Discussion of the growth of institutional image collections focuses on the development of a visual thesaurus to provide access to the photographic archive of the National Aeronautics and Space Administration (NASA). Addresses specific access problems, including the accurate and rapid description of images entering collections, and searching…

This research, part of the ongoing study to better understand Web page ranking on the Web, looks at a Web page as a graph structure or Web graph, and classifies different Web graphs in the new coordinate space (out-degree, in-degree). Google's Web ranking algorithm (Brin & Page, 1998) on ranking Web pages is applied in this new coordinate…

Presents concrete graphing experiences from the United States. (Author/CCM)

Examining a range of visual images of executions, both legal (the executions of convicted murderers) and extralegal (the lynchings of innocent African Americans), in still photographs and in Hollywood films, the authors suggest that while such images may flatten and neutralize the popular debates and politics surrounding the issues, this is not…

Clinicians routinely report fewer features in a case than they subsequently agree are present. The authors report studies that assess the effect of considering a more comprehensive description than physicians usually offer. These comprehensive descriptions were generated from photographs of dermatology and internal medicine and were complete and…

Longitudinal data analyses can be usefully supplemented by the plotting of individual growth curves. Unfortunately, such graphics can be challenging and tedious to produce. This article presents and demonstrates a SAS macro designed to automate this task. The OLStraj macro graphically depicts ordinary least squares (OLS)-estimated individual…

In Experiment 1, 24-month-old toddlers were taught a new word ("whisk") through the labeling of a picture of a whisk. After repeated pairings of the word and picture, participants were shown the picture and a real whisk and asked to indicate the whisk. They took the word to refer to the real object rather than to the picture. Experiment 2…

William Playfair's pie chart is more than 200 years old and yet its intellectual origins remain obscure. The inspiration likely derived from the logic diagrams of Llull, Bruno, Leibniz, and Euler, which were familiar to William because of the instruction of his mathematician brother John. The pie chart is broadly popular but--despite its common…

A spreadsheet simulation of a modern particle detector has been developed and can be readily used as an instructional tool in the physics classroom. The spreadsheet creates a three-dimensional model that can be rotated and helical trajectories can be highlighted. An associated student worksheet is also presented.

Using a low-inference observational instrument, the authors empirically described and compared pedagogical behaviors in bilingual and structured English-immersion programs serving Spanish-speaking English language learners in a large urban school district in Southeast Texas. The two programs included both intervention/control of each type during…

Teaching is a complex endeavour that requires teachers to meld knowledge about the nature of learners, pedagogical strategies and discipline content. In recent years an increasing variety of educational technologies are finding their way into the school classroom, including the widespread acceptance of interactive whiteboards (IWBs). The emerging…

This investigation examined the effectiveness of teaching letter sounds in a small group arrangement using computer-assisted instruction with SMART Board technology and a 3s constant time delay procedure to three students with learning disabilities. A multiple probe design across letter sound sets and replicated across students evaluate the…

The author demonstrates how simple snapshots can open new entryways into literacy for all children and help educators view teaching and learning in new ways, building classroom-wide and school-wide community. The book offers projects that help children see real-world possibilities in literate behaviors by using photos as a stimulus for literacy…

For nearly twenty years the educational community has utilized portfolios as a method of monitoring the growth and development of candidates earning certification as educators and as school leaders. Professors in the field of education have encouraged their students to share these portfolios with public school hiring officials. There is a belief…

PowerPoint and other visual technologies have become pervasive in schools. Adoption of these technologies is perceived as a necessary--or, at the very least, an educationally appropriate--innovation in UK schools, even though systematic examination of their use is relatively recent. On the basis of a wider ethnographic study of ICT use in one UK…
