Which one is best Effective technique ?

[stepindustria]

School is for learning. But ironically, one of the things that people don’t really learn to do well in school was to learn. We are taught rote memorization and told to absorb it for arbitrary tests without being taught how to effectively absorb the material. And it seems as the methods we were actually taught in school aren’t all that effective. In a meta-analysis (a study analyzing other studies) published several years ago, 10 of the most popular learning techniques were studied and their effectiveness were ranked. The methods were categorized as low, moderate, or high in terms of utility (effectiveness) in absorbing learned material.
