1. Introduction to SQA Engineering | SQA 工程课程介绍
The SQA Engineering course is designed to give learners a broad introduction to the principles of engineering science and practice. At Year 9 level, this often aligns with the Broad General Education (BGE) phase or serves as a bridge to National 4/5 Engineering Science. The curriculum emphasises problem-solving, creativity, and the application of mathematics and science in real-world engineering contexts.
SQA 工程课程旨在让学生对工程科学原理及实践有一个广泛的入门认识。在 Year 9 阶段，这通常与广泛通识教育（BGE）阶段相衔接，或作为通往 National 4/5 工程科学的桥梁。课程大纲强调问题解决、创造力，以及数学和科学在真实工程情境中的应用。
2. Course Structure and Levels | 课程结构与等级
In the Scottish education system, Year 9 students are typically in S3, which is part of the BGE phase. However, many schools begin delivering National 5 Engineering Science content in S3 to prepare learners for formal qualifications in S4. The curriculum can be broken down into mandatory units covering both theoretical knowledge and practical application. These units are often assessed through a combination of end-of-topic tests, practical assignments, and a final project.
在苏格兰教育体系中，Year 9 学生通常就读 S3，属于 BGE 阶段。然而，许多学校会在 S3 开始教授 National 5 工程科学的内容，为学生在 S4 参加正式资格评估做准备。该课程可分解为必修单元，涵盖理论知识及实践应用。这些单元通常通过章节测验、实践作业和最终项目的组合方式进行评估。
3. Core Units Overview | 核心单元概览
The core content of SQA Engineering Science is organised around several key areas: Engineering Systems, Mechanical Systems, Electrical and Electronic Systems, and Programmable Control. In addition, learners explore the Engineering Design process, materials, and manufacturing techniques.
