Abstract in English, Tswana and Xitsonga / Education officers based at science centres and museums play a significant role in teaching the visiting learners science. However, little is known about their teaching practices at these centres. The purpose of this study was to investigate the teaching practices of education officers when teaching science in a science centre environment. The focus of this study was on the education officers’ knowledge and instructional strategies used in teaching science at a science centre in Pretoria, Gauteng province. A qualitative case study approach was used. Data was collected from the three participating education officers using semi-structured interviews and observations. Data was analysed separately from each case using education officers’ knowledge framework guidance. The findings from this study indicate that although education officers have shown an adequate content knowledge in teaching science at the science centre their teaching method was teacher-centred and non-interactive and show-and-tell strategies were more common amongst the education officers. The study also revealed that education officers did not use their resources/exhibits effectively in teaching science. It is recommended in this study that intensive training of education officers is required before they can interact with the visiting learners. / Baokamedi ba thuto ba kwa mafelong a maranyane le dimusiamo ba tshameka karolo e e botlhokwa mo go ruteng barutwana ba ba etileng dithuto tsa maranyane.

Text in English, with summaries and keywords in English, Sesotho and Afrikaans / This study is an enquiry into how The educator’s new clothes by Mark Rautenbach is an example of site-specific art. The aim is to demonstrate how boundaries in TENC become blurred between site-specific performance, other art forms, and every-day activities. The key concepts explored are: Rautenbach’s approach to the concept of site, the connections that develop between his performance and each site that he travels to; his use of the art gallery and viewer participation. Through literature study relevant theory is explored, and several arguments are applied in a selective manner to my analysis of TENC. Various International and South African site-specific artworks are discussed as an indication of how site-specificity can be applied in alternative ways. In October 2017 I installed GREENER?, a site-specific exhibition in the UNISA Art gallery. The works on the show underline the theoretical findings and highlight the flexible application of theory relating to site-specificity. / Dinyakišišo tše ke phatišišo mabapi le seo se dirago bokgabo bja The educator’s new clothes (TENC) ka Mark Rautenbach go ba mohlala wa bokgabo bja lefelong le itšego.

Die oogmerk is om aan te toon hoe die grense tussen plekspesifieke uitvoering, ander kunsvorme en daaglikse bedrywighede vervaag. Die kernkonsepte wat verken word, is Rautenbach se beskouing van die konsep van plek, die verband tussen sy uitvoering en elke plek waarheen hy reis, sy aanwending van ʼn kunsgalery, en kykerdeelname. Die tersaaklike teorie word aan die hand van ʼn literatuurstudie verken, en ʼn aantal argumente word op selektiewe wyse op my ontleding van TENC toegepas. Verskeie internasionale en Suid-Afrikaanse plekspesifieke kunswerke word bespreek as ʼn verkenning van hoe plekspesifisiteit op ander maniere toegepas word. Ek het in Oktober 2017 ʼn plekspesifieke uitstalling met die titel GREENER? in die Unisa Kunsgalery gehou. Die werke wat uitgestal is, onderstreep die teoretiese bevindings en vestig die aandag op die buigsame toepassing van die teorie in verband met plekspesifisiteit. / Art History, Visual Arts and Musicology / M.V.A.
