ABSTRACT
Performance of almost any skill is greatly influenced by practice. Consider the profound influence of practice on such skills as reading, speaking a foreign language, computer programming, typing, or tennis. No matter how effective the initial instruction and guidance on a skill might be, unless learners have sufficient opportunity to practice the skill they may fail to achieve mastery. Some skills require a great deal of practice over a long period of time in order for learners to master the skill to the point that they can perform it readily in the real world situation.
