📚 Interdisciplinary Integrated Question Practice | 跨学科综合题型训练
Welcome to a special revision session that will help you tackle the kinds of interdisciplinary questions you might see in WJEC Year 7 Computer Science. These questions require you to apply computing concepts across subjects like mathematics, science, geography, art and music. By practising them, you will strengthen your computational thinking skills and see how computing connects to the wider world.
欢迎来到一个特别的复习课，帮助你应对 WJEC 七年级计算机科学中可能出现的跨学科题型。这些问题要求你将计算概念应用于数学、科学、地理、艺术和音乐等学科。通过练习，你将加强计算思维能力，了解计算机如何与广阔世界相连。
1. What are Interdisciplinary Integrated Questions? | 什么是跨学科综合题型？
Interdisciplinary questions blend two or more subject areas into a single problem or task. For example, you might need to use a spreadsheet to record science data, or write a program that solves a maths puzzle. In WJEC Computer Science, these questions test your ability to think computationally across different contexts. They often involve abstraction, pattern recognition, decomposition and algorithmic thinking. Becoming comfortable with these question types will boost your confidence in both computing and your other subjects.
跨学科问题将两个或更多学科领域融合到一个问题或任务中。例如，你可能需要用电子表格记录科学数据，或者编写一个解决数学谜题的程序。在 WJEC 计算机科学中，这些问题考验你在不同情境下进行计算思考的能力。它们通常涉及抽象、模式识别、分解和算法思维。熟悉这类题型会增强你对计算机以及其他学科的信心。
2. Maths and Computational Thinking: Binary and Algorithms | 数学与计算思维：二进制与算法
Computers store numbers using binary digits (bits) – e represented as 1100 in binary because 12 = 8 + 4. Here is a quick look at the conversion:
计算机使用二进制数字（位）存储数值——只用 0 和 1。在十进制和二进制之间进行转换是一项融合数学与计算机的关键技能。例如，十进制数字 12 可以表示为二进制 1100，因为 12 = 8 + 4。下面快速看一下转换：
12₁₀ → 1100₂
| Decimal | 十进制 | 8 | 4 | 2 | 1 |
| Binary | 二进制 | 1 | 1 | 0 | 0 |
You might also be asked to write a simple algorithm to add two binary numbers or to convert a decimal number to binary using repeated division by 2. This kind of practise sharpens your algorithmic thinking.
你还可能被要求编写一个简单的算法，将两个二进制数相加，或者通过反复除以 2 将十进制数转换为二进制。这类练习能磨练你的算法思维。
3. Data Logging and Sensors in Science | 科学中的数据记录与传感器
In science experiments, sensors connected to a computer can automatically record measurements like temperature, light intensity or pH level over time. The data is often stored in a CSV file and analysed using spreadsheet software. For instance, you might log the temperature of a beaker of water as it cools, recording a reading every minute. Using the spreadsheet, you can calculate the average temperature or draw a line graph to spot trends. This is a perfect example of computing supporting scientific enquiry.
在科学实验中，连接到计算机的传感器可以自动记录一段时间内的温度、光照强度或 pH 值等测量数据。这些数据通常存储在 CSV 文件中，并使用电子表格软件进行分析。例如，你可以记录一烧杯水在冷却时的温度，每分钟记录一次读数。利用电子表格，你可以计算平均温度或绘制折线图以发现趋势。这是计算机支持科学探究的完美例子。
Your task might involve identifying the sensor data type (real numbers) and choosing an appropriate chart. You would also apply computational thinking abstraction – ignoring minor fluctuations to see the overall trend.
你的任务可能包括识别传感器数据类型（实数）并选择合适的图表。你还会用到计算思维中的抽象——忽略微小的波动，把握总体趋势。
4. GIS and Digital Maps in Geography | 地理信息系统与数字地图
Geographic Information Systems (GIS) combine geography with computer technology. You can explore digital maps that use layers of data, such as roads, rivers and population density. In Year 7, you might use a simple grid reference system to locate points or plan a route. A computer program could ask you to input coordinates and then display a marker. This relies on understanding x and y position values and how images are made of pixels.
地理信息系统 (GIS) 将地理与计算机技术结合在一起。你可以探索使用数据图层的数字地图，例如道路、河流和人口密度。在七年级，你可能会用一个简单的网格参考系统来定位点或规划路线。一个计算机程序可能会要求你输入坐标，然后显示一个标记。这依赖于理解 x 和 y 位置值以及图像如何由像素组成。
10 grid. A simple algorithm can check if two coordinates overlap, using conditionals. This connects spatial awareness with programming logic.
想象一个寻宝游戏：玩家在一个 10×10 的网格上从 (2,3) 移动到 (5,7)。一个简单的算法可以利用条件判断语句检查两个坐标是否重叠。这就把空间意识和程序逻辑联系在了一起。
5. Image Representation and Pixels in Art | 图像表示与艺术中的像素
g, we represent images as a grid of numbers indicating the colour of each pixel. The number of bits used for each colour is the colour depth. If you use 4 bits per pixel, you can represent 2⁴ = 16 different colours. The total size of an uncompressed image can be calculated with a simple formula:
所有数字图像都由称为像素的小方块组成。在艺术与设计中，你可以通过设置每个像素的颜色来创作像素画。在计算机中，我们将图像表示为一个数字网格，每个数字指示一个像素的颜色。用于每种颜色的位数称为色彩深度。如果每个像素使用 4 位，你可以表示 2⁴ = 16 种不同的颜色。一幅未压缩图像的总大小可以用一个简单的公式计算：
Total bits = Width × Height × Colour depth
1024 bits, which is 1024 ÷ 8 = 128 bytes. This shows how art and computing work together.
例如，一个具有 4 位色彩深度的 16×16 像素图标将使用 16 × 16 × 4 = 1024 位，即 1024 ÷ 8 = 128 字节。这展示了艺术与计算机如何协同工作。
6. Sampling Sound in Music | 声音数字化与音乐
Sound is stored digitally by taking thousands of samples per second. The sample rate (in Hz) and the bit depth determine the quality and file size. In music technology, you choose settings to balance clarity and storage space. The formula to estimate uncompressed audio file size is straightforward:
声音通过每秒采集数千个样本来进行数字化存储。采样率（以 Hz 为单位）和位深度决定了声音的质量和文件大小。在音乐技术中，你需要选择设置来平衡清晰度和存储空间。估算未压缩音频文件大小的公式很简单：
File size (bits) = Sample rate × Bit depth × Duration (seconds)
or 40,000 bytes (40 KB). This is a wonderful way to connect computing with music lessons.
假设你以 8000 Hz 的采样率和 8 位的位深度录制一段 5 秒的声音片段。文件大小将是 8000 × 8 × 5 = 320,000 位，即 40,000 字节 (40 KB)。这是将计算机与音乐课联系起来的绝佳方式。
7. Logic and Puzzles: Conditionals and Flowcharts | 逻辑与谜题：条件判断和流程图
Logical reasoning is essential across many subjects, from solving maths puzzles to classifying animals in science. In computing, we use conditionals (if, else if, else) to make decisions. Drawing a flowchart helps you visualise the decision-making process. For example, you might design a flowchart to identify a type of triangle: ask for three side lengths, then check if they are equal, or if two are equal, using AND or OR operators.
逻辑推理在许多学科中都至关重要，从解决数学谜题到科学中对动物进行分类。在计算机中，我们使用条件语句（if, else if, else）来做决策。绘制流程图有助于你将决策过程可视化。例如，你可以设计一个流程图来识别三角形的类型：要求输入三条边长，然后使用 AND 或 OR 运算符检查它们是否全等，或是否有两条边相等。
- IF side1 = side2 AND side2 = side3 → Equilateral
- ELSE IF side1 = side2 OR side2 = side3 OR side1 = side3 → Isosceles
- ELSE → Scalene
This kind of puzzle builds logical thinking that you also use in mathematics and science.
这类谜题培养的逻辑思维同样会用在数学和科学中。
8. Networks and Communication: Sharing Information | 网络与通信：信息共享
Computer networks allow us to share resources like files, printers and internet connections. In a school network, devices are often connected to a switch or router using Ethernet cables or Wi-Fi. Each device has a unique IP address, such as 192.168.0.10. Understanding basic networking concepts ties into how you collaborate on group projects – whether sharing a document in geography or researching a topic in history.
计算机网络使我们能够共享文件、打印机和互联网连接等资源。在学校网络中，设备通常使用以太网线或 Wi-Fi 连接到交换机或路由器。每台设备都有一个唯一的 IP 地址，例如 192.168.0.10。理解基本的网络概念与你如何进行小组项目合作息息相关——无论是在地理课共享文档，还是在历史课研究一个话题。
You may be asked to sketch a simple star topology and label the components. You should also be aware of online safety rules, such as using strong passwords and recognising phishing emails – skills that apply in everyday digital life.
你可能被要求画出简单的星形拓扑结构并标注组件。你还应该了解在线安全规则，例如使用强密码和识别钓鱼邮件——这些技能适用于日常数字生活。
9. Databases and Surveys: Collecting and Analysing Data | 数据库与调查：收集和分析数据
Databases help us organise and search large amounts of information. A cross-curricular task might involve designing a database to store the results of a class survey about favourite hobbies, or recording measurements from a science experiment. You will need to identify appropriate field names and data types – for instance, 'Name' (text), 'Age' (integer) and 'Hand span' (real number).
数据库帮助我们组织和搜索大量信息。一个跨学科任务可能涉及设计一个数据库来存储关于最爱好的班级调查结果，或记录科学实验的测量数据。你需要确定合适的字段名称和数据类型——例如，“姓名”（文本），“年龄”（整数）和“手掌宽度”（实数）。
Writing a simple query, like ‘Find all students whose favourite sport is football and age > 11’, introduces you to the idea of filtering data using logical operators. This skill is very similar to sorting data in a spreadsheet during a maths or geography lesson.
编写一个简单的查询，如“查找所有喜爱足球且年龄大于 11 岁的学生”，向你介绍了使用逻辑运算符筛选数据的概念。这项技能与在数学或地理课上用电子表格排序数据非常相似。
10. Programming Project: Designing an Interdisciplinary Game | 编程项目：设计一款跨学科游戏
A great way to practise cross-curricular skills is to build a small game in Scratch or a similar block-based platform. Suppose you create a game that quizzes players on times tables or flags of the world. You will need to use variables to keep score, loops to repeat questions, and conditionals to decide if an answer is correct. Broadcasting messages between sprites connects to the idea of network communication.
练习跨学科技能的一个好方法是在 Scratch 或类似的积木式平台中构建一个小游戏。假设你创建一个测试玩家乘法表或世界各国国旗的游戏。你将需要使用变量来记录分数，使用循环来重复问题，并使用条件判断来决定答案是否正确。在角色之间广播消息与网络通信的理念相关联。
You might even include a simple calculator that uses the binary conversions you practised earlier. This kind of project shows how computing unites knowledge from maths, languages and geography.
你甚至可以加入一个简单的计算器，用到之前练习的二进制转换。这类项目展示了计算机如何将数学、语言和地理知识融合在一起。
11. Summary and Practice Tips | 总结与练习技巧
To master interdisciplinary questions, keep these tips in mind: always read the problem carefully and pick out the computing element (algorithm, data representation, logic). Relate it to what you already know from the other subject. Use flowcharts or pseudocode to plan your answer before writing detailed code. Practise binary and image/sound calculations regularly – they appear in many cross-topic contexts. Finally, discuss problems with classmates; explaining your reasoning helps deepen your understanding.
要掌握跨学科问题，请记住以下技巧：仔细阅读问题，找出计算机方面的元素（算法、数据表示、逻辑）。将它与你在其他学科中已知的知识联系起来。在编写详细代码之前，使用流程图或伪代码来规划你的答案。定期练习二进制和图像/声音计算——它们出现在许多跨主题的情境中。最后，与同学们讨论问题；解释你的推理有助于加深理解。
By linking computing with subjects you study every day, these question types become less intimidating and much more enjoyable. The skills you build now will support your progress in ICT, science, mathematics and beyond.
通过将计算机与你每天学习的学科联系起来，这些题型会变得不那么令人生畏，反而更有趣。你现在培养的技能将支持你在信息与通讯技术、科学、数学及其他方面的进步。
