We explored adaptations to an elementary science methods course to determine how varied contexts could improve elementary preservice teachers' conceptions of NOS as well as their ideas for teaching NOS to elementary students. The contexts were (a) NOS Theme in which the course focused on the teaching of science through the consistent teaching…

This study explored the effects that the incorporation of nature of science (NoS) activities in the primary science classroom had on children's perceptions and understanding of science. We compared children's ideas in four classes by inviting them to talk, draw and write about what science meant to them: two of the classes were taught by "NoS"…

The purpose of this study was to investigate changes in preservice teachers' understanding of the nature of science (NOS) as a result of four activity-based interventions that represent three instructional approaches used in a middle grades science methods course. Ten participants' understanding of NOS and their perceptions about the…

This study has identified the effectiveness of using portfolios for the prospective teachers as a tool of an explicit, reflective, and instructional approach in science education. Early childhood science method courses in a college for unskilled early childhood teachers influence their theory and practice toward science teaching. It describes…

School science systems tend to emphasize teaching and learning about achievements of science (such as laws and theories) at the expense of providing students with opportunities to develop realistic conceptions about science and science inquiry and expertise they could use to conduct their own science inquiry projects. Among reasons for such an…

This investigation assessed the impact of situating explicit nature of science (NOS) instruction within the issues surrounding global climate change and global warming (GCC/GW). Participants in the study were 15 preservice elementary teachers enrolled in a science methods course. The instructional intervention included explicit NOS instruction…

This inquiry uses teacher-candidate critiques of science lessons as a means of evaluating the effectiveness of an instructor's pedagogical approach to promote teacher candidate understanding of the nature of science (NOS) in a science methods course. Three cohorts of teacher candidates enrolled in a middle-years teacher education program were…

The nature of science (NOS) has a prominent role among the national science education content standards at all grade levels, K-12. Results from a national survey of collegiate science educators indicate the perception that the greatest contributors to preservice teachers' understanding of the nature of science were science methods courses,…
