A simple low cost demonstration experiment is performed using common apparatus in order to show various flexural patterns and to give a dynamical measure of Young's modulus. (Contains 4 figures.)

The collection of articles in this special issue and related studies over the past decade provides a fine example of the substantial progress that has been made in our understanding and remediation of mathematical learning disabilities and difficulties since 1993 (Geary, 1993). The originally proposed procedural and retrieval deficits have been…

Geometry is an area in which Australian students performed particularly poorly on the 2007 Trends in International Mathematics and Science Study (TIMSS). One innovative area of recreational geometry that has rich potential to engage and challenge a wide variety of students is "impossible geometry." An impossible geometric object is a…

A wealth of empirical evidence has now accumulated concerning animals' categorizing photographs of real-world objects. Although these complex stimuli have the advantage of fostering rapid category learning, they are difficult to manipulate experimentally and to represent in formal models of behavior. We present a solution to the representation…

The majority of studies in second-language (L2) speech processing have involved unimodal (i.e., auditory) input; however, in many instances, speech communication involves both visual and auditory sources of information. Some researchers have argued that multimodal speech is the primary mode of speech perception (e.g., Rosenblum 2005). Research on…

According to Maxine Greene (1988), aesthetic education is "integral to the development of persons--to their cognitive, perceptual, emotional, and imaginative development" (p. 7). The purpose of this paper is to present the developing sense of self that pre-service teachers experienced through an aesthetic entry point, the 9/11 mural by…

One of the largest challenges of teaching astronomy is bringing the infinite scale of the universe into the four walls of a classroom. However, concepts of astronomy are often the most interesting to students. This article focuses on an alternative method for learning about stars by exploring visible characteristics of the constellation Orion and…

From her first encounter with stereoscopic 3D technology designed for classroom instruction, Megan Timme, principal at Hamilton Park Pacesetter Magnet School in Dallas, sensed it could be transformative. Last spring, when she began pilot-testing 3D content in her third-, fourth- and fifth-grade classrooms, Timme wasn't disappointed. Students…

One of the strong trends in medical education today is the integration of the humanities into the basic medical curriculum. The anatomy program is an obvious choice for using the humanities to develop professionalism and ethical values. They can also be used to develop close observational skills. Many medical schools have developed formal art…

We comment on Goldstein, Davidoff, and Roberson's replication and extension ("Journal of Experimental Child Psychology, 102", 219-238 [2009]) of our study of the effect of toddlers' color term knowledge on their categorical perception (CP) of color ("Journal of Experimental Child Psychology, 90", 114-141 [2005]). First, we discuss how best to…

Christian N. L. Olivers, winner of the Award for Distinguished Scientific Early Career Contributions to Psychology, is cited for outstanding research on visual attention and working memory. Olivers uses classic experimental designs in an innovative and sophisticated way to determine underlying mechanisms. He has formulated important theoretical…

Counseling students must learn and practice basic counseling skills, including attending, listening, empathizing, and demonstrating warmth and respect. For online educators, providing opportunities for students to develop these skills in realistic counseling situations can be difficult. Victoria L. Walker and Amanda Rockinson-Szapkiw describe how…

This paper tries to demonstrate that it is not reasonable to judge the quality of pictures that a camera can produce just by the number of pixels that the sensor has. It does so by trying to relate the number of pixels in a picture to the resolution that the eye can see at various distances away from prints of different size.

M. Singh and B. L. Anderson proposed a perceptual theory of achromatic transparency in which the perceived transmittance of a perceived transparent filter is determined by the ratio of the Michelson contrast seen in the region of transparency to that of the background seen directly. Subsequently, B. L. Anderson, M. Singh, and J. Meng proposed that…

All of the data reported in Robilotto, Khang, and Zaidi (2002) Robilotto and Zaidi (2004), and Singh and Anderson (2002) are consistent with Robilotto and Zaidi's theory that perceived transparency (or opacity) is determined by the perceived contrast of the filter region. Kasrai and Kingdom's (2001) results also appear largely consistent with the…
