What affects knowledge retention?
Your ability to retain and apply all of your knowledge to succeed at certification tests, and at your job is affected greatly by how you learn that material and how well you apply the four cornerstones of knowledge retention. The four cornerstones of knowledge retention are:
Sensory Learning
Mental Acuity
Preparation
Repetition
Sensory Learning
Let’s start with sensory learning. The more senses that you can get involved in learning something, the better you will retain the information. Just reading it or hearing a lecture about it will certainly allow you to remember some of the information but putting both together can roughly double your retention. Below is a chart showing how sensory involvement improves your retention.
Lecture 5%
Reading 10%
Audio/Visual 20%
Demonstration 30%
Discussion 50%
Hands-on Practice 75%
Application 90%
*The numbers used in this chart are not derived scientifically but are anecdotal based upon my many years of experience.
We, as humans, tend to remember the first and last things that we hear and that means that simply hearing a lecture can only allow you to retain a fraction of the information. When we add in reading the material to our learning process, we basically double our retention. Now mix in a healthy dose of audio and visual aids such as charts, graphs, animations, and sound effects and we have nearly quadrupled our retention. Next, I want you to show me and I can up my retention to roughly six times just hearing it.
Up to now, we have just been using our senses of hearing and sight. It’s time to get a little more engaged. Let’s discuss what we just heard, read about, and were shown. Actively participating in the discussion of how this information applies to your job or future job gets your mind to start processing the data and figuring out how to use it and bumps up your retention to almost ten times where we started. We’re not done yet. Now it’s time to practice what you’ve just been shown and get another sense involved. So now we are hearing, reading, seeing, speaking, and touching about this information and our retention is nearing 75%. All that’s left to make us masters of the subject is to really apply it to solving problems and completing tasks.
Since there is such a big jump in retention from Demonstration to Hands-on, there is a dangerous thought that makes us just want to start there, after all I am a Hands-on Learner. Unfortunately there are no shortcuts here, just as there aren’t any in life. The effects are cumulative and build upon each other. And if you want to see the kinds of numbers expressed in the chart, you have to apply the other three cornerstones as well.
Mental Acuity
Mental acuity or sharpness helps us to learn by focusing our faculties on that task or tasks at hand. Mental Acuity is not a matter of how smart or well educated you are it is instead an application of all of your intellectual intelligence, emotional intelligence, and determination to a stated goal. It is being as sharp and focused as you can at each learning opportunity, whether during lecture, reading, demonstrations, or labs. If you apply all of your focus at each of these critical times, then you can begin see really impressive gains in your retention. So remove those distractions or move yourself away from them and really give it all you’ve got.
Preparation
What we do before we hunker down to learn is even more important to our success than what we do to learn new skills. Preparation means getting oneself ready. Ready to learn but ready to learn what? We need to know what we need to know and how much of that do we know. Preparing for class, tests, life is all the same. You have to answer these questions:
What do I really need to know?
How much do I know?
How am I going to bridge that GAP?
Start by getting the details about the class, the test, the task and the conduct an honest assessment of your skills and level of mastery. Once you have identified the gap, then you can start planning how to fill in the holes and that starts with a detailed study plan. We will take more about creating study plans a little bit later. But for now, just know that a well thought out study plan is your roadmap to success.
Repetition
Repetition is pretty self-explanatory. No one had to tell you what they meant on the shampoo bottle when it says “Lather, Rinse, Repeat as Needed”, so I won’t bore you with the details. Suffice it to say that repetition significantly benefits retention.
Until next time....Good Day, Good News and Goodnight!
