1. Introduction to the Cambridge Lower Secondary Computing Curriculum | 剑桥初中计算机课程简介
The Cambridge Lower Secondary Computing course (0860) provides a coherent and progressive framework that builds on primary computing experiences and prepares learners for IGCSE and beyond. It is not just about using software; it focuses on creating, analysing, and evaluating digital solutions.
剑桥初中计算机课程（0860）提供了一个连贯且递进的框架，该框架建立在小学计算机学习的基础上，并为IGCSE及后续学习做好准备。它不仅仅是使用软件，而是着重于创造、分析和评估数字解决方案。
The curriculum is built around a set of key strands that interweave theoretical knowledge with practical application. Learners are encouraged to become autonomous, creative problem-solvers who understand the ethical and social implications of technology.
该课程围绕一系列关键模块构建，将理论知识与实际应用相互交织。鼓励学生成为自主的、富有创造性的问题解决者，并理解技术的伦理和社会影响。
2. Aims and Underlying Principles | 课程目标与基本原则
The central aims of the KS3 Cambridge Computing curriculum are to develop computational thinking, enabling learners to reason logically and algorithmically. It also aims to cultivate digital literacy so that students can safely, responsibly, and effectively navigate the digital world.
KS3剑桥计算机课程的核心目标是培养计算思维，使学生能够进行逻辑和算法推理。它还旨在培养数字素养，让学生能够安全、负责任且有效地遨游数字世界。
Another key principle is to provide a balance between understanding concepts and performing skills. Learners should not only know how computing technology works but also why it works that way, from binary representation to network protocols.
另一个关键原则是在理解概念和执行技能之间取得平衡。学生不仅应了解计算技术如何工作，还应了解它们为何这样工作，从二进制表示到网络协议。
Inclusivity and real-world relevance are woven throughout the syllabus. Activities are designed to appeal to a wide range of interests, showing that computing is a creative subject with applications in science, engineering, arts, and social sciences.
包容性和现实世界的相关性贯穿整个教学大纲。活动设计旨在吸引广泛的兴趣，表明计算机是一门具有创造性的学科，可应用于科学、工程、艺术和社会科学。
3. Strand: Computational Thinking | 模块：计算思维
Computational thinking is the problem-solving engine of computing. In this strand, learners master decomposition (breaking problems into smaller parts), pattern recognition, abstraction (focusing on important information only), and algorithm design.
计算思维是计算机学科问题解决的引擎。在此模块中，学生将掌握分解（将问题拆分为更小的部分）、模式识别、抽象（仅关注重要信息）和算法设计。
For example, a learner might be asked to develop a treasure hunt game. They decompose the task by listing steps, recognise patterns in movement, abstract the map into a grid, and design a step-by-step algorithm to navigate.
例如，可能要求学生开发一个寻宝游戏。他们会通过列出步骤来分解任务，识别移动中的模式，将地图抽象为网格，并设计逐步导航的算法。
Students also learn to represent algorithms using flowcharts and pseudocode. These tools help them communicate solutions clearly before writing actual code, reinforcing logical structure and sequence.
学生还将学习使用流程图和伪代码表示算法。这些工具有助于他们在编写实际代码前清晰地传达解决方案，从而强化逻辑结构和顺序。
4. Strand: Programming | 模块：编程
Programming brings computational thinking to life. The Cambridge curriculum encourages the use of both block-based languages (like Scratch) and text-based languages (such as Python) to solve problems and create interactive projects.
编程将计算思维付诸实践。剑桥课程鼓励使用基于块的语言（如Scratch）和基于文本的语言（如Python）来解决问题并创建交互式项目。
Learners progress from simple sequences to controlling selection (if-else statements) and iteration (loops). They handle variables, data types, and lists, building a solid foundation for future software development.
学生从简单的顺序结构逐步发展到控制选择（if-else语句）和迭代（循环）。他们处理变量、数据类型和列表，为未来的软件开发奠定坚实基础。
Debugging and testing are treated as essential programming skills, not afterthoughts. Students learn to systematically find and fix errors, use test plans, and reflect on the efficiency of their programs.
调试和测试被视为基本的编程技能，而非事后补救。学生学会系统地查找和修复错误，使用测试计划，并反思其程序的效率。
5. Strand: Data and Data Representation | 模块：数据与数据表示
Understanding how data is stored, processed, and interpreted is crucial. This strand covers binary, denary, and hexadecimal number systems, showing how all types of data – numbers, text, images, and sound – are ultimately represented as bits.
理解数据如何被存储、处理和解释至关重要。本模块涵盖二进制、十进制和十六进制数制，展示所有类型的数据——数字、文本、图像和声音——最终如何用位（bits）表示。
For instance, learners convert between binary and denary, perform binary addition, and explore how ASCII and Unicode encode characters. They also examine the representation of bitmap images using pixels and colour depth.
例如，学生将在二进制和十进制之间进行转换，进行二进制加法，并探索ASCII和Unicode如何编码字符。他们还会研究使用像素和色彩深度表示位图图像。
Data analysis skills are also developed. Students collect, organise, and visualise data using spreadsheets and databases, learning to use functions, filters, and simple queries to extract meaningful information.
数据分析技能也得到发展。学生使用电子表格和数据库收集、整理和可视化数据，学习使用函数、筛选和简单查询来提取有意义的信息。
6. Strand: Computer Systems and Networks | 模块：计算机系统与网络
This strand explores the hardware and software that make up a computer system. Learners investigate the central processing unit (CPU), memory (RAM, ROM), storage devices, and how these components execute the fetch-decode-execute cycle.
本模块探索组成计算机系统的硬件和软件。学生研究中央处理器（CPU）、内存（RAM、ROM）、存储设备，以及这些组件如何执行取指-解码-执行周期。
Networking concepts demystify how the internet works. Topics include types of networks (LAN, WAN), network topologies, protocols (TCP/IP, HTTP), and the physical infrastructure that enables global communication.
网络概念揭开了互联网工作原理的神秘面纱。主题包括网络类型（局域网LAN、广域网WAN）、网络拓扑结构、协议（TCP/IP、HTTP），以及实现全球通信的物理基础设施。
Learners also compare operating systems and software applications, understanding the role of system software in managing resources and providing a user interface. Cybersecurity basics are often introduced here, covering threats like malware and phishing.
