当孩子开始学习 Year 7 WJEC 计算机科学课程时，您可能想知道如何在家中辅导他们。本指南将拆解核心主题，从计算思维到数字素养，并为非专业家长提供实用建议，让您与孩子一起探索计算机科学教育。无需任何先前的技术知识——只需要愿意一起探索并提出问题。

1. What Is Computer Science in Year 7? | Year 7 计算机科学是什么？

Computer Science in Year 7 is not just about using computers; it’s about learning how to think logically, solve problems creatively, and understand the digital world. The subject introduces students to the fundamentals of programming, algorithms, data, and the hardware and software that power technology.

Year 7 的计算机科学不仅仅是使用电脑，更是学习如何有逻辑地思考、创造性地解决问题，并理解数字世界。这门学科向学生介绍编程、算法、数据以及驱动技术的硬件和软件等基础知识。

Students begin to see themselves as creators, not just consumers, of technology. They learn that a computer follows instructions (algorithms) and that they can write those instructions through code. This mindset builds confidence and curiosity.

学生开始将自己视为技术的创造者，而不仅仅是消费者。他们了解到计算机遵循指令（算法），并且可以通过代码编写这些指令。这种思维方式可以建立信心和好奇心。

As a parent, you can encourage this shift by asking questions like ‘How do you think this app knows what to show you?’ or ‘What steps would a robot need to make a sandwich?’. These conversations help link classroom learning to everyday life.

作为家长，您可以通过提问来鼓励这种转变，比如 ‘你觉得这个应用程序是怎么知道该向你展示什么内容的？’ 或 ‘机器人做三明治需要哪些步骤？’。这些对话有助于将课堂学习与日常生活联系起来。

2. Understanding the WJEC Curriculum Framework | 理解 WJEC 课程框架

The WJEC Year 7 Computer Science curriculum is designed to provide a broad foundation. It typically covers three main strands: Computational Thinking, Digital Literacy, and Computer Systems. Your child will explore how to break down problems, design simple algorithms, write and test programs, and understand the basic components of a computer and network.

WJEC Year 7 计算机科学课程旨在提供广泛的基础。它通常涵盖三大主线：计算思维、数字素养和计算机系统。您的孩子将探索如何分解问题、设计简单算法、编写和测试程序，以及理解计算机和网络的基本组成部分。

Key areas include online safety, programming constructs (sequence, selection, iteration), data representation (binary), hardware input/output/storage, and the responsible use of technology. The course emphasises practical, hands-on activities alongside theory.

关键领域包括在线安全、编程结构（顺序、选择、迭代）、数据表示（二进制）、硬件输入/输出/存储以及负责任地使用技术。该课程强调理论与实践并重的动手活动。

Assessment is often through project-based tasks, quizzes, and problem-solving challenges rather than just written exams. This means your child will be building a portfolio of work and developing skills over time. Your role is to support consistent practice and a positive attitude.

评估通常通过项目任务、测验和解决问题的挑战来进行，而不仅仅是书面考试。这意味着您的孩子将逐步建立作品集并培养技能。您的角色是支持他们持续练习并保持积极态度。

3. Online Safety and Digital Citizenship | 网络安全与数字公民

Online safety is a critical part of the WJEC syllabus. Students learn about protecting personal information, recognising cyberbullying, understanding digital footprints, and behaving responsibly online. These lessons are not just school tasks—they are life skills.

网络安全是 WJEC 教学大纲的重要组成部分。学生学习如何保护个人信息、识别网络欺凌、了解数字足迹以及负责任地在网上行事。这些课程不仅仅是学校任务，更是生活技能。

As a parent, you can reinforce this by having open conversations about what your child does online. Ask them to explain the types of data they should never share publicly, such as their address, school name, or passwords. Encourage them to think critically about the content they see and the people they interact with.

作为家长，您可以通过与孩子开诚布公地讨论他们的网络行为来强化这一点。请他们解释哪些数据永远不应公开分享，例如地址、学校名称或密码。鼓励他们批判性地看待所看到的内容和与之互动的人。

You do not need to be a tech expert to help. Setting simple family rules—like keeping devices in shared spaces, agreeing on screen-time limits, and discussing respectful communication—mirrors the best practices taught in the classroom.

您无需成为技术专家也能提供帮助。制定简单的家庭规则，例如将设备放在共享空间、同意屏幕时间限制以及讨论尊重的沟通方式，这些都与课堂上教授的最佳实践相呼应。

Review privacy settings together on games and social apps.

一起检查游戏和社交应用程序的隐私设置。
Practice creating strong, memorable passwords using a mix of characters.

练习使用混合字符创建强健且易记的密码。
Discuss scenarios: ‘What would you do if a stranger sent you a message?’

讨论场景：’如果有陌生人给你发消息，你该怎么办？’

4. Introduction to Computational Thinking | 计算思维入门

Computational thinking is the heart of problem-solving in computer science. It involves four main techniques: decomposition (breaking a problem into smaller parts), pattern recognition, abstraction (focusing on important information only), and algorithm design (creating step-by-step solutions).

计算思维是计算机科学中解决问题的心脏。它包括四种主要技术：分解（将问题拆分成更小的部分）、模式识别、抽象（只关注重要信息）和算法设计（创建分步解决方案）。

These skills are not exclusive to coding; they apply to everyday tasks. Baking a cake, tidying a room, or planning a journey all involve computational thinking. By pointing out these parallels, you help your child see that computer science is about logical reasoning, not just screens.

这些技能并非编程独有；它们适用于日常任务。烤蛋糕、整理房间或计划旅行都涉及计算思维。通过指出这些相似之处，您可以帮助孩子认识到计算机科学与逻辑推理有关，而不仅仅是屏幕操作。

Try a simple activity: ask your child to write instructions for making a jam sandwich as if you are a robot that can only follow exact commands. You will both laugh when you misinterpret ‘put the jam on the bread’ by placing the jar on the loaf! This teaches precision in algorithms.

尝试一个简单的活动：让您的孩子写一份做果酱三明治的说明，假设您是一个只能遵循精确命令的机器人。当您把 ‘把果酱放在面包上’ 误解为把罐子放在面包上时，你们都会笑起来！这教会了算法中的精确性。

5. Algorithms and Flowcharts | 算法与流程图

In Year 7, students learn to represent algorithms using flowcharts and structured English. A flowchart uses symbols like ovals for start/end, rectangles for processes, diamonds for decisions, and arrows for flow. This visual tool helps clarify the logic before any code is written.

在 Year 7，学生学习使用流程图和结构化英语来表示算法。流程图使用椭圆形表示开始/结束，矩形表示处理过程，菱形表示决策，箭头表示流程。这种可视化工具有助于在编写任何代码之前理清逻辑。

You can support your child by drawing flowcharts for daily routines. For example, design a flowchart for ‘Is it a school day?’ leading to ‘Get ready for school’ or ‘Sleep in’. Encourage them to predict outcomes and trace the paths through decisions.

您可以通过绘制日常例程的流程图来支持孩子。例如，为 ‘今天是上学日吗？’ 设计流程图，导致 ‘准备上学’ 或 ‘睡懒觉’。鼓励他们预测结果并追踪决策路径。

Common algorithm patterns in the WJEC course include sequence (step-by-step order), selection (if-then-else decisions), and iteration (loops). Use real-life parallels: a traffic light sequence is a loop; choosing an outfit based on weather is selection.

WJEC 课程中常见的算法模式包括顺序（逐步顺序）、选择（如果-那么-否则决策）和迭代（循环）。使用现实生活中的类比：交通灯序列是一个循环；根据天气选择衣服是选择。

6. Getting Hands-On with Programming | 动手编程实践

Programming brings algorithms to life. Year 7 students often begin with block-based languages like Scratch, which teach logic without the frustration of syntax errors. Some schools may introduce text-based Python early. The goal is to create sequences, use variables, make decisions, and control loops.

编程让算法栩栩如生。Year 7 学生通常从基于块的语言开始，如 Scratch，这种语言可以教授逻辑，而不会产生语法错误带来的挫败感。有些学校可能早早引入基于文本的 Python。目标是创建序列、使用变量、做出决策和控制循环。

You do not need to know how to code to help. Sit with your child as they experiment and ask them to explain their project. What does this sprite do when you click the green flag? Why did you use a ‘repeat’ block here? Articulating their thinking reinforces learning.

您不需要知道如何编程就能提供帮助。在孩子尝试时和他们坐在一起，请他们解释自己的项目。点击绿旗时，这个角色会做什么？你为什么在这里使用 ‘重复’ 积木？表达自己的想法可以强化学习。

Encourage debugging as a positive process. Errors are not failures; they are puzzles. When a program does not work as expected, ask: ‘What did you expect to happen? What actually happened? What might need to change?’ This is the scientific method applied to code.

鼓励将调试视为一个积极的过程。错误不是失败，而是谜题。当程序未按预期运行时，问：’你预期会发生什么？实际发生了什么？可能需要改变什么？’ 这就是应用于代码的科学方法。

7. Hardware, Software and Computer Components | 硬件、软件与计算机组成

Understanding what’s inside a computer helps demystify the technology students use every day. The WJEC curriculum introduces the central processing unit (CPU), memory (RAM and ROM), storage (hard drive, SSD), and input/output devices. You can compare the computer to a human body: CPU is the brain, RAM is short-term memory, storage is long-term memory, and input devices are senses.

了解计算机内部结构有助于揭开学生每天使用的技术的神秘面纱。WJEC 课程介绍了中央处理器 (CPU)、内存 (RAM 和 ROM)、存储设备（硬盘、固态硬盘）以及输入/输出设备。您可以将计算机比作人体：CPU 是大脑，RAM 是短期记忆，存储是长期记忆，输入设备是感官。

A simple at-home activity: if you have an old device, safely open it together and identify the parts (disconnect power first!). Even better, use online interactive diagrams of a computer’s motherboard. Label components like the CPU fan, RAM sticks, and graphics card.

一个简单的家庭活动：如果您有旧设备，安全地打开它并一起识别部件（首先断开电源！）。更好的是，使用计算机主板的在线交互式图表。标记诸如 CPU 风扇、内存条和显卡等组件。

Distinguishing between hardware (physical parts) and software (programs, apps) is fundamental. Discuss how an operating system like Windows or macOS manages hardware resources. Ask your child to list five pieces of hardware and five software applications in your home.

区分硬件（物理部件）和软件（程序、应用程序）是基础。讨论 Windows 或 macOS 等操作系统如何管理硬件资源。请孩子列出家中五件硬件和五个软件应用程序。

8. Data Representation: Bits and Binary | 数据表示：位与二进制

Computers store all information as binary numbers—strings of 0s and 1s called bits. Year 7 students learn why binary is used (on/off states in transistors) and how to convert small binary numbers to decimal and vice versa. They also explore how characters are represented (ASCII) and the concept of pixels in images.

计算机将所有信息存储为二进制数——由 0 和 1 组成的字符串，称为位。Year 7 学生学习为什么使用二进制（晶体管中的开/关状态），以及如何将小型二进制数转换为十进制，反之亦然。他们还探索字符如何表示 (ASCII) 以及图像中像素的概念。

This topic can feel abstract, but hands-on activities make it concrete. Use a set of cards with dots representing place values (1, 2, 4, 8, 16) to build binary numbers. For example, to show the number 13, you need cards 8, 4, and 1, so binary is 1101₂.

这个主题可能感到抽象，但动手活动能让它变得具体。使用一组带有代表位值 (1、2、4、8、16) 的点卡来构建二进制数字。例如，要表示数字 13，你需要卡片 8、4 和 1，因此二进制为 1101₂。

Decimal \| 十进制	Binary \| 二进制
0	0₂
1	1₂
2	10₂
3	11₂
4	100₂
5	101₂

Ask your child to encode their age in binary, or convert your house number together. You can also play ‘binary chess’ where each turn requires reading a binary coordinate. These playful exercises build fluency and confidence.

让孩子用二进制编码自己的年龄，或者一起转换门牌号码。您还可以玩 ‘二进制象棋’，每一步都需要读出二进制坐标。这些有趣的练习可以建立熟练度和信心。

9. Networks and the Internet | 网络与互联网

The WJEC course introduces the basics of computer networks. Students learn the difference between a LAN (Local Area Network) and a WAN (Wide Area Network), and how the Internet is a network of networks. They explore key hardware like routers, switches, and servers, and concepts such as IP addresses and the client-server model.

WJEC 课程介绍了计算机网络的基础知识。学生学习 LAN（局域网）和 WAN（广域网）之间的区别，以及互联网如何成为网络的网络。他们探索关键硬件，如路由器、交换机和服务器，以及 IP 地址和客户端-服务器模型等概念。

You can relate these ideas to your home network. Draw a simple diagram showing how your devices connect to the modem/router, which connects to the Internet Service Provider (ISP). Discuss how a request for a webpage travels from your browser (client) to a web server and back.

您可以将这些想法与家庭网络联系起来。画一个简单的图表，显示您的设备如何连接到调制解调器/路由器，而路由器又连接到互联网服务提供商 (ISP)。讨论网页请求如何从您的浏览器（客户端）发送到网络服务器并返回。

Understanding that the cloud is just someone else’s computer in a data centre helps demystify online storage. Encourage curiosity about how emails, video calls, and online games work behind the scenes. This builds a foundation for more advanced networking topics in later years.

理解云只是数据中心里别人的计算机，有助于揭开线存储的神秘面纱。鼓励对电子邮件、视频通话和在线游戏幕后工作原理产生好奇。这为以后几年更高级的网络主题奠定了基础。

10. Supporting Your Child’s Problem-Solving Skills | 培养孩子的问题解决能力

Computer science is essentially about solving problems with a blend of creativity and logic. When your child faces a difficult programming task or a tricky logic puzzle, resist the urge to give them the answer. Instead, guide them with strategies such as breaking the problem down (decomposition) and solving similar, simpler cases first.

计算机科学本质上是用创造力和逻辑来解决问。当孩子面对困难的编程任务或棘手的逻辑谜题时，克制住直接给他们答案的冲动。相反，用策略引导他们，比如将问题分解（分解）并先解决类似但更简单的案例。

Encourage a growth mindset by praising effort, not just correctness. Say ‘I like how you tried three different ways to fix that loop’ rather than ‘You’re a natural programmer.’ This helps them persist when they encounter bugs in their code or confusing concepts.

通过表扬努力而非仅仅是正确性来鼓励成长心态。说 ‘我喜欢你尝试了三种不同的方法来修复那个循环’，而不是 ‘你是个天生的程序员’。这有助于他们在代码中遇到错误或令人困惑的概念时坚持下去。

Set aside a regular ‘tech time’ where you both work on a small computational challenge. It could be a Scratch project, a logic puzzle, or even designing an algorithm for a board game. This shared experience makes learning social and enjoyable.

安排一个定期的 ‘科技时间’，你们一起解决一个小的计算挑战。可以是一个 Scratch 项目、一个逻辑谜题，甚至是为棋盘游戏设计算法。这种共同体验使学习变得社交和愉快。

11. Useful Tools and Resources for Home Learning | 在家学习工具与资源

There is a wealth of high-quality, free resources aligned with the WJEC approach. Scratch (scratch.mit.edu) is the go-to for block coding; its community is safe and creative. Code.org offers structured courses that reinforce sequencing and loops. For binary and logic, try CS Unplugged (csunplugged.org) for activities that do not require a computer at all.

有大量与 WJEC 方法相符的优质免费资源。Scratch (scratch.mit.edu) 是基于块编码的首选；它的社区安全且富有创意。Code.org 提供强化顺序和循环的结构化课程。对于二进制和逻辑，可以尝试 CS Unplugged (csunplugged.org)，那里有完全不需要计算机的活动。

Off-screen, consider board games like ‘Robot Turtles’ (younger siblings can join) or ‘Code Master’, which reinforce algorithmic thinking. For reading, the ‘Hello Ruby’ series blends storytelling with computing concepts, perfect for Year 7 students.

在屏幕之外，考虑棋盘游戏如 ‘Robot Turtles’（弟弟妹妹也可以加入）或 ‘Code Master’，它们强化算法思维。对于阅读，’Hello Ruby’ 系列将故事叙述与计算概念相融合，非常适合 Year 7 学生。

12. Fostering a Positive Tech Mindset | 培养积极的科技心态

Your attitude towards technology greatly influences your child’s. If you express anxiety about computers or dismiss your ability to understand them, your child may internalise that. Instead, model curiosity. Say ‘I don’t know how this works—let’s find out together.’ This transforms technology from a black box into a fascinating system.

您对技术的态度极大地影响着孩子。如果您表达出对计算机的焦虑或否定自己理解它们的能力，孩子可能会将其内化。相反，要表现出好奇心。说 ‘我不知道这是怎么工作的——我们一起弄清楚吧。’ 这会将被技术从黑匣子转变为迷人的系统。

Challenge stereotypes that computing is ‘only for boys’ or ‘only for those who love maths’. Emphasise that computer science combines art, logic, design, and empathy. Many great programmers are also musicians, writers, and artists. Everyone can bring something valuable to the field.

挑战关于计算 ‘只适合男孩’ 或 ‘只适合喜欢数学的人’ 的刻板印象。强调计算机科学结合了艺术、逻辑、设计和同理心。许多优秀的程序员同时也是音乐家、作家和艺术家。每个人都可以为这个领域带来有价值的东西。

Celebrate small victories: the first program that runs without errors, a creative solution to a logic puzzle, or even a well-organised folder structure. These moments build confidence and a love for lifelong learning in our digital age.

庆祝小的胜利：第一个没有错误运行的程序，逻辑谜题的创造性解决方案，甚至是一个组织良好的文件夹结构。这些时刻能建立信心，并在数字时代培养对终身学习的热爱。
