Taylor, Robin T.; Bishop, Pamela R.; Lenhart, Suzanne; Gross, Louis J.; Sturner, Kelly – CBE - Life Sciences Education, 2020
We describe the development and initial validity assessment of the 20-item BioCalculus Assessment (BCA), with the objective of comparing undergraduate life science students' understanding of calculus concepts in different courses with alternative emphases (with and without focus on biological applications). The development process of the BCA…

Tripp, Brie; Voronoff, Sophia A.; Shortlidge, Erin E. – CBE - Life Sciences Education, 2020
A desired outcome of education reform efforts is for undergraduates to effectively integrate knowledge across disciplines in order to evaluate and address real-world issues. Yet there are few assessments designed to measure if and how students think interdisciplinarily. Here, a sample of science faculty were surveyed to understand how they…

Esparza, David; Wagler, Amy E.; Olimpo, Jeffrey T. – CBE - Life Sciences Education, 2020
Course-based undergraduate research experiences (CUREs) serve to increase student access to authentic scientific opportunities. Current evidence within the literature indicates that engagement in CUREs promotes students' science identity development, science self-efficacy, motivation, and ability to "think like a scientist." Despite the…

Branchaw, Janet L.; Butz, Amanda R.; Smith, Amber R. – CBE - Life Sciences Education, 2020
The second edition of "Entering Research" (ER) is a collection of customizable active-learning activities, resources, and assessment and evaluation tools for use in undergraduate and graduate research training programs and courses. Results from two design and development research studies examining the effectiveness of the second edition…

Leupen, Sarah M.; Kephart, Kerrie L.; Hodges, Linda C. – CBE - Life Sciences Education, 2020
Group activities as part of active-learning pedagogies are thought to be effective in promoting student learning in part because of the quality of discussion they engender in student teams. Not much is known, however, about which instructional factors are most important in achieving productive conversation or how these factors may differ among…

Bauer, Angela C.; Coffield, Vernon M.; Crater, Dinene; Lyda, Todd; Segarra, Verónica A.; Suh, Kevin; Vigueira, Cynthia C.; Vigueira, Patrick A. – CBE - Life Sciences Education, 2020
Recent studies demonstrate that significant learning gains can be achieved when instructors take intentional steps to address the affective components of learning. While such efforts enhance the outcomes of all students, they are particularly beneficial for students from underrepresented groups and can reduce performance gaps. In the present…

Limeri, Lisa B.; Choe, Jun; Harper, Hannah G.; Martin, Hannah R.; Benton, Annaleigh; Dolan, Erin L. – CBE - Life Sciences Education, 2020
Whether students view intelligence as a fixed or malleable trait (i.e., their "mindset") has significant implications for their responses to failure and academic outcomes. Despite a long history of research on mindset and its growing popularity, recent meta-analyses suggest that mindset does a poor job of predicting academic outcomes for…

Chen, Chen; Sonnert, Gerhard; Sadler, Philip M.; Sunbury, Susan – CBE - Life Sciences Education, 2020
One of the foundational assumptions in education is that greater teacher knowledge contributes to greater gains in student knowledge, but empirical evidence in support of this assumption is scarce. Using a U.S. sample of 79 biology teachers and their 2749 high school students, we investigate whether teachers' subject matter knowledge (SMK) and…

Göransson, Andreas; Orraryd, Daniel; Fiedler, Daniela; Tibell, Lena A. E. – CBE - Life Sciences Education, 2020
Evolutionary theory explains a wide range of biological phenomena. Proper understanding of evolutionary mechanisms such as natural selection is therefore an essential goal for biology education. Unfortunately, natural selection has time and again proven difficult to teach and learn, and students' resulting understanding is often characterized by…

Lira, Matthew; Gardner, Stephanie M. – CBE - Life Sciences Education, 2020
When a student explains a biological phenomenon, does the answer reflect only the "product of retrieving knowledge" or does it also reflect a "dynamic process of constructing knowledge?" To gain insight into students' dynamic knowledge, we leveraged three analytic frameworks--structures--behaviors--functions (SBF), mental…

Wilson, Kristy J.; Long, Tammy M.; Momsen, Jennifer L.; Speth, Elena Bray – CBE - Life Sciences Education, 2020
As an instructional tool, models can transform the student experience from the static to the dynamic, the flat to the 3D, and the siloed to the integrated. Few practical resources exist to help instructors transition toward model-based classroom practices. The "Modeling in the Classroom" evidence-based teaching guide provides instructors…

Szteinberg, Gabriela; Repice, Michelle D.; Hendrick, Claudia; Meyerink, Stephen; Frey, Regina F. – CBE - Life Sciences Education, 2020
As research has shown, collaborative peer learning is effective for improving student learning. Peer-led team learning (PLTL) is one well-known collaborative-group approach in which groups are facilitated by trained undergraduate peer leaders. This paper contributes to the literature on peer-leader training by examining how peer leaders for a…

Sorte, Cascade J. B.; Aguilar-Roca, Nancy M.; Henry, Amy K.; Pratt, Jessica D. – CBE - Life Sciences Education, 2020
Science instructors are increasingly incorporating teaching techniques that help students develop core competencies such as critical-thinking and communication skills. These core competencies are pillars of career readiness that prepare undergraduate students to successfully transition to continuing education or the workplace, whatever the field.…

Zambrano, Jeanette; Lee, Garam Ann; Leal, Christina C.; Thoman, Dustin B. – CBE - Life Sciences Education, 2020
The prevalent stereotype that scientific fields do not afford opportunities to fulfill goals of helping others deters student interest and participation in science. We investigated whether introductory college science textbooks that highlight the prosocial utility value of science can be used to change beliefs about the affordances of scientific…

Peugh, James; Feldon, David F. – CBE - Life Sciences Education, 2020
Structural equation modeling is an ideal data analytical tool for testing complex relationships among many analytical variables. It can simultaneously test multiple mediating and moderating relationships, estimate latent variables on the basis of related measures, and address practical issues such as nonnormality and missing data. To test the…
