- Description: The main research problem addressed in this study is that South African cities are not effectively integrating and utilising available, and rapidly emerging smart city data sources for planning and management. To this end, it was proposed that a predictive model, that assimilates data from traditionally isolated management silos, could be developed for prediction and simulation at the system-of-systems level. As proof of concept, the study focused on only one aspect of smart cities, namely crime management. Subsequently, the main objective of this study was to develop and evaluate a predictive model for crime management in smart cities that effectively integrated data from traditionally isolated management silos. The Design Science Research process was followed to develop and evaluate a prototype model. The practical contributions of this study was the development of a prototype model for integrated decision-making in smart cities, and the associated guidelines for the implementation of the developed modelling approach within the South African IDP context. Theoretically, this work contributed towards the development of a modelling paradigm for effective integrated decision-making in smart cities. This work also contributed towards developing strategic-level predictive policing tools aimed at proactively meeting community needs, and contributed to the body of knowledge regarding complex systems modelling.

- Description: The National Agricultural Advisory Services (NAADS) programme was formed in Uganda in 2001 as a response to previously poor performance of extension services in Uganda. NAADS was formed as a demand-driven extension programme designed to improve farmers’ incomes through increased farm output in agriculture and to solve food insecurity in the country. Given the enormous resources injected into the programme intended to improve the welfare of farmers, the main objective of this study was to determine the economic viability of NAADS throughout the period 2001-2017. The study was conducted in four districts: Mpigi, Mubende, Luwero, and Mukono. Using a non-probability random sampling technique based on convenience and snowball sampling techniques, a sample of 384 participants took part in this study. Cost-Benefit Analysis (CBA) was used to assess the merits of this public investment project. The study also used descriptive methods of analysis such as a 5-point Likert-type scale so as to derive means. In addition, the study practiced the Principal Component Analysis (PCA) technique, and the cronbach alpha coefficient was used to test the reliability of factors in explaining the concerned five dimensions of this study.

Teachers’use of curriculum materials in Grade 3 Mathematics: A Case Study

- Description: The study examines four curriculum documents with regards to curriculum facets, further interrogated through indicators for certain facets in order to ascertain whether the documents could be considered to be educative. Comparison is made with selected resources internationally. Observed episodes in four mathematics classes are interrogated with regards to teacher facets and concomitant indicators, to assess whether the tenets proposed in the written curriculum are translated into practice in the classrooms. The four Grade 3 teachers are interviewed about their views on the curriculum, their views on teaching and their views on their own agency in teaching mathematics. The teachers’ complete selected examples from a Mathematics Knowledge for Training (MKT) questionnaire and are engaged in conversations about iii their beliefs about mathematics and their confidence in both doing and teaching mathematics. The study identifies that the current CAPS curriculum documents focus on mathematical content almost exclusively and give minimal guidance concerning pedagogical content knowledge. The agency of teachers is not addressed. The study suggests a three-dimensional model of curriculum design that encompasses new educative curriculum materials; guidance on innovative teacher practices and direction towards new beliefs in teachers which could build agency and confidence. The concern that this study uncovers is that although the school and teachers were specifically chosen to minimise linguistic and social detractors, the intended curriculum does not appear to have been universally translated into
