2. Computational Thinking | 计算思维
Computational thinking is the heart of the syllabus. Students learn to break down complex problems into smaller parts (decomposition), identify similarities and patterns (pattern recognition), focus on the relevant information while ignoring details (abstraction), and create step-by-step solutions (algorithms). For example, when designing a school timetable application, a student might decompose the task into user input, conflict checking, and display modules. Regular practice with puzzles and logic games helps reinforce these skills.
计算思维是课程大纲的核心。学生学习将复杂问题分解为较小部分（分解），识别相似性和模式（模式识别），关注相关信息而忽略细节（抽象），并创建分步骤的解决方案（算法）。例如，在设计一个学校课程表应用程序时，学生可能会将任务分解成用户输入、冲突检查和显示模块。经常练习谜题和逻辑游戏有助于强化这些技能。
The syllabus emphasises that computational thinking is not just for computer scientists; it is a transferable skill used in mathematics, science, and everyday decision-making. Teachers often encourage students to articulate their thought processes using 'think-aloud' strategies before writing any code.
大纲强调计算思维不仅仅是计算机科学家使用的技能，它也是一种可迁移的技能，用于数学、科学和日常决策中。教师经常鼓励学生在编写任何代码之前，使用“出声思维”策略清晰地表达他们的思考过程。
3. Programming Fundamentals | 编程基础
In Year 9, students typically build a solid foundation in text-based programming, often using Python, although block-based languages like Scratch may still be used for certain concepts. Core topics include variables, data types (integers, strings, Booleans), input and output, arithmetic operations, and selection statements (if-elif-else). Learners write programs that make decisions, such as a simple calculator that performs different operations based on user choice.
在 Year 9 阶段，学生通常建立牢固的文本编程基础，常使用 Python，不过像 Scratch 这样的模块化语言可能仍用于某些概念。核心主题包括变量、数据类型（整数、字符串、布尔值）、输入与输出、算术运算以及选择语句（if-elif-else）。学习者编写能够做出决策的程序，例如根据用户选择执行不同运算的简单计算器。
Iteration is introduced through both for and while loops. A typical exercise involves generating multiplication tables or summing a series of numbers. Students also learn to comment their code and adopt meaningful variable names, which are essential practices for creating readable and maintainable software.
