6. Course Assessment and the Assignment | 课程评估与课程作业
National 5 Computing Science is assessed through two components: a question paper and a practical assignment. The question paper tests knowledge and understanding across all four units, divided into short answer and extended response questions. It lasts 2 hours and contributes 110 marks (scaled to 80% of the final grade). Questions often require reading code, interpreting SQL, analysing a website snippet, or evaluating a system. Year 9 students can start familiarising themselves with the type of questions by attempting practice exercises early.
National 5 计算机科学的评估由两部分组成：一份试卷和一份实践课程作业。试卷考查所有四个单元的知识与理解，分为简答题和拓展问答题。考试持续 2 小时，110 分制（折算后占最终成绩的 80%）。问题常要求阅读代码、解读 SQL、分析网站片段或评价一个系统。九年级学生可以通过尽早尝试练习来熟悉题型。
The assignment is a practical task set by SQA, lasting 8 hours under supervised conditions. It accounts for 50 marks (scaled to 20% of the grade). Candidates must solve a problem by integrating skills from multiple units, such as designing a database, writing SQL queries, and creating a web interface. The assignment assesses planning, implementation, testing, and evaluation. In Year 9, teachers often build towards this by giving small-scale integrated projects that mirror the assignment style.
课程作业是由 SQA 设定的实践任务，在监督条件下持续 8 小时。满分 50 分（折算后占成绩的 20%）。考生必须通过整合多个单元的技能来解决一个问题，例如设计数据库、编写 SQL 查询和创建网页界面。作业评估计划、实施、测试和评价。在九年级，教师通常通过给出模拟作业风格的小型综合项目来为此做准备。
7. Developing Computational Thinking Skills | 培养计算思维技能
Computational thinking is the backbone of the entire course, not just programming. It involves decomposition (breaking problems into smaller parts), pattern recognition, abstraction (focusing on important information), and algorithm design. Year 9 students practise these techniques in every unit – for example, normalising a database involves abstraction, debugging requires pattern recognition, and planning a website uses decomposition. Explicitly teaching these skills helps learners think like computer scientists.
计算思维是整个课程的支柱，而不仅仅是编程。它包括分解（将问题拆分为更小的部分）、模式识别、抽象（关注重要信息）以及算法设计。九年级学生在每个单元中都会练习这些技术——例如，规范化数据库涉及抽象，调试需要模式识别，规划网站则使用分解。明确教授这些技能有助于学习者像计算机科学家一样思考。
Unplugged activities, such as card sorting or writing algorithms for everyday tasks, can strengthen computational thinking without a computer. They also promote collaborative learning and problem-solving. As students progress, they learn to recognise which thinking strategy to apply and how to communicate their reasoning effectively. This meta-cognitive layer becomes valuable when tackling the open-ended problems found in the assignment and exams.
不插电活动，如卡片分类或为日常任务编写算法，可以在没有计算机的情况下强化计算思维。它们还能促进协作学习和问题解决。随着学生的进步，他们学会识别该应用哪种思维策略，以及如何有效传达自己的推理。这种元认知层面在应对课程作业和考试中的开放性问题时变得很有价值。
8. Progression Pathways After Year 9 | 九年级之后的进阶路径
Completing a Year 9 computing course grounded in National 5 concepts opens several doors. The most direct route is National 5 Computing Science in S4, which leads to Higher Computing Science in S5/S6. From there, students can pursue Advanced Higher or move into vocational qualifications, such as a National Progression Award in Software Development, Cyber Security, or Digital Media.
