IntroductionThereareapproximately93millionchildrenworldwide(i.e.approximately1 in20ofthoseaged14oryounger) living with a moderate or severe disability of some kind [12]. This staggering statisticnecessitates the development of assistive tools that can help sustain a healthy life for these childrenirrespective of their disabilities. In recent years technological advancements have spearheaded thedevelopmentof innovativesolutionstomeettheneedsandaspirationsofdisabledchildren.However,accordingtotheWorldHealthOrganization, inmanylow-incomecountriesonly5-15%ofthepeoplewhoneedassistivetechnologyareabletoobtainit[12].Thisisprimarilyduetothehighcostinvolvedindeveloping, procuring and maintaining such technologies in these regions of the world. AssistivetechnologyisdefinedbytheTechnology-RelatedAssistanceAct(TechAct)of1988(P.L.100–407),andtheIndividualswithDisabilitiesAct(IDEA)of1990(P.L.101–476),as“anyitem,pieceofequipment,orproductsystem,whetheracquiredcommerciallyoff-the-shelf,modified,orcustomized,that isusedtoincrease,maintain or improve the functional capabilities of individualswith disabilities.”[5] There aretwo purposes of assistive technology. First, technology can augment an individual’s strengths bycounterbalancing the effects of a disability; and second, it can provide alternative methods forperformingatasksothatdisabilitiescanbecompensatedfororbypassedentirely[5].Severalassistivetechnologieshavebeen introducedtoaid inday-to-daytasks (e.g.powerchairs, screenreaders,etc.),but therehasalsobeena recent increase inemergingassistiveeducational technology,whichcanbeused to support andenhance the learningenvironment for childrenwithdisabilities. To this end, theTechBridgeWorld (TBW) research group at CarnegieMellonUniversity (CMU) has partneredwith theMathru Educational Trust for the Blind (Mathru Trust) in Bangalore, India to develop economicallyfeasibleassistivetechnologicalsolutionstoeducatestudentsatTheMathruCenterforDifferently-Abled(Mathru Center). This centerwas newly developed byMathru Trust to address the growing need foreducationalresourcesforchildrenwithmultipledisabilitiesorchallengesotherthanblindness.

Background

TechBridgeWorldTBW is a research group that builds partnerships withunderserved communities internationally to create culturallyappropriate technology that adheres to each community’svision of progress (Figure 1). Founded in 2004, TBW leadsinnovation and implementation of technology solutions tohelp address challenges in technologically underservedcommunities across the world. They invent new tools,customize existing technology, and inspire and train futureresearchers and technologists. Based at CMU,TechBridgeWorldemploys theknowledgeand imaginationoffaculty,staffandstudentsinallofourprojects.

iSTEPTBWlaunchedtheiSTEPprograminthesummerof2009toprovideCMU students a real-world, real-work experience in applying theirknowledge and skills for creative problem solving in unfamiliarsettings (Figure 2). iSTEP is a 10-week unique summer researchinternship that provides students with the opportunity to conducttechnologyresearchprojectsinunderservedcommunitiesacrosstheworld. Both undergraduate and graduate students from CMU’sPittsburgh and Doha campuses are eligible to apply. TogetherwithTBW, the iSTEP team collaborates with local partners to betterunderstand the needs of the community and research technologysolutions that could help address some of those challenges.

TheMathruCenterforDifferently-AbledIn2001,Ms.GubbiR.MukthafoundedtheMathruEducationalTrustfortheBlind (Mathru Trust), which is an entity funded by private donors whosupport the education and development of blind children in India. ThatsameyeartheMathruTrustwentontoestablishtheMathruSchoolfortheBlind (Mathru School) in Bangalore, the largest city in the Indian state ofKarnataka. TheMathru School is dedicated to the growth, education andcare of visually impaired and blind children. After almost a decade ofsuccess with this school, the Mathru Trust sought to expand its reachthrough the development of a center to support students with multipledisabilities. The work described in this report was conducted at the newcenterforstudentswithhearingimpairmentsandmulti-sensorydisabilities.

Intheyear2010,theMathruTrustinitiated“ProjectNandini”undertheguidanceofSenseInternationalIndia (SSI). Themotivationbehind thisnewundertakingwas the compelling storyof a young, visuallyimpairedstudentnamedNandini(Figure3).In2006,NandinienrolledattheMathruSchool.Shespentfouryearsatthisschoollearningbrailleanddevelopinglifeskillsalongwithherpeers.Inthesummerof2010, she contractedchickenpox.Her family lived ina rural and impoverishedareaof IndiaandwasunabletoobtainnecessarymedicalprovisionstotreatNandini.Asaresult,shelostherhearingability,and is now both visually and hearing impaired. Project Nandini was established to cater to theeducationalneedsofstudentslikeNandini,whohavemultipledisabilities.

Under this project, in 2012 the Mathru Trustinstituteda free, residential schoolentitled the“Mathru Center for Differently-Abled” (MathruCenter) to support the education anddevelopment of hearing impaired and multi-sensory disabled children. This new center islocated in the Srinivasapura region, which isabout six kilometers away from the MathruSchool in Yelahanka (Figure 4). In addition todrawing inspiration from Nandini’s story, thecenterwasalsosetupprimarilyduetothefactthat many of the visually-impaired students at

theMathruSchoolalsohadotherformsofdisabilitiessuchashearingimpairment,deafness,muteness,cognitive challenges, cerebral palsy and speech impediments. The focus of the Mathru Center is toprovide studentswith an all-round education by supporting their social and emotional development,improving their communication, cognition and mobility skills, and enabling them to independentlymanage their day-to-day activities. In addition to its emphasis on education, theMathru Center alsohosts a range of different services for the community, including computer training and vocationalsupportforruralwomen.Thecenter’svariousactivitiesaredescribedbelow.

NeedsAssessmentThefocusofthisresearchstudywastoconductathoroughneedsassessmentwithstaff,teachersandstudentsattheMathruCenter.TounderstandtheneedsoftheMathruCenter,researchersfollowedtheprescribed CMU Institutional Review Board (IRB) guidelines to interview teachers and staff, conductobservations of critical activities at the center both inside and outside classroom, elicit opinions of alocal special education expert, and administer participatory design experiments with teachers andaffinitymatchingwithstudents.

ObjectivesTheobjectiveofthisresearchinitiativewastounderstandwhetherandhowassistivetechnologycanbeutilized to enhance the learning and teaching experiences of students and teachers at the MathruCenter. In particular, researchers observed and assessed ways in which students with hearingimpairments and multi-sensory disabilities could be assisted in education through technology. Thisprovided a better understanding of the current educational state of students at the Mathru Centerincluding the needs of both teachers and students, and ways in which technology could be used toenhance the learning environment andoutcomes for students. Basedon data collected in this study,follow-upresearchcanbepursuedtodeveloptoolstobenefittheMathruCenter.

According to Mukuria and Eleweke, a major argument for the activeinvolvementofparentsintheeducationoftheirchildrenwithhearinglossisthat“95%ofthesechildrenare born to hearing parentswho have no previous experience and knowledge of raising a childwith

hearingloss.”[3]Theactiveinvolvementofparentsleadstobetterlearningoutcomesforthestudent.Mukuria andEleweke state that the goal of early intervention fromparents in the educationof theirchild is to foster effective parent–child communication and to provide an opportunity to acquirelanguage intheappropriatemodality(signorspoken).Thefactthathearing impairedchildrenarenotable to listen to their own voice poses an additional challenge to the learning and acquisition of alanguageduring theearly stagesof theirdevelopment.Thereare threemainavenues for thehearingimpairedtoaccess language:speechreading,hearing (formildormoderatehearing impairment),andsignlanguage[6].Somemayalsoemployacombinationofthesethreemethods,ortechniquesincludingvisual cues and face-reading to communicate with others [6, 10]. There are some disadvantagesassociated with each technique. Most notably, only about 50% of English speech reading can beobserved through lipswhile theother50% is spokenbehind closed lips,whichdoesnot facilitate theprocessofreadinglipstounderstandwhatthespeakeristryingtoconvey[6].

Inspecialeducational institutionsthatcatertotheneedsofstudentswithdisabilities,educatorsoftenutilize visual aids to teachhearing impaired students. This sameeducational techniquehas alsobeenobservedattheMathruCenter.Throughtheuseofimages,hearingimpairedstudentsarebetterabletograspconceptssuchasthenamesoftheanimals,differentmodesoftransport,humanbodyparts,etc.A number of studies pertaining to hearing impaired education consider visual aids to be a valuableeducational tool. Because sign language is relied heavily upon to communicate, deaf students arefrequentlydescribedasvisual learnersbytheirteachers,deaf individuals,andothers[1].Likereading,learning sign language is a verbal skill, even if it depends on vision rather than voice. Hence, apreferenceforsignoverspeechasthelanguageofinstructionisnotsufficienttoclassifysomeoneasavisuallearner[1].Therefore,itisimportanttoassesshearingimpairedstudents’visual-spatialabilities,in addition to their cognitive skills, prior to developing any kind of intervention to enhance theireducational experience. Having a good understanding of spatial relations is particularly important formastering mathematical concepts. For deaf students who have greater spatial relation skills, havingaccess to diagrams representing conceptual and relational information within a math problem canfacilitatetheirarrivingatasolution[1].

Special educators for primary classes often first teach students key concepts through reading andwritingactivities.Signlanguageisalsousedtoexplainthosesameconcepts.AccordingtoMukuriaandEleweke,“studentsusetheirknowledgeandskillsintheirfirstlanguage(signs)tolearnliteracyskillsintheir second language (English).” [3]Additionally, research related to thecognitiveandmetacognitiveabilitiesofdeaf learners, showed thatdeaf students tend tobe less likely than theirhearingpeers toautomaticallyutilize cognitiveabilities andknowledge that theyareknown tohave [1]. This indicatesthatlessonsneedtobeplannedinamannersuchthatthedifferentlearningneedsofhearingimpairedstudentsaresufficientlymet.AccordingtoMukuriaandEleweke,planningmusttake intoaccountthefollowingrequirements:“realisticdiagnosticassessmentofeducationalneeds, instructionthat focusesonspecificneeds,assessmentofgrowth,andevaluationofinstruction.”[3]

The educational approach for a hearing impaired student is radically different from that applied tostudentswhoaredeafblind,whichisaconditionindicatingthepresenceofadualsensoryimpairment,which involves the auditory and visual senses [2]. However, not every deafblind individual is either

completely deaf or completely blind [11]. Still, the impairment of both senses either partially orcompletelyposesuniquechallengesintheeducationandlanguagedevelopmentofdeafblindstudents.Each individual has fiveprimary senses to express and receive stimuli from the environment. Out ofthesefive,twoofthemarechieflyused:thevisualandauditorysenses.Inthecaseofdeafblindpeople,these senses are impaired and they have to therefore primarily depend on their sense of touch tointeractwiththeirenvironment.Touchandtasteareclosesenses,givinginformationonlyaboutwhatishappeningnow,withinarm’sreach[2,11].Themostwidelyusedtechniquetodirectlyteachdistancetoa deafblind student is the hand-under-hand approach that takes into account exploration withenvironmental objects [11]. Furthermore, the earliest technique ever used to teach language to adeafblindstudentinvolvedfingerspellingoftheAmericanSignLanguage(ASL)alphabetinthepalmofthe student’s hand.Using this hand alphabet technique, the studentwas taughtwords and conceptsabout her environment and the world [2]. Since most deafblind people have residual vision and/orhearing capabilities, appropriate educational techniques are used to alignwith and capitalize on thatdeafblind student’s most optimal sense(s), including partial hearing and/or sight. These techniquesinclude a combination of one or more of: (1) sign and body language, (2) hand gestures and (3)movements.Inaddition,“tactilesensesareoftenusedtoexploreenvironmentsandcommunicate”[2][11].Forexample,deafblindstudentswhohavelessvisualefficiencymayprimarilyusethehand-over-handapproachortactilemodeofsignlanguage.It isalsoimportantthattheeducationalenvironmentfordeafblindstudentsconsistofaclassorderoraconsistentclassactivity[2].Thisentailsestablishingaspecificorderofclassactivitiesthatenhancestheirlearning.Forinstance,asthestudententershis/herclassroom, the student approaches a specific shelf that contains objects that represent activities thathe/she will do during the day [2]. Other devices and techniques used in the education of deafblindstudents for communication purposes are: hearing aids, tactile signing, interpreting services,communicationdevicessuchasTellatouch(amanualbraillewriter),braillereading,large-printreading,tactilecommunicationcards,braillecardsandcardswithraisedlinesorimages[2].

TheMathruCenterenrollsstudentswhodemonstratetypicalcharacteristicsofindividualswithcognitivedisabilities. According to Bakken, these include: “short attention spans, problems with short-termmemory, speech and language difficulties, deficiencies in generalizing information to new situations,challengeswithmotorskills,andlowfrustrationtolerance,especiallywithregardtoacademiclearningandabstract instructional activities.” [5] To cater to theeducational needsof studentswith cognitivedisabilities,itisvitalthatthelearningmaterialpresentedtothestudentisinagrouporaclusterform,ratherthan inarandomorder[5].Educationaltechniquesshouldalso includepracticewithflashcardsandpicturesinadditiontoarepetitionoftheeducationalcontent[5].Othermethodologiesthatplayasignificantrole intheeducationofstudentswithcognitivedisabilities includemodeling, imitation,andlearningthroughobservation[5].

AssistiveTechnologyforDifferently-AbledStudentsSeveral computer-based applications exist for hearing impaired students. A research team based inIndonesia developed an Indonesian Sign Language Computer Application that is designed to assistpeople, especially childrenwith hearing impairments to learn the Indonesian Language called Bahasa[6].Thisapplicationcomeswithsixmodules:(1)the“DictionaryModule”showsasignlanguagevideoorspeech reading video of theword entered, (2) the “Picture SelectionModule” allows users to createsentences in the Subject-Predicate-Object-Adverb (S-P-O-K) pattern using available pictures, (3) theWriting Sentence Module allows users to create sentences by typing words, (4) the “Free SentenceModule”allowsteachers (andparentsofchildren)toarrangesentencesthatarenotaffirmatives (e.g.questions,negativesentences, imperatives), (5)the“FingerSpellingModule”allowsusersto learnthefingerspellingforaperson’snameorforwordsthatdonothaveasignlanguage,and(6)the“NumeralSignMode” allows users to learn the numeral sign for numbers. This application can also serve as adigitaldictionaryforBahasaIndonesianSignLanguageforthosethatsupportsignlanguageteaching[6].

Anotherinternet-basedapplicationisthe“SignOnOne,”whichteachesbeginner-levelEnglishusingsignlanguage as the language of instruction [7]. This online course is comprised of 10 lessons on topicsrelevant to the Internet and thedeaf. “SignOnOne”operatesunder thepremise that English learningshould beginwith thewritten language taught using sign language.

ResearchMethodsA variety of methods were employed to gain insight into the needs and challenges of teachers andstudents at theMathru Center. These included observations, shadowing teachers, teacher interviewsand participatory design methods including card sorting and an affinity matching exercise. Thesetechniquesaredescribedbelow.

ObservationsResearchers documented their observations across all classrooms at theMathru Center. In addition,observationswereconductedduringspecialeventsandrecreationalactivitiesatthecenter,inordertogaininsightintostudents’socialinteractionsandinterestsoutsidetheclassroom.

ShadowingThis is a contextual inquiry research method used to observe participants in their day-to-dayenvironment.ResearchersshadowedfourteachersattheMathruCenterduringthecourseoftheirworkday to understand the students’ and the teachers’ daily schedule. This was done regularly over thecourseof thenineweeks.Shadowingenabled researchers to immerse themselves into theenduser’senvironment,whichallowedforindepthobservationofclassesandthetypicalbehaviorofstudentsandteachers.

InterviewsFour teachers at the Mathru Center were interviewed.This included a new teacher who had extensive fieldexperience working with hearing impaired students inrural India. Another one of the teachers had priorexperienceworkingspecificallywithstudentswithmulti-sensory disabilities. Teachers were interviewedindividually and in-person in order to obtain detailedinformationoneach teacher’suniqueexperiencesat theMathruCenteraswellasatpriorteachingappointments(Figure9).

For one activity, students and teacherswere separately asked to sort a series of previously designedcards based on the difficulty level of the prompt. After the activity, answers and the difficulty ratingprovidedby the teacherswerenotedand similarities across teacherswerenoted.Cards thathad themaximumratingswereanalyzed.Asimilarexercisewasdonewiththestudentsinthe2ndstandardbutthepromptsprovidedtostudentstoorganizewererelevanttotheirexperience.Thishelpedresearchersunderstandwhich aspects of their teaching and learning experience are challenging for teachers andstudents,andalsohighlightedareastofocusonwhendevelopingassistivetechnologiesforcenter.

In the second affinity matching activity for students, researchers provided participants with a set ofpictures and asked them to indicate their affinity for the topic or subject by affixing a correspondingemoticon(expressingthreedifferentemotions:happy,sadorneutral)nexttothatimage.Studentswerethen asked to discuss with the researcher why they felt a certain way about specific subjects. Thistechniquehelped inspire students to consider subjects and topics that theywould like to learnmoreabout. This exercise was analyzed by providing numerical values to each of the “affinity” levels. Forexample,asmileyfacewasgivena“+1”whileaneutralfacewasgivena“0”andafrowningfacewasgivena“-1”.Informationcollectedthroughthisactivityhelpedresearchersmakerecommendationsforpossible technology interventions that would appeal to the teacher and student population at theMathruCenter.

ParticipantsParticipants in the research study includedboth teachers and students.A totalof four teacherswereinvolved in the research study. Three of the four teachersworked exclusivelywith the studentswithhearing impairments. One of the three teachers had prior experience in the field andwas trained inIndian Sign Language, while the other two teachers were trained after their appointment. A specialeducator with extensive experience with students with multiple disabilities was also included in theresearch. All 33 of the students enrolled at theMathru Center were included in the research study.Therearecurrentlyfourtypesofclassesofferedatthecenter:

(1) Multi-sensoryclass(MSI),whichincludeseightstudentswithmulti-sensorydisabilities;(2) 1ststandard,whichincludesfivestudentswithhearingimpairments;(3) 2ndstandard,whichincludesfourstudentswithhearingimpairmentsand(4) NurseryandPre-Nursery,whichincludes16studentswitharangeofdisabilities:

• Eighthearingimpairedstudents;• Twostudentswithbothcerebralpalsyandspeechimpediments;• Twostudentswithbothhearingimpairmentsandlearningdisabilities;• Threestudentswithcognitivechallenges;and• Onestudentwithbothavisualimpairmentandcognitivechallenges.

FindingsIn depth contextual inquiry at the Mathru Center through observations and shadowing teachersrevealed the distinct needs of teachers who work with hearing impaired students versus those whoworkwithstudentsintheMSIclass.

SurveyofTeachingToolsAt theMathru Center, teachers predominantly use flash cards as teaching aids. Some of these flashcards are embossed so that the students with visionimpairments can interpret them through touch (Figure10).Flashcardsarealsousetodescribepartsofhumanbody, animals, trees and various objects such as a ball,table,etc(Figure11).Inadditiontoflashcards,teachersalsousefigurinesofanimalstodescribethemtohearingimpaired students (Figure 12).

TimeManagementThis was identified as most difficult across allclassrooms with three out of four teachers rating“time management” as one of the top threechallenges during the card sorting exercise.Teachers mentioned that although they chart outwhattheyhavetocoverduringeachclass,theyarerarely able to complete lessons as planned sincethey need to cater to the varying capabilities andneeds of their students.

GettingAppropriateTeacherTrainingTeachers who came to the institution with notraining believed that this was the most difficultaspect of their experience, but at the same timerated “learning sign language” as easy. Masteringsignlanguagealonewasinsufficienttohelpmanagetheirvariousworkresponsibilities,particularlygiventhat these teachershadnoprior formal training towork with students with hearing impairments.

AffinityMatchingThis activity was conceptualized to reduce theoverheadoftranslatingtexttothestudentsandtoencourage them to interpret the activity anywaythey want to (Figure 16). Students unanimouslyrated geography, learning about animals and thesolar system as the highest out of nine picturesrepresenting different objects, professions andfieldsofstudy.Onlyonestudentwasinterestedinthe human body, but three out of four studentswere interested in doctors/medicine.

Thereare,however, somechallenges toconsiderwhendevelopingsuch technology for teachers.Oneissue is that each teacher’s base level experience and skills can vary significantly, so it could bechallenging toestablish tools that can cater to the various trainingneedsof teachers.With regard tocreatinganysignlanguagetechnology,theprimaryconcernisthatthesignlanguageusedattheMathruCenterisalocalvariationofIndianSignLanguageandhasnoofficialdictionarytoreference.

Therefore,developinga tool to teach this sign languagecouldprove tobedifficult.However, there isdocumentation thatoutlines thecurrentprocessorgeneral steps that thecenter takes toorientnewteacherstothisspecificversionofsignlanguage.Thisinformationcouldfacilitatethetechnologydesign,butperiodic checkswould still benecessary toensure the technology content isup-to-datebasedonanychangesthecentermayhavemadetotheirprocessfortrainingteachers.

PotentialChallengestoDataCollectionPotentialchallengestodatacollectioninclude:

1. Communicatingwithstudentstoobtaineitherqualitativeorquantitativedatacanbedifficult.2. Access to a qualified and reliable person to help translate informationmight be necessary if

researchersandparticipantsdonot speakacommon language. Locating suchan individual toassistwithtranslationmightbechallenging,especiallyinthecaseofsignlanguagetranslations.

3. Given thatall studentsat thecenterareminors, it isnecessary tohavea teacherorguardianpresent to help supervise and guide any testingwith students. This too can pose difficulties,particularlyintermsofschedulingtestingsessions.

PossibleConfoundingFactorsUsing a teacher to translate for the researcher can have both positive and negative consequences.Studentsaremorecomfortableandfamiliarwiththeirteacher,whichcanbehelpfulinextractingmoreaccurate information. At the same time, however, it is also possible that the teacher’s presencewillinfluence the student behavior and responses. Additionally, teachers may inadvertently bias theirtranslations of student responses. Such biases and confounding factors will need to be taken intoaccountwhenanalyzingdata.
