This paper examines the scalability of the results from the Tennessee Student-Teacher Achievement Ratio (STAR) Project, a prominent educational experiment. We explore how the misalignment between the experimental design and the econometric model affects researchers' ability to learn about the intervention's scalability. We document heterogeneity…

A randomized experiment that measures the impact of a social policy in a sample of the population reveals whether the policy will work on average with universal application. An experiment that includes only the subset of the population that volunteers for the intervention generates narrower "proof-of-concept" evidence of whether the…

In paired experiments, participants are grouped into pairs with similar characteristics, and one observation from each pair is randomly assigned to treatment. The resulting treatment and control groups should be well-balanced; however, there may still be small chance imbalances. Building on work for completely randomized experiments, we propose a…

The major aim of this manuscript is to bring together two important topics that have recently received much attention in child and adolescent research, albeit separately from each other: single-case experimental designs and statistical mediation analysis. Single-case experimental designs (SCEDs) are increasingly recognized as a valuable…

These are the appendices for the report "Study of College Transition Messaging in GEAR UP: Impacts on Enrolling and Staying in College." Five appendices are included in the document: (1) Additional Details about College Transition Messaging; (2) Additional Information about How the Study Was Designed and Implemented; (3) Supplemental…

This meta-analysis provides an extensive and organized summary of intervention studies in education that are grounded in motivation theory. We identified 74 published and unpublished papers that experimentally manipulated an independent variable and measured an authentic educational outcome within an ecologically valid educational context. Our…

The purpose of this study was to determine if the successful completion of a course designed to enhance student success increased the likelihood of students persisting from term-to-term at Ivy Tech Community College Southern Indiana, and whether there was a significant difference in student retention (as determined by persisting to the next term)…

The study explored the relationship between global software development teams, effective software requirements, and stakeholders' perception of successful software development projects within the field of information technology management. It examined the critical relationship between Global Software Development (GSD) teams creating effective…

Varying methods for evaluating the outcomes of single case research designs (SCD) are currently used in reviews and meta-analyses of interventions. Quantitative effect size measures are often presented alongside visual analysis conclusions. Six measures across two classes--overlap measures (percentage non-overlapping data, improvement rate…

The organisers of the 2012 London Olympics have endeavoured explicitly to use the Games to inspire a generation. This is nothing short of putting the main claim of Olympism to the test, but surprisingly the Inspire project has received virtually no scholarly scrutiny. Using an educationally-informed view of inspiration, this paper interrogates the…

Education has proven to be an effective means of developing the human resource base of most nations and could advance the development of nations. In other to upgrade and train more professionals and non-professionals in the sphere of education, the concept of teacher distance education has gained more attention globally. Therefore, more and new…

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…

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…

Objective: The purpose of this study was to determine which type of prevention message (abstinence, social norms, or responsible drinking) was most effective at reducing alcohol consumption. Participants: The subjects from this study included 194 college students from a public university. Methods: Researchers employed a quasi-experimental design,…

This quasi-experimental post-test only control group designed quantitative study examined whether or not members of an experimental group of participants who utilized two metacognitive strategy training regimens experienced a significant increase in their ACT mathematics sub-test scores compared to a group of students who did not utilize either of…
