The Review feature was created with the objective to help learners memorize keywords and phrases from previously completed lessons through the use of Mango’s spaced repetition algorithm.
How does Review Work?
Once a learner has completed a lesson or sequence of lessons, phrases or words are automatically drawn from those completed lessons and placed into Review and Review cards are created. These Review cards are available on the day after the lesson or sequence of lessons was completed.
What is Spaced Repetition?
Spaced repetition is an evidence-based learning technique that is usually performed with flashcards. Newly introduced and more difficult flashcards are shown more frequently, while older and less difficult flashcards are shown less frequently in order to exploit the psychological spacing effect. The use of spaced repetition has been proven to increase the rate of learning.
What is the Forgetting Curve?
The forgetting curve hypothesizes the decline of memory retention in time. This curve shows how information is lost over time when there is no attempt to retain it.
To illustrate; imagine you meet someone and he says, "My name is Bob". You chat with him for 15 minutes and then walk away. On the next day, it's unlikely that you'll remember Bob's name, unless you made sure to repeat it to yourself several times.
