The well-established finding that substantial confusion and misconceptions about evolution natural selection persist after college instruction suggests these courses neither foster accurate mental models of evolution's mechanisms nor instill an appreciation centrality to understanding the living world. Our essay explores roles introductory biology textbooks may play in reinforcing undergraduates' pre-existing, faulty place biological sciences. content analyses three best-selling for majors...
Undergraduate research experiences confer benefits on students bound for science, technology, engineering, and mathematics (STEM) careers, but the low number of professionals available to serve as mentors often limits access research. Within context our summer program (BRAIN), we tested hypothesis that a team-based collaborative learning model (CLM) produces student outcomes at least positive traditional apprenticeship (AM). Through stratified, random assignment conditions, CLM were...
Pacific salmon (genus Oncorhynchus) exhibit an interesting and uncommon life-history pattern that combines semelparity, anadromy, navigation (homing). During smoltification, young imprint on the chemical composition of their natal stream water (the home-stream olfactory bouquet or "HSOB"); they then migrate to ocean where spend a few years feeding prior migrating back freshwater spawn. Upstream migration is guided by amazing ability discriminate between compositions different waters thus...
Undergraduate students may be attracted to science and retained in by engaging laboratory research. Experience as an apprentice a scientist's can effective this regard, but the pool of willing scientists is sometimes limited sustained contact between faculty minimal. We report outcomes from two different models summer neuroscience research program: Apprenticeship Model (AM) which individual joined established laboratories, Collaborative Learning (CLM) teams worked through guided curriculum...
Abstract Sex differences in the zebra finch ( Taeniopygia guttata ) brain are robust and include morphology (song control nuclei males significantly larger) behavior (only sing courtship songs). In finches, hormonal manipulations during development fail to reverse sex song size suggest that classical model of sexual differentiation is incomplete for birds. Coactivators act initiate transcriptional activity steroid receptors, may help explain why alone not sufficient demasculinize male brain....
A hummingbird can hear high-pitched sounds that most birds cannot perceive.
Parental stress is an important risk factor for child maltreatment (CM) perpetration. Evidence-based, parent-training programs can decrease CM perpetration and reduce self-reported parental stress; however, little known about how such impact physiological correlates. In this quasi-experimental pilot study, maternal biobehavioral responses were measured in response to SafeCare®, evidence-based program targeting CM, often implemented by social workers welfare settings. Maternal participants (N...
Abstract Background Maternal hormones, like testosterone, can strongly influence developing offspring, even generating long-term organizational effects on adult behavior; yet, the mechanisms facilitating these are still unclear. Here, we experimentally elevated prenatal testosterone in eggs of zebra finches ( Taeniopygia guttata ) and measured male aggression adulthood along with patterns neural gene expression (RNA-seq) DNA methylation (MethylC-Seq) two socially relevant brain regions...
This qualitative study explores the impact of emergency transition to remote education (ETRE) during COVID-19 pandemic on instructors and students through lens self-determination theory (SDT). A modified thematic analysis narratives from a cross-sectional survey revealed eight themes: Sense loss/grief, Role conflict, Helplessness, I had no choice, felt impossible, Lost connections, Am safe, They don’t care about me. Sub-themes expound their associated themes. Participant shared feelings...
In the Spring term of 2020, nearly 90% higher education institutions in United States were forced to transition from primarily face-to-face (F2F) instruction various modes remote or online response COVID-19 pandemic. State-funded colleges and universities Georgia mandated do same April which led a system-wide hiatus while instructors prepared return all-remote teaching. This study examined effects this Emergency Remote Instruction (ERI) at six Georgia, using survey completed by 910 who made...
Several papers have suggested that the Freshwater Cichlid Crenicara punctulata is capable of protogynous sex change. These studies provide behavioral data and descriptive details external morphology but lack information about gonadal histology, which essential for definitive evidence sequential hermaphroditism. Therefore, this study was designed to determine whether C. a hermaphrodite. The present included experiment, an isolation/transformation as well detailed analysis structure....
Abstract Informal learning environments often host teachers for opportunities, but little is known about the impact of these experiences on teacher professional development (PD). This article describes a unique collaborative PD experience between zoological park personnel and university faculty, examining content knowledge, attitudes, classroom lessons. Our findings suggest that improved science content, made no already high attitudes toward science. In light level self-reported satisfaction...
Educational experiences can be influenced by novel experiences, yet educators often overlook the influence novelty exerts on students. This quasi-experimental study manipulated prior knowledge before a zoo field trip for 210 urban 7th-grade students from 2 schools, 1 comprised mostly of low-socioeconomic status (SES) families and middle-SES families. Students participated in preparatory lessons, only which previewed trip-related content, thereby increasing half each school. Prior...
Brains Rule! Neuroscience Expositions, funded through a National Institute on Drug Abuse Science Education Partnership Award, has developed successful model for informal neuroscience education. Each Exposition is “reverse science fair” in which neuroscientists present short teaching modules to students. This study focuses results of assessments conducted with neuroscientist presenters during Expositions at two sites, Atlanta, Georgia and Corpus Christi, Texas. The effects participating the...
To strengthen the US scientific workforce, we aim to recruit and retain talented students in science, technology, engineering, math (STEM) fields, enhance success among from groups underrepresented STEM diversify workforce mirror population. Given that opportunities for authentic research may support advancement, seek maximize number of involved research. Our Behavioral Research Advancements Neuroscience (BRAIN) program tests hypothesis a team-based collaborative-learning model not only...
