”

Mostadultswhoarelearningasecondlanguagewoulddisagreewiththisstatement.Forthem,learningalanguageisaverydifficulttask.Theyneedhundredsofhoursofstudyandpractice,andeventhiswillnotguaranteesuccessforeveryadultlanguagelearner.

Languagelearningisdifferentfromotherkindsoflearning.Somepeoplewhoareveryintelligentandsuccessfulintheirfieldsfinditdifficulttosucceedinlanguagelearning.Conversely,somepeoplewhoaresuccessfullanguagelearnersfinditdifficulttosucceedinotherfields.

Languageteachersoftenofferadvicetolanguagelearners:

“Readasmuchasyoucaninthenewlanguage.”“Practicespeakingthelanguageeveryday.”“Livewithpeoplewhospeakthelanguage.”“Don’ttranslate-trytothinkinthenewlanguage.”“Learnasachildwouldlearn;playwiththelanguage.”

Butwhatdoesasuccessfullanguagelearnerdo?

Languagelearningresearchshowsthatsuccessfullanguagelearnersaresimilarinmanyways.

Firstofall,successfullanguagelearnersareindependentlearners.Theydonotdependonthebookortheteacher;theydiscovertheirownwaytolearnthelanguage.Insteadofwaitingfortheteachertoexplain,theytrytofindthepatternsandtherulesforthemselves.Theyaregoodguesserswholookforcluesandformtheirownconclusions.Whentheyguesswrong,theyguessagain.Theytrytolearnfromtheirmistakes.

Successfullanguagelearningisactivelearning.Therefore,successfullearnersdonotwaitforachancetousethelanguage;theylookforsuchachance.Theyfindpeoplewhospeakthelanguageandtheyaskthesepeopletocorrectthemwhentheymakeamistake.Theywilltryanythingtocommunicate.Theyarenotafraidtorepeatwhattheyhearortosaystrangethings;theyarewillingtomakemistakesandtryagain.Whencommunicationisdifficult,theycanacceptinformationthatisinexactorincomplete.Itismoreimportantforthemtolearntothinkinthelanguagethantoknowthemeaningofeveryword.
