“Chunking” is an informational design concept that can be defined as, “dividing information into easy to remember portions.” The slightly longer definition is that people tend to remember things better if the information is presented in a concentrated format where larger subjects are divided up into smaller, logically related subtopics. A few examples of chunking might be an article that is divided into sections with sub headings, a bulleted list, or an outline.
Group related topics or subjects
This involves figuring out how you are going to organize the information. Say that you were creating a website about dogs. You might divide it into pet care and health, dog breeds, and training. The pet care and health section might be further divided into articles about grooming, taking care of minor injuries, and information about vaccinations your pet will need. The dog breed section might be divided up into articles about individual breeds and their specific needs, and the training section will of course involve training techniques from basic housebreaking and obedience to more advanced training.
Present the information in a modular fashion
Start small, and work your way up! Once you’ve taken care of the larger structure, break things down even more. Explain simple concepts, and then link those concepts together. Going back to the dog website example, you might explain why basic obedience training is important and then create articles explaining how to teach your dog to sit, stay, and so on. Refine each lesson in the same basic pattern of simple information to more complicated information.
Keep it simple; keep it short
Divide your content, and keep those bits of information corralled in small sections. If you are using a bulleted list, try to avoid having more than nine bullets per section. See if you can divide long lists into shorter ones, of no more than nine points. (Nine is something of a magic number. Studies have shown that your short term memory can hold up to nine points of information, but not much past that. The base is seven, plus or minus two.) The more complex a topic it is, the more it needs to be divided up.
Pare it down to the essential
Refine everything down to the most important details. Get rid of any tangents that aren’t directly related to the subject. Get rid of anything that isn’t essential to comprehension of the topic.
