In this study, we examine the impact and the interplay of general giftedness (G) and excellence in mathematics (EM) on high school students' mathematical performance associated with translations from graphical to symbolic representations of functions, as reflected in cortical electrical activity (by means of ERP--event-related…

The goal of this research is to make sensitivity analysis accessible not only to empirical researchers but also to the various stakeholders for whom educational evaluations are conducted. To do this it derives anchors for the omitted variable (OV)-program participation association intrinsically, using the Love plot to present a wide range of…

Through experiencing and reviewing multiple-country endeavors in academic profession study and participating in a new project regarding the academic profession in Asia, the author pinpoints and anticipates the shortcomings of study alone or dominantly questionnaire-based and ignoring the broader social context. The author proposes a new…

The two cross-national indices with gender-differentiated data introduced by the UNDP in 1995, as well as several other such indices developed subsequently, are an important resource for researchers and policy makers interested in gender disparities. Yet questions remain regarding how these indices should be interpreted and how valid they are.…

This paper examines assumptions and beliefs underpinning research into educational technology. It critically reviews some approaches used to investigate the impact of technologies for teaching and learning. It focuses on comparative studies, performance comparisons and attitudinal studies to illustrate how under-examined assumptions lead to…

We used a false-biofeedback methodology to manipulate physiological arousal in order to induce affective states that would influence learners' metacognitive judgments and learning performance. False-biofeedback is a method used to induce physiological arousal (and resultant affective states) by presenting learners with audio stimuli of false heart…

A pilot controlled before-and-after design was used to assess the impact of a new master-level course in evidence-informed policy making on students' basic knowledge in evidence-based practice. The primary outcome variable was the mean percentage of pre-post improvement on the knowledge test. In the treatment group, the mean percentage of pre-post…

The purpose of this study was to explore the effectiveness of the creative inquiry-based science teaching on students' creative science thinking and science inquiry performance. A quasi-experimental design consisting one experimental group (N = 20) and one comparison group (N = 24) with pretest and post-test was conducted. The framework of the…

This literature review on Universal Design for Learning (UDL) included articles from January 1984 through June 2014. We (a) investigated the UDL educational framework without the inclusion of other major K-12 educational frameworks in learning environments, (b) reported researchers' scope and depth of use of the UDL principles, and (c) focused our…

Background: Prior research suggests that 60-74% of males and 16-45% of females with fragile X syndrome (FXS) meet criteria for autism spectrum disorder (ASD) in research settings. However, relatively little is known about the rates of clinical diagnoses in FXS and whether such diagnoses are consistent with those performed in a research setting…

Debate is occurring about which result interpretation aides focused on examining the experimental effect should be used in single-subject experimental research. In this study, we examined seven nonoverlap methods and compared results using each method to judgments of two visual analysts. The data sources for the present study were 36 studies…

This guide for district and school leaders shows how to recognize opportunities to embed randomized controlled trials (RCTs) into planned policies or programs. Opportunistic RCTs can generate strong evidence for informing education decisions--with minimal added cost and disruption. The guide also outlines the key steps to conduct RCTs and responds…

The purpose of this study was to identify and compare common criteria and characteristics for award-winning dissertations utilized by prominent national educational organizations. Formal and informal criteria for award-winning dissertations were examined and compared to distinguish commonalities in the dissertations and award processes.…

Research in non-human animal (hereafter, animal) cognition has found strong evidence that some animal species are capable of meta-cognitively monitoring their mental states. They know when they know and when they do not know. In contrast, animals have generally not shown robust theory of mind (ToM) capabilities. Comparative research uses methods…

Comparability between different educational qualifications is an important issue within policy discourse in the UK. In this context, the comparability of qualification demands has been explored through the use of expert human judgement. The involvement of human judgement in estimating assessment demands has consequences for methodology. This…
