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…

Integrating the nature of science (NOS) into textbooks is one of the challenges in science curricula. This case study assessed the issue based on a sample of high school biology textbooks in Mainland China. We quantitatively compared changes in the extent, quality, and distribution of NOS representations between 2004 and 2019 editions. Three main…

Spatial skills are embedded in all aspects of the geosciences. The teaching and learning of spatial skills has been a challenging, but vital, endeavor. To support student learning of spatial skills in undergraduate courses, we designed scaffolds for spatially dependent content in a mid-level geoscience course using playdough to allow students to…

In this article, we assume that discursive language aspects of science education are highly intertwined with students' knowledge-building and meaning-making in science. In an empirical case study, we investigate secondary students' (ages 15 to 16) discursive language use during group interactions. The focus is on how students define and explain…

Problem-based learning encourages students to deepen their understanding of a concept by working through a real-world example of course content. Case studies represent a form of problem-based learning that engages students in realistic scenarios to achieve a deeper understanding of concepts. Case studies have been shown to facilitate the learning…

The onset of the Next-Generation Science Standards [NGSS] has created a need for elementary teachers to develop purposeful, multi-dimensional formative assessments (FAs). In order to promote this process, we utilized teacher learning communities (TLCs) and practice-based professional development focused on key aspects of the reform while…

Despite the importance of scientific argumentation, it rarely occurs in science classrooms. Researchers have designed argumentation interventions to bridge this gap, but those efforts have limited impacts on transforming existing classroom practices. Argumentation is a linguistically social interaction. It is necessary to go beyond understanding…

Research from the fields of science representation, genre pedagogy and disciplinary literacy for adolescents indicates that achievement for students, including those from linguistically diverse backgrounds, will improve if they engage with the meaning-making conventions of disciplinary texts, but there is no current agreement on the nature of…

Nature of science (NOS) is considered an important aspect of scientific literacy. Despite efforts in guiding school students to develop more adequate NOS views, little is known about the long-term retention of students' post-intervention views. Retention of adequate NOS views is needed for functioning as scientifically literate citizens. Moreover,…

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…

Diversity, equity, and inclusion (DEI) practices are a hallmark of high-impact pedagogy. Such practices are common in discussions regarding the retention of all students in STEM, but especially those with identities such as Black, Indigenous, persons of color, female, and LGBTQIA+. However, the extent to which DEI-framed content improves alignment…

This study examines the development of secondary preservice science teachers' (PSTs') sociopolitical understandings in the context of a yearlong, masters-level, justice-oriented teacher education program. It articulates a theoretical perspective regarding teachers' conceptions of the work-of-teaching in terms of pedagogical and disciplinary…

The purpose of this study was to understand how biology teachers experienced and learned from professional development (PD) in which the 5R Instructional Model was used as a framework for planning inclusive lesson for emerging multilingual learners (EML). The PD integrated biology content with the scientific practices of using mathematical…

Student achievement is rooted in a teacher's ability to identify and assess student understanding of material. This is particularly challenging in classroom settings, which are dynamic and full of distractions, especially in science classrooms where discussion and inquiry are paramount. In mathematics education, the concept of "professional…

The term "boundary-work" is used to refer to the constant effort to draw and re-draw the boundary of science; it has long been portrayed as constructed by the stakeholders of science to demarcate science from non-science to establish the authority of science. Twenty-nine semi-structured interviews were carried out with students from one…
