Long breaks between drills which are non related, intensity is lower, performers get the chance to think and reflect on learning, fatigue is not an issue
Use when teaching serial or continuous skills as the performer will get mentally and physically fatigued and thus, needs time to recover to execute the skills effectively. Further, these breaks allow the learner to think about the sub-routines involved in the execution of their complex skills.
Practice needs to be varied so that the performer can come into contact with a range of experiences. Relevant experiences are stored in long term memory and can be used to modify long term memory.
Performer attempts the whole skill, then practices the skill in parts or sub routines and then puts them together again to practice the skill as a whole
Progressive-Part method is very good for helping the performer learn complex, serial skills and externally paced skills as the performer can learn each individual part and then chain them together
