I have sad news for you guys. You cannot rely on your memory.
Everything you learn today will be partially forgotten in just a few days, and after 30 days
chances are that you have completely forgotten nearly everything you learned.
Luckily there is a solution to this problem and it's particularly useful for
language learners. It's called the Spaced Repetition System
and it's the main topic of today's video.
In the 19th century, Hermann Ebbinghaus discovered that our
brain tends to forget what we learn quite rapidly. To describe this phenomenon the
German psychologist coined the term "forgetting curve." Let's look at the
forgetting curve in action. Take a look at the graph on your screen.
The blue line shows what normally happens after a couple of days. Unfortunately it seems we
lose almost everything we have learned. In a nutshell, Ebbinghaus proved that
merely learning something once is not enough to remember it. If you want to
remember something the key is repetition. You need to
regularly review what you have learned if you want it to stay in your
long-term memory. Other researchers came up with a
mathematical model of Ebbinghaus's forgetting curve nearly a century later.
Based on that, an algorithm was developed. The algorithm prompts study sessions at
precisely the right time, which is just before you're about to forget what
you've learned. It can easily be adapted to users' needs and how difficult or
complex the information is. This algorithm is at the heart of the Spaced
Repetition System, or SRS, an extremely effective technique which is based on
the forgetting curve and on the fact that there is an ideal moment to review
information we have learned. If you review information too early, you'll
waste your time. If you review it too late you will forget it and will have to relearn it.
Plus, this moment will differ slightly for each person and each piece
of memorized information. That is where a SRS comes in handy, because it takes all
of this into account to predict the ideal time for revisions. Let me explain how
Spaced Repetition Systems work. I have already shown you this diagram.
The blue line shows what happens if you don't review what you learn. The Spaced
Repetition algorithm will first present you with information to review shortly
after you learned it, let's say between 8 and 24 hours, depending on the level of difficulty.
See how the second curve in red is very less steep than the first?
That means that with each reminder your capacity for memorization actually increases.
The algorithm will prompt you to review less and less often until the
information is stored in your long-term memory. So it's not surprising that many
memory researchers and language experts consider the Spaced Repetition System as
the most effective technique for sustainable memorization. That's why all
our apps and courses rely on an SRS algorithm, one of the most important
principles of our MosaLearning method. Every time you learn a word or phrase
with MosaLingua, you'll be reminded to review it just before you're about to forget it.
The system does the hardest part for you! I remember when I was
studying French and English I had to schedule my study sessions manually.
What a nightmare! Luckily, nowadays, computers and interactive resources like MosaLingua
are there to make our life easier and help us achieve better results, faster.
To sum up, if you want to remember something that review it regularly.
