What ‘ideas-about-science’ should be taught in school science? A chemistry teachers’ perspective

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.     

A mixed-method study of EFL teachers’ Internet use in language instruction

Information and communication technology has affected language instruction in Taiwanese higher education. Varieties of assorted Internet tools are incorporated in educational settings to engage students in learning. To facilitate the improvement of teacher preparation for Internet use, it is important to study the factors influencing teachers in integrating the Internet into their instruction. A concurrent mixed-method approach is employed in this study. Both quantitative and qualitative results show that teacher training is crucial for Internet-integration instruction by the teachers of English as a foreign language (EFL) in Northern Taiwanese higher education institutions. Continuous professional development focused on technology application in language instruction is imperative.
