Elaborative Interrogation

Ask "why?" and "how?" about every fact you encounter. Instead of memorizing "mitochondria are the powerhouse of the cell," ask "why do cells need a separate organelle for energy production?" This simple habit forces you to connect new information to existing knowledge, creating richer memory networks. A meta-analysis of 21 studies found elaborative interrogation produced large and consistent learning gains across ages, subjects, and difficulty levels. It works especially well for factual learning in biology, history, and geography.
