Chunking is a learning strategy where large information and data is deconstructed and broken down to its foundations, which allows the information to be remembered much easier, assisting the short term memory.
The brain can only hold so much information at once, and when more information enters the brain, it will most likely be forgotten (Malamed, 2009).
Chunking is a useful strategy that allows the brain the memorise more information at once, while not overloading or exceeding its limits. Although chunking is a positive learning factor, it is commonly misused and mistreated in design, where too much information and data is grouped together, forcing the user to go back and forth between pages (Harrod, 2008).
This creates unnecessary effort to find information that should simply be placed right in front of them, as misuse of chunking can sometimes eliminate information.
