Nature Of Science: Examining Science Teachers’ Knowledge And Their Instructional Practices, Sharon Bramwell-Lalor
Nature Of Science: Examining Science Teachers’ Knowledge And Their Instructional Practices, Sharon Bramwell-Lalor
Australian Journal of Teacher Education
This case study focused on a university teacher-education course that included NOS content. An adapted questionnaire was used to collect quantitative data on 83 secondary science teachers’ views about three NOS themes before and after completing the course. Qualitative data were collected from eight of the teachers who were observed teaching during their field experience after completing the course. The teachers’ post-course mean NOS scores were statistically significantly higher than their pre-course scores (t (65) =-10.08, p<.001; Cohen’s d = 1.4). Despite the favourable NOS knowledge among the science teachers, low levels of NOS portrayal were observed in their instructional practices. These findings point to some success in explicitly addressing NOS in science education content courses. However, they raise questions about the transferability of teachers’ NOS knowledge into their classrooms. The findings have implications for teacher-preparation programmes regarding durability of NOS knowledge.

Australian Journal of Teacher Education
Many countries all over the world have recently integrated nature of science (NOS) concepts into their science education standards. Providing professional support to teachers about NOS concepts is crucially important for successful implementation of the standards. For this purpose, a summer science camp was offered to elementary and science teachers. The main objective of this research study was to investigate the progress in specific NOS concepts made by the participant teachers. The responses of the teachers regarding the NOS concepts were obtained through VNOS-C questionnaire and scored using a rubric developed by McDonald (2008). The scored teacher responses were analyzed …

The aim of this study was to investigate the effect of an activity-based explicit nature of science (NOS) instruction undertaken in the context of a “Science, Technology and Society” course on the prospective science teachers’ (PSTs’) understandings of NOS. In this course, social science based inquiry activities were used to as a context to lead reflection and explicit discussions and project based learning approach (PBL) was used to model an active student centred NOS teaching and learning. Participants were 36 senior PSTs. An adopted form of VNOS questionnaire along with semi-structured interviews was used to assess participants’ conceptions before and …
