EXECUTIVESUMMARY

This deliverable (D4.3) is in the format of a sequence of three demonstrations (corresponding toversions v1 - v3). This report is part of the first demonstration for v1/M9. The intention of thisdeliverablereportistoprovideaninsightintothefirstversionoftheeducationalextensionanditsintegrationwiththeunifieduserinterface(UUI).

This deliverable includes accompanying videos that demonstrate the integration of educationalextension with the UUI (D4.4). In this version, the focus of development has been on creation,programming and sharing tools as these are necessary tools for the first pilots. Based on thecollecteddatafromfirstpilots,furtherimprovementsandnewfunctionalitieswillbeaddedtolaterversions.

1 INTRODUCTIONFollowing the footsteps of deliverables D4.1 and D4.2, this is the starting point of design andimplementation of the pedagogical framework, including the 5 stage learning methodology (SeeD3.1,D4.1andD4.2)fromatechnicalperspective.Thus,inthisdocumentthefirstimplementationofeCraft2Learn’seducationalextension,whichwillactasagluetoconnectdifferent toolsused inthe 5 stages of eCraft2Learn’s learning methodology is implemented. In addition, thisimplementationwillalsoextendthefunctionalitiesofsomethesetoolstosupportthelearnerswithmore advanced features, such as artificial intelligence (AI) services and augmented realityvisualizations,intheirjourneytowardscreatingandlearning.

1.1. ECRAFT2LEARNLEARNINGMETHODOLOGY

eCraft2Learn is an ecosystem which is based on craft and project based teaching methods. Thismethodology includes 5 stages,which together guide the learner froman idea todeveloping andshowcasing,throughsharing,thefinalsolution(Figure1).

Figure1-eCraft2Learncraftandproject-basedmethodology(the5stages)

• Ideation:The learnersexplore theworld to findchallenges.Thisexplorationcanbe in thephysicalorvirtualworld(i.e.onlinecommunities).

• Planning: The learners collect information and material. They also start making projectplans.

• Creation: Through a co-design and co-creation process, the learners start creating theirsolutions.Thisstagemight involvemanydifferent technologiessuchasdo-it-yourself (DIY)electronics,visualization,simulationand3Dprinting.

• Programming: Learners add functionality to their crafted artefacts through high-levelprogramminglanguages.

• Sharing:Bysharingthesolutionsononlinecommunities,thelearnerscanlearnfromotherprojects,whilereceivingfeedbackfromdesigners,engineersandprogrammers.

Each of the aforementioned stages requires a different set of tools and materials. Developing acentral place (software) for managing these stages is the aim of the educational extension ineCraft2Learn.Suchasolutionwillmake iteasier tomanage the learners’ co-creationprojectworkandalsocanprovidethenadditionaltoolstoimprovetheirprojectsevenfurther.

InD3.1theideationstageisdescribedas(notethattheideationstageiscalledImagineintheUUIFig.2),sinceitwasassumedthatthelattertermwouldbeeasiertounderstandbythelearners):

“Ideationthroughworldexploration:Inordertoexplorethekindsofchallengesthatstudents or others face in their daily lives, a student could explore the worldphysically (e.g. taking pictures, exploring situations outside the classroom,newspapers, etc.) or virtually (e.g. through online support community discussion,online news, documents, local news/websites) and then decide what theirchallenge/problemwillbe.ThisprocessisalsoguidedbytheSTEAMcoach.”

4.4. PROGRAMMINGSTAGE

Deliverable D4.2 provides a set of recommended programming tools that cover a wide range ofpossibleapplications.Theseinclude:

• Snap! And Snap4Arduino: Snap! Is an open-source visual programming language. TheSnap4Arduinoflavourofithasbuilt insupportforcommunicatingwithArduinodevices(aspresented in the demo video), while original flavour of Snap! Can be used to programRaspberryPidevicesandGPIOpinswithease.

• ArduinoIDE:Whileoriginallyadesktopapplication,recentlyweb-basedversionofitisalsoavailable.TheprogramminglanguageisC-likeandtheSDKcanbeusedtogeneratecompiledcodetorunonArduinodevices.

• Scratch and Scratch4Arduino: Scratch can be seen as little brother of Snap!. It is a visualprogramming language and can be used to access the hardware (Arduino/Raspberry Pi).UnlikeSnap!,Scratchcannotbeeasilyextendedwithoutmodificationsinthesourcecode.

• Othertoolssuchas:ArduBlocks,AppInventor,PocketCode,NetsBlox.

InD4.3(v1)thefocushasbeenonintegratingprogrammingtoolswiththefollowingfeatures:

• Providevisualprogramming.• Can be easily extendedwith new components. This is especially useful when it comes to

addingnewfunctionalitiessuchasAICloudservices.• Provide open source solutions to allows the development team to make required

modificationsi.e.foraddingdataanalyticssupporttothesystem.• Caneasilyaccessthehardware(Arduino/RaspberryPi).

ThesepropertiesareallfoundinSnap!AndSnap4Arduinoprogrammingenvironments.Therefore,inD4.3 these toolsare integrated intoeCraft2Learneducationalextension.Thismeans thatAI cloudservices,dataanalyticsandfileservicesareincorporatedintoSnapandSnap4ArduinointhisversionoftheeducationalextensionandUUI.

4.4.1. AICLOUDSERVICESSeveralcompaniesofferAIbasedcloudservices,namely:Google’smachine learning, IBMWatson,MicrosoftcognitiveservicesandAmazonAIservices.Theseservicesvaryandnormallyinclude:textand speech analysis, image analysis, pattern recognition, etc. Although these are commercialservices,theyofferfreeservicesaswellforlimitednumberofqueriesperdaywhichisinmostcasessufficientforschoolprojectsassumedinthiscontext.

Theinterfacesfortheseservicesaredesignedforprofessionalprogrammers.Thus,inordertomakethese services available to learners simplified interfaces are required. Therefore, as part of theeducational extension a set of programming interfaces are developed that can easily access theservicesfromGoogle,IBMandMicrosoft.

The interfaces expand the Snap! programming language by adding new blocks that provide theprogrammerswithspeechsynthesis,speechrecognitionandimagerecognition.Theworkpresentedbelowcanbefoundinmoredetailhere(KahnandWinters2017).

4.4.1.2. SPEECHRECOGNITIONSince the recognition services present asynchronous behaviour, the Snap! blocks designed forspeech recognition rely on continuations. These blocks have a success and an error continuation.The error continuation is optional. As continuations might be a difficult topic to grasp for thelearners,aspecialoptionalblockisaddedthatsupportseventbroadcastingandaglobalvariable.Inthisway,theprogrammercanmakeacallto“listen”,receivebroadcastwhensomethingisreceivedand retrieve the utterance from the global variable.

The educational extension for Snap! creates snapshots of the Snap! and Snap4Arduino programswhile the learners are programmingwith these tools. The snapshot is then saved in the learners’GoogleDriveprojectfolder.

4.4.3. DATAANALYTICSANDDEBUGGINGTOOLSInordertoprovidethelearninganalyticsanddebuggingtoolswithuserdata,userinteractionwithUUI should be observed and reported back to learning analytics system. For version 1, theeducationalextensionrecordsuser interactionwithUUIwhen:1)theyopenatool,2)theycloseatool,and3)theyclickonhelpdialogsrelatedtoaspecifictool.Thisdataistimestampedandsentbackfordataanalysis.

4.5. SHARINGSTAGE

Sharingthelearners’resultswithothersand/orthecommunityisanimportantpartofeCraft2Learnlearningmethodology.Thiswillnotonlyallowthelearnerstosharetheirworkwithclassmatesandfriends,itwillalsoallowthemtoshowcasetheirwork(withmakercommunities),andhenceinteractwiththisthisonlinecommunitytoshareideasandsolutions.

Sharing also allows for opening up the design/program/etc. to other tools within or outside theeCraft2Learn environment. Some of the tools which are being integrated into eCraft2Learnenvironment,alreadyhave support for sharing functionality. In thisdemo,wepresent the sharingpossibilities between TinkerCad and Thingiverse and use this to provide the learners witheCraft2Learn Thingiverse App(s) that can be used to provide the learners with wide variety ofpossibilities.

In this deliverable and as part of the Educational Extension, we present an Augmented RealityVisualization tool for Thingiverse. This part is not directly integrated into UUI, but as seen in thedemovideoauser candesignanobject in TinkerCad, send it to Thingiverseand immediatelyusetheirmobilephonetovisualizetheobject inareal lifesettingthroughanaugmentedrealityview.This allows the learners to visualize the object in its final environment while tinkering with it inTinkerCad.

5 CONCLUSIONThis document and accompanying videos demonstrated the first version of educational extensionand its integrationwith the UUI. The online software includes tools that support the 5 stages ofeCraft2Learn methodology. It also extends some of these tools to provide the learners withfunctionalities such as using AI cloud services in Snap! Programs, augmented reality visualizationtools for 3D modelling and auto-save features for programming tools that saves program filesdirectly on the learners’ project space. This version also includes data gathering services for dataanalytics tools that laterwillbeusedtoprovidethe learnersandteacherswithuseful informationduringtheprojectworkanddebugging.

Thissetoffunctionalitiesforversion1areselectedtoprovidethebasicsforthefirstroundofpilottests. The results of the pilot studies will provide useful insight into the next versions in thedevelopmentofeducationalextensionandUUI.
