Text in English / In a quest to identify best practices in teaching courses in English for Specific Purposes (ESP), this study investigated effective teaching of an online English module in an Open Distance Learning (ODL) environment. Although ODL is attractive to both students and lecturers, there are significant problems regarding how learning, teaching, interaction and assessment should be conducted in this context. The problems are exacerbated by the limited knowledge of using the online systems and constraints linked to time spent on tasks. The study adopted the qualitative research approach, using a case study design and data collected from three research instruments, namely online questionnaires, an online observation schedule and a content analysis schedule. The research population in the current study comprised students, lecturers, and e-tutors based at one ODL university. In order to engender best practices of effective teaching in an ODL environment, the Community of Inquiry (Col) framework and Zone of Proximal Development (ZPD) theory were applied to the research findings of the current study. The findings indicate that effective teaching of an online English module in an ODL context could take place when content is effectively structured; assessment reflects course content; there is teamwork and collaboration amongst lecturers; students effectively interact with the material, lecturers/e-tutors, and with each other. The findings of this study add to the volume of research on best practices for effective online ESP teaching in ODL higher learning institutions. / English Studies / D. Litt. et Phil. (English)

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.
