The circular economy, waste hierarchy (reduce, reuse, recycle), and relevant ISO standards are taught to promote ethical engineering.
可持续性和环境责任同样会被考查。学生应讨论产品的生命周期，包括原材料开采、制造中的能源消耗以及报废处置或回收。教授循环经济、废弃物层级（减量、复用、回收）以及相关 ISO 标准，以倡导符合道德的工程实践。
12. Assessment, Exam Tips and Revision | 评估、考试技巧与复习
To excel in the Unit 1 examination, time management and structured answers are critical. Read all command words carefully – "explain" requires a justification, while "calculate" demands a numerical answer with working. The extended-response question at the end of the paper often integrates multiple topics; practising these under timed conditions builds confidence.
要在单元一考试中取得优异成绩，时间管理和结构化的答题至关重要。仔细阅读所有指令词——“解释”需要陈述理由，而“计算”则要求给出带有运算过程的数值答案。试卷末尾的扩展性问题通常会整合多个主题；在限时条件下练习这类题目可以增强信心。
For Unit 2, maintaining a logbook and regularly updating design iterations is crucial. Photographic evidence of prototypes, annotated circuit diagrams, and user feedback forms all contribute to a high-scoring portfolio. Start early and set internal deadlines to avoid last-minute rushes.
对于单元二，保持日志并定期更新设计迭代至关重要。原型的照片证据、带注释的电路图和用户反馈表都有助于获得高分作品集。尽早开始并设定内部截止日期，以避免最后赶工。
Revision should focus on interleaving theory with practical examples. Use past papers from the WJEC website, create mind maps linking materials to manufacturing processes, and form study groups to discuss design solutions. Remember that the specification is your roadmap – every topic listed is assessable.
复习应注重将理论与实际示例交错结合。使用 WJEC 网站上的历年真题，创建将材料与制造工艺联系在一起的思维导图，并组建学习小组讨论设计方案。请记住，课程大纲就是你的路线图——列出的每个主题都可能被评估。
