However, teaching and learning computer-programming concepts and skills have been recognised as a great challenge for both teachers and students, for many reasons. Computer-programming requires new ideas in thinking and conceptualising practical solutions. It requires creative skills in solving practical, but often difficult problems. Moreover, computer-programming students, generally lack problem-solving skills and self-efficacy. They typically find it difficult to use artificial programming languages to solve challenging problems. There is the problem of poor background in science and mathematics that would help students to rapidly understand the intricacies of computer-programming. Students are not motivated to overcome the fear of the bizarre syntax of computer-programming codes. These challenges, coupled with the huge potential of computing applications in the society have made the development of effective pedagogies and environments for computer-programming courses, an important issue. To address this issue in a unique way, this study proposes to explore a web-based, blended learning technique with minimal instructor intervention, to improve the computer-programming competence of information technology students. These students are expected to have developed an acceptable level of computer-programming competence at university to be job ready and to be self-reliant in their future careers. The technique being proposed in this study was implemented in a blackboard ™/®/© web-based environment. The effectiveness of the technique was demonstrated using experimentation coupled with the data analysis method that is based on the three-parameter item response theory and retrospective pretest. The method used in this study to evaluate computer- programming competence of students reflects the perspective of the students in the evaluation process. The results of the study indeed show that using the proposed technique, information technology students dynamically collaborate with their peers with minimal instructor intervention towards improving their computer-programming competence. / M

ICTs have had a tremendous impact on our educational environment. There have been a huge number of developments and support in implementation of ICT in Higher Education teaching and learning, also referred to as e-learning. Similarly there appears to be quite a number of research conducted on the use of ICTs in blended learning settings worldwide and as well as in South Africa. Very little research however, has focussed on the experiences of lecturers with e-learning, specifically as it relates to Learning Management Systems (LMS). In trying to meet the requirements of its academic programmes and be in line with new developments worldwide, the University which is the focus of this study pilot projected the use of an LMS in a blended learning approach which integrates face-to-face classes with Blackboard, an ICT-based system or tool. Following the implementation of the pilot project, this study explores the experiences of lecturers in their blended learning environments at this university in the Eastern Cape province of South Africa. The research design was that of an interpretative paradigm within a qualitative research approach in a case study methodology. Purposive sampling of six lecturers from departments within faculties across two campuses was done. The data was gathered through interviews, a follow-up questionnaire and document analysis was employed. Using Critical and Social Realism as meta-theories the study employed aspects of Activity Theory as substantive theory to understand particular experiences of blended learning environments and identify conditions which enable and constrain engagement in these environments so as to explore potential lessons to inform the kind of educational support which could be offered to facilitate uptake of the LMS.

The study investigates the problem of applying Information Communication Technologies (ICTs1) in education in the context of KwaZulu-Natal. The first part of the study reviews theories and literature relevant to understanding and defining e-education and the nature and scope of e-education worldwide. Subsequent chapters describe the construction of a survey instrument employed to measure and evaluate the extent of e-education in KwaZulu Natal, and the findings of the survey. Penultimate chapters blend the insights gained from this literature review to interpret the results, obtained through the quantitative research methodology, to describe a set of conclusions and recommendations in the context of applying Information Communication Technologies in the formal learning environment in KwaZulu-Natal.

Submitted in fulfillment of the requirements of the degree of Masters of Technology: Information Technology, Durban University of Technology. Durban. South Africa, 2015. / Information and Communication Technologies (ICTs) are ubiquitous nowadays, and there are many situations where they are overall perceived either as advantageous or as disadvantageous; but there are other situations where it is unknown whether they are overall advantageous or disadvantageous. For example, ICTs are perceived as advantageous for communication, but texting during driving is perceived as worse than drinking while driving. Concerning for example eLearning which is the use of ICTs in education, the fact that it has not yet eliminated the problem of poor academic performance raises the question as to whether ICTs are advantageous or not in education especially when one considers their high cost. Therefore, the aim of this study is to examine the perceptions of educators on the advantages and disadvantages of eLearning. This aim will be subdivided into three types of research objectives: (a) to select from existing literature suitable theories that can be applied to the examination of educators’ perceptions on the advantages and disadvantages of eLearning; (b) to design a model of the factors affecting educators’ perceptions on the advantages and disadvantages of eLearning; (c) to empirically test the above announced model; (d) to propose recommendations on how to optimize the impact of eLearning. Objectives a, b, and d were accomplished through the review of existing appropriate literature on teaching and learning, and on eLearning; but objective c was met through a survey of 65 educators of Camperdown town schools in the Pinetown district of KwaZulu-Natal province of South Africa. The outcomes of these four objectives are as follows: (a) Constructivism, Progressivism, and Self-regulated learning can be used as suitable theories applicable to the examination of educators perceptions on the advantages and disadvantages of eLearning; (b) It makes sense to hypothesize that educators perceptions on the advantages and disadvantages of eLearning are affected by their demographics and by their adherence to learning theories; (c) Empirical test conducted by this study confirm that educators perceptions on the advantages and disadvantages of eLearning are affected by their adherence to constructivism and to progressivism; (d) It can be concluded that the impact of the use of ICTs on teaching and learning will be optimized through the deployment of constructivist and progressivist educators as champions of eLearning projects in schools.

Submitted in fulfillment of the requirements for the degree of Master of Technology: Information Technology, Durban University of Technology, Durban, South Africa, 2015. / The use of mobile devices such as cell phones, smartphones, personal digital assistants and tablet computers is becoming prevalent in today’s world; and it is facilitating access to a vast amount of data, services and applications for the improvement of people’s lives. Advances in electronics and manufacturing technologies usually lead to the rapid release of newer and sleeker models with new features and capabilities. These newer models therefore render older models obsolete, and this pushes people to frequently replace their devices. The drawback of such frequent replacements is that a large number of devices are disposed and they end up as e-waste. The fact that e-waste constitutes a major hazard to human health and to the environment is the motivation behind this study whose aim is to examine the factors affecting the perceptions of teachers on the durability of cell phones in the e-learning context. This research aims was achieved through the content analysis of existing literature and through a survey of 67 secondary school teachers from the iLembe and UMgungundlovu district municipalities in the KwaZulu-Natal province of South Africa. The attribution theory was selected as the theoretical framework for this study, and it led to the identification of four independent variables (Demographics, Intention, Knowledge, and Actual use) and of one dependent variable (Perceived Durability). The results of this study indicate that teaching experience and school location are the only two demographics that affect other variables from this research: School location affects cell phone durability, and teaching experience affects cell phone usage intentions. These results also indicate that all the variables of this research are linked except for the relationship between knowledge and perceived durability. One of the recommendations of this study is the proposal of a three year cycle for cell phone renewals in schools mobile learning projects in order to manage e-waste through e-recycling, and this recommendation is based on the finding of this research that teachers believe that cell phones generally lasts between two to three years. The main contribution of this study is to have examined the durability of mobile phones in the e-learning context and this is something new compared to all the studies reviewed by this research.

This case study attempts to explain the implementation of Information Communications Technology (ICT) in primary schools, specifically mentioning the integration of computers into the curriculum. To begin with, the implementation of ICT from an international perspective is explored and subsequently some international and African ICT policies in education are also identified and discussed. Nationally, ICT policies from four provinces in South Africa are examined and analyzed. Provincially, the ICT Projects Coordinator in the Eastern Cape Department of Education (ECDoE) was interviewed to obtain a provincial perspective of ICT in the Eastern Cape. From local schools’ perspective, four primary schools and one secondary school in the Makana and Somerset East Districts were visited and the ICT coordinators at these schools were interviewed. The results reveal that the previously disadvantaged (PD) schools were not utilizing their computers effectively. This is due to a number of factors, including a lack of funds to maintain the computers; unskilled or under skilled teachers in ICT; and under resourced computer facilities. The previously advantaged (PA) schools, on the other hand, have well-resourced computer laboratories, adequate maintenance plans as well as skilled teachers in ICT that enable these schools to effectively integrate the use of computers into the curriculum. Key words: Information communications technology, implementation, integration, previously advantaged, previously disadvantaged, curriculum, primary school, secondary school.

Information and Communication Technologies (ICTs) are capable of expanding access to quality education, educational resources, and also provide teachers with new skills. Nevertheless, a majority of rural public schools have limited ICTs, mainly due to geographical landscape, lack of service delivery and poverty. As a result, they currently seem not to be adequately benefiting from current advancements in ICTs. The main objective of this research study was to investigate an appropriate broadband services delivery model using wireless access technologies, such as a Global System for Mobile communication (GSM) and Enhanced data rates for GSM Evolution (EDGE) to deliver electronic-based educational information to resource-constrained public high schools. An exploratory case study approach was adopted to identify and understand the challenges faced by rural schools in the Greater Tubatse Municipality (GTM), including educational services and content considered by the schools as relevant and useful. The research results indicate that resource-constrained schools in the GTM are facing challenges of lack of access to electronic educational information and services, and as a result, teaching and learning becomes limiting and challenging. Based on the research findings, the results show that having access to learning material via electronic platforms could afford educators and learners the opportunity to interact with the outside world, improve learning and teaching and benefit the community as a whole. The broadband services delivery conceptual model (BSDCM) was proposed, developed and evaluated to address the lack of electronic educational information and services for resource-constrained public high schools. The BSDCM is composed of both technical and non-technical components that consider requirements of all role players, ICT challenges, policy makers and Information Communication Technology for Education (ICT4ED) interventions. The proposed model addressed some of the challenges regarding lack of access to educational content. However, it is recommended that the ICT4ED policies governing the use of mobile devices in the classrooms be introduced by the relevant authorities. In addition, a comparative analysis of other network technologies should be conducted to establish if the TCP/IP header compression on Point to Point Protocol (PPP) improves the performance of the network in resource-constrained environments. Furthermore, it is recommended that further research and experiments be conducted to determine if other various third party content providers could create and deploy various educational services and content for different computing platforms using the proposed BSDCM. / School of Computing / M.

M.Ed. (Information and Communication Technologies in Education) / The use of ICT at all levels in the schools has been shown to have a positive impact on teaching and learning, in particular of Mathematics. In South Africa, Dinaledi schools have been given ICT resources by the former Department of Education (South Africa) with the aim of improving Grade 12 results, particularly in Mathematics. This study aims to assess the use of ICT for learning in the selected Dinaledi School, with an additional focus on Mathematics learning in grade 8 to 12, and to provide guidelines for the use of ICT in the Dinaledi schools, and specifically to support Mathematics learning. The ‘mixed–method’ study comprised several sets of data, both quantitative and qualitative, using a sequential-mixed-method-explanatory design for the case of the selected Dinaledi School, Kone High School (Fictitious name), situated in the Limpopo Province, to determine how ICT resources are used in the teaching and learning, and also for Mathematics. In the quantitative phase, quantitative data was collected by means of structured questionnaires on the use of ICT from the principal, teachers and students. The University of Johannesburg’s STATKON unit analysed the data, and confirmed the latent theoretical constructs that were embedded in the questionnaire. To clarify the results, in the follow-up qualitative phase, the principal, teachers and students were interviewed on the use of computers. Other quantitative data were sourced from official end-of-year matric results. Both teachers and students pointed that the ICT resources were not sufficiently used in teaching and learning, in particular for Mathematics, although in contrast it appeared that the principal believed that the ICT resources were sufficiently used for teaching and learning. The study concluded that ICT was not an important driver of teaching and learning in this Dinaledi school and it did not play the role in teaching and learning at Kone High School, as is envisioned for Dinaledi schools.

Thesis (Ph. D. (Administration)) -- University of Limpopo, 2016 / The thesis drew from a combination of phenomenology, interactionism and critical theories because South Africa in itself consists of a polity with national dynamics, within the matrices of globality in which connectivity plays a determining role, especially in terms of the capacity to competitively participate in the global knowledge economy. Guided by reading collectively and critically from the economic, physical development, policy analysis, interpretative as well as collaboration planning approaches, among others, and the mono-centric, multilevel and adaptive models of governance, the thesis constructed a conceptual argument that the primate enablers for modernized infrastructure, skills and culture attached to the preconditions for blended pedagogies, are modernized planning and governance. However, the attainment of planning, governance, infrastructure and skills is in itself inadequate to inculcate the culture necessary for the integration of elearning with conventional didactics. This observation is confirmed through international experiences that involve the developed countries that are in the very high and high Human Development Index (HDI) categories such as Australia, Poland and Korea as well as Thailand, Brazil and Algeria, respectively, where the presence of planning, governance, infrastructure and skills has not automatically precipitated a culture required for blended pedagogies. This evidence does not seek to underplay the significance of planning, governance, infrastructure and skills in the integration of e-learning with conventional didactics, but the thesis has established that the existence of modernized planning, governance, infrastructure and skills are a necessary, rather than a sufficient, condition. From the literature review, the thesis deduces that e-culture is a virtually sufficient condition for the establishment of blended pedagogies. Hence, variables such as GDP per Capita, Gross Fixed Capital Formation, Average Annual Growth of General Government Final Consumption Expenditure, Research and Development Expenditure and Public Expenditure on Education, that demonstrate the level of human development of a country, do not necessarily reflect capacity to enable the establishment of blended pedagogies. Such conditions do not always coexist with pre-eminence of communication using Internet and/or Mobile Phones, characteristic of the “Net Generation Culture”. The vi latter, as a specific form of e-culture, is heavily dependent on infrastructure and skills which are, among others things, reflected in Gross Fixed Capital Formation, Employment to Population Ratio, Labour Force Participation Rate, Labour Force with Tertiary Education, Total Electrification Rate as well as Employment to Population Ratio. The observation made above is corroborated by the experiences of developing countries such as Vietnam, Zambia and Kenya, which are in the medium and low HDI categories, wherein the absence of appropriate and adequate infrastructure, skills and e-culture together with planning and governance imperil the evolution of the national culture into that of the “Net Natives”. From an empirical perspective, consistent with the hybridization of philosophy, the thesis conveniently selected a target population that consisted of a total of 15 countries, wherein 14 of these observations provide a backdrop against which South Africa’s relative readiness and appropriateness of planning, governance, infrastructure, culture and skills for blended pedagogies are determined. A combination of purposive and quota sampling procedures was adopted to select the 15 countries across the four HDI categories. The 15 countries are classified in terms of the 2015 United Nations Development Programme HDI conceptions, which produced four levels of “very high”, “high”, “medium” and “low”. A total of 28 variables were selected for Principal Component Analysis (PCA). The thesis used secondary data sources for textual and empirical data, where the latter was largely drawn from the United Nations Development Programme Reports. The textual data were analysed qualitatively through thorough descriptions, classification and drawing of connections, the statistical data were organized into a 15 (observations) by 28 (variables) raw data matrix and analysed through the PCA. Verbal tools were used to provide thick descriptions of contexts regarding historical, social, demographic and economic backgrounds in order to situate the motive underlying the planning and governance of blending e-learning pedagogies with conventional didactics in South Africa. From a quantitative perspective, PCA was used for statistical modelling that standardized the data and produced a variety of useful statistical summaries such as Principal Components, Eigenvalues, Communalities, Correlation Matrix, Component Loadings, Component Scores and Scattergrams. vii Given that the raw data consisted of 15 observations by 28 variables, a 28 by 28 variables correlation matrix was generated. Of the 378 correlations that the thesis discovered, 183 are direct and 195 are indirect. However, 276 of the 378 relationships are negligible; only 102 correlations were strong and significant enough to deserve closer examination. Principal Component Analysis extracted a total of 15 Principal Components; and, the first seven according to the thesis, accounted for the cumulative percentage of 92% in the interrelationships. Furthermore, it is evident that Principal Component 1 consists of the characteristics of Modernized, Planning, Governance, Infrastructure, Skills and Culture, which are diametrically different from the Frustrated Development, Unsustainable State Intervention and Societal Inequalities, Limiting e-infrastructure, e-skills Constraint, Muted Development Potential and the Non-existent e-culture that are associated with the rest. Given the significance and strength of the eigenvalue and component loadings on Principal Component (PC) 1, it should signify the presence of enabling environments for e-infrastructure, e-governance, e-culture and e-skills consistent with modernized planning and governance of blended pedagogies. Therefore, a country that scores negatively on PC 1 and positively on PC 2 would represent a society that is far less prepared for blended pedagogies where an unrelenting state investment for e-infrastructure, e-governance, eskills and e-culture would translate into a replacement behaviour rather than integration of conventional didactics with digital technologies. This infers that the status of governance, infrastructure, skills and culture would remain less optimal for the adoption of blended pedagogies. For such countries, investing heavily in blended pedagogies without first creating the requisite conditions for engagement in the global knowledge economy would imply that they would have sought to exploit non-existent capacity in governance, infrastructure, skills and culture. South Africa's component score on PC 1 is -0.58, which would in terms of the analysis mean that this country lacks the character of modernized planning, governance, infrastructure, skills and culture that are necessary for engendering blended pedagogies. Countries such as Norway, Australia, Poland, Korea, Thailand, Vietnam and Sri Lanka that have variably trotted the blended pedagogies score positively on PC 1. Besides, viii some of these countries have not been successful in blended pedagogies, notwithstanding their apparent enabling environments. Conversely, South Africa's component score on PC 2 is extraordinarily higher than all of the 14 countries; and, it is 2.15 points higher than the nearest score. It is important to recognize that South Africa's score on PC 2 is an extreme case and a virtual outlier that has no connection to the rest of the fourteen countries, especially those in the Medium and Low HDI. Overall, South Africa's component scores highlight the relative dearth of appropriate planning, governance, infrastructure, skills and culture, that are necessary for the adoption of blended pedagogies. Whereas the thesis finds that there is no direct correlation between the level of human development and adoption of blended pedagogies, the latter appears to be a result of convoluted processes that involve the creation of enablers for e-culture largely through planning, governance, infrastructure, skills and culture. These qualities are embedded with societal equality, equity of access to services, capital formation, employment, education as well as Internet infrastructure. The thesis therefore, concludes that South Africa's potential for human development is derailed through endless planning that has become an end in itself. Planning for its own sake, which defines South Africa's democratic history, means that modernized governance, skills and e-culture that are necessary for blended pedagogies have remained substandard. The thesis establishes that South Africa’s national as well as Information and Communication Technology (ICT) planning demonstrates ambition and interest, which is however pursued in the absence of effective governance of implementation and adoption of appropriate educational technologies. Evidently, South Africa is yet to attain modernized planning, governance, skills and culture appropriate for the implementation of blended pedagogies, notwithstanding the infrastructure provided in some of the schools for teaching and learning. Instead, South Africa’s pedagogic digital transformation is characterized by replacement of conventional didactics with e-learning rather than integration for blended pedagogies. Therefore, this evidence suggests that, although South Africa’s educational ICT infrastructure seems to be relatively modernized, the absence of appropriate and adequate planning, governance, skills and e-culture impairs the successful implementation of blended learning. The thesis, therefore, recommends ix that adoption of blended pedagogies should be supported through the creation of eculture in households, underwritten by modernized planning, governance, infrastructure and skills for competitive participation in the global knowledge economy.

This study reports on the use of action research methodology to generate a critical reflective collaborative setting. The aim was to infuse the institution with the results of this study in order to stimulate debate on the issues regarding change in practice and systems. The suitability of Internet communication technologies, more specifically the online learning community, is evaluated as a delivery mode that would address today’s learning needs. This required the collaborative construction of knowledge in a community setting with the teacher enabling communication and interaction, and facilitating and stimulating the sharing and testing of ideas and constructs. But such a learning scenario was found to be significantly challenging to the current print-based learning experience. It implied a challenge to teaching and support staff as well as the questioning of the efficiency and legitimacy of current instructional design staff and procedures used. The teaching responsibilities and commitment in the online community was outlined as against current print-based teaching practice. The current development and production culture, which restricts innovation and change in practice and systems significantly, came under pressure. The success of the online learning community in the Unisa context was nevertheless significant and it has the potential to serve as an opportunity to re-examine print-based production and delivery and to devise strategies and solutions to increase the quality significantly. / Faculty of Education / D.
