    The use of pod casting revision lectures in improving learners' academic performance
    (Vaal University of Technology, 2014-04) Rankapola, M. E.; Conradie, P., Dr.
    The majority of research studies completed on podcasting technology focused on the acceptance of podcasting technology in the educational settings and the challenges that it poses for higher education institutions and instructors. Very little interest has been accorded to the effect that podcasting could have on the learners‟ academic performance. Utilizing a quasi-experimental non-equivalent group posttest, a wide used research method in the education discipline, the relationship between podcasting technology and academic performance, is investigated. The quasi-experimental was performed based on data collected over a period of 12 months, in which a non-random sample of 150 learners was taken from a population group of 350 management and entrepreneurship undergraduate learners at the Tshwane University of Technology. The sample was separated into two groups, namely the experimental group of 75 students, and the control group of 75 students. Both groups were offered the same subject by the same instructor. Control group learners are learners who have already completed the subject in the first semester before the podcasting technology was introduced in the subject. The experimental group learners are learners who have completed the subject through the support of podcasting technology. The assessment marks for four formal tests of the two groups were compared by means of a t-test to determine the effect of the intervention. The outcomes of the study showed an increase in the overall mean score of the experimental group in comparison to the mean score of the control group. The number of students obtaining distinctions also increased, compared to the control group. These considerations possibly indicate a positive relationship between the availability of podcast lectures and academic performance.

    The use of visualization of corporate data in strategic Information and Communications Technology industrialization
    (Vaal University of Technology, 2013-02-20) Dippenaar, Francois; Conradie, P., Dr.
    Global companies tend to have problems in knowing the systems, assets and resources they have within their global footprint. This tends to be costly to the company as there tends to be purchases of the same systems, assets and resources that are already available in another business unit or department within the company. This leads to money being wasted on research, procurement and/or training, to name a few. You can't manage what you don't know about. This thesis will show how the visualisation of corporate data is possible and has sustainable benefit to a company. Knowing the status of the Information and Communications Technology (ICT) environment in a company at some point in time is crucial in planning and implementing strategies with the future in mind. Global View, which will be explained in this thesis, is key in facilitating the extracting of information from all the sites globally and presenting the information in a logical and structured way. Information gathering from these sites using Global View needs to be done in an auditing fashion with the focus on accurate and precise information with an option which would allow the audit to be a continuous and automatic process. Global View is a tool to facilitate the implementation of ICT Industrialization through a process of gathering the relevant ICT information worldwide with specific reference to each site. Global View displays the relevant information from systems, assets, resources and environments in an easily accessible format. The functionality that is built into the concept in this thesis is the geographical and geospatial orientation which is linked to the relevant sites as well as time references related to Greenwich Mean Time to make users aware of differences in time when communicating with people in other countries either individually or multiple sites simultaneously.
