The Relation of Moral Emotion Attributions to Prosocial and Antisocial Behavior: A Meta‐Analysis

This meta‐analytic review of 42 studies covering 8,009 participants (ages 4–20) examines the relation of moral emotion attributions to prosocial and antisocial behavior. A significant association is found between moral emotion attributions and prosocial and antisocial behaviors (d = .26, 95% CI [.15, .38]; d = .39, 95% CI [.29, .49]). Effect sizes differ considerably across studies and this heterogeneity is attributed to moderator variables. Specifically, effect sizes for predicted antisocial behavior are larger for self‐attributed moral emotions than for emotions attributed to hypothetical story characters. Effect sizes for prosocial and antisocial behaviors are associated with several other study characteristics. Results are discussed with respect to the potential significance of moral emotion attributions for the social behavior of children and adolescents.     

Instructing Struggling Older Readers: A Selective Meta‐Analysis of Intervention Research

This article synthesizes the experimental literature on reading interventions for upper elementary and middle school students identified with reading disabilities on norm‐referenced reading measures. Ten studies (12 independent samples) yielded 70 effect sizes on norm‐referenced reading measures with an aggregated mean of 0.41 (SE= .04) in favor of the experimental condition. Moderate effect sizes emerged on norm‐referenced measures of word identification (M= 0.41), decoding (M= 0.43), and comprehension (M= 0.73) and low effect sizes for fluency (M=–.29). Intervention outcomes did not significantly vary as a function of the reading skills measured, type of reading instruction, and/or variations in sample characteristics. Studies yielding low and relatively moderate effect sizes shared a number of instructional components. Overall, the magnitude of the results for experimental reading intervention studies for students with reading disabilities in the middle school age range was small to moderate. Implications of the study were discussed.     

An Implicit Theories of Personality Intervention Reduces Adolescent Aggression in Response to Victimization and Exclusion

Adolescents are often resistant to interventions that reduce aggression in children. At the same time, they are developing stronger beliefs in the fixed nature of personal characteristics, particularly aggression. The present intervention addressed these beliefs. A randomized field experiment with a diverse sample of Grades 9 and 10 students (ages 14–16, n = 230) tested the impact of a 6‐session intervention that taught an incremental theory (a belief in the potential for personal change). Compared to no‐treatment and coping skills control groups, the incremental theory group behaved significantly less aggressively and more prosocially 1 month postintervention and exhibited fewer conduct problems 3 months postintervention. The incremental theory and the coping skills interventions also eliminated the association between peer victimization and depressive symptoms.     

Formative Assessment: A Meta‐Analysis and a Call for Research

An effect size of about .70 (or .40–.70) is often claimed for the efficacy of formative assessment, but is not supported by the existing research base. More than 300 studies that appeared to address the efficacy of formative assessment in grades K‐12 were reviewed. Many of the studies had severely flawed research designs yielding uninterpretable results. Only 13 of the studies provided sufficient information to calculate relevant effect sizes. A total of 42 independent effect sizes were available. The median observed effect size was .25. Using a random effects model, a weighted mean effect size of .20 was calculated. Moderator analyses suggested that formative assessment might be more effective in English language arts (ELA) than in mathematics or science, with estimated effect sizes of .32, .17, and .09, respectively. Two types of implementation of formative assessment, one based on professional development and the other on the use of computer‐based formative systems, appeared to be more effective than other approaches, yielding mean effect size of .30 and .28, respectively. Given the wide use and potential efficacy of good formative assessment practices, the paucity of the current research base is problematic. A call for more high‐quality studies is issued.     

Meta‐Analysis of Mathematic Basic‐Fact Fluency Interventions: A Component Analysis

Mathematics fluency is a critical component of mathematics learning yet few attempts have been made to synthesize this research base. Seventeen single‐case design studies with 55 participants were reviewed using meta‐analytic procedures. A component analysis of practice elements was conducted and treatment intensity and feasibility were examined. Findings suggest that drill and practice with modeling produced the largest effect sizes. Treatments with more than 3 components yielded higher effect sizes than those with fewer than 3, and a combination of treatment agents lead to better outcomes than a single agent. Other findings pertaining to prebaseline assessment, treatment time, experimental design employed, and treatment setting are also discussed.     

Meta‐analysis and mega‐analysis: A simple introduction

Statistical methods are increasingly being used to integrate findings from the ever‐expanding universe of empirical research. Meta‐analysis encompasses various techniques for synthesizing summary statistics, and mega‐analysis pools raw data across studies. This paper offers an introduction to meta‐analysis and mega‐analysis that complements the study of analysis of variance (ANOVA). After a brief conceptual discussion, we provide simple numerical examples.     

Science Instruction for Students with Learning Disabilities: A Meta‐Analysis

Although science has received much attention as a political and educational initiative, students with learning disabilities (LD) perform significantly lower than their nondisabled peers. This meta‐analysis evaluates the effectiveness of instructional strategies in science for students with LD. Twelve studies were examined, summarized, and grouped according to the type of strategy implemented. Effect sizes (ES) were calculated for each study. Across all studies, a mean ES of .78 was obtained, indicating a moderate positive effect on students with LD science achievement. Findings also align with past reviews of inquiry‐based instruction for students with special needs, indicating that students with LD need structure within an inquiry science approach in order to be successful. Additionally, results suggest that mnemonic instruction is highly effective at increasing learning disabled students' acquisition and retention of science facts.     

Feeling Good,Happy, and Proud: A Meta‐Analysis of Positive Ethnic–Racial Affect and Adjustment

One point of intersection in ethnic and racial identity research is the conceptual attention paid to how positively youth feel about their ethnicity or race, or positive ethnic–racial affect. This article reports results of a series of meta‐analyses based on 46 studies of this dimension and psychosocial, academic, and health risk outcomes among ethnic and racial minority youth. The overall pattern of results suggests that positive ethnic–racial affect exhibited small to medium associations (r range = |.11| to |.37|) with depressive symptoms, positive social functioning, self‐esteem, well‐being, internalizing, externalizing, academic achievement, academic attitudes, and health risk outcomes. Implications for theory and research about the role of positive ethnic–racial affect among youth growing up in an increasingly diverse society are discussed.     

The Effects of Read‐Aloud Accommodations for Students With and Without Disabilities: A Meta‐Analysis

Read‐aloud accommodations have been proposed as a way to help remove barriers faced by students with disabilities in reading comprehension. Many empirical studies have examined the effects of read‐aloud accommodations; however, the results are mixed. With a variance‐known hierarchical linear modeling approach, based on 114 effect sizes from 23 studies, a meta‐analysis was conducted to examine the effects of read‐aloud accommodations for students with and without disabilities. In general, both students with disabilities and students without disabilities benefited from the read‐aloud accommodations, and the accommodation effect size for students with disabilities was significantly larger than the effect size for students without disabilities. Further, this meta‐analysis reveals important factors that influence the effects of read‐aloud accommodations. For instance, the accommodation effect was significantly stronger when the subject area was reading than when the subject area was math. The effect of read‐aloud accommodations was also significantly stronger when the test was read by human proctors than when it was read by video/audio players or computers. Finally, the implications, limitations, and directions for future research are discussed.     

A Meta‐Analysis of Research on the Read Aloud Accommodation

Read aloud is a testing accommodation that has been studied by many researchers, and its use on K‐12 assessments continues to be debated because of its potential to change the measured construct or unfairly increase test scores. This study is a summary of quantitative research on the read aloud accommodation. Previous studies contributed information to compute average effect sizes for students with disabilities, students without disabilities, and the difference between groups for reading and mathematics using a random effects meta‐analytic approach. Results suggest that (1) effect sizes are larger for reading than for math for both student groups, (2) the read aloud accommodation increases reading test scores for both groups, but more so for students with disabilities, and (3) mathematics scores gains due to the read aloud accommodation are small for both students with and without disabilities, on average. There was some evidence to suggest larger effects in elementary school relative to middle and high school and possible mode effects, but more studies are needed within levels of the moderator variables to conduct statistical tests.     

Mean Effects of Test Accommodations for ELLs and Non‐ELLs: A Meta‐Analysis of Experimental Studies

The objective was to examine the impact of different types of accommodations on performance in content tests such as mathematics. The meta‐analysis included 14 U.S. studies that randomly assigned school‐aged English language learners (ELLs) to test accommodation versus control conditions or used repeated measures in counter‐balanced order. Individual effect sizes (Glass's d) were calculated for 50 groups of ELLs and 32 groups of non‐ELLs. Individual effect sizes for English language and native language accommodations were classified into groups according to type of accommodation and timing conditions. Means and standard errors were calculated for each category. The findings suggest that accommodations that require extra printed materials need generous time limits for both the accommodated and unaccommodated groups to ensure that they are effective, equivalent in scale to the original test, and therefore more valid owing to reduced construct‐irrelevant variance. Computer‐administered glossaries were effective even when time limits were restricted. Although the Plain English accommodation had very small average effect sizes, inspection of individual effect sizes suggests that it may be much more effective for ELLs at intermediate levels of English language proficiency. For Spanish‐speaking students with low proficiency in English, the Spanish test version had the highest individual effect size (+1.45).     

Writing Characteristics of Students with Attention Deficit Hyperactive Disorder: A Meta‐Analysis

Students with Attention Deficit Hyperactivity Disorders (ADHD) frequently experience significant difficulty mastering basic academic skills. This meta‐analysis focuses on one specific potential area of learning difficulties for these students: namely, writing. To identify the extent and depth of the potential writing challenges faced by students with ADHD, we conducted a meta‐analysis comparing the writing performance of grade 1 to 12 students with ADHD to their normally achieving peers. We located 44 papers, yielding 45 studies with 87 effect sizes. The average weighted effect sizes showed that students with ADHD obtained lower scores than their normally achieving peers for writing quality (–0.78), output (–0.64), number of genre elements (–0.69), vocabulary (–0.76), spelling (–0.80), and handwriting (–0.62). Contrary to expectations, moderator analyses found that neither study quality nor the source from which ADHD students were drawn (i.e., school/community vs. clinic/hospital) accounted for variability above sampling error alone.     

Family Correlates of False Belief Understanding in Early Childhood: A Meta‐Analysis

This meta‐analysis seeks to integrate findings from 25 years of research on family correlates of young children's false belief understanding (FBU). Using data from 93 studies of 3‐ to 7‐year‐old children, we examined the correlations between FBU and four of the most widely studied family factors: parental socioeconomic status, number of siblings, parental mental‐state talk, and mind‐mindedness. FBU exhibited modest associations with each family variable and these associations held even when individual differences in verbal ability were taken into account. Moderator analyses revealed key child‐related factors (e.g., age, gender) as well as methodological factors that amplified or attenuated the relations between FBU and each family variable. Crucially, available longitudinal data highlight the importance of family factors in the development of FBU.     

A Meta‐Analysis of the Relationship Between Experiential Learning and Learning Outcomes

Experiential learning activities have been used for over 40 years with the hope that they increase students learning. However, a definitive study that showed their overall effectiveness has not been produced. The purpose of this study is to address this gap in the literature. This meta‐analysis examined a 43‐year span and identified 13,626 journal articles, dissertations, thesis articles, and conference proceedings written about experiential learning and found only 89 of these studies contained empirical data with both a treatment and control group. Meta‐analysis of these studies show that students experienced superior learning outcomes when experiential pedagogies were employed. Further, learning outcomes were almost a half standard deviation higher (d = .43) in classes employing experiential learning pedagogies versus traditional learning environments. This review definitively, and quantitatively, shows the importance of experiential learning activities. We use these results to discuss future research areas that need to be addressed based on our analysis of potential moderators and provide recommendations on how to best employ experiential learning pedagogies.     

Enduring Association Between Parenting and Cortisol: A Meta‐analysis

Warm caregiving is associated with concurrent hypothalamic–pituitary–adrenocortical (HPA) axis function, although the persistence of this association over time is less established. Using longitudinal and intervention studies, this meta‐analysis examined the enduring association of parental warmth (measured when children were ages < 1 through 15 years) with basal cortisol, reactivity and recovery (measured when children were ages < 1 through 25 years; k = 38; N = 6,608). These studies demonstrate no overall associations between parenting and children's HPA axis; instead there are small associations that vary based on moderators such as socioeconomic status, developmental stage, study design and stressor type, though many moderators are confounded. This first wave of studies indicates that the enduring association between parenting and cortisol is small and only understood in the context of other factors, and directly informs four sets of methodological and theoretical recommendations to strengthen this literature.     

Promoting Positive Youth Development Through School‐Based Social and Emotional Learning Interventions: A Meta‐Analysis of Follow‐Up Effects

This meta‐analysis reviewed 82 school‐based, universal social and emotional learning (SEL) interventions involving 97,406 kindergarten to high school students (M_age = 11.09 years; mean percent low socioeconomic status = 41.1; mean percent students of color = 45.9). Thirty‐eight interventions took place outside the United States. Follow‐up outcomes (collected 6 months to 18 years postintervention) demonstrate SEL's enhancement of positive youth development. Participants fared significantly better than controls in social‐emotional skills, attitudes, and indicators of well‐being. Benefits were similar regardless of students’ race, socioeconomic background, or school location. Postintervention social‐emotional skill development was the strongest predictor of well‐being at follow‐up. Infrequently assessed but notable outcomes (e.g., graduation and safe sexual behaviors) illustrate SEL's improvement of critical aspects of students’ developmental trajectories.     

Language‐Focused Interventions on Math Performance for English Learners: A Selective Meta‐Analysis of the Literature

This meta‐analysis synthesized research on math performance outcomes for English learners (EL) as a function of language‐focused (math vocabulary) interventions. We included group and single‐subject design studies with children from kindergarten to 8th grade (3,766 students for group, 30 for single‐subject). Group studies yielded a mean Hedges’ g of 0.26 in favor of the interventions relative to the control conditions, whereas single‐subject studies yielded a mean Percentage of Non‐Overlapping Data of 81.01% and Phi coefficient of .66 relative to baseline. Although group studies yielded small effect sizes (ESs), we found significant moderators for grade level, intervention focus, and length of intervention. Single‐subject studies yielded higher ESs than group studies, and were considered generally effective, with a high ES. This finding was attributed to a direct focus on children with math difficulties and one‐to‐one instruction. The implications for practice and future research are discussed.     

Relations Between False Belief Understanding and Executive Function in Early Childhood: A Meta‐Analysis

The association between executive function (EF) and theory of mind (ToM) has been hotly debated for 20 years. Competing accounts focus on: task demands, conceptual overlap, or functional ties. Findings from this meta‐analytic review of 102 studies (representing 9,994 participants aged 3–6 years) indicate that the moderate association between EF and one key aspect of ToM, false belief understanding (FBU) is: (a) similar for children from different cultures, (b) largely consistent across distinct EF tasks, but varies across different types of false belief task, and (c) is asymmetric in that early individual differences in EF predict later variation in FBU but not vice versa. These findings support a hybrid emergence‐expression account and highlight new directions for research.     

Effects of a Pre-Kindergarten Mathematics Intervention: A Randomized Experiment

Abstract

Research indicates that a socioeconomic status-related gap in mathematical knowledge appears early and widens during early childhood. Young children from economically disadvantaged families receive less support for mathematical development both at home and in preschool. Consequently, children from different socioeconomic backgrounds enter elementary school at different levels of readiness to learn a standards-based mathematics curriculum. One approach to closing this gap is the development and implementation of effective mathematics curricula for public preschool programs enrolling economically disadvantaged children. A randomized controlled trial was conducted in 40 Head Start and state preschool classrooms, with 278 children, to determine whether a pre-kindergarten mathematics intervention was effective. Intervention teachers received training that enabled them to implement with fidelity, and a large majority of parents regularly used math activities teachers sent home. Intervention and control groups did not differ on math assessments at pretest; however, gain scores of intervention children were significantly greater than those of control children at posttest. Thus, the intervention reduced the gap in children's early mathematical knowledge.     

Analysis of Personality,Suicide, and Self‐Injury in Emerging Adulthood

Nonsuicidal self‐injury (NSSI) is a maladaptive coping strategy that is of significant clinical concern for behavioral health professionals in college settings. Relationships between NSSI, acquired capability for suicide, interpersonal cognitions, and five‐factor model personality traits were assessed in a survey‐based study that included 192 young adults in a college setting. Results indicated that those with an affirmative suicide attempt history, greater acquired capability for suicide, and elevated neuroticism had an increased likelihood of lifetime NSSI.
