In this article, the author discusses the use in policy analysis of models that incorporate uncertainty. He believes that all models should consider incorporating uncertainty, but that at the same time it is important to understand that sampling variability is not usually the dominant driver of uncertainty in policy analyses. He also argues that…

Two studies were carried out to evaluate the quality of multidimensional item response theory (MIRT) model parameter estimates obtained from the computer program NOHARM. The purpose of the first study was to compute empirical estimates of the standard errors of the parameters. In addition, the parameter estimates were evaluated for bias and the…

What is meant when people say that "learning environments are increasingly complex"? What is known about the cognitive processing that occurs during complex learning? How can educators provide effective instructional support for students who must learn and apply complex knowledge? These questions, and related issues, have fascinated educators and…

Describes study that determined differences between Masters of Business Administration (MBA) students and Bachelors of Business Administration (BBA) students through the use of a computerized management simulation. Performance, behavioral, and attitudinal measures are described, hypotheses tested are outlined, variables are explained, and results…

Two experiments assessed whether children's difficulty with word problems can be attributed to difficulty in comprehending abstract or ambiguous language. The subjects were 38 first-, 36 second-, and 36 third-graders. The resulting theory of arithmetic word problem solving may represent a theoretical problem-solving model. (TJH)

The relationship between intellectual ability, working method, and learning was investigated with simulations in both structured and unstructured learning environments. High- and low-intelligence college students' thinking-aloud protocols were analyzed on quality of working method. Results indicated that both intellectual ability and working…

Guidelines for developing performance assessments in science education allied with current research and reform are presented. The guidelines are applied to 3 hands-on science investigations performed by over 300 fifth and sixth graders and scored by science educators. Although difficult to develop, such assessments can be scored reliably. (SLD)

This article describes the use of a management simulation in a Chinese university during the spring semesters of 1997, 1998, and 2000. Although administrative difficulties presented special problems, Chinese university administrators were interested in introducing this form of experiential learning. Student reaction was positive. Participating in…

This issue of the journal contains abstracts and critical comments for 13 published reports of research in mathematics education. Topics include: (1) effects of mathematics anxiety on preservice elementary teachers; (2) visualizing rectangular solids; (3) computer simulations and abstract thinking; (4) the association of foldout shapes with…

Information and Communications Technology (ICT) plays a dominant role in enhancing teaching and learning. Similar advances have been made in the use of multimedia in the classroom. These advances are coupled with newer developmental tools and techniques. This paper examines the design and development of a simulation on water conservation. Science…

In 2005 an existing undergraduate course in project management was converted from face-to-face mode to wholly online mode. Wholly online mode means that there are no face-to-face classes at all, and all teaching and learning is facilitated through an online environment. The revised project management course was designed with an underlying…

This publication presents the following articles: (1) Advanced Technological Education (ATE) Develops Student Recruitment and Retention Strategies; (2) Marketer Advises Tech Educators Appeal to Teens' Emotions, Desires to Do Something Important; (3) Digital Bridge Academy Gets At-Risk Students on Paths to Knowledge-Based Careers; (4) Project…

From 1960 to 1980, school enrollment and educational expenditures in developing countries experienced significant expansion. By the late 1980s, however, this trend had slowed. This report examines the impact of education upon welfare and productivity. A unified global data set is used to address the question from a macroeconomic, gender-specific,…

Chapter One of the Education Consolidation and Improvement Act (ECIA) distributes compensatory education grants on the basis of a formula that considers population and cost factors for each of the nation's 3,128 counties. The focus of this report is the effectiveness of that formula in meeting the stated purpose of the legislation to provide aid…
