So far, explanations of the proposed superiority of distributed practice schedules were primarily based on practical considerations (e.g. attention demands, fatigue).
A meta-analysis of 63 studies examining the effects of practice distribution in motor learning demonstrated the superiority of distributed practice and thereby confirmed Ebbinghaus's claim [ 4].
While the massed and the distributed practice group did not differ in performance, effects of practice distribution were evident in the regional oscillatory activity.
A distributed practice system, Hirsch explained, "is helpful in making the procedures second nature, which allows you to focus on the structural elements of the problem".
Many psychology studies have also shown that cramming material into a shorter time frame reduces learning, compared to distributed practice.
The benefits of distributed practice were first empirically demonstrated in the 19th century.
During the initial phase a model is designed (e.g. distributed practice) and implemented given the best knowledge in learning science.
Instead, they develop a habit of distributed practice, or a number of short study sessions over a longer period of time.
The benefits of spaced (or distributed) practice to learning are arguably one of the strongest contributions that cognitive psychology has made to education (Kang, 2016).
However, distributed practice is superior above massed practice, which is provided during a two-day course, for actually achieving these skills [23, 24].
The additive benefits of retrieval practice and spacing can be gained by engaging in retrieval practice multiple times (also known as distributed practice; see Cepeda et al., 2006).
