Principle #2: The Contiguity Principle
The Contiguity Principle posits that learning happens when words are aligned with corresponding graphics (pictures, graphs, diagrams, maps, etc…)That is, place words and graphics side by side on the screen (meaning, contiguous in space).
Avoid separating text and graphics on scrolling screens. A poorly designed scrolling screen is where the text and graphics appear on different screens-the text is presented first and the graphic or illustration is presented next on another screen. To avoid this problem integrate the text and graphics. That is, use text boxes that displays the text when the pointer is placed over the graphics.
It is a violation of the Contiguity Priciple 1 to display feedback on a seperate screen from the practice or question.
