In order to determine whether expenditures for mental health could be reduced and quality improved, Congress mandated that the Department of Defense conduct a demonstration project utilizing a wraparound mental health service system for child and adolescent military dependents. A longitudinal quasiexperimental design was used to evaluate the…

The authors conduct an evaluation of a middle school-based treatment program for youth with ADHD during early stages of treatment development. The studies focus on interpreting outcome trends in preliminary data and identifying assessment issues that will be important to consider when conducting a clinical trial. Parent reports indicate that the…

The purpose of this research was to ascertain if there were any significant differences in the ability to read logos and to make the transition to reading logos in manuscript forms of kindergarten children who received direct instruction with environmental print, those who received indirect instruction, and those who received no instruction with…

Prior studies of juvenile drug courts have been constrained by small samples, inadequate comparison groups, or limited outcome measures. The authors report on a 3-year evaluation that examines the impact of juvenile drug court participation on recidivism and drug use. A quasi-experimental design is used to compare juveniles assigned to drug court…

This study aims at understanding how the use of different reading activities affects readers' comprehension of short stories. Forty-seven students with an advanced level of English proficiency participated in the study where a quasi-experimental research design was pursued. The experimental and control groups of students completed different sets…

To provide the first interstate quasi-experimental assessment on the power of content integration in building reading skills, the authors studied the effects on reading comprehension of GeoLiteracy--a K-8 package of 85 lessons that teaches geography in the context of practicing reading and writing skills. Ninety-six third through eighth grade…

Cooperative learning is in many ways a more effective learning method than individual and competitive learning. In this study, the effects of cooperative learning on the abilities of the preservice art teacher candidates to plan lessons were emphasized. For this purpose, 32 art teacher candidates were selected for the experimental group, and 32…

Orton-Gillingham (OG) and Orton-Gillingham-based reading instructional programs are commonly implemented reading programs in the United States. Twelve studies that employed quasi-experimental or experimental designs are reviewed. These studies included elementary students, adolescents, and college students. Of the 12 studies, 5 reported that the…

This article explores the effectiveness of writing to help nurse-learners develop critical thinking in an asynchronous, online learning environment. The formal written assignments of students in an online nursing health assessment program were analyzed for evidence of critical thinking according to Johns' Model of Structured Reflection (Johns,…

Evaluating the effects of interventions is among the most critical issues faced by the field of human resource development today. This study addresses the potential of multisource feedback for training evaluation. The central research question is whether or not it is possible to measure change in work behavior, as a result of training, with…

Simulations are widely viewed to be effective pedagogical tools; however, evidence concerning their effects on student learning has been largely anecdotal or unsystematic in nature. In addition, most of the literature focuses on fairly complex simulations that require more class time and demand more of students than may be possible in many…

The purpose of this study was to compare the results of an analysis of covariance design to a method developed by the authors called within-class regression. Application of this statistical method can be to any quasiexperimental design with a large number of groups. A test of statistical significance to use with the within-class regression…

A sample of 51 fourth graders' perceptions of the quality of their school life, including satisfaction with school, commitment to their classwork, and attitudes toward teachers was assessed at the beginning and end of the school year, as were beliefs concerning responsibility for successful, unsuccessful, and overall academic achievements. Results…

A solution to the problem of specification error due to excluded variables in statistical models of treatment effects in nonrandomized (nonequivalent) control group designs is presented. It involves longitudinal observation with at least two pretests. A maximum likelihood estimation program such as LISREL may provide reasonable estimates of…

Estimates of program effects from a compensatory preschool intervention were investigated using econometric simultaneous modeling, latent variable structured modeling, and ordinary least squares regression. Data for 806 black children indicated that different quasi-experimental estimation methods that attempt to control for selection bias can…
