Themeaingoflearning

Constructivismbelievesthatknowledgeisnotimpartedbyteachers,butlearnersuseotherpeople(includingteachersandlearningThehelpofpartners)isobtainedbymeansofmeaningconstructionusingthenecessarylearningmaterials.Sincelearningisaprocessofmeaningconstructionachievedthroughinterpersonalcollaborationactivitieswiththehelpofotherpeopleinacertaincontext,thatis,asocialandculturalbackground,theconstructivistlearningtheorybelievesthat“situation”,“collaboration”,“conversation”and"Senseconstruction"isthefourmajorelementsorattributesinthelearningenvironment."Context":Thecontextinthelearningenvironmentmustbeconducivetotheconstructionofthemeaningofthecontentlearnedbythestudents.Thisputsforwardnewrequirementsforinstructionaldesign.Inotherwords,inaconstructivistlearningenvironment,instructionaldesignmustnotonlyconsidertheanalysisofteachingobjectives,butalsoconsiderthecreationofsituationsthatareconducivetotheconstructionofmeaningforstudents,andlookatthecreationofsituations.Workisoneofthemostimportantcontentsofinstructionaldesign."Collaboration":Collaborationoccursthroughoutthelearningprocess.Collaborationplaysanimportantroleinthecollectionandanalysisoflearningmaterials,theformulationandverificationofhypotheses,theevaluationoflearningresults,andthefinalconstructionofmeaning."Conversation":Conversationisanindispensablepartofthecollaborationprocess.Themembersofthestudygroupmustdiscusshowtocompletetheprescribedlearningtaskplanthroughconversation;inaddition,thecollaborativelearningprocessisalsoaconversationprocess,inthisprocess,eachlearner'sthinkingresults(wisdom)aresharedbytheentirelearninggroup,soConversationisoneoftheimportantmeanstoachievemeaningconstruction."Senseconstruction":Thisistheultimategoaloftheentirelearningprocess.Themeaningtobeconstructedrefersto:thenatureandlawsofthingsandtheinternalconnectionsbetweenthings.Tohelpstudentsconstructmeaninginthelearningprocessistohelpstudentsachieveadeeperunderstandingofthenatureandlawsofthethingsreflectedinthecurrentlearningcontentandtheinternalconnectionsbetweenthethingsandotherthings.Thelong-termstorageformofthisunderstandinginthebrainistheaforementioned"schema",whichisthecognitivestructureofwhatiscurrentlybeinglearned.Fromthemeaningof"learning"mentionedabove,itcanbeseenthatthequalityoflearningisafunctionofthelearner'sabilitytoconstructmeaning,notafunctionofthelearner'sabilitytoreproducetheteacher'sthinkingprocess.Inotherwords,theamountofknowledgeacquireddependsonthelearner’sabilitytoconstructthemeaningoftheknowledgebasedonhisownexperience,ratherthanonthelearner’sabilitytomemorizeandrecitewhattheteacherteaches.

TeachingThoughts

Theteachingthoughtscontainedinconstructivismaremainlyreflectedintheviewofknowledge,theviewoflearning,theviewofstudents,thepositioningandroleofteachersandstudents,thelearningenvironmentandteachingprinciples,etc.6aspects.

KnowledgeView

(1)Knowledgeisnotapurelyobjectivereflectionofreality,norisanysymbolsystemthatconveysknowledgearepresentationofabsolutetruth.Itisjustanexplanation,hypothesisorhypothesisoftheobjectiveworldbypeople.Itisnotthefinalanswertothequestion.Itwillinevitablyundergocontinuoustransformation,sublimationandrewritingaspeople'sunderstandingdeepens,andnewexplanationsandhypotheseswillappear.

(2)Knowledgecannotsummarizethelawsoftheworldabsolutelyandaccurately,andprovidepracticalmethodsforanyactivityorproblemsolving.Inthesolutionofspecificproblems,knowledgecannotbeaccurateandeffectivewhenused.Instead,theoriginalknowledgeneedstobereprocessedandrecreatedaccordingtothesituationofthespecificproblem.

Viewonlearning

(1)Learningisnotaprocessinwhichteacherssimplytransferknowledgetostudents,butisaprocessinwhichstudentsconstructknowledgethemselves.Studentsdonotsimplyreceiveinformationpassively,butactivelyconstructthemeaningofknowledge.Thisconstructioncannotbereplacedbyothers.

(2)Learningisnottopassivelyreceiveinformationstimulation,buttoactivelyconstructmeaning.Itistoactivelyselect,processandprocessexternalinformationaccordingtoone'sownexperiencebackground,soastoobtainone'sownmeaning.Externalinformationitselfhasnomeaning.Themeaningisconstructedbylearnersthroughtherepeatedandtwo-wayinteractionprocessbetweennewandoldknowledgeandexperience.Therefore,learningisnotlikethe"stimulus?response"describedbybehaviorism.

(3)Theacquisitionoflearningmeaningisthateachlearnerre-recognizesandencodesnewinformationbasedonhisownoriginalknowledgeandexperience,andconstructshisownunderstanding.Inthisprocess,thelearner'soriginalknowledgeandexperienceareadjustedandchangedduetotheentryofnewknowledgeandexperience.

(4)Assimilationandadaptationaretwowaysorwaysthatlearners'cognitivestructurechanges.Assimilationisthequantitativechangeofcognitivestructure,whileadaptationisthequalitativechangeofcognitivestructure.Assimilation-Adaptation-Assimilation-Adaptation...cyclical,balance-imbalance-balance-imbalance,mutualalternation,thedevelopmentofhumancognitivelevel,issuchaprocess.Learningisnotasimpleaccumulationofinformation,butmoreimportantly,itcontainstheconflictbetweenoldandnewknowledgeandexperience,andthereorganizationofthecognitivestructurecausedbythis.Thelearningprocessisnotsimpleinformationinput,storageandextraction,butatwo-wayinteractionprocessbetweennewandoldknowledgeandexperience,thatis,theprocessofinteractionbetweenthelearnerandthelearningenvironment.

StudentView

(1)Constructivismemphasizesthatlearnersdonotenterthelearningsituationwiththeirheadsempty.Indailylifeandvariousformsoflearninginthepast,theyhaveformedrelevantknowledgeandexperience,andtheyhavetheirownviewsoneverything.Eveniftherearesomeproblemstheyhaveneverbeenincontactwith,andthereisnoexistingexperiencetolearnfrom,butwhentheproblemispresentedtothem,theywillstillformanexplanationoftheproblemandputforwardtheirhypothesisbasedontheirpastexperienceandrelyingontheircognitiveability..

(3)Teachersandstudents,studentsandstudentsneedtoexploresomeproblemstogether,andcommunicateandquestioneachotherintheprocessofexploration,andunderstandeachother'sideas.Duetotheinevitabledifferencesinexperiencebackground,learners'viewsandunderstandingoftheproblemareoftenvastlydifferent.Infact,inthestudentcommunity,thesedifferencesthemselvesareavaluablephenomenonresource.Althoughconstructivismattachesgreatimportancetoindividualself-development,hedoesnotdenyexternalguidance,thatis,theinfluenceofteachers.

Theorientationofteachersandstudents

(1)Theroleofteachersisaloyalsupporterofstudents'knowledgeconstruction.Theroleoftheteacherhaschangedfromthetraditionalauthorityofknowledgetransfertothetutorofstudentlearning,becomingtheseniorpartnerorcollaboratorofstudentlearning.Teachersshouldprovidestudentswithcomplexrealquestions.Notonlymusttheydevelopordiscovertheseproblems,buttheymustalsorecognizethattherearemultipleanswerstocomplexproblems,andencouragestudentstohavemultipleviewsonproblemsolving.Thisisobviouslyincloseagreementwiththepurposeofcreativeteachingactivities.Teachersmustcreateagoodlearningenvironmentinwhichstudentscanstarttheirlearningthroughexperiments,independentexploration,cooperativelearning,etc.Teachersmustensureabalancebetweenlearningactivitiesandlearningcontent.Teachersmustprovidestudentswithmetacognitivetoolsandpsychologicalmeasurementtools,cultivatestudents'criticalcognitiveprocessingstrategies,andconstructtheirownmentalmodelsofknowledgeandunderstanding.Teachersshouldrecognizethatteachinggoalsincludecognitivegoalsandemotionalgoals.Teachingisaprocessofgraduallyreducingexternalcontrolandincreasingstudents'self-controlledlearning.

(2)Ifteacherswanttobeactivehelpersandguidesforstudentstoconstructknowledge,theyshouldstimulatestudents'interestinlearning,andstimulateandmaintainstudents'learningmotivation.Bycreatingscenariosthatmeettherequirementsoftheteachingcontentandcluesthatsuggesttheconnectionbetweenthenewandtheoldknowledge,ithelpsstudentsconstructthemeaningofthecurrentknowledge.Inordertomakestudents'meaningconstructionmoreeffective,teachersshouldorganizecollaborativelearningasmuchaspossible,launchdiscussionsandexchanges,andguidethecollaborativelearningprocesstodevelopinadirectionthatisconducivetomeaningconstruction.

Studentsarethesubjectofcognitionandtheactiveconstructorofthemeaningofknowledge;teachersonlyhelpandpromotethemeaningconstructionofstudents,anddonotrequireteacherstodirectlyteachandinstillknowledgetostudents.Intheconstructivistlearningenvironment,thestatusandroleofteachersandstudentshaveundergonegreatchangescomparedwithtraditionalteaching.Expertsinthefieldofeducationaltechnologyhaveconductedalotofresearchandexploration,tryingtoestablishanewsetofteachingdesigntheoryandmethodsystemthatcanbecompatiblewiththeconstructivistlearningtheoryandtheconstructivistlearningenvironment.Althoughtheestablishmentofthistheoreticalsystemisanarduoustask,itcannotbecompletedinashortperiodoftime.However,itsbasicideasandmainprincipleshavebecomecleardaybyday,andhavebeguntobepracticallyappliedtoguidetheteachingdesignofaconstructivistlearningenvironmentbasedonmultimediaandtheInternet.Theteachingdesignprinciplesusedbyconstructivismareasfollows:

Emphasizestudent-sitas

Clarify"student-centered",whichisofgreatimportancetoteachingdesignImportantguidingsignificance,becausestartingfrom"student-centered"or"teacher-centered"willresultintwocompletelydifferentdesignresults.Asforhowtoembodystudent-centeredness,constructivismbelievesthatwecanworkhardfromthreeaspects:

Togivefullplaytotheinitiativeofstudentsinthelearningprocess,toreflecttheinitiativespiritofstudents;

Studentsshouldhavemultipleopportunitiestoapplytheirknowledgeindifferentsituations("externalizing"knowledge);Understandingofobjectivethingsandsolutionstopracticalproblems(realizingself-feedback).

Theabovethreepoints,namely,exertingthespiritofinitiative,externalizingknowledgeandrealizingself-feedbackcanbesaidtoembodythethreeelementsofstudent-centeredness.

Emphasizetheimportantroleof"context"intheconstructionofmeaning

Constructivismbelievesthatlearningisalwaysconnectedwithacertainsocialandculturalbackground,namely"context"Yes,learninginactualsituationscanenablelearnerstousetherelevantexperienceintheiroriginalcognitivestructuretoassimilateandindexthenewknowledgetheycurrentlylearn,therebygivingthenewknowledgeacertainmeaning;iftheoriginalexperiencecannotAssimilationofnewknowledgerequiresaprocessof"adaptation",thatis,thetransformationandreorganizationoftheoriginalcognitivestructure.Inshort,theconstructionofthemeaningofnewknowledgecanonlybeachievedthrough"assimilation"and"adaptation".Intraditionalclassroomteaching,becauseitcannotprovidethevividnessandrichnessoftheactualsituation,itwillmakeitdifficultforlearnerstoconstructthemeaningofknowledge.

Emphasisonthekeyroleof"collaborativelearning"intheconstructionofmeaning

Constructivismbelievesthattheinteractionbetweenlearnersandthesurroundingenvironmentandtheunderstandingoflearningcontent(Thatis,theconstructionofthemeaningofknowledge)playsakeyrole.Thisisoneofthecoreconceptsofconstructivism.Undertheorganizationandguidanceoftheteacher,thestudentsdiscussandcommunicatetogether,andjointlyestablishalearninggroupandbecomeamemberofit.Insuchagroup,jointlycriticallyexaminevarioustheories,opinions,beliefsandhypotheses;conductconsultationsanddebates,firstinternalconsultation(thatis,arguingwithoneselfwhichviewiscorrect),andthenmutualconsultation(thatis,thecurrentproblemPresenttheirownopinions,argumentsandrelatedmaterials,andanalyzeandcommentontheopinionsofothers).Throughsuchacollaborativelearningenvironment,thethinkingandwisdomofthelearnergroup(includingtheteacherandeachstudent)canbesharedbytheentiregroup,thatis,theentirelearninggroupcompletesthemeaningconstructionoftheknowledgelearned,ratherthanoneofthem.Oneorseveralstudentscompletemeaningconstruction.

Emphasisonthedesignofthelearningenvironment

(ratherthantheteachingenvironment)

ConstructivismbelievesthatthelearningenvironmentissomethingthatlearnerscanAplaceforfreeexplorationandindependentlearning.Inthisenvironment,studentscanusevarioustoolsandinformationresources(suchastextmaterials,books,audio-visualmaterials,CAIandmultimediacourseware,andinformationontheInternet,etc.)toachievetheirlearninggoals.Inthisprocess,studentscannotonlygethelpandsupportfromteachers,butalsocollaborationandsupportamongstudents.Learningshouldbepromotedandsupportedratherthanstrictlycontrolledanddominated;thelearningenvironmentisaplacetosupportandpromotelearning.Theinstructionaldesignguidedbytheconstructivistlearningtheoryshouldbeaimedatthedesignofthelearningenvironmentratherthanthedesignoftheteachingenvironment.Becauseteachingmeansmorecontrolanddominance,andlearningmeansmoreinitiativeandfreedom.

Emphasizetheuseofvariousinformationresourcestosupport"learning"

(insteadofsupporting"docere")

InordertosupportlearningThelearner’sactiveexplorationandcompletionofmeaningconstructionmustprovidelearnerswithvariousinformationresources(includingvarioustypesofteachingmediaandteachingmaterials)duringthelearningprocess.Theuseofthesemediaandmaterialshereisnottoassistteachers'explanationsandpresentations,buttosupportstudents'autonomouslearningandcollaborativeexploration.Howtoobtaininformationresources,wheretoobtainthem,andhowtousethemeffectivelyarethecontentthaturgentlyneedshelpfromteachersintheprocessofactiveexploration.

Emphasizethattheultimategoalofthelearningprocessistocompletemeaningconstruction

(Nottocompletetheteachinggoal)

IntheconstructivistlearningenvironmentItemphasizesthatstudentsarecognitivesubjectsandactivebuildersofmeaning,sotheconstructionofstudents'meaningofknowledgeistheultimategoaloftheentirelearningprocess.Instructionaldesignusuallystartsnotfromanalyzingtheteachinggoals,butfromhowtocreateacontextthatisconducivetotheconstructionofmeaningforstudents.Theentireteachingdesignprocessiscloselyfocusedonthecenterof"meaningconstruction",whetheritisstudents’independentexploration,collaborativelearningorTeacherguidance,inshort,allactivitiesinthelearningprocessmustbesubordinatetothiscenter,andmustbeconducivetocompletinganddeepeningthemeaningconstructionoftheknowledgelearned.
