This paper introduces a simple, quotient effect size, termed (for 'quotient'), suitable for reporting on the effectiveness of educational interventions. The quotient effect size for a pre-test-post-test design is defined as the gain score (i.e. post-test minus pre-test) for the intervention group, divided by the gain score for the control group.…

Do quasi-experimental (QE) studies conducted with baseline covariates that are typically available in the longitudinal administrative state databases yield unbiased effect estimates? This paper conducts a within-study comparison (WSC) study that compares experimental impacts of early college high school (ECHS) attendance with QE impacts drawn from…

We consider situations in which public charter school lotteries are neither universally conducted nor consistently documented. Such lotteries produce "broken" Randomized Control Trials, but provide opportunities to assess the internal validity of quasi-experimental research designs. Here, we present the results of a statewide charter…

College professors have adopted numerous strategies for teaching undergraduates, yet few researchers provide empirical evidence students' learning actually increased because of the instructional innovation. Assessment of pedagogy is frequently subjective and based on comments from students or faculty. Consequently, evaluating the effectiveness of…

Relieving test anxiety actions range from relaxation exercises to prescription medication. Humor can be a simple method of test anxiety relief. The current study was used to determine if humor, in the form of a cartoon, placed on the splash page of an online exam improved the test scores of students who have high test anxiety. In the current…

The present study sought to evaluate the effects of a reading strategy instructional program on the reading competence of third-grade students. Students were instructed in fluent and strategic reading by trained research assistants in whole class settings and subsequently worked on expository text material together with peers. Their reading…

A quasi-experimental method and test-retest design were used to explore the impact of participating in test preparation, whether the impact of test preparation depends on the first ACT® score, and the impact of specific test preparation activities. Test preparation improved students' retest scores and this effect did not differ depending on…

The credibility of unsupervised exams, one of the biggest challenges of e-learning, is currently maintained by proctoring. However, little has been done to determine whether expensive and inconvenient proctoring is necessary. The purpose of this quantitative study was to determine whether the use of security mechanisms, based on the taxonomy of…

Bullying is a serious problem with long-term and short-term negative effects on both victims and perpetrators. Many bullying-prevention programs have been developed on the basis of peer support and social learning theories. The purpose of this study was to develop an antibullying program consisting of a short video and to survey the effectiveness…

With childhood obesity on the rise and the need for American children to be academically successful compared to peer nations, it is imperative that physical activity become part of the typical school day for all elementary aged school children. There is an understanding that physical activity not only benefits physical fitness and health, but that…

This article presents findings from a quasi-experimental evaluation of quality with a sample of 28 family child care providers in the All Our Kin Family Child Care Network, a staffed family child care network which offers a range of services including relationship-based intensive consultation, and 20 family child care providers who had no…

Registered Nurses use clinical documentation to describe care planning processes, measure quality outcomes, support reimbursement, and defend litigation. The Connecticut Department of Health, guided by federal Conditions of Participation, defines state-level healthcare policy to include required care planning processes. Nurses are educated in care…

Providing students with one-on-one interaction with instructors is a big challenge in large courses. One solution is to have students interact with their peers during class. Reciprocal peer tutoring (RPT) is a more involved interaction that requires peers to alternate the roles of "teacher" and "student." Theoretically,…

Metacognitive knowledge is a necessity in starting learning process. Solving physics problems requires metacognitive knowledge which comprises factual, conceptual and procedural knowledge. The purpose of metacognitive knowledge is to train students in developing their abilities in higher order of thinking. The problem is what kind of strategies…
