Identifying and finding the impact of Grade 8 learners' alternative conceptions of lightning

Nkopane, Freddy Lehlohonolo 12 March 2007 (has links)
Nkopane, Freddy Lehlohonolo, Student no 0215898Y, MSc, Science Education, Faculty of Science. 2006. / The National Curriculum Statement (NCS) highlights the extensive need for developing insights and respect for different scientific perspectives and a sensitivity to cultural beliefs, prejudices and practice in society. The study wais prompted by the fact that most learners have an African conception of lightning which in most cases is not in agreement with the conventional definition of lightning. The focus of this study was to identify the learners’ conceptions of lightning. Secondly it attempted to elicit, describe and assess the learners’ process of learning Western conception of lightning. And finally, it developed a model of teaching that can be used to help African learners accommodate the two conceptions without contradiction or hindrance. This research utilized qualitative research design to a large extent. A total of 33 participants responded to a questionnaire and 16 were interviewed. In response to question 1, learner’s mentioned that they believe that lightning is a result of witchcraft, it demonstrates the anger of ancestors or it is used by god to demonstrate his existence. These findings suggest that the learner’s African conception is a hindrance to the learning of science because learners’ cultural identity is often very different from the culture of conventional science. Learners experience a type of cultural clash whenever they attempt to learn science meaningfully. A substantial number of learners indicated that the African conception prohibits them from learning the western conception. Further findings suggest that learners do not challenge the validity of the conventional explanation of the origins of lightning. But they believe it is different to the African conception. In summary this research revealed that there is a strong need for educators to be sensitive and knowledgeable about the African learners’ way of thinking. It suggests a teaching model that is aimed at helping educators to deal with misconceptions instead of attempting to change a belief system.

The effect of an argumentation instructional model on pre-service teachers' ability to implement a science-IK curriculum

Siseho, Simasiku Charles January 2013 (has links)
<p>This study investigated the effect of an Argumentation Instructional Model (AIM) on the preservice teachers&lsquo / ability to implement a Science-IK Curriculum in selected South African schools. I examined what instructional practices the pre-service teachers engage in when they introduce scientific explanation and whether those practices influence learners&lsquo / ability to construct scientific explanations during a natural science unit of a South African school curriculum. My study began with a pilot study of 16 pre-service science teachers who completed a B.Ed university module, Science for Teaching, which included an IK component. Data collection for main study took place from 2010 to 2011, and used questionnaires, face-to-face and reflective interview protocols, case studies, lesson plans and classroom observation schedules. I took videos and audios of each of the pre-service teacher&lsquo / s enactment of the focal lesson on argumentation and then coded the videotape for different instructional practices. The study investigated firstly, what currently informed teachers&lsquo / thinking, knowledge and action of IK. Secondly, the research questioned how teachers interpreted and implemented IK in the science classroom. A sample of the three pre-service teachers were followed into their classrooms to investigate how they specifically implemented Learning Outcome Three using argumentation instruction as a mode of instruction and what approaches relevant to the inclusion of IK were developed. The study found that the three pre-service teachers used three very different approaches through which IK was brought in the science curriculum. An assimilationist approach, that brings IK into science by seeking how best IK fits into science. A segregationist approach that holds IK side-by-side with scientific knowledge. Lastly, an integrationist approach makes connections between IK and science. The approaches developed by the pre-service teachers were found to be informed by their biographies, values, cultural backgrounds and worldviews. Meticulously, the study explored how shifts were being made from a theoretical phase at the university where the pre-service teachers engaged IK to an actual phase of implementation in their school science classrooms. Finally, I attempted to explain why the pre-service teachers interpreted and implemented IK in the way they did.</p>
