1. What is Computer Science? | 什么是计算机科学？
Computer Science is not just about using computers – it is the study of how computers work, how they process information, and how we can instruct them to solve problems. In Year 7, you will explore three main areas: Computer Systems (hardware, software, networks), Digital Literacy (staying safe and responsible online), and Computational Thinking (logical reasoning, algorithms, and coding). WJEC focuses on building a solid foundation so that every learner can think like a computer scientist.
计算机科学不仅仅是使用电脑——它研究计算机如何工作、如何处理信息，以及我们如何指示它们解决问题。在 Year 7，你将探索三大领域：计算机系统（硬件、软件、网络）、数字素养（安全负责地上网）和计算思维（逻辑推理、算法与编程）。WJEC 侧重打下扎实基础，让每位学习者都能像计算机科学家一样思考。
2. Computer Systems: Hardware and Software | 计算机系统：硬件与软件
A computer system is made up of hardware (the physical parts you can touch) and software (the programs and instructions that tell the hardware what to do). Key hardware components include the central processing unit (CPU), memory (RAM and ROM), and storage devices. Software is divided into system software – like the operating system, which manages resources – and application software, such as word processors and web browsers. Understanding this distinction helps you appreciate how a machine turns your clicks into actions.
计算机系统由硬件（你可以触摸到的物理部件）和软件（告诉硬件做什么的程序和指令）组成。关键的硬件部分包括中央处理器 (CPU)、内存（RAM 和 ROM）以及存储设备。软件分为系统软件（例如管理资源的操作系统）和应用软件（如文字处理器和网页浏览器）。理解这种区别能让你领略机器如何将你的点击转化为实际动作。
3. Input, Output and Storage Devices | 输入、输出与存储设备
Devices connected to a computer are categorised as input, output or storage. Input devices send data into the computer (e.g. keyboard, mouse, microphone, touchscreen). Output devices display or present the results (e.g. monitor, speakers, printer). Storage devices hold data permanently or temporarily (e.g. hard disk drive, USB flash drive, cloud storage). The following table gives common examples with their bilingual terms.
连接到计算机的设备可分为输入设备、输出设备和存储设备。输入设备将数据送入计算机（例如键盘、鼠标、麦克风、触摸屏）。输出设备显示或呈现结果（例如显示器、扬声器、打印机）。存储设备永久或暂时保存数据（例如硬盘驱动器、U盘、云存储）。下表列出了常见例子及其双语名称。
| Input Devices | 输入设备 | Output Devices | 输出设备 | Storage Devices | 存储设备 |
| Keyboard | 键盘 | Monitor | 显示器 | Hard Disk Drive (HDD) | 硬盘驱动器 |
| Mouse | 鼠标 | Printer | 打印机 | USB Flash Drive | U盘 |
| Microphone | 麦克风 | Speakers | 扬声器 | Cloud Storage | 云存储 |
4. How Computers Communicate: Networks and the Internet | 计算机如何通信：网络与互联网
A network is formed when two or more computers are connected to share resources and data. The internet is a global network of networks, connecting billions of devices worldwide. In Year 7, you learn the difference between a Local Area Network (LAN), which covers a small area like a school, and a Wide Area Network (WAN), which spans large geographical distances. Simple network hardware such as routers, switches, and wireless access points are also introduced. Understanding how a message travels from your device to a friend's across the world makes networking exciting.
当两台或更多计算机连接起来共享资源和数据时，就形成了网络。互联网是全球范围的网络之网络，连接着数十亿台设备。在 Year 7，你将学习局域网 (LAN) 和广域网 (WAN) 的区别：LAN 覆盖像学校这样的小区域，而 WAN 跨越广阔的地理距离。还会介绍路由器、交换机和无线接入点等简单的网络硬件。理解一条信息如何从你的设备传递到世界另一端朋友那里，使网络知识变得生动有趣。
5. Staying Safe Online: E-Safety | 安全上网：网络安全
Being a responsible digital citizen is a core part of the WJEC syllabus. Topics include creating strong passwords, recognising phishing emails, protecting personal information, and understanding the consequences of cyberbullying. Students learn the importance of not sharing private details publicly and how to report inappropriate content. Schools often use the 'SMART' rules: Safe, Meeting, Accepting, Reliable, Tell. By building these habits early, learners can confidently enjoy the benefits of the internet while minimising risks.
做负责任的数字公民是 WJEC 大纲的核心部分。主题包括创建强密码、识别钓鱼邮件、保护个人信息以及理解网络欺凌的后果。学生将学到不在公开场合分享私人细节的重要性，以及如何举报不当内容。学校常使用“SMART”规则：安全、会面、接受、可靠、告知。尽早养成这些习惯，学习者就能自信地享受互联网的好处，同时将风险降到最低。
6. Computational Thinking: Breaking Down Problems | 计算思维：分解问题
Computational thinking is a problem-solving approach that involves four key techniques: decomposition (breaking a problem into smaller parts), pattern recognition (spotting similarities), abstraction (focusing on essential details while ignoring irrelevant information), and algorithm design (creating step-by-step solutions). For example, when planning a school trip, you decompose tasks like booking transport and permission slips. This way of thinking applies to many subjects and real-life situations beyond computing.
计算思维是一种包含四项关键技巧的问题解决方法：分解（把问题拆成更小的部分）、模式识别（发现相似之处）、抽象（聚焦关键细节，忽略无关信息）以及算法设计（制定逐步解决方案）。例如，策划学校旅行时，你会把任务分解成预订交通工具和收集家长同意书等。这种思维方式可应用于计算机以外的许多学科和现实场景。
7. Algorithms and Flowcharts: Step-by-Step Solutions | 算法与流程图：逐步解决方案
An algorithm is a precise set of instructions to complete a task – like a recipe. In Year 7, you represent algorithms using flowcharts, which use standard symbols: oval for Start/End, parallelogram for Input/Output, rectangle for Process, diamond for Decision, and arrows for flow direction. You will learn to sequence instructions, make choices using 'if' conditions, and repeat steps with loops. Reading and designing flowcharts builds the logical thinking required for coding.
算法是完成一项任务的精确步骤集——就像一份菜谱。在 Year 7，你使用流程图来表示算法，流程图采用标准符号：椭圆形表示开始/结束，平行四边形表示输入/输出，矩形表示处理，菱形表示判断，箭头表示流程方向。你将学习如何顺序排列指令、使用“如果”条件做选择，以及用循环重复步骤。阅读和设计流程图能培养编程所需的逻辑思维。
Decision: Is temperature > 20°C? 判断：温度是否大于 20°C？
8. Introduction to Programming with Scratch or Python | 编程入门：使用 Scratch 或 Python
Programming puts computational thinking into action. Many schools begin with Scratch, a block-based language where learners drag and snap code blocks together to create animations and games. Key concepts include sequences, events (e.g. 'when green flag clicked'), loops ('repeat 10 times'), and variables (placeholders for data). If progressing to Python, students write simple text-based code like:
编程将计算思维付诸实践。许多学校从 Scratch 起步，这是一种基于积木的语言，学习者通过拖拽和拼接代码积木来制作动画和游戏。关键概念包括顺序、事件（例如“当绿旗被点击时”）、循环（“重复执行10次”）和变量（数据的占位符）。如果进阶到 Python，学生会编写简单的文本代码，如：
name = input("Enter your name: ")
print("Hello, " + name)
In both environments, debugging – finding and fixing errors – is encouraged, boosting resilience and attention to detail.
在两种环境中，都鼓励调试——查找并修正错误——以增强抗挫折能力和对细节的关注。
9. Binary and Data Representation | 二进制与数据表示
Computers use binary – a number system with only two digits: 0 and 1 – because their circuits can easily represent off (0) and on (1). Year 7 explains how these bits group into bytes (8 bits), and how binary numbers translate into decimal numbers that humans understand. A simple conversion example is:
计算机使用二进制——一种只有 0 和 1 两个数字的数制——因为电路可以轻松表示关 (0) 和开 (1)。Year 7 会讲解这些比特如何组合成字节（8 位），以及二进制数如何转换成人类能理解的十进制数。一个简单的转换例子：
1011₂ = (1 × 2³) + (0 × 2²) + (1 × 2¹) + (1 × 2⁰) = 8 + 0 + 2 + 1 = 11₁₀
Students also touch upon text representation using ASCII codes, where each character is assigned a unique binary number, reinforcing the idea that all data on a computer is stored and processed as binary.
学生还会接触用 ASCII 码表示文本，每个字符被分配一个唯一的二进制数，从而强化一个概念：计算机上的所有数据都以二进制形式存储和处理。
10. Handling Data: Spreadsheets and Databases | 数据处理：电子表格与数据库
Digital literacy includes managing and analysing data. In Year 7 WJEC, you learn to use spreadsheet software (e.g. Microsoft Excel or Google Sheets) to enter data, apply simple formulas like SUM and AVERAGE, and create charts. Basic database concepts are introduced through terms like fields, records, and queries. These skills are practical for organising information, whether it is tracking pocket money or a class survey.
数字素养包括管理和分析数据。在 Year 7 WJEC 课程中，你将学习使用电子表格软件（如 Microsoft Excel 或 Google 表格）输入数据、应用 SUM 和 AVERAGE 等简单公式并创建图表。还会通过字段、记录和查询等术语引入数据库的基本概念。这些技能对组织信息非常实用，无论是记录零花钱还是班级调查。
| Spreadsheet Term | 电子表格术语 | Example |
| Cell reference | 单元格引用 | A1, B4 |
| Formula | 公式 | =SUM(A1:A5) |
| Chart | 图表 | Bar chart, pie chart |
11. Creative Digital Projects | 创意数字项目
A significant part of Year 7 is applying computing skills in creative ways. Pupils might design a multimedia presentation, edit a short video, create a simple website, or develop an interactive quiz in Scratch. These projects combine technical ability with imagination, encouraging teamwork and communication. Assessment often looks at both the final product and the planning process, including storyboards, flowcharts, and reflections on design choices.
Year 7 很重要的一部分是以创造性的方式运用计算机技能。学生可能会设计多媒体演示文稿、编辑短视频、制作简单网站或在 Scratch 中开发互动测验。这些项目将技术能力与想象力结合在一起，促进团队合作与沟通。评估通常既关注最终作品，也关注规划过程，包括故事板、流程图以及对设计选择的反思。
12. The Future of Computing and Career Links | 计算机的未来与职业联系
The WJEC curriculum connects classroom learning to the wider world. Students discuss emerging technologies like artificial intelligence, robotics, and the Internet of Things (IoT). They also explore how computing skills lead to diverse careers – game design, cybersecurity, data science, healthcare technology, and more. Early exposure to these possibilities broadens career awareness and motivates learners to see computing as a tool for changing the world.
WJEC 课程将课堂学习与更广阔的世界相联系。学生讨论人工智能、机器人和物联网 (IoT) 等新兴技术。他们还探索计算机技能如何通向多样化的职业——游戏设计、网络安全、数据科学、医疗技术等等。尽早接触这些可能性可以拓宽职业认知，激励学习者将计算机视为改变世界的工具。
