Scientists have a particularly difficult time explaining warming trends in Antarctica--a region with a relatively short history of scientific observation and a highly variable climate (Clarke et al. 2007). Regardless of the mechanism of warming, however, climate change is having a dramatic impact on Antarctic ecosystems. In this article, the…

Discusses why publications by Thomas Kuhn had little impact in the field of science history. (Author/CCM)

Discusses Kuhn's model of scientific theory change. Documents Kuhn's move away from conceptual relativism and rational relativism. Provides an analysis of his present ontological form of relativism. (CCM)

Chemistry is considered to be a combination of principles and facts that causes the formation of the earth and its layering that governs the ecosystem, which underlie the properties of materials and of living organisms. Laboratory classes do not help students to understand the way in which chemical principles affect their universe.

In an attempt to better support the mathematics and science learning experiences of preservice teacher candidates, a new course of study was created as part of a teacher certification program at a mid-Atlantic liberal art university. Entitled Investigations in Science and Mathematics, the two semester course adopted an integrated inquiry and…

This article reviews the significance of Jacques Ranciere's work for methodological debates in the social sciences, and education specifically. It explores the implications of constructing research as an aesthetic, rather than primarily a methodological, endeavour. What is at stake in this distinction is the means by which research intervenes in…

The study investigated tenth-, eleventh-, and twelfth-grade students' alternative ideas relating to the motion of a body travelling in the field of gravity with an initial horizontal velocity. The sample of the study consisted of 40 tenth-grade students, and 33 and 40 eleventh-grade students that attended different sections of upper secondary…

A microscale laboratory experiment to investigate the formation and utility of microemulsions is described. Microemulsions are technologically important fluids that can reduce the use of toxic organic solvents. In the experiment, students prepare a microemulsion and compare the solubility of sudan III dye in the microemulsion and in dodecane. They…

This study took place during a First Year Seminar course where 20 incoming college freshmen studied the central topic of the nature of science within the context of biological evolution. The instructor researched students' understandings in the nature of science as they progressed through the course by examining a variety of qualitative and…

This article is a review of applications of phenomenology, as a philosophy of knowledge and qualitative research approach, to the field of science education (SE). The purpose is to give an overview of work that has been done as well as to assess it and discuss its possibilities of future development. We ask: what attempts for connecting…

The benefit of selecting educational programs based on proven research is that they can deliver what is promised if they are implemented as intended. These research-based educational programs are like the medicine that your physician prescribes. Improvement in the medical condition requires that the medicine be taken as prescribed. These…

Our physics students like to watch a ball bouncing underwater. They do this by dropping a weighted plastic ball into a 1000-ml cylinder filled with a linearly stratified salt-water solution at room temperature. The ball oscillates and comes to rest at about mid-depth. Its motion is analogous to the damped vertical oscillations of a mass hanging…

Here is a quick way to measure the index of refraction of water using the phenomenon of total internal reflection.
