"Science is a process of discovering and exploring the natural world. Exploration occurs in the classroom, laboratory or in the field. As part of your science class, you will be doing many activities and investigations that will involve the use of various materials, equipment, and chemicals…" (NSTA, 2010). Safety is always of utmost…

A number of experimental paradigms use in vitro brain slices to test for changes in synaptic transmission and plasticity following a behavioral manipulation. For example, a number of previous studies have reported a variety of effects of environmental enrichment (EE) exposure on field potential responses in hippocampal slices, but in no study was…

Short acquisition-extinction intervals (immediate extinction) can lead to either more or less spontaneous recovery than long acquisition-extinction intervals (delayed extinction). Using rat subjects, we observed less spontaneous recovery following immediate than delayed extinction (Experiment 1). However, this was the case only if a relatively…

Central nervous networks, be they a part of the human brain or a group of neurons in a snail, may be designed to produce distinct patterns of movement. Central pattern generators can account for the development and production of normal vocal signals without auditory feedback in non-songbirds. Songbirds need auditory feedback to develop and…

Song production in songbirds is a model system for studying learned vocal behavior. As in humans, bird phonation involves three main motor systems (respiration, vocal organ and vocal tract). The avian respiratory mechanism uses pressure regulation in air sacs to ventilate a rigid lung. In songbirds sound is generated with two independently…

Individual vocal recognition behaviors in songbirds provide an excellent framework for the investigation of comparative psychological and neurobiological mechanisms that support the perception and cognition of complex acoustic communication signals. To this end, the complex songs of European starlings have been studied extensively. Yet, several…

Two matching-to-sample (MTS) and four same/different (S/D) experiments employed tests to distinguish between item-specific learning and relational learning. One MTS experiment showed item-specific learning when concept learning failed (i.e., no novel-stimulus transfer). Another MTS experiment showed item-specific learning when pigeons'…

The author's school is fortunate to have two therapy dogs, Daisy and Rosie, both West Highland terriers (Westies). Daisy is such a comfort to students when they are sad, scared, or just in need of a quiet friend. She assists students with special needs as well as students whose needs are special. In this article, the author describes how she…

Within the past decade, giant pouched rats have been used successfully to detect landmines. This manuscript summarizes how these rats are trained and used operationally. The information provided is intended to be of practical value toward strengthening best practices in using "Cricetomys" for humanitarian purposes while simultaneously…

The author examines the role of culture in education in historical perspective to suggest the conditions required to promote generalized educational reform. Although deliberate instruction appears to be a ubiquitous characteristic of human beings, schools arise only when large numbers of people begin to live in close proximity, using technologies…

We trained two bonobos to discriminate among occluded, complete, and incomplete stimuli. The occluded stimulus comprised a pair of colored shapes, one of which appeared to occlude the other. The complete and incomplete stimuli involved the single shape that appeared to have been partially covered in the occluded stimulus; the complete stimulus…

Male zebra finches learn to sing songs that they hear between 25 and 65 days of age, the sensitive period for song learning. In this experiment, male and female zebra finches were exposed to zebra finch songs either before (n = 9) or during (n = 4) the sensitive period. Following song exposure, recognition memory for the songs was assessed with an…

In this inquiry-based activity, students catalog external and internal characteristics of four different classes of animals during dissection exercises. On the basis of their accumulated data, students compare and contrast the animals, devise a phylogenetic tree, and provide reasonable characteristics for extinct transitional organisms. (Contains…

Formal education in Western society is firmly rooted in humanist ideals. "Becoming human" by cultivating certain cognitive, social, and moral abilities has even symbolised the idea of education as such in Enlightenment philosophical traditions. These ideas are increasingly coming under scrutiny by posthumanist theorists, who are addressing…

Nonfiction stories of animal compassion were used in this literacy-social studies integrated lesson to address both efferent and aesthetic stances in transmediation of text from picture books to maps. Preservice early childhood and elementary teachers chose places from the nine recent children's stories, symbolizing them on a map while…
