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.…

In the past few decades, we have seen a rapid proliferation in the use of quasi-experimental research designs in education research. This trend, stemming in part from the "credibility revolution" in the social sciences, particularly economics, is notable along with the increasing use of randomized controlled trials in the strive toward…

Background: Current policy discourses emphasise the importance of evidence in education, including evidencing the impact of teacher professional learning on student outcomes. Randomised controlled trial (RCT) designs are promoted to measure 'impact'. Recent debates about this reflect longer standing methodological disputes. Advocates of…

In this paper, we analyse the impact of teacher participation in a University Teaching Diploma on student approaches to studying and learning experience. A quasi-experimental and multilevel design was employed. University teachers answered the Approaches to Teaching Inventory and students completed the Course Experience Questionnaire and the Study…

Background: Pre-service training of treatment parents is a requirement for all foster care models to ensure safety and well-being of children in care. Researchers theorize treatment parents benefit more from enhanced pre-service trainings; however, no rigorous studies exist indicating the effectiveness of these trainings for treatment parents.…

This study considers the impact of using a series of Mindset interventions during a five-day outdoor personal development (OPD) course. Self-efficacy, resilience and Mindset were measured pre course, post course and one month post course. It was hypothesised that both experimental and control groups would increase their self-efficacy and…

Science is being criticized within scientific domains and society. To address this, we suggest that researchers in special education, broadly, and those working in the behavioral disorders field, specifically, consider three critical facets of research: (a) importance of rigor, (b) value of replication, and (c) transparency of reproducibility in…

Background: African American women have the highest risk of death from heart disease among all racial, ethnic, and gender groups due to sedentary behaviors. Purpose: This article describes an intervention among 2 groups--a program group and an information group (intervention and comparison)--that assessed cardiovascular risk factor knowledge among…

I review the research literature on parent satisfaction with private school choice programs providing vouchers, scholarships, or education savings accounts. The reviewed studies make use of parent surveys to measure satisfaction, often comparing the responses of parents of scholarship lottery winners to those of parents of students who lost…

Children with a diagnosis of autism are more likely to experience anxiety than their typically developing peers. Research suggests that Cognitive Behavioural Therapy (CBT) could offer a way to help children with autism manage their anxiety but most evidence is based on clinical trials. This study investigated a school-based CBT programme using a…

High pedagogical quality in early childhood education and care (ECEC) is related to developmental outcomes in young children. This review summarizes findings from (quasi)-experimental studies that evaluated in-service training effects for ECEC professionals on external quality ratings and child development. The aggregation of findings at teacher…

Background: Previous studies of urban school-based health centers (SBHCs) have shown that SBHCs decrease emergency department (ED) utilization. This study seeks to evaluate the effect of SBHCs on ED utilization in a rural setting. Methods: This retrospective, controlled, quasi-experimental study used an ED patient data set from the Bassett…

This quasi-experimental study examined the potential benefits of zero-error dictation, a teaching technique based on dialogue-driven dictation, and the extent to which target linguistic features and proficiency levels mediated its effects on second language (L2) learners' accurate use of French grammatical morphology. Seventy-nine learners of L2…

Intervention against cyberbullying and other risks associated with the misuse of ITC and social networks is an important social demand. The 'Asegúrate' Program tries to support teachers in this intervention. This research shows the impact of the program among those that have shown to be less sensitive in other studies: cyber-aggressors.…

This paper reports research that engaged in the evaluation of an intervention programme designed to enhance the employability of a group of unemployed graduates. The evaluation adopted a quasi-experimental intervention research method employing a general self-efficacy scale, which had been validated in prior research. Results revealed that…
