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.…

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…

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…

Elementary students spend an average of five and a quarter hours per day seated on a hard surface which provides little sensory input and possibly contributes to discomfort. Sensory integration was found to improve executive functioning skills in elementary students by helping their comfort level at being seated. This quasi-experimental study…

The purpose of this study was to investigate whether a growth intervention would improve adolescent special education students' self-efficacy and motivation. The research was conducted in a middle school in the Northeast from January 2016 to June 2016. The convenience sample for this study comprised of sixth, seventh, and eighth grade students…

Math skills are critical for children's future success in school, as school-entry math knowledge is the strongest predictor of later academic achievement. Although there is a recent increase of literature on math with young children, there is a scarcity of research related to young children with disabilities. This quasi-experimental study with 50…

Making causal inferences from a quasi-experiment is difficult. Sensitivity analysis approaches to address hidden selection bias thus have gained popularity. This study serves as an introduction to a simple but practical form of sensitivity analysis using Monte Carlo simulation procedures. We examine estimated treatment effects for a school-based…

A modified extensive reading literacy intervention was examined in this study. The problem was English Learner third and fourth-grade students reading standardized tests scores were low and educators were uncertain as to which type of intervention was best to improve English Learner student oral reading fluency and reading comprehension. This…

This article reports the results of a quasi-experimental study conducted to examine the efficacy of a new time management intervention designed for high school students. Participants were 149 students from a highly selective private high school in the northeastern United States who were in the ninth grade. Half of the students participated in a…

Purpose: Regression discontinuity (RD) design is a sophisticated quasi-experimental approach used for inferring causal relationships and estimating treatment effects. This paper aims to educate human resource development (HRD) researchers and practitioners on the implementation of RD design as an ethical alternative for making causal claims about…

This study investigated the effectiveness of Brainfeed intervention programme as an alternative approach for supporting people living with dyslexia. The study adopted a quasi-experimental research design. The population of this study is made up of twenty four thousand seven hundred and twenty seven (24,727) senior secondary school students (S.S.2)…

The effect of using tests in test preparation courses has been subject to debate. While some scholars such as Yang and Badger (2015) believe it is a cause of positive washback effect, others argue that this issue is tentative and context-bound (Green, 2007). Therefore, this study investigated the effect of using Mock tests in International English…

This article is intended to assist teachers and researchers in designing studies that examine the efficacy of a particular intervention or strategy with students with sensory disabilities. Ten research designs that can establish causal inference (the ability to attribute any effects to the intervention) with and without randomization are discussed.

Music psychologists have established that some forms of musical activity improve intellectual performance, spatial-temporal reasoning and other skills advantageous for learning. In this research, the potential of active music-making for improving pupils' achievement in spatial- temporal reasoning was investigated. As spatial-temporal skills are…

Several interventions aimed at increasing positive attitudes towards older adults among health-care professionals have been introduced. These interventions tend to focus on a small subset of clinical employees, ignoring other clinical and nonclinical hospital staff. The objective of this study was to evaluate the efficacy of a short aging…
