Practice is the act of rehearsing a behavior repeatedly, to help learn and eventually master a skill. Sessions scheduled for the purpose of rehearsing and performance improvement are called practices. They are engaged in by sports teams, bands, individuals, etc., as in, "He went to football practice every day after school". In British English, practice is the noun and practise is the verb, but in American English it is now common for practice to be used both as a noun and a verb (see American and British English spelling differences; this article follows American conventions).
Etymology The word "practice" derives from the Greek "πρακτική" (praktike), feminine of "πρακτικός" (praktikos), "fit for or concerned with action, practical", and that from the verb "πράσσω" (prasso), "to achieve, bring about, effect, accomplish".
Common types
To learn how to play a musical instrument (musical technique) To improve athletic or team performance To prepare for a public performance within the performing arts To improve reading, writing, interpersonal communication, typing, grammar, and spelling To enhance or refine a newly acquired skill To maintain skill To learn martial arts; kata and sparring are common forms of practice To master tasks associated with one's occupation (e.g. a cashier using a POS system) How well one improves with practice depends on several factors, such as the frequency it is engaged in, and the type of feedback that is available for improvement. If feedback is not appropriate (either from an instructor or from self-reference to an information source), then the practice tends to be ineffective or even detrimental to learning. If a student does not practice often enough, reinforcement fades, and they are likely to forget what they learned. Therefore, practice is often scheduled, to ensure enough of it is performed to reach one's training objectives. How much practice is required depends upon the nature of the activity, and upon each individual. Some people improve on a particular activity faster than others. Practice in an instructional setting may be effective if repeated only 1 time (for some simple verbal information) or 3 times (for concepts), or it may be practiced many times before evaluation (a dance movement).
Deliberate practice
Psychologist K. Anders Ericsson, a professor of Psychology at Florida State University, was a pioneer in researching deliberate practice and what it means. According to Ericsson:
