Improved quality control Utilising the videos as a single point of knowledge transfer confirms that the curriculum outcomes are controlled. For example, with numerous groups of students having to perform the same practical tasks, the use of tutors and other assistance is necessary. At times there is a breach in the knowledge levels of support staff, whereas the videos are certain to cover the curriculum correctly. Community service The public nature of online video sharing brings with it additional societal benefits. Judging by the popularity of the five videos and the continuous public requests for more videos, it could be argued that there is a need for tutorial-based engineering education that is freely available to the wider community. Since universities are in service of humanity, educational videos made freely available are an ethical imperative and a form of community service. Figure 6: Example of text overlays for wiring a video on how to wire a South African plug top. The text supports what is shown in the image. Since students were provided with the videos prior to performing their practical work in the laboratories, the finding was that they could perform the laboratory tasks more quickly and with improved skill.
