As medical education research advances, it is important that education researchers employ rigorous methods for conducting and reporting their investigations. In this article we discuss several important yet oft neglected issues in designing experimental research in education. First, randomization controls for only a subset of possible confounders.…

After months of waiting, the grant reviews came back: "excellent," "excellent," and "fair." What?! How can this be? Why is the third review so out of line with the first two? On more than one occasion a principal investigator (PI) has been frustrated not only by a negative funding decision but more so by the accompanying reviewer evaluation forms…

Informal science education (ISE) experiences can provide powerful opportunities for people with disabilities to experience and learn about science. When designed to be inclusive, such experiences can lead people with disabilities to feel competent and empowered as science learners, generate excitement and enthusiasm for science, and be equitable…

Over the past thirty years, researchers have documented a remarkable growth in children's social understanding between toddlerhood and the early school years. However, it is still unclear why some children's awareness of others' thoughts and feelings lags so far behind that of their peers. Based on research that spans an extended developmental…

This paper reviews astronomy education research carried out among school students, teachers, and museum visitors over a 35-year period from 1974 until 2008. One hundred and three peer-reviewed journal articles were examined, the majority of whose research dealt with conceptions of astronomical phenomena with 40% investigating intervention…

This study investigates the relationships of domain-general cognitive abilities and domain-specific verbal and mathematical abilities to students' educational characteristics when two theoretically grounded, but competing structural models are applied. In the standard model, a single latent ability causes interindividual differences in the…

Recently, several scholars have suggested that academic self-regulation may be particularly important for students participating in online learning. The purpose of the present study was to develop a quantitative self-report measure of perceived task value and self-efficacy for learning within the context of self-paced, online training, and to…

General education classrooms provide a common milieu for understanding and appropriating results of classroom research projects, which are typically viewed as having little application outside their original contexts. Here, results of an investigation into the "sophomore slump," where grades and class attendance rates typically suffer, are…

The present study examines private speech and strategy-use patterns for solving simple number fact problems in addition. The progressive differentiation by grade between children's levels of private speech internalization--including silence--was investigated and related to children's developmental patterns for subcategories of strategy-use…

Community and culture significantly influence value orientation, perceived needs, and motivation as well as provide the ground for creating shared understanding. All disciplines have their own cultures, and all cultures evolve through cross-cultural exchanges. The computing community has created and documented a sound body of knowledge of…

In this study the authors investigated the use of 5 (i.e., Claudy, Ezekiel, Olkin-Pratt, Pratt, and Smith) R[squared] correction formulas with the Pearson r[squared]. The authors estimated adjustment bias and precision under 6 x 3 x 6 conditions (i.e., population [rho] values of 0.0, 0.1, 0.3, 0.5, 0.7, and 0.9; population shapes normal, skewness…
