Basically for this is when you are trying to learn something and remember it you should not try and learn it and remember it all in a short period of time if it is difficult skill. For me this works best in real life skills such as how to drive or how to change the oil. My grandpa made me do this all the time so I could learn and not forget how to do it properly.
With this strategy it is very easy to learn subjects or recall it later in time. Because instead of remembering the specific word, you think about what subject it has to do with and then from there you can recall the specific word in that subject. I don' t know I did it all the time but it does it naturally and that's how I remember stuff about wildlife after years of not thinking about it because I can recall what I saw and know about a certain animal because of the chunking that occurs.
This is basically when you learn something and then fall asleep afterwards you will remember it because your mind will be thinking about it when you go to sleep. In US History we had to watch a series of episodes about the men who built america and I did this before I went to bed and the next day I was able to remember almost every detail about the show.
Detailing is exactly what it sounds like. You look at very detailed or descriptive images or writings and you are able to recall it because you learn multiple things about the subject and can at least recall a few of the details about that subject. This is another big thing in wildlife, identifying a crocodile from and alligator or an alligator from a cayman is difficult if you don't know what detail to look for. Like the size of the head and the color or the teeth, very detailed features need to know to identify a certain crocodilian.
For this strategy I have used this a lot in math class, if you ever heard of PEMDAS it is an Acrostic method of remembering. It stand for Please Excuse My Dear Aunt Sally. Which in turn you look at the first letter of that rym. Each first letter Parenthesis, Exponents, Multiplication, Division, Addition, and Subtraction, which is what you use for solving certain equations.
