This paper proposes a model for a general interface between people and Computer Algebra Systems (CAS). The main features in the CAS interface are data navigation and the possibility of accessing powerful remote machines. This model is based on the idea of session management, in which the main engine of the tool enables interactions with the…

This paper presents aspects of modeling, authoring, and presenting structured documents corresponding to teaching material presented in the World Wide Web. In this context, the importance of providing the formalization of the structure of the documents using Standard Generalized Markup Language (SGML) is discussed. Next, specifications for…

This document is the 27th report in a series begun in 1964. It provides revisions to projections shown in "Projections of Education Statistics to 2007" and includes statistics on elementary and secondary schools and institutions of higher education at the national level. Included are projections for enrollment, graduates, classroom…

In August, 1997, Gavilan College (Gilroy, California) was awarded a Fund for Instructional Improvement grant to review the current and projected roles of information competency instruction within California community colleges and to develop an information competency draft plan for system implementation, training, and evaluation. Five day-long…

This monograph reviews the research in linkages between schools and families of children with disabilities. An introductory section offers vignettes showing a typical school/home relationship of a family with a Down syndrome child in either 1958, 1978, or 1998. Part 1 considers what research has found about family functioning in terms of the…

An integrating framework to explain the research process was presented in the first edition of this book. This edition, which brings the material up to date, is designed to serve the Master s level student better while still meeting the needs of doctoral students of educational research. The nature of research, methods for qualitative and…

This document contains three papers from a symposium on changing organizational forms. "Goal Integration in a Multi-divisional Organization" (Richard J. Torraco, Mary Finnegan), reports on a study that examined how goals are integrated into organizational activities once they have been identified, proposes a model of goal integration,…

This paper describes a range of computer assisted learning software models--linear, unstructured, and ideal--and discusses issues such as control, interactivity, and ease-of-programming. It also introduces a "compromise model" used for a package currently under development at the Hong Kong Polytechnic University, which is intended to…

Since 1993, the Critical Thinking Cooperative (TC2) has initiated projects with school districts and universities throughout British Columbia. To date, the main emphasis has been on social studies, with the exception of some recent work in language arts. This paper investigates the application of the TC2 model of critical thinking to computers,…

This paper presents an approach for developing flexible Hypermedia Learning Environments (HMLE) and applies this theoretical framework to the creation of a layered model of a hypermedia system, called HyperDisc, developed at the German Institute for Research on Distance Education. The first section introduces HMLE and suggests that existing…

This guide is the result of an Ohio task force which reviewed issues related to the identification, evaluation, and provision of appropriate educational services to children with language impairments. Two question and answer pages direct readers to the relevant sections of this guide. The first section, on the nature of language, looks at the…

This paper discusses portfolios as an evaluative process in teacher education, noting that although there has been significant curriculum change over the years, yet little change has occurred in student evaluation methods. For schools to demonstrate improvement, new and creative evaluation measures are needed. Portfolios provide a chance to create…

A comprehensive teacher demand, supply, and shortage (TDSS) model is proposed as a conceptual framework for analyzing and determining the teaching force in bilingual and English-as-a-Second-Language (ESL) education. Available data on the shortage of bilingual education teachers are reviewed, and new national data on their characteristics are…

These five issues of "Research in Developmental Education," examine the theoretical models and foundations of developmental education. Included are the following: (1) "Theoretical Foundations of Developmental Education," by Hunter R. Boylan, which examines the behaviorist, humanist, and developmental theories underpinning developmental education;…

Issues related to between-class and within-class decomposition of achievement variance and the change of this decomposition over the course of the eighth-grade were examined using the Second International Mathematics Study (SIMS, 1985), a study in which there was a nested or hierarchical data structure of students within classes, within schools,…
