We have developed an upper-level undergraduate laboratory exercise that enables students to replicate a key experiment in developmental biology. In this exercise, students have the opportunity to observe live chick embryos and stain the apical ectodermal ridge, a key tissue required for development of the vertebrate limb. Impressively, every…

Purpose: The objective of this study was to investigate local injection with a hierarchically microstructured hyaluronic acid-gelatin (HA-Ge) hydrogel for the treatment of acute vocal fold injury using a rat model. Method: Vocal fold stripping was performed unilaterally in 108 Sprague-Dawley rats. A volume of 25 µl saline (placebo controls),…

This article presents a comparative exploration of news media portrayals of Indigenous environmental issues in Canada and the United States guided by a qualitative multimodal critical discourse analysis methodology. Theoretical framing was provided by Elliot Eisner's three curricula, Antonio López's visual literacy framework, and the broader…

Studies about equine therapies or equine experiential learning recommend that significantly more research, specifically longitudinal research, across age groups, genders, contexts and client cohorts needs to occur in diverse contexts. There exists diverse equine-related programs which engage with a range of cohorts, specifically; young children…

Prior studies on scaffolding for investigative inquiry practices (i.e. forming a question/hypothesis, collecting data, and analyzing and interpreting data [21]) revealed that students who received scaffolding were better able to both learn practices and transfer these competencies to new topics than were students who did not receive scaffolding.…

Researchers from different disciplines (e.g., physiological, psychological, philosophical) have investigated motivation using multiple approaches. For example, in physiology (the scientific study of the normal function in living systems such as biology), researchers may use "electrical and chemical stimulation of the brain, the recording of…

Difficulty performing age-appropriate motor skills affects up to 83% of children with autism spectrum disorder. This systematic review examined the effect of motor and physical activity intervention on motor outcomes of children with autism spectrum disorder and the effect of motor learning strategies on motor skill acquisition, retention, and…

Including animals in autism intervention is growing in both research and practice. A systematic literature review was conducted to collate and synthesize all empirical research on animal-assisted intervention (AAI) for autism published from 2012 to 2015. Findings from 28 included studies revealed that AAI programs generally include one animal per…

Animal experimentation is a controversial topic, especially among the general public and the scientific community. Thirty-eight undergraduate students attending the College of Veterinary Medicine--São Paulo State University in the municipality of Araçatuba, São Paulo, Brazil, were followed up between 2008 and 2011 and were asked to complete an…

The worry over urban children having lost their connection to nature is most often addressed with either initiatives of reinserting the "child back to nature" or with evidence aiming to prove that the worry is unfounded to begin with. Neither approach furthers our understanding of child-nature relations as continuing transformation of…

Adolescence is marked by a period of stress with a portion of these individuals experiencing problems with anxiety. There are physical and psychological benefits of using animal-assisted therapy (AAT) for decreasing anxiety, however, the research on this is limited. The current study expands on the AAT literature by studying the additive effects…

This case study explored dog-assisted reading with three middle-school special education students in a self-contained alternative school. Data collection conducted over a 15-month period included observations, interviews, and artifacts. In this study, reading with therapy dogs and their handlers, helped three adolescent readers with their reading…

This study examines the socio-emotional and cognitive impact of a three-month literacy centered humane education program on one second-grade classroom of socio-culturally and linguistically diverse children using a qualitative research design. Twenty-five children, ages 7-8 years, participated in a humane education program that focused on…

Analysis of mercury in fish is an interesting problem with the potential to motivate students in chemistry laboratory courses. The recommended method for mercury analysis in fish is cold vapor atomic absorption spectroscopy (CVAAS), which requires homogeneous analyte solutions, typically prepared by acid digestion. Previously published digestion…

Effectively communicating environmental issues to motivate visitors' behavior is critical for zoos to accomplish their missions. We examined the relationship between zoo visitors' environmental concern and agreement with messages framed by environmental concern. Findings from two zoos (N = 298; N = 400), using two message formats, provided nearly…
