We believe a lack of transparency undermines both the credibility of, and interest in, stated choice studies among policy makers. Unlike articles reporting the results of contingent valuation studies, papers in the stated choice literature rarely present simple tabulations of raw response data (that is, a table or graph showing the percentage of…

In this article, the author discusses how global warming makes the leap from the headlines to the classroom with thought-provoking science experiments. To teach her fifth-grade students about climate change, the author starts with a discussion of the United States' local climate. They extend this idea to contrast the local climate with others,…

It is often not apparent what people ought to do. Three experiments explored cues that children and adults may use to identify conventional obligations. Experiment 1 addressed the hypothesis that young children identify obligations with expected outcomes. Although preschool-aged (4-5 years) children often expected consistency, they and school-aged…

This paper describes the development and validation of a new 40-item Internet Attitude Scale (IAS), a one-dimensional inventory for measuring the Internet attitudes. The first experiment initiated a generic Internet attitude questionnaire, ensured construct validity, and examined factorial validity and reliability. The second experiment further…

Learning to understand the content and meaning of physics' concepts is one of the main goals of physics education. In achieving this understanding, the creation of quantities through quantitative measurements, or rather through quantifying experiments, is a key process. The present article introduces a didactical reconstruction for understanding…

Since 1988 the Interactive NASA Space Physics Ionospheric Radio Experiment, or INSPIRE, has given students the opportunity to build research-quality VLF radio receivers and make observations of both natural and stimulated radio waves in the atmosphere. Any high school science class is eligible to join the INSPIRE volunteer observing network and…

Two groups of undergraduate students, matched for reading skill but differing in spelling ability, participated in three experiments with the aim of exploring the causes of differences in spelling skill in this population. In the first experiment participants were presented with a range of tasks to investigate the possibility that the poor…

Recent research has shown that the ability to inhibit irrelevant information is related to Working Memory (WM) capacity. In three experiments, we explored this relationship by using a list-method directed-forgetting task (DF) in participants varying in WM capacity. Contrary to predictions, in Experiment 1, DF effects were only found for…

Assessing speech discrimination skills in individual infants from clinical populations (e.g., infants with hearing impairment) has important diagnostic value. However, most infant speech discrimination paradigms have been designed to test group effects rather than individual differences. Other procedures suffer from high attrition rates. In this…

It has been suggested that infants respond preferentially to infant-directed speech because their auditory sensitivity to sounds with extensive frequency modulation (FM) is better than their sensitivity to less modulated sounds. In this experiment, auditory thresholds for FM tones and for unmodulated, or pure, tones in a background of noise were…

Advances in biology are prompting new discoveries in the biotechnology, pharmaceutical, medical technology, and chemical industries. This paper presents a detailed description of an anion exchange chromatography experiment using a pair of colorful proteins and summarizes the effect of operating parameters on protein separation. This experiment…

The analysis of a Murder case study can be used in general chemistry or nonscience major chemistry courses to teach data handling and analysis in a non-laboratory context. This case study will help students to respond more enthusiastically and with more interest to a set of material placed before them related to a real case rather than…

A laboratory exercise was developed by using variable temperature powder X-ray diffraction (XRD) to determine [alpha] for MgO (periclase)and was tested in the Applied Physical Chemistry and Materials Characterization Laboratories at James Madison University. The experiment which was originally designed to provide undergraduate students with a…

We compared the ability of auditory, visual, and audiovisual (bimodal) exogenous cues to capture visuo-spatial attention under conditions of no load versus high perceptual load. Participants had to discriminate the elevation (up vs. down) of visual targets preceded by either unimodal or bimodal cues under conditions of high perceptual load (in…

This paper deals with a brief introduction to major remarkable discoveries of the "soliton" and the "inverse scattering transform" in the 1960s. The discovery of the soliton (or the solitary waves) began with the famous physical experiments of the Scottish Engineer and Naval Architect John Scott Russell in the Glasgow-Edinburgh…
