a.4.7.2 event driven programming
Don't call us, we'll call you. Learn how event-driven programs wait for user clicks, key presses, and sensor signals to trigger action, powering everything from games to GUIs.
Most modern apps don't just run from start to finish; they sit and wait for you to do something. Event-Driven Programming is all about reaction. Instead of a linear story, the code waits for an "event" - like a mouse click, a key press, or a sensor signal - and then triggers a specific listener function to handle it. It’s how your phone knows to take a photo when you tap the button, and how video games react instantly when you smash the jump key.
🧐 Sorry, I looked and there is nothing to see.
This section outlines the progressive curriculum mapping for Event-Driven Programming, tracing the pedagogical shift from rigid, sequential execution to a dynamic, reactive model. The framework moves from foundational cause-and-effect in early years to the mastery of the Event Loop, asynchronous operations, and Event Handlers at Key Stage 5. By explicitly separating the trigger from the logic, this strand ensures students understand how modern Graphical User Interfaces (GUIs) remain responsive while managing concurrent tasks, bridging the gap between basic coding and professional, interactive systems architecture.
