Variables: What Are They and What Do They Do?

Have you ever seen an eLearning course or demo that seemed to know what you were doing? Maybe you entered your name on the first screen and saw it displayed in the course. Perhaps you made a decision early on and a character in a scenario remembered it later. Or maybe the course recommended follow up resources based on the concepts you had trouble with. You can thank variables for that.

What Are Variables?

Variables are a feature, in some eLearning authoring tools, that allow you to create advanced interactions. You can think of them as boxes for storing information. By themselves, they’re empty. But when you put information in them, they have value.

What Do Variables Do?

They “remember” information between screens. This lets you use that information to create advanced interactions. You can also display variables. Basically, this is letting the viewer see what’s “in the box.” That’s how you make a learner’s name appear in a course after they’ve typed it in.
