There’s a limit to how much information a person can process or remember at a given time. The way training materials are designed should therefore consider cognitive load — the amount of processing power or working memory it demands of learners.

2 types of cognitive load

Cognitive load can be:

Intrinsic

Intrinsic cognitive load is an inherent part of the content; complicated topics or concepts demand some effort to understand. Instructional designers don’t control that. They do, however, control how they present the material. Some online training formats, such as microlearning, encourage designers to break complex content into small — manageable and digestible — chunks or units.

Extraneous

Extraneous cognitive load is not part of the content. The way content is presented can add unnecessary work for learners — potentially leading to cognitive overload. For instance, a graphic design that uses unusually styled buttons, menus, and other navigation aids that deviate from norms demands that learners invest effort in figuring out how to access the actual learning content. That effort saps processing power from the learners’ brains that could otherwise be used to understand the content. 

Design to reduce cognitive load

Accessible content

Creating content that is easy to use for a broad range of learners — those who are tech savvy and those who are not; experts in the topic and novices; people with a range of abilities; people from different cultures or whose native languages are different from the training language — is a great start.

Clean design

Keep visual design simple and clean. Make sure headings and subheadings set up a clear hierarchy and flow for the content and use navigation elements that are familiar and easy to identify.

Use plenty of white space, and make sure that every image and graphical element enhances the learning. Using purely decorative images and elements that are not related to the learning material is distracting and creates extraneous cognitive load.

Make it easy for learners to search for and navigate to specific content that is relevant to them.

Offer options

Give learners choices. This might mean offering multimodal content that allows learners to choose videos, interact with infographics or charts, or use transcripts and captions to review and better understand audio content.

It also could include enabling learners to control how content looks — providing ways to make text larger, increase contrast, and turn off animations or flashing graphics. Letting learners choose what works for them is a great way to reduce their cognitive load and free them to focus on learning.

Use meaningful interactivity

Activities are generally recommended as a way to engage learners, but this holds true — without contributing to cognitive overload — only if the activities are meaningful and useful. Making learners shoot a target to unveil a question is silly; asking them to match concepts with examples or definitions helps them use and remember relevant content.

Stick to what learners need to know

It’s easy to get carried away and include tons of information in an eLearning course or series of microlearning units. Instead, narrow in on what learners need to know. Move the nice-to-know information into a curated resources section or create job aids, reference guides, and other forms of performance support.

Reducing cognitive overload improves performance

Reducing the cognitive overload — avoiding extraneous elements that tax learners’ brains and tire them out — will improve training outcomes. Keeping training sessions short and focused both helps to reduce cognitive load and allows learners to stay focused on specific learning goals.

Games

Simple games layered on top of content

Scenario-based games that use the content

Leaderboards, competition

Fan excessive competition among employees or teams by offering large prizes for top performers and/or shaming those with lower scores

Challenge employees to beat their own past performance, or design a leaderboard that shows each employee only the four scorers above and below them

Points, rewards, badges

Award points or levels for completing sections of training or playing for a set number of minutes

Award levels, badges or points for recalling or applying content correctly, demonstrating mastery

  • Remember — bookmark, google, link, search
  • Understand — annotate, Boolean search, journal, tweet
  • Apply — chart, display, execute, present, upload
  • Analyze — attribute, deconstruct, illustrate, mash, mind map
  • Evaluate — comment, editorialize, moderate, network, post
  • Create — blog, film, integrate, podcast, program, publish

Comparison of the Three Levels of eLearning Content
Type
Off-the-shelf subscription libraries
Pros
  • Saves development time - you don’t have to create any courses yourself.
  • Good fit for a limited budget.
  • Quick to set up and launch.
  • Access to hundreds of courses on a wide variety of topics.
Cons
  • Users cannot make any changes to the pre-existing content.
  • Users do not own any of the content.
  • An overwhelming amount of courses and a short time in which to complete the training can create a higher likelihood of users experiencing learner fatigue.
  • Learners may view content that isn’t relevant to their learning objectives.
  • Time and resources can be spent curating your content library to suit your learners.
Type
Course customization
Pros
  • A premade course that is quick to set up and launch.
  • Customization options such as adding your logo, branding, choice of colors, or some fonts.
Cons
  • You do not own the content of the course.
  • You cannot make significant changes to the content of the course (e.g. adding your own images, data, or organization’s terminology).
  • You cannot make significant changes to the content of the course (e.g. adding your own images, data, or organization’s terminology).
Type
Fully custom courses
Pros
  • Completely tailored to meet your organization's audience, needs, and strategies.
  • You have limitless creative potential.
  • You own the original content/IP.
  • Prevent learner fatigue through personalization.
  • You can change, personalize, and maintain the courses however you want and at your discretion.
Cons
  • More expensive - custom courses are a bigger investment for both time and resources.
  • Learners will not have access to as many course options as quickly as they would through a library subscription.
  • A professional eLearning development team should be assigned to this project - either hired in-house or contracted.
