Genetics literacy is becoming increasingly important as advancements in our application of genetic technologies such as stem cell research, cloning, and genetic screening become more prevalent. Very few studies examine how genetics literacy is applied when reasoning about authentic genetic dilemmas. However, there is evidence that situational…

Scientific teaching requires scientifically constructed, field-tested instruments to accurately evaluate student thinking and gauge teacher effectiveness. We have developed a 23-question, multiple select--format assessment of student understanding of the essential concepts of the central dogma of molecular biology that is appropriate for all…

In this study, we investigate museum visitor learning and engagement at an interactive visualization of an evolutionary tree of life consisting of over 70,000 species. The study was conducted at two natural history museums where visitors collaboratively explored the tree of life using direct touch gestures on a multi-touch tabletop display. In the…

Darwinian evolution is difficult to understand because of conceptual barriers stemming from intuitive ideas. This study examined understanding of evolution in 52 students (M = 14.48 years, SD = 0.89) before and after a guided field trip to a natural history museum and in a comparison group of 18 students (M = 14.17 years, SD = 0.79) who did not…

The conflicts between nature and nurture are brought to the fore and challenges socio-scientific decision-making in science education. The multitude of meanings of these concepts and their roles in societal discourses can impede students' development of understanding for different perspectives, e.g. on gene technology. This study problematizes…

The purpose of the study is to explore Turkish preservice science teachers' informal reasoning regarding socioscientific issues and the factors influencing their informal reasoning. The researchers engaged 39 preservice science teachers in informal reasoning interview and moral decision-making interview protocols. Of the seven socioscientific…

Despite consistent evidence that serotonin functioning affects stress reactivity and vulnerability to aggression, research on serotonin gene-stress interactions (G x E) in the development of aggression remains limited. The present study investigated variation in the promoter region of the serotonin transporter gene (5-HTTLPR) as a moderator of the…

The perception of science as boring is a major issue for teachers at all instructional levels. Tertiary classes especially suffer from a reputation for being dry, instructor-centered, and irrelevant to the lives of students. However, previous research has shown that science can be interesting to students if it is presented in such a manner as to…

The present research was conducted with the aim of examining the foreign language learning needs of graduate and postgraduate students of Genetics in Iran in order to help students to meet the growing present and emerging future language demands. The study was designed on a qualitative-quantitative survey basis using interviews and questionnaires…

Within the framework of social cognitive theory, the influence of self-efficacy beliefs and metacognitive prompting on genetics problem solving ability among high school students in Kenya was examined through a mixed methods research design. A quasi-experimental study, supplemented by focus group interviews, was conducted to investigate both the…

DNA and DNA related technologies have become a part of daily life in the 21st century. In today's world, it is a necessity for science teachers to keep up with current changes in sciences and be able to teach the content in their classrooms. Such needs in consideration, professional development programs aim to help teachers during the transition…

Objective: The current study tests electroencephalogram (EEG) measures as a potential endophenotype for attention deficit/hyperactivity disorder (ADHD) by examining sibling and parent-offspring similarity, familial clustering with the disorder, and association with the dopamine receptor D4 (DRD4) candidate gene. Method: The sample consists of 531…

Studies from different theoretical traditions investigating children's inheritance and genetics concepts have adopted a cross-sectional method. This paper is the first to examine both cross-sectional and longitudinal changes in children's basic genetic concepts. It forms part of a larger investigation into the development of intuitive inheritance…

Of concern is an international trend of students' increasing reluctance to choose science courses in both their final years of secondary school and tertiary levels of education. Research into the phenomenon indicates an influencing factor to be the "uninteresting curriculum" (OECD, 2006) of school science. This article presents an…

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…
