In this study the effects of the use of digital student monitoring tools for teachers (DMTs) on student achievement (primary and secondary schools, mathematics, reading, and language) were investigated through a meta-analysis (n = 14). The studies were also coded for feedback and intervention features, which resulted in three groups of…

Over the past decade, meta-analyses have been conducted to evaluate the impact of embodied pedagogical agents on learning outcomes. Most review studies have evaluated learning outcomes from the perspective of testing labels such as transfer, retention, recognition, free recall, and various other classifications. This is problematic, because…

Many statistical methods (estimators) are available for estimating the consensus value (or average effect) and heterogeneity variance in interlaboratory studies or meta-analyses. These estimators are all valid because they are developed from or supported by certain statistical principles. However, no estimator can be perfect and must have error or…

Making metamemory judgments reactively changes item memory itself. Here we report the first investigation of reactive influences of making judgments of learning (JOLs) on interitem relational memory--specifically, temporal (serial) order memory. Experiment 1 found that making JOLs impaired order reconstruction. Experiment 2 observed minimal…

School psychologists can play an important advocacy role in ensuring the latest evidence-based practices for students presenting with symptoms of attention deficit hyperactivity disorder (ADHD) are being implemented in their districts. ADHD is a highly stigmatized disorder due to a number of misconceptions (e.g., the prevalence of ADHD has…

This mixed methods study investigates the research on strategies for distance learning to identify best practices for distance teaching of secondary students. For this study, distance learning was defined as an organized educational experience that takes place either synchronously or asynchronously while the student is in a different physical…

The three studies included in this dissertation collectively aim to highlight the negative impact that culturally homogenous academic, social, and financial systems on college campuses have on the experiences of culturally diverse college students. Currently the academic, social, and financial experiences of college students are not structured to…

The instructor's eye gaze can serve as an important social cue in video lectures. The current study used two sets of three-level meta-analyses to explore the effects of the instructor's guided gaze or the instructor's direct gaze on learning outcomes, fixation time, perception of parasocial interaction, and cognitive load. A total of eight…

Previous research found bias in the estimate of the overall fixed effects and variance components using multilevel meta-analyses of standardized single-case data. Therefore, we evaluate two adjustments in an attempt to reduce the bias and improve the statistical properties of the parameter estimates. The results confirm the existence of bias when…

Since its inception in 1949, over 1,500 studies have investigated the validity of the GRE General Test to predict its performance criteria in higher education (Klieger, Bridgeman, Tannenbaum, & Cline, 2016). The present review paper sought to examine the predictive validity of the GRE General Test. Factors affecting the predictive validity…

The conventional Q statistic, using estimated inverse-variance (IV) weights, underlies a variety of problems in random-effects meta-analysis. In previous work on standardized mean difference and log-odds-ratio, we found superior performance with an estimator of the overall effect whose weights use only group-level sample sizes. The Q statistic…

There exists a variety of interval estimators for the overall treatment effect in a random-effects meta-analysis. A recent literature review summarizing existing methods suggested that in most situations, the Hartung-Knapp/Sidik-Jonkman (HKSJ) method was preferable. However, a quantitative comparison of those methods in a common simulation study…

This systematic review and meta-analysis explores the impact of motivational reading interventions on the reading achievement and reading motivation of school-age students. Results of preliminary searches for--and inspection of--the existing meta-analytic literature suggest that while there exist published meta-analyses on motivational reading…

Selective publication and reporting in individual papers compromise the scientific record, but are meta-analyses as compromised as their constituent studies? We systematically sampled 63 meta-analyses (each comprising at least 40 studies) in "PLoS One," top medical journals, top psychology journals, and Metalab, an online, open-data…

This study explores the performance of classical methods for detecting publication bias--namely, Egger's regression test, Funnel Plot test, Begg's Rank Correlation and Trim and Fill method--in meta-analysis of studies that report multiple effects. Publication bias, outcome reporting bias, and a combination of these were generated. Egger's…
