LEARNINGFROMINSTRUCTION:

PROFILESOFCLASSROOMEXPERIENCESUSINGSTANDARDS-BASEDANDTRADITIONALCURRICULA

Purpose

Theultimategoalofeducationalresearch,curriculumdevelopment,andinstructionalimprovementistoenhancestudentlearning.Historically,curriculahavebeenusednotonlytocommunicatewhatstudentsshouldlearn(NCTM,1989),butalsotoguideinstruction(Ball&Cohen,1996).Accordingly,manyadvocatesofmathematicseducationreformbelievethatchangingthecurriculumisaneffectivewaytoimproveclassroompracticeandenhancestudentlearning(NCTM,1989,2000;Howson,Keitel,&Kilpatrick,1981;Senk&Thompson,2003).However,itisbynomeanscertainthatthecurriculumassignedtoateachersignificantlyinfluencesthatteacher’sclassroominstruction,letaloneinfluenceitinwaysthattheauthorsintended(Ball&Cohen,1996;Fullan&Pomfret,1977).Therefore,importantquestionswithregardtocurriculaarewhether,how,andtowhatextenttheyinfluencetheinstructionoftheteacherswhousethem.Thepurposeofthisstudyistoshedlightonthosequestionsbyconstructinginstructionalprofilesofteacherswhouseoneortheotheroftwotypesofmiddleschoolmathematicscurricula:

Standards-basedortraditional.

BackgroundandTheoreticalConsiderations

Standards-BasedMathematicsCurricula

Inthelate1980sandearly1990s,theNationalCouncilofTeachersofMathematics(NCTM)publisheditsfirstroundofStandardsdocuments(e.g.NCTM,1989,1991,1995),whichprovidedrecommendationsforreformingandimprovingK-12schoolmathematics.IntheStandardsandrelateddocumentsthatappeared,thediscussionsofgoalsformathematicseducationemphasizetheimportanceofthinking,understanding,reasoning,andproblemsolving,withanemphasisonrepresentations,connections,applications,andcommunication.Thisviewstandsincontrasttoamoreconventionalviewofthegoalsformathematicseducation,whichemphasizesthememorizationandrecitationofdecontextualizedfacts,rules,andprocedures,withthesubsequentapplicationofwell-rehearsedprocedurestosolveroutineproblems.

Inthe1990s,theNationalScienceFoundationprovidedextensivefundingtodevelopandimplementanumberofStandards-basedschoolmathematicscurriculathatalignwiththerecommendationsintheStandards(Senk&Thompson,2003;NationalResearchCouncil,2004).TheresultingNSFcurriculausetheexplorationofreal-lifeproblemsasawaytostrengthenstudents’understandingofimportantmathematics.TheimplementationoftheseStandards-basedcurricularequiresthatteacherschangethewaytheyhavetraditionallytaughtmathematicsandthatstudentschangetheirviewsofwhatlearningmathematicsentails.Unfortunatelyforthereformmovement,teachersfacechallengeswhentryingtoimplementtheseinnovativecurricula.EveninclassroomswhereteachersattempttoteachforunderstandingasspecifiedbytheNCTMStandards,teachersoftenmaintainmanyexistingmathematicspracticesinconsistentwiththerecommendationsspecifiedintheNCTMStandards(Hiebert&Stigler,2000;Spillane&Zeuli,1999;Rand,2002;Gross&Merchlinsky,2002).

Ontheonehand,NSF-fundedcurriculaarereferredtoasStandards-basedbecausetheywerefundedspecificallytosupportStandards-basedinstructionandbecausetheytypicallybuildstudents’understandingofimportantmathematicsthroughexplorationsofreal-worldsituationsandproblems.Ontheotherhand,mostpublishersofso-calledtraditionalcurriculaalsoclaimthattheircurricularmaterialsareStandards-based.Infact,theirteachers’guidestypicallydescribehowthechapters,ifnotthelessonsineachchapter,correspondtotheNCTMcontentandprocessstandards(e.g.,Baileyetal.,2006a,2006b,2006c).Nonetheless,unliketheNSF-fundedcurricula,thesecurriculaarecommonlyreferredtoas“traditional”ratherthan“Standards-based”(Nie,Cai,Moyer,inpress).Inkeepingwiththiscommonpractice,werefertotheNSF-fundedandtheothercurriculadiscussedinthispaperas“Standards-based”and“traditional,”respectively.

Standards-BasedCurriculumResearch

Giventhedisparitybetweenthebeliefsofreformadvocatesandreformopponents,researchontheeffectivenessofstandards-basedcurriculahasbeenongoingsincethe1990s(e.g.,Carroll,1997;McCaffreyetal.,2001;Riordan&Noyce,2001;Ridwayetal.,2003;Schoenetal.,2003;Tarr,etal.,2008).Classroominstructionisconsideredacentralcomponentinthedevelopmentandtheorganizationofstudents'thinkingandlearning(Detterman,1993;Rogoff&Chavajay,1995;Wozniak&Fischer,1993).However,muchoftheresearchthathasstudiedtheeffectivenessofreformcurriculaonstudentachievementdidnotinvestigatethetypeofinstructionalexperiencesthatteachersprovidewhenimplementingStandards-basedcurricula.

Ridgwayetal.(2003)conductedthreestudiesoftheeffectivenessoftheConnectedMathematicsProgram(CMP),oneoftheStandards-basedmiddleschoolcurricula.Ofallthevariablesinthelarge-scalestudydatabase(includingteacher,class,school,site,gender,andfalltestachievementlevels),theonlyoneassociatedwithgainsinattainmentwascurriculum.Howevernoneofthethreestudiesincludedin-depthinformationabouthowCMPwasactuallyusedintheschools.Ridgway,etal.concludedthatthereisaneedtodocumentthenatureofinstructionoccurringintheclassroomswherereformcurriculaarebeingimplemented.

AstudybySchoenetal.(2003)didjustthat.Theyexaminedtherelatednessofstudentachievementtotheinstructionalpracticesof40highschoolteacherswhowereusingaStandards-basedcurriculum(Coxfordetal.,2003).Schoen,etal.conductedclassroomobservationsofeachteacherduringthecourseofaschoolyear;theyalsoadministeredtwoinstruction-relatedself-reportsurveystotheteachers.Resultsshowedthattheimplementationofcognitivelydemandingtasksforstudentsandadherencetoreformprinciplesduringinstructionweresignificantlyandpositivelyassociatedwithstudentachievement.Incontrast,resultsalsoshowedthatthepercentagesofclasstimespentonbothteacherpresentationsandwholeclassdiscussionswerenegativelyassociatedwithstudentachievement.Inamorerecentstudy,Tarretal.(2008)showedthattheinteractionofcurriculumwithastandards-basedlearningenvironmentinthemiddlegradeswasassociatedwithasignificantimpactonstudentachievement.

BecauseNSF-fundedcurriculalikeCMPclaimtohavedifferentlearninggoalsthantraditionalcurricula,andbecausethelayoutandorganizationofreformtextsistypicallyquitedifferentthantraditionalmathematicstexts,naturalquestionstoaskare:

DoesinstructionusingaStandards-basedcurriculumreallydifferfrominstructionusingatraditionalcurriculum?

Ifso,whataretheimportantfeaturesofinstructionusinganNSF-fundedStandards-basedcurriculumthatdistinguishitfrominstructionusingso-calledtraditionalcurricula?

InwhatwaysdoesaStandards-basedcurriculumlikeCMPinfluenceinstructionthataredifferentfromthewaysthatmoretraditionalmiddleschoolcurriculainfluenceinstruction?

Toanswerquestionslikethese,researchersneedtoinvestigatethewayteachersteachStandards-basedandtraditionalcurricula(Kilpatrick,2003,NRC,2004,Wilson&Floden,2001).Indoingso,researchersmustattendtothoseaspectsofteachingthathavepotentialtoinfluencestudents’learningopportunities.ThepurposeofthispaperistoidentifyandcomparetheinfluentialdistinguishingfeaturesofinstructionusinganNSF-fundedcurriculumwiththeinfluentialdistinguishingfeaturesofinstructionusingatraditionallybasedcurriculum.
