To fully appreciate genetics, one must understand the link between genotype (DNA sequence) and phenotype (observable characteristics). Advances in high-throughput genomic sequencing technologies and applications, so-called "-omics," have made genetic sequencing readily available across fields in biology from applications in…

A discrete model of invasion by subversive alien bodysnatchers is constructed and analysed numerically as a proposed undergraduate project. Several extensions of the model are demonstrated, including a spatial system of ten planets arranged on a one-dimensional lattice, and we discuss some of the practical considerations that arise when…

This paper examines three in-service science teachers' use of argument-driven inquiry (ADI) instructional model in an urban school district. We explore the basis for teachers' adaptation of the ADI model. The data were collected through teacher interviews and classroom observations from three science teachers. Data analysis indicated that three…

Science as an enterprise has been and continues to be exclusionary, perpetuating inequities among whose voice is heard as well as what/whose knowledge is recognized as valid. Women, people of color, and persons with disabilities are still vastly outnumbered in science and engineering by their White, male counterparts. These types of imbalances…

The Community of Practice framework has been used theoretically and empirically to describe the diverse ways people learn from one another through social interaction in a variety of specific contexts. To date, most research of this genre has favored investigating the community and domain constructs of the theory over the authentic practice…

The future viability of the geosciences is challenged, since as a community we continue to lack demographic diversity representative of the wider population. Fundamentally, dominant cultural, historical, and socioeconomic factors contribute to the lack of diversity and those factors typically change slowly over generations. Proposals for more…

This paper describes an undergraduate biochemistry laboratory module consisting of a set of experiments designed around a purification scheme for bovine serum albumin (BSA). Students purify BSA from cow plasma by a combination of salt and acetone precipitation, equilibrium dialysis, ion exchange, and size exclusion chromatography. Students use the…

Many studies in science education research have found metacognition to be beneficial for undergraduate STEM students. Students do not necessarily know how to employ their metacognition without some training or prompting, and undergraduate chemistry instructors do not always have the capacity to instruct their students on metacognition. Thus, it…

Philosophy is concerned with fundamental questions about knowledge, truth, reality, experience, justice and what is right and wrong. In this article, the authors discuss how philosophy and science can be taught together in the primary classroom.

A high self-efficacy in teaching is sometimes used as a kind of litmus test of science teaching practices. However, the connection between self-efficacy and teaching effectiveness is not well established. Therefore, this study sought to investigate the connections between self-efficacy and enacted science teaching of preservice elementary…

Curiosity is the inner drive for learning or 'hunger for learning' which is among the twenty-first-century learning competencies. Students in their earliest stage ought to exhibit curiosity to stir up knowledge acquisition and exploration, yet the development of curiosity in the context of education is considered to be unusual. This research…

Designing a science activity for middle school children is a challenging task, especially if it aims to be interdisciplinary. One may ask if it is possible to craft a positive learning experience from different areas such as history of science, chemistry, or ethics. In this paper, we argue it can be achieved if we use the right tools to engage a…

Peer learning has become a central feature in many postsecondary classrooms. Many peer learning activities feature near-peer instructors who had previously completed the course and who later serve as peer leaders. There are relatively few examples of activities in which students in a course act as true peer instructors for their classmates. One…

Understanding the relationship between protein structure and function can be challenging for students. Molecular visualization software aids students in this problem by allowing manipulation of structures from new and deeper perspectives. In this communication, an activity using iMolview Lite, structure visualization software for portable devices,…

Polarization of light is one of the topics in the Croatian high school physics curriculum. It is taught in the final year of high school education. Twenty-seven Croatian high-school students (aged 18-19 years) were interviewed after regular instruction about their understanding of polarization of light and the model of light itself. This paper…
