Glossary:Acquisition rate

acquisition rate

speed of learning, usually expressed in items memorized per year per minute. For example, if 20 minutes a day result in memorizing 10,000 items a year, the acquisition rate is 500 elements/year/min (10,000/20). In SuperMemo, the acquisition rate may vary from 30-1000 items/year/minute depending on the difficulty of the material, forgetting index and the stage of the process. Acquisition rate may decrease substantially in the first year only to stabilize asymptotically as years pass by. See formula
