This paper presents an active learning approach that focuses on practical investigation of the ecosystem of tidal flats using 3D modeling and printing for biology students in order to enhance understanding of natural selection. The learning approach for the study followed a 5-step procedure: i) learning about 3D modeling and printing, ii)…

Currently available (classical) testing procedures for the network autocorrelation can only be used for falsifying a precise null hypothesis of no network effect. Classical methods can be neither used for quantifying evidence for the null nor for testing multiple hypotheses simultaneously. This article presents flexible Bayes factor testing…

Virtual reality (VR) technology has been capturing the public imagination for decades. VR software applications that allow for interactive immersion are emerging as a renowned medium in many areas, including educating the public in biochemistry-related subjects via public engagement events. This report provides information about an immersive,…

The objective of our program is to foster and facilitate authentic research experiences in middle and high school science courses. We do so by providing students with a complete experience in scientific experimentation and communication. The centerpiece is a set of experiment modules in which students investigate the effects of toxic chemicals on…

Outbreaks of highly pathogenic avian influenza have become endemic, crippling trade and livelihood for many, and in rare cases, resulting in human fatalities. It is imperative that up-to-date education and training in accessible and interactive formats be available to key target audiences like poultry producers, backyard flock owners, and…

This article highlights how two institutions--Redlands Community College (RCC) and Auburn University--teamed up to create a virtual world called Eagle Island, where learners enter to learn all they need to know about poultry science. Eagle Island, located in Second Life, provides an opportunity to tour a real-life food processing…

The present article deals with the problem of combined harvesting of a Michaelis-Menten-type ratio-dependent predator-prey system. The problem of determining the optimal harvest policy is solved by invoking Pontryagin's Maximum Principle. Dynamic optimization of the harvest policy is studied by taking the combined harvest effort as a dynamic…

The course "Management of Fluid and Electrolyte Disorders" is an applied physiology course taught using lectures and paper-based cases. The course approaches fluid therapy from both basic science and clinical perspectives. While paper cases provide a basis for application of basic science concepts, they lack key components of genuine clinical…

Physics instruction that is student oriented will generate a long-term individual interest and therefore a lifelong openness to science. Phenomena of nature are part of the fields of interest which provide context leading to greater student interest. In this paper we present the locomotion of fish and sperm in a way which can be used to teach in…

Laboratory exercises are intended to illustrate concepts and add an active learning component to courses. Since the 1980s, there has been a decline in animal laboratories offered in conjunction with medical physiology courses. The most important single reason for this is cost, but other contributing factors include the development of computer…

Describes a program which simulates animal pharmacology experiments involving "all-or-none" responses. Use of the Applesoft BASIC program in the pharmacology teaching laboratory provides students with a rapid and economical way to gain experience in the design and statistical analysis of quantal dose-response experiments. Information on…

Discusses use of computer simulation as an archeological tool for research and teaching involving the remains of prehistoric game animals to aid in understanding effects of various strategies of prehistoric hunters on populations of game animals. A simulation involving possible vicuna hunting strategies is described. (MBR)

Describes use of computer simulation which generates bird songs so that students can analyze song motifs and sequences as an introduction to descriptive analysis of behavior in an animal behavior course. Advantages of the simulation are discussed together with computer hardware/software needed and data presentation, analysis, and generation…

Describes a kangaroo simulation which can be adapted for use with radio tracking activities for other animals. Outlines procedures and information to help implement the activity. Provides a map of Australia, calculations, and sample kangaroo movement data. (RT)

Describes some alternatives to dissection offered to teachers through the National Anti-Vivisection Society (NAVS) and other sources. These include models, CD-ROMs, and software that enable students to click on scalpels, scissors, and other instruments to cut through videotaped specimens. Also details the Dissection Hotline and the Dissection…
