The use of Mixed Methods (MM) in evaluation has increasingly become a valuable asset in evaluators' methodological toolbox. Despite prolific research on various aspects of mixed methods, from typologies to ontological debates, there remains a dearth of empirically derived evidence on effectively communicating MM findings. This lack of empirical…

High-quality mentoring relationships help college students to achieve their academic potential and career goals. However, less is known about factors that shape the antecedents of mentoring relationships (e.g. mentor-protégé psychological similarity), or the impact of similarities on the development of high-quality mentoring relationships. The…

Single-case comparative studies could help identify efficient instructional procedures for individuals with disabilities. However, previous literature reported inconsistent efficiency results if multiple comparisons were conducted, indicating that within-participant replication was uncommon. In this review, we examined single-case comparative…

More aggregate data on school performance is available than ever before, opening up new possibilities for applied researchers interested in assessing the effectiveness of school-level interventions quickly and at a relatively low cost by implementing comparative interrupted times series (CITS) designs. We examine the extent to which effect…

This study represents a large meta-analytic investigation of character education studies. We identified 214 studies up until 2017 (N[subscript Total] = 307,512) with at least one computable effect size comparing a character education program to a control condition. Initial analyses indicated a small, significant average positive effect for…

Youth-led participatory action research (YPAR) is a theoretical-methodological approach that has been designed to promote positive development (e.g., well-being and health, social-emotional and cognitive development, academic or career advancement) and civic engagement among young people. Although YPAR holds particular promise, there has been…

In-person tutoring has been shown to improve academic achievement. Though less well-researched, virtual tutoring has also shown a positive effect on achievement but has only been studied in grade five or above. We present findings from the first randomized controlled trial of virtual tutoring for young children (grades K-2). Students were assigned…

Previous meta-analyses on peer tutoring have mainly included studies using treatment-control/comparison design and excluded studies that adopted pre-test-post-test design. However, some recent meta-analyses on other interventions adopting pre-test-post-test design revealed that certain crucial intervention moderators should be considered when…

We describe a combination of methods for assessing the effectiveness of complex interventions, especially where substantial heterogeneity with regard to the population, intervention, comparison, outcomes, and study design of interest is expected. We applied these methods in a recent systematic review of the effectiveness of reinforced home-based…

Given the widespread use of non-experimental (NE) methods for assessing program impacts, there is a strong need to know whether NE approaches yield causally valid results in field settings. In within-study comparison (WSC) designs, the researcher compares treatment effects from an NE with those obtained from a randomized experiment that shares the…

As internationalization initiatives on university campuses have increased in the past decade, the practice of mentoring diverse scholars has increased. In an exploratory study conducted at a doctoral/research-extensive university in the Midwest, researchers investigated the nature and functions of mentoring and the role of mentoring networks in…

In this study, researchers at a large, urban, comprehensive minority-serving institution used propensity score matching to identify a unique comparison group to study academic and graduate school outcomes in students served by the National Institutes of Health-funded Building Infrastructure Leading to Diversity (BUILD) Initiative. Acknowledging…

Tools for evaluating the quality and rigor of single case research designs (SCD) are often used when conducting SCD syntheses. Preferred components include evaluations of design features related to the internal validity of SCD to obtain quality and/or rigor ratings. Three tools for evaluating the quality and rigor of SCD (Council for Exceptional…

The phenomenon of low fertility has been negatively impacted on the social structure of the educational environment in Taiwan. To increase the learning effectiveness of students became the most important issue for the Universities in Taiwan. Due to the subjective judgment of evaluators and the attributes of influenced factors are always fuzzy, it…

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…
