a.3.1 data, information, and knowledge
Turn raw facts into powerful insights. Discover the journey from basic data to useful information and finally to the knowledge that drives smart decision-making.
You might think data and information are the same thing, but in Computer Science, they are worlds apart. Data is just the raw stuff - a jumble of numbers or letters with no context, like a list of temperatures (12, 15, 11). It’s meaningless on its own. It only becomes information when we organise it and give it meaning: "These are the daily temperatures in London." But the real magic happens when we analyse that information to spot patterns - like realising it’s getting warmer every year. That’s knowledge. This strand takes you through that journey, showing you how computers process raw input into the wisdom we use to make big decisions.
🧐 Sorry, I looked and there is nothing to see.
This section outlines the progressive curriculum mapping for Data, Information, and Knowledge. The framework traces a carefully structured pedagogical journey—from foundational sensory observations and data collection in early years , through to the advanced application of formal ontologies and automated knowledge extraction from Big Data at Key Stage 5. It explicitly utilizes the DIKW Pyramid to bridge the conceptual gap between raw facts and strategic wisdom , while embedding the critical GIGO principle to ensure students evaluate data quality, metadata context, and statistical validity in modern computational systems.
