📚 IGCSE WJEC Engineering: A Parent’s Guide to Supporting Success | IGCSE WJEC 工程：家长辅导指南

If your child is studying WJEC Engineering, you may wonder how to help when you are not an engineer. The good news is that parents can support revision, organise practical work and practise exam skills without knowing every formula. This guide explains the main areas assessed, simple ways to test knowledge at home, and the best roles for parents in the design-and-make projects.

如果孩子正在学习 WJEC 工程，你可能会担心自己不是工程师，不知道如何提供帮助。好消息是，家长即使不熟悉所有公式，也能支持复习、安排实践任务并练习考试技巧。本指南说明主要考查内容、在家测验知识的简单方法，以及家长在设计与制作项目中最适合扮演的角色。

1. Understand the Qualification Structure | 了解资格证书结构

WJEC Engineering is usually assessed through a written examination and controlled assessment or practical units. The exact weighting can differ between centres, so ask the school for a course outline. The written paper often uses real-world engineering scenarios and requires short answers, calculations and extended responses.

WJEC 工程通常通过笔试和受控评估或实践单元来考核。具体权重可能因学校而异，因此建议向学校索取课程大纲。笔试常以真实工程情境为背景，要求简答题、计算题和扩展回答。

As a parent, your first task is to know which units are being taken in each term. Put deadlines for coursework, practical making and mock exams on a family calendar. This reduces last-minute panic and helps your teenager balance theory and workshop tasks.

作为家长，第一项任务是了解每个学期正在学习哪些单元。把课程作业、实践制作和模拟考试的截止日期写进家庭日历。这样可以减少临时慌乱，帮助孩子平衡理论学习和车间任务。

2. Key Topics Parents Should Recognise | 家长应认识的核心主题

WJEC Engineering covers materials, manufacturing processes, mechanical systems, electrical and electronic control, structures and design communication. Parents do not need to master these topics; they can ask open questions such as ‘Which material did you choose and why?’ or ‘What would happen if the load increased?’

WJEC 工程涵盖材料、制造工艺、机械系统、电气与电子控制、结构以及设计交流。家长不需要精通这些主题，但可以提出开放性问题，例如“你为什么选择这种材料？”或“如果载荷增加会发生什么？”

Use everyday objects as revision prompts. A bicycle frame can start a conversation about aluminium alloys, triangles in structures, and forces; a kettle can lead to electrical safety, thermostats and materials. These small discussions build the technical vocabulary exam markers expect.

用日常物品作为复习提示。自行车的车架可以引出铝合金、结构中的三角形和受力等话题；一个电水壶可以引出电气安全、温控器和材料等知识。这些简短的讨论能积累阅卷老师看重的专业词汇。

3. How WJEC Engineering Uses Maths | WJEC 工程如何考查数学

Mathematical problem-solving is one of the biggest sources of lost marks in engineering exams. Common skills include rearranging equations, converting units, calculating areas and volumes, using ratios for gear trains or pulleys, and calculating stress, strain and mechanical advantage.

数学解题是工程考试中最容易失分的部分之一。常见技能包括公式变形、单位换算、面积和体积计算、用比例计算齿轮系或滑轮，以及计算应力、应变和机械效益。

Useful relationships to practise include:

需要练习的重要关系式包括：

• Stress = Force ÷ Area, often written σ = F ÷ A
• Strain = Change in length ÷ Original length
• Mechanical advantage = Load ÷ Effort
• Ohm’s law: V = I × R
• Density = Mass ÷ Volume

• 应力 = 力 ÷ 面积，常写作 σ = F ÷ A
• 应变 = 长度变化 ÷ 原始长度
• 机械效益 = 负载 ÷ 作用力
• 欧姆定律：V = I × R
• 密度 = 质量 ÷ 体积

At home, ask your child to rearrange a formula aloud before substituting numbers. Many questions first require unit conversion, such as millimetres to metres or milliamps to amps; missing this step can make a correct method give a wrong answer.

在家可以让孩子先口头变形公式，再代入数字。许多题目首先需要单位换算，例如毫米换算为米或毫安换算为安；忽略这一步会让正确的解题方法得到错误答案。

4. Materials and Their Properties | 材料及其性能

WJEC expects students to select materials by considering properties such as strength, hardness, toughness, ductility, conductivity and weight. Parents can help by practising property definitions with flashcards: strength is resistance to force; hardness is resistance to scratching or denting; toughness is ability to absorb impact without fracturing.

WJEC 要求学生根据强度、硬度、韧性、延展性、导电性和重量等性能选择材料。家长可以用闪卡帮助孩子练习这些定义：强度是抵抗外力的能力；硬度是
