1.Nodes

Itisthebasicunitofstoringinformation,alsoknownasinformationblock.Eachnodeexpressesaspecifictopic,anditssizedependsonactualneeds.Therearenostrictrestrictionsonwriting.

(1)Textnodescanbeusedtoexpressideas,explainconcepts,describephenomena,etc.

(2)Graphicnodesaresuitableforexpressingtheshapeandstructureofthings.

(3)Auditorynodes

(4)Audiovisualnodes

(5)Programnodesareusuallyrepresentedby"buttons",enterthisAfterthenode,thecorrespondingprogramwillbestartedtocompletethespecificoperation.

Second,thelink(Link)

Thelinkrepresentstheconnectionofinformationbetweendifferentnodes.Itisfromanodetoothernodes,orfromothernodestothenode.Becausetheconnectionbetweeninformationisever-changingandcolorful,thechainisalsocomplexanddiverse,includingone-waychain(→),two-waychain(←→)andsoon.Thestrengthofthefunctionofthechaindirectlyaffectstheexpressivenessofthenode,andalsoaffectsthestructureoftheinformationnetworkandtheabilityofnavigation.Onlywhenthereisachaininhypertextcantherebenonlinearity;onlywhenthereisachain,userscanfindrelevantinformation"along"thechain.Inmultimediacourseware,thechainishiddenbehindtheinformationandrecordedinthesystem.Wecan'tseetheone-wayortwo-waylines,butwhenwemovefromonenodetoanother,wewillfeeltheexistenceofthechain.

Thebasiccombinationsofchainsareasfollows:

(1)Alinearbrowsingpath

(2)Treestructure

(3)Alooplessnetwork

(4)Blockconnection

(5)Anyconnection

3.Network

Theinformationnetworkofhypertextisadirectedgraphstructure,whichissimilartotheassociativememorystructureofthehumanbrain.Itusesanon-linearnetworkstructuretoorganizeblockinformation.Theconnectionofinformationinthehypertextnetworkreflectstheteachingintentionsandstrategiesofthecoursewarecreators.Thehypertextnetworkstructurenotonlyprovidesknowledgeandinformation,butalsoincludestheauthor'sanalysis,reasoningandintegrationofinformation.

Iftherearenotonlytextsinthenodesinthenetwork,butalsographics,animations,soundsandtheircombinationsandotherinformation,thatis,hypertexttechnologyisusedtomanagemultimediainformation,thiskindofsystemiscalledHypermedia.

2.4Structuraldesign

Thestructuraldesignofmultimediacoursewaremainlyincludesthefollowingaspects:nodedesign,chaindesign,andtheresultingnetworkandlearningpathdesign.

1.Nodedesign

Therootnodeisthefirstnodethatlearnersencounterwhentheyenterthesystemtolearn,anditisalsothecentralnodethatanyothernodecanreturn.Therefore,therootnodeDesignisveryimportant.Thecommonlyuseddesignmethodsoftherootnodeare:

(1)OverviewTherootnodeisanoverviewoftheentirecontent,anditisconnectedwithallthemainconceptsintheknowledgebase.

(2)FromtoptobottomUsingtheanalytichierarchyprocess,therootnodeisthemainessentialconceptatthetop.

(3)MenuTherootnodeisalistorcontenttableofthemainconceptsintheknowledgebase.

(4)TutoringTherootnodeisademonstrationofenteringthechannelofothernodes.

Second,thedesignofthechain

Thedesignofthechainmainlyinvolveshowthenodesareconnectedandhowtheyarerepresented.

Chainsaredividedintothreetypes:

Linearchainsreflecttheorder,positionandotherrelationsbetweennodes.

Thetree-shapedchainreflectsthehierarchical,attribution,andanalogyrelationshipsamongnodes,andreflectsthesemanticandlogicalconnectionofnodecontent.

Meshchain,thatis,anynodecanestablishaconnection,suchasbackground,index,illustration,keypoint,referencematerial,etc.,reflectingtheassociationofcreators.Theproportionofvarioustypesofchainsinahypermediasystemdependsondomainknowledge,systempurposeandlearningcharacteristics.

3.Networkandlearningpathdesign

Theorganizationofnodesandchainsisdifferent,resultingindifferentnetworkstructuresofhypermediasystems:hierarchical,detailed,anddialogue.

Commonlearningpathmodesare:sequential,circular,branch,index,andmesh.
