South African Higher Education has gone through various changes and challenges, one of these being the merger process. Various Universities and Technikons were forced to merge in an effort to aid the transformation and restructuring of the Higher Education landscape in the post-apartheid era. From an ICT point of view, the merged Institutions ended up with massive and distributed computing facilities. These facilities must be managed and secured and it can be appreciated that the complexity and magnitude of this task is compounded by the large and varied user population (i.e. students) using the facilities. With the exploding use of mobile consumer devices (such as cell phones, personal digital assistants, MP3 players, portable storage devices such as flash drives, etc), Higher Education Institutions are faced with the even more complex task of managing and securing the computing infrastructure, while large numbers of students can enter computer labs and use these devices at random. In some circles, portable devices are touted to be the next panacea in higher education. This, together with the popularity these devices enjoy under the student body, makes it a fait accompli that mobile consumer devices are “here to stay”. Therefore, banning these devices from campus computer labs, is not viable. Universities have to find ways to address security issues through the implementation of appropriate protective measures. This research focuses on finding a solution to mitigating the risks imposed on Higher Education Institutions in South Africa caused by the use of portable storage devices. The research proposes a framework which serves as an outline for the countermeasures that Universities must implement to mitigate the risks inherent to the use of portable storage devices. The scope of the research is limited to flash drives, smart phones and MP3 players.

Very little research is currently available about therapy conducted in chat-based Internet environments. Most of the existing research concerns therapy delivered via email or on-line support groups. For this reason, this review first presents an overview of literature concerning practical issues relevant to Internet-based therapy in general and then presents a review of the research that is available regarding therapy provided in chat-based Internet environments. The literature reviewed in this paper has been obtained from several on-line databases and Internet search engines. The available research on chat-based therapy has produced mainly anecdotal or inconclusive results. There is a need for controlled research that more clearly displays the relationship between an intervention provided in a chat environment and the participants' problems.

This thesis is a reception analysis using qualitative interviews to investigate the formation of cultural groups around computer-game LANs present in Rhodes University. It also looks at how issues of social inequalities evident on the university's campus impact on the participation of students in these LANs. The findings of this study are that the participants have established a community around the practice of computer LAN-gameplay based on values developed through the combination of the material and gameworlds. It serves as a home-on-campus for them; where they can fully explore their passion for games thus reaffirming their identity as gamers on a campus where being a gamer is viewed negatively. In this light, computer-game playing is not just a practice these participants perform, but a culture they live out every day. This is a culture predominantly lived out by men. One of the reasons for this is because most women have been raised to believe to have negative predispositions about digital gaming e.g. that it is childish, addictive and anti-social, but also that computer are meant to be used by men - women use them only when it is absolutely necessary, for example, that it is childish, for academic-related purposes. As a result, not many of them will use computers for any otherreason for fear of being socially criticised. In addition, the gaming culture being dominated by whites is due to the fact that admittance in to this community is still unaffordable for the majority of black students on the Rhodes University campus as a result of their social backgrounds.

The thesis of this study is that two seemingly disparate research disciplines can be coalesced to develop an effective pedagogical framework for educational design in the context of networked learning. That contention is grounded in, and inspired by, the rapid developments in educational technologies which have greatly changed the landscape in teaching and learning in higher education over the last decade. The study attempts to add to the corpus of contemporary learning theory which sees students not merely as passive recipients of knowledge, but as active participants in the learning process, having much greater control over their selection of technological learning tools, learning resources and learning methodologies. This is very much in line with the shift from the traditional focus on content design and knowledge transmission towards a more student-centred design for knowledge co-construction, a development which demands the type of new thinking about the design of learning tasks and learning resources contained in this study. Also set out are new lines of action for the fashioning of a collaborative learning environment, for community interaction and the sharing of knowledge, and for promoting good teaching and learning practice. The central argument of the study is that such pedagogical goals may be attained by juxtaposing the theories of Systemic Functional Linguistics (hereafter SFL) and pattern languages. These have not, thus far, been used in combination. SFL is a well established theory in the study of language, and is used in this thesis to help analyse and classify discourses produced and shared by teachers and students in networked learning. Pattern languages have their origin in architecture. Design patterns can be used as a means of representing and sharing important and specific empirical research results and design experiences. This new knowledge can be used to support and improve the quality of educational design. The study has two central components. The first uses the SFL theoretical framework to demonstrate how text is used as a key medium in networked learning. In other words, it is argued in this section that the quality of texts has a direct impact on the quality of learning and learning outcomes. The quality of text is assessed by means of a detailed discourse analysis of selected texts. This process involves deconstructing, identifying and capturing the linguistic resources and language strategies used in the texts. The detailed discourse analysis also illustrates and reveals how language is used in the construction of knowledge and the promotion of collaboration in teaching and learning. The second component centres on the argument that SFL provides valuable language knowledge which can be represented by using Alexander’s design patterns. New knowledge encoded in these design patterns can be used by teachers and designers as reusable and shared resources to help them improve their design work. The empirical research was carried out in three phases. The first involved a) the identification of text patterns of discourses used in networked learning based on detailed discourse analysis; b) Interviewing experienced academic staff to identify their perspectives on good online teaching practices and success factors. The second phase involved using the data which emerged from these interviews and discourse analysis to model illustrative patterns. (Here, illustrative means that due to the scope of the study, it is only possible to develop a limited number of patterns to illustrate the methods used for pattern development. It is not the intention to develop a full repository of design patterns in this study). In the third (validation) phase the patterns were reviewed by two groups of academic staff, with the aim of improving these patterns. Improved patterns were then tested on a group of educational design students for their usefulness and application. It is concluded from this research that it is possible to develop design patterns which ensure the best use of linguistic resources in both the teaching and learning process. Finally, it is argued that the combination of SFL and pattern languages provides a promising theoretical framework for the complex and demanding task of educational design. Future research could make use of such a framework to explore a fuller application of the pattern- based approach for the representation of new knowledge for educational design. Suggested additional research directions include finding new ways of capturing a new pedagogical approach to mobile learning and blended learning. Also, a promising direction could be the use of SFL Appraisal theory (Martin, 2000) for the investigation on how students construct interpersonal relationships (appraise peer work) in online joint projects. In the conclusion, it is contended that through its exploration of new ground in the use of SFL and pattern language theory in the construction of education design patterns, the study makes a significant contribution to knowledge in the field of networked learning.

The project presents a web-based component for a tutor training program at College of the Desert, Palm Desert, California. The application is designed to be responsive and adaptable to the tutor's needs. It also addresses the logistic and pedagogical problems that plague many community college tutor trainers and helps to mitigate this through an online instructional system that facilitates communication among the tutors so that learning can occur in a situated context.

Thesis (MComm)--Stellenbosch University, 2003.<br>ENGLISH ABSTRACT: As the information age evolves, society is undergoing changes based on developments in technology that have tremendous implications for the educational systems. Institutions of tertiary education are increasingly facing the pressures of globalisation. Associated with this is the knowledge society that demands experience with technology, different skills and a different learning experience (US, 2001). Furthermore, new information and communication technologies have demonstrated the potential to transform the way that knowledge is packaged, delivered, accessed and acquired, thereby altering higher educations' core production and delivery processes. Institutions of tertiary education that want to remain competitive, both locally and internationally, should, therefore, act proactively to facilitate the successful and innovative integration of relevant technologies into currently established practice and procedures. The University of Stellenbosch (US) recognises the importance of staying abreast with these global and local changes. The Virtual Information Space (VIS) project for optimal information sharing is a research initiative that developed as a direct response to the need for an inquiry into the functionality of alternative synchronous and asynchronous computer-mediated communication media (CMC), to be provided as part of the technological infrastructure of the US for enhanced information sharing and communication. The VIS project provides the framework within which this study was conducted. The aim of this study was to conduct an exploratory study through the use of empirical research and prototyping, by quantification of the usability of synchronous CMC media, for application in the South-African on and off-campus tertiary education environment (focused at post graduate level), in order to enhance information sharing between inter alia, information service suppliers, lecturers, students and researchers at the US. It was anticipated, however, that the degree to which the synchronous CMC media add value to the learning and information sharing processes within the VIS, will be influenced by the usability of the software applications within which the media are embedded, the perceived need of the role-players for the media, as well as the feasibility and viability of the systems when employed within the technological infrastructure of the US. These elements were, therefore, empirically investigated by conducting several usability experiments in a setting which simulated a usability laboratory, in order to acquire the necessary subjective and objective data, related to the identified goals and objectives that encapsulate the aim of this study. In order to demonstrate the value of the VIS environment, a theoretical perspective is provided by means of a literature review of the fundamental concepts of communities of practice and flexible learning. It is proposed that the use of the synchronous CMC media (embedded within the software applications) will assist in the creation of a VIS that supports the more advanced educational paradigm of constructivism by linking users into collaborative conversational networks, thus forming learning communities (better known as communities of practice) in cyberspace. The purpose of these communities is to create a means through which ideas and materials can be shared and exchanged, aiding individuals in building their own conceptual networks of interrelated ideas, strategies and theories and therefore construct and share knowledge. Information was obtained concerning participants' characteristics, preferences, needs and evaluation of the usability of the two software applications, NetMeeting and Yahoo Messenger, when utilised within the technological infrastructure of the US for the purpose of increased information sharing and communication. Performance measurement data (related to selected usability criteria) was obtained during the experimental phase, as well as information about the feasibility and viability of the systems when utilised within the technological parameters of the US. The analysis of the information consisted of descriptive statistics as the research aimed to illustrate the attitudes concerning usability, the perceived needs for the software applications, as well as the feasibility and viability of the systems. The results revealed that both NetMeeting and Yahoo Messenger were perceived by the participants as usable, achieving a positive rating on almost all of the dimensions of usability it was tested on. In the case on NetMeeting, technological limitations imposed on the system (such as bandwidth and network traffic) severely limited the effectiveness of the system as a whole and require further investigation to ensure successful implementation. Technological limitations in the case of Yahoo Messenger mainly centered on the unstable server environment that the system functions within. Hence, further research is therefore needed to ensure successful implementation and utilisation of NetMeeting and Yahoo Messenger within the technological parameters faced by the US.<br>AFRIKAANSE OPSOMMING: Soos wat die informasie-era ontplooi, is die samelewing besig om ingrypend te verander. Die dramatiese impak van die tegnologiese revolusie op die hoër onderwyssektor dwarsoor die wêreld hou dus aansienlike implikasies in vir tersiêre onderwysinstellings. Hierdie instellings is toenemend onderhewig aan die druk van globalisering en die kennis-samelewing wat al hoe meer vereistes stel in terme van ondervinding met tegnologie, verskillende vaardighede wat vereis word en 'n veranderende leer ervaring. Nuwe informasie- en kommunikasietegnologieë beskik oor die potensiaal om die maniere waarop informasie herwin, verwerk en gestoor word, te transformeer. Dit impliseer noodwendig 'n wysiging in die kern informasie produksie en -aflewerings prosesse van tersiêre onderwysinstellings. Sulke instellings word dus genoop om daadwerklik en pro-aktief op te tree ten opsigte van die suksesvolle en innoverende integrasie van relevante tegnologieë by bestaande prosedures, ten einde internasionale en nasionale mededingendheid te verseker. Die Universiteit van Stellenbosch (US) erken the belangrikheid daarvan om op hoogte te bly met verandering. Die Virtuele Informasie Spasie (VIS) projek vir optimale informasiedeling is 'n navorsingsinisiatief wat ontwikkel het vanuit 'n behoefte vir 'n ondersoek na die funksionaliteit van die verskillende sinkrone en asinkrone rekenaargebasseerde kommunikasie media, wat as deel van die tegnologiese infrastruktuur van die US voorsien sal word - ten einde verbeterde informasiedeling en kommunikasie teweeg te bring. Die VIS projek het 'n raamwerk verskaf waarbinne hierdie studie uitgevoer is. Die doel van hierdie navorsing was om 'n verkennende studie uit te voer, deur die gebruik van empiriese navorsing en prototipering, vir die kwantifisering van die bruikbaarheid van sinkrone rekenaar-gebasseerde kommunikasie media. Die spesifieke toepassingsarea is die Suid-Afrikaanse tersiêre onderwysomgewing (spesifiek gefokus op nagraadse vlak) met die doelom informasiedeling tussen informasiediensverskaffers, dosente, studente en navorsers te verbeter. Daar word egter verwag dat die graad waartoe die sinkrone media waarde toevoeg tot leer- en informasiedelings prosesse binne die VIS, beïnvloed sal word deur die bruikbaarheid van die sagteware waarbinne die media gesetel is, die waargenome behoeftes van die rolspelers vir die media, sowel as die uitvoerbaarheid en lewensvatbaarheid van die sisteme wanneer dit aangewend word binne die huidige tegnologiese infrastruktuur van die US. Hierdie elemente was dus empiries ondersoek deur die uitvoering van verskeie bruikbaarheidseksperimente in 'n omgewing wat 'n tradisionele bruikbaarheids laboratorium simuleer, ten einde the nodige subjektiewe en objektiewe data te ontgin wat gemik is op die doelwitte en mikpunte wat die strewe van hierdie studie omsluit. 'n Teoretiese perspektief word voorsien deur 'n literatuur-oorsig, ten einde die waarde van die VIS omgewing te konseptualiseer. Konsepte wat veral aandag geniet hou verband met die ontwikkeling van elektoniese gemeenskappe en buigsame leer omgewings. Die aanname word gemaak dat die gebruik van sinkrone rekenaargebasseerde kommunikasie media (soos gesetel in die sagteware pakkette, NetMeeting en Yahoo Messenger) die ontwikkeling van 'n effektiewe VIS sal fasiliteer wat 'n nuwe onderrigparadigma ondersteun. Die uitgangspunt van hierdie paradigma is dat kennis nie net weergegee moet word nie, maar dat dit gekonstrueer kan word soos wat die partye betrokke raak in relevante gespreksnetwerke binne die virtuele informasie spasie. So word elektroniese gemeenskappe dus geskep waarbinne individue idees en materiaal met mekaar kan deel en uitruil, terwyl kennis effektief geskep en gedeel word. Informasie is ingewin aangaande die deelnemers se kenmerke, voorkeure, afkeure, behoeftes en persepsies oor die bruikbaarheid van die sagtware pakkette, NetMeeting en Yahoo Messenger, wanneer dit aangewend word binne die tegnologiese infrastruktuur van die US, ten einde verhoogde informasiedeling en kommunikasie te bewerkstellig. Prestasiemetingsdata (gekoppel aan sekere bruikbaarheidskriteria) was ook verkry tydens die eksperimentele fase, sowel as informasie oor die uitvoerbaarheid en lewensvatbaarheid van die onderskeie sisteme wanneer dit aangewend word binne die huidige tegnologiese parameters van die US. Die analise van die data het beskrywende statistieke behels aangesien die navorsing ten doel gehad het om die ingesteldhede betreffende die bruikbaarheid en behoefte aan die sagteware pakkette, sowel as sekere tegniese aspekte rakende die stelsels, uit te lig. Die resultate het getoon dat die respondente beide NetMeeting en Yahoo Messenger as bruikbaar waargeneem het, aangesien 'n positiewe beoordeling op bykans al die dimensies van bruikbaarheid bereik was. In die geval van NetMeeting het sekere tegnologiese beperkinge van die sisteem, soos beperkte bandwyte, egter die effektiwiteit van die sisteem beduidend beinvloed. Tegnologiese beperkinge in die geval van Yahoo Messenger was hoofsaaklik as gevolg van die onstabiele omgewing waarbinne die bediener funksioneer. Verdere navorsing is dus nodig om suksesvolle implementering en aanwending van NetMeeting en Yahoo Messenger te laat realiseer, gegewe die tegnologiese parameters van die US.
