2. Core Engineering Skills and Thinking | 核心工程技能与思维
Engineering thinking is at the heart of the curriculum. Students learn to approach problems systematically using the 'Plan-Do-Review' cycle. This involves defining a design brief, researching existing products, generating multiple ideas, selecting the best concept, making a prototype, testing it, and evaluating outcomes. Iteration is encouraged—failure is seen as a step towards improvement.
工程思维是课程的核心。学生学会使用“计划-执行-回顾”循环系统地处理问题。这包括定义设计任务，研究现有产品，产生多种创意，选择最佳概念，制作原型，进行测试并评估结果。迭代受到鼓励——失败被视为迈向提升的一步。
Practical skills include accurate measuring with rulers and callipers, marking out materials, cutting, joining, and finishing techniques. Students are introduced to basic hand tools such as saws, drills, files, and soldering irons under strict safety supervision. They also learn to read and draw simple engineering diagrams using orthographic projection and isometric sketching.

The concept of load is broken into dead loads (weight of structure) and live loads (people, furniture, wind). Students calculate stress and strain informally, using formulas without complex algebra:
载荷的概念分为静载（结构自重）和活载（人、家具、风）。学生非正式地计算应力和应变，使用不含复杂代数的公式：
Stress = Force ÷ Cross-sectional Area
Triangulation is introduced as a method to make frames rigid. Popsicle-stick bridges are weighted until collapse, and students graph force vs. deflection. They learn to recognise shapes that distribute forces evenly, such as arches and triangles.
引入三角测量作为一种使框架刚性的方法。冰棒棍桥被加重直至坍塌，学生绘制力与挠度的关系图。他们学会识别能均匀分布力的形状，如拱形和三角形。

ents redesign a common product (e.g., a plastic water bottle) to be more sustainable by suggesting material changes, reuse strategies, or alternative supply chains. This fosters systems thinking.
生命周期分析的概念被简化：原材料开采 → 制造 → 使用 → 处置。学生重新设计一种常见产品（如塑料水瓶），通过建议材料变更、重复利用策略或替代供应链使其更具可持续性。这培养了系统思维。
Energy calculations are practical: they measure the electrical energy used by a motor to lift a mass and compare it to the potential energy gained, discovering losses due to friction and heat. Efficiency is introduced as:
能源计算是实际的：他们测量电机提升质量所消耗的电能，并与获得的势能进行比较，发现由于摩擦和热量造成的损失。效率的引入为：
Efficiency (%) = (Useful Output Energy ÷ Total Input Energy) × 100
This module links personal responsibility with global challenges, encouraging students to think as future engineers designing a greener world.
该模块将个人责任与全球挑战联系起来，鼓励学生以未来工程师的身份思考如何设计一个更绿色的世界。
9. Assessment Methods and Evidence of Learning | 评估方法与学习证据
There is no timed written exam for Year 7 CIE Engineering. Instead, assessment is continuous and portfolio-based. Students compile a digital or physical folder containing design journals, photographs of prototypes, test data, and written reflections. Teachers assess against Cambridge's engineering learning objectives: knowledge, application, and practical skills.
Year 7 CIE 工程课程没有定时笔试。评估是持续进行的，以作品集为基础。学生汇编一个数字或物理文件夹，包含设计日志、原型照片、测试数据和书面反思。教师根据剑桥工程学习目标进行评估：知识、应用和实践技能。
Each module has at least one assessed practical task, marked using a rubric that covers design process, making quality, testing, and evaluation. Peer assessment is used to develop communication and critical feedback skills. A final 'Grand Challenge' at the end of the year pulls together multiple modules, such as designing and building a small vehicle that must travel a set distance and stop automatically.
每个模块至少有一个评估的实践任务，使用涵盖设计过程、制作质量、测试和评估的评分标准进行评分。同伴评估用于发展沟通和批判性反馈技能。学年末的“大挑战”综合多个模块，例如设计并建造一辆必须行驶设定距离并自动停止的小车。
Self-reflection is a key component. Students write short statements about what worked, what didn't, and how they would improve their design. This meta-cognitive practice prepares them for the rigorous documentation required in IGCSE Engineering (0486).
自我反思是关键组成部分。学生撰写简短陈述，说明哪些有效、哪些无效以及他们将如何改进设计。这种元认知实践为他们应对IGCSE工程学（0486）所要求的严格文档做准备。
10. Study Tips and Progression Pathways | 学习技巧与进阶路径
To excel in Year 7 Engineering, students should actively engage in class workshops, ask questions, and not be afraid to make mistakes. Keeping an organised logbook is crucial—sketches should be labelled, dates recorded, and test results tabulated. At home, practising drawing in 3D and taking apart old mechanical toys to examine gears and motors can deepen understanding.
要在Year 7工程学中取得优异成绩，学生应积极参与课堂工作坊，提出问题，不要害怕犯错。保持整齐的日志至关重要——草图应标注，记录日期，测试结果应制成表格。在家可以练习3D绘图，拆解旧机械玩具以检查齿轮和马达，从而加深理解。
