It’s Easier To Learn When Numbers Are Visualized
In the not so distant past, data visualization was reserved for the scientific community. It helped researchers grasp the structure and relationships in large sets of data. But the explosion of complex information in most knowledge domains has changed all that.
The appreciation for visual thinking is growing and you can find many data visualizations in the popular media. Are we doing as much as we can to visualize information when we design learning experiences?
When information is visualized, it becomes tangible, which facilitates understanding. If you’re looking for new ways to visually explain complex and abstract concepts, I’ve found that it helps to play around with data visualizations. Here are four compelling examples where you might find inspiration. The last three are highly interactive.
Explaining 1 Trillion Dollars
Although it might be difficult to understand 1 trillion dollars, the BBC found a simple way to explain this numeric concept. It starts with a door mat as one unit and expands from there. Analogies like this are ideal for explaining complex numerical concepts. To see this visual in action, click on the But how big is that? button and then on each number category. It takes a minute for the whole thing to load. See 1 Trillion Explained.
How Different Groups Spend Their Day
The New York Times excels in interactive data visualizations. They have the staff and the vision to create interactive graphics that help you see information in new ways and to draw your own conclusions. This particular example may reveal much about the culture and society of the US. In terms of online learning, you get a lot here just by playing around. That alone is a powerful design lesson for all of us. See How Different Groups Spend Their Day.
Cost of Getting Sick
This visualization demonstrates the health care costs of various chronic conditions. Select each colored slice of the chart and drag the slider to a specific age. Notice how the chart itself changes size in relation to costs. Through the different combinations of data, we see things in new ways. In online learning, we need visualization tools like this to allow learners to explore, discover and learn on their own terms. See The Cost of Getting Sick.
