Despite widespread use of web-based e-learning applications, insufficient attention is paid to their usability. There is a need to conduct evaluation using one or more of the various usability evaluation methods. Given that heuristic evaluation is known to be easy to use and cost effective, this study investigates the extent to which it can identify usability problems in a web-based e-learning application at a tertiary institution. In a comparative case study, heuristic evaluation by experts and survey evaluation among end users (learners) are conducted and the results of the two compared. Following literature studies in e-learning - particularly web-based learning - and usability, the researcher generates an extensive set of criteria/heuristics and uses it in the two evaluations. The object of evaluation is a website for a 3rd year Information Systems course. The findings indicate a high correspondence between the results of the two evaluations, demonstrating that heuristic evaluation is an appropriate, effective and sufficient usability evaluation method, as well as relatively easy to conduct. It identified a high percentage of usability problems. / Computing / M.Sc. (Information Systems)

In the world in which we live today, information and communication technology (ICT) has proliferated in all spheres of society, including in the corporate, social and academic arenas. Within these arenas ICT has made noteworthy contributions. In the academic space, which is the focus of this study, ICT has made a significant contribution to the communication and consultation between students and higher education institution staff. One such example has been the emergence of learning management systems (LMSs) in higher education institutions, both locally and globally, with LMSs providing higher education institutions with several possibilities as regards facilitating the online teaching and learning process. Nevertheless, research has shown that there is underutilisation of LMSs throughout the world. The purpose of this study, therefore, was to investigate the utilisation of LMSs in an open and distance learning (ODL) institution in South Africa to ascertain whether they are being used to their full potential. / Educational Studies / M.

Technological advancement has changed the way things are done in this era. Instructing and erudition process in conventional and Open Distanced and e-Learning (ODeL) is no exception, thus, creating a stint in the manner in which educators educate and the manner wherein students learn. This dissertation focusses on the role of ICT in ODeL environment. Guided by the transactional distance theory and the rhizomatic learning, this study tried to investigate the role of ICT in ODeL environment. The design was to investigate: (a) The effectiveness of ICT tools for instructing and learning; (b) whether ICT boost learning interaction; (c) foster flexibility; (d) supports the students to make decisions; and (e) allows students to connect learning in ODeL. The study utilized a blended techniques approach, and data was congregated through a questionnaire and interviews. A sample of 52 registered postgraduate students in the master of education (M.Ed programme) and seven lecturers within the College of Education were purposively and conveniently selected in the study. The survey questionnaire comprised of 53 question items for students, and 48 question items questions for lecturers. The questionnaire for both students and lecturers also had open-ended questions. Considering distance learning, it was difficult for the researcher to administer a questionnaire using any other method except the online tools. The congregated data was analysed utilizing descriptive and inferential statistics. The outcomes revealed that the integration of ICT in ODeL environment was effective and enhanced the educational process, promote interaction, foster the flexibility of the education programmes, support student autonomy and allow students to connect with different learning nodes. It was established in the study that ICT in ODeL has helped in transforming the education process. The study recommends that the institution should avail ICT facilities and provide users with high speed Internet. The institution should also make provision for technical support to users. Furthermore, both students and lectures should be armed with relevant technological know-how and dexterities. / Science and Technology Education / M. Ed. (Technology Education)

There is a paramount need for online university education to effectively contribute in the development of students' ability to construct and create new knowledge. Online learning should thus go beyond the production of knowledge for knowledge's sake, but should result in relevant and meaningful learning on the part of the online learner. In addition, online learning ought to result in the application of knowledge to practice. While gains made by constructivism and observational learning are well documented, research addressing online media blends that best encourage constructivist and observational learning in open and distance and e-learning (ODeL) contexts is limited. In addition, guidelines that can be used by online learning facilitators and policy makers regarding media for constructivist and observational learning were lacking when this research was conducted. The research was deemed significant in contributing to the development of an online learning framework that could be used to guide policy formulation and practice in the area of online course implementation in ODeL institutions. Using an explorative qualitative approach, this study explored online media blends for constructivist and observational learning. The study comprised three phases. The first phase was a meta-ethnography study whose objective was to synthesise previous research theses in order to gain an understanding of lecturers' and students' experiences of online media, constructivism and observational learning. The second phase consisted of a phenomenological study conducted at the University of South Africa, to explore lecturers' experiences of online media in the facilitation of constructivism and observational learning. The final phase of the research was the development of a framework based on constructivism and observational learning to guide online teaching and learning. The findings of this research study revealed that lecturers did not use media blends to a large extent in their interaction with students. The study indicated that some cognitive processes need to be exercised on the part of the facilitators when online learning is offered. It is concluded that during the curriculum planning phase, lecturers should decide on methods and media to arouse the students' attention during online courses. This also implies a more reasonable lecturer­ student ratio because large numbers of students per lecturer is not feasible in online learning. / Curriculum and Instructional Studies / D. Ed.

In higher education institutions, virtual learning systems (VLSs) have been adopted, and are becoming increasingly popular among educators. However, despite this ubiquity of VLS use, there has not been widespread change in pedagogic practice to take advantage of the functionality afforded by VLSs. Knowledge of the actual usage of e-learning systems is limited in terms of what specific feature sets are deemed useful, and how this influences system usage. VLSs have a suite of tools with associated functions/features and properties, as well as non-functional system characteristics. In addition, these systems incorporate pedagogic features to cater for online teaching. Educators in higher education, who are the chief agents of e-learning, are confounded by system-related, pedagogic, organisational, user difference and demographic factors that influence VLS usage. Virtual learning system usage involves system feature usage extent and frequency, total system usage and usage clusters. The aim of this study is to develop a model representing the factors that influence usage of VLSs in higher education. The links between system usage and system-related factors, pedagogic factors, organisational factors, user-difference and demographic factors is researched. This research incorporated a literature study, a pilot study, interviews and surveys. A case study research strategy was combined with a mixed methods research design. The results of the qualitative analysis was triangulated with the findings of the quantitative analysis and compared to the findings of the literature study. The study was conducted at two residential higher education institutions (HEI), namely, University of KwaZulu-Natal and Durban University of Technology. The main contribution of this study is the Virtual Learning System Usage Model (VLSUM) representing the factors that influence VLS usage in residential higher education institutions. The proposed VLSUM is based on the empirical results of this study. VLSUM can be used by managers of educational technology departments and instructional designers to implement interventions to optimize usage. The constructs of VLSUM confirmed existing theories, replicated and synthesised theories from different fields, and extended existing models to produce a new model for understanding the factors that influence VLS usage in higher education. / Computing / D.

The teaching model in Open Distance Learning is moving towards fully integrated information and communication technology applications, therefore, academic lecturers need to have a strong comfort level with the use of technology tools. The academic lecturers are qualified and experienced subject matter experts but this does not translate to having the necessary technical competencies to do online teaching. They consequently could experience feelings of incompetency to facilitate courseware on a technology platform. The study identified the factors that influence the user experience when using a Learning Management System (LMS) in an academic institution. The research design comprises a convergent, parallel design mixed-method case study. A literature review was conducted to abstract the factors that influence the user experience into a conceptual framework. An expert review was conducted to validate the conceptual framework and then a questionnaire-driven survey was performed. The quantitative analysis of the survey results revealed that eight of the nine factors proposed in the conceptual framework do have an influence on the perceived user experience of the academic when using the LMS. The qualitative analysis revealed that all nine of the identified factors do have an influence on the perceived user experience of the academic when using the LMS. The contribution of this study is to present a conceptual framework of the factors that influence the user experience of the academic when using an LMS to improve our understanding of the experience of the academic and the practical challenges involved for academics that have to facilitate learning in an online environment The findings should be of interest to developers of LMSs and to institutions in support and training of academics that have to use the LMS. / School of Computing / M.

This research examined lecturers’ perspectives on the academic use of Facebook, specifically for teaching, in a higher education institution in Gauteng, South Africa. A survey research design was followed, and semi-structured interviews were conducted. The study sought to fill the gap in the Social Networking Sites literature by focusing on lecturers’ perspectives, ascertaining how lecturers use Facebook as an academic teaching tool and determining the advantages and disadvantages thereof, and attempting to add to the debate on whether or not higher education settings could add the use of Facebook to their range of practices that may enhance teaching. The sample comprised fourteen respondents. It has emerged that lecturers are not, for the most part, utilising Facebook as an academic teaching tool. Based on the findings, a framework on how lecturers could integrate Facebook into academia is proposed. / Computing / M. Sc. (Computing)

Mobile learning has developed into an essential component within the education landscape and, with two billion users worldwide, the social media platform WhatsApp has become a prominent feature in this domain. Nevertheless, with ambiguity in the literature about the effects of WhatsApp on teaching and learning and especially a paucity of research measuring collaboration on WhatsApp in relation to students’ academic achievement. The purpose of the study was to explain and predict WhatsApp’s effect on academic achievement using a quantitative questionnaire. The results suggest that increased collaboration on WhatsApp may improve academic achievement. Additionally, improving other aspects, such as active learning, trust, support, formality, interaction and interdependence, may enhance collaboration and, in turn, improve academic achievement. The study has value by providing measurable scientific evidence about the effects of WhatsApp on learning that can be incorporated into the design of teaching and learning activities with WhatsApp to improve academic achievement. / Uhlelo lokufunda uhamba (Mobile learning) selikhule ladlondlobala laba yisigaba esibalulekile ngaphansi komkhakha wemfundo kanti, lolu hlelo selunabasebenzisi abangamabhiliyoni amabili emhlabeni wonke jikelele, uhlelo lwenkundla yezokuxhumana komphakathi lwe-WhatsApp seluyinkanyezi egqamile kulesi sizinda.

Abstract in English, Sesotho and Zulu / The occurrence of Open Distance and e-Learning revolutionized Higher Education Institutions for students to access instruction at anytime and anywhere. Students benefitted instruction of anytime and anywhere in one of the Technology Education courses in ODeL from the e-tutors. As a result of the support from the e-tutors, the curriculum was designed to place a strong emphasis on the design process as the core around which the teaching of the curriculum should revolve. However, it is still not clear how effective is the content knowledge which relates to the design process from the e-tutors. In acknowledgment from such a gap, this study aimed to determine the relationship between the e-tutors’ technological, pedagogical, content knowledge of teaching design process within Technology Education specialization. In order to achieve this purpose, two theories, namely Transactional distance and Connectivism were coined together with the Technological Pedagogical Content Knowledge (TPACK) framework to underpin the study. The philosophical worldview is pragmatism having employed mixed method. Participants in this study were 145 students who registered a year programme for two modules in the Bachelor of Education (B.Ed.) programme at a Higher Education institution were surveyed to collect the quantitative data. Data from the face-to-face semi-structured interviews were collected with five e-tutors from the research sites. Online observations data were collected from the e-tutor sites of the institution’s learning management system (LMS). The results suggest that e tutors still lack the technology knowledge in order to deliver the content aimed for the design process in an ODeL environment. Also, it was evidenced that the e-tutors have not acquired pedagogical strategies for driving the pedagogy for the design process in an ideal context of ODeL. It should also be borne in mind that findings for the content knowledge indicated that the e-tutors still lack the knowledge for exploiting content knowledge of the design process to suit an ODeL environment. These findings highlight a need for technology to support e tutors’ pedagogical strategies towards a meaningful understanding of the design process and its implications across ODeL contexts. / Ketsahalo ea Open Distance le e-Learning e ntlafalitse litsi tsa thuto e phahameng bakeng sa baithuti ho fihlella taeo nako efe kapa efe le kae kapa kae.
