How Learning Actually Works According to Science
Re-reading and highlighting feel productive but are weak learning methods. Retrieval practice, spacing, and interleaving create durable understanding.
How Memory Retention Really Works
Encoding creates memories; storage preserves them; retrieval strengthens them. Testing yourself embeds knowledge better than re-reading ever could.
Why Repetition Alone Does Not Create Knowledge
Repetition alone doesn't create knowledge because it's passive. Re-reading builds familiarity, not understanding. Knowledge requires active retrieval.
Spaced Repetition Explained
Review information right before you forget it. Each successful retrieval strengthens memory more than re-reading does. Spacing beats cramming.
