This report summarizes the complex research literature on quantitative methods for assessing how impacts of educational interventions on instructional practices and student learning differ across students, educators, and schools. It also provides technical guidance about the use and interpretation of these methods. The research topics addressed…

Essential for the validity of the judgments in a standard-setting study is that they follow the implicit task assumptions. In the Angoff method, judgments are assumed to be inversely related to the difficulty of the items; contrasting-groups judgments are assumed to be positively related to the ability of the students. In the present study,…

Both true experiments and regression discontinuity (RD) designs produce unbiased estimates of effects. However, true experiments are, of course, often criticized on equity grounds, whereas RD designs entail sacrifices in terms of statistical precision. In this article, a hybrid of true experiments and RD designs is considered. This hybrid entails…

Paulhus, Robins, Trzesniewski, and Tracy ("Multivariate Behavioral Research," 2004, 39, 305-328) suggested that the three types of two-predictor suppression situations--classical suppression, cooperative suppression, and net suppression--can all be considered special cases of mutual suppression, in that the magnitude of each of the two…

Despite the considerable research that has been conducted on issues of diversity on college campuses, there has been limited research addressing this issue on Hispanic Serving Institutions (HSIs). The present study investigated the predictors of Hispanic students' attitudes toward special efforts to recruit non-Hispanic students and faculty at an…

Eighty, seventh grade students attending a suburban middle school in southern Connecticut participated in the study evaluating the effectiveness of computer based geography games on student motivation and achievement. Using Connecticut Mastery Test (CMT) Scores and baseline U.S.A scores as criteria to develop matched pairs, students were divided…

This study is based on lecturers' and students' perception on educational policy implementation factors and quality education in Nigerian universities.

Much of the existing research in distance education has focused on contrasting the outcomes between traditional face-to-face teaching and purely online courses, in which the entire course content is delivered online. However, research has not examined the effectiveness of hybrid-online courses, in which a combination of online delivery and…

Background: In 2006, all local education agencies in the United States participating in federal school meal programs were required to establish school wellness policies. This study documented the strength and comprehensiveness of 1 state's written district policies using a coding tool, and tested whether these traits predicted school-level…

Electronic government has been embraced by many organizations seeking to dramatically improve service delivery, but results to date have often fallen short of expectations. This dissertation is focused on state revenue agencies and their electronic tax filing mechanisms for state individual income taxes. It asks: What factors best explain whether…

Sixth grade is a pivotal time in school, as students culminate their elementary school years and anticipate junior high school. At this age, students become more involved in trends, especially technological trends. When students can utilize the same type of technology inside and outside of school, their self-efficacy may increase. Hypothetically,…

The current study constitutes the first attempt to use a quasi-experimental method--the regression discontinuity (RD) design--to gauge the causal effect of dual enrollment (DE) on students' academic outcomes. Since dual enrollment can encompass a wide range of experiences, two separate analyses were performed. The first evaluates the impact of…

Developmental screening programs identify young children with delayed skill growth or challenging behaviors and refer them to community agencies for evaluation or other services. This research studied the predictive impact of developmental screening results and child and family characteristics on the completion of these referrals for evaluation. A…

This study examined students' movement in and out of special education and predictors for later special education placement. The sample ( N = 556) came from a response to intervention (RTI) study, specifically, a cluster-randomized control field trial that undertook the development and study of a hybrid Tier 1 (classroom instruction) and Tier 2…
