One of the key features of curriculum change in South Africa in the last twenty years has been a move away from teacher centred instructional techniques to those that promote active participation of learners in their learning. Although the post democratic National Curriculum Statement has put emphasis on the importance of cooperative learning as a learner centred instructional technique, there is hardly any research on how teachers in schools understand and use it. This study sought to fill this gap by using a case study of seven mathematics classes in six schools. Data was collected through interviews, observations and document analysis.

This thesis investigates the process of peer collaborative learning in three Supplemental Instruction (SI) groups at Rhodes University. The roles of the SI leader, the students and the task in the peer-collaborative learning-teaching process were researched. The research is rooted in sociocultural theories of learning and development. The notion of activity is thus central to this investigation. The tasks, goals and interactions in the SI sessions were analysed in order to arrive at an understanding of the process of learning-teaching in each of the three SI sessions. A method of analysis devised by Van Vlaenderen to study the process of everyday cognition in the problem solving activities of community activists (1997) was adapted for this study. The method of analysis was used to study the interaction processes of participants in the SI groups. Each interaction between the SI participants was broken into its constituent parts and labeled in terms of the goals of the interactions in relation to the preceding interaction or operation, the task or subtask under discussion, and the SI session as a whole. Data from the analysis of the activity were quantified in order to assess the quality of the learning-teaching process. A qualitative analysis of the patterns of mediation was used in conjunction with the quantified data of interaction patterns to draw conclusions about the nature of the peer collaborative learning-teaching process in the three SI sessions. The research findings indicate that the nature of the SI task is crucial; students in SI need to be able and willing to participate; and the facilitation style of the SI leader plays a role in determining the quality of the activity in the SI session. The thesis explicates learning-teaching activity that results in higher order learning.

In the last years, the use of machine learning methods has increased remarkably and therefore the research in this field is becoming more and more important. Despite this fact, a high uncertainity when using machine learning models is still present. We have a wide variety of machine learning approaches such as decision trees or support vector machines and many applications where machine learning has been proved useful like medical diagnosis or computer vision, but all this possibilities make finding the best machine learning approach for a given application a time consuming and not welldefined process since there is not a rule that tells us what method to use for a given type of data.We attempt to build a system that, using machine learning, is capable to learn the best machine learning approach for a given application. For that, we are working on the hypothesis that similar types of data will have also the same machine learning approachas best learner. Classification algorithms will be the main focus of this research and different statistical measures will be used in order to find these similarities among the data.

Magister Educationis - MEd / This theses examined adult learners' experiences of group work in management education. Group work is an integral part of learning and teaching methods at most business schools because it develops team skills demanded by today's workplace. Furthermore, group work in education is grounded in the belief that much learning happens through social interaction and that diversity within groups promotes learning. This study analysed learners' group experiences in a business school. The study also aimed to identify conditions that hinder and promote group interaction with a view to enhance learning. / South Africa

The objective of this research study was to obtain a better understanding of the factors that affect lecturer and student participation in distributed collaborative learning assignments (DCLAs). A substantial number of courses worldwide have included DCLAs in their curricula in an attempt to teach students virtual communication and teaming skills, and to allow distributed students to learn course content collaboratively in a virtual environment. The execution and management of these assignments have proven to be more challenging that expected. Several attempts reported on in the literature had to be abandoned when cost exceeded the rewards for both lecturers and students. In a fouryear cyclical action research project carried out at the PETech (Port Elizabeth Technikon, currently part of the Nelson Mandela Metropolitan University, South Africa), ICT students at several of the PETech campuses were required to complete a DCLA in virtual teams. This project also had to be terminated when it was realised that virtual team learning was minimal and the time investment unacceptably high. For the research study reported on in this thesis the data collected during the four “preresearch” cycles and the experiences reported in the literature were analysed. The lessons learnt were applied to a new additional DCLA cycle which formed part of an ICT course, although this execution still showed room for improvement. A second additional cycle was then executed which had a high participation rate and was overwhelmingly labelled by the participating students as a valuable and enjoyable learning experience. Analysis of the factors affecting participation in DCLAs shows that they are numerous and tightly interlinked, and that each factor is able to take on a wide range of values. This complicates descriptive reporting as each of the DCLAs was unique with unique outcomes and would have to be reported as such in order to iii ABSTRACT iv gain an understanding of the factors. Hence, a level of abstraction was needed, which was accomplished by applying the traditional Glaserian grounded theory method to the data collected during the four “preresearch” and the two additional cycles, and from the literature on the topic. The outcome is a perceived costs and rewards (PCR) theory for participation in DCLAs. As participation is crucial for the learning experience of each student as well as his/her team members in an action learning environment, deciding on participation by continually calculating the costs versus rewards became the focal point of the theory. To the best of the author’s knowledge this research study makes a theoretical contribution to the existing body of ICT educational knowledge in the form of a perceived costs and rewards theory for DCLA participation and a practical contribution in that it provides a theory that can be used to explain, understand, interpret and predict participation in DCLAs. This research study provides guidance for future research in both of these areas.
