Practice is the act of rehearsing a behavior over and over, or engaging in an activity again and again, for the purpose of improving or mastering it, as in the phrase "practice makes perfect". Sports teams practice to prepare for actual games. Playing a musical instrument well takes a lot of practice. It is a method of learning and of acquiring experience. The word derives from the Greek "πρακτική" (''praktike''), feminine of "πρακτικός" (''praktikos''), "fit for or concerned with action, practical",〔(πρακτικός ), Henry George Liddell, Robert Scott, ''A Greek-English Lexicon'', on Perseus Digital Library〕 and that from the verb "πράσσω" (''prasso''), "to achieve, bring about, effect, accomplish".〔(πράσσω ), Henry George Liddell, Robert Scott, ''A Greek-English Lexicon'', on Perseus Digital Library〕 In American English, ''practice'' is used as both a noun and a verb, but in British English, there is a distinction between ''practice'', used as a noun, and ''practise'', used as a verb (see spelling differences). Sessions scheduled for the purpose of rehearsing and performance improvement are called practices. They are engaged in by sports teams, bands, individuals, etc. "He went to football practice every day after school", for example ==Common types of practice== Some common ways practice is applied: *To learn how to play a musical instrument *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 practise often enough, reinforcement fades, and he or she is likely to forget what was 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 practised many times before evaluation (a dance movement). 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Practice (learning method)」の詳細全文を読む スポンサード リンク
