In this instalment of the Online Learning Glossary, we’re looking at one of the biggest bugbears in the training community. Ebbinghaus’ Forgetting Curve, or simply The Forgetting Curve shows how information is lost over time when you don’t try to retain it.
If it wasn’t for the forgetting curve, your learners could take an eLearning unit once and it would stick in their brains first time.
But life would be boring if everything was that easy, so in a funny way, we’re lucky to have the Forgetting Curve!
First, let’s look at the history of the Forgetting Curve. In the late 19th century, German psychologist, Hermann Ebbinghaus tested his memory over various periods of time. Once he’d gathered all his data, he plotted it on a graph that looked a little something like this:
Now, contrary to appearances, Ebbinghaus didn’t invent a fun slide. He’d actually discovered the nature of memory loss over time. The graph illustrates that when you first learn something, the information disappears at an exponential rate, i.e. you lose most of it in the first couple of days, after which the rate of loss tapers off.
Once he’d discovered the exponential decline of memory, Ebbinghaus could identify the factors that contribute to it. The level of retention depends on a couple of things:
The Strength of the Memory
People can recall stronger memories for a longer period than weaker ones. When it comes to corporate training, the learning content should be highly relevant to each learner and it should have meaning.
The time that has passed since the information was learned
In a training context, the Forgetting Curve shows that learners will forget an average of 90% percent of what they have learned within the first month. And you were wondering why your training programme wasn’t having the impact you’d hoped it would!
How to Combat the Forgetting Curve
Now that we know how memory works, we can do something about it! Here are a few things you can do to improve recall in your training initiatives.
Reinforce the training regularly
Ebbinghaus discovered that information is easier to recall when it’s built upon things you already know. Every time you reinforce the training, the rate of decline reduces. Staging frequent training interventions helps solidify the information.
Make the information easier to absorb in the first place. If you learn something from an essay or an article, it’s easier to forget the meaning, or miss it entirely. Try to represent your information in a diagram, or create a video describing the learning objective.
Make it More Relevant
An off-the-shelf learning resource won’t have the same impact as a custom-made one. In every piece of training you produce, never forget the core purpose of your organisation, what we call the Epic Meaning. This works in two ways: the more relevant the training, the is easier it is to recall, and the common focus continually encourages the behaviours that are important to your business.
Make it More Interactive
People learn better when they’re actively involved than when they’re passive observers. If you don’t give your learners an opportunity to interact with the content, they’ll just drift off and lose concentration. Adding elements of gameplay to the learning is a great way to keep the learner involved and they might even enjoy the training!
