Educational technology is the development, application and evaluation of systems, techniques and aids to improve the process of human learning. In almost all the important activities engaged in the name of teaching, training or instructions the possibility of using educational technology has been explored and is being explored, even today.…

The purpose of this qualitative study was to explore the influence a simulated virtual team learning experience had on business school students' leadership competencies. The researcher sought to discover the relationship between filling the leadership role in the simulated virtual environment and developing leadership competencies. A…

In light of a recent revelation that Gersten (1985) included erroneous information on one of two programs for English Language Learners (ELLs), the authors re-calculate results of their earlier meta-analysis of program effectiveness studies for ELLs in which Gersten's studies had behaved as outliers (Rolstad, Mahoney & Glass, 2005). The correction…

Presents a class of distortion controlled vector quantizers that are capable of compressing images so they comply with certain distortion requirements. Highlights include tree-structured vector quantizers; multiresolution vector quantization; error coding vector quantizer; error coding multiresolution algorithm; and Huffman coding of the quad-tree…

Reviews three theories of how we retain order in memory and their predictions for errors people make when they recall a sequence incorrectly. A new model of short-term memory is presented, the Start-End Model (SEM), in which the positions of items in a sequence are coded relative to the sequence start and end. (SLD)

In this study, we analyzed the quality of students' written scientific explanations found in notebooks and explored the link between the quality of the explanations and students' learning. We propose an approach to systematically analyzing and scoring the quality of students' explanations based on three components: claim, evidence to support it,…

The U.S. Department of Education's National Center for Education Statistics has updated the household and prison public-use data files for the 2003 National Assessment of Adult Literacy and the 1992 National Adult Literacy Survey. The accompanying 2003 National Assessment of Adult Literacy Public-Use Data File User's Guide explains how the data…

This article presents information on the development and validation of the Facial Expression Coding System (FACES; A. M. Kring & D. Sloan, 1991). Grounded in a dimensional model of emotion, FACES provides information on the valence (positive, negative) of facial expressive behavior. In 5 studies, reliability and validity data from 13 diverse…

A significant issue in primary teacher education is developing a knowledge base which prepares teachers to teach in a range of subject areas. In Australia, the problem in primary social science education is compounded by the integrated nature of the key learning area of Studies of Society and Environment (SOSE). Recent debates on teaching…

This article provides an analysis of student responses to an exercise used in a computer ethics and a software engineering course to raise awareness of issues related to hiring, including issues of professional responsibility and diversity. Students from two different universities were asked to evaluate four candidates for two positions in a…

Context: Decades of behavioral research suggest that awareness of health threats is a necessary precursor to engage in health promotion and disease prevention, findings that can be extended to the community level. Purpose: We sought to better understand local perspectives on the main health concerns of rural Appalachian communities in order to…

The prominent role of Boolean classes in qualitative data analysis software is viewed by some as an encroachment of logical positivism on qualitative research methodology. The authors articulate an embodiment perspective, in which Boolean classes are viewed as conceptual metaphors for apprehending and manipulating data, concepts, and categories in…

The study investigated at what age children draw boundaries around pairs of objects that share either similarity or proximity. In two studies (N=132 and N=252) using a Wertheimer array, a clear age trend between 4 and 8 years showed that while young children were more likely to code objects into individual regions, older children were more likely…

A general inductive approach for analysis of qualitative evaluation data is described. The purposes for using an inductive approach are to (a) condense raw textual data into a brief, summary format; (b) establish clear links between the evaluation or research objectives and the summary findings derived from the raw data; and (c) develop a…

In our recent paper, "Semantic generality, input frequency and the acquisition of syntax" ("Journal of Child Language" 31, 61-99), we presented data from two-year-old children to examine the question of whether the semantic generality of verbs contributed to their ease and stage of acquisition over and above the effects of their typically high…
