Two separate bodies of research suggest that young children have (a) a broad tendency to reason about natural phenomena in terms of a purpose (e.g., Kelemen, 1999c) and (b) an orientation toward "creationist" accounts of natural entity origins whether or not they come from fundamentalist religious backgrounds (e.g., Evans, 2001). This…

A new transform proposed by Oyelami and Ale for impulsive systems is applied to an impulsive fish-hyacinth model. A biological policy regarding the growth of the fish and the hyacinth populations is formulated.

Scientists call the land along the edges of a river, stream, or lake a riparian zone. In this guide, riparian zone will be called the Green Zone. Riparian zones make up only a small part of land in the United States. But they are very important. They protect water quality and quantity, supply food and shelter for fish and wildlife, and provide…

Knowledge of animals may influence children's beliefs and behaviour toward them, thus building positive attitudes toward animals is one of main goals of environmental education programmes. Although keeping animals contributes to the increase of children's positive attitudes toward wild animals, pet owners show similar negative attitudes toward…

This paper is based upon a laboratory exercise designed for biology students in secondary schools or those taking introductory biology laboratory courses in colleges and universities. This exercise requires a set of calipers, a calculator and populations of snail shells collected either from the wild or obtained from a biological supply house. The…

Children's understanding about animal internal structure can be affected by several factors which are poorly understood by teachers. We conducted a large sample study (n=702) of children aged 6-16 years (Grades 1-9) examining children's responses to animals of various size, species and dimensions (2D and 3D objects), and exploring factors which…

This paper evaluated the level of adoption of aquaculture technology extended to farmers in Imo State, Nigeria. To improve aquaculture practice in Nigeria, a technology package was developed and disseminated to farmers in the state. This package included ten practices that the farmers were supposed to adopt. Eighty-two respondents were randomly…

Human cognition is founded, in part, on four systems for representing objects, actions, number, and space. It may be based, as well, on a fifth system for representing social partners. Each system has deep roots in human phylogeny and ontogeny, and it guides and shapes the mental lives of adults. Converging research on human infants, non-human…

The development of visual interaction between mother and infant has received much attention in developmental psychology, not only in humans, but also in non-human primates. Recently, comparative developmental approaches have investigated whether the mechanisms that underlie these behaviors are common in primates. In the present study, we focused…

In this article, the author presents three themes that can form the basis for exciting world language instruction in Spanish, French, and Chinese at any grade level. These three themes (the prehistoric world; endangered species; and space exploration) use basic science as a context for communication that generates student excitement and enthusiasm…

In a collaborative effort between university researchers and high school science teachers, an inquiry-based laboratory module was designed using two species of insecticidal nematodes to help students apply scientific inquiry and elements of thoughtful experimental design. The learning experience and model are described in this article. (Contains 4…

It's the first day of the "Animals" unit for Tami Brester's third-grade class and the first day her students are using Glossopedia, a free online multimedia science encyclopedia. But you wouldn't know that from observing the kids, who are excitedly researching animals on the internet. This is inquiry-based learning of a special kind, incorporating…

When asking about animals, it is hard to find a person who doesn't recall a beloved pet or share that they've always loved dolphins, snakes, or ladybugs. A study of animals in an early childhood classroom, then, would seem an easy entry into science explorations with children. The article includes reflections on teaching to address the gaps…

Volume 2 begins with Chapter 28 and the coeducation of the sexes in the United States. Other chapters cover: (1) the present educational movement in the Philippine Island by Fred W. Atkinson, general superintendent of public instruction in the Philippines; (2) list of foreign universities and other institutions of higher education; (3) general…

This science brief reports on a study that identified the effects of different experiences on critical periods of learning during early brain development. The study found that the presence of corticosterone in a part of the brain called the amygdala determined whether a normally painful experience was learned as an attractive or fearful event.…
