This article provides coaches with a guide for using technology and imagery to improve athletes' sport performance of closed motor skills. During the associative phase of skill learning, when young athletes are still learning to refine their technique, it can be difficult for coaches to change athletes' movements and develop their sport skills. The use of technology -- specifically audiovisual applications -- and imagery may be an accessible and effective way for coaches to help athletes understand and adjust their movements. Implementing technology and imagery through iSCORE can help coaches: 1) simplify imagery basics, 2) create audiovisual recordings of the sport skill, 3) offer technical feedback that incorporates imagery, 4) reinforce imagery and skill progress through repetition, and 5) evaluate athletes' progress. Using iSCORE may provide additional support for athletes' development during an often long and sometimes difficult skill-learning period.
