Despite a decline in popularity within US society, posters continue to hold a prominent place within middle and high school science classrooms. Teachers' demand is satisfied by governmental and non-profit science organizations that produce and disseminate posters as tangible products resulting from their research, and instruments to communicate…

A student might find a certain representational format (e.g., diagram, text) more attractive than other formats for learning. Computer technology offers opportunities to adjust the formats used in learning environments to the preferences of individual learners. The question addressed in the current study was: does the match between a student's…

This article explores the advantages and limitations of using the interactive whiteboard to enhance teaching and learning. The author observed two teachers use it and discusses their feelings about it. Also included is a discussion of previous research on this technological tool.

The role of the "foraging" ("for)" gene, which encodes a cyclic guanosine-3',5'-monophosphate (cGMP)-dependent protein kinase (PKG), in food-search behavior in "Drosophila" has been intensively studied. However, its functions in other complex behaviors have not been well-characterized. Here, we show experimentally in "Drosophila" that the "for"…

Repetition blindness (RB) for nonwords has been found in some studies, but not in others. The authors propose that the discrepancy in results is fueled by participant strategy; specifically, when rapid serial visual presentation lists are short and participants are explicitly informed that some trials will contain repetitions, participants are…

Picturebooks tell stories in both words and pictures. Interacting with the printed word, the technical elements of illustration--color, line, shape and composition--work to establish and enhance the story. Sometimes simply by adding description of characters and setting, and, at times, by challenging the veracity of the text with ironic or…

This article discusses and evaluates the inclusion of ethics learning modules in a graduate- level visual design theory course. Modules were designed as a part of an NEH grant. Students grappled with case studies that probed the ethics of visuals at the crux of the BP oil refinery accident, NASA space shuttle disasters, the Enron collapse, and…

The purpose of this study was to determine the effect of four different design layouts of the New York State elementary science learning standards on user processing time and preference. Three newly developed layouts contained the same information as the standards core curriculum. In this study, the layout of the core guide is referred to as Book.…

This study consists of two instructional experiments. Within the framework of dual coding theory, the study compares the learning effects of two instructional encoding methods used in Chinese vocabulary instruction among students learning beginning Chinese as a foreign language. One method uses verbal encoding only, and the other method uses…

The genetic factor structure of a range of learning measures was explored in twin children, recruited in preschool and followed to Grade 2 ("N"?=?2,084). Measures of orthographic learning and word reading were included in the analyses to determine how these patterned with the learning processes. An exploratory factor analysis of the…

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…

The currency of our visual experience consists not only of visual features such as color and motion, but also seemingly higher-level features such as causality--as when we see two billiard balls collide, with one causing the other to move. One of the most important and controversial questions about causal perception involves its origin: do we…

This article provides details about a comprehensive assignment for teaching sales letters in a business communication course. During the past 5 years, this assignment has evolved, moving beyond one that focused almost exclusively on strategies for making the letter persuasive, and therefore effective, to an expanded form that devotes time and…

Imaginative and attractive, cutting edge in its conception, this text explicates a model for the integration of language arts and literacy education based on the notion of framing. The act of framing--not frames in themselves--provides a creative and critical approach to English as a subject. "Re-framing Literacy" breaks new ground in the language…
