Toputitinanotherway,theoperational(working)philosophiesthatdriveourbelief systemsandconsequentlyourbehavioursdonotarisefromindependentthinkingbutfromthe wayinwhichweinteractwithotherpersons[1].Indeed,asthephilosopherJohnMacmurray concludedthatwecometoknowwhoweareasindividualsonlyinpersonalrelationships[2].But wedomakedecisionsanditisinthemakingofthedecisionsthatwebegintheactoflearning. Forthemostpart,mostofusdonotquestiontheoperationalphilosophiesorbeliefsystemsthat driveourlearning.Inanycase,forthemostpart,theyareimplicitlyheld.Consider,forexample, howourphilosophyofengineering,thatis,whatwebelieveengineeringtobe,wasformed.Was itsimplyaformofappliedscienceorsomethingmore?Thenconsider,ifafterexperiencein industry,thisviewhaschanged.Now,ifweareconsideringteachingorareteaching,shouldwe spendsometimeconsideringwhatengineeringis?Thevolumesinthisseriesareintendedto presentthereaderwiththischallenge.
Itisarguedthateveryengineeringeducatorshouldhaveathoughtoutviewofwhatengineeringis,becausewhathappensinengineeringshoulddictateinnosmallwaytheprocessofthe curriculum,itsgoals,andthemeansofachievingthem.Bycurriculum,itmeansalltheformal andinformalfactors(e.g.,organizationalstructure,peers,tutorialarrangements)thatinfluence themotivationtolearn[3–6].
Manyargue,asdoWilliamGrimsonandJerryGravanderinChapters 2 and 3,thataphilosophyofengineeringeducationthatunderpinswhatwedoinpracticeisnotpossiblewithout firstdevelopingouroperationalphilosophiesofengineeringbeyondtheimplicittosomething substantialandexplicit.Andthat,arguesWilliamGrimsoninChapter 2,maybeachievedby anunderstandingofthe“isms”ofphilosophyastheyhavedevelopedfromAristotleandPlato onwards.Toputitinanotherway,engineersneedtounderstandwhotheyareiftheyareto provideacurriculumthatistoservetheneedsofengineering.Thatthisisimportantisevident fromthelargevolumeofliteraturethathasemergedonthedifferencesbetweenengineering andscience[7],atopicthatisconsideredbyGregoryBassettandJohnKrupczakinChapter 4.
Theleastthatcanbesaidisthatbydefinitionanengineerisachangeagent.Itfollows thattheresultsofwhatengineersdowillnecessarilyrequirechangesinthecurriculum.Yetithas proveddifficulttodoand,therefore,thegoalsthatmanyengineersandengineeringeducators thinkdesirablehavenotbeenobtained[8].Astrongcasehasbeenmadethatthereasonforthis
1.2. BEYONDOPERATIONAL(WORKING)PHILOSOPHY3 is thatengineeringeducatorshavelackedaproperphilosophicalbasethatwouldprovidethe guidelinesrequired[9].
Analternativepositionarisesfromtheviewthatsinceengineeringeducationissimplythe applicationofscience(mainlyphysics)tothesolutionofpracticalproblems,itsphilosophical basesaretobefoundinthephilosophyofscienceeducationforwhichasignificantliterature exists,e.g.,[10, 11].Indeedmanyscienceandengineeringeducatorsarecommittedtoaconstructivistperspectiveoflearningaboutwhichmuchhasbeenwritteninscience[12].Yet,whilst thereisastrongcaseforexaminingthatliteraturewithrespecttoteachingtheappliedsciences, thereisanequallysubstantialliteraturethatshowsthatengineeringissomethingmorethan theapplicationofsciencetothesolutionofproblems,notleastinthewaydesignsareborn, developed,andimplementedasBassettandKrupczakshowinChapter 4.Theyechotheview expressedinseveralsubstantivetextsthatengineeringisadifferentwayofthinkingtothatof thescientist[13, 14].GravanderisadamantinChapter 3 thatphilosophyofengineeringisnot philosophyofscience.
Withinthepracticeofengineering,differentphilosophiesleadtodifferentperspectiveson ethicalissues[15]thathaveamajorbearingonthecurriculumofferedtostudents.Forexample, “realists”takea“correspondence”theoryoftruth;thatis,astatementistrueifitcorrespondstoa stateofaffairsindependentofthestatement.Incontrast,constructivistswhoarealsorelativists (theyneednotberelativists)takea“coherence”theoryoftruth;thatis,astatementistrueif itcoheresorfitswithotherstatementsthataretrue.“Truth,theywillclaim,isconstructedby humanbeingswithinthesocietiesinwhichtheylive.Inmorality,therefore,thereisnosearch foranyrealitybeyondthemoralruleshumanbeingscreateandliveby”[16].Realists,onthe otherhand,arguethatthereisonlyonesetoftruthsandthatthetaskofmoralphilosophyisthe searchforthosetruths.Todefendamoralpositiononehastobesureaboutthebasisofone’s beliefs;thatis,theyhavetobedefensible.
Exactlythesameappliestoreasoningabouteducationalissueswhichoftendoesnotextend muchbeyondthetrivialwhencomparedtotheknowledgethatisavailable.Therecentdebate abouttheproposedrevisionoftheABETcriteriafallsintothiscategory,andillustratesthefailureoftheengineeringfraternitytohaveafundamentaldebateabouttheaimsofengineering educationthatisotherthanasetofwarringopinions.Butiftheparticipantsinanydebatehave notunderstoodthephilosophicalbasisoftheiropinionsthatistobeexpected.Priorknowledge isaprerequisitetounderstandinganyissueincludingknowledgeofone’sownassumptionsand predispositions.Hencetheneedforengineeringeducatorstohaveanarticulatedanddefensiblephilosophyofeducationwhendiscussingthegoals,content,andpedagogyofengineering education.Itisnecessary,therefore,thatinprovidingthebaseforaphilosophyofengineeringeducationitisinformedbyphilosophiesofeducation.Thesepointswillbeillustratedby referencetothedebateaboutABET’sproposalstochangetheircriteria.
1.3THEABETDEBATE
Twodimensionsofthisdebatewillbeconsidered.Thefirst,forwantofabetterterm,iscalled “technical.”Itisaboutthedesignofthecriteriaandneedtoattendto“meaning.”Itjustifies attentiontothepreceptsofanalyticphilosophyandthemeaningofstatements.Thesecond dimensionmightbestbedescribedbytheterm“philosophical.”Itseekstounderstandthebelief systemsthatdrivethecurriculumdebate,foritisaboutwhatcontentthenewregulationsallow andwhatcontenttheydonot.
1.4THETECHNICALDIMENSION:LANGUAGEAND THEMEANINGOFTHINGS
Althoughtheaveragememberofthepublic,andforthemostpartthatisyouandI,would notwanttoengageintheabstractconversationsofphilosophersonlanguage,somethingshave trickleddownintothepublicarena.Forexample,theanalyticphilosophersofthe20thcentury havemadeusincreasinglyawareoftheneedtoclarifymeaning:weknowthatifthequestions wesetinapublicexaminationareunclearthereisthepossibilitythatwewillbetakentocourt. Morepertinently,weknowthatifaninstructionwegivetoatechnicianismisunderstood,and leadstoanaccident,thatweareultimatelyresponsibleforwhathappened.Soweneedtocheck thatourinstructionsareunderstoodandnotmisunderstood.
Nowheredoestheproblemofmeaningraiseitsuglyheadmorethanintheinterpretation ofstatistics,particularlythosetobefoundinnewspapers,e.g.,onforecastsofthestateofthe economy.Sincetheyear2000,engineeringeducatorsintheU.S.havebeenrequiredbyABET toensurethattheprogramstheyteachwillachievecertainspecifiedoutcomes.Beforetheywere introducedintheyear2000,engineeringeducatorswereabletoattendmeetingsthatclarified themeaningoftheseoutcomes.Twoengineeringeducators,YokomotoandBostwick,argued that“secondarymeaningsofsomewordsaresometimesused,suchasusingtheterm‘criteria’ todescribethelevelofperformancethatstudentsmustachieveand‘outcomes’todescribethe learningbehavioursstudentsmustdemonstrate”[17].Amorecommondefinitionof“outcome” is“result”or“consequence,”andanyoneattachingthatmeaningtothewordwillsurelybecome confusedinanydiscussionaboutwritingmeasurableoutcomes.YokomotoandBostwicksaid thattheaimslistedbyABETwereconsideredtobetoobroadtobeassesseddirectly,andinthe traditionof TheTaxonomyofEducationalObjectives theyrecommendedthatthoseaimsshould bebrokendownintosmaller,moremeasurableunits[18].Theessenceoftheirargumentwas thataccreditingagenciesshouldexplainthetermsused,andusethemconsistently,andtothis endtheymadeadistinctionbetweencourseoutcomesandcourseinstructionalobjectives.Again, suchdistinctionsaredebatable.
Moregenerally,animportantaspectoflanguageisitsuseintheexpressionoftheemotions.Oneeffectoftheoutcomesmovementisthatithasremovedmanywordsfromthelanguageoftheacademiccommonroom.Onetermthathasmanymeaningsandisnoteasyto

1.5FROMTHEOUTSIDELOOKINGIN
WhileABETisanAmericanorganization,inrecentyearsitsinfluencehasextendedbeyondits bordersandsomecountriesareusingitsaccreditationmechanisms.Thereis,therefore,internationalinterestinthebasisoftheaccreditationcriteriawhichisthejustificationforanoutsider likeme,eventhoughIamamemberofASEEusingABET,toexemplifythecentralthesis ofthischapter,namelythateveryteachershouldhaveadefensiblephilosophyofeducation. Forthisreason,anAmericanparadigmdevelopedbyMichaelSchiro[19]whichreflectsdevelopmentsinschooleducationintheU.S.,andthephilosophiesthathavedriventhem,isused asafocusfortheargument.Schirodistinguishesbetweenscholaracademic,socialefficiency, learner-centred,andsocialreconstructionideologies.IarguethattheABETdebate,asIwas abletoobserveit,wasaconflictbetweendifferentideologies.
1.6IDEOLOGIESBEHINDTHEDEBATE
(1) Thescholaracademicideology—JohnEggleston,anEnglisheducationalsociologistand technicaleducator,hasdescribeda“received”paradigmofthecurriculumwhichhelpsto introduceSchiro’sscholaracademicideology[20].Knowledgeinthiscurriculumparadigm isreceivedandacceptedasgiven.Itisnon-negotiable,non-dialectic,andconsensual. Knowledgeissomethingthatisgivenand,consequently,isthatwhichshouldbetransmittedtostudents.Throughittheaccumulatedwisdomofacultureistransmitted.Eggleston’s paradigmissimilartothe“scholaracademicideology”proposedbySchiro.“Scholaracademics”writesSchiro,“assumethattheacademicdisciplines,theworldoftheintellect,and theworldofknowledgearelooselyequivalent.Thecentraltaskofeducationistakentobe theextensionofthecomponentsofthisequivalence,bothontheculturallevelasreflected inthediscoveryofnewtruth,andontheindividuallevel,asreflectedintheenculturation ofindividualsintocivilization’saccumulatedknowledgeandwaysofknowing”[21].
JeromeBruner,adistinguishedAmericanpsychologist,wrote:“Abodyofknowledgeenshrinedinauniversityfacultyandembodiedinaseriesofauthoritativevolumesisthe resultofmuchpriorintellectualactivity.Toinstructsomeoneinthesedisciplinesisnota matterofgettinghimtocommitresultstomind.Ratheritistoteachhimtoparticipate intheprocessthatmakespossibletheestablishmentofknowledge.Weteachasubjectnot toproducelittlelivinglibrariesonthatsubject,butrathertogetastudenttothinkmathematicallyforhimself,toconsidermattersashistoriandoes,totakepartintheprocessof knowledge-getting.Knowingisaprocess,notaproduct”[22].
1.PHILOSOPHYANDENGINEERINGEDUCATION
Theprocessthatmakespossibletheestablishmentofknowledgeis,inthisideology,what isunderstoodbylearning.Foreachschoolsubjecttheremustbeacorrespondingacademic disciplineasrepresentedintheuniversities.Becausethedisciplinesaredynamictheyare concernedasmuchwith“whatwillbe”aswith“whatwas”[23].Thatthisisso,isillustrated bythegreatcurriculumprojectsthatwereundertakeninthe1960sand1970sbecausein theU.S.teachersdidnothavetheresourcestoundertakesuchdevelopmentswhichnormallyareconsideredtobepartoftheroleoftheteacherfunctioninginthisideology[24].
Thescholaracademicideologyisteachercentred.Informationisconveyedtothemind whichreasonsaboutit,asrequired.Learningistheresultofteaching[25].Becauseeach disciplinehaswithinit,itsowntheoryoflearning,generalizedtheoriesoflearninghave noplaceinthedesignofinstruction.Itisnotunreasonabletosuggestthatthemajority ofengineeringeducatorswouldholdthisideologytobetrue.However,theyhavehad toacceptmodificationstomeettherequirementsofaccreditationauthorities,sometimes promptedbypoliticianswhoaremotivatedbythe“socialefficiencyideology.”
(2) Thesocialefficiencyideology requiresthatthecurriculumservesutilitarianpurposes, namelythecreationofwealth.Institutionshavetoberunlikebusinesses:therefore,the curriculumhastobeseentobeprovidingmeasurableoutcomesintheformofobjectivesnowcalledoutcomes.Inthisparadigmtheteacher’sroleistoguide(manage,direct, andsupervise)thelearnertoachievetheoutcomes(orterminalperformances)required. Knowledgeisdefinedbehaviourallyintermsofwhatastudent“willbeabletodo,”asa resultoflearning.Thereislittleconcernforthestudentexceptforthepotentialtheyhave asgraduates,andtheinputstheygivetotheeconomy.
Evaluationandassessmentarecentraltothevisonofthisideology.Itistheprevailing curriculumideologyinengineeringeducation,asseenforexampleinthecurrentABET criteria.Thesocialefficiencyideologyhasitsoriginsintheobjectivesmovementandthe curriculummodelofRalphTyler[26].But,Schiroalsoconsidersthateducatorswhosubscribetothisideologyvalueaprogrammedcurriculum,andthepsychologyunderpinning ittobefoundinbehaviouralpsychology,asforexamplethatofB.F.Skinner.Inengineeringeducationitcanbeseeninthesystemsofmasterylearningandpersonalisedinstruction thatwereexperimentedwithinthe1960sand1970s[27–29].
Whilebehaviouralpsychologywasreplacedbycognitivepsychologyitisrelevanttonote thattherearemanypoliticiansandadministratorswhobelievethatcomputer-assisted learningmightcometobeusedtoreplacelectureswhichtheyconsideredtobeconveyors ofthesameknowledgethatistobefoundintextbooks.Evaluationisveryimportantto thosewhoholdthisideology.Therearetensionsbetweenthosewhoadheretothescholar academicideologyaswellasthosewhoadheretothelearning-centredandsocialreconstructionideologiesandthesocialefficiencyideology.
1.6. IDEOLOGIESBEHINDTHEDEBATE7 (3) The learning-centredideology isinstarkcontrasttothesocialefficiencyideology.The childisatthecentreof,andhasaprofoundinfluenceon,thecurriculumprocess.This ideologyisassociatedwiththeeducationalphilosophyofJohnDewey.Amajorfeatureof hisapproachisinquirybasedlearning(seeChapter2byManiMinainVolume2ofthis series)Learning-centredschoolsliketheMontessorischoolswillorganizedinatotally differentwaytotraditionalschools.
Learner-centredschoolsarebasedonnaturaldevelopmentalgrowthratherthanondemandsexternaltothem.“Individualsgrowandlearnintellectually,socially,emotionally andphysicallyintheirownuniqueandidiosyncraticwaysandattheirownindividualrates ratherthanatauniformmanner”[19,p.111].Thephilosophythatunderpinstheseschools isconstructivism.Theschoolsandcurriculumaredesignedtoproducestudentswhoare “self-activatedmakersofmeaning,asactivelyself-propelledagentsoftheirowngrowth, andnotaspassiveorganismstobefilledormouldedbyagentsoutsidethemselves”[30]. Learningmovesfromtheconcretetotheabstract.Theideaofactivelearninghasbecome partofthevocabularyofhighereducation,notasyetinthesenseoforganizinganinstitutionforactivelearning,butinthesenseofteachersorganizingandmanagingtheir classroomssuchlearning.Therelationshipbetweentheteacherandthestudentisquite differenttothosebetweenstudentsandeducatorswhofollowthescholaracademicor socialefficiencyideologies,andCowan[31]argues,tobepreferred.
Insum,thecorethesesofconstructivismare:
1.Knowledgeisactivelyconstructedbythecognizingsubjectnotpassivelyreceived fromtheenvironment.
2.Comingtoknowisanadaptiveprocessthatorganizesone’sexperientialworld;it doesnotdiscoveranindependent,pre-existingworldoutsideofthemindofthe knower[32].
Thelaboratoryhasbeenfoundtobeagoodplacetoapplyconstructivistprinciplesin engineering[33].Theprojectmethodseemstohavebeenfirstintroducedtheseschools (seeChapter2byManiMinainVolume2ofthisseries).Problem-basedlearningwas practicedinmedicinefirst,andthenengineeringisinthetraditionofthisideology[34].
Theideaofnegotiatingthecurriculumhasitsoriginsintheconstructivistapproach[35]. Giventhattherealitywehaveistheresultofourenvironmentthen,inthesecircumstances, thestudentswiththeirteachersshoulddesignacurriculumthatisrealtothem.Inthis sense,thecurriculumshouldbenegotiableandworkedouttosuittheindividualneedsof students.Thisistheprinciplebehindthe“independentstudydegrees”thathavebeenofferedintheUK[36].InanEngineeringScienceUniversityentry-levelexaminationinthe UK,studentsnegotiatedtheprojectstheywererequiredtoundertakewiththeirteachers andtheexaminers[37].Akeyfeatureofinquiry-basedlearningand,therefore,ofproject

workistheneedtoreflectonwhathasbeenachieved.Educatorsinhighereducationhave takenonboardtheideaoflearninghowtolearnormetacognitionasunderstandinghow welearnisnowcalled.
Inadditiontoestablishingtheenvironmentforlearning,theteacherhasthefunctions ofobservinganddiagnosingindividualneedsandinterests,andfacilitatingthegrowth ofthestudentsintheircare.Learning-centrededucatorsareopposedtothepsychometric testingarequiredbysocialefficiencyeducators.Standardizedtestsareanathematolearnercentrededucators.Itisbelievedthatstudents’workshouldbeassessedbythestudents themselvesthroughlearninglogsandjournals(portfolios).Someengineeringeducators areadvocatesofpeerandselfassessmentaswellastheuseofportfoliosandjournals[38–41].
Becauseknowledgeiscreatedbyindividualsastheyinteractwiththeirenvironment,the objectivesofalearner-centrededucationarestatementsoftheexperiencesthestudent shouldhave.Thisviewbringslearner-centrededucatorsintoconflictwiththoseeducatorsandadministratorswhobelievethattheobjectivesofaneducationareitsmeasurable outcomeswhichisthecasewithABETandothersystemswhereadministratorsandpoliticiansrequiremeasuresofefficiency.
Manyengineeringeducatorsareinfluencedbytheconstructivistapproach.Atthesame time,Matthewshaspointedoutthattheconstructivistapproachtoteachingisnotunique. Manyeducatorsactivelyengagestudentsinlearninganddonotrequireaparticularepistemologytosupporttheirendeavours;andsomewouldfollowthestepsdescribedbyDriver andOldham[43]orthesimilarinquiry-basedlearningdescribedbyDewey.However, thepointisnottobecriticaloftheorybuttoacknowledgethatonthebasisoftheory, goodpracticeinteachinghasbeendeveloped.Thereisnopointinarguingthatteachers shouldhaveadefensibletheoryoflearningifitistobejudgedbytheory,andnotbythe practicaloutcomesitcauses.Moreover,itisnotanexcusefordiscontinuingthedebateor examiningouroperationalphilosophiesoflearningwithaviewtoimprovingthem.
(4) Thesocialreconstructionideology takestheviewthat,sincesocietyisdoomedbecause itsinstitutionsareincapableofsolvingthesocialproblemswithwhichitisfaced,education isconcernedwithreconstructingsociety.Philosophicallythisideologyhasitsfoundations inJohnDewey’s ReconstructioninPhilosophy and DemocracyandEducation [44, 45].AccordingtoSchirothesocialreconstructionideologywasbroughttolifethroughasplitin theProgressiveEducationAssociation[46].Asmightbeexpectedittookasocialconstructivistviewofknowledgeinwhichknowledgeisrelative.Thepurposeofteachingis tostimulatestudentstoreconstructthemselvessothattheycanhelpreconstructsociety. Someauthorsseeteachingasasubversiveactivity[47].
Theprinciplemethodsofteachingarethe“discussion”and“experience”groupmethods. Inthe“discussion”methodtheteacherelicits“fromthestudentsmeaningsthattheyhave
1.6. IDEOLOGIESBEHINDTHEDEBATE9 alreadystoredupsothattheymaysubjectthosemeaningstoatestingandverifying,reorderingreclassifying,modifyingandextendingprocess”(PostmanandWeingartnercited bySchiro[48]).Inthisway,atransformationofandreconstructionofknowledgeoccurs inresponsetothegroupprocess.Theexperiencemethodplaces“thestudentsinanenvironmentwheretheyencounterasocialcrisisandlearnfromthosewhousuallyfunctionin thatenvironment”[49].Theteacherinthistechniquebecomescolleagueandfriend.
Schirowrites“humanexperience,educationtruthandknowledgearesociallydefined.Humanexperienceisbelievedtobefundamentallyshapedbyculturalfactors;meaningin people’slivesisdefinedintermsoftheirrelationshiptosociety.Educationisviewedasa functionofthesocietythatsupportsitandisdefinedinthecontextofaparticularculture. Truthandknowledgearedefinedbyculturalassumptions:theyareidiosyncratictoeach societyandtestableaccordingtocriteriabasedinsocialconsensusratherthanempiricism orlogic”[50].
Whiletheviewofthosewhoholdtothisideologymayseemwayoutsidethescopeof engineeringeducation,isit?Clearlytheanswerisyes.Forexample,someengineering educatorshavepromotedthecauseofpeaceengineering[51],andotherssocialjustice[52]. LangdonWinnerarguesthatsomethegrandventuresthatengineersengageinhaveantidemocraticimplicationswhichneedtobethoughtaboutbeforetheyundertakethem[53]. Hearguesthatethicseducationmustpreparestudentsforthepoliticaltaskstheywill undoubtedlyfaceasprofessionals[54].
Itisunlikelythatmanyengineeringeducatorsinthewesternworldwoulddisagreewiththe viewthattodaytheprimarypurposeofengineeringistoimprovethelotofindividualsand thesocietyinwhichtheylive.Centraltotheachievementofthatgoalisengineeringdesign, whichasBucciarelli[55]shows,isasocialactivity.Itreconstructssociety,apparentlywith littleattentiontotheconsequences[56].Socialreconstructioneducatorstaketheview thatwhile“manisshapedbysocietyandmancanshapesociety[...]Individualsmustfirst reconstructthemselvesbeforetheycanreconstructsociety”[57].
Theimplicationsofthisideologyfortheengineeringcurriculumanditsteachingareprofound.Withoutareconstructionofteachingthiswouldnotbepossible.Sofarthathas provedimpossibletoachieve.Ifteachingisconsideredtobeaprofessionalactivity,whyis itthattheactivityofteachinginhighereducation,andallthatthatentails,isnotconsideredtobeaprofessionalactivity?Giventhatthemindisthemostdelicateandprecious instrumentthatwepossess,whyarethatmanyeducatorsallowedtochargeintotheeducationalprocesswithlittlemorethananimplicitviewoflearningandteaching?Couldit bethattheydomoreharmthangood?Coulditbethatapparentlygoodintentionslead tosuicide?
1.7DISCUSSION
Fourideologiesthatbroadlycategorizeteachersarethebeliefstheyhaveaboutthepurposesof education,thenatureofknowledge,howstudentslearn,andhowthecurriculumwasdescribed. Theyapplyequallytoengineeringeducators.Thesephilosophiesarethedriversoftheteaching andlearningstrategiesadopted.Theyaccountforsomeofthetensionsthatexistwithintheengineeringeducationcommunity,andwhendeeplyheldtheyarepowerfulresistorsofchange. Changeisonlypossiblewhena“deep”understandingofthesedifferentphilosophiesisheldby alltheparticipants.Inthatcircumstancearationaldebateispossible,andthemeritsorotherwiseofaproposedchangecanbeevaluated.Itisassertedherethatmanyofthedebatesabout engineeringeducationareconductedata“surface”levelwhichpreventsunderstandingofdifferentpointsofview,andcausesany“in-depth”discussionoftheaimsofengineeringeducation tobeneglected.Toenable“in-depth”discussiontotakeplaceitisessentialthattheeducator hasdefensibletheoriesoflearningandphilosophy.

Williams[59]whoseanalysisoftheshortcomingsofengineeringeducationwaslittle debatedarguedthatthefragmentationofengineeringintoanumberofspecializationshaddeprivedthecurriculumofanythingthatwasspecificallyengineering.Istheresomethingthatis specificallyanengineeringcurriculum?Questionsofthisnaturecannotbeansweredwithoutan understandingofthephilosophicalissuesinvolved[60].Akeyquestionishowisadiscipline formed.Iftheengineeringdisciplineissimplytheapplicationofsciencetopracticalproblems, shouldittakenoteofTrevelyan’sargumentthattheexerciseispointlessunlessthepracticeof engineersistakenintoaccount?Ifitis,thennoticehastobetakenoftheaffectivedomain,and thatisprohibitedbythescholaracademicideologyandignoredbythosewhofollowthesocial efficiencyideology,eventhoughtheauthorsofthecognitive Taxonomy alsowroteataxonomy fortheaffectivedomain[61].Moreover,thispositioncannotbesustainedforthereissubstantial evidenceoftheimportanceoftheaffectivedomainintheengineeringliterature[62, 63].Both thelearner-centredandsocialreconstructionideologiesembracetheaffectivedomainintheir attentiontothewholeperson.

Ifengineeringisaboutimprovingtheworldinwhichwelive,thenengineeringeducators canhardlyavoidthepremisesofthesocialreconstructionideology.Thereare,forexample,many illustrationsofcoursesthatinvolvestudentsinsolvingengineeringproblemsfordevelopingnations(e.g.,[67]).Itmayalsobearguedthatengineeringdesignersarenecessarymembersofthis category,butsotheyareareofothercategories.Itisdifficulttosustaintheviewthataprofessionalengineeringeducatorcanbeamemberofonecategoryalone.JerryGravanderresponding tothispointwrote(personalcommunication):“everyactualprogramofengineeringeducation hascontent,intendedoutcomesbeyondtheclassroom,apedagogyandaconceivedsocialpurpose.Consequently,debatesaboutthecomparativeadvantagesanddisadvantageamongvarious programsofengineeringeducationareessentiallydebatesabouttheproperbalanceamongthese fourideologies.”
