The relationship between brain volume and intelligence has been a topic of a scientific debate since at least the 1830s. To address the debate, a meta-analysis of the relationship between in vivo brain volume and intelligence was conducted. Based on 37 samples across 1530 people, the population correlation was estimated at 0.33. The correlation is…

Despite the growing number of collaborations between volunteers and professional scientists, research efforts investigating the impacts of such collaborations, which we have termed Public Participation in Scientific Research (PPSR), have been very limited. Examples of PPSR projects include citizen science, volunteer monitoring, and participatory…

The past two decades have seen an emerging trend in urban school governance: mayors taking the reins of school district leadership. The impetus for putting the mayor in charge of a city's schools usually stems from at least one of the following being documented or generally perceived about an urban school district: (1) Lack of accountability; (2)…

This meta-analysis of the experimental literature of distance education (DE) compares different types of interaction treatments (ITs) with other DE instructional treatments. ITs are the instructional and/or media conditions designed into DE courses, which are intended to facilitate student-student (SS), student-teacher (ST), or student-content…

Peer review is valued in higher education, but also widely criticized in terms of potential biases, particularly gender. We evaluate gender differences in peer reviews of grant applications, extending Bornmann, Mutz, and Daniel's meta-analyses that reported small gender differences in favor of men (d = 0.04), but a substantial heterogeneity in…

A systematic literature search for studies reporting effects of Early Intensive Behavioral Intervention identified 34 studies, 9 of which were controlled designs having either a comparison or a control group. We completed a meta-analysis yielding a standardized mean difference effect size for two available outcome measures: change in full-scale…

This article focuses on mentoring program practices in relation to issues of effectiveness, while recognizing that implications for program quality conceptualized more broadly is a key concern in need of greater investigation. The author provides an overview of selected conceptual and methodological issues involved with identification of…

A commonly attempted approach to modifying attitudes regarding people with disabilities is to place people without disabilities in situations that are designed for them to experience what it is like to have a disability. This approach, called disability simulation, continues despite criticisms including a reported lack of effectiveness data and…

Despite overwhelming evidence that gender plays a significant role in the course of numerous psychological disorders, researchers have historically neglected to address gender similarities and differences in their research. Previous reviews of the psychological literature have indicated that personality, psychotherapy, and behavioral psychology…

This article addresses the set of articles in this special issue of "Applied Measurement in Education" and reflects on the issues that underlie the articles. The authors, as a set, represent many of the professionals who have developed and studied the methodological procedures related to instruction-assessment alignment over the past decade. This…

Nearly four decades have passed since the Individuals with Disabilities Education Act (IDEA) ensured access to public education for students with disabilities in the United States. During the years following its introduction, there was a growing recognition that helping students, especially students with disabilities, in their transitions from…

A gender gap in mathematics achievement persists in some nations but not in others. In light of the underrepresentation of women in careers in science, technology, mathematics, and engineering, increasing research attention is being devoted to understanding gender differences in mathematics achievement, attitudes, and affect. The gender…

This thesis explored the history of calculator usage in mathematics classrooms in the United States since 1975 with a focus on the attitudes of parents, educators, and national organizations. The influence of historical events, people, organizations, research, and trends was explored in depth. Studying the changes that calculators have brought to…

Analogous thinking has been commonly discussed as being an inherent and distinguishing characteristic of human cognition (e.g., Gentner, 2010; Goldstone, Day, & Son, 2010; Holyoak, in press; Rittle-Johnson & Star, in press). Gentner (2003) has argued that as part of the human cognitive toolbox, comparison accompanied by the relational language to…

Eighty elected leaders and 388 followers were sampled to test the relationships between leaders' emotional intelligence and the quality of leader-member exchange. Results of the field study found a significant relationship between leaders' emotional intelligence (total) and leader-member exchange quality. Specific subscales of emotional…
