The integration of scientific modeling into science teaching is key to the development of students' understanding of complex scientific phenomena, such as genetics. With this in mind, we conducted an introductory hands-on module during an outreach gene technology laboratory on the structure of DNA. Our module examined the influence of two model…

This study aims to categorize the scenarios designed on socio-scientific issues (SSIs) by prospective teachers who participated in an SSI-based instructional practice and to analyze these scenarios in terms of representing the nature of science (NOS) components. Sample of the study comprised SSI scenarios written by 30 third-year prospective…

Truncating variants of the "MAGEL2" gene, one of the protein-coding genes within the Prader-Willi syndrome (PWS) critical region on chromosome 15q11, cause Schaaf-Yang syndrome (SYS)--a neurodevelopmental disorder that shares several clinical features with PWS. The current study sought to characterize the neurobehavioral phenotype of SYS…

Conrad Hal Waddington's epigenetic landscape is now a central paradigm in evolutionary developmental biology. This article proposes that it should be adopted into middle-years (ages 11-16) biology curricula as a way of visualising the interactions of the genome with the environment. The epigenetic landscape is explained, with some biographical…

The rapidly growing field of epigenetics is now beginning to reveal how our genes are affected by environmental factors such as nutrition, exercise and stress. As it has such profound effects on our everyday lives, this article argues for the inclusion of epigenetics in the compulsory school science curriculum, and explores trainee science…

The research presented in this essay is grounded in Social Domain Theory. Research provides substantial evidence that children's social development is characterized by the formation of distinctly different systems of thought, including those in the moral, social-conventional, and personal domains. A main focus here is on morality, defined as…

William's Syndrome (WS) is a rare neurodevelopmental disorder caused by a genetic abnormality, affecting about 1 in 10,000 people worldwide. While there are some behavioral similarities between WS and other high incidence disabilities, such as autism, several unique physical, cognitive, and behavioral characteristics are expressed in individuals…

Scientific literature about neuromyths has proliferated in the last few years. However, there is a gap of knowledge around neuroedumyths. While neuromyths are based on hoaxes about the brain, neuroedumyths use neuroscientific concepts but state consequences for education that are false. This article presents, for the first time, research about…

This study aimed at designing instructional material named Biotechnology Instruction Module (BIM) which is enriched with active learning methods to enhance the 8th grade students' learning of the topic. The development of the teaching materials proceeded within the stages of the ADDIE instructional design model. The final form of the instructional…

Sickle Cell Disease (SCD) is an inherited blood disorder affecting approximately 1 in every 365 African American births. Students with SCD are likely to experience ongoing complications that will interfere with their attendance, functioning at school, and overall daily functioning throughout their lives. This article provides education about SCD…

The last class session of the academic term represents an excellent opportunity to solicit meaningful feedback from students who have just completed the course. To capitalize on the students' first-hand knowledge of their own experiences with our course and maximize the impact of the last class for our Canadian graduate-level genetics course, we…

What contributes to science skepticism? Virtually every U.S. high-school student is required to study biology, at minimum, to earn a diploma. But the exact content of the course varies from state to state. This article investigates the role of state standards for high-school science content in shaping knowledge and attitudes about…

Undergraduate genetics courses have historically focused on simple genetic models, rather than taking a more multifactorial approach where students explore how traits are influenced by a combination of genes, the environment, and gene-by-environment interactions. While a focus on simple genetic models can provide straightforward examples to…

Individuals of the same species display remarkable variation in behavior, even in identical contexts. Increasing complexity in behavioral phenotypes brings with it an increase in individual variation in the manifestation of those phenotypes, and human behavior undoubtedly stands at the pinnacle of complexity. In this article, we discuss current…

This teaching brief describes an engaging, in-class exercise that introduces genetic algorithms as well as advanced Excel functions and capabilities by modeling the familiar Sudoku puzzle. Student groups are first asked to manually solve a given puzzle and then translate that solution methodology to a spreadsheet model. This exercise can be used…
