the power of a simple act: describing and organizing information in your own words.
I call this the textbook method as you’re essentially writing your own textbook on a topic. One thing I like about it is that it works nicely with different levels of required detail. Whether you just need to organize what’s known about a subject, or build a deeper understanding of how results are derived, the textbook method seems to extract an optimum amount of learning out of the time spent.
It also leaves a written record that’s easy to reference later when you need to deploy the information.
