<p>This thesis was based on a larger international comparative study called the ROSE (Relevance of Science Education) project. The study investigated the affective factors pupils perceive might be of relevance for the learning of science and technology using the ROSE survey questionnaire, and was aimed at providing data that might form part of an empirical basis for local adaptation of the science curriculum.</p>

The problem of this study is to determine the relationships between (1) growth in interest and achievement of high school science students and (2) attitudes, preparation, and experience of science teachers. The study encompasses grades nine through twelve, inclusive, in a sample of Texas accredited public high schools.

The purpose of this study is to investigate the effects of using verbal analogies in teaching ninth-grade physical science. The experiment is designed to determine if teaching by analogies is more effective than conventional methods of teaching, and to ascertain the effect of analogies on achievement for different ability levels in different subject areas of physical science.

The purpose of this study was to identify and analyze secondary science education curriculum and instruction trends for the period 1953-1992 by using the technique of content analysis to examine a representative portion of journal articles and policy statements in secondary science education. Two major science publications, The Science Teacher and Science Education, were selected for analysis.

M.Ed. (Education) / This study is an analysis of Grade 9 Natural Sciences textbooks for their representation of the nature of science. The textbooks analysed are CAPS compliant and approved by the Department of Basic Education. Like any other modern education system in a democratic dispensation, the South African education system has undergone several curricular changes post- independence (1994). These changes have been due to, but not limited by, factors pertaining to political and economic reforms. Curricular revisions have spanned a period of almost 20 years, commencing with Curriculum 2005 (C2005) to the current revised Curriculum and Assessment Policy Statements (CAPS). Science curriculum documents subscribe to the tenets of the nature of science (Lederman, 2007). Bell (2008) suggests that science is best defined by its characteristics, otherwise known as the tenets of NOS. Eleven key aspects of NOS that are intricately related to the basic tenets of science derived by Lederman (2007) form the analytical framework used in this study. The aspects are: Empirical; Inferential; Creative; Theory-driven; Tentative; Myth of the scientific method; Scientific theories; Scientific laws; Social dimensions of science; Social and cultural embeddedness of science and Science vs. pseudoscience. These aspects further formed a detailed scoring rubric to record the extent to which NOS is represented in the units of analysis, which comprise complete paragraphs, activities, worked examples, figures with captions, tables with captions, charts with captions, and marginal comments of the sampled topics ...

A research report submitted to the Faculty of Science in partial fulfilment of the requirements for the degree of Master of Science. Johannesburg, 2013. / The integration of indigenous knowledge into the mainstream science curriculum has been advocated for by science educators around the world. The Revised National Curriculum Statements (RNCS) for Grades R-9 (Natural Sciences) clearly advocates for the incorporation of indigenous knowledge into the science curriculum. They stipulate that learners must learn science within the context of their historical, societal and cultural knowledge and values. It is important that learners should understand other systems of knowledge, such as indigenous knowledge systems (IKS). The underlying assumption is that teachers can help learners integrate science and indigenous knowledge but in order to do that, they too must have adequate knowledge and understanding regarding the two thought systems. The challenge is that some teachers are not well informed about the varying indigenous knowledge that typifies the multi-cultural situation in South African classrooms as they have been schooled in western science The study aimed at eliciting learners‟ and teachers‟ knowledge about traditional medicinal plants and their attitudes towards integration of that knowledge into the science curriculum. This was with a view to exploring any differences or similarities between the views of teachers and learners. A case study was carried out at a secondary school in Meadowlands, Soweto. A sample of 36 Grade 9 learners and 10 teachers of Natural sciences was selected using the convenience sampling technique. Structured pictorial questionnaire was used to collect data from both teachers and learners. Field notes were taken during a class debate on the effectiveness of traditional medicines versus western medicines. Unstructured follow up interviews (5 learners- group interview and 3 teachers-individual) were performed on selected participants to probe further their responses to the questionnaire. A ROSE1 type questionnaire was used as a follow up when learners were in grade 10 (2013). Analysis of the findings showed that a majority of learners and teachers that participated in this research have opposing attitudes regarding the need to integrate knowledge about traditional medicinal plants into the science curriculum. The 1ROSE-Relevance Of Science Education, a questionnaire distributed in many countries by Prof Svein Sjøberg, ILS, University of Oslo, Norway. learners in this study had generally more knowledge that the teachers about traditional medicinal plants. The majority of learners are willing to learn about indigenous knowledge (IK). Nine teachers out of ten in this study were generally less enthusiastic about teaching about traditional medicinal plants. In light of the findings it is recommended that teachers need to have in-house training in so far as the methodological aspects of integrating components IK into the science curriculum relate. This may go a long way in limiting conceptual conflicts amongst the learners.

A thesis submitted to the Faculty of Science, Unjversity of the Witwatersrand, Johannesburg, in fulfillment of the requirements for the degree of Doctor of Philosophy in Science. March 1995 / This thesis reports on school teaching and learning problems in the area of chemical re&ctivity and on an attempt to overcome some of these problems with an in-service course for teachers. rhase 1 of this research was a study of the conceptions of aspects of reactivity, rates of reaction and chemical equilibrium held by secondary school students. The nature and origin of the conceptual di:Eficltlties, i.n the above areas were investigated. The concepts of ret,ctivity and reactivity se.rd.e s are formally introduced at a standard 8 level. These concepts form a springboard for the understanding of more formal quantitative worl< done i.n rates of reaction and chemical equilibrium at a standard 10 level. Two multiple-choice questionnaires, a reactivity qUestionnaire and a i'a'Ceand (.,quilibrium qUestionnaire, were designed to probe for the nature and ori9i.n of views held )y st<mdard 8 & 10 students respectively. The views of both the standard 8 & 10 students on aspects of react~vity and reactivity series Were investigated using the reactivity ql.ltlstionnaire.The views of a sample of 'Jtandard 8 students were also probed during interview sessions conducted at selected schools. standard 10 students views about concepts related to aspects of rates of reaction and chemical equilibrium, were also investigated

The major problem of this study was to compare the views of the role of the student in a science class as reported by college science educators and secondary science teachers of grades 6-8 and of grades 9-12. Analysis of individual items. The Q-sorts indicate that all groups in this study recommend greater emphasis on student activities, student discovery, student questions, teacher accepting students' new ideas and viewpoints, student freedom to ask any science question, student enjoyment of science, more time spent in doing things other than listening, student ease in getting equipment, student revealing likes and dislikes in science, student maintenance of science equipment and student use of laboratory equipment.
