Thesearch for an all-inclusiveteaching approach for SLA isa heavily sought-after entity,butthegoalofcreatingsuchatheoryisoftenviewedasunreachableintheeyesof many professionalsin thefield.RebeccaOxfordin Celce-Murcia(2001)articulatesthat,an overallflawlessdesigncannotbeestablished,whenshestatedthatitisquitefoolishtothink thatasingleL2methodologycouldpossiblyfitanentireclassfilledwithstudents:whohavea rangeofstylisticandstrategicpreferences.However,giventhefactorsofstudents・・learning strategies・;educatorscanmakeconnectionstotheir・preferences・anduseteachingapproaches to suite their needs (p.359).Since this rationale is a more common belieftoday,itis importantforeducatorstobeknowledgeableofstudents・learningstrategies,therelationship betweenimplicitandexplicitlearningandthemostbeneficialteachingapproaches.
Tothisendweaskourselves:
・How hasimplicitandexplicitlearningbeenclassified? ・Whatareimplicitandexplicitlearningstrategies? ・How areimplicitandexplicitstrategiesinterrelated?
・Whichteachingapproachesadvocateimplicitandexplicitlearningstrategies? Background
Thedualism ofimplicitand explicitlearning hasbeen a topicofgreatcontroversy amongsttheoristsand hastypically been divided into two separatedomains,which have been classified with differentterminologiesto definethedichotomies.Oneofthemajor underliningcharacteristicsofateachingapproachisthelevelofimplicitnessorexplicitness itexemplifies,thusinstructorsshouldalignteachingapproachesandlearningstrategiesto aim atthecognitivestyleand learning preferencesoftheir students.Studentsmustbe preparedfortheeducation aheadofthem,andin which case,educatorsmustgetabetter understanding ofimplicitand explicitlearning and theteaching approachesthatemploy them.With somany waystodefineimplicitandexplicitlearning,itisconfusing how to makecleardistinctions;however,implicitandexplicitlearninghavebeenembodiedinsuch dichotomiesas:Smith・s(1998)classicand officialeducation,Brown・s(2006)consciousand unconsciouslearning,Brown・s(2006)focaland peripheralattention,and theirrelation to Bialystok・s(1978)・ModelofSecondLanguageLearning・.
ClassicandOfficialEducationDichotomy
Smith(1998),inTheBookofLearningandForgetting,describeslearningas・twovisions・of thoughtandexplainsthedifferentamountsofawarenessthatpeoplehaveinaneducational atmosphere(p.5).Hecoinedtheterms,theclassicview andtheofficialtheorytoexplainthe processofeducation.Theclassicview oflearningisconsideredtobemoreimplicitinnature, andasdescribedbySmith(1998),constituteslife-longlearningformorecomplexeducational tasks.In the classicalview,he states that students・learning happens effortlessly and
throughsocialinteractions.AccordingtoSmith(1998),officiallearningisexplicitlearning, recognizing thatforstudentstobecomeawareoftheirknowledge,itrequireshardwork, andstudentshavetomemorizefactsfortesting.Thistypeofexplicitlearningisubiquitous withintheeducationsystem today.However,hebelievesthattestinginhibitsprogressanditis unpremeditatedandfurtheradvocatesthatmostoflearning in lifehappensunconsciously whileinteractingwithothers;thusweshouldstrivetousemoreimplicitteachingapproachesin theclassroom (Smith,1998).
ConsciousandUnconsciousLearningDichotomy
Brown (2006)describes implicit learning as,absorbing knowledge without conscious effort;ornothaving ・awarenessofwhathasbeen learned・(p.292).In retrospect,Brown (2006)explainsthatexplicitlearningusesawarenesstointentionallyprocessinformation.In essence,thesetermsareseenastwodifferentrealmsdistinguishedonlybytheirpsychological state.AlthoughthesetheoriescoincidewithSmith・s(1998)observations,Brown(2006)believes thatboth typesoflearning included ・focusing on certain stimuli・(p.292).Thedifference being,explicitlearnersareincontroloftheirfocusandareconsciouslytryingtolearnthe topicathand,whereasimplicitlearnersareovertaken by thestimulusandlearn through experiencing thesituation.Along thesamelines,Krashen definesimplicitlearning asan unconsciousacquisition,whilestatingthatexplicitlearningisconsciouslearning(ascitedin Finkbeiner,1998).Krashentheorizesthatconsciouslearningcanonlybeusedasa・monitor・ andthatalllanguageacquisitioncomesfrom implicitlyprocessingtheinformation(Brown, 2006,p.294).Controversially,many othertheoristsstatethattherearedifferentlevelsof consciousnessand unconsciousnessrequired for differentlanguageacquisition tasks,and these processes have not been completely defined (Brown,2006).What we know from researchisthatthemostcomplexlearninghappenswhenweareunconsciousoftheprocess athand(Finkbeiner,1998)andthough consciousandunconsciouslearning can beslippery terms(Brown,2006),wecansimplyview them asdifferencesinfocalattentiononstimuli. FocalandPeripheralAttentionDichotomy
Focaland peripheralattention was another attemptofdescribing how implicitand explicit learning were interrelated. Previously in SLA, focal attention and peripheral attention,compared with explicitand implicitlearning,wereseen asbeing synonymous. However,Brown(2006)warnsaboutsomeofthe・pitfalls・whenmakingoversimplifications, ashestatesitisveryimportanttonotethatinvirtuallyeveryactofperformingsomething, ・focaland peripheralattention actually occur simultaneously・ (p.301).In McLaughlin・s Model(1978)heagreeswithBrown・s(2006)rationale.(Table1.1)Whenwelearn,wecannot distinguish between implicitness and explicitness,because they vary depending on the contextofthelearningsituation.Furthermore,implicitandexplicitlearninghappenatthe
sametimeduetothenatureoflanguageacquisition.Theideathatthereisa・monitor・or ・consciousmind・ thatcan only makeadjustmentsor processexplicitinformation seems merely theoretical(Brown,2006,p.294).Thus,in thiscase,Krashen・sdistinctionsbetween learningandacquisitionhavebeenseenasempiricallyunverifiable.Itismorewidelyaccepted thatimplicitandexplicitlearningareoverlappingentitiesascanbeseeninTable1.1.
TheModelofInteractingKnowledge
Inacognitiveattempttounifyimplicitandexplicitlearning,Bialystok(1978)createda modelexplaining how explicitand implicitlearning coincide(Fig.1).In Bialystok・s(1978) model,implicitandexplicitlearningstrategiescanbeseenasinterconnectedentitiesthatare concurrently happening in unison.According to Bialystok (1978),implicit and explicit learning strategiesoperatein unison to processknowledge.Through repetition,language can movefrom being explicitly analyzedtostructuresthatareeasily accessed,butitwill nevertruly beinternalized likeimplicitknowledge.However,Bialystok (1978)admitsthat evenexplicitknowledgeisslowlyconvertedintoimplicitknowledgeaswemakenew cognitive associationsandinternalizetheinformation.OneofthecentralthemesofBialystok・s(1978) theorystatesthatwemustfirstacquireknowledgebeforewecanpossessit.Furthermore, thoughtherearemanyviewsofhow weacquirelanguageknowledge,thelearningstrategies designedforinputandintakearequintessentialintheactofSLA.Andso,understanding theteaching approacheswhich utilizelearning strategiescan defineatwhatlevelstudents areengagedinimplicitorexplicitlearning.

Discussion
Ononeendofthespectrum,asstatedbyBrown(2006),sometheoristswouldattestthat languageshouldneverbetaughtexplicitly,whileotherswouldencourageaheavilyimplicit method of language education.Many SLA researchers have attempted to explain and rationalize the positive and negative effects of implicit and explicit learning,but the complexitiesembodied in SLA haveproven too difficultto makegeneralizations(Brown, 2006).The mostimportantaspectis being informed aboutteaching approaches and the varyingrangesofimplicitandexplicitlearningstrategiesdrivingthem.Itisprevalentthat implicitandexplicitprocessesareusedatthesametime,ascanbeseeninFig.1(Bialystok, 1978).Looking atFig.2,wecan seearepresentation oftheteaching approaches,discussed earlierin Table1.2,andhow they arerelatedtoimplicitandexplicitlearning strategies. Fig.2showsthatsometeachingapproachesrepresentimplicitandexplicitlearningstrategiesat moreextremelevels.RebeccaOxford states,however,in SLA itwould bebettertomove towardsa・broadinstructionalapproach・andtooffermorebalancedteaching approaches with equal distributions (Celce-Murcia,2001,p.365). Thus,Audio-Linguistic,Affecti ve-Humanistic,CognitiveandCommunicativeApproachesofferthemostrangeofflexibilityfor learningstrategies.
LearningstrategiesareapredispositionthatcanfacilitateorinhibitSLA educationin terms ofcommunication,and willingness to take risks in participation.Also,learning strategiesareasetofskillsthatstudentsusetotacklelanguagetasks(Celce-Murcia,2001). AsRebeccaOxfordstates,aspectssuch asindividualisticandcollectivistic・manifestations・
instudentsshouldalsobetakenintoaccountwhenexpectingcertaintypesofinteractionin class(Brown,2006,p.202).Wecannotfitallstudentsintothesamebox,astheirlearning strategiesmayrangegiventheirsocioculturalidentity,ageandanumberofotherfactors. Theselearningstrategiescanalso・helpdeterminehow studentslearnasecondlanguage・ (Celce-Murcia,2001,p.359),soitisvitalthatteachershaveanoverview ofstudents・abilities.
Educators have two different options in order to cater to their students・learning strategies;eithertestthestudents・learningstrategiesatthebeginningoftheyearorteach new learning strategies in the classroom . Teachers can assess their students・learning strategies at the beginning of the semester using theStrategy Inventory forLanguage Learning1(SILL),whichcanbefoundinRebecca Oxford・s(1990)Appendix (Celce-Murcia, 2001).After giving the50-question SILL test,studentscan estimatetheir own learning strategiesusingtheSILL Rubric2.Educatorscanthenusethemeanofthestudents・learning strategiesandapplythecorrectteachingapproachesormethodstoensurethebestoutcomeof acourse.RebeccaOxfordalsoadvocatesinstructorsassessthemselvesastobeknowledgeable abouttheir・possiblebiases・(Celce-Murcia,2001,p.365).Secondly,educatorscan usethese resultstoseewhich learning strategiesthestudentsarelacking,asRebeccaOxford(1990) found,studentswhoweremoreawareoftheirlearning strategiesand adapted additional skills,didbetteroverallintheirlanguagelearning(Celce-Murcia,2001).Shealsostatesthat acquiring new learning strategiescan often beachieved by ・demonstrating when a given strategy m ightbeuseful・(Celce-Murcia,2001,p.363).Additionally,instructorscan try to getstudentstotransferstrategiesintootherskills,suchasusingpre-readinginpre-listening deduction (Celce-Murcia,2001).Teaching studentshow tousetheirlearning strategiesin a systematicwaygivesthem moreadvantagesforlanguageacquisitionandmoreflexibilityin theirlearninghabits.
Conclusion
Whilemany instructorsarecompletely awareofwhata schooldoes,whatteaching means,andhow tocreatewhatmightappeartobealesson plan;alloftheseaspectsare meaninglessifthateducatortakesawaylearningopportunitiesfrom hisorherstudents.If wearerequiring studentsto learn a second language,theteachershould berequired to know whatthecomponentsoftheteaching approachesare.Graham Crookesand Craig Chaudron would have also agreed with this point, as they advocate, ・・out-of-class・ knowledgeoflanguageteaching in areassuch asneedsanalysis,curriculum design,lesson planning・promotesuccessfulSLA teaching(Celce-Murcia,2001,p.29).Teachingapproaches thatsupporttheproperamountofimplicitandexplicitlearningstrategiesareanimportant
