This refers to highly structured activities that are specifically designed to improve a particular aspect of technique, skill or performance. As a coach, you should be on hand to provide tailored feedback or (if the player is good at self-reflection) to act as a sounding board
Deliberate practice is usually associated with ‘elite’ performers and some athletes may not find it enjoyable (although working hard and seeing improvement can be very satisfying). As a result, your Foundation Phase sessions should focus on other types of play. However, if you feel that a child is ready and would benefit from deliberate practice, you could suggest an activity be attempted as homework.
