Evolution is foundational to understanding biology, yet learners at all stages have incomplete and incorrect ideas that persist beyond graduation. Contextual features of prompts (e.g., taxon of organism, acquisition vs. loss of traits, etc.) have been shown to influence both the learning process and the ideas students express in explanations of…

This study aims to analyze a moderated mediation model using the Job Demands-Resources model in order to test the mediation role of emotional exhaustion in the relationship between emotional demands in schools and teacher presenteeism, and moderator role of trust in principal in this mediation process. Using data from a sample of 796 teachers…

Biology teachers hope to teach their students more than, say, the steps of aerobic respiration. They want to help students see the living world around them in new and deeper ways. Unfortunately, the living world students encounter every day--in schoolyards and forest preserves, pets and potted plants, soil fungus and sourdough bread--is too rarely…

Organismal biology (OrgBio) comprises the diversity, structures, and functions of all organisms from bacteria to humans. Arguably, OrgBio is often the most poorly taught and least conceptually rigorous section of the introductory biology sequence offered at most U.S. institutions of higher education. This article reports on the successful…

To transition introductory college science courses from large, passive lectures to more student-centered learning environments, additional instructional support is needed. Peer learning assistants (PLAs) can support that transformation by engaging students in interactive discourse and collaborative learning during class activities. PLAs are…

There is emerging recognition that mechanistic reasoning about scientific phenomena as well as developing an interdisciplinary understanding of science are valuable for student success. Our team of chemistry, biology, and teacher education researchers strives to support students in their interdisciplinary learning and engage them in causal…

Through the lens of Maslach's (1995) Multi-Dimensional Theory of Burnout, and Stamm's (2012) Quality of Life Survey (ProQOL), the study examined educators scores regarding various logistics. The purpose of this quantitative, causal comparative study was to test the multi-dimensional theory of burnout by comparing various demographics of school…

A previously healthy university student presents to Health Services with sudden onset of pain, fatigue, bruising, and a rapidly progressive anemia. There was not any previous significant health history. The case discussion will emphasize the critical overlap of physical and mental health assessments in identifying the cause and cure of a…

Quantitative analysis in analytical chemistry is divided into semi-,relative, and absolute analysis. An example of each analysis is pH test paper, internal standard, and standard addition, respectively. However, their definition and differences have not yet been explained to students sufficiently in classes as well as textbooks. Polymerase chain…

Gel electrophoresis (GE) is the most preferred and adapted technique for the separation and identification of biological molecules like proteins/peptides and nucleic acids from diverse types of organisms. All over the world, researchers, educators, and students aspiring to work in biochemistry and molecular biology disciplines use the…

This dissertation features a set of three sub-studies situated within a larger Critical Participatory Ethnography investigating how participatory science unfolds between youth and scientists to address issues of marine plastic pollution. Collectively the papers provide insights into how to navigate the slippery, but necessary, terrain of teaching…

This paper's focus is on the "middle" of partnerships for equity in science education. Middle is used in a temporal sense, meaning the time after the general purposes and terms of working together have been set and before outcomes have been achieved. The middle of the partnership also represents people interacting, bounded around the…

Biomimicry has been proposed as an important tool to reach key skills for the new century. It has taken its place as an essential resource for critical and creative thinking in design disciplines. However, as emphasized in many studies, bio-informed research requires interdisciplinary collaboration and systematic knowledge transfer. This article…

Objective: We sought to identify the general health of college students. Participants: A total of 4402 university freshmen and sophomores were recruited to report their general health through an online questionnaire. Methods: Responses from the DePaul Symptom Questionnaire were analyzed. We then conducted latent class analyses to evaluate 54…

An essential skill for STEM undergraduates is the ability to understand the world by manipulating, visualizing, and analyzing data to make or evaluate claims. Current online debate, without peer-reviewed literature, explores which of two common R syntax environments (base R or tidyverse) is best for teaching novice R users. In an in-person…
