- Description: Communication with an organisation’s customers has become one of the most important factors that play a role in doing business today. Organisations that supply their customers with correct and different kinds of information create customer loyalty. Dairy farmers are no exception to the rule, because of the ongoing planning that dairy farmers need to do on a daily basis. Dairy farming in South Africa is extremely price sensitive and therefore information that can help in decision making plays an important role in making the right decision at the right time. The Internet has become an essential environment where information is readily available to anyone who has access to the technologies, such as smartphones, computers and tablets. Thus, it will be beneficial for both the organisation and the dairy farmer to have relevant information available on the organisation’s website. The information that is made available to the dairy farmers on these websites needs to be updated on a daily basis. The information must be relevant to dairy farming and must provide additional information besides the information that the specific organisation specialises in. Information as a Service (IaaS) for Dairy Farmers in South Africa is the focus of this research. The purpose of the investigation is to provide a means of providing the information needed by dairy farmers in South Africa, to enable them to make the right decisions on an operational level. The empirical data were collected, analysed and interpreted. From these findings a proposed communications framework is created to assist organisations to better communicate with dairy farmers in South Africa. The purpose of this research study is to design a framework which will provide IaaS to dairy farmers in South Africa. The research determined the different ways in which organisations can communicate with dairy farmers and the best time period in which that communication should take place for each specific communication strategy. Therefore, the aim of the research study was to determine the best ways to communicate with dairy farmers. A clear knowledge of the technologies that dairy farmers use to manage information was determined by the research study. The required information that dairy farmers need to make the correct decisions suitable for the requirement of farming on a practical level was determined by the research study.The proposed framework on Information as a Service for Dairy Farmers could help organisations to supply dairy farmers with the right information at the right time. The proposed framework will assist organisations dealing with dairy farmers easier and will also assist farmers, because the information provided as a service will be relevant to dairy farming. The treatise is an exploratory, mixed method research study which consists of literature reviews, surveys and cross-sectional studies. Secondary resources was used to conduct literature studies to determine the information needed by dairy farmers. A questionnaire was compiled from existing questionnaires as well as from literature studies and was completed by the respective respondents in the dairy farming community. The survey also consists of questions that determine what dairy farmers think about the service they receive from the organisations that they deal with. A cross-sectional study was used to compare the information needed specifically by pasture-based dairy farmers in relation to total mixed-ration-based dairy farmers. Both Descriptive and Inferential Statistical methods will be used for the analysis of the data. The communication systems can vary from Self-Help Groups to Mobile Technology. The type of communication system will depend on the systems that the organisation have available for their customers. The timing of communication with dairy farmers needs to be convenient and depends, according to literature, on the type of social networking that the organisation might use. An organisation that deals with dairy farmers needs to decide which Social Media site is most suitable when it needs to communicate with dairy farmers. The technology used to access information consist of Laptops, Smart Phones, Tablets and Desktops. Agricultural organisations provide information which dairy farmers need, to give them the correct guidance in performing good farming practices in order to produce safe, high-quality milk. The study will conclude with the development of a proposed communications framework where agricultural organisations can provide information as a service to dairy farmers.

- Description: Worldwide, there is a decline in interest in the computer science profession and in the subject at secondary school level. Novice programmers struggle to understand introductory programming concepts and this difficulty of learning to program is contributing to the lack of interest in the field of computer science. Information Technology (IT) learners in South African secondary schools are novice programmers, introduced to introductory programming concepts in the subject which also includes topics on hardware and system software, e-communication, social and ethical issues, spreadsheets and databases. The difficulties faced by IT learners are worsened by the lack of suitably qualified teachers, a saturated learning programme that allocates very little time to the understanding of complex programming concepts and limited class time where practical examples can be implemented with the support of the IT teacher. This research proposes that IT learners could be supported by a programming assistance tool (PAT). A PAT is a software program that can be used by novice programmers to learn how to program and/or improve their understanding of programming concepts. PATs use different techniques to assist novice programmers. The main objective of this research was to determine whether the use of a PAT impacted IT learners’ understanding of programming concepts and motivation towards programming. The literature study and feedback from IT learners and teachers were used to identify novice programming difficulties and IT learner programming difficulties, respectively. Selection criteria were derived from the programming difficulties identified. The selection criteria were grouped into three categories, namely, programming concepts, programming knowledge and programming skills. Existing PATs were evaluated using the selection criteria and three PATs, namely, RoboMind, Scratch and B#, were selected as suitable for use by IT learners. RoboMind was adapted in this research study, allowing it to support the Delphi programming language. The three PATs were evaluated by participating IT learners at four schools. The findings of this research provided no conclusive evidence that IT learners who used a PAT had a significantly better understanding of programming concepts and motivation towards programming than learners who did not use a PAT. IT learner feedback was used to identify the strengths and shortcomings of the three PATs and to provide recommendations for the development of PATs specifically to support IT learners. This research study has provided several theoretical and practical contributions, including the research design, selection criteria, adaptations to RoboMind and the evaluation of the three PATs. In addition, IT teachers and learners have been made aware of PATs and the support that can be provided by these PATs. IT teachers have also been provided with a means of selecting PATs applicable to the IT curriculum. All the research contributions have formed the basis for future work, such as improving and extending RoboMind’s functionality and support of programming concepts, the refinement of the selection criteria and, ultimately, the development of a new PAT, specifically designed to support IT learner understanding of programming concepts and motivation towards programming.
