Document Summary
What"s more important: keeping conditions constant or to generalize skill to different situations. A shortstop does not field ground balls with the same specifications throughout a game. Variability should be the focus of practice. Variability in movement and context is a necessary ingredient for skill development. A learner should be able to generalize a skill to a variety of situations. Variable practice enhances the development of the learner"s schema (schmidt, 1985: helps to select appropriate parameters for task. Skill acquisition is best achieved through the modification of constraints (newell. Force-producing task (shea & kohl, 1991: practice trials: constant practice group outperformed the variable practice group, retention test (learning): opposite effect, greater learning gains by variable practice group. Learning: a relatively permanent change in a person"s ability to execute a motor skill, as a result of practice or experience. Performance: a temporary expression of a skill.
