Discusses the adaptive compression of computer files of numerical data whose statistical properties are not given in advance. A new lossless coding method for this purpose, which utilizes Adelson-Velskii and Landis (AVL) trees, is proposed. The method is effective to any word length. Its application to the lossless compression of gray-scale images…

Offers new sibling constellation coding method (Base 32) for genograms using binary and base 32 numbers that saves considerable microcomputer memory. Points out that new method will result in greater ability to store and analyze larger amounts of family data. (Author/CM)

Assessed the effects of postorganization activities on the acquisition of information presented in a knowledge-map format. Results from two experiments involving 145 college students suggest that postorganization activities that emphasize spatial encoding enhance the effectiveness of knowledge maps, especially with respect to superordinate…

Explores current methods for deploying EAD (Encoded Archival Description) electronic finding aids to identify the most promising practices being used, examines types of evaluation archivists are gathering from end-users regarding deployment methods, and identifies archivists' perceptions regarding the use of EAD-encoded finding aids based on an…

Provides an overview of content analysis, a powerful data reduction technique. It is a systematic, replicable technique for compressing many words of text into fewer content categories based on explicit rules of coding. The technique extends far beyond simple word frequency counts, but requires careful definition of categories. (SLD)

The objective of this study is to present "The Spiral Model for the Development of Coordination" (SMDC), a learning model that reflects the complexity and possibilities embodied in the learning of movement notation Eshkol-Wachman (EWMN), an Israeli invention. This model constituted the infrastructure for a comprehensive study that examined the…

The current research employs the use of content analysis to teach research methods concepts among students enrolled in an upper division research methods course. Students coded and analyzed Jimmy Buffett song lyrics rather than using a downloadable database or collecting survey data. Students' knowledge of content analysis concepts increased after…

The initiation of new accreditation standards for the Western Association of Schools and Colleges in 2002 mandated assessing student learning as a requirement for all community colleges. This study examined a non-Californian community college recognized by experts as having successfully institutionalized student learning outcomes. Qualitative data…

This article examines how the states plan to implement the Programs of Study (POS) that were mandated by the 2006 reauthorization of the federal legislation for career and technical education. A coding system was developed for summarizing the methods described in the plans of all 50 states, the District of Columbia, Guam, and the Virgin Islands.…

This paper reports on a mixed methods study of adolescents' responses to case material about social exclusion. First, a qualitative coding method is presented that describes the way adolescents choose and justify strategies to negotiate such situations. The responses were then analysed quantitatively using chi square tests and multinomial logistic…

In this article we describe the emerging area of text classification research focused on the problem of collaborative learning process analysis both from a broad perspective and more specifically in terms of a publicly available tool set called TagHelper tools. Analyzing the variety of pedagogically valuable facets of learners' interactions is a…

This research explores the process of asynchronous problem-solving-based discussion activities and aims to understand limitations likely to arise during learners' problem-solving discussions. The research has combined lag-sequential analysis and quantitative content analysis, and expects to use such analyzing methods to further understand the…

In a rural community there is a risk that readers will not find connections to their own lives, which may affect the pleasure gained from reading. The purpose of this qualitative study is to examine the use of literature in a small rural elementary school, focusing on how sociocultural factors affect how students connect to and access literature.…

The current study evaluated the use of a manualized social skills program, Superheroes Social Skills, to increase the use of prosocial behaviors and decrease the use of aggressive behaviors for children with externalizing behaviors. The training was implemented by a school psychologist in a pullout group with four children with high-incidence…

This comparative study examined discourse and opportunities for interaction in two mathematics education methods classes, one face-to-face and one synchronous, online. Due to the content taught in the course, this study also sought to determine prospective mathematics teachers' understanding of variability and the role of discourse in each…
