1. Course Overview and Code | 课程概览与代码
OCR’s GCSE (9–1) in Engineering has the qualification code J310. It is designed to inspire and equip students with real-world engineering skills. The course is structured around three key components: R101 – Engineering Principles, R102 – Engineering Design and Manufacture, and R103 – Practical Engineering. Together, these build a strong foundation in both theoretical knowledge and hands-on application, aligning with modern engineering industries.
OCR 的 GCSE（9–1）工程课程代码为 J310。它旨在激发并培养学生的实际工程技能。课程围绕三个关键部分构建：R101 – 工程原理，R102 – 工程设计与制造，以及 R103 – 实践工程。这些部分共同为理论知识和实践应用奠定了坚实基础，与现代工程行业紧密接轨。
The course encourages students to analyse engineered products, understand manufacturing processes, and develop practical workshop skills. It is assessed through two written exams and a non-examined assessment (NEA). The linear structure means all exams are taken at the end of the course, with the NEA completed under controlled conditions during the learning period.
该课程鼓励学生分析工程产品、理解制造流程并培养实际车间技能。评估方式包括两场笔试和一项非考试评估（NEA）。线性结构意味着所有考试在课程结束时进行，NEA 则在教学期间于受控条件下完成。
2. Assessment Objectives (AOs) | 评估目标
The OCR Engineering specification defines four Assessment Objectives that shape every exam question and the NEA marking criteria. AO1 focuses on demonstrating knowledge and understanding of engineering principles, materials, and processes. AO2 is about applying this knowledge and understanding in unfamiliar contexts. AO3 requires analysis and evaluation of information, while AO4 involves demonstrating and applying practical skills and processes.
OCR 工程大纲定义了四个评估目标，这些目标决定了每道试题和 NEA 评分标准的走向。AO1 侧重于展示对工程原理、材料和流程的知识与理解。AO2 则要求在不熟悉的语境中应用这些知识与理解。AO3 要求对信息进行分析与评估，而 AO4 则涉及展示并应用实践技能与流程。
Weightings are distributed as follows: AO1 – 30%, AO2 – 30%, AO3 – 20%, AO4 – 20%. This balance rewards students who not only recall facts but also think critically, solve problems, and handle tools and materials competently. Nearly half the marks come from higher-order skills (AO2 and AO3), meaning practice in applying concepts is essential.
各目标权重分配如下：AO1 – 30%，AO2 – 30%，AO3 – 20%，AO4 – 20%。这种平衡不仅奖励那些能记忆事实的学生，也奖励那些能批判性思考、解决问题并熟练操作工具与材料的学生。接近一半的分数来自高阶技能（AO2 和 AO3），因此练习应用概念至关重要。
3. Exam Structure and Weighting | 考试结构与分值
Two written papers account for 70% of the final grade. Paper R101 (Engineering Principles) lasts 1 hour 30 minutes and carries 80 marks (40% of the GCSE). It covers core engineering science, mathematics, materials, manufacturing processes, and systems. Question types include multiple-choice, short-response, and extended-response tasks. A scientific calculator is required.
