The study aimed to investigate the effect of project supervision training offered to Biology teachers on their viewpoints about the nature of scientific researches. In the study, action research design, one of the quantitative research methods, was adopted. The participants of the study were composed of 39 Biology teachers who had attended a training on project supervision. The data were collected using Assessment of Learners' Views about Scientific Iquiry (VOSI) developed by Schwarts, Lederman and Lederman (2008); and a semi-structured interview form developed by the researchers. The data were analyzed via coding and content analysis methods. The results revealed that the the project supervision training provided them with the development on five dimensions, such as scientific research is directed by questions, using different methods in scientific research, research has many purposes, justification of scientific knowledge, and differences between scientific data and evidence.
