The presence of artifactual bias in analysis of covariance (ANCOVA) and in matching nonequivalent control group (NECG) designs was empirically investigated. The data set was obtained from a study of the effects of a television program on children from three day care centers in Mexico in which the subjects had been randomly selected within centers.…

The purpose of this study was to compare the achievement of students in 14 Pascagoula schools and 9 Biloxi schools implementing School Renaissance (SR) to that of students in matched control schools. The achievement measures to be examined were from the 2004 administration of the Mississippi Curriculum Test (MCT) for Reading, Language Arts, and…

A longitudinal quasi experiment tested the effects of a relapse prevention and transfer enhancement posttraining intervention on the self-efficacy, transfer behavior, and performance of a sample of nurses who attended a two-day training program on the McGill Model of Nursing. ANCOVA results failed to support the effectiveness of the intervention;…

The study evaluated the effectiveness of a community-based court intervention aimed at reducing truancy in a large urban school district. A quasi-experimental design was used to assess attendance outcomes for 567 truants matched on demographics and drawn from three categories of intervention (no court referral, traditional court referral, and…

Biology knowledge and understanding is important not only for the conversion of the loftiest dreams into reality for a better life of individuals but also for preparing secondary pupils for such fields as agriculture, medicine, biotechnology, and genetic engineering. But a recent study has revealed that many aspects of school science (biology…

Despite the preliminary studies that support solution-focused brief therapy, limited research has examined the model as a group intervention with students at risk for academic underachievement and school nonattendance. Therefore, the purpose of this study was to evaluate the impact of the model on school attendance and grade point average.…

The classroom teacher's comfort and familiarity with computers and software influences student-computer use in the classroom. Teachers remain mired in repetitive introduction of basic software mechanics and rarely progress with students to advanced concepts or complex applications. An Online Assistant (OLA) was developed to accompany the…

The "drop-out" of working-class students from universities has been identified as one of the most pressing issues for the higher education (HE) sector in the United Kingdom. This article draws on the initial findings of a major research project that explores the meanings and implications of such withdrawal from HE amongst young…

This study examined the reading gains of students with mild disabilities who were taught with one of two programs: "Horizons Fast Track A-B" (Engelmann, Engelmann, & Seitz-Davis, 1997) or "Reading Mastery Fast Cycle" (Engelmann & Bruner, 1995). A quasi-experimental design with preexisting groups was used to examine…

A two-stage procedure for the analysis of pretest-posttest data was developed and illustrated. Data were reanalyzed from a quasi-experimental evaluation that assessed the effects of an intervention program to teach elementary school children aged 10 to 12 years to watch violence on television more carefully/critically. The treatment group…

The implementation of research design in studies on substance abuse education is discussed in this meta-analysis. Findings indicate that the quality of research design is constrained by negative feedback from evaluation stakeholders. This finding is applied to an evaluation of the Here's Looking at You, 2000 drug education program currently…

This paper examines the social phenomenon of leadership succession in a school from the perspective of the successor, based on the author's own experience in succeeding to the principalship of a junior high school. Using a combination of participant observation, informal interview, and existing and collected documents, the study was designed to…

The effects of changes in spatial density on preschool children's behavior were examined in a quasi-experimental study involving repeated measures taken on two experimental groups and one control group. Subjects were all 59 children registered in three rooms of a non-profit public day care center in Edmonton, Alberta, Canada. Both quantitative and…

Reports the results of a quasi-experimental evaluation of the effects of the California English-only law on public librarians' acquisition policies and attitudes toward books in Spanish for children and young adults. The results, which showed no effects, are interpreted in terms of the symbolic functions of legislation and public policy. (seven…

Utilizes a quasiexperimental design to examine the impact of microcomputer simulations on environmental problem solving by community college students. The experimental group of students (n=34) showed a highly significant improvement in problem-solving skills after being exposed to three simulation models that focused on lake pollution analysis,…
