1. [No author]. A study of the influence of common tasks for assessment on the pedagogical practices of grade nine natural science teachers.

Degree: Education, 2009, University of KwaZulu-Natal

This study explores the influence of Common Tasks for Assessment (CTAs) on the pedagogical practices of Grade 9 Natural Science teachers. CTAs are assessment tasks set by the National Department of Education and administered as an external examination in Grade 9 classes (exit level I) in South Africa. The pedagogical practices in this case refer to the strategies the teachers employ in their practices and the work they give to the learners. The key research questions are: I . What are the teachers' views on the CTAs as teaching and learning tools? 2. What influence do CTAs have on the pedagogical practices of Grade 9 Natural Science teachers? I followed an interpretive paradigm in my research. I used both quantitative and qualitative approaches in my study, so I used triangulation. This study involves survey research hence survey strategies are used. Initially quantitative approach are used and then followed up by qualitative approach. Questionnaires are used to facilitate the quantitative approach and interviews are used for qualitative approach. Thirty two participants responded positively to questionnaires, and five teachers were interviewed in this research. Questionnaires were set to determine the influence of CTAs on teachers' pedagogical practices and interviews were set to validate or corroborate what transpired in questionnaires and also to find the views of teachers on CTAs. The analysis of the questionnaires showed that about 84% of teachers were influenced by CTAs. It also revealed that group work, problem solving, pupils' presentations, self assessment, practical work and investigations are the categories of work that are influenced the most by CTAs. The analysis of the interviews also had the same findings. The interviews also revealed that the inquiry learning, self discovery and question and answer are teaching methods promoted by CTAs. The research also found that some teachers view CTAs as good tools for improving teaching and learning in South African schools because they promote critical thinking and problem solving. After analyzing the results I came to the conclusion that CTAs promote learner-centred pedagogical practices in teachers. They also accentuate the strategies that are associated with critical thinking and problem solving. I also concluded that CTAs tend to influence the teachers towards attaining quality education because leaner-centred practices and problem solving are the key components of quality education. This study has also found that teachers are not happy with the manner in which CTAs are administered. A possible further study therefore could be that of investigating the ways in which the administration of CTAs can be improved so that they can be more beneficial to teaching and learning in South Africa.

2. [No author]. Investigating the potential of a classification algorithm to identify black wattle (Acacia mearnsii De Wild.) tress using imaging spectroscopy.

Degree: Environmental science, 2013, University of KwaZulu-Natal

In South Africa, invasive black wattle trees (Acacia mearnsii D. Wild) are a major threat to ecosystem functionality causing widespread social, economic and environmental degradation. It is important that environmental managers are provided with rapid, regular and accurate information on the location of invasive black wattle trees to coordinate removal efforts. This study investigated the potential of an automated image classification algorithm to accurately identify black wattle (A. mearnsii De Wild.) trees using imaging spectroscopy. Hyperspectral data acquired by the EO-1 Hyperion sensor was used to identify black wattle trees in two study areas near Greytown, KwaZulu-Natal, South Africa. Image classifications were performed by the classification algorithm to identify black wattle trees using general and age specific spectral signatures (three to five years, seven to nine years, eleven to thirteen years). Results showed that using the general spectral signature an overall accuracy of 86.25% (user’s accuracy: 72.50%) and 84.50% (user’s accuracy: 69%) was achieved for study area one and study area two respectively. Using age specific spectral signatures, black wattle trees between three to five years of age were mapped with an overall accuracy of 62% (user’s accuracy: 24%) and 74.50% (user’s accuracy: 49%) for study area one and study area two respectively. The low user’s accuracies for the age specific classifications could be attributed to the use of relatively low resolution satellite imagery and not the efficacy of the classification algorithm. It was concluded that the classification algorithm could be used to identify black wattle trees using imaging spectroscopy with a high degree of accuracy.

3. Mudaly, Thinasagree. An analysis of approaches for developing national health information systems : a case study of two sub-Saharan African countries.

Degree: 2016, University of KwaZulu-Natal

Health information systems in sub-Saharan African countries are currently characterized by significant fragmentation, duplication and limited interoperability. Incorporating these disparate systems into a coherent national health information system has the potential to improve operational efficiencies, decision-making and planning across the health sector. In a recent study, Coiera analysed several mature national health information systems in high income countries and categorised a topology of the approaches for building them as: top-down, bottom-up or middle-out. Coeria gave compelling arguments for countries to adopt a middle-out approach. Building national health information systems in sub-Saharan African countries pose unique and complex challenges due to the substantial difference between the socio-economic, political and health landscapes of these countries and high income countries. Coiera’s analysis did not consider the unique challenges faced by sub-Saharan African countries in building their systems. Furthermore, there is currently no framework for analysing high-level approaches for building NHIS. This makes it difficult to establish the benefits and applicability of Coiera’s analysis for building NHIS in sub-Saharan African countries. The aim of this research was to develop and apply such a framework to determine which approach in Coiera’s topology, if any, showed signs of being the most sustainable approach for building effective national health information systems in sub-Saharan African countries. The framework was developed through a literature analysis and validated by applying it in case studies of the development of national health information systems in South Africa and Rwanda. The result of applying the framework to the case studies was a synthesis of the current evolution of these systems, and an assessment of how well each approach in Coiera’s topology supports key considerations for building them in typical sub-Saharan African countries. The study highlights the value of the framework for analysing sub-Saharan African countries in terms of Coiera’s topology, and concludes that, given the peculiar nature and evolution of national health information systems in sub-Saharan African countries, a middle-out approach can contribute significantly to building effective and sustainable systems in these countries, but its application in sub-Saharan African countries will differ significantly from its application in high income countries.
