This study was based on the Science and Indigenous Knowledge Systems Project (SIKSP) at the School of Science and Mathematics Education, University of the Western Cape. The project seeks to enhance educators’ understanding of and ability to implement a Science-IKS curriculum (Ogunniyi, 2007) through using the theoretical framework of argumentation (Toulmin Argument Pattern) to the extent that learners would value the significance of both worldviews. This study sought to find the effects of an Argumentation-Based Instruction on grade 10 learners’ understanding of the causes of pollution at a river site. Since the integration of Science and IKS are envisaged by Curriculum 2005 (C2005), two theoretical argumentation constructs have been used namely, Toulmin’s (1958) Argumentation Pattern (TAP) and Ogunniyi’s (1995) Contiguity Argumentation Theory (CAT).

Magister Educationis - MEd (Mathematics and Science Education) / The study catered for empirical and metaphysical dimensions of science and IKS. The study employed a quasi-experimental design as well as a qualitative research design. Two cohorts of students from a fictitiously named Culture Secondary School have been used in this study. The list of instruments for data collection were as follows: Conceptions of Fermentation (COF) questionnaire which was used to elicit learnerss pre- and post-test conceptions of fermentation with special reference to traditional beer or Umqombothi an Attitudes to Science (ATS) questionnaire which was used to find out the learners' worldviews, a Science Achievement Test (SAT) which was used to assess the learners' generalised knowledge of fermentation, a classroom observation schedule as well as a focus group interview schedule to gather additional qualitative data. All the instruments were in English with all technical and difficult terms in both English and isiXhosa (the learners’ home language). Both groups were exposed to Science/IKS-based lessons. The only difference between the two groups was that, the experimental group (E group) was exposed to a Dialogical Argumentation Teaching Model (DAIM) and the comparison group (C group) to a traditional teaching approach. The data gathered were both analyzed in terms of qualitative and quantitative descriptions. / South Africa

Text in Afrikaans / Hierdie studie ondersoek die behoeftes van Afrikaanse televisiekykers aan Afrikaanse televisieprogramme te midde van die veranderinge wat sedert demokratisering aan die Suid-Afrikaanse medialandskap plaasvind. Hierdie behoeftes word ondersoek by wyse van 'n gevallestudie ender graad 10-leerders in Pretoria. Die gebruike- en bevredigingsbenadering dien as teoretiese onderbou vir die studie en die invloed van 'n aantal veranderlikes word ondersoek. Hierdie veranderlikes is televisiegerig (inhoud, aanbod en struktuur van Afrikaanse programme), tegnologiegerig (nuwe mediategnologiee socs satelliettelevisie en die Internet) en kykergerig (sosio-kulturele, persoonlike en demografiese faktore). Die studie bevind dat daar 'n verband is tussen hierdie veranderlikes en respondente se behoeftes aan Afrikaanse televisieprogramme. Die studie bevind dat Afrikaanse programme nie respondente se behoeftes bevredig nie. Nuwe mediategnologiee verbreed respondente se sosio-kulturele horlE;onne sodat hulle gemaklik met programme in Engels omgaan. Te midde van die toenemende aanbod van oorsese programme in Engels, neem die behoefte aan Afrikaanse programme af. / This study investigates the need for Afrikaans television programmes among Afrikaans viewers in the changing media environment in South Africa. Needs are studied by means of a case study among grade 10 learners in Pretoria. The uses and gratifications approach serves as the theoretical framework of the study and a number of variables are investigated. These variables are television driven (supply, content and structure), technology driven (new media technologies such as satellite television and the Internet) and viewer driven (socio-cultural, personal and demographic factors). The study finds that there is a connection between these variables and the need for Afrikaans programmes among respondents. The supply, content and structure of Afrikaans programmes do not gratify respondents' needs. New media technologies broaden respondents' socio-cultural horizons, enabling them to comfortably watch English programmes. Amidst the increasing supply of overseas programmes in English, the need for Afrikaans programmes is diminishing / Communication Science / M. A. (Kommunikasiekunde)

The South African education system has been evolving since the country became democratic in 1994 and a number of curriculum reforms have been introduced within a short space of time. These reforms revolve around power and control and therefore, Bernstein’s concepts of classification and framing form the conceptual framework for this study. This study attempts to give a picture of what is currently happening in schools pertaining to the implementation of the grade 10 Life Sciences (LS), Business Studies (BS), and Engineering Graphics and Design (EGD) Curriculum and Assessment Policy Statement (CAPS). The dual aim of this study was to find out educators’ understanding and interpretation of the CAPS that can be observed in their teaching practice and to establish how decisions on subject content (selection, sequencing and pacing) are made. Also of importance was to determine whether educators view and treat their subject as unique or as similar to other subjects. The study used a qualitative approach, using case study design. Observations were used as the main method for data construction. Four LS, BS and EGD educators from four different schools were observed teaching the same class for five consecutive lessons. Thereafter, these educators were interviewed. For triangulation purposes, learners and the subject advisor were participants in this thesis. For this purpose a group of ten randomly selected learners from observed classes per subject and school were requested to complete a questionnaire and the LS, BS and EGD subject advisors were interviewed. The subject advisors insisted that educators follow the CAPS so that learners would be able to write common assessment tasks at the end of each term. Although educators claimed that they were following the CAPS regarding content selection, sequencing and pacing, observations showed that educators were not following the CAPS document. The findings suggest that well coordinated interventions are required to support and monitor educators’ practice. / Curriculum and Instructional Studies / D. Ed. (Curriculum Studies)
