D.Phil. (Engineering Management) / Process improvement is essential for an organisation to remain competitive in the global market. Regardless of the type of products or service being rendered, such improvement is essential for remaining profitable and staying at the top of one’s industry market. The Lean Six Sigma (LSS) methodology is a preferred methodology for continuously improving business processes, thereby improving profitability and increasing market share. Higher education institutions are increasingly being placed under pressure to improve throughput and to ensure that that their institutions are sustainable. This focus on higher education inefficiencies has resulted in institutions looking for new ways to improve processes which will lead to increases in throughput. In this study, a LSS framework has been developed and applied for improving engineering education processes...

The mind and character of an individual can be fostered by the subjects which have proved themselves to be of value in improving the education of man, not only from scientific, but also from moral and aesthetic stand points. The question is whether or not geography as a subject fulfils this requirement. For this it must have a distinctiveness of aim and a limitation of content. Civilization today is passing through great crises. Wars, rumours of wars, cold wars, economic crises, exhaustion of natural resources etc. are reported daily in the newspapers. Education of a certain type is needed - an education which will develop in man a deep concern for the freedom and good life of his fellows, and some understarding of the major problems of the world and possible solutions. Man is no longer a unit of a small self-contained community, but has his responsibilities as a citizen, firstly of his own country and secondly of a world community. Upon his solutions to the problems of the world depend to some degree the progress and development of his town, country, of the world generally. Education therefore ought to train the child to take his place in the world, not only as a man, but as a citizen. Children must be taught to think and reason for themselves. Geography as a subject lends itself magnificently to the general education of men and the development of good citizens. Geography can help to teach pupils to understand and experience the adult world. South Africans are fortunate in that geography is a compulsory subject up to standard seven. In high school beyond this level it is not offered by all schools.

Magister Commercii - MCom / This study explored the provision of entrepreneurship education at higher education institutions in Rwanda with special reference to the levels of provision, support mechanisms, course objectives, contents, teaching and assessment methods to ascertain whether they are appropriately developed to prepare students for entrepreneurship as a career option. / South Africa

Philosophiae Doctor - PhD / The purpose of this study was to investigate the views of students and lecturers at the University of Namibia about teaching and learning. The study specifically determined the views of students and lectures in relation to language, teaching, learning and assessment as well as what we might learn from analysis of these views to assist in improving teaching, learning and assessment. / South Africa

Philosophiae Doctor - PhD / The purpose of this study was to investigate the epistemological obstacles that mathematics students at undergraduate level encounter in coming to understand the limit concept. The role played by language and symbolism in understanding the limit concept was also investigated. A group of mathematics students at undergraduate level at the National University of Lesotho (NUL) was used as the sample for the study. Empirical data were collected by using interviews and questionnaires. These data were analysed using both the APOS framework and a semiotic perspective. Within the APOS framework, the pieces of knowledge that have to be constructed in coming to understand the limit concept are actions, processes and objects. Actions are interiorised into processes and processes are encapsulated into objects. The conceptual structure is called a schema. In investigating the idea of limit within the context of a function some main epistemological obstacles that were encountered when actions were interiorised into processes are over-generalising and taking the limit value as the function value. For example, in finding the limit value L for f(x) as x tends to 0, 46 subjects out of 251 subjects said that they would calculate f(0) as the limit value. This method is appropriate for calculating the limit values for continuous functions. However, in this case, the method is generalised to all the functions. When these subjects encounter situations in which the functional value is equal to the limit value, they take the two to be the same. However, the two are different entities conceptually. / South Africa

Magister Scientiae - MSc / Over the last few years it became clear that the students struggle with the basic concepts of logarithms and inequalities, let alone logarithmic inequalities due to the lack of exposure of these concepts at high school. In order to fully comprehend logarithmic inequalities, a good understanding of the logarithmic graph is important. Thus, the opportunity was seen to change the method of instruction by introducing the graphical method to solve logarithmic inequalities. It was decided to use an mathematical software program, Omnigraph, in this research. / South Africa

The purposes of the study were: (1) to determine the effects of four testing strategies upon performance in college algebra, attitude towards mathematics, and attrition rate; (2) to determine the effects of two types of frequent testing upon performance, attitude, and attrition rate, (3) to determine the effects of different frequencies of in-class testing upon performance, attitude, and attrition rate; and (4) to draw conclusions which might help in selecting testing methods for college algebra classes.

An increased emphasis is being placed on ethics in Information Systems. An investigation of: the relevant literature which highlighted the growth of, and importance in understanding the moral philosophies which underlie Computer Ethics; and the official curricula recommendations that have increasingly and consistently recommended inclusion of courses describing the Social, Professional and Ethical responsibilities of Information Systems Professionals; and informed by the observations from two empirical Studies that showed the extent of unethical behaviour, and how this behaviour is diminished in those who have received formal tertiary level education resulted in a proposed new course module on Ethics in Information Systems. The module follows a sandwich-approach whereby two stand-alone modules are conducted on either side of integrated Computer Ethics content within the rest of the curriculum.

This thesis examines the opinions of a sample of accounting students and a sample of accounting lecturers regarding the effect of prior study of accounting on performance in the first year university financial accounting course. A comparison is also made of actual performance in the first year course of two groups of students, those who have studied accounting at secondary school and those who have not. For the comparison of actual performance data were collected over a three year period (1985-1987). Two separate research designs were used to test for differences in performance. Both research designs indicated that students with secondary school accounting scored higher on early tests and examinations but that the two groups of students scored equally on the final examination. The survey of students' opinions included students from two universities. The major findings showed that students, regardless of whether or not they had studied accounting at secondary level, believed those who had to be advantaged in the first year financial accounting course. The majority of respondents indicated that high school accounting was, in their opinion, a desirable preparation for the university course. The survey of lecturers' opinions included lecturers from 15 South African universities. The findings of primary concern showed that lecturers believed students with prior exposure to accounting to be at an advantage in the first year financial accounting course.
