1. What is SQA Higher Engineering Science? | 什么是SQA高级工程科学？
SQA Higher Engineering Science is a one-year course at SCQF Level 6, equivalent in depth to AS-level qualifications. It blends physics, mathematics, and technology to solve real-world engineering problems. Learners analyse electronic circuits, mechanical systems, and control logic while considering social and environmental impacts.
SQA高级工程科学是一门为期一年的SCQF第6级课程，深度相当于AS级别。它融合了物理、数学和技术，以解决现实世界的工程问题。学习者分析电子电路、机械系统和控制逻辑，同时考虑社会与环境影响。
2. The Aims and Skills Developed | 课程目标与技能培养
The course aims to develop the ability to apply engineering science principles, use computer-aided design and simulation tools, construct and test solutions, and communicate ideas effectively. Key transferable skills include analytical thinking, numeracy, problem-solving, and team collaboration.
本课程旨在培养学生应用工程科学原理、使用计算机辅助设计和仿真工具、构建和测试方案以及有效交流思想的能力。关键的通用技能包括分析思维、计算能力、问题解决和团队协作。
3. Course Structure and Recommended Hours | 课程结构与建议学时
The Higher Engineering Science course requires approximately 120 hours of study. It consists of three mandatory units: Engineering Contexts and Challenges (20 hours), Electronics and Control (50 hours), and Mechanisms and Structures (50 hours). An additional 8 hours of assessment time is set aside for the practical assignment.
高级工程科学课程要求约120小时的学习时间。它包含三个必修单元：工程背景与挑战（20小时）、电子与控制（50小时）和机械与结构（50小时）。另有8小时的评估时间用于实践作业。
4. Unit 1: Engineering Contexts and Challenges | 单元1：工程背景与挑战
This introductory unit examines the role of engineering in society. Key topics include systems thinking (input-process-output), energy sources and efficiency, life-cycle analysis of products, and the professional responsibilities of engineers. Learners explore case studies on renewable energy, smart cities, and sustainable design.
本导论单元探讨工程在社会中的作用。关键主题包括系统思维（输入-处理-输出）、能源和效率、产品生命周期分析以及工程师的职业责任。学习者研究可再生能源、智慧城市和可持续设计的案例。
5. Unit 2: Electronics and Control | 单元2：电子与控制
Electronics and Control constitutes the largest unit. Students design, simulate, and build digital and analogue circuits. Core topics include combinational logic using gate symbols, Boolean algebra simplification, sequential logic elements (D-type flip-flops, ripple counters), and the use of 555 timers. A significant portion is dedicated to embedded control: microcontrollers (e.g., PICAXE or Arduino) are programmed to read analogue inputs from LDRs or thermistors, make decisions, and control outputs such as LEDs, motors, and seven-segment displays. Circuit simulation software like Yenka or Circuit Wizard is frequently used.
电子与控制是最大的单元。学生设计、仿真和构建数字与模拟电路。核心主题包括使用逻辑门符号的组合逻辑、布尔代数简化、时序逻辑元件（D型触发器、纹波计数器）以及555定时器的使用。很大一部分内容侧重于嵌入式控制：对微控制器（如PICAXE或Arduino）进行编程，以读取来自光敏电阻或热敏电阻的模拟输入，做出决策，并控制输出设备，如LED、电机和七段数码管。经常使用Yenka或Circuit Wizard等电路仿真软件。
Important calculations and concepts include:
重要的计算与概念包括：
- Voltage divider rule for sensor interfacing
- Ohm’s law (V = IR) applied to circuit analysis
- RC timing for monostable and astable configurations
- Boolean expression simplification and truth table construction
- Flowchart-based programming and input/output subroutines
- 传感器接口的分压器规则
- 应用于电路分析的欧姆定律（V = IR）
- 单稳态与非稳态配置的RC定时计算
- 布尔表达式简化与真值表构建
- 基于流程图的编程与输入/输出子程序
Vout = Vin × (R₂ / (R₁ + R₂))
T = 1.1 × R × C (monostable)
f = 1.44 / ((R₁ + 2×R₂) × C) (astable)
6. Unit 3: Mechanisms and Structures | 单元3：机械与结构
This unit explores mechanical engineering fundamentals. Topics include analysis of forces in static equilibrium, bending moments in beams, and simple frame structures. Students calculate stress, strain, Young’s modulus, and use these to assess material suitability. Gear systems, pulleys, and linkages are studied in terms of velocity ratios, mechanical advantage, and efficiency. Energy transfers and the conservation of energy principle underpin many design tasks.
本单元探讨机械工程基础。主题包括静态平衡中的力分析、梁的弯矩和简单框架结构。学生计算应力、应变和杨氏模量，并据此评估材料的适用性。研究齿轮系统、滑轮和连杆机构的速度比、机械效益和效率。能量转换和能量守恒原理是许多设计任务的基础。
σ = F / A (stress)
ε = ΔL / L₀ (strain)
E = σ / ε (Young’s modulus)
Velocity ratio = N₂ / N₁ (gear teeth ratio)
7. Assessment: Question Paper and Assignment | 评估：考试与作业
The course is assessed through two components. The question paper, worth 110 marks (65%), lasts 2 hours 30 minutes. It tests knowledge from all three units in multiple-choice and structured extended-response formats. The assignment contributes 60 marks (35%) and is conducted over 8 hours under supervised conditions. Candidates identify an engineering problem, research a solution, construct and test a prototype (physical or simulated), and produce a detailed report. Both components are externally marked by SQA.
该课程通过两个组成部分进行评估。笔试占110分（65%），时长为2小时30分钟，以选择题和结构化论述题形式
