This evaluation started with preliminary research into the situations and problems in science classrooms and computer laboratories. The preliminary research identified teacher-centred lessons, learner and teacher conceptualisations, large numbers of learners per classroom, assessment, and a lack of interest in biology as some of the major problems in South African classrooms. The current research (because it is continuing) uses two Educational Computer Programmes (ECPs); a Computer-Aided Assessment (CAA) programme which is designed to alleviate problems in assessment, and Zadarh (a constructivist adventure game) designed to solve problems in biology classrooms, to further investigate some of the identified problems and find out the learners' and teachers' views on the utility of these two ECPs. The use of these two ECPs had not previously been investigated appropriately, especially in disadvantaged communities where teachers had little knowledge of the use and of evaluating ECPs. Therefore, a major concern for this study is that previous ECP evaluations excluded teachers and were not comprehensive enough especially for deploying ECPs in disadvantaged communities. A review of the methods that had hitherto been used, indicated that quantitative, mostly, behavioural and cognitive, pre-test post-test methods were prominently used, despite the shift in instructional design to constructional design, which embrace qualitative aspects of learning. Also, instructional design has evolved from behavioural models to include constructivist microworlds, which were unfairly evaluated by excluding qualitative benefits. Thus, this study seeks a more comprehensive evaluation strategy, in which teachers play the role of co-evaluators and which captures the qualitative and quantitative changes that software programs impart upon teachers' classroom practices, with sensitivity to the multiple disciplines in a program, as well as to the value systems of teachers. Comprehensive evaluation processes were facilitated during which 26 teachers in 23 schools in the Eastern Cape, KwaZulu Natal and Mpumalanga Provinces embarked upon the evaluation of the two ECPs. Evaluations were based upon a developmental, constructivist and interpretative approaches, by which teachers took ownership of these evaluations. Comprehensive evaluations revealed benefits from CAA and Zadarh, as well as benefits from direct teacher participations in the evaluations. CAA (Question Mark in this case) instantly provided diagnostic data. However, it was evident that the quality of diagnosis and remediation depended upon the quality of the test items, and the learning as well as the teaching strategies. Factors that could militate against the use and full utilisation of CAA in the schools where the study was done included the cost of software for CAA, teachers' capacity to set diagnostic test items particularly in a multiple-choice format, teachers' ability to interpret data produced by CAA, and teachers' skills in remedying their classroom problems as well as learners' problems. This study found that by playing Zadarh learners were able to construct knowledge through discovery and were attracted to the enjoyable aspects of this educational tool. Learners remembered most of those moments in the game during which they were both stuck and trying to solve problems on their way through Zadarh. Therefore, Zadarh can provide useful learning experiences with fun, and can improve motivation towards learning. Debilitating factors against the use of Zadarh and CAA include school curricula, which do not accommodate innovations, inflexible timetables, and classroom approaches that are teacher-centred. It was clear that the success of using computers in education would depend upon the ability of teachers to evaluate the ECPs, and to integrate ECPs into school curricula. drive these interactions played an important role in the successful integration of ECPs into classroom. One way of achieving such success is to include teachers as evaluators and co-designers of ECPs. Evaluations of ECPs therefore should: i) allow the teachers and learners, through social dialog, to identify how software could solve problems; ii) establish the compatibility of the software with the school curriculum; iii) ascertain the capacity of school computers to execute the software; and iv) provide support to the teachers in the use the software. Evaluations should benefit teachers and learners. The study concluded that a post-modern, developmental, and constructivist evaluation process might be one of the ways of enhancing training teachers in the use of the ECPs, in the concepts that the software deal with, and in evaluation. In that way, a socially contracted evaluation is comprehensive and can serve as a change agent through which teachers reflect and act upon improving their classroom practices. / Thesis (Ph.D.)-University of KwaZulu-Natal, Durban, 2004.

M.Ed. / Information and communication technologies are effecting widespread changes in all spheres of life including the educational context of South African higher education. While a great deal of emphasis is placed on the issue of bandwidth, and rightly so, the broader context in which the mediation of learning with computers takes place is still to a large degree neglected. It is within this context that the learning experiences of first time e-learners who had participated in the online semester course Education 2A at the R.A.U. University were examined. These students initially appeared to experience great difficulty adapting to the mode of participation in e-learning activity, suggesting that there was a mismatch between the values and priorities of learning as mediated by the web medium and the epistemology of learners situated in cultural practice. The initial problem of struggling to adapt to e-learning, was contextualised as a reciprocal process of interactivity in which the e-learner establishes a relationship with the cultural practice as the result of epistemological, methodological and ontological change. Sociocultural and activity theory provided the main theoretical foundation of this inquiry. In this theory there is a distinction between operations, actions and the overall activity that governs these and that situate the actions. The inquiry was therefore motivated by the need to understand and give substance to the learning experiences of first time e-learners within a systemic view of human computer interaction, as opposed to a cognitive approach to systems design (Kapetelinin in Nardi, 1996:46). Consequently, the inquiry examined the dynamic, reciprocal relationship of interactivity as mediated by the web medium, and epistemological, methodological and ontological transformation of the elearner, as she interacts in this ecosocial system. Motivated by the nature of the research problem and the socioconstructivist theoretical framework which framed my thinking around this problem, the inquiry was designed as a component of a larger action inquiry (Henning, Fortuin, Grobler & Brown, in progress), based on the principle of "communicative rationality" as proposed by Habermas (Ewert, 199 I :34) and conducted as qualitative and interpretive research. It was aimed not so much at monitoring and evaluating the course, but more at capturing and assessing the nature of student learning, specifically the processes of student communication and reflection in their lived experience in the course.

The starting point of this research is the observation that tutors in the Computing Sciences (CS) Department at NMMU require more support than they currently receive in order to be effective. This research project investigated how technology could be used to support tutors during practical sessions. Focus group discussions with tutors in the CS Department revealed that challenges exist which hinder them from effectively assisting students during practical sessions. Through analysis of focus group discussions and literature regarding the use of technology in education, it was determined that a tablet PC could be used to support tutors by providing on-demand access to practical content and answers to frequently asked questions. Existing models using technology in education to support either students or tutors in learning were investigated. A conceptual model using technology to support tutors during practical sessions was designed and proposed based on features of the existing models which were considered relevant to the CS context, and ways in which they could support tutors. Relevant features of the conceptual model include the system, purpose, boundary, key variables and best practices applied to the technological component of the model. During development of the model, these features were considered. In the context of the CS Department, a tablet PC tool was used by tutors as a means to support themselves and assist students during practical sessions. The tool is a component of the model which provides practical information. Each layer of the model’s three layer architecture was tested to ensure that the correct information is provided, on demand, to tutors during practical sessions. Positive results from a field study evaluation revealed that the conceptual model, using a tablet PC tool, could be applied to the CS context with the intention of supporting tutors during practical sessions.

A dissertation submitted in fulfillment of the requirements for the degree of Master in Technology: Information Technology, Durban University of Technology, 2011. / This study examines the perceived effect of the following factors on web searching ability of academic staff in the computing discipline: demographic attributes such as gender, age group, position held by the academic staff, highest qualification, etc; lecturing experience, research experience, English language proficiency, and web searching experience. The research objectives are achieved using a Likert-scale based questionnaire for 61 academic staff from Information Technology and Computer Science departments from four Universities from the Kwazulu-Natal and Eastern Cape provinces of South Africa. Descriptive and inferential statistics were computed for data analysis from the questionnaire after performing data reliability and validity tests using factor analysis and Cronbach‟s coefficients methods on the PASW Statistics 18.0 (SPSS). Descriptive statistics revealed a majority of staff from IT as compared to staff in CS and, a majority of under qualified middle age male staff in junior positions with considerable years of lecturing experience but with little research experience. Inferential statistics show an association between web searching ability and demographic attributes such as academic qualifications, positions, and years of research experience, and also reveal a relationship between web searching ability and lecturing experience, and between web searching ability and English language ability. However, the association between position, English language ability, and searching ability was found to be the strongest of all. The novelty finding by this study is the effect of lecturing experience on web searching ability which has not been claimed by existing research reviewed. Ideas for future research include mentoring of academic staff by more experienced staff, training of novice web searchers, designing and using semantic search systems both in English and in local languages, publishing more web content in local languages, and triangulating various research strategies for the analysis of the usability of web search engines.

Thesis (MPhil)--University of Stellenbosch, 2001. / ENGLISH ABSTRACT: The publication of the Report of the National Commission on Higher Education (NCHE) in 1996, the White Paper on Higher Education (1997) and the Size and Shape Report (2000) has profoundly changed the landscape of Higher Education in South Africa. Institutions of Higher Education have to re-think, among others, their teaching and learning strategies including the integration and use of technology. Although the use of technology in higher education is still in the early stages, the use of Information and Communication Technologies (ICTs) is growing rapidly. The University of Stellenbosch started to integrate the Internet in their teaching in 1998. Research was undertaken to find a suitable on-line course management system and Web Course Tools (WebCT) was chosen for this purpose. Since it was implemented, the use of WebCT has grown exponentially, although in most cases only as an add-on to classroom lectures. The World Health Organisation (WHO) Mental Health Disorders in Primary Care programme was the first programme developed as a full distance education course, delivered completely by means of WebCT and making use of the team approach to programme development. This programme was therefore chosen as the case study for this research. The purpose of this study is to apply 24 internationally developed benchmarks for quality on-line distance education to the WebCT component of the WHO programme in order to determine the applicability of these benchmarks for World Wide Web (WWW) programmes at the University of Stellenbosch. The research strategy for this study is a qualitative case study. Qualitative data was obtained by conducting semi-structured interviews with the individuals involved in the design, development and implementation of the WHO course. The study concludes that the 24 benchmarks cannot be applied to the current University of Stellenbosch context. The systems at the US will either have to be adapted, or established to meet the requirements of the international benchmarks. Another option for the US could be to develop their own benchmarks, taking international guidelines into account. / AFRIKAANSE OPSOMMING: Die publikasie van die Nasionale Kommissie vir Hoër Onderwys se verslag in 1996, die Witskrif vir Hoër Onderwys 1997 en die onlangse "Size and Shape" Verslag, het die scenario vir Hoër Onderwys in Suid-Afrika onherroeplik verander. Hoër Onderwys instellings is besig om, onder andere, die strategieë wat leer en onderrig bevorder, in heroorweging te neem en dit sluit die integrasie of gebruik van tegnologie as een van die belangrikste punte in. Alhoewel die gebruik van tegnologie in Suid-Afrika nog in 'n beginstadium is, groei die gebruik hiervan ongekend. Die Universiteit van Stellenbosch het sedert 1998 begin om die Internet in leer en onderrig te benut. Navorsing is gedoen oor 'n geskikte elektroniese kursusbestuurstelsel en die keuse het op "Web Course Tools (WebCT)" geval. Sedert die implementering hiervan het die gebruik eksponensiële groei beleef. In die meeste gevalle word WebCT bykomend tot klaskameronderrig gebruik. Die "World Health Organisation (WHO) Mental Health Disorders in Primary Care" programme was een van die eerste, volledige afstandsonderwysprogramme wat van die spanbenadering tot programontwikkeling gebruik gemaak het. Die program is daarom ook as gevallestudie vir hierdie navorsing gekies. Die doel van hierdie navorsing is om 24 internasionale kriteria vir kwaliteit Internet afstandsonderrig, toe te pas op die WebCT komponent van die bogenoemde WHO kursus, ten einde te bepaal of die kriteria toepaslik is vir Internetkursusse binne die Universiteit van Stellenbosch konteks. Die navorsingstrategie wat aangewend is om die doel van hierdie navorsing te bereik, is 'n kwalitatiewe gevallestudie. Kwalitatiewe data is verkry deur semi-gestruktureerde onderhoude met die persone te voer wat betrokke was by die ontwerp, ontwikkeling en implementering van die WHO program. Die afleidings wat deur hierdie studie gemaak word, is dat die 24 kriteria nie toepaslik is vir die huidige Universiteit van Stellenbosch konteks nie. Die US sal dus die huidige sisteme moet verander of sisteme vestig ten einde aan internasionale standaarde te voldoen. 'n Ander opsie sou wees om 'n eie stel kriteria, gebaseer op die internasionale kriteria, te ontwikkel.

The purpose of this project was to develop a WebQuesst investigation that would facilitate student Internet usage. A WebQuest investigation is an inquiry-oriented activity in which most or all of the information that learners interact with comes from resources on the Internet.
