以有限方式引入。例如，学习者可能需要理解速度是位移的导数，或功等于力-位移图下的面积。不评估简单的积分和微分，但要求解释曲线的斜率。
The following equations appear frequently and must be used in applied contexts:
以下方程经常出现，必须能在实际情境中运用：
σ = E × ε
F = m × a
P = F / A
Problems will combine mathematical skills with data interpretation, such as calculating a component’s factor of safety from given ultimate tensile stress and working stress values.
问题将把数学技能与数据解释结合起来，例如根据给定的极限拉伸应力和工作应力值计算构件的安全系数。
6. Introduction of New Topics in Mechanics | 力学中新主题的引入

尽管实践评估主要通过 NEA 进行，但笔试试卷现在包含一个专门部分，用于解读车间程序和测量。题目可能呈现游标卡尺或千分尺读数的照片，要求准确判读。
Candidates could be asked to identify a manufacturing process from a set of surface finish images or to suggest an appropriate non-destructive testing (NDT) method for a welded joint. Understanding of dye penetrant, ultrasonic and radiography testing basics is thus needed.
考生可能被要求根据表面光洁度图像识别制造工艺，或为焊接接头建议合适的无损检测（NDT）方法。因此，需要了解着色渗透、超声波检测和射线照相检测的基础知识。
Safety symbols and risk assessment skills feature in short-answer questions. This change ensures that even the written examination rewards shop-floor awareness equally alongside theoretical knowledge.
安全标志和风险评估技能会出现在简答题中。这一改变确保即使笔试也能同等地奖励车间意识与理论知识。
9. Changes to Marking and Grade Boundaries | 评分和等级界限的变化
With the revised specification come new marking guidelines. Examiners will apply a ‘best fit’ approach within levels of response for extended answers, but key indicative content must be present for top marks. Vague statements will not earn high marks.
随着大纲的修订，新的评分指南也已出台。考官将在扩展答案的等级评分内采用“最佳匹配”方法，但要拿到高分，必须包含关键的指示性内容。模糊的陈述将无法获得高分。
Grade boundaries are expected to be slightly higher in the first session because of the enhanced focus on clarity of communication and quality of written expression. AQA has released example boundaries based on mock trials:
由于更强调沟通清晰度和书面表达质量，预计首次考试的等级界限会略高。AQA 已根据模拟试验发布了示例界限：
| Grade | 等级 | Typical Mark (out of 160) | 典型分数（满分 160） |
|---|---|
| A | 128 |
| B | 110 |
| C | 92 |
| D | 74 |
| E | 56 |
These boundaries are indicative; final thresholds will depend on student performance. Consistency with other reformed qualifications means an A grade may require around 80% of the total marks.
这些界限是参考性的；最终阈值将取决于学生表现。与其他改革后的资格保持一致，意味着获得 A 等级可能需要总分的 80% 左右。
10. Resource and Textbook Updates | 资源和教材的更新
AQA has endorsed new textbooks specifically aligned with the 2026 specification. These books include dedicated mathematical skills sections, expanded sustainability case studies, and online simulation access codes. Teachers are encouraged to replace older editions.

示例 NEA 作品集和简短视频教程已在 AQA 网站发布，展示了设计日志和制造作品的预期标准。真题试卷将从 2026 年开始提供，第一套样卷已于 2025 年春季发布。
Digital resources such as interactive stress-strain graphing tools and PLC simulation sandboxes are recommended for classroom use. Schools should invest in these to give students hands-on experience without expensive hardware.
推荐在课堂上使用诸如交互式应力-应变绘图工具和 PLC 仿真沙盒等数字资源。学校应投入这些资源，让学生无需昂贵硬件即可获得动手经验。
11. Impact on Teaching and Learning | 对教学和学习的影响
The changes require a shift towards project-based learning. Theory lessons must be integrated with practical investigations. For instance, teaching moments of inertia can be combined with a simple experiment measuring oscillation of a compound pendulum.
这些变化要求转向基于项目的学习。理论课必须与实践调查相结合。例如，教授转动惯量时，可以结合测量复摆振荡的简单实验。
Teachers need to allocate dedicated time for iterative NEA progress checking, as the digital log demands continuous evidence collection. This may mean restructuring scheme of work to allow six to eight monitored sessions across the academic year.
教师需要分配专门时间用于 NEA 迭代进度检查，因为数字日志要求持续收集证据。这可能意味着要重组教学计划，以在一个学年中安排六到八次受监控的实践环节。
Collaboration between the engineering department and mathematics department becomes crucial, given the explicit mathematical requirements. Joint planning sessions can help ensure that students possess the necessary numerical skills before they encounter them in an engineering context.
鉴于明确的数学要求，工程系与数学系之间的协作变得至关重要。联合备课会议有助于确保学生在工程情境中遇到这些内容之前，就已经具备必要的计算技能。
12. Looking Ahead: Future Trends in Engineering Education | 展望未来：工程教育的趋势
Beyond 2026, the AQA engineering specification is likely to incorporate artificial intelligence (AI) awareness, such as machine learning in quality control, as industry adoption accelerates. While not yet assessed, teachers are advised to familiarise students with basic AI concepts through enrichment activities.
2026 年之后，随着行业采用加速，AQA 工程大纲很可能会纳入人工智能（AI）意识，例如质量控制中的机器学习。虽然现时未作考核，但建议教师通过拓展活动，让学生熟悉基本的 AI 概念。
Remote monitoring and Internet of Things (IoT) integrations are emerging as essential trends. Future specifications might require students to design systems that transmit sensor data to cloud platforms for predictive maintenance analysis.
远程监控和物联网（IoT）集成正在成为重要趋势。未来大纲可能会要求学生设计能将传感器数据传输到云平台、用于预测性维护分析的系统。
Cross-disciplinary skills combining engineering with environmental science, ethics and global economics will gradually shape assessment tasks. Students who can articulate social impact alongside technical solutions will be best prepared for the changing landscape.
