In order to bring change in science teaching and learning processes, it is crucial in the science teacher education literature to understand and challenge the teachers’ knowledge about Nature of Science (NOS). This quantitative research study provides insight into teachers’ perception about NOS by using “Views on Science-Technology-Society” (VOSTS) questionnaire. Hence, this book helps readers understand the history and importance of NOS, provides a view of the questionnaire administration process and presents the analysis of the questionnaire. Finally, looking at the findings, few recommendations are also made for future studies. This book is valuable particularly for teacher educators and researchers.
