How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

Article
In recent years, there has been a strong push to transform STEM education at K‐12 and collegiate levels to help students learn to think like scientists. One aspect of this transformation involves redesigning instruction and curricula around fundamental scientific ideas that serve as conceptual scaffolds students can use to build cohesive knowledge...

We systematically compared two coding approaches to generate training datasets for machine learning (ML): (i) a holistic approach based on learning progression levels and (ii) a dichotomous, analytic approach of multiple concepts in student reasoning, deconstructed from holistic rubrics. We evaluated four constructed response assessment items for u...
Article
Avian incubation investment represents a trade‐off between the energetic demands of the parent and the thermal needs of the embryo. Parental energy balance and investment in somatic maintenance relative to incubation investment can be indexed by the rate of feather growth. Feather growth rates, or ptilochronology, of adult Leach’s Storm‐Petrels Oce...

Constructed responses can be used to assess the complexity of student thinking and can be evaluated using rubrics. The two most typical rubric types used are holistic and analytic. Holistic rubrics may be difficult to use with expert-level reasoning that has additive or overlapping language. In an attempt to unpack complexity in holistic rubrics at...

Flux is a core concept and principle in undergraduate physiology that describes passive flow of substances and heat down gradients. Student thinking about flux can be characterized using a learning progression (LP) framework. LPs are frameworks which outline cognitive paths of student learning in a domain and can provide reference points of student...
Poster
Full-text available
This poster shows our work developing a learning progression that describes how students' ideas about mass balance/pools and flux/accumulation in physiological systems gains sophistication.
Article
Full-text available
The basis for understanding neurophysiology is understanding ion movement across cell membranes. Students in introductory courses recognize ion concentration gradients as a driving force for ion movement but struggle to simultaneously account for electrical charge gradients. We developed a 17-multiple-choice item assessment of students' understandi...

Poster
Full-text available
Learning progressions (LPs) are frameworks which outline cognitive paths of students and can provide reference points for student progress. LPs are built using evidence about student reasoning collected by a complex and iterative routine of LP development, assessment item and rubric development, data collection, human coding and re-alignment of LPs...
Article
Full-text available
All species should invest in systems that enhance longevity; however, a fundamental adult life-history trade-off exists between the metabolic resources allocated to maintenance and those allocated to reproduction. Long-lived species will invest more in reproduction than in somatic maintenance as they age. We investigated this trade-off by analyzing...
Article
Full-text available
For all species, finite metabolic resources must be allocated toward three competing systems: maintenance, reproduction, and growth. Telomeres, the nucleoprotein tips of chromosomes, which shorten with age in most species, are correlated with increased survival. Chick growth is energetically costly and is associated with telomere shortening in most...

Background: In dimorphic seabirds, the larger sex tends to provision more than the smaller sex. In contrast, monogamy and biparental care are often associated with equal effort between the sexes. However, the few studies that have tested sex-specific effort in monomorphic seabirds have primarily examined the details of foraging at sea. Hypotheses:...
Article
The nocturnal activity of burrow-nesting seabirds, such as storm-petrels and shearwaters, makes it difficult to study their incubation behavior. In particular, little is known about possible differences in the incubation behavior of adults at successful and unsuccessful nests. We combined the use of passive integrated transponder (PIT) technology a...
