N2  - The main research aim of this Ph-D thesis is to develop students?understanding of the nature of science on the background of Alexander von Humboldt's legacy for Grade 5 and Grade 6 classrooms in Baden-Württemberg schools. The Ph-D research questions are: 1.What conceptions do students of the age group 10-12 regarding the nature of science hold? 2.Does students? understanding of science change as a result of discovery-based science activities taken from Alexander von Humboldt? scientific observations during his expedition to Latin America between 1799-1804? If yes, in what way? This was done by: 1.Gathering background information about students? images of scientists and how they work. 2.Designing the most appropriate learning environment for improving their understanding of science. At the beginning of the intervention study, Humboldt?s life was used as a stimulus of student?s thoughts about science at. Students were put in the same situation of a scientist: posing a question about a theme of their interest, designing and realizing an experiment in order to satisfy their curiosity. By doing so, students? understandings of the construction of scientific knowledge would be improved. After a preliminary study between June and July 2002 at the Bammental Gymnasium, a case study took place from March till July 2003 at the Realschule Linkenheim for students of Grade 5. Students? epistemologies about science and scientists at the Realschule Linkenheim were collected by using the current trends in science education research: pre- and post-questionnaires, classroom observation, pre- and post- interviews, the Draw-A-Scientist-Task and portfolio work. This intervention study was realized in 26 school sessions and all the work sessions were also video taped. Students? views about their actual nature of science aspects were characterized and coded using a framework drawing on the following areas: characteristics of scientists, history of science and the epistemology about science and scientists. Finally, students were asked to write about their learning process by using portfolios. As to the recommendations: This study suggests that in order to develop some aspects of the nature of science, students need a free space at school to realize hands-on inquiry and a trained teacher who can translate to his students besides content knowledge, the nature of knowledge and the historical evolution of scientific knowledge.
