Abstract


Ergonomics is the discipline which focuses on the impact of human needs and capabilities on the design of technological systems for the purpose of promoting harmonious cooperation between humankind and technology. In computer studies, it studies the interaction between pupils and the computer environment in order to promote learner well-being. The future health and learning opportunities of learners are at risk if computer skills are not mastered in a safe and healthy environment. Risks associated with computers have increased because of the increased time young people spend with their computers both at school and for recreation. The use of computers as teaching aids has also increased. The purpose of this article is to report on research that was conducted in computer labs in high schools in South Africa about the establishment of an ideal ergonomic environment in order to assure optimal learner security in the computer labs. Caring supervision is a prerequisite for optimal teaching and learning. Security expresses itself in a classroom environment in terms of pedagogical outcomes as well as the physical security and well-being of the pupil. The provision of security in the computer lab is not restricted to the present; it is also prospective in that it is aimed at the future security and health of the pupils. A computer environment that does not comply with ergonomic norms could harbour a number of health risks for students, including muscular-skeletal injuries due to an incorrect posture, also headaches caused by conditions such as a glaring screen or insufficient lighting. Pupils could also become victims of safety hazards such as electrical shorts and fires caused by electric cables lying on the floor, and faulty appliances. There are a number of guidelines available with respect to the design of a computer lab, amongst others concerning equipment and furniture, the support of wrists, the use of the mouse, keyboard, non-reflecting screens, the height of the screen, the adjustability of apparatus, lighting, a good view of the projector screen and white board, the document stand, and the size of the computer stand.

Indien rekenaarlokale in skole nie aan die eise van ergonomiese geborgenheid voldoen nie, kan dit tot groot nadeel strek vir almal wat daarby betrokke is. Vir die leerders kan dit algemene gesondheidsrisko's soos skeletale afwykings, hoofpyn en sigprobleme inhou, wat dikwels eers in die leerders se volwasse jare begin realiseer. Daarbenewens kan hierdie gesondheidsprobleme wat uit sulke swak ontwerpte lokale voortspruit, tot gevoelens van onsekerheid en niegeborgenheid by die leerlinge aanleiding gee. Vir die betrokke onderwysers en die skool as sorgsame toesighouers van die leerders, kan 'n verwyt van nalatigheid en die moontlikheid van aanspreeklikheid vir skadevergoeding ontstaan. In 'n kwalitatiewe interpretivistiese studie by al die hoërskole met rekenaarlokale in een bepaalde streek in die Noordwes-provinsie, het dit aan die lig gekom dat nie een van hulle ergonomies korrek ontwerp en bestuur is nie. Voorstelle word gemaak vir die dringende regstelling van hierdie probleem. Die eerste stap is om goedkoop en voor die hand liggende maatreëls toe te pas, deur byvoorbeeld net 'n kussing op 'n stoel te plaas, die rekenaarskerm op 'n paar ou boeke te plaas om dit op te lig, kabels en alle papier wat op die vloer lê en 'n brandgevaar kan veroorsaak, te verwyder. Van die ander aanbevelings wat gemaak word, behels groter betrokkenheid vanaf die kant van die provinsiale onderwysdepartement, meer fondse vir die korrekte inrigting van lokale en groter bewusmaking by onderwysers, skoolhoofde en leerders.
