Metacognitive Strategies in Class
ChristopherHellman
学習ストラテジーが英語教員の指導技術一つとして、広まってきている。しかしながら、 それらがどのように活用されるべきかについては、多くの問題がある。また、さまざまな研 究において、多様性(variable)の重要性が強調されている。本論では、学生間で見られる ストラテジーが十分に生かされていない使用例を検証し、多様性に関する情報提供のため に、その結果を分析した。そして、戦略アプローチを含む、成功へとつながるさまざまな要 因を議論した。
Introduction
LearningStrategies
Learningstrategieshavebecomealargelyacceptedpartoftheteacher’stoolkit,appearing inanumberoftextbooksandstudyguides.However,despitethelargenumberofstudiesthat havebeenconducted,thereisalackofclearempiricalevidencetosupporttheirroleinsecond languageacquisition(Ellis1994;Rees-Miller1994).Developingoutof‘goodlearner’studies, which studied the behaviour of ‘good’ language learners on the premise that it could be duplicatedandtaughttootherlanguagelearners,researchonlearningstrategiestendedto concentrateonthedifferentstrategiesusedbylearnersorthenumberofstrategiestheyused, equatingfrequencywithsuccess(Wenden1985;Rost&Ross1991;Dreyer&Oxford1996),but only a few of these studies succeeded in directly correlating strategy use with language improvements(exceptinthefieldofreading).Indeed,somestudies(Vann&Abraham1990) foundevidenceofextensivestrategyusenotonlyamonggoodlearners,butamongpoorlearners too.Thereisalsoevidencethatexplicitstrategyinstructionmaybeseenasunnecessaryora wasteoftimebythelearnersthemselves(Rees-Miller1994).
Despitethis,learningstrategieshaveprovedpopular,andtherangeofbehavioursincluded undertheheadinghasgrownfarbeyondthoseinitiallyidentified.Thishasresultedinseveral classificationschemes,perhapsthemostusefulbeingthecognitiveapproachdevelopedby Chamot&O’Malley(seeforexample,Chamotetal1996),whichdividesstrategiesintothree
categories:cognitive,whichdealswiththeprocessingofinformationandincludesstrategiessuch aspredicting,groupingandinferencing;metacognitive,whichistheexecutivefunctionand involvesmanagingthelearningprocess,includingmonitoringandevaluating;andaffective,which dealswithsocialandemotionalfactors.Thesedistinctionsprovideausefulstartingpointfor assessingstrategyuse.Wheremostapproachessufferisnotintheunderstandingofstrategies themselves,butinfailingtoaddresswhatastrategicapproachmightbe.Ifweacceptatypical definitionoflearningstrategiessuchasthatgivenbyChamot: “techniques,approaches,or deliberateactionsthatstudentstakeinordertofacilitatethelearningandrecallofbothlinguistic andcontentareainformation”(Chamot1987:71)wecanseehowbroadarangeofbehavioursthis actuallyincludes.Infactitcouldincludevirtuallyanytechnique,tiporstudyskill.Suchabroad definitiongiveslittlesenseofwhatconstitutesthe‘strategic’aspectoflearningstrategies.Given thatstrategyinitsgenerallyusedsenseimpliesgainingadvantageatminimalcost,thiskindof collectionoftechniquesseemstobelittlemorethanacatalogueofmethods,ratherthanwhat mightbecategorisedasastrategicapproach.
ThePresentStudy
Researchers of learning strategies recognise there are many “learner, context, task, teacherandtextvariables”(Rubin&Chamot1994:771),withoutgivingmanyindicationsofwhat theseare.Clearly,forateachertohaveconfidenceinthestrategiesthattheyareteaching,these variablesmustbeaddressed.Giventheconceptofastrategicapproachtostrategyuse,my interestinthepresentstudywasinidentifyingandexaminingasituationwherestrategyuse couldprovideaclearadvantagetostudentsandtoinvestigatesomeofthevariablesmentioned aboveinthehopeofclarifyingfactorsinvolvedinsuccessfulstrategyinstructionanduse.
Thetaskthatwaschosenwasonethathadexcitedmycuriosity.Studentsinvolvedina taskwouldaskforhelp,notrealisingthattheanswerstotheirquestionswereavailableonthe previouspageoftheirtextbook,intheanswertoanexercisetheyhadcompletedbarelyten minutesbefore.Thisseemedasituationwhereasimplestrategicinterventioncouldreaplarge benefits.Advisingthemtochecktheearlierexercisewasasimpleandtimeefficientexampleof metacognitivestrategyuse.AsthisseemedtoembodywhatIregardedasastrategicapproachto usinglearningstrategies,Idecidedtoinvestigatefurther,toseetowhatextentstudentswere actuallyusingtheresourcesattheirfingertipsandtowhatextentthiskindofstrategymight benefitthem.
TheTask
Thetaskconsistedoftwopartswhichwereundertakensequentiallyandsharedthesame theme.Theyweredesignedtoutilisesimilaroridenticalgrammaticalpatterns,sothequestions whichappearedinPart1couldbetransferreddirectlytopart2togivecorrectanswersin7out of10ofthequestions.Bothpartswerecompletedontheappropriatepagesofthestudents’ textbook.Part2appearedonthefollowingpagetoPart1,soitwasnecessarytoturnthepageto refertothemodelquestionsintheearlierpart.Thismadeiteasytoseewhenstudentsreferred toPart1.
Part1tooktheformofageneralknowledgequiz.Thequestionswerereadouttothe students,whowererequiredtowritethemdownandthensupplytheanswers.Thequestions werereadseveraltimesandstudentswereencouragedtoasktheteachertorepeatpartsthey didn’tcatchorexplainorspellwordstheydidn’tknow.Theteacherthenelicitedanswersfrom theclass,correctingthemasnecessary.
Part2consistedofaseriesofanswers.Studentswereaskedtoformaquestionthatwould matcheachanswer.Severalcorrectsolutionswerepossibleforeachanswer.Forexample,the answer‘12’producedquestionssuchas:
Howmanymonthsarethereinayear?
Howmanyisadozen?
Howmanystar-signsarethere?
Duringthistime,theteachercirculatedandgavehelpwhenitwasrequested.(Duringa normalclass,theteacherwouldhavebeenmoreactiveinhelpingstudents,butforthepurposes ofthestudy,refrainedfromofferinghelpifitwasnotrequested).Afterasuitablelengthoftime, answerswereelicitedorgivenbytheteacher,andstudentscheckedandcorrectedtheirwork. Subsequentlythestudents’booksweretakeninandtheworkchecked.
First,bothpartswerecheckedforaccuracy.Part2wasalsocheckedforrelevance- studentswererequiredtowritegeneralknowledgequestions,soquestionssuchas“Howoldis mydog?”(answer:12)or“Whatismyfavoritenumber?(Answer:12)weremarkedwrong.
Next,Part1andPart2werecomparedandnotetakenofwhichquestionsinPart2 appearedtohavebeencopiedfromPart1.Thesewerethendividedaccordingtowhetherthe modelsinPart1werecorrectornot,andwhetherthecopieswereaccurateornot.Onefinal figurewascalculated-whatscoreeachstudentwouldhavereceivedhadalltheircopiesbeen madeaccurately.Theresultswerethentabulatedaccordingtostudent.

Theresultsrecordedabovewentsomewaytowardsconfirmingmyinitialobservation abouttherelativelysmallamountofreferencetoprevioustasks,andalsoshedlightonsome surprisingaspectsofthisareaofthestudents’useofstrategies.
As noted above, there seemed to be no direct correlation between the incidence of copyingandthenumberofcorrectanswers.Thoughsomeofthestudentswhocopiedmoredid getgoodmarks,otherswhocopiedanequalnumberoftimesdidnot.Possiblefactorswhich wouldgotowardsexplainingthisincludethefactthattherearemanypossibleanswersforeach question,whichmeansthatthecorrectanswerdoesnotnecessarilyinvolveanyreferencetoPart

Successfulcopyingseemstodependontwokeyfactors:whichanswersarechosenas modelsandhowaccuratelythesemodelsarecopied.Althoughmoreofthecopieswereaccurate thannot,theproportionofinaccuratecopieswasfairlyhigh-morethanathirdofallcopieswere madeinaccurately.Ifwelookatthetotalnumberofwronganswersthatweretheresultofcopies (includingaccuratecopiesofincorrectquestions)thefigurejumpsto50%.Thiscombinedrateof success/failureissignificantbecauseitrepresentsthesuccessofcopyingasthestudentswould perceiveit.Notbeinginapositiontoanalysetheirownresultstoseewherethestrategyhad failed,theywouldobservethatsometimescopyingwassuccessfulandsometimesnot,inroughly equalproportions(thoughdifferingfromstudenttostudent).Thiswouldputcopyingintothe categoryofriskystrategiesandmightgosomewaytoexplainthelowincidenceofcopying amongstthestudents.
Lookingatthenumberofstudentswhomadeinaccuratecopies,wecanseethatitisfairly high:12outof17.Itisinterestingtonotethatthosewhodidnotmakemistakesincopyingwere typicallyhighscoring.Thoughthereappearstobesomecorrelationonthispoint,thereisno evidenceofdirectcausality,anditmightreasonablybeassumedthatstudentswhoexercisemore careinoneareaoftheirworkarelikelytodosoinothersandthustendtoscorehighlyontasks thatinvolveaccuracyinareassuchasgrammarandspelling.
The results which proved most surprising were those that showed the relationship betweenthecopiesofcorrectmodelsandthecopiesofincorrectmodels.Thedegreetowhich studentswereabletodistinguishbetweencorrectandincorrectmodelstocopyfromappears quitesophisticated.Thisisevenmoreapparentwhenthetotalnumberofpossiblemistakesis considered.Ifthestudentsassumedalltheanswerstothefirstexercisetobecorrect,wemight expectthatthechoiceofcorrectmodelstocopywouldreflecttheproportionofcorrectmodel questions:incorrectmodelquestionsinpart1,whichwas75:95.However,thiswasnotthecase. Theactualproportionwas43:9.Thesurprisingsuccessofstudentsinchoosingcorrectmodel answerstocopywasobscuredbyotherfactors.Itwentunnoticedintheclassroomandina preliminaryreviewoftheresultsasitwasnotreflectedinotherareasofthetask.Thiswas presumablyaresultofi)thelowincidenceofcopying,andii)theinaccuracyofcopying.This suggeststheusefulnessoffocussingstrategyinstructiononspecific(andnarrowlydefined)areas toachieveimprovedresults.

Thedegreeofcopyingwasalsorelevant.Wecanseefromfig.6thathadthestudents simplycopiedallthemodelsfrompart1indiscriminately,regardlessofwhethertheywere correctornot,theirscoreswould,inmostcaseshaveimproved(assumingaccuratecopies). However,thiswasnotthecasefor4ofthestudents,allofwhomimprovedtheirscorethrough copying the models they chose, and would have received increased benefit from accurate copying,butwhosescoreswouldhaveworsenediftheyhadchosentocopyindiscriminately.This bringshomethedangersofover-simplifiedstrategyinstruction,whereoneapproachistaughtas applicabletoeverystudent.Whatworksforsomestudentsisineffectiveforothers.Clearly,for thesestudents,instructiontocopyindiscriminatelywouldhavereducedtheirscorebyinterfering withapartiallysuccessfulapproachwhichtheyalreadyemployed.Interestingly,thereduced scoresforthese4studentswouldbeamongthefivelowestintheclass,fallingfrom4to3;7to5; 7to6;and5to4respectively.Thepotentialdrop(ifallcopieswereaccurate)wouldbeeven greater:6to3;8to5;8to6and7to4.
Themajorityofstudents,however,standtogainfromthisstrategy-theincreasedcopying creatingsubstantialadvantage.Thisisparticularlyevidentinthestudentswhohadthelowest scores.Theywouldhaverisenfrom2to7;2to8;1to5;and1to7respectively.Thegainsof otherstudentsrangedfrom1to3,withanaveragegainof2pointswithrespecttotheiractual scores.

Discussion
Theprecedinganalysisraisesanumberofquestionsthatbeardirectlyontheteachingof learningstrategies.Therearealsoseveralissuesthataresuggestiveoftheneedforfurther research.
Firstitisnecessarytosayawordortwoabouttheflawsofthisresearch.Primaryamongst theseisthattheresultscannotclaimtoshowunequivocallywhichanswerswerecopiedand whichwerenot.SimilaritybetweenmodelquestionsinPart1andquestionswrittenbystudents inPart2areassumedtobetheresultofcopying,butitispossiblethattheywerearrivedat withoutdirectreferencetoPart1.Thisassumptionisbasedonthesubjectivejudgementofa teacher-thoughthisisitselftheresultofafamiliaritywiththestudentsandlikelybehaviourin theclass,aswellasdirectobservationofthestudentsengagedinthetask.However,evenifsome oftheanswerswerewronglyascribedastheresultofcopying,theconclusionsregardingthe effectivenessofcopyingandthegainspossiblefromdoingso,remainvalid,asdomostifnotall, theotherobservationsonstrategyuse.Ifanything,theylendmoreweighttothevalueofthis strategyandreinforcetheconceptoftargetedstrategyinstruction
Someinaccuracymayalsohavebeenintroducedbyvaryingdegreesofhelpthatwere giventostudentsundertakingthetask.Asitwasconductedduringalessonandwasnotintended tobeatest,studentswerefreetohelponeanotherandasktheteacherforhelp.Thisisoneof theinevitablecorollariesofclassroomresearch,wheretheeducationofstudentsmustassume priorityoverresearch.Inthiscase,assuchinterventionwould(itishoped)haveservedto increasestudentscores,theconclusions,onceagain,remainvalid.
Asdiscussedabove,oneoftheproblemsfoundinresearchintolearningstrategiesis establishingthecircumstancesinwhichstrategiescanbeusedmostsuccessfullyandhowthey shouldbetaught.Infact,manyofthelesssuccessfulexamplesofstrategyinstructionappearto betheresultofablanketapproachtostrategyinstruction.Themostcommonantidotetothis (Chamot&Rubin1994)appearstohavegonetoofarintheoppositedirection,requiringan extensiveinvestmentoftimethatmightbebetterspentindirectlanguageinstructionand practice.
Myinitialaiminconductingthisresearchwastoidentifyanareainwhichsimple,time efficientstrategyinstructionmightproducemeasurableimprovementinresults.Further,Ihoped thisstrategywouldbebroadlyapplicableacrossarangeofsituations.Havingobservedstudents makinglittleuseofresourcesthatwerereadilytohand,Iassumedresultswouldshowthe efficacyofusingpreviouslycompletedworktosupplyanswersforthetasktheywereworkingon.
ThoughIanticipatedmorecopyingwouldproducebetterscores,Ihadnotrealisedhow inaccuratemanyofthecopieswere.Clearlythiswouldmaketheprimarystrategylesseffective. Fortunately,itseemslikelythatasimpleinterventioncouldimprovethesituationandproduce increased scores - this is supported by the results showing potential scores (fig.5). In instructionalterms,thiskindofinterventionisbothquickandeasy,andneedconsistoflittle morethanaverbalreminderdeliveredtotheclassortoindividualstudents.Ifitwasperceivedto beacontinuingproblem,morespecificinstructionalmethodscouldeasilybedevised.Thisis,of course,standardfareformostteachers,butitembodiestheessenceofstrategyinstruction- functionalefficiency.
Similarly,encouraginggreateruseofcopyingwouldonlyrequireasimplereminderthat themodelsforthequestionsforPart2couldbefoundbyturningthepagebacktoPart1.This couldbeexpectedtoproducemorecopyingand,assumingthecopieswereaccurate,increased scores.Indiscriminatecopying,thoughclearlyeffectiveinthemajorityofcases,wasshowntobe aflawedstrategyandnotuniversallyapplicable,thusprovidingausefulwarningagainstoverly prescriptiveinstructioninstrategyuse.Itsuggeststhatcaremustbetakeninthewaythe strategyisadvocated.Inthiscase,itwouldbeeasytoremindstudentsthatmanyofthe‘answers’ couldbefoundinPart1andadvisethemtocheckitiftheywerestuckorwhentheyfeltitwas appropriate.Ifeelitisimportanttorememberthatstudentsalreadypossessasetoflearning strategiesthathavebeensuccessfulinthepast.Introductiontonewstrategiesandwaysof learningispartofeducation,butforcingateacher’swayofdoingthingsontostudentsisnot alwaysappropriate.
Althoughcopyingprovedtobeeffective,andwouldhavebeenmoresohadthecopies beenmoreaccurate,theresultsshowthiswasnotnecessarilycleartothestudentsthemselves. Thismaypartlyexplainthecomparativelylowincidenceofcopying,asastrategythathadbeen triedinthepast,butdidnotprovetobeparticularlysuccessful.Itisalsopossiblethatthe studentswerenotsufficientlyconfidentofthecorrectnessofthemodelsinPart1toadoptthem asmodelsonamorewidespreadbasis.Theproportionofcorrectmodelsthatwerechosento copyseemstoimplysomedegreeofchoicewasinvolvedinthedecisiontocopyornot,rather thansimplyforgettingthattheoptionwasavailable.Itwouldbeinterestingtoseewhetheraset ofcorrectmodel‘answers’suppliedbytheteacherwouldproduceahigherincidenceofcopying. Ifso,thiswouldsuggeststudentconfidenceinthecorrectnessofthemodelisafactorinthe incidenceofcopying,andthuschangethethrustofinstructionfromawarenessofaresourceto trustingthatresource.
The surprisingly high ratio of correct models to incorrect models that were copied
indicatedahighlevelofproficiencyatdistinguishingcorrectanswersfromincorrectones.Thisis presumablytheresultofpreviousexperiencewiththistypeoftask,andsuggestsahighly developedsetofstrategiessuitableforthetypesoftasktheyhadtodealwithinearlierstagesof theireducation.Thelackofaccuracyincopyingmayindicatetheemphasisofmultiplechoice typequestionsoveronesthatrequiretheanswerstobewritten.Inthistask,however,thisskill wasobscuredasitwasusedatanintermediatestageofthetaskandnottranslatedintothefinal results.Thequestionofwhatotherskillsorstrategiesstudentspossessandwhetheritispossible toutilisetheminawaydirectlyrelatedtoclassobjectives,isonethatwillbeofgreatinterestto teachers.Althoughthisisatopicthatfallsoutsidethescopeofthisresearch,itseemsworthyof futureinvestigation.
Thequestionofstrategychoiceingeneralisveryimportanttotheimplementationof learnerstrategyinstruction.Thisstudyexaminedataskwhichcouldbeperformedeffectively throughtheuseofaparticularstrategy.Thefailureofmanystudentstousethisstrategywas easilyobservableandamenabletodirectintervention.Thepotentialsuccessofthestrategyand thusitsvalueandthereasonitcanbesuccessfullytaughtisthatitwassolittleusedbystudents intheclass.Inaclasswheremostofthestudentsalreadyusedthestrategyfreely,therewould belittletogainfromteachingittotheclassasawhole,thoughindividualstudentswhowerenot using it would still stand to benefit. The ability to ascertain relevant strategies and target studentsneedswouldappeartobeamajorindicatorofsuccess,suggestingneedsanalysisof somedescriptiontobeanecessarypartofsuccessfulstrategyinstruction.
Conclusion
Theresultsofthisstudymakeitclearthatthisparticularstrategydidconferanadvantage tousers,anddespitethelackofdirectcorrelationbetweenthenumberofcopiesandthefinal score,itwasclearthatmoreaccuratecopyingwouldhaveproducedhigherscores,andthat indiscriminate copying would have produced even greater gains on aggregate, (although significantly,thesegainswouldnothavebeenenjoyedbyallstudents,suggestingextracare shouldbegiventoensuringthatstrategyuseispresentedasanoption,andnotamust).However theeffectivenessofthestrategywascompromisedbystudents’inaccuracyincopying,whichwas anunexpectedcomplicationhighlightingtheimportanceofsubsidiaryskillsthatallowthemain strategytobeusedsuccessfully.
This raises several further questions about strategies and strategy instruction. For example,whatroledosubsidiaryskillsplayinotherstrategies?Isitmoreeffectivetotarget
strategiesingroupsratherthansingly?Whatproportionofstudentstypicallyexperiencenegative resultsfromusingstrategiesandhowcantheseeffectsbereduced?
Perhapswhatwasclearest,fromthepointofviewofateacher,isthatstrategiescanbe usefulifsensitivelyandimaginativelyapplied.However,maximumvaluecanonlybeobtained withafirmgraspofthepurposeofthetaskandknowledgeofthe‘chokepoints’,orwherethe studentsarehavingmostdifficultywiththetask.Withthiskindofdiagnosis,strategiesmaybe appliedatthepointwhereminimuminterventioncanproducethegreatestresult.Itisthiskind ofapproachtotheuseofthewidevarietyoftechniquescommonlycalledlearningstrategiesthat deservesthelabel‘strategic’.
