This article uses data from the National Longitudinal Survey of Youth 1979-1998 to understand the differences between those who exited the welfare system voluntarily (leavers) and those who stayed (non-leavers), 1990-1996. The purpose of this research was to examine the differences between the groups in their personal and family characteristics,…

The purpose of this study was to investigate the effect of gender and grade level on students' logical thinking abilities. A total of 174 sixth, seventh, and eighth-grade students participated in the study. Test of Logical Thinking (TOLT) was administered to determine students' reasoning abilities. A two-way multivariate analysis of variance…

With growing numbers of drug-involved offenders, substance abuse treatment has become a critical part of corrections. A multistage therapeutic community implemented in the Delaware correctional system has as its centerpiece a residential treatment program during work release--the transition between prison and community. An evaluation of this…

Background: The development of youth psychopathology may be associated with direct and continuous contact with a different culture (acculturation) and to distress related to this process (cultural stress). We examine cultural experiences of Puerto Rican families in relation to youth psychiatric symptoms in two different contexts: one in which…

The National FFA Organization's Partners in Active Learning Support (PALS) is a program that utilizes high school members from FFA chapters as peer mentors. The purpose of this study was to examine needs of a sample of PALS advisors and mentors. An on-site pilot study was initially conducted, which included 3 individual interviews with program…

This paper reports a causal-comparative study of science anxiety among Form Four students in Penang. The Wynstra's (1991) Science Anxiety Inventory (SAI), which consists of six factors (i.e., danger anxiety, science test anxiety, math and problem-solving anxiety, squeamish anxiety, performance anxiety, and science classroom anxiety), was…

We examined how children with and without oral language (word-finding) difficulties (WFD) perform on oral reading (OR) versus silent reading recognition (SRR) tasks when reading the same words and how lexical factors influenced OR accuracy, error patterns, and nature of miscues. Primary-grade students were administered an experimental reading…

There is much research that documents what many teachers know, that students struggle with many concepts in probability and statistics. This article presents two sample activities the authors use to help preservice teachers develop ideas about how they can use technology to promote their students' ability to understand mathematics and connect…

This study investigates successful completion at a faith-based organization providing residential substance abuse treatment services. Method: The authors apply a complex systems paradigm using a single moderator variable. The participants are primarily African Americans and most have current criminal justice involvement. Probabilities of treatment…

Experiments that assign intact groups to treatment conditions are increasingly common in social research. In educational research, the groups assigned are often schools. The design of group-randomized experiments requires knowledge of the intraclass correlation structure to compute statistical power and sample sizes required to achieve adequate…

Background: The appropriateness of the "Diagnostic and Statistical Manual of Mental Disorders-Fourth Edition" (DSM-IV) nosology for classifying preschool mental health disturbances continues to be debated. To inform this debate, we investigate whether preschool psychopathology shows differentiation along diagnostically specific lines…

Background: Recent research in the USA and UK indicates that person-centred planning (PCP) can lead to improvements in lifestyle-related outcomes for people with intellectual disabilities (ID). It is clear, however, that the introduction of PCP does not have an equal impact for all participants. The aim of the present paper was to identify factors…

By using a competing risks model, survival analysis methods can be extended to predict which of several mutually exclusive outcomes students will choose based on predictor variables, thereby ascertaining if the profile of risk differs across groups. The paper begins with a brief introduction to logistic regression and some of the basic concepts of…

Research on factors related to student academic achievement typically involves the use of some type of total cognitive score as the final outcome measure. However, in using a total score, it is assumed that variables related to student learning have the same effect on student learning across academic skill levels. Using a subsample from the first…

Researchers should investigate statistical models that can help counselors decide how to treat individual clients. This research investigated the questions, "Given an effect size (ES) from a counseling outcome study, what is the probability that a client would have a negative response to the treatment, and what is the probability that the client…
