| Abstract: | The objective of this study is to facilitate in-service chemistry teachers’ understanding of nature of science and what ‘ideas-about-science’
can be included in the classroom. The study is based on 17 in-service teachers who had registered for a 11-week course on
‘Epistemology of Science Teaching’ as part of their Master’s degree program. The course is based on 17 readings drawing on
nature of science and its critical evaluation. Course activities included written reports, classroom discussions based on
participants’ presentations and written exams. Based on the results obtained this study has the following educational implications:
(a) Experimental data need to be interpreted carefully due to underdetermination of theories by data; (b) Kuhn’s normal science
manifests itself in the science curriculum through the scientific method and wields considerable influence; (c) Trilemma posed
by Collins (Stud Sci Educ 35:169–173, 2000), viz., creation of new knowledge ⇔ Kuhn’s normal science ⇔ teaching nature of
science, provided a big challenge and was thought provoking; (d) Of the different aspects of nature of science suggested by
experts, these teachers endorsed the following as most important: Creativity, Historical development of scientific knowledge,
Diversity of scientific thinking and Scientific method and critical testing; (e) With respect to the contradiction between
the positions of Lederman et al. (J Res Sci Teach 39:497–521, 2002) and Osborne et al. (J Res Sci Teach 40:692–720, 2003),
few supported the position of latter, viz., inclusion of scientific method in the classroom and a majority supported the former,
viz., scientific method as a myth; and (f) Participants were critical of the present stage of research with respect to the
scientific method and suggested the introduction of history, philosophy and epistemology of science to counteract its influence. |
