Philosophiae Doctor - PhD / This study is an extension of work previously performed by Linder et al. (1997). It sought to explore university Physics I tutors’ conceptualization of Physics I tutorials and their conceptualization on issues relating to observations and interactions during tutoring, through involvement in a reflective practicum. The study was premised on socio-cultural constructivism, co-operative learning, situated learning theory and reflective practice.The study developed over two phases. In phase one the reflective thinking processes of the tutors were explored. Upon reflection on the literature the research context was further developed which allowed a final exploration into the tutors’ conceptualisations of the Physics I tutoring context. During this final exploration, i.e. the second phase, tutors were exposed to an organized, longitudinal sensitisation session, i.e. tutor-training over a period of nine months. Tutors were introduced to co-operative learning and the various processes of reflective practices namely, follow-me, modelling and joint experimentation, reflection-inaction and reflection-on-action.Analysis of the data was carried out using the phenomenographic research perspective. Ananalysis of the categories of description was used to demonstrate the tutors’ ability to reflect,based on their conceptual understanding of and interactions during the physics tutoring. These categories favoured the development of extended criteria to enhance reflection amongst physics tutors. These extended criteria were then used as a basis to suggest a model to support reflection amongst Physics I tutors.

This study examined the differences in achievement between groups exhibiting different cultural dimensions in a particular online instructional environment. Variables were measured concerning the relationship between instructional environments, cultural dimensions and online learner preference. The subjects of this study were a representative sample of groups of graduate students from different cultures. The instrument was composed of a treatment that was represented across two instructional environments. A web-based tool measured participant?s cultural dimension, recall, transfer of knowledge and learning preference. A 2 x 2 x 2 ANOVA analysis method was used to examine the effects of individualism and collectivism on learner preference and achievement (recall, transfer). Significance in transfer measures was found. This indicated deep understanding of materials for collectivist participants. Correlational analysis revealed significance between cultural dimension and learner preference for instructional methods. Findings were consistent with the body of literature on cross-cultural psychology. / Ph. D.

Magister Educationis - MEd / This study explored the dialogical argumentation instruction approach to determine whether it enhanced grade ten learners‟ understanding of the chemical equation concept. Toulmin‟s argumentation pattern and the contiguity argumentation theory underpin this study and was used to construct the dialogical argumentation instruction methodology, which was used as the intervention strategy. Information and communication technology and computer-assisted learning were used as contextual environment for this study. This study is located in the interpretive paradigm and the data was collected and analysed using both qualitative and quantitative methods based on a quasi-experimental research design model. A survey questionnaire, open-end and fixed choice questionnaires and a chemistry achievement test was used to collect data from a high school in the Western Cape Province

<p>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 &ldquo / Culture Secondary School&rdquo / 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 learners&rsquo / pre- and post-test conceptions of fermentation with special reference to traditional beer or &ldquo / Umqombothi&rdquo / , an Attitudes to Science (ATS) questionnaire which was used to find out the learners&rsquo / worldviews, a Science Achievement Test (SAT) which was used to assess the learners&rsquo / 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&rsquo / 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 gatherred were both analyzed in terms of qualitative and quantitative descriptions.</p>
