This exploratory study represents an analysis of 15 exit portfolios of students enrolled in a program to prepare teachers for urban schools. Portfolios were analyzed holistically across entries to determine the degree to which students integrated multiple concepts related to teaching in urban schools, including: asset/deficit perspectives,…

Over the past 25 years, meta-analysis has assumed a significant role in the synthesis of counseling and psychotherapy research through the evaluation and interpretation of the results of multiple studies. An examination of four widely recognized rehabilitation counseling journals, however, reveals that only one meta-analysis (Bolton & Akridge,…

Surprising downshifts from more preferred (training incentive) to less preferred incentives (test incentive) are usually accompanied by emotional activation and suppression of conditioned behavior in rats. Two experiments were designed to determine whether consummatory behavior is similarly affected by downshifts of equal proportions. Within…

This article presents a technique that will help teachers, researchers, and other people who use the linear regression models, especially those in education and social sciences, to understand and interpret the residuals graphics better.

In this article, a practical demonstration suitable for any biology college classroom is presented. With the examples of a complex biological specimen (slug's radula) and a simple reference specimen (electron microscopical grid imprint in gelatin), both of which can be easily prepared, the capabilities of two imaging modes commonly used in optical…

Mathematics and statistics play important roles in peoples' lives today. A day hardly passes that they are not bombarded with many different kinds of statistics. As consumers they see statistical information as they surf the web, watch television, listen to their satellite radios, or even read the nutrition facts panel on a cereal box in the…

People often make interpretations when they believe they are providing factual descriptions. To demonstrate unintentional interpretation, the author showed a brief ambiguous video clip and asked students to write descriptions of what they saw and heard. When students evaluated their responses, they discovered that 96% of the class wrote…

A long-standing issue in the study of how people acquire visual information centers around the scheduling and deployment of attentional resources: Is the process serial, or is it parallel? A substantial empirical effort has been dedicated to resolving this issue. However, the results remain largely inconclusive because the methodologies that have…

Chicago's Renaissance 2010 seeks to create 100 new and autonomous schools by 2010. These new schools are expected to increase choice for parents and students, enact innovative practices, and help create a portfolio of schools designed to make the Chicago Public Schools (CPS) more diversified, responsive, and effective. Renaissance Schools Fund…

Implementation of the No Child Left Behind (NCLB) legislation has been accompanied by demand for data systems capable of providing a longitudinal record of each student's educational experiences and performance over time. The national Study of Education Data Systems and Decision Making is examining both the implementation of student data systems…

Written by a social worker for social work students, this is a nuts and bolts guide to statistics that presents complex calculations and concepts in clear, easy-to-understand language. It includes numerous examples, data sets, and issues that students will encounter in social work practice. The first section introduces basic concepts and terms to…

School improvement without will and moral purpose--without a genuine commitment to all students--is an empty exercise in compliance that, in the authors' experience, can do more harm than good. The authors have seen educators use data to "more accurately" track students, further widening the opportunity-to-learn gap. In response to achievement…

An analysis of survey data is used to examine the practices used to hire teachers, the level of principal autonomy within the process, the attributes sought in teachers, and to compare each based upon the characteristics of schools and of principals. Findings indicate that urban and low-performing schools (and the principals of these schools) are…

The comparability of examinations in different subjects has been a controversial topic for many years and a number of criticisms have been made of statistical approaches to estimating the "difficulties" of achieving particular grades in different subjects. This paper argues that if comparability is understood in terms of a linking…

In the United States, when English language learners (ELLs) are tested, they are usually tested in English and their limited English proficiency is a potential cause of construct-irrelevant variance. When such irrelevancies affect test scores, inaccurate interpretations of ELLs' knowledge, skills, and abilities may occur. In this article, we…
