What the Heck is Chunking?

When you go to write an online course, it is critical that you understand the concept of chunking. What do I mean by chunking in this case?

Definition of Chunking: Chunking is a principle that applies to the effective communication of information between human beings. It is particularly useful in the domain of written communication. It was first put forward in the 1950s by a Harvard psychologist named George A. Miller. He published a landmark journal article entitled "The Magical Number Seven, Plus or Minus Two". Miller studied the short term memory. For example, how many numbers people could be reliably expected to remember a few minutes after having been told these numbers only once. The answer was: "The Magical Number Seven, Plus or Minus Two".

In terms of eLearning, chunking means breaking up the text and culling it down to the essential so readers do not see a solid block of text. Content should be presented in informational units that are small and easy to digest. Topics should address only one main idea. It is necessary to use plenty of subheadings and ensure that the main points are emphasized visually.

As you begin organize your course, start with creating an outline with all the sections and subsections. From there you can then begin to write each section.

Here is an example of an outline with headings and sub-headings:

Section 1: Overview and Objectives

Course overview

Learning objectives

Practice Vignette

 

Section 2: Defining Teams

What is a team?

Why is team work important?

Different types of teams

Basic features of a team

 

Section 3: Building a team

Section 4: Stages of Team Development

Section 5: Building Team Trust

How does trust foster teamwork

Section 6: Summary and Review Exercise

Remember – when writing content for eLearning – less is more and Chunking is the key!
