Students in Open Distance Learning (ODL) face a myriad of challenges including a low proficiency in English. While research has identified vocabulary as important in improving language proficiency and the pertinent role of interaction in vocabulary development, there remains a dearth of research on how to enhance vocabulary in ODL, a context which is characterised by the distance between students and the institution. In searching for an intervention that would support vocabulary development, including interaction, while taking cognisance of the distance between students and lecturers, this study explored the use of mobile learning (mlearning). Because mlearning technologies offer ubiquitous flexibility and accessibility, they were deemed fit for purpose for ODL which is established on the principles of openness, flexibility and student‐centredness. Using the design‐based research (DBR) method within a pragmatic paradigm, this study designed, implemented and evaluated mobile‐based interventions for vocabulary development. The first phase of the study involved the analysis of the problem through a literature review. The literature and theoretical framework were used to ground the second phase of DBR, which included the development of the intervention prototype in the form of a mobile‐based vocabulary development app called VocUp. The intervention was implemented, tested and refined in three iteration stages, which formed the third phase of DBR. The iterations included a VocUp only stage, followed by a WhatsApp only stage, and ended with a VocUp plus WhatsApp stage. The last phase of DBR involved a reflection and a production of artefacts and guidelines for practice in ODL. Data were collected through interviews and WhatsApp chats from students registered for a first‐year English module. The results were 1) that vocabulary should be explicitly taught, allow for rehearsal opportunities and contain assessment while acknowledging the instrumental role of interaction; 2) mobile interventions should balance the pedagogic benefits with the technological qualities; and 3) the advantages and challenges of using WhatsApp and VocUp can be successfully combined into a hybrid model of both platforms. This study’s contribution to the body to knowledge includes the newly‐designed VocUp as an artefact; a revised model of the CoI theoretical framework called MODeL as well as principles guiding the application of the MODeL in authentic ODL contexts. / English Studies / D.

Abstracts in English, Zulu and Afrikaans / The worldwide growth of open distance and e-Learning cannot be denied, nor can it remain unnoticed. In the South African setting, which is the focus of this study, the increasingly high demand for higher education has also led to the development of distance education. However, the throughput rate for this mode of education has been consistently unimpressive for over a decade and this has led to high dropout rates. There is cause for concern regarding how best to assist students and improve throughput. Therefore, this research has focused on identifying strategies that can be incorporated to support sustained learning in South African ODeL. It considers issues such as the social inequalities, previous disadvantages, and ICT affordances that characterise South African ODeL students. This research took a qualitative research approach, using a case study that was conducted as a dissertation of limited scope. The aim was to unveil the best approaches that could be incorporated in South African ODeL in order to support sustained learning. The study attempted to understand such strategies, based on students' perceptions and reflections on their experiences while studying first-level modules in distance education. The case for this research study was the University of South Africa (UNISA), where eight student participants were interviewed, using semi-structured interviews to collect data. The findings of this study revealed that there are some readily available resources that the institution and instructors can use to promote sustained learning and improve student throughput. This research recommends frequent student surveys to discover student needs and the challenges that they experience. It also recommends improved communication with students, provision of financial aid, development of open educational resources (OERs), ensuring rapid delivery of study material, and the use of different methods of delivering learning content. It is important to note that the findings of this dissertation are of limited scope and cannot be generalised to the issues affecting the majority of South African ODeL students – this because the study was carried out at one institution and involved just one module and eight participants. However, these findings have the potential to enlighten ODeL stakeholders as to matters affecting some of their students. The findings could also provide valuable information for future large-scale research. / Ukudlondlobala kohlelo kohlelo lwemfundo evulekile nokufunda kude kanye nohlelo lwe-inthanethi akunakuphikiswa, futhi angeke kwathathwa sengathi akunakiwe. Ngokwesizinda seNingizimu Afrika, esiyindikimba yalolu cwaningo, izinga elikhulayo lokufuneka kwemfundo ephakeme nakho sekuholele ekukhuleni kwemfundo yokufunda ukude.Yize-kunjalo, izinga legalelo lalolu hlelo lwemfundo kudala lubonakala lungeluhle esikhathini esingaphezu kweminyaka eyishumi kanti lokhu sekuholele ekutheni kwehle izinga labafundi abayeka ukufunda. Kunomnako mayelana nendlela nokuthi abafundi bangancedwa kangcono kangakanani ukuze bathuthukise izinga labo lokusebenza. Ngakho-ke, lolu cwaningo selugxile ekutholeni amasu lawo angasetshenziswa ukuxhasa imfundo esimelele ohlelweni lwe-ODeL lwaseNingizimu Afrika. Lokhu kufaka izindaba ezinjengokungalingani komphakathi, ukuncishwa kwamathuba esikhathini esedlule, kanye nokwazi ukukhokhela uhlelo lwe-ICT okuwuhlelo oluyinsika kubafundi bohlelo lwe-ODeL eNingizimu Afrika. Lolu cwaningo lulandele indlela yocwaningo eyencike kwizinga lengxoxo (qualitative), ngokusebenzisa ucwaningo lotho olwenziwa njengedezetheshini enobukhulu obunqunyiwe. Inhloso kwaye kuwukuveza izindlela ezingcono ebezingafakwa kwi-ODeL yaseNingizimu Afrika, ukuxhasa imfundo imfundo esimelele. Ucwaningo beluzama ukuzwisisa amasu anjalo, asuselwa phezu kwemiqondo yabafundi kanye nokubheka ulwazi lwabo kube ngakolunye uhlangothi bafunda omojuli besigaba sokuqala sohlelo lwemfundo yokufunda kude. Ucwaningo lotho lwalesi sifundo lwenziwa eNyuvesi yaseNingizimu Afrika (UNISA), lapho abafundi abayisishiyagalombili befakwa imibuzo yenhlolovo, ngokusebenzisa inhlolovo yesakhiwo sikanxambili ngenhloso yokuqoqa idatha. Ulwazi olutholwe yilolu cwaningo luye lwaveza ukuthi kunemithombo elungisiwe esesimeni esifanele engasetshenziswa yiziko kanye nabayaleli ukuthuthukisa uhlelo lokufunda olusimelele kanye nokuthuthukisa umsebenzi wabafundi. Lolu cwaningo luncoma amasaveyi enziwa njalo abafundi ukubona izidingo zabafundi kanye nezinselelo abafundi abahlangabezana nazo. Ucwaningo luphinda futhi luncoma uhlelo oluhle lokuxhumana nabafundi, ukuhlinzekwa ngosizo lwezimali, ukuthuthukiswa kwemithombo yemfundo evulekile (OER), ukuqinisekisa kohlelo olusheshayo lokuhlinzekwa. ngomatheriyeli wokufunda, kanye nokusebenzisa izindlela ezahlukene zokwethula indikimba yokufundwayo. Kubalulekile ukukhumbula ukuthi ulwazi olufunyenwe lwedizetheshini wulwazi oluncane olubekelwe imingcele kanti lolu lwazi angeke lwafaniswa nodaba oluthinta iningi labafundi base-ODeL yaseNingizimu Afrika – lokhu kungenxa yokuthi ucwaningo lwenziwa kwiziko elilodwa futhi lwaxuba umojuli owodwa kanye nabadlalindima abayisishiyagalombili. Yize-kunjalo, lolu lwazi olutholakele lunethuba lokukhanyisela abasebenzisani njengezinto ezithinta abanye babafundi. Ulwazi olutholakele belunganikeza ulwazi olusemqoka mayelana nocwaningo olubanzi olungenziwa esikhathini esizayo. / Wêreldwyd het oopafstand- en e-leer groei ervaar wat nie ontken kan word of ongesiens kan bly nie. In die Suid-Afrikaanse konteks, wat die fokus van hierdie studie is, het die toenemende vraag na hoër onderwys ook tot die ontwikkeling van afstandsonderrig gelei. Die slaagsyfer vir hierdie vorm van onderrig is egter al vir langer as ʼn dekade deurlopend onindrukwekkend, en dit het tot hoë uitsaksyfers gelei. Daar is rede tot kommer rakende die beste maniere om studente by te staan en die slaagsyfer te verbeter. Die fokus van hierdie navorsing was daarom op die identifisering van strategieë wat geïnkorporeer kan word om volgehoue leer in Suid-Afrikaanse oopafstand- en e-leer te ondersteun. Die volgende kwessies is ondersoek: die sosiale ongelykhede, benadeling in die verlede, en IKT-status wat met Suid-Afrikaanse oopafstand- en e-leer-studente geassosieer word. ʼn Kwalitatiewe navorsingsbenadering is gevolg; ʼn gevallestudie wat uitgevoer is, is in die verhandeling van beperkte omvang gebruik. Die doel was om die beste benaderings te bepaal wat in Suid-Afrikaanse oopafstand- en e-leer geïnkorporeer kan word om volgehoue leer te ondersteun. Tydens die studie is daar gepoog om sodanige strategieë te verstaan op grond van studente se persepsies en hul refleksie op hul ervarings terwyl hulle eerstejaarmodules deur afstandonderrig studeer het. Die geval wat in hierdie navorsing bestudeer is, is dié van die Universiteit van Suid-Afrika (Unisa), waar daar semi-gestruktureerde onderhoude met agt studentedeelnemers gevoer is om data in te samel. Die bevindinge van hierdie studie het getoon dat daar geredelik beskikbare hulpbronne is wat deur die instelling en die onderriggewers ingespan kan word om volgehoue leer te bevorder en die studente se slaagsyfers te verbeter. Op grond van hierdie navorsing word aanbeveel dat opnames gereeld onder studente gemaak word om hulle behoeftes en uitdagings te bepaal. Verdere aanbevelings sluit in verbeterde kommunikasie met studente, voorsiening van finansiële steun, ontwikkeling van oop opvoedkundige hulpbronne, versekering van spoedige lewering van studiemateriaal, en die gebruik van verskillende metodes om leerinhoud te lewer. Dit is belangrik om te besef dat die bevindinge van hierdie verhandeling beperk in omvang is en nie veralgemeen kan word om die kwessies in te sluit wat die meerderheid van Suid-Afrikaanse oopafstand- en e-leer-studente raak nie – aangesien die studie by een instelling uitgevoer is en slegs een module en agt deelnemers behels het. Hierdie bevindinge het egter die potensiaal om vir oopafstand- en e-leer-belanghebbers lig te werp op kwessies wat sommige van hul studente raak. Die bevindinge kan ook waardevolle inligting vir toekomstige grootskaalse navorsing oplewer. / Educational Studies / M. Ed. (Open Distance Learning)
