In 2002, the Swedish National Food Agency and researchers from Stockholm University made an announcement regarding the presence of acrylamide in carbohydrate-rich foods that are exposed to high temperatures, with cereals, potatoes, and coffee possibly being the most significant sources of ingestion. Although limited data are available on assessing…

Evolutionary medicine is a growing area of research and practice; however, it is not widely discussed in introductory biology courses. Because of the interest in human biology, using evolutionary medicine is a great way to hold students' interest, placing topics in context, making the subject of evolution relevant. Too often students lose interest…

"Multimodal Signs of Learning" proposes a methodology to uncover evidence of learning in students' multimodal compositions. Informed by social semiotic theory, the book tracks representation of subject content from physical and embodied teaching resources to students' handmade artefacts and physical presentations. Using materials from…

The purpose of this qualitative study was to investigate preservice elementary teachers' science teacher identity development during their participation in the field-based science methods course and a year after. Grounded within the Feiman-Nemser's thematic framework of learning to teach, this study utilized a case study approach aimed to examine…

Have you ever taught "head on the table" physics students and wondered how to increase engagement? If so, I have two stories for you! Davon and Cynthia--both case study students--struggled with traditional physics but showed great promise with developing personalized physics problems.

"Cases are stories with a message. They are not simply narratives for entertainment. They are stories to educate" (Herreid, 1997, p. 92). By this definition, a case study is two things: a story and a strategy to drive learning. Although the story typically comes from a narrative purposefully written for the classroom, such as the case…

Digital learning environments such as virtual laboratories have been proposed to augment or even replace conventional forms of teaching in recent years. While there is some evidence on comparable learning outcomes between real and virtual labs, empirical evidence on the effectiveness of virtual labs as compared to conventional face-to-face…

One main obstacle for instructors in inviting students to design knowledge construction is the tension between prioritizing students' ideas and maintaining the scientific validity of the activity. In this study, as a way of supporting students in shaping their own knowledge construction, the establishment of an audience for knowledge was enacted…

Studies in the field of science education have discussed using historical approaches. Although previous studies have shown the potential advantages to addressing national sciences in the classroom in countries underrepresented in the history of science, there are still few initiatives in this direction. Thus, this paper aims to explore a…

Sensemaking has been advocated as a core practice of science education to support students in constructing their own understanding through a prolonged trajectory. However, the field lacks a discussion of teaching strategies that can better support students as they develop in the trajectory of sensemaking, which includes four phases: initial…

This article introduces and contextualizes the content of this theme issue of "The American Biology Teacher" (ABT), which focuses on integrating elements of the history of science (HOS) in biology instruction. Such orientations can enhance students' understanding of core biological concepts and the process of scientific discovery by…

Diffraction is an important phenomenon in physics. This paper describes using a scanning electron microscope (SEM) to produce cross-sectional images of iridescent seashells. When seashell cross-sections are viewed in a SEM, regular structure is seen. Seashells are a good example of a biocomposite material and good natural objects for introducing…

This multiple case study focused on the implementation of a computer-aided design (CAD) simulation to help students engage in engineering design to learn science concepts. Our findings describe three case studies that adopted the same learning design and adapted it to three different populations, settings, and classroom contexts: at the…

This paper investigates the interactions between context and professional development of physics instructors in a case study of two physics faculty. A phenomenological-case study approach was used to analyze two physics faculty at different institutions over a year and a half using three semistructured interviews each. The data enabled the…

Achieving deeper and permanent learning has always been the focus of teaching force. This purpose is independent of the teaching level or subject matter. Pre-service teachers' lack of interest and inability to connect learning levels are partly cited for their inability to develop this deeper and permanent learning of science concepts. In this…
