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.,…

Students have difficulties understanding the crossing-over field concept in genetic courses because within the concept of crossing-over there are facts and problems that are difficult to solve as well as the absence of valid, practical, and effective student worksheets. So that the learning process is complete, activities and student learning…

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.…

Pedagogical Content Knowledge (PCK) refers to certain knowledge of teacher in a particular topic, considered as an act of teaching to deal with students in a particular way. Since PCK allows a science teacher to provide quality teaching, this qualitative multiple case study aims to explore the nature of science teachers' PCK on the topic…

This paper investigated the use of term recall and recognition tools for learning terminology and concepts in a senior biology classroom. The paper responded to a set of research questions from a teacher researcher perspective, making use of data collected from the teacher researcher's classrooms over several years, based on the implementation of…

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 study aims to investigate the effects of concept maps, together with conceptual change texts, given to 11th grade students' on the subject of molecules carrying genetical information. The semistructured individual interviews were conducted with 5 upper class students to find misconceptions related to the subject. A success test was developed…

The purpose of this study was to investigate the effects of tutorial and edutainment software programs related to "genetic concepts" topic on student achievements, misconceptions and attitudes. An experimental research design including the genetic concepts achievement test (GAT), the genetic concept test (GCT) and biology attitude scale…

Scientific literacy is the ultimate goal in science education world-wide; especially in this modern society of science and technology. How to help individuals to make good judgments and promote their skills of argumentation becomes an important issue.
