This review describes a meta-analysis of findings from 50 controlled evaluations of intelligent computer tutoring systems. The median effect of intelligent tutoring in the 50 evaluations was to raise test scores 0.66 standard deviations over conventional levels, or from the 50th to the 75th percentile. However, the amount of improvement found in…

Human rights education (HRE) aims to achieve a change of mindsets and social attitudes that entails the construction of a culture of respect towards those values it teaches. Although HRE is a recent field of study, its consolidation in Latin America is a fact. During the latest decades several authors have carried out research related to HRE that…

When cluster randomized experiments are analyzed as if units were independent, test statistics for treatment effects can be anticonservative. Hedges proposed a correction for such tests by scaling them to control their Type I error rate. This article generalizes the Hedges correction from a posttest-only experimental design to more common designs…

The current study reports on a meta-analysis of the relative effectiveness of interaction in synchronous computer-mediated communication (SCMC) and face-to-face (FTF) contexts. The primary studies included in the analysis were journal articles and dissertations completed between 1990 and 2012 (k = 14). Results demonstrate that interaction in SCMC…

There are various educational methods used in anatomy teaching. While three dimensional (3D) visualization technologies are gaining ground due to their ever-increasing realism, reports investigating physical models as a low-cost 3D traditional method are still the subject of considerable interest. The aim of this meta-analysis is to quantitatively…

Open Assessment of Learning (OAoL) is an emerging educational concept derived from the incorporation of Information and Communication Technologies (ICT) to education and is related with the Open Education Movement. In order to improve understanding of OAoL a literature review was conducted as a meta-synthesis of 100 studies on ICT-based assessment…

Smartphones provide a powerful platform for augmented reality (AR). Using a smartphone's camera together with the built in GPS, compass, gyroscope, and touch screen enables the real world environment to be overlaid with contextual digital information. The creation of mobile AR environments is relatively simple, with the development of mobile AR…

Early adolescence is a developmental stage characterized by changes in reasoning, social cognition, and desire for autonomy in youth aged 11-14 (or grades 6-8). This period is also associated with heightened impulsivity and risk-taking that has been linked to school-related challenges such as antisocial behaviors and declining grades. Character…

The ability to design and interpret controlled experiments is an important scientific process skill and a common objective of science standards. Numerous intervention studies have investigated how the control-of-variables-strategy (CVS) can be introduced to students. However, a meta-analysis of 72 intervention studies found that the opportunity to…

Peer tutoring is an instructional strategy that allows students to help one another learn content material through the repetition of key concepts. In more than 40 years of published studies, literature reviews, and meta-analyses of peer tutoring, this quantitative synthesis of the literature is the first to examine the impact of peer tutoring on…

This meta-analysis reviewed 144 studies from 1996 to 2013 using the Beck Depression Inventory-Second Edition. Internal consistency was 0.89 and test-retest reliability 0.75. Convergent comparisons were robust across 43 depression instruments. Structural validity supported both one- and two-factor solutions and diagnostic accuracy varied according…

We conducted a meta-analysis of 31 studies, spanning 30 years, utilizing the WCST in participants with autism. We calculated Cohen's d effect sizes for four measures of performance: sets completed, perseveration, failure-to-maintain-set, and non-perseverative errors. The average weighted effect size ranged from 0.30 to 0.74 for each measure, all…

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…

This article provides a meta-analysis on the effect of academic probation, student-faculty mentoring and need-based grants on various student outcomes. Using 25 (quasi-) experimental studies, we find that academic probation has a significant negative effect on retention (d = -0.17), while it does not have an effect on graduation. Student-faculty…

Studies of interventions' impact on reading self-efficacy have been conducted since the 1980s. The purpose of this project was to conduct a systematic review of these studies because the primary studies often yielded divergent results. Included studies entailed an intervention, addressed reading specifically, and reported explicit pre- and…
