Benefits of mixed practice:
1 "Indeed there is evidence that the sequence of learning examples affects retention properties of the acquired skill. In a task where participants were asked to learn three different punch styles, people who trained with a random schedule—practice trials on all three styles were conducted intermittently—retained their performance better after 10 min and after 10 days, when compared with people who trained one style at a time (Shea and Morgan 1979Go). Similar results emphasizing the benefits of concurrent and intermixed training of several subskills as a whole were found in basketball shooting (Memmert 2006Go), pistol shooting (Keller et al. 2006Go), surgery training (Brydges et al. 2007Go), and three-dimensional spatial orienting (Shebilske et al. 2006Go). For example, in the basketball study, it was found that people had better acquisition when shooting positions were blocked but better retention of the skills when shooting positions were randomized." from Shea JB, Morgan RL.
