Semantic integrity constraints are business-specific rules that limit the permissible values in a database. For example, a university rule dictating that an "incomplete" grade cannot be changed to an A constrains the possible states of the database. To maintain database integrity, business rules should be identified in the course of database…

Synthesizing a decade of research, the author describes a taxonomy of meaningful learning. The most meaningful learning outcome is problem solving. In this taxonomy, four different kinds of problem solving are arranged in a hierarchical manner. Prerequisite/corequisite with problem-solving outcomes are two fundamental reasoning skills that…

Many children enjoy collecting items such as seashells, state quarters, and trading cards. Asking students to think about the ways in which similar items differ, how objects can be grouped by a common characteristic, and how groups can be subsets of a larger category leads to an understanding of fundamental mathematics and science concepts: sets,…

In this article, the author describes a short activity which introduces third- to fifth-grade students to animal classification. The Tree of Animal Life activity is a simple, sorting exercise that can help them see a bigger picture. The activity sets the stage for learning about animal taxonomy and introduces the characteristics of various animal…

One of the main professional-development challenges social studies teachers face involves adjusting content and instruction to accommodate the surging population of English Language Learners (ELLs). Between the 1993-1994 and 2004-2005 school years, ELL school populations increased 68 percent to more than 5.1 million, compared to a 7.8 percent…

Concerned that her students "knew" Spanish but could not use it in real life situations, the author created new learning goals, new learning activities, and new assessment activities. As a graduate student at the University of Illinois, the author was introduced to "Creating Significant Learning Experiences" (Fink, 2003) while studying with Steven…

One goal of the National Forum on Education Statistics is to improve the quality of education data gathered for use by policymakers and program decision-makers. One approach to furthering this goal has been to pool the collective experiences of Forum members to produce "best practice" guides in areas of high interest to those who…

This paper discusses various approaches to the phenomenon of disability in relation to special needs. Ever since disability researchers launched the social model of disability and criticised the field of special education for preserving an understanding of disability in accord with a medical model, the special education field has been in a state…

This article describes the development of a classification system to measure the expertise levels of practicing paediatric rehabilitation therapists. Seventy-five therapists from five disciplines (physical, occupational, speech-language, behaviour, and recreational therapy) were involved, along with 170 peers, and 188 parents of children with…

The Institute of Education Sciences (IES) and the What Works Clearinghouse (WWC) have identified topic areas that present a wide range of this nation's most pressing issues in education (e.g., middle school math, beginning reading, and character education). Within each selected topic area, the WWC collects studies of interventions (i.e., programs,…

This article describes a quizzing activity that aims to facilitate student cognitive engagement at a variety of Bloom's taxonomy levels and promote reading of course assignments. The quizzing activity described is potentially useful for any course. Because it is based on Bloom's cognitive taxonomy, which is itself designed to address the spectrum…

Since 1790, the US government has conducted a decennial census of the nation's population and its various ethno-racial subgroups. The official names for these subgroups have direct and significant consequences for the implementation and regulation of public policy at the national, state and local levels of governance. This paper first provides a…

Data suggest that students with emotional and behavioral disorders (EBD) are underidentified and underserved for a variety of reasons. In response to this problem, the authors identify misinformation and provide evidence-based information regarding prevalence; discuss the role of stigma and exclusion from the EBD category and appropriate responses…

This paper examines how the nature of the World Wide Web and characteristics of networked resources affect subject access and analyzes the requirements of effective indexing and retrieval tools. The current and potential uses of existing tools and possible courses of future development are explored in the context of recent research. The first…

The objective of this article is to develop baseline models showing principal approaches to category learning. All models are based on a common memory array but vary in memory access and decision processes useful for interpretation of empirical phenomena. The main models discussed are exemplar, prototype, and feature. (JAZ)
