The purpose of this research was to investigate the role that science education can play both in facilitating and in enhancing the delivery of environmental education at South African schools. The theoretical links between science education and environmental education were examined. This was followed by a practical investigation which involves the researcher conducting interviews with educators of natural science in order to determine their perspectives on the relationship between science education and environmental education. The results of the research indicate that science education has tremendous potential for incorporating and enhancing the delivery of environmental education. However, this potential is not being fuIly realised due to a number of limiting factors. It is, therefore, imperative that the education authorities take immediate action to rectify this situation so that the synergy between science education and environmental education comes to fruition. / Science and Technology Education / M.

AIM AND OBJECTIVES The investigation aimed to determine how the learning of the life sciences is facilitated (mediated) in special schools for blind learners and to establish how the lessons learnt from this experience could be implemented to the advantage of blind learners in the Senior Phase and Further Education and Training Band in inclusive Outcomes-based education settings. METHODOLOGY Educators and blind learners were interviewed through the use of the Qualitative Inquiry methodology as well as its techniques and strategies for data gathering. Analysis of the transcripts resulted in the development of themes/codes discussed in the research investigation. RESULTS Educators spent a good amount of time and effort with blind learners in the biology and life sciences classrooms. It appeared as if the pastoral role of the educator predominantly exceeded the teaching of biology and life sciences to these learners. Further, it became evident that the emphasis did not fall strongly enough on the achievement of the outcomes envisaged with the biology curriculum but more on the establishment of a caring and supportive classroom environment. CONCLUSIONS Biology and other life sciences subjects have much potential for the blind learners in South Africa but they are not offered at some of the schools or efficiently mediated due to educators’ reluctance, lack of knowledge and resources. Learning mediation strategies to make biology and life sciences more accessible to blind learners could be explored. / Thesis (PhD (Curriculum and Instructional Design and Development))--University of Pretoria, 2006. / Curriculum Studies / unrestricted

Over the last few years, the use of the web and simulation technologies in school education has become widespread. The purpose of this study was to compare the impact of a web-based Virtual Lab (WVL) environment with that of traditional educational experience in relation to conceptual understanding and science process skills in natural science for fourth grade primary school students. Using an instructional design model, the author developed a WVL; the design consisted of 3D animations and interactive experimental activities. The research instruments for the study were also developed; two online pre/post tests on conceptual understanding and science process skills were used to collect data. The sample used in the study consisted of 70 students from two primary language schools in Mansoura city, Dakahlyia Governorate, Egypt. The sample was divided into an experimental group and a control group. The author used an experimental design wherein the experimental group was exposed to the WVL, while the control group studied in a traditional setting and performed related activities. The pre-test results indicated that the entry-level for conceptual understanding in science and science process skills of both groups of students were equal, which guaranteed the reliability of the research. The findings of the post-test highlighted the following points: (a) Students in the experimental group had significantly higher mean scores in conceptual understanding especially in two of cognitive levels. (b) The experimental group performed better in science process skills, especially in five of these skills. (c) There was no significant difference in the performance of boys and girls within the experimental group for science process skills. (d) The estimation of the effect sizes (indication of the level of difference between the post-test scores of the experimental and control group) revealed that, the effect size was large for two skills, medium for three skills, and small for only one skill. In conclusions, the WVL provided considerable support for fourth grade students and helped them to improve their conceptual understanding in science and science process skills. These results go beyond previous research results, which did not focus on very young learners. The use of WVL contributed considerably in elevating learning outcomes; the results provided an empirical evidence of the advantages of web-based learning (WBL) for education policy makers. / In den letzten Jahren hat sich die Verwendung der Web-und Simulations-Technologien in der Schulbildung weit verbreitet. Der Zweck dieser Studie ist es, die Auswirkungen einer web-basierten Virtual Lab (WVL) Umgebung mit der traditionellen Lehr-Erfahrung in Bezug auf das konzeptuelle Verständnis und wissenschaftliche Prozessfähigkeiten in den Naturwissenschaften der vierten Klasse der Grundschulstudenten zu vergleichen. Mit einem didaktischen Design-Modell entwickelt der Autor ein WVL, gestaltet 3D Animationen und interaktive experimentelle Aktivitäten. Die Forschungsinstrumente für die Untersuchungen wurden auch entwickelt, zwei Online-Pre/Post-Tests zum konzeptionellen Verständnis und wissenschaftlichen Prozessfähigkeiten wurden verwendet um Daten zu sammeln. Die Uuntersuchungs besteht aus 70 Studenten aus zwei primären Sprachschulen in Mansoura Stadt, Dakahlyia Governorate, Ägypten. Diese wurden in eine experimentelle Gruppe und eine Kontrollgruppe aufgeteilt. Der Autor verwendet ein experimentelles Untersuchungsdesign, wobei bei der experimentellen Gruppe die WVL eingesetzt wurde, während die Kontrollgruppe in einem traditionellen Rahmen studierte. Die Pre-Test Ergebnisse zeigten, dass des Anfangsstadium des konzeptuelles Verständnisses von Wissenschaft und wissenschaftlichen Prozessfähigkeiten beider Gruppen von Studenten gleich sind. Die Ergebnisse nach dem WVL-Einsatz haben folgende Punkte hervorgehoben: (A) Studierende in der experimentellen Gruppe haben signifikant höhere Mittelwerte im konzeptionellen Verständnis vor allem in zwei der kognitiven Ebenen erreicht. (B) Die experimentelle Gruppe hat in den wissenschaftlichen Prozessfähigkeiten besser abgeschnitten, vor allem in fünf von diesen Fähigkeiten. (C) Es gab keinen signifikanten Unterschiede in den wissenschaftlichen Prozessfähigkeiten von Männern und Frauen innerhalb der experimentellen Gruppe. (D) Die Abschätzung der Wirkung des WVL-Einsatzes durch die Höhe der Differenz zwischen dem Pre- und Post-Test-Noten hat ergeben, dass die Wirkung für drei der Fähigkeiten mittelmäßig ist, für zwei Fähigkeiten sehr groß und nur für eine Fähigkeit klein ist. Die Schlussfolgerung ist, dass die WVL beträchtliche Unterstützung gewährt und hilft den Studenten der Klasse vier, ihr Verständnis für die Begriffe der Wissenschaft und der Prozessfähigkeiten zu entwickeln. Dieses Ergebnis geht weit über die bekannten Veröffentlichungen auf diesem Gebiet hinaus. Die Ergebnisse dieser Studie vertiefen das Verständnis über Lernergebnisse des Virtual Lab und sind eine Evidenz für die Vorteile von Web-Basiertem Lernens (WBL) mit Relevanz für politische Entscheidungsträger, auf diesen Ausbildungsgebiet.

Grade 12 learners in one Namibian secondary school participated in a study of science process skills implied in their International General Certificate of Secondary Education (IGCSE) physical science syllabus. The study aimed at finding out learners’ ability to identify science process skills in their physical science syllabus, criteria used to identify skills and whether any relationship existed between learners’ achievement in performing skills and learners’ ability in identifying the skills. Four physical science syllabus topics were taught. Learners performed and identified science process skills in learning and assessment tasks. A One Group Pretest-Posttest research design was used in a combined qualitative and quantitative research method. Data revealed that learners identified science process skills. Science processes performed during learning experiences were used as criteria to confirm presence of the skills. Learners’ achievement increased in performing and identifying science process skills after intervention activities. There seemed no relationship between learners’ achievement in performing and learners’ ability in identifying science process skills. / Science and Technology Education / M. Ed.

This study was motivated by the lack of in-service training in cooperative learning and science process skills whereas both are emphasized in the new natural sciences curriculum. The aims of the study were to determine the influence of cooperative learning on the development of science process skills. Two classes were selected from two rural schools for inclusion as case studies of this research. These classes were taught using the Jigsaw and Group Investigation methods of cooperative learning respectively. Pre- and post-tests were administered on the two classes and the influence of these methods on learners' achievement on four process skills were determined. Mixed results were found with regard to the influence of the two cooperative learning methods on the development of learners' process skills of observation, controlling variables, graphing and experimenting. / Educational Studies / M.
