These elements work together to create solutions, complete processes, or deliver results. Learning how they interact prepares students for problem-solving in fields like engineering, computer science, and automation. 1. Input: Starting the System What It Is: Input is the information, resources, or energy that goes into a system to start a process. It can be entered manually (like pressing buttons) or automatically (like sensors collecting data). Example: Typing a search query into Google or scanning a product’s barcode. Real-World Applications: A car's ignition system starts when the driver turns the key (input). Smart homes collect data from motion sensors to control lighting. 2. Output: The System’s Result What It Is: Output is the final product, response, or result after the system processes input. It could be a physical object, a sound, or information displayed on a screen. Example: A text message sent to a friend, a document printed from a computer, or a song playing from a speaker. Real-World Applications: A 3D printer creates an object after receiving input from design software. A GPS system shows directions after a user inputs a destination. 3. Feedback Mechanism: Keeping the System on Track What It Is: Feedback is information sent back into a system to monitor, adjust, or improve its performance. Feedback helps systems stay on course and make corrections when needed. Feedback can happen automatically or through human intervention. Example: A thermostat that turns the heater off when a room reaches the set temperature. Real-World Applications: Smartwatches provide feedback by alerting users when they reach their fitness goals. Self-driving cars use feedback from sensors to adjust speed and avoid obstacles. How Input, Output, and Feedback Work Together Input: You press the button on a coffee maker to start brewing. Process: The machine brews the coffee. Output: The coffee is dispensed into your cup. Feedback: A sensor detects the water level and shuts off the machine when the brewing is complete. 4 Why It’s Important to Learn These Concepts 1.

Using an everyday object, the microwave, describe the input, process, output, and feedback 5  The role of algorithms in systems What is an Algorithm? An algorithm is a step-by-step set of instructions that a system follows to complete a task. Algorithms help computers, machines, and other systems operate efficiently by providing clear instructions for solving a problem or performing an action. How Algorithms Work in Systems: 1. Input: Data or instructions are fed into the system. 2. Processing: The algorithm works on the input by following the steps or rules. 3. Output: The system delivers the result of the algorithm’s work. 4. Feedback (if needed): The output can be fed back into the system to improve or modify future operations. Real-World Examples with Pictures: 1. Search Engine Algorithm (e.g., Google Search) Input: A user types a search query. Processing: The algorithm checks billions of web pages to find the most relevant ones. Output: A list of search results is shown to the user. Feedback: The search engine improves its algorithm based on what users click the most. 2. Social Media Feeds (e.g., Instagram or TikTok) Input: User interactions—likes, follows, and comments. Processing: The algorithm analyzes user preferences. Output: A personalized feed with recommended posts and videos. Feedback: Future recommendations improve based on how users engage. 6  3. Self-Driving Car System Input: Sensors detect traffic, speed, and road signs. Processing: The algorithm determines how the car should steer, accelerate, or brake. Output: The car moves safely to its destination. Feedback: The car adjusts based on real-time conditions (like sudden traffic). 4. Thermostat for Room Temperature Control Input: The current room temperature is measured. Processing: The algorithm compares the current temperature with the desired setting. Output: The heater or air conditioner is turned on or off. Feedback: The system checks the new temperature and makes adjustments if needed. Why Algorithms Matter Algorithms make complex tasks easier by breaking them into manageable steps. They help systems operate smoothly, whether it’s recommending content, making cars drive safely, or controlling the temperature in your room. Understanding algorithms helps us see how technology impacts our daily lives. 7  Section 2: Technology and Society Technology is now a central part of society, changing how we live, work, and connect.

It’s widely used in technology, business, and other fields to create products and services that make a real difference. Here are the five key principles: 1. Empathize What It Is: Understanding the people you’re designing for by putting yourself in their shoes. Empathy helps you see the problem from the user's perspective, giving you insights into their needs and challenges. Example: Interviewing people or observing their daily tasks to learn about their frustrations with existing solutions. 2. Define What It Is: Clearly identifying the problem you want to solve, based on the insights you gathered during the empathize stage. A well-defined problem is specific and user- centered. Example: Instead of defining the problem as “students have too much homework,” refine it to “students need a better way to manage homework efficiently to reduce stress.” 3. Ideate What It Is: Generating a broad range of ideas and solutions for the problem without immediately judging or filtering them. This stage encourages creativity and “thinking outside the box.” Example: Brainstorming different methods for homework management, like apps, planners, or study groups, even if some ideas seem impractical at first. 4. Prototype What It Is: Creating simple, tangible versions of your top ideas to test out with users. Prototypes can be anything from paper sketches to functional models and allow you to quickly gather feedback. Example: Developing a basic layout of a homework app on paper or using software to show what the main features might look like. 11  5. Test What It Is: Trying out your prototype with real users and collecting their feedback. This step helps you understand what works and what doesn’t, so you can make improvements and iterate on your design. Example: Sharing the app prototype with students, observing how they use it, and asking for their opinions to improve it further. Design Thinking in Action In a school project or real-world setting, you might use design thinking to address a challenge like creating an eco-friendly product or developing a community service plan. Each principle builds on the previous one, creating a cycle of continuous improvement. The goal is to create solutions that are not only functional but also meaningful and impactful for the people using them. Prototyping Solutions Prototyping is a crucial part of the design thinking process where ideas begin to take physical form. It’s the stage where abstract concepts become tangible, allowing designers to explore how a solution might actually work in the real world. Prototypes can be simple, like a sketch or a paper model, or more advanced, like a digital mockup or a basic version of a product. The goal is to create something users can interact with, so they can provide feedback that will help improve the design. Why Prototyping Matters Prototyping lets you quickly test and refine your ideas before investing in a final solution. It helps identify what works, what doesn’t, and what could be improved. This process of building, testing, and iterating helps ensure that the final product meets user needs and expectations. Types of Prototypes Low-Fidelity Prototypes: Simple versions, such as sketches or basic 3D models, which are fast and inexpensive to make. They allow you to test ideas early on and make quick changes. High-Fidelity Prototypes: Detailed and closer to the final product, often made digitally or with materials that resemble the actual product. They provide a more realistic user experience and help fine-tune specific details. Steps to Prototype 1. Identify Key Features: Decide on the main features or aspects of your solution that you want to test. 2. Create a Simple Version: Build a quick, simplified version that highlights those features. It doesn’t need to be perfect—just good enough to communicate your idea. 3. Test with Users: Let people interact with your prototype and observe how they use it. Gather feedback on what they like and where they face challenges. 4. Revise and Improve: Use the feedback to make changes, improving the design. You may go through several rounds of prototyping, each one bringing you closer to a refined solution. 12 Example of Prototyping in Action Imagine you’re designing a new app to help your friends manage their homework. Start with a simple paper sketch of the app layout to show what each button might do. Then, test it by asking your friends to “use” it as if it were real. Their reactions and suggestions can help you decide what to include in the next version. With each revision, your app prototype becomes clearer, more functional, and better suited to user needs. The Goal of Prototyping Ultimately, prototyping isn’t about creating a perfect product right away. It’s about learning and refining, so the final solution is as effective and user-friendly as possible. Iterative Testing and Feedback Iterative testing and feedback are key components of design thinking that help improve ideas and solutions through constant refinement. This process involves creating a prototype, testing it with real users, gathering their feedback, and making adjustments based on that input. By repeating this cycle, designers can continually enhance their solution, ensuring it better meets user needs and expectations with each iteration. Why Iterative Testing and Feedback Matter This approach is based on the idea that no solution is perfect on the first try. By testing early and often, you can identify issues and opportunities for improvement before finalizing a design. This saves time and resources and leads to a more effective, user-centered product. Steps in the Iterative Testing and Feedback Process 1. Build a Prototype: Create a basic version of your solution that users can interact with. 2. Test with Users: Allow actual users to engage with the prototype in a real or simulated setting, observing how they interact with it. 3. Gather Feedback: Collect feedback through interviews, surveys, or by watching how users engage with the prototype. 4. Analyze and Adjust: Review the feedback to identify common issues or suggestions, then make changes to the prototype. 5. Repeat the Cycle: With each new version, repeat the testing process to continually refine the design until it best serves its purpose. Example of Iterative Testing in Action Suppose you're designing a website to help customers find healthy recipes. After creating a basic version, you might test it with a small group of customers. From their feedback, you learn that they find the navigation confusing. You redesign the layout based on their comments and test again. Through several rounds of testing and feedback, the site gradually improves, making it easier for customers to use and find recipes. Benefits of Iterative Testing Enhanced User Experience: Each feedback cycle helps ensure the final product is user- friendly and intuitive. Increased Efficiency: Early testing prevents costly changes later on. Innovation: Continuous improvement allows for creative problem-solving and the discovery of new features or uses. 13 Conclusion Iterative testing and feedback are essential to the design thinking process, enabling continuous refinement and user-centered improvement. This cycle of testing and learning creates solutions that are not only effective but also responsive to the actual needs of users.

Algorithmic thinking is a way of solving problems by creating a series of steps or instructions, known as an algorithm. This approach helps break down complex problems into smaller, manageable tasks that can be followed systematically to reach a solution. Why is it Important? Algorithmic thinking is essential because it allows us to design efficient solutions to everyday problems, whether in technology, math, science, or even daily tasks. Learning to think algorithmically helps develop logical, step-by-step problem-solving skills, making it easier to tackle challenges in a clear, organized way. 15 Key Concepts in Algorithmic Thinking 1. Breaking Down Problems (Decomposition): Large problems can be overwhelming, so it helps to break them down into smaller, more manageable parts. For example, if you’re designing a website, you might split it into parts like layout, design, navigation, and content. 2. Identifying Patterns (Pattern Recognition): Patterns are recurring elements or themes. By identifying them, we can reuse solutions and ideas, saving time. For example, in coding, patterns help us see where similar code can be used in multiple places. 3. Creating Steps (Sequencing): Sequencing means arranging instructions in the right order. A recipe is a great example: following steps out of order can lead to a poor result. Likewise, algorithms need to be structured so each step follows logically from the one before it. 4. Making Decisions (Conditional Logic): Often, we need to make choices within our algorithms based on certain conditions. For example, an algorithm might say, “If the user clicks on a button, then display a message.” These if-then statements help tailor solutions based on different situations. 5. Optimization: Finding the most efficient way to achieve results is key in algorithmic thinking. Optimization helps ensure that an algorithm completes a task in the fastest or least resource-intensive way. Example: Algorithm for Making a PB&J Sandwich Imagine creating an algorithm to make a peanut butter and jelly sandwich. Here’s a simple breakdown: 1. Gather ingredients: bread, peanut butter, and jelly. 2. Spread peanut butter on one slice of bread. 3. Spread jelly on the other slice. 4. Place slices together with spreads facing each other. 5. Cut sandwich if desired. This basic algorithm has clear steps that lead to a specific outcome: a sandwich! Flowcharts and Process Diagrams What Are Flowcharts and Process Diagrams? Flowcharts and process diagrams are visual tools used to represent the steps in a process or decision-making path. They help simplify complex workflows by breaking them down into clear, visual steps. Each step in a flowchart or process diagram is typically represented by different shapes, such as ovals, rectangles, diamonds, and arrows that connect each step, showing the flow of the process. 16 Why Are They Important? Flowcharts make it easier to understand how a process works by: Clarifying each step in a sequence Showing how decisions impact the flow Identifying potential areas for improvement Making troubleshooting and debugging easier Example Situations: Flowcharts are used across many fields, from computer programming to business management and even daily activities like planning a project or organizing a schedule. Common Flowchart Symbols: 1. Oval: Start or End of the process. 2. Rectangle: A task or action step. 3. Diamond: A decision point, often leading to different paths based on a yes/no or true/false condition. 4. Arrow: Shows the direction and flow from one step to another. How to Create a Flowchart or Process Diagram 1. Identify the Process: Choose the process you want to visualize, whether it’s making a decision, a workflow, or a sequence of actions. 2. List Each Step: Write down each step in the process, including decisions. 3. Choose Symbols: Use the appropriate shapes for actions, decisions, and the start/end points. 4. Connect the Steps: Draw arrows to show the flow and ensure each step connects logically. 5. Review and Simplify: Look over the flowchart to see if any steps can be simplified or if there’s a more efficient path. Example Flowchart: Deciding on Dinner Here’s a simple flowchart for deciding what to have for dinner: 1. Start (Oval): "Hungry?" 2. Decision (Diamond): "Do you want to cook?" a. Yes: Go to "Cook Recipe at Home" (Rectangle). b. No: Go to "Order Takeout" (Rectangle). 3. End (Oval): "Enjoy Meal!" Flowcharts like this one offer a clear, visual way to think through processes and make decision-making easier by outlining each option and its result. 17  Problem-Solving Using Algorithms When tackling complex problems, algorithms can serve as step-by-step guides for finding solutions efficiently. In basic terms, an algorithm is a sequence of instructions that solves a specific problem. For problem-solving, algorithms break down the overall task into manageable steps, guiding us through each phase of the process in a clear, logical order. How Algorithms Aid in Problem-Solving 1. Define the Problem: The first step is to clearly identify what needs to be solved. Knowing the exact nature of the problem helps in developing a focused algorithm. 2. Break Down the Problem: Divide the problem into smaller tasks or steps. This makes it easier to address complex issues by tackling one part at a time. 3. Set a Sequence: Arrange these smaller tasks in a logical order. Each step should follow the previous one in a way that leads to the solution. 4. Implement and Test: Once the steps are organized, try following the algorithm to see if it works as intended. Testing ensures that the algorithm solves the problem effectively. 5. Refine if Necessary: If the algorithm doesn’t solve the problem or could work faster or simpler, refine it. This might mean reordering steps, removing unnecessary actions, or clarifying instructions. Example of a Problem-Solving Algorithm: Finding the Shortest Route Let’s consider an everyday problem: finding the shortest route to school or work. An algorithm to solve this could look like: 1. Identify Options: List all possible routes. 2. Calculate Distance: Measure the length of each route or the time it takes to travel. 3. Compare Routes: Check which route has the shortest distance or takes the least time. 4. Make a Decision: Choose the route with the shortest distance or time. 5. Test the Route: Travel the chosen route to confirm it’s the quickest. By following each step in the algorithm, you systematically analyze and solve the problem of finding the quickest route. Make a Decision Test the Route Calculate Distance Compare Routes Identify Options 18 9. PRACTICE: Create a flowchart that represents a simple everyday process you go through regularly. You will write out each step of the process and organize it into a flowchart format. Instructions: 1. Choose a Process: Think about a common process or task you do every day. It could be something like: Getting ready in the morning Making a cup of coffee Completing a homework assignment Going to the grocery store Cleaning your room 2. Select a process that can be broken down into clear steps. List the Steps: Write out the steps involved in this process. Be detailed but concise. Think about what happens first, next, and last. 3. Organize the Steps into a Flowchart: Use the following template to organize your steps into a flowchart format. Write the steps in order, and decide where decision points (yes/no) might happen. For example, you might have a decision point like “Is the coffee brewed?” in the coffee-making process. Note: You may need to add more boxes for your process; that is okay. 19  Section 5: Critical Analysis of Technology Trends Major technology trends 1. Artificial Intelligence (AI) What is it?
