The objective of this research study was to explore the connection between teacher practice and their perceptions of self-efficacy in teaching. Two research questions were developed: Does employing Hattie's meta-analysis of the effect size of clarity, meaningful feedback, and discussion result in increased feelings of self-efficacy in teachers?…

Racism primarily has been examined in United States (U.S.) educational contexts via survey and qualitative investigations, which reveal Black, Indigenous, and People of Colors' (BIPOCs') self-reported experiences of individual racism. Missing from this research is a focus on the perpetrators of racism and the institutional nature of racism in U.S.…

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…

The topic of praise and more specifically, behavior-specific praise, in special education is complex. It requires an investigation of multiple types of praise in a variety of settings and a variety of individuals with even more severe intellectual and developmental disabilities and other impairments (IDDI). Historically, in much research,…

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…

This study explored the various types of suicide prevention gatekeeper training programs implemented on college campuses through a meta-analytic review. One hundred eighty-four effect sizes were calculated from 53 studies to explore seven outcomes of interest: (1) Knowledge of Suicide, (2) Knowledge of Gatekeeper Skills (GK), (3) Appropriateness,…

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…

A quantitative meta-analysis research study was undertaken to analyze literature on teacher perceptions regarding the use of technology integration from 2002 to 2012. During this time period, technology applications were developing at a fast pace and skills in technology use were increasingly required in the workplace. In response, schools began…

Attention-Deficit/Hyperactivity Disorder (ADHD) is a neurodevelopmental disability characterized by symptoms of inattention, hyperactivity and impulsiveness, which may cause impairment in a variety of cognitive, social, behavioral, and emotional domains. Extensive research has been conducted to determine the best course of treatment for…

In contrast to Early Intensive Behavioral Intervention (EIBI), there are far fewer meta-analyses evaluating Naturalistic Developmental Behavioral Interventions (NDBIs) (Schreibman et al., 2015). Indeed, Pivotal Response Treatment (PRT)--a prominent NDBI--lacks meta-analytic studies. In the context of developing a line of research on the…

This meta-analysis synthesized the findings from 23 published and five unpublished experimental or quasi-experimental group design studies on word problem-solving instruction for K-12 students with learning disabilities (LD) and mathematics difficulties (MD). A secondary purpose of this meta-analysis was to analyze the relation between treatment…

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…

The objective of this research was to conduct a meta-analysis to examine existing research studies on video modeling as an effective teaching tool for children and adolescents diagnosed with Autism Spectrum Disorder (ASD). Study eligibility criteria included (a) single case research design using multiple baselines, alternating treatment designs,…

The main purpose of this research was to survey the literature about the U.S. education system and synthesize the important conclusions that could be identified as the main features of the education system in general as they relate to student achievement. The criteria were set and the meta-analysis procedures were carefully followed. This process…

This series of meta-analyses investigates the effects of social interdependence (cooperative, competitive, and individualistic learning structures) on achievement and peer relationships among college students. This study quantitatively synthesized the literature on the effects of social interdependence on achievement and peer relationship outcomes…
