In this paper we discuss the development and running of a residential animal behaviour field trip. The trip has a number of elements that challenge and develop the students. First, this trip is open to students at levels two, three and M. This allows us to engineer a certain amount of peer assisted learning. Second, the students live together and…

This study investigated the effectiveness of three different instructional materials for learning how to identify fish at the species level in a blended classroom and out-of-classroom scenario. A sample of 195 first-year students of biology or geoecology at the University of Tuebingen participated in a course on identification of European…

When doing spring planting activities, what does a teacher do while waiting for the plants to grow? This waiting time is a golden opportunity to explore another side of gardening--the creatures that make it all possible. Insects are an integral part of everyday world, having existed for over 300 million years; they are the most common animal on…

We compared the performance of 3- and 5-year-old children with that of chimpanzees in two tasks requiring collaboration via complementary roles. In both tasks, children and chimpanzees were able to coordinate two complementary roles with peers and solve the problem cooperatively. This is the first experimental demonstration of the coordination of…

The diversity of life on Earth is a fundamental concept in biology, but it can be difficult to explore in the confines of an elementary school classroom. A great place to start is by getting students outside to observe the diversity in their own backyards. The author served as a scientist-in-residence for one year at an elementary school in…

Change due to natural disturbances and disasters, population growth and decline, economic crises, and environmental and climate change creates significant cultural challenges. Rapid change and the transformation it brings also involve complex relationships between sovereign tribes, resources, and the global system. This article explores how salmon…

Kv4.2 channels contribute to the transient, outward K[superscript +] current (A-type current) in hippocampal dendrites, and modulation of this current substantially alters dendritic excitability. Using Kv4.2 knockout (KO) mice, we examined the role of Kv4.2 in hippocampal-dependent learning and memory. We found that Kv4.2 KO mice showed a deficit…

Two groups of year 6 pupils (age 10-11 years) each experienced science practical lessons that were essentially identical but for one difference: one group (theory-led) were told by the teacher what result they should expect, and the other group (hypothetico-deductive) were not. The theory-led group demonstrated experimental bias, recording results…

The marine fishery in Senegal, West Africa, is a major source of employment and food security. It currently faces the consequences of ecological degradation. This paper examines job satisfaction among small-scale purse seine fishers, who constitute one of the dominant fishing metiers in Senegal. The research sample consists of 80 purse seine…

Lobster fishing (targeting the spiny lobster "Panulirus argus") is an important economic activity throughout the Wider Caribbean Region both as a source of income and employment for the local population as well as foreign exchange for national governments. Due to the high unit prices of the product, international lobster trade provides a…

Purpose: Breathing and swallowing problems affect elderly people and may be related to age-associated tongue dysfunction. Hypoglossal motoneurons that innervate the tongue receive a robust, excitatory serotonergic (5HT) input and may be affected by aging. We used a rat model of aging and progressive resistance tongue exercise to determine whether…

It is important that Extension education programs be directed at clientele new to the turfgrass industry. A 1-day Basic Training: Turf Management seminar was created in 2006 to provide education to those new to the turfgrass industry. The seminar covered the basics of turfgrass management including growth, physiology, fertilization, cultural…

In this article, the author describes how her second-graders created their cool polar bears. The students used the elements of shape and texture to create the bears. They used Monet's technique of dabbing paint so as to give the bear some texture on his fur.

The neural cell adhesion molecule (NCAM) is known to play a role in developmental and structural processes but also in synaptic plasticity and memory of the adult animal. Recently, FGL, a NCAM mimetic peptide that binds to the Fibroblast Growth Factor Receptor 1 (FGFR-1), has been shown to have a beneficial impact on normal memory functioning, as…

While much developmental research has focused on the strategies that children employ to recognize faces, less is known about the principles governing the organization of face exemplars in perceptual memory. In this study, we tested a novel, child-friendly paradigm for investigating the organization of face, bird and car exemplars. Children ages…
