Metacognition



Concept

Amongthemanydefinitionsofmetacognition,theonemadebyFlavell,thepioneerofmetacognitiveresearch,isthemostrepresentative.In1976,heexpressedmetacognitionas"individual'sknowledgeaboutone'sowncognitiveprocessandresultsorotherrelatedthings",and"inordertocompleteaspecificgoalortask,accordingtothecognitiveobjecttoactivelycarryoutthecognitiveprocessMonitoringandcontinuousadjustmentandcoordination".In1981,hemadeamoreconcisesummaryofmetacognition:"reflectionorregulationofanyaspectofknowledgeorcognitiveactivitiesofcognitiveactivities".A.BrownandL.Bakeralsobelievethatmetacognitionis"anindividual'sknowledgeandcontrolofthecognitivedomain".Itcanbeseenthattheconceptofmetacognitionincludestwoaspects,oneisknowledgeaboutcognition,andtheotheristheregulationofcognition.Inotherwords,ontheonehand,metacognitionisaknowledgeentity,whichcontainsknowledgeaboutstaticcognitiveabilities,dynamiccognitiveactivities,etc.;ontheotherhand,metacognitionisalsoaprocess,thatis,thecurrentcognitiveactivityTheconsciousnessprocess,theadjustmentprocess.As"cognitionaboutcognition",metacognitionisconsideredtobethecoreofcognitiveactivitiesandplaysanimportantroleincognitiveactivities.
