Measurement of clinically significant change is critical for rehabilitation research because it can enhance the credibility of rehabilitation efforts and guide evidence-based practices. The practical appeal of clinically significant change is that it can bridge research and clinical practice by focusing on individual rather than group differences.…

Within the context of a counterbalanced design, 102 students from either a high school or a large Southeastern university were administered two versions of the Minnesota Multiphasic Personality Inventory-Adolescent (MMPI-A): a computer-administered version (CA) and a paper-and-pencil version (PAP). Time between testing sessions was approximately…

First Amendment principles are fragile, unless they have widespread public support. People form lasting views about civil liberties and other political issues in adolescence. They are influenced by many factors, including what they learn and experience in schools. Therefore, schools' treatment of the Constitution and the press is important for the…

The Environmental Inquiry program supports inquiry based, student-centered science teaching on selected topics in the environmental sciences. Many teachers are unfamiliar with both the underlying science of toxicology, and the process and importance of peer review in scientific method. The protocol and peer review process was tested with college…

This study systematically analyzed social and cognitive processes that underlie the development of argumentative knowledge. Group discussions of controversial issues and explicit instruction in argumentation were expected to help students acquire a sense of the overall structure of an argument, or an argument schema. In a quasi-experiment, 128…

This article examines the relationship between the use of online tutoring sessions and student success in developmental writing courses. The results suggest a statistically significant difference between the success rates, as measured by course grades, of those students who use the tutoring service and those who do not, thus suggesting the…

Purpose: The purpose of this study was to review research published by Educational Administration Quarterly (EAQ) during the past 10 years to determine if confidence intervals and effect sizes were being reported as recommended by the American Psychological Association (APA) Publication Manual. Research Design: The author examined 49 volumes of…

Purpose: This study examined 2nd-grade teachers' perceptions of the academic, social, and behavioral competence of students with speech sound disorders (SSDs). Method: Forty-eight 2nd-grade teachers listened to 2 groups of sentences differing by intelligibility and pitch but spoken by a single 2nd grader. For each sentence group, teachers rated…

e-Learning, of late, has been witnessing an unprecedented expansion as an opportunity for higher education. This expanding alternative mode calls for ensuring and imparting a sound and qualitative education. The present study made an attempt to investigate the issues related to the quality dimensions of e-learning. Our results revealed the…

In this study, the authors examined the relationship of 1,128 sixth and seventh grade students' grades in four subject areas (i.e., math, reading, science, and social studies) and their scores on the Texas Assessment of Knowledge & Skills (TAKS) Reading, Math, and Writing measures for the 2006-2007 school year as a function of their weight…

Medical schools have reduced the time allotted to anatomy instruction. Consequently, schools engage students in more independent settings using information and communication technologies (ICT). There has been limited research in the use of video aids, a type of ICT, to enhance anatomy examination performance. The objective of this study is to…

Using data from the 2003 Baccalaureate and Beyond Longitudinal Study (B&B:93/03), this report profiles 1992-93 bachelor's degree recipients' experience with K-12 teaching in the subsequent 10 years, as well as their preparation for teaching. The analysis first compares current and former teachers in this cohort on several demographic and…

A study was undertaken at the College of the Canyons, in California, to assess the variation of grades given by mathematics instructors teaching intermediate algebra. A sample was drawn from all instructors who taught Math 070 repeatedly from fall 1990 to fall 1994, resulting in the examination of the grades of at least 200 students from classes…

Often, all of the variables in a model are latent, random, or subject to measurement error, or there is not an obvious dependent variable. When any of these conditions exist, an appropriate method for estimating the linear relationships among the variables is Least Principal Components Analysis. Least Principal Components are robust, consistent,…

The development and evaluation of methods for detecting potentially biased items or differentially functioning items (DIF) represent a critical area of research for psychometricians because of the negative impact of biased items on test validity. A summary is provided of the authors' 12 years of research at the University of Massachusetts…
