The study investigated cognitive and motivational effects of two educational interventions, a conventional versus a student-oriented approach. We monitored the impact on the cognitive achievement outcome and the motivation of students. Both approaches dealt with the subject of birds and bird flight; the student-oriented approach consisted of a…

Fish consumption advisories fail to adequately help communities address the benefits and risks of eating potentially contaminated fish. We engaged community members and relevant institutions in identifying and implementing more effective risk communication in Michigan's rural Upper Peninsula. In 2004-2005, we collected data in four Michigan…

The purpose of this qualitative study was to determine agricultural science teacher comfort with a new high school Advanced Life Science: Animal course and determine their perceptions of student impact. The advanced science course is eligible for college credit. The teachers revealed they felt confident of their science background in preparation…

Looking after pets provides several benefits in terms of children's social interactions, and factual and conceptual knowledge about these animals. In this study we investigated effects of rearing experiences on children's factual knowledge and alternative conceptions about animals. Data obtained from 1,541 children and 7,705 drawings showed very…

Forward blocking is one of the best-documented phenomena in Pavlovian animal conditioning. According to contemporary associative learning theories, forward blocking arises directly from the hardwired basic learning rules that govern the acquisition or expression of associations. Contrary to this view, here the authors demonstrate that blocking in…

The rabbit nictitating membrane (NM) response underwent successive stages of acquisition and extinction training in both delay (Experiment 1) and trace (Experiment 2) classical conditioning. In both cases, successive acquisitions became progressively faster, although the largest, most reliable acceleration occurred between the first and second…

The purpose of the present study was to examine the relative adequacy of the dry mouth vs. emotional theories of SIP using the desalivate rat. (Author)

"Eukiefferiella" and "Tvetenia" are closely related genera belonging to the subfamily Orthocladiinae within the Chironomidae, a family of non-biting midges. All known larvae in these genera are aquatic, being found predominantly in running water. Most species prefer cold, swift-flowing, well-oxygenated streams. Although larvae…

Food preferences set by delayed visceral effects facilitate memory research and predator control. (Author/RH)

Analogies can be useful in the study of behavior, physiology, and comparative evolution. Dangers in mistaking a homology for an analogy are discussed. (RH)

The diverse effects of light on plants and animals are reviewed in general. The conditioned behavior of fruit flies is also discussed. For the second article in this series, see SE 511 548. (DT)

In this second book, the author presents animal physiology. The teacher and parent will observe, that in doing this the author brings out quite prominently the analogies that exist between the animal and the vegetable world in the operations of life. Such analogies are always interesting to the child as well as to the adult, and the consideration…

This compendium is designed for use in grammar and high schools. It is introductory to the author's larger zoology text. Though partly rewritten, and with additions regarding the habits of birds and mammals, portions of the larger book have been retained, the more difficult parts being omitted so as to adapt it for younger pupils, or those whose…
