M.Ed. / Technical development, which has its roots in technical education is a high priority in any developing country that aims at the creation of well being for all its citizens. On the other hand, over the past decades, technical education in the Republic of South Africa has not been able to offer sufficient drive to become a contributing factor to bring about the expected economic growth. Certain underlying causes in this regard, were and are today still acceptable. Although certain practical experience in industry is a prerequisite for entry into the education profession, this experience is ignored in terms of salary, promotion service and leave once the person is a fully fledged member of the profession. This is surely the greatest contributory factor to the disillusionment of these teachers during the past decades. Should this underlying problem be removed, it will serve as the necessary stimulus for the people concerned to address the technological demands and a new dimension will occur. The role that the well qualified teacher plays in any teachingand learning situation cannot be over emphasized. He serves as an important bolster against didactic neglect of the child. Should the most recent discussion documents namely the CUMSA, National Training Board as well as the ANC's points of view in connection with educational affairs be integrated, the possibility of an excellent epucational policy may result. The following are the main points from the discussion documents that address the proposed training model: * technology education and engineering studies, which are regarded as career subjects in the senior secondary phase, may be taken as choice subjects. * the possible integration of education and training. * that the modular system to the curriculum with its exit points be followed at schools. * that an adult trainer will receive recognition by means of a certification council for all previous learning and teaching experience (formal as well as informal). The proposed training model in this study makes provision for the trainers, namely that the fechnical teachers who comply with the provisions/requirements of the proposed model be accountably and financially considered qualified so s to optimally fulfil their education and teaching tasks.

Interference of natural environment by invasive plants is a global concern. In South Africa and in particular Gauteng Province, interference of natural land by invasive plants that originated from other countries has been an endemic problem. These invasive plants pose a threat to biodiversity as a result of its wild and wide dispersion rate where it spreads into neighbouring Provinces such as Mpumalanga, Limpopo, North West and the Free State. Pompom weed is aggressive to control and can spread by means of both wind and water. This research project investigates problems associated with ineffective control of invasive plants in general and pompom weed in particular. State organs, Non Governmental Organisations (NGOs) and farming communities were identified as relevant respondents in this study. Three hundred (300) validated questionnaires were distributed to these stakeholders and 286 were adequately completed and received. These were analysed and the data interpreted. Results obtained showed that lack of coordination and teamwork from all stakeholders are responsible for ineffective control of invasive plants in the country. The use of biological control was recommended for the control and eradication of the invasive plants. / Environmental Sciences / M.A. (Environmental Management)

Work integrated learning (WIL) for the training of engineering technicians and technologists combines the theoretical learning of the fundamentals with their practical application in a real-world situation and environment. The activities in WIL are intended to provide students with specific learning outcomes in each engineering field of study, as well as with the general skills that are necessary for engineers in any field. The WIL learning outcomes are very specific and provide the student with the opportunity to practise and apply the fundamentals in an actual workplace. WIL includes various modalities such as problem-based learning, project-based learning and workplace learning. In this thesis, work integrated learning is referred to specifically as a period of work placement for engineering students. The other modalities of learning are usually included in all engineering qualifications. Thirty percent of the curriculum for the National Diploma engineering qualification in South Africa consists of work integrated learning, which translates into approximately 120 credits. WIL provides a valuable context for learning. However, there has been debate about the offering, placement, quality and supervision of it. This thesis investigates the various factors that may affect the offering of this component of learning in addition to ascertaining the importance of WIL in the training of technicians and technologists. This research comprises a survey conducted among engineering students as well as interviews with lecturers and supervisors directly involved in the implementation of the WIL component. The study investigates the format of WIL and its duration, the presence or absence of supervisors, mentors, a syllabus and clear guidance within the context of the Higher Education Qualification Frameworks. Quantitative data was collected from Engineering National Diploma and B-Tech students in two universities in Gauteng and then captured and processed. Statistical analysis such as factor analysis, analysis of variance, Cronbach’s Alpha coefficient, Pearson chi-squared, the Bartlet test and others were carried out, using various standard tests. The study reveals the extent to which both students and lecturers appreciate WIL. The study also offers recommendations for the unique and on-going collaboration between industry and academic institutions for the purpose of the training of future technicians. In addition, it provides reasons for the possibility of a shorter work placement period provided certain preparations are made by the universities prior to placement. It highlights the need for clarity on the responsibilities of the role players involved and on assessment methods, and for the provision of a more specific, yet flexible, curriculum, while also recommending regular reflection on this component of learning. All of these points are discussed within the context of the Higher Education Qualification Framework in South Africa. This framework recommends that higher education institutions accept responsibility for WIL placement and for ensuring that programmes are properly structured and supervised. / Science and Technology Education / D.

The current South African legislative framework does not properly address the unequal bargaining position between employers and fixed term employees. Ineffective regulation of fixed term employment in South Africa has had the effect of excluding certain groups of fixed term employees from claiming the remedies provided in terms of the Labour Relations Act and other labour legislation. Furthermore, where remedies are applicable to them they are often ineffectual. Interpretational variation evident from case law pertaining to the enforcement of the rights of fixed term employees, indicate clear lacunae in the unfair dismissal protection afforded to these vulnerable employees. This is mainly a consequence of uncertainties related to the interpretation of the legislative provisions. The infusion of the values entrenched in the Constitution of the Republic of South Africa and the development of the common law to reflect these values might augment the scope and availability of rights enjoyed by fixed term employees. But, changing socio-economic and political circumstances necessitates review and amendment of the legislation applicable to fixed term employees to meet the country’s constitutional and international obligations. Proposed amendments to the Labour Relations Act have been tabled. These amendments may be capable of addressing some of the current problems. However, they may also lead to other undesirable consequences. An investigation into problems related to the application of similar provisions as those proposed by the Labour Relations Amendment Bill in other jurisdictions crystallises some possible causes for concern. Some of the proposed changes could create new vulnerabilities, or renew old ones. / Private Law / LL. D.

The research undertaken involves a quasi-experimental approach in determining the impact of the Competency and Placement (CAP) test in the Further Education and Training (FET) colleges. The evaluation became necessary because poor learner performance within the National Certification Vocational (NCV) programme has persisted amid the implementation of a country-wide roll-out of the CAP test; and a recapitalisation injection of R1.9m. Learner performance data relating to the NCV programme and CAP was obtained in order to undertake an accurate analysis of the poor performance within the FET college sector. In addition to the above, qualitative data was obtained through semi-structured interviews with CAP participating colleges in the country. Recommendations included the restructuring of the NCV programme; the introduction of an alternative learner placement methodology that was in line with international best practices; and improving quality assurance aspects pertaining to the capacity at colleges to deliver the NCV programme effectively. / Human Resources Development / M.

The purpose of the study was to explore the relationship between mathematics teachers’ subject matter knowledge and their teaching effectiveness. A convenient sample of 19 grade 11 mathematics teachers and 418 students were initially selected for the study and took part in some stages of the study. Of this lot, only 11 teachers and 246 students participated in all the stages of the study. Explanatory Mixed methods research design which entails the use of a co-relational study and a descriptive survey design were employed in the study. Data was collected from the teachers using a self report questionnaire, Teacher Subject Matter Knowledge of Trigonometric Functions Scale (TSMKTFS) and peer evaluation questionnaire, and from students using teacher evaluation questionnaire and Student Trigonometric Functions Performance Scale (STFPS). All the instruments had their validity and reliability accordingly determined. Quantitative data gathered was analysed using descriptive and inferential statistics while qualitative data gathered from teachers’ and students’ tests were analysed using task performance analysis. It was found that a positive, statistically significant relationship existed between teachers’ subject matter knowledge and the composite measure of their teaching effectiveness. The relationships between teachers’ subject matter knowledge and students’ achievement and also between teachers’ subject matter knowledge and students’ rating of the teachers’ teaching effectiveness were found to be positive and statistically significant. However, the relationships between teachers’ subject matter knowledge and teachers’ self rating as well as teachers’ subject matter knowledge and peers’ rating of teachers’ teaching effectiveness were not found to be statistically significant though they were positive. Further data analysis showed that there was a difference between the subject matter knowledge of effective and ineffective teachers and also between the students taught by effective teachers and the students taught by the ineffective teachers. / Institute of Science and Technology Education / PhD (Mathematics Education)

Om effektiwiteit te beoordeel, word evaluering vereis en derhalwe behoort instruksionele evaluering 'n integrale komponent van die instruksionele ontwerpgebeure te vorm. Die SANW beskik nog nie oor toereikende kundigheid om hierdie komponent tot sy reg te laat kom nie en die doel van die studie was om hierdie leemte aan te vul. Daar is eerstens gepoog om, deur middel van 'n literatuurstudie, die didakties-wetenskaplike basis te bepaal waarop evaluering binne 'n sisteembenadering tot opleiding behoort te berus. Daarna is die aard en rol van instruksionele evaluering in die instruksionele ontwerpsisteem binne 'n militere opleidingsmilieu verken, ten einde te kon bepaal wat die funksies van instruksionele evaluering behels en welke evalueringstake in die verskillende fases van 'n instruksionele ontwerpprojek uitgevoer behoort te word. Die fokus van die studie het vervolgens verskuif na die talle veranderinge wat sedert die ontstaan van die SANW op 26 April 1994, na die eerste ten volle demokratiese verkiesing in die Republiek van Suid-Afrika, ingetree het.

Instructional design - an approach that has developed from instructional technology - is used to establish new courses that facilitate effective training. Evaluation is essential for assessing effectiveness and therefore instructional evaluation should form an integral part of the learning events. The SANDF does not as yet have the expertise to do justice to this component, and the aim of this study was to fill this gap. Firstly, it was attempted to determine, by means of a literature study, the didactic scientific foundation on which evaluation within a systems approach towards training should rest. The nature and role of instructional evaluation in the instructional design system within a military training milieu was subsequently investigated. This was done to determine what the functions of instructional evaluation comprise and what evaluation tasks should be carried out in the different phases of an instructional design project. The focus of the study then shifted to the numerous changes that took place since the inception of the SANDF on 26 April 1994, after the first democratic election in the Republic of South Africa. Compared to its predecessor the SANDF has new and more extensive secondary roles that demand higher standards of training and make evaluation a more complicated task This indeed confirms the need for an evaluation system that is practised according to system principles. Against the background of the afore-mentioned, the design of an overall instructional evaluation system for the SANDF was proceeded with. As the successful implementation and functioning of the system is, to a large extent, influenced by the way in which the instructional evaluator carries out this task, attention was finally given to the design of a course for instructional evaluators. / Curriculum and Instructional Studies / D.
