15 Chapter1:Rationale INTRODUCTION Students strugglewithlearningmathematicsisoftencastinanegativelight andviewedasaprobleminmathematicsclassrooms(hiebert&wearne,2003; Borasi,1996;Sherman,Richardson,&Yard,2009).Teachers,parents,educators andpolicymakersroutinelylookforwaystoovercomethe problem,seenasaform oflearningdifficulty,andattempttoremovethecauseofthestrugglethrough diagnosisandremediation(adams&hamm,2008;borasi,1996).fromthisone wouldhardlyexpectthatfocusingonstudents struggleinmathematicscouldbe viewedinapositivelightandasalearningopportunity. MathematicseducatorsandresearchersJamesHiebertandDouglasGrouws suggest,however,thatstrugglingtomakesenseofmathematicsisanecessary componentoflearningmathematicswithunderstanding(hiebert&grouws,2007). Theideathatstruggleisessentialtointellectualgrowthhasalonghistory.Dewey referredtotheprocessofengagingstudentsin someperplexity,confusion,or doubt (1933,p.12)asessentialforbuildingdeepunderstandingwhilePiaget (1960)wroteoflearners struggleasaprocessofrestructuringtheirdisequilibrium towardsnewunderstanding.cognitivetheoristshavereferredtocognitive dissonanceasanimpetusforcognitivegrowth(e.g.festinger,1957)whileothers haveidentifiedexperimentation(polya,1957)andsense making(handa,2003)as importantingredientsforunderstanding.hatano(1988)relatedcognitive incongruitywiththedevelopmentofreasoningskillsthatdisplayconceptual understanding.brownwellandsims(1946)argued,likedewey,thatstudentsmust haveopportunitiesto muddlethrough (p.40)intheprocessofresolving 1

16 problematicsituationsratherthanconditioningstudentsthroughrepetition.more recently,hiebert&wearne(2003)stated, allstudentsneedtostrugglewith challengingproblemsiftheyaretolearnmathematicsdeeply (p.6). Whilethephenomenonwecallstrugglemaybeinternal,itisalsoobservable inmostclassrooms.inthecontextofclassroominteractions,studentsmayvoice confusionoverdirections,thewordingofaproblem,thequestionbeingaskedor howtodeviseastrategy(polya,1957;lave&wenger,1991).studentsmayvoicea commentsuchas, Idon tgetit.ateachermaydetectstudents misconceptions thatyieldcompetingclaims,uncertainty,andcognitiveconflictinthestudents thinking(zaslavsky,2005).anerrorwhilesolvingaproblemmayleadtoan unreasonableanswerthatpuzzlesastudent(borasi,1996;inagaki,hatano,& Morita,1998).Astudentmaybeveryengagedinworkingonamathematics problembutthenreachanimpasseandget stuck (Burton,1984,p.46).What opportunitiesdotheseinstancesprovideforteaching? STRUGGLEANDLEARNING Struggleanditsconnectiontolearningarecentraltotheissueofhowto strengthenandimprovestudentlearningandunderstandingofmathematics (Hiebert&Grouws,2007).Twokeyfeaturesofclassroommathematicsteaching emergefromresearchthatlinksteachingwithstudents conceptualunderstanding: teachersandstudentsattendexplicitlytoconcepts;and studentsstrugglewithimportantmathematicalideas. (Hiebert&Grouws,2007) Byconceptualunderstanding,HiebertandGrouwsmean themental connectionsamongmathematicalfacts,procedures,andideas (2007,p.380).This 2

17 isincontrasttoproceduralunderstanding,whichreferstothe accurate,smooth, andrapidexecutionofmathematicalprocedures and intentionallydoesnot includeflexibleuseofskillsortheiradaptationtofitnewsituations (2007,p.380). Teachershaveanopportunitytofacilitatethedirectionthatstudents strugglescouldtake,eitherproductiveorunproductive.bystudents productive struggle,imeanstudents efforttomakesenseofmathematics,tofiguresomething outthatisnotimmediatelyapparent (Hiebert&Grouws,2007,p.287)asopposed tostudents effortmadewithoutdirectionorpurpose. STRUGGLEANDTASK Anexampleofstudents strugglethatcanbeproductiveinlearning mathematicsisgrapplingwithchallengingproblems(hiebert&wearne,2003). Mathematicaltasks,inparticularthosethatplacehighlevelcognitivedemandson studentsincludingmakingsenseoftheproblem,focusingonconceptsandconnections amongconceptsandsharing,explaining,andjustifyingone ssolution(boston& Smith,2009;Hiebert,Carpenter,Fennema,etal,1996;Ball,1993,Doyle,1988), provideaclassroomcontextforstudentstoengageininteractingwithproblems, classmates,andteacherstodeveloptheirconceptualknowledgeandunderstanding (Hatano,1988,Hiebert,1986;Zaslavsky,2005;Goldman,2009;Fawcett&Gourton, 2005).Tasksthatinvolveproblemsolvingcalluponstudents conceptualand proceduralknowledgetoconsideralternativestrategieswhenanapproachdoesnot work,examineone sresourcesandknowledgeuponwhichtobuild,reflectonone s thinking,andexplainandjustifyone ssolutions(nctm,2000;franke,kazemi,& Battey,2007;Kulm,1999;Kulm,Capraro,&Capraro,2007).Engagingstudentsin challengingtasksgivesstudentsopportunitiesto:strugglewithproblems;connect 3

STRUGGLEANDTEACHING Moststudies,however,suggestthatU.S.mathematicsteachingrarelyengages studentsinproductivestrugglewithkeymathematicalideas(e.g.hiebert&wearne, 2003;Rowan,Correnti,&Miller,2002;Stigler,Gonzales,Kawanaka,Knoll,& Serrano,1999).Schoolinstructionisoftenplaguedbyarushforquickanswers (Hiebert,Carpenter,Fennema,etal,1996;Dewey,1933)andfailstogivestudents sufficienttimetoengageinthinkingdeeplyaboutproblems(holt,1982).teachers maydesigntasksthatareintendedtoplacehighlevelsofcognitivedemandon students,butthenallowtaskstodeclineintheirdemandwhenstudentsencounter frustrationordiscomfort(henningsen&stein,1997;romagnano,1994;stigler& Hiebert,2004;Santagata,2005).Forexample,teachersstepinquicklywhenthey observestudentsstrugglingandexplainhowtodotheproblem,leavinglittleofthe challengingmathematicsforthestudentstodo(smith,2000).classroom interactionswhereateachermayresponddismissivelytoastudent squestion, produceananswertoaproblemwithlittlestudentparticipation,orbeunawareofa student sconfusioncanresultinstudentstrugglethatisunproductive.inan analysisofmathematicsclassroominstruction(weiss&pasley,2004;weiss,pasley, Smith,Banilower,&Heck,2003),only15%ofthelessonsobservedwereclassified asprovidingstudentsopportunitiesforthinking,reasoning,andsense making.

InmostU.S.middleschoolmathematicsclassrooms,onetypicallyfinds studentsengagedinamathematicslessonswithateacherexplainingaconceptor task,facilitatingaconversation,observingstudents activities,oraddressing studentswhomaybestrugglingwiththeirwork(kawanaka,stigler,&hiebert, 8

23 1999).Theseactivitiesandinteractionsarenotnecessarilymutuallyexclusive eventsandoftenoccurconcurrentlyalongwithnon mathematicalactivitiesthatadd timeandcomplexitytoclassroomroutinessuchastakingattendance,pickingup homework,orestablishingrulesandsocialnorms(kennedy,2005).whilestudents mayappeartoprogresstowardsorachievethelesson sintendedlearningobjectives withoutdifficulty,moreoftenthannot,studentsvoicetheirconfusion, misunderstanding,oracontradictionintheirthinkingandsense makingthat requirestheteachertorespond.whatisobservableinmanyclassrooms,andthus servesastheprimaryfocusofmystudy,isthisphenomenonwecallstudent struggles.mystudywillinvestigatethoseaspectsofstudentstrugglesthatbecome productiveinstudents understanding. OVERVIEWOFCONCEPTUALFRAMEWORK HiebertandGrouws(2007),intheSecondHandbookonResearchon MathematicsTeachingandLearning,usedthetermstudents struggle tomeanthat studentsexpendefforttomakesenseofmathematics,tofiguresomethingoutthatis notimmediatelyapparent (p.387).they donotusestruggletomeanneedless frustrationorextremelevelsofchallengecreatedbynonsensicaloroverlydifficult problems orthefeelingsofdespairthatsomestudentscanexperiencewhenlittle ofthematerialmakessense (p.387).thisstruggleoccursinthecontextof students solvingproblemsthatarewithinreachandgrapplingwithkey mathematicalideasthatarecomprehensiblebutnotyetwellformed (p.387).in 9

24 otherwords,struggleisaparticularkindofphenomenonthatmayoccurasstudents engageinamathematicalactivityorproblemthatischallengingbutreasonably withinthestudents capabilities,possiblywithsomeassistance.thesekindsof difficulties,namelythestrugglesthatpushthestudentsintheirthinking,canplayan importantroleindeepeningstudents understandingifdirectedcarefullytowarda resolution(hiebert&grouws,2007). Asacognitiveprocess,astudent sstruggletomakesenseofmathematicscan beviewedasinternaltothelearner.ontheotherhand,students strugglemaybe visibletoanobserverwhenstudentsexternalizethedifficultytheyareexperiencing. Theoriesoflearninghaveincorporatedbothkindsofstruggle. Otherresearchersandlearningtheoristshavearguedthataconnection existsbetweenstudentengagementinastruggletomakesenseofmathematical ideasanddeeperunderstandingoftheunderlyingconcepts(piaget,1960;dewey, 1926;Inagaki,Hatano,&Morita,1998;Stein,Grover,&Henningsen,1996).From this,iusethenotionofstruggleasacomponentofstudents engagementin mathematicalactivity.thestrugglemaytakeondifferentformsdependingonthe levelofstudentthinkingdemandedbytheactivity. Strugglemaytaketheformof:studentsarguingovercompetingclaims;or expressingtheiruncertaintyoverquestionableprocessesorconclusions(inagaki, Hatano,Morita,1998;Zaslavsky,2005;Hoffman,Breyfogle,&Dressler,2009);or simplyshuttingdowninthefaceoffrustration(dweck,1986).theseinstances 10

25 provideopportunitiesforteacherstorespondtoandsupportstudents struggles productively.researchsuggests,therefore,thatstudentsmaystrugglewith decidingwhatconceptsorprocedurestouseinsolvingaproblem,determininghow toproceedinacalculationorexplaininghowsomethingworks,orunderstanding whyaconclusionfollows.strugglemaytaketheformofstudentsvoicingconfusion inawhole classdiscussionorseekingclarificationfromtheteacherinaone on one setting(inagaki,hatano,&morita,1998;borasi,1996;santagata,2005). Myconceptualframework,therefore,isbuiltonthreemaincomponents: 1. Theroleofstruggleinlearningmathematicswithunderstanding 2. Thenatureandtypesofmathematicaltasksandtheirrelationshipto students struggle 3. Thewaysteachers respondtostudents struggleinclassroom interactions.

26 NATUREOFMATHEMATICS Overthecourseofhistory,differingperspectiveshaveresultedfromthe question:whatismathematics?theplatonists viewsuggestsmathematicsisabout discoveringtruthsandideasthatexisteternally,whiletheformalists view mathematicsasasetofrulesoraxiomsfromwhichtheoremsarelogically developed(hersh,1997).hershandothermathematiciansandmathematics educatorstakeamorehumanisticposition,viewingmathematicsasasocialactivity (Freudenthal,1991;Hersh,1997;Bass,2005).Mystudyusesthisperspectiveof mathematicsasasocialphenomenon,wherepeoplecreateobjectsandstudythe patternsandrelationshipsoftheseobjectswithinasocialculture(hersh,1997; White,1993;NCTM,2000;AAAS,1993).
