Wilding, Craig – Biochemistry and Molecular Biology Education, 2018
The teaching of quantitative genetic variation in the undergraduate laboratory practical environment can be difficult as, for quantitative phenotypes that are under the control of multiple loci, detection of phenotypic differences caused by individual variants is problematical without large samples, impractical in such classes. Pet dogs provide a…

Casla, Alberto Vicario; Zubiaga, Isabel Smith – Biochemistry and Molecular Biology Education, 2010
Students often have an oversimplified view of biological facts, which may hinder subsequent understanding when conceptual complexity gives rise to cognitive conflicts. To avoid this situation here, we present a PBL approach for the analysis of Ehlers-Danlos syndrome (EDS), which integrates a variety of topics in cell biology, genetics, and…

Milanick, Mark; Graham, Kerri; Wessel, Melissa – American Biology Teacher, 2013
Students are provided with a mystery concerning dogs that are paralyzed. This motivates a laboratory exercise to measure parameters from the dog's "blood" to determine whether the paralysis is due to pesticide poisoning or an autoimmune attack on nerve myelin. Most of the materials are available from the grocery store. The real-world nature of the…

Clotfelter, Ethan D.; Hollis, Karen L. – American Biology Teacher, 2008
Cognition is a general term describing the mental capacities of an animal, and often includes the ability to categorize, remember, and communicate about objects in the environment. Numerous regions of the telencephalon (cerebral cortex and limbic system) are responsible for these cognitive functions. Although many researchers have used traditional…

Catley, Kefyn M.; Phillips, Brenda C.; Novick, Laura R. – Research in Science Education, 2013
The biological community is currently undertaking one its greatest scientific endeavours, that of constructing the Tree of Life, a phylogeny intended to be an evidenced-based, predictive road map of evolutionary relationships among Earth's biota. Unfortunately, we know very little about how such diagrams are understood, interpreted, or used…

Burger, Lance – Mathematics Teacher, 2010
Constructivism has constituted a predominant philosophical trend in mathematics education, but its implementation in the classroom has proven to be "far more difficult than the reform community acknowledges". This difficulty may be due in part to administrative cultures that might insist on more procedural types of instruction aimed at testing, in…

Fox-Parrish, Lynne; Jurin, Richard R. – Journal of Environmental Education, 2008
The authors used a case-study methodology to explore the perceptions of 30 9th-grade biology students relative to black-tailed prairie dogs. The case study, which involved classroom- and field-based experiences that focused on black-tailed prairie dogs, revealed 3 major themes: apathy, egocentrism, and naive conceptions. The authors had hoped that…

Grant, Michael C.; Pirrto, John – Journal of Science Education and Technology, 1994
Describes a successful interdepartmental program at a major research-oriented university that melds freshman writing with freshman biology. Extensive, repeated feedback on individual student writing projects from two instructors appears to work synergistically so that student learning is significantly enhanced. Particulars derived from five years…

Curran, Mary Carla; Richlen, Mindy L. – Science Activities: Projects and Curriculum Ideas in STEM Classrooms, 2019
Marine phytoplankton comprise the foundation of oceanic food webs and generate most of the Earth's oxygen. Of the many phytoplankton species in the ocean, a few dozen produce potent toxins, and at high concentrations can form what are called Harmful Algal Blooms (HABs) or "red tides" that can discolor marine waters. Managers and…

Frazier, Loy W. – Physiology Teacher, 1977
Lists materials and methods for an experiment that demonstrates the concept of glomerular filtration rate (GFR) using anesthesized dogs. In the dog, GFR is equivalent to the renal plasma clearance of exogenous creatinine. (CS)

Herrmann, Patricia A.; Medin, Douglas L.; Waxman, Sandra R. – Cognition, 2012
The current study examines 3- and 5-year-olds' representation of the concept we label "animal" and its two nested concepts--"animal"[subscript contrastive] (including only non-human animals) and "animal"[subscript inclusive] (including both humans and non-human animals). Building upon evidence that naming promotes object categorization, we…

van Rooy, Wilhelmina – Teaching Science, 2013
The fatal effect of the Hendra virus was noticed first in Queensland, Australia in 1994 when several horses died from an "unidentified cause". This was followed by the death of trainers and veterinarians called to assist affected horses. It is now known that the "unidentified cause", is a virus harboured in native Australian…

Bowers, Jeffrey S. – Psychological Review, 2009
A fundamental claim associated with parallel distributed processing (PDP) theories of cognition is that knowledge is coded in a distributed manner in mind and brain. This approach rejects the claim that knowledge is coded in a localist fashion, with words, objects, and simple concepts (e.g. "dog"), that is, coded with their own dedicated…
