The present study aimed to evaluate the use of metaphors by preservice science teachers on the subject of genetically modified organisms (GMOs). In the study, a phenomenology method was employed in the scope of a qualitative research model. The study group was composed of 189 preservice teachers who were employed in various science fields (e.g.,…

The plant taxonomy textbooks that are generally used in colleges need to be complemented with a DNA-based molecular review. In general, plant taxonomy textbooks devote more space to morphology than to molecular-level characteristics. The research reported here used the results of DNA-based research to develop a molecular plant taxonomy textbook.…

The purpose of this study is to determine the alternative conceptions of elementary school pre-service science teachers regarding DNA and DNA technologies. The questions asked in the study related to subjects including the structure and role of DNA molecule, structure of genes, some genetic technologies, Genetically Modified Organism (GMO) plants,…

This paper reports an interview case study with two physics doctoral students designed to explore their conceptions about the theory of evolution. Analysis of interview transcripts reveals that both students mistakenly constructed a "theory of evolution by environmentally driven adaptation" instead of the commonly accepted "theory…
