Full textAbstract:
Research was done on gamers’ perceptions of the service quality in the gaming areas of selected
casinos in South Africa. 2 casinos with 700 and more slot machines and 2 casinos with fewer than 700
slot machines were used in this research project to obtain a summary of the target population. 440
gamers at the 4 selected casinos were interviewed, with the help of trained fieldworkers. A structured
questionnaire was used to collect the final data for the research. All variables related to the
questionnaire were statistically analysed. The results of the research indicated that there were no
significant differences between the male and female gamers’ perceptions of the service quality in
gaming areas.

Full textAbstract:
Thesis (DPhil (Drama))--Stellenbosch University, 2009.The purpose of this study is to examine critically the phenomenon of participatory video and to situate within this the participatory video project that was initiated as part of this study in the informal settlement area of Kayamandi, South Africa. The overall objective of the dissertation is to consider the potential of participatory video within current-day South Africa towards enabling marginalised groups to represent themselves and achieve social change. As will be shown, the term ‘participatory video’ has been used broadly and applied to many different types of video products and processes. For the preliminary purposes of this dissertation, participatory video is defined as any video (or film) process dedicated to achieving change through which the subject(s) has been an integral part of the planning and/or production, as well as a primary end-user or target audience. The two key elements that distinguish participatory video are thus (1) understanding video (or film) as a tool for social change; and (2) understanding participation by the subject as integral to the video process. An historical analysis thus considers various filmmaking developments that fed into the emergence of participatory video. These include various film practices that used film as a tool for change -- from soviet agitprop through to the documentary movement of the 1930s, as well as various types of filmmaking in the 1960s that opened up questions of participation. The Fogo process, developed in the late 1960s, marked the start of participatory video and video advocacy and provided guiding principles for the Kayamandi project initiated as part of this dissertation. Practitioners of the Fogo process helped initiate participatory video practice in South Africa when they brought the process to South African anti-apartheid activists in the early 1970s. The Kayamandi Participatory Video Project draws on this background and context in its planned methodology and its implementation. Out of this, various theoretical issues arising from participatory video practice contextualise a reflection and an analysis of the Kayamandi project. Lastly, this study draws conclusions and recommendations on participatory video practice in South Africa.

Full textAbstract:
The SASL project at the University of the Western Cape aims at developing a fully automated translation system between English and South African Sign Language (SASL). Three important aspects of this system require SASL documentation and knowledge. These are: recognition of SASL from a video sequence, linguistic translation between SASL and English and the rendering of SASL. Unfortunately, SASL documentation is a scarce resource and no official or complete documentation exists. This research focuses on creating an online collaborative video annotation knowledge management system for SASL where various members of the community can upload SASL videos to and annotate them in any of the sign language notation systems, SignWriting, HamNoSys and/or Stokoe. As such, knowledge about SASL structure is pooled into a central and freely accessible knowledge base that can be used as required. The usability and performance of the system were evaluated. The usability of the system was graded by users on a rating scale from one to five for a specific set of tasks. The system was found to have an overall usability of 3.1, slightly better than average. The performance evaluation included load and stress tests which measured the system response time for a number of users for a specific set of tasks. It was found that the system is stable and can scale up to cater for an increasing user base by improving the underlying hardware.

Full textAbstract:
Cell phones have become a ubiquitous part of daily life for both teachers and learners alike. The educational potential afforded by cell phones is diverse. The challenge for teachers is to capitalise on this ubiquity and make use of cell phones for educational purposes. This study investigates how cell phones can be used in the teaching of Mathematics using VITALmaths video clips. Five VITALmaths video clips were uploaded onto cell phones which were used in the classroom to explore the Theorem of Pythagoras in a visually appealing way that supported a conceptual understanding of the basis of the theorem. The study was conducted in two high schools in Grahamstown, South Africa. It involved two teachers from each school and a total number of 47 Grade 10 Mathematics students. The participating teachers were chosen from a group of Mathematics teachers taking part in the Mathematics Teacher Enrichment Programme (MTEP) of the FirstRand Foundation Mathematics Education Chair hosted by Rhodes University. This study is framed as a case study and is grounded within the interpretive paradigm. The study captures teachers’ and learners’ experiences in using cell phones as instructional aids within the pedagogical context of the classroom. This research suggests that cell phones can be a useful resource to support teaching and learning in the classroom, particularly in under-resourced schools. The use of VITALmaths video clips as mathematical content, and cell phones as a vehicle of delivery, enhanced active participation and concentration, sped up lessons, encouraged collaboration as well as interaction and hands-on exploration, and promoted both student autonomy as well as teacher enrichment.

Full textAbstract:
Includes bibliographical references.Assessing invertebrate species diversity and distribution based on environmental predictors is essential for conservation planning. South Africa need to understand ecological patterns to better plan for species conservation. South Africa’s unique coastline requires additional protection, but the design of areas is reliant on evidence based research. South Africa has a distinctive marine environment and is host to tropical, subtropical and temperate invertebrate species. False Bay in the Western Cape province of South Africa is a biodiversity hotspot with high species richness due to the overlap of two bioregions. This project reports on the first comprehensive camera survey of False Bay’s invertebrate population and assesses diversity across more habitat types and a greater depth range than previous dredge studies. 154 sites were sampled across summer and winter, reef and sand and three depth categories: shallow (5-15 m), intermediate (16-30 m) and deep (31-50 m). A total of 67 species from 8 phyla were recorded in this study. Winter samples showed a greater diversity than those sampled in summer (p=0.004). Intermediate depths (Shannon-H=1.184) and reef substrate (Shannon-H=1.403) support a greater diversity of invertebrate species. Habitat emerged as the most significant predictor of species distribution in the bay (p=0.01). Depth (p=0.01) and season (p=0.03) were also of influence, but to a lesser extent. Reef sites were separated from sand sites by the presence of Jasus lalandii and Comanthus wahlbergi on the former and Bullia laevissima, Marthasterias glacialis and Ovalipes trimaculates on the latter. Reef species J. lalandii and Tropiometra carinata and sand species B. laevissima and M. glacialis had the greatest contribution to dissimilarity between winter and summer samples. Complex granite reefs should be a main priority in invertebrate conservation as they host the greatest species diversity and abundance of all habitats sampled. BRUVs have provided a non-invasive, non-destructive method of sampling invertebrate species on all habitat types and are recommended for use in future studies of invertebrate species composition.

Full textAbstract:
This qualitative study examines the use of Visual Technology for the Autonomous Learning of mathematics (VITALmaths) video clips in three Grade 9 classrooms in the Eastern Cape, South Africa, two of which are in well-resourced ex-Model C schools and one in a semi-rural township school. The rapid development of mobile technology, especially in Africa, has opened up previously unexplored avenues in economy, communication and education (Aker & Mbiti, 2010), with a number of mobile learning initiatives being launched in South Africa (Botha & Ford, 2007; Vosloo & Botha, 2009). The VITALmaths project was developed collaboratively between the University of Applied Sciences Northwestern Switzerland and Rhodes University in South Africa (Linneweber-Lammerskitten, Schäfer and Samson, 2010). As the main platform for dissemination of the video clips is the cell phone, the study looked at the various aspects involved in the use of cell phones by learners in the classroom, as well as the incorporation of the clips into the teaching of three teachers. Consideration was given to whether or not the clips assisted the teachers in teaching, as well as whether or not they encouraged further exploration. The study was divided into six stages during which data was collected and analysed using an interpretive approach throughout. Data collection methods included semistructured interviews, questionnaires, observation, journals and reflective essays. The study revealed the participating teachers, having incorporated the clips into several lessons, found that these had a meaningful effect on their teaching practice, as well as on the engagement of the learners in the lessons. The majority of the learners involved in the study had access to cell phones, either their own or borrowed, and were able to download the video clips onto their phones from the website (www.ru.ac.za/vitalmaths). A number of learners found that the clips helped them find examples of specific mathematical concepts outside of the classroom, thus leading to further enquiry and exploration, while several learners downloaded and viewed additional clips. Overall findings showed that the VITALmaths video clips could be incorporated into teaching with relative ease.

Full textAbstract:
Thesis (DTech (Electrical engineering))--Cape Peninsula University of Technology, Cape Town, 2007Telemedicine has been identified as a tool to distnllUte medical expertise to medically underserved rural community. However, due to the underdeveloped or non-existent telecommunication infrastructure, which is needed as the platform for telemedicine, the full benefits of telemedicine are yet to be realized in most parts of South Africa and Africa as a whole. This study aims to explore ways on how to provide lP-based lCI system that can be used as a communication platform for telemedicine in rural areas. In order to emulate the onsite face-to-face consultation experience, the rural telemedicine system must be able to provide quality video transmission. Quality video is also important in order for the physician at the distant end to be able to make correct diagnosis. Hence the main focus of this study is on ways ofproviding quality video over lP-based multiservice network. A conceptual model of a rural area network that can be used for rural telemedicine has been deVeloped, and different access technologies that can be used for rural areas are presented. Techniques for compesating IP best effort datagram delivery are provided. Factors that can affect the quality of video transmission on an lP-based packet network are identified, and a holistic approach to mitigate them is proposed. That includes adopting coding techniques that will provide coding efficiency, high quality video that is consistent at high and low bit rates, resilience to transmission errors, scalability, and network friendliness, which will result in perceived quality improvement, highcompression efficiency, and possibility of transportation over different networks. Secondly, it also includes mechanisms to compensate for packet networks idiosyncrasy, especially JP best-effort debilities, in order to meet the latency and jitter requirements of real-time video traffic. For video coding, H.264 is proposed as it meets most of the encoding requirements listed above, and for prioritising and protecting.video traffic from JP network's best-effort debilities a combination of differential services (DiflServ) and multi-protocol label switching (MPLS) have been adopted, where DiflServ is used for traffic classification and MPLS is used for traffic engineering and fast-rerouting in the event of route failure. To verify and validate the proposed solutions, modelling and simulation has been used, where the Network Simulator (NS-2.93) has been used to simulate network functions, and PSNR, VQM score and double stimulus impairment scale (DSIS) have been used for evaluating video quality.

This project explores and shares the stories of post-natural builders in South Africa who use re-purposed waste materials and natural materials to build “shack-replacement” houses and community structures. The project supported the builders with advocacy tools and generated a model for creative collaboration suited for supporting empowering community engagement in other contexts. The project’s video narratives and multi-media artworks share stories of how the post-natural building practice connects builders to cultural identities associated with traditional architecture, builds local capacities through training and community activity, and provides inexpensive, climate-appropriate shelter.

Full textAbstract:
Visual records of place remain to a large degree inadequate when attempting to make visible the ephemeral states of consciousness that underlie the damage wrought by brutal regimes, let alone make visible the extraordinary histories and power structures encoded in images and views. This practice-led dissertation examines an emerging critical landscape genre in post-apartheid South Africa and Namibia, and its relationship to specific themes such as identity, belonging, trauma and memory. The landscape genre was traditionally considered inadequate to use in expressions of resistance under apartheid, particularly in the socially conscious and reformist discourse of South African documentary photography. I argue that, as a result of historical and cultural shifts after the demise of apartheid in 1994, a shift in aesthetic and subject matter has occurred, one that has led to a more rigorous and interventionist engagement with the landscape genre. I demonstrate how, after 1994, photographers of the long-established documentary tradition, which was meant to record 'what is there' in a sharp, clear, legible and impartial manner, would continue to draw on devices of the documentary aesthetic, but in a more idiosyncratic way. I show how these post-apartheid, documentary landscapes both disrupt and complicate the conventional expectations involved in converting visual fields into knowledge. I further investigate, through my own experimental documentary work, the ideologically fraught aspects of landscape representation with their links to Calvinist and German Romantic aesthetics. I appropriate and disrupt certain tropes still prevalent in popular landscape depictions. I do this in an effort to reveal the complex and troubled relationship that these traditions share with issues of willed historical amnesia and recognition in contemporary Namibia. Through my practice and the examination of other photographers' and artists' work, this project aims to further a self-reflective and critical approach to the genre of landscape and issues of identity in post-apartheid South Africa and Namibia.

This research investigates the gendered nature of video arcades and video games, in
relation to the perceptions and attitudes of the users to them. Video arcades are
relatively recent sites of leisure and engagement with electronic games. Very little
research (if any) in this area has been done in South Africa.
This research is concerned with both media and gender and draws on a theoretical
framework informed by poststructural understandings of gender construction and
discourse.
The research also examines users' habits and attitudes to and perceptions of the video
arcades, the games and their narrative scenarios, in relation to gendered behaviours.
As a Media Educator, these findings reinforce the researcher's belief in an urgent

Thesis (M.M. (Entrepreneurship and New Venture Creation)), University of the Witwatersrand, Faculty of Commerce, Law and Management, Wits Business School, 2016.Over the past few years the South African market has seen the launch of a number of online video services providers. The leading providers in the industry are Vidi, ON-Tap, MTN front row and ShowMax. The industry has also attracted some international competition with big players like Netflix launching its services in the South African market in January 2016. Although this industry has seen the emergence of many new players, it is still in its infacy stages in South Africa and is still to be seen if it will mature into a long term profit making industry. It is important to research the diffusion of innovation and more specially to look at how technopreneurs that are in this field or considering entering this industry can influence the speed and success of how this new innovation is diffused. This research will focus on two areas. Firstly, it will seek to look at the factors that influence the potential adopter’s propensity to adopt a new product. Secondly the research will look at the role played by the technopreneur in ensuring that online video services are adopted successfully. Since the online video services industry is not yet mature the research was conducted using the mixed method approach. The quantitative research was conducted by distributing online survey questionnaires. These questionnaires were distributed using email, as well as social media networks such as Facebook, Twitter and Linkedin. The qualitative research was conducted by performing interviews with a predetermined list of respondents. The combination of the two types of research led to a better understanding of this topic. The results the research highlighted the fact that the South African market poses very unique challenges for entrepreneurs that want to enter this industry. South African technopreneurs have an advantage against international players like Netflix because they understand challenges of internet access, payment issues as well as preferred content.

The researcher attempts to establish the significance of video evidence analysis in the investigation of murder cases against the police. The evidence obtained could be crucial and admissible in court and ultimately resulted in the successful prosecution of an accused person. In order for investigators to conduct an effective investigation, it is important that they become familiar with the application of video evidence, its purpose, benefits and shortfalls.
In order to achieve the intended goals and objectives of video evidence, the investigators should know how to collect, package, process and analyse video evidence.
The clarification and processing of the crime scene of video evidence as well as the identification of a suspect at the scene of crime is very much important and without video evidence it would be difficult to convict an accused person in a court of law.Police Practice

The preferred method of communication amongst Deaf people is that of sign language. There are problems with the video quality when using the real-time video communication available on mobile phones. The alternative is to use text-based communication on mobile phones, however findings from other research studies show that Deaf people prefer using sign language to communicate with each other rather than text. This dissertation looks at implementing a gesture-based interface for an asynchronous video communication for Deaf people. The gesture interface was implemented on a store and forward video architecture since this preserves the video quality even when there is low bandwidth.
In this dissertation three gesture-based video communication prototypes were designed and implemented using a user centred design approach. These prototypes were implemented on both the computer and mobile devices. The first prototype was computer based and the evaluation of this prototype showed that the gesture based interface improved the usability of sign language video communication. The second prototype is set up on the mobile device and it was tested on several mobile devices but the device limitation made it impossible to support all the features needed in the video communication. The different problems experienced on the dissimilar devices made the task of implementing the prototypes on the mobile platform challenging. The prototype was revised several times before it was tested on a different mobile phone.
The final prototype used both the mobile phone and the computer. The computer served to simulate a mobile device with greater processing power. This approach simulated a more powerful future mobile device capable of running the gesture-based interface. The computer was used for video processing but to the user it was as if the whole system was running on the mobile phone. The evaluation process was conducted with ten Deaf users in order to determine the efficiency and usability of the prototype. The results showed that the majority of the users were satisfied with the quality of the video communication. The evaluation also revealed usability problems but the benefits of communicating in sign language outweighed the usability difficulties. Furthermore the users were more interested in the video communication on the mobile devices than on the computer as this was a much more familiar technology and offered the convenience of mobility.

of transformations in the television broadcasting sector in the early 1990s. South
African documentary film and video is located within a theoretical framework that
interweaves documentary film theory, theories of Third cinema and of identity, rid
working class cinema of the 1920s and 1930s.
The concepts of ‘voice’ and the ‘speaking subject’ are the two key concepts that focus
the discussion of strategies of representation in detailed textual analyses of selected
documentaries. The analysis of three documentaries that typify the output of Video
News Services reveals how these documentary texts establish a symbiosis between
representations of the working class as black, male, and allied to COSATU, and the
liberation struggle. The analysis of selected documentaries from the Ordinary People
series highlights those strategies of representation that facilitate perceptions of the
multiplicities of identities in South Africa. This focus on representations of identity is
extended in analysing and comparing two television series. The strategies of
representation evident in the Video News Services documentaries and the meanings
they produce about identify are repeated in the series called Ulibambe Lingashoni:
Hold Up the Sun. In Soweto: A History, strategies of representation that follow the
trend towards representing identity as multiple are used to present history as if from
the perspective of ‘ordinary’ people.
The thesis creates an argument for South African documentary film and video to
move towards strategies of representation that break down the fixed categories of
identity developed under apartheid. With policy moves for creating more ‘local
content’ films and television productions there is opportunity to re-shape the
documentary film and video movement in South Africa using representational
strategies that blur the boundaries between documentary and fiction, and between
individualised, discrete categories of identity.

This thesis explores the potential of video as a research
tool for anthropologists in the recording of a single
ritual. The study examines interactions between
ethnographers, informants and viewers. The thesis
reveals the capacity of video to make possible close,
detailed readings of performance in terms not originally
anticipated by the researcher. Archival storage of the
video recording allows for critique and assessment of the
research.
The case study chosen in which to test the potential of
\ dcso as a research tool was a woman's 'initiation'
r^L'ial (called inton jane) in Shixini in the Eastern Gape
(in what was, until recently, the independent homeland of
Transkei). Historically, the ritual was supposedly held
at the time of a girl's first menstruation, this being
the physical symbol of her transformation into adulthood.
Ritual seclusion served to effect an accompanying social
transformation in preparation for marriage.
Paradoxically, in the late 1980's, it was older women and
mothers, already married and well past the age of first
menstruation, who were undergoing the ritual seclusion
and symbolic marriage. The study explores this paradox
with the goal of understanding the purpose of the ritual
in contemporary times. By recording large segments of
the ritual on video, and subjecting the footage to a
close analysis of verbal and non-verbal aspects of
performance, both the ritual and the merits of video as
a research tool could be examined.
Video was utilised, in an interactive research process,
as an information elicitation tool. The analysis of the
recorded text of the ritual brings to the fore elements
which make what is apparently a paradox understandable.
The elements which explicate the paradox were not
anticipated when the research commenced, and in all
likelihood would have eluded a researcher who did not
have the benefit of the incidental capture on video. The
thesis reveals the enormous Contribution video can make
to research and suggests that video has an important
contribution to make to the discipline of anthropology.

This study examines the means by which Clive van den Berg (b.1956) presents and explores the South African landscape and recent past, and in so doing examines the evolution of van den Berg's process of looking and interpretation. Seminal to such an investigation is a Critical examination of what history, memory and landscape are or might be perceived to be. Chapter.One centres on an evaluation of these terms and comprises a discussion of their perceived meanings particularfy as they relate to the visual arts, and especially in terms of South African art history. The investigation is facilitated by an examination of key works produced by van den Berg between 1983, which marks the commencement of the Views from the Oasis Series, and 1998, the year in which van den Berg produced the sculptural piece that comprises his contribution to the !Xoe Site Specific Project. In addition, it was in 1998 that van den Berg added the medium of video to his range of materials. Selected examples of van den Berg's earlier works, those executed in the1980s, are examined in Chapter Two. The works that are discussed here are: selected works from the Views from the Oasis Series (1983), the Large Oasis Series (1985) and the Sacred Site Series (1985). Reference is also made in this chapter to selected images from van den Berg's series of Invocations (1987). These images are examined primarily in terms of the challenge they present to conventional definitions of landscape and history. In subsequent v.urks of the 1980s van den Berg has presented the landscape more overtly as a symbol of self and personal experience. Central Park: Durban (1987) serves as an early example of work of this type and is. discussed here as it well illustrates a transition in terms of van den Berg's approach to the landscape. In Chapter Three selected vvorks produced by van den Berg in the 1990s are discussed. The works under review here are: the drawings that form part of van den Berg's Mine Dump Project (1994), his installation Men Loving (1996) executed for the Faultlines Project and the sculptural piece created for the !Xoe Site-Specific Project (1988). With these works van den Berg explores not only the marks left on the land by South African recent and colonial history or memory, but also those aspects of South Africa's past which remain hidden- and are unrecoverable. Van den Berg's more recent use of video is also referred to in Chapter Three as his use of, and approach to, this medium may be seen to add a further dimension to his investigations into history. Special attention is paid to the significance of the medium, or kinds of materials used in the creation of these 'HOrks, and condusions are drawn in terms of van den Berg's selection of subject and approach to medium in the period under study.Thesis (M.A.)-University of Natal, Pietermaritzburg, 2000.

Thesis (M.M. (Public Policy))--University of the Witwatersrand, Faculty of Commerce, Law and Management, Graduate School of Public and Development Management, 2013.The study aimed to understand and analyse the ways in which the NFVF as the institution mandated by government to implement its vision for the film industry, interpreted and executed this mandate in its inception years. Using a combination of top-down and bottom-up approaches to policy implementation, this study applied the 5-C protocol developed by Brynard and de Coning (2006) to analyse film policy. The study assesses the process of implementation and the key factors that shaped how the NFVF carried out its policy mandate between 2000 and 2005 largely from the perspective of ‘street-level bureaucrats’ who were the main policy implementation officials. Implementation scholars suggest that in order to understand policy, one is required to follow its journey as it moves through the implementation process, changing its environment, and in turn being influenced by the environment within which it is located. The study’s findings are discussed under various themes that emerged from the interviews and document review. The focus is on the NFVF’s policy content and implications this had on the clarity of its role and mandate. The themes that emerged from the discussion on the NFVF’s policy context indicated that the governance and institutional arrangements for implementation as well as the lack of policy coherence and co-ordination contributed to a difficult operating and implementation environment. Under policy commitment, the discussion pointed to the NFVF’s leadership and institutional style between 2000-2005. The NFVF’s capacity to implement policy was analysed in terms of its available financial resources. Finally, the last section of the study considers the NFVF’s policy clients and coalitions and how they responded to the NFVF‘s implementation of policy.

Faculty of HumanitiesThis paper considers the interaction between the process of producing a documentary video film ‘The Medicine Bag’ and an indigenous knowledge system from the Northern Cape where herbalists or traditional healers are known as ! aixa (Qaiga). These healers use indigenous plants and other raw materials, sounds, rubbing or massaging techniques, incisions and other methods to heal or to harm members of the community. The Schwartz family, Namas who hail from this region, have for many years passed the knowledge and the skills for healing on from generation to generation. For as long as the family can remember, members of each generation, specially gifted and interested in acquiring these skills, have been selected and trained to recognise and harvest medical plants, prepare medicines and apply the various skills required to heal the sick. The raw herbs, potions and medicines have been kept in a medicine bag, made from a tanned springbuck hide. Research for a documentary video to record oral accounts and practices attached to the medicine bag, revealed various themes related to the interaction between oral accounts and the process of recording and transcribing these narratives. These themes included the absence of a fixed storyline or a single ‘correct’ text as is often assumed when one engages with written literature; shifts in meaning that occur when the physical forms of the accounts change as each recording or re-editing acquires a ‘performative aura’ and issues such as the importation of cultural authority and resources on the participants, their active participation in the process of memory and archive creation as well as the impact of the process on the filmmaker/researcher that included an enriched understanding of the scope and possibilities of working with oral texts

M. Tech. Electrical Engineering.Discusses the transport of real time data in WMNs as a challenging problem. The main cause of this problem is transport layer protocols. These protocols have traditionally been used successfully for wired networks. However, their raw implementation in wireless networks has proven to be inefficient, since wireless channels are characterized by a higher Bit Error Rate (BER), Packet Loss Rate (PLR), interference, bandwidth limitations and mobility when compared to wired network channels. Thus, for the efficient transport of real time video in WMNs, transport protocols need to be adapted to be adapted to wireless networks since they were not originally developed for this application.

Thesis (M.Sc. (Agriculture)) --University of Limpopo, 2007The study was designed to outline the production process of a video film with farmers and its use as a tool for agricultural extension with other farmers engaged in similar development processes. The production process of the video film followed five stages namely: (1). Planning stage, where the production idea was discussed between the producer and the director. (2). Pre-production where brainstorming and conceptual framework were made. (3). Production stage was the shooting stage. Production took place at different venues with farmers and extension officers. (4). The editing stage using conceptual framework and Non Linear Editing (NLE) method to organize the video film into sequence; and (5) Distribution to project the video film with farmers in ten rural areas of the Limpopo province. Following the above-mentioned process, an eleven-minute film called Phanda na Vhulimi was produced with farmers, farmer’s leader as the main character and extension officers. Phanda na Vhulimi captured the farmer in her field, during meetings at various venues as a leader and during a public function in the village with provincial leaders. A back voice extensionist supplements the visual information with a description of the support process. In the ten villages the video film Phanda na Vhulimi was then projected to farmers following the subsequent steps: (1) Preparation for projection was a stage for arranging projection venues and setting sound to audible volume. (2) Pre-projection, here the researcher made a short presentation about the study without disclosing the content of the video film. (3) Projection was a stage of playing the video without pausing or talking by the projecting person (researcher) with exception to the viewers. (4) Post projection stage iii was where the video film was discussed with farmers, during this stage the researcher was acting as the facilitator to bring in farmer-to-farmer experience in relation to what was portrayed. After projections, an open-ended questionnaire was used to conduct this research. The raw data collected were analyzed by dividing it into two themes. The themes were divided into subsections as follows: preparation of the video film, reflection by the viewers/participants of the video film and learning during the projection process. The results of the study indicated that people in rural areas of South Africa watch television. There is a culture of shooting still pictures and watching video films but not hiring as they find it expensive, as a result, they borrow or watch with neighbours, friends i.e. other villages or watch family videos produced during special events. With this culture people are used to see pictures-both moving and still, therefore they will criticize less good quality pictures when they come across them. The study discovered that when a video film is produced with characters of the same background targeted audiences associate themselves with the product and feel that it represents them and their activities. These video films can be used as a tool to compliment not to replace the available methods of presentations.

M.Ed. (Media Studies)The task of the school is to use the various school subjects to assist pupils towards maturity. Each subject has a particular role to play in the education occurrence. Physical Education, which is a required subject, has its special role. A number of misconceptions about the educational values of Physical Education need to be cleared up. In addition, the questionnaire which served as a pilot study brought into focus some problems encountered in teaching this subject. In this study, the objectives of Physical Education form the basis of a demonstration of the position occupied by Physical Education in the education occurrence. It is imperative that all these objectives should be realised. There are, however, many teachers of Physical Education who experience difficulty in achieving these objectives on the cognitive, affective, movement, physical and social levels. Video is offered as a means to assist teachers in the attainment of the objectives of Physical Education. Using a detailed plan of a Physical Education lesson, demonstration is given at every phase of the lesson how a video programme can be integrated with the teaching. The unique characteristics of video, which differ from those of any other medium, make it possible for successful integration into every phase of a lesson. Using video, the teacher is placed in a better position to attain the objectives of Physical Education. It is important to realise that video cannot replace all the other educational media used by the Physical Education teacher and that it should not be considered the only solution to problem areas in the teaching of Physical Education.

Full textAbstract:
The integration of technology into teaching and learning has come as new in education. It is a shifting of paradigm from one way of educational thinking to the other. Before entering their classrooms for the first time students already have been using technology devices and educators’ cannot ignore this facts. The South African Ministry of Education has responded to this issue by designing implementation strategies and has mandated all schools in the country to have integrated Technology in the curriculum by 2013. The study anticipated to understand how Educational Video (EV) is used to facilitate learning of mathematics in two Secondary schools in Durban, KwaZulu-Natal Province. The underlying principle was to ascertain the challenges educators encounter in facilitating teaching and learning of mathematics, using EV in two secondary schools in Durban, KwaZulu-Natal Province. A qualitative research approach and case methodology were used to explore these experiences of educators in mathematics instruction. Semi-structured interviews, classroom observations and documents review methods were used to collect data that were analysed and discussed, using the principles of Engagement and Activity theories. Four purposively selected educators and ten grade ten students were interviewed and their mathematics lessons observed. The findings indicated that the integration of video in teaching and learning appears to assist both learners and educators in two schools, and the educators from the two Secondary Schools in Durban, KwaZulu-Natal Province have shown to be comfortable with its use in facilitating mathematics instruction for it enables authentic and higher order thinking in learners by engaging them in complex tasks within collaborative learning contexts. Issues of professional empowerment financial support, and lack of materials, delay the integration of EV in two schools. This would be solved easier if all stakeholders in the education sector were effective in their individual roles for the betterment of education in the whole country.Thesis (M.Ed.)-University of KwaZulu-Natal, Durban, 2008.
