1. Course Overview | 课程概述
The Year 8 AQA Computing curriculum builds on the basics introduced in Year 7. Students explore how computers work, develop programming skills, learn about data representation, and become responsible digital citizens. The focus is on computational thinking – breaking problems into smaller parts, spotting patterns, and creating step-by-step solutions.
八年级 AQA 计算机课程建立在七年级引入的基础知识之上。学生将探索计算机的工作原理，发展编程技能，学习数据表示，并成为负责任的数字公民。重点在于计算思维——将问题分解成更小的部分，识别模式，并创建分步解决方案。
Assessment usually combines practical projects, written tasks, and online quizzes. Many schools use learner portfolios to track progress. Knowing the big picture helps you ask the right questions and celebrate small wins.
评估通常结合实践项目、书面任务和在线测验。许多学校使用学习档案袋来跟踪进度。了解全貌有助于您提出正确的问题并庆祝小的成功。
2. How Computers Work | 计算机如何工作
Your child learns about the main hardware components: the central processing unit (CPU), memory (RAM and ROM), storage devices, and input/output peripherals. They can explain the fetch-decode-execute cycle in simple terms and understand how data moves between components.
孩子学习主要的硬件组件：中央处理器 (CPU)、内存 (RAM 和 ROM)、存储设备以及输入/输出外设。他们能够用简单的语言解释取指令－解码－执行周期，并理解数据如何在组件之间移动。
Software is also covered – from the operating system that manages resources to application software such as word processors and web browsers. Encourage your child to point out these parts on a device you have at home; it makes the abstract concrete.
软件部分也涵盖其中——从管理资源的操作系统到文字处理器和网络浏览器等应用软件。鼓励孩子在家中的设备上指出这些部件；这能让抽象的概念变得具体。
3. Binary and Data Representation | 二进制与数据表示
Students discover that all data inside a computer is stored as binary digits (bits) – just 0s and 1s. They practise converting small denary (base-10) numbers into 8-bit binary, e.g. 5₁₀ = 00000101₂. Understanding why computers use binary links directly to hardware switches.
学生了解到计算机内部所有数据都以二进制数字（比特）存储——只有 0 和 1。他们练习将小的十进制数转换为 8 位二进制，例如 5₁₀ = 00000101₂。理解计算机为何使用二进制与硬件开关直接相关。
They also explore how text is represented using ASCII or Unicode character codes, and how images are broken into pixels with colour values. Simple binary addition is introduced. You can help by playing binary card games or using baking scales to show place value.
他们还探讨了如何使用 ASCII 或 Unicode 字符码表示文本，以及图像如何被分解为带有颜色值的像素。简单的二进制加法也会引入。您可以通过玩二进制卡片游戏或使用厨房秤来展示位值，提供帮助。
4. Programming Fundamentals | 编程基础
In Year 8, programming usually moves from block-based environments like Scratch to a text-based language, often Python. Students write programs that use variables, data types (integer, string, float), and selection (if-else statements). They also begin using definite iteration with for loops.
在八年级，编程通常从基于积木的环境（如 Scratch）转向文本语言，通常是 Python。学生编写使用变量、数据类型（整数、字符串、浮点数）和选择结构（if-else 语句）的程序。他们也开始使用带有 for 循环的确定迭代。
Key skills include debugging – finding and fixing errors – and writing comments to explain code. Encourage your child to talk through their logic aloud; this “rubber duck debugging” works wonders. You do not need to code yourself; just being a patient listener helps them clarify their thinking.
关键技能包括调试——查找并修正错误——以及编写注释来解释代码。鼓励孩子大声说出他们的逻辑；这种“橡皮鸭调试法”效果奇佳。您不需要自己编程；仅仅做一个耐心的倾听者就能帮助他们理清思路。
5. Computational Thinking | 计算思维
Computational thinking is a problem-solving approach that underpins the whole curriculum. It involves decomposition (breaking a task into manageable chunks), pattern recognition, abstraction (ignoring irrelevant detail), and algorithm design (creating a clear sequence of steps).
计算思维是一种贯穿整个课程的问题解决方法。它包括分解（将任务拆分成可管理的块）、模式识别、抽象（忽略无关细节）和算法设计（创建清晰的步骤序列）。
These skills are practised away from computers too. When you plan a family trip or organise a shopping list, involve your child and highlight the steps. Everyday activities become powerful thinking exercises.
这些技能也可以在脱离计算机的情况下练习。当您计划家庭旅行或整理购物清单时，让孩子参与进来并强调其中的步骤。日常活动就会变成强大的思维练习。
6. Networks and the Internet | 网络与互联网
Year 8 learners study how computers communicate. They compare LANs and WANs, learn about network hardware like routers and switches, and understand the role of protocols – sets of rules that allow data exchange, such as TCP/IP and HTTP. The Domain Name System (DNS) turns web addresses into IP addresses.
八年级学生研究计算机如何通信。他们比较局域网和广域网，学习路由器和交换机等网络硬件，并理解协议的作用——允许数据交换的规则集，如 TCP/IP 和 HTTP。域名系统 (DNS) 将网址转换为 IP 地址。
They might create simple network diagrams or simulate packet switching. Ask your child to explain what happens when you type a website address into a browser; retelling the journey from URL to webpage reinforces their understanding.
他们可能会创建简单的网络图或模拟数据包交换。请孩子解释在浏览器中输入网址后会发生什么；复述从 URL 到网页的旅程可以加强他们的理解。
7. Online Safety and Digital Citizenship | 网络安全与数字公民
A recurring theme throughout the AQA Computing curriculum is staying safe online. Students discuss strong passwords, recognising phishing and scams, protecting personal information, and the consequences of sharing too much. They also explore the ethical side of technology – copyright, plagiarism, and the digital footprint we all leave.
贯穿 AQA 计算机课程的一个反复出现的主题是保持网络安全。学生讨论强密码、识别网络钓鱼和诈骗、保护个人信息以及过度分享的后果。他们还探讨技术的伦理方面——版权、剽窃以及我们所有人留下的数字足迹。
Create an open dialogue at home. A good habit is to review privacy settings together and talk about respectful online behaviour. Many lessons include case studies about cyberbullying and how to report concerns.
在家中建立开放的对话。一个好习惯是一起检查隐私设置，并谈论尊重的网络行为。许多课程包括关于网络欺凌以及如何举报问题的案例研究。
8. Data and Databases | 数据与数据库
Students are introduced to the idea of a database as a structured collection of data. They learn about tables, records, and fields, and get hands-on practice creating simple queries to find specific information. Sorting and filtering are key skills.
学生被引入数据库的概念，即结构化的数据集合。他们学习表、记录和字段，并亲自动手创建简单查询以查找特定信息。排序和筛选是关键技能。
They may use a spreadsheet to test simple “flat-file” database ideas. To support this at home, you could look at a family recipe collection or a music playlist and discuss how you would organise it into fields such as “artist”, “title”, and “year”.
他们可能使用电子表格来测试简单的“平面文件”数据库概念。为了在家中支持这一点，您可以查看家庭食谱收藏或音乐播放列表，并讨论如何将其组织成字段，例如“艺术家”、“曲目”和“年份”。
9. E-Safety: Dealing with Misinformation | 电子安全：应对虚假信息
An extension of digital citizenship in Year 8 is evaluating online content for reliability. Pupils learn to check sources, cross-reference facts, and spot misleading headlines or manipulated images. This is increasingly important in a world of social media and AI-generated content.
八年级数字公民素养的延伸是评估在线内容的可靠性。学生学习检查来源，交叉核对事实，并发现误导性标题或被处理的图像。在社交媒体和人工智能生成内容的世界里，这一点越来越重要。
Practice this together when you stumble upon a viral story. Ask, “Who made this? What might their aim be? Can we find another site that says the same thing?” These critical questions are at the heart of the curriculum.
当您偶然看到一个热传故事时，一起练习这个。问一问：“谁制作的？他们的目的是什么？我们能找到另一个说同样内容的网站吗？”这些批判性问题正是课程的核心。
10. How You Can Help at Home | 家长如何在家辅导
You do not need to be a technology expert. Start by showing genuine interest. Ask your child to teach you something they learned in their lesson; teaching boosts their own understanding. Provide a quiet, organised workspace for any homework that involves a computer, and set clear screen-time limits.
您不需要成为技术专家。首先表现出真正的兴趣。请孩子教您一些他们在课堂上学到的东西；教别人能加深他们自己的理解。为任何涉及计算机的家庭作业提供安静、有条理的工作空间，并设定明确的屏幕时间限制。
Encourage logical games and puzzles – Sudoku, chess, or physical programming toys like micro:bit can extend learning. Many free resources exist, such as code.org and BBC Bitesize. When errors happen, praise effort rather than perfect results. Computing is about resilience and creativity.
鼓励逻辑游戏和谜题——数独、国际象棋或像 micro:bit 这样的实体编程玩具都可以扩展学习。有许多免费资源，例如 code.org 和 BBC Bitesize。当出现错误时，表扬努力而不是完美的结果。计算机学科关乎韧性和创造力。
11. Glossary of Key Terms | 关键术语表
