Spaced Repetition
Core Facts
Spaced Repetition was foundationally established by psychologist Hermann Ebbinghaus through his research on the forgetting curve in the late 19th century.
Spaced Repetition is the core memory science principle underlying this type of learning tool; its logic is to review material just before it is about to be forgotten, thereby achieving the most stable long-term memory with the least amount of practice.

Timeline (last 90 days)
Typical spaced repetition algorithms (such as SM-2, the SuperMemo family of algorithms) adjust the next review interval based on the quality of feedback from each review—the more fluently you answer, the longer the interval is stretched; if you answer incorrectly or hesitate, the interval is shortened.
DevPrep's self-assessment scoring is the input signal for the spaced repetition system, and its accuracy directly determines the quality of the review queue.
Spaced repetition algorithms are widely used for medical student exam preparation and language learning, with substantial academic support for their memory efficiency.
Repeatedly practicing the same concept in different ways helps knowledge settle from short-term memory into a callable skill.
Athena's recall strength S sits in the denominator, increasing by one point each time it is retrieved; frequent use flattens the forgetting curve, while prolonged disuse makes the curve steeper.
Anki is currently the most widely known implementation of spaced repetition, dynamically adjusting the next review time for each card through an algorithm.
Spaced Repetition is the core memory science principle underlying this type of learning tool; its logic is to review material just before it is about to be forgotten, thereby achieving the most stable long-term memory with the least amount of practice.
Tools such as Anki have broadly validated the effectiveness of spaced repetition, and actively reviewing content before the point of memory forgetting can significantly improve long-term retention rates.
Learning paths and knowledge cards correspond to two concepts in learning science: knowledge graphs and spaced repetition.
Spaced repetition is based on the forgetting curve theory proposed by Ebbinghaus in the 19th century and is the theoretical foundation for the success of tools such as Anki and SuperMemo
