This paper presents part of the findings from a comparative study on existing and proposed science curricula of grades IX-X in Bangladesh. It aims to explore relevant research to find out what ideas about science are recommended to include in school science curriculum, and then to compare the existing and proposed curricula in terms of ideas about…

Prize-winning scientist and bestselling author James Trefil explains why every U.S. citizen needs to be "scientifically literate" and, therefore, why schools must teach the fundamental principles of scientific literacy to every student. He lays out those principles straightforwardly, so that educators--and everyone who is interested in…

The development of the science of genetics through the confluence of separate theories is surveyed in this essay. An outline of classical genetics is emphasized. Interruptions in the continuity of development and the influence of genetics on the biological sciences and man as a social animal are discussed. (VW)

This history for molecular genetics and its explanation of DNA begins with an analysis of the Golden Jubilee essay papers, 1955. The paper ends stating that the higher nervous system is the one major frontier of biological inquiry which still offers some romance of research. (Author/VW)

A lab in Eastern North America conducted a study to determine the taxonomic relationship between deciduous trees and several species of oaks by calculating the similarity index of all species to be studied. The study enabled students to classify the different species of oaks according to their distinct characteristics.

This article describes the emerging field of metagenomics, a potent new tool that vastly expands the ability of scientists to study the myriad capabilities of microbial communities and the as yet unrecognized relationships and interactions of microbes with other forms of life and the environment. The birth of this exciting new field provides the…

This paper analyzes the formation of a new scientific discipline with regard to the intellectual and social activities of scientists in such development. (HS)

This essay describes how Francis Crick, ex-physicist, entered the field of biology and discovered the structure of DNA. Emphasis is upon the double helix, the sequence hypothesis, the central dogma, and the genetic code. (VW)

Science is among the most grandiose, the most magnificent playgrounds one can imagine. One can play with innumerable objects, turn them into composite objects, play with rules, combine rules in different ways, invent new rules, and build theoretical frameworks that reveal the essential simplicity and beauty of how different phenomena fit into a…

We show that the treatment of pendulum movement, other than the linear approximation,may be an instructive experimentally based introduction to the physics of non-linear effects. Firstly the natural frequency of a gravitational pendulum is measured as function of its amplitude. Secondly forced oscillations of a gravitational pendulum are…

In this article the authors resort to a qualitative analysis of the plot of science fiction stories about a group of scientists, written by two 11th-grade Earth and Life Science students (aged 17), and to semi-structured interviews, with the double purpose of diagnosing their conceptions of the nature of science (namely, as regards scientists'…

When students investigate science, they model, imitate, and perform science much as scientists do. Learning science in this way is best, according to the locus of control research. Based on this research, students need to develop an internal belief that they can control science outcomes and become a part of science through their own hands-on…

In the USA there is a contemporary discourse of crisis about the state of education and a parallel discourse that lays a large portion of the blame onto the poor quality of educational research. The solution offered is "scientific research." This article presents critiques of the core assumptions of the scientific research as secure argument.…

A psi-watcher's survey of current mind and consciousness research - from karate and kung fu to the kundalini hypothesis. (Editor)
