The purpose of the study was to demonstrate the effects of using high-quality feedback (HQF) to train educators on an ACT-based intervention called cognitive defusion. Since there was limited acquisition using HQF as a training method, the participants were switched to BST to learn the remaining cognitive defusion task. A delayed multiple probe…

This research study conducted a meta-analysis to integrate the studies that investigated the effectiveness of project-based learning on academic achievement based on a worldwide higher-education population. The researcher explored the variables that previous meta-analysis studies used to evaluate academic achievements, such as student grade point…

In randomized control trials (RCT), the recent focus has shifted to how an intervention yields positive results on its intended outcome. This aligns with the recent push of implementation science in healthcare (Bauer et al., 2015) but goes beyond this. RCTs have moved to evaluating the theoretical framing of the intervention as well as differing…

The purpose of this quantitative, meta-analysis was to discover what differences in effect size exist among strategies used in face-to-face settings and/or digital teaching and learning platforms to achieve communicative competence in foreign language learners. After strategies with the largest effect sizes were identified, results were…

In educational contexts, students often self-select into specific interventions (e.g., courses, majors, extracurricular programming). When students self-select into an intervention, systematic group differences may impact the validity of inferences made regarding the effect of the intervention. Propensity score methods are commonly used to reduce…

Classical statistical tests are used in many disciplines such as education and psychology. Such tests are based on certain assumptions (e.g., normality and homoscedasticity) that are must to be met in order to produce accurate results. Violation of such assumptions is a common problem researchers encounter, particularly when analyzing real data.…

This meta-analysis synthesized research on gender gap in the Force Concept Inventory (FCI). The main goal of the present meta-analysis was to identify the moderator variables that mediate effect size differences. Furthermore, the statistical significance of the average effect sizes was investigated. The inclusion criteria for the meta-analysis…

Integrating reading instruction and content area curriculum has been suggested as a method of improving students' reading comprehension and access to content knowledge. Less clear are the specific practices that should be used across the curriculum to improve comprehension and build knowledge simultaneously. The two studies in this dissertation…

A single case design was used to investigate the impact of two types of instruction on middle school students' spelling. Phase 1 emphasized morphology awareness instruction (MAI) and phase 2 employed the addition of prosody awareness instruction (PAI). In order to compare the effects of MAI and PAI, spelling scores were gathered from eight…

The research-to-practice gap in special education refers to educators' limited use of practices that are supported by empirical evidence. Procedures specifying criteria for the determination of evidence-based practices (EBPs) in special education have the potential to address challenges associated with identifying EBPs. Although meta-analyses and…

This study examines the impact of type of peer review first year college students participated in, either face-to-face (FSF) or online (OL) and its effect on students' writing achievement. Using a two-way repeated measures design, this research measured students' overall writing score as well as the five key areas of writing: focus and meaning;…

Often researchers face situations where comparative studies between two or more programs are necessary to make causal inferences for informed policy decision-making. Experimental designs employing randomization provide the strongest evidence for causal inferences. However, many pragmatic and ethical challenges may preclude the use of randomized…

For pediatric nurses, their competence in EBP is critical for providing high-quality care and maximizing patient outcomes. The purpose of this pilot study was to assess and refine a Web-based EBP educational intervention focused on improving EBP beliefs and competence in BSN-prepared pediatric bedside nurses, and to examine the feasibility,…

This paper serves two purposes. First, it statistically compares learning outcomes of face-to-face, online and blended learning instruction. Then it looks at the instructional practices that are associated with effective blended and online learning. A meta-analysis of 30 studies, with 3,687 participants, resulted in 36 effect sizes. The contrasts…

Research on the relationship between socioeconomic status and educational outcomes of students is abundant, but research related to factors that are capable of mediating the effects of poverty on the education of children is lacking. The purpose of this study is to provide a better understanding of such factors. A pilot study using The High School…
