Passive review
From Wikipedia, the free encyclopedia
Passive review is the opposite of active recall, in which the learning material is processed passively (e.g. by reading, watching, etc.).
for example when you want to improve your memory through Passive review, you learn a material in this way: you read a text today, so to don't forget it, you repeat it tomorrow and then you repeat it 4 days later and then 8, 16, 32, 64, etc day later. you don't ask yourself to explain content of the text, but only repeat and read it's contents. whatever you think to recall something, it is more likely to keep it more in your memory. Active recall is better than Passive review in this case. Passive review is a simple, easy and pleasant method but it is not effective, but Active recall is complicated(not all times), hard, and unpleasant(because forces you to recall something) method but it is highly effective and the materials that you have learnt with it, very fast and firmly sticks in your mind.
