Baggetta, Matthew; Bredenkamp, David M. – Sociological Methods & Research, 2021
Scholars of civil society organizations (CSOs) have long been concerned with face-to-face interactions among participants at meetings, events, and activities--what we collectively call "convenings." Small-N ethnographies have uncovered substantial differences in the dynamics of convenings within and across CSOs. Large-N quantitative…

Greene, Jennifer C. – Research in the Schools, 2021
This reflective commentary on the character and role of methodology in educational and social inquiry recounts my 45-year journey as an applied researcher and evaluator, primarily in the domain of education. The journey starts in graduate school in the early 1970s, where the methodological challenge was to master "the proper methods, properly…

Nam, Yeji; Hong, Sehee – Educational and Psychological Measurement, 2021
This study investigated the extent to which class-specific parameter estimates are biased by the within-class normality assumption in nonnormal growth mixture modeling (GMM). Monte Carlo simulations for nonnormal GMM were conducted to analyze and compare two strategies for obtaining unbiased parameter estimates: relaxing the within-class normality…

Burian, Alexis N.; Zhao, Wufan; Lo, Te-Wen; Thurtle-Schmidt, Deborah M. – Biochemistry and Molecular Biology Education, 2021
To fully appreciate genetics, one must understand the link between genotype (DNA sequence) and phenotype (observable characteristics). Advances in high-throughput genomic sequencing technologies and applications, so-called "-omics," have made genetic sequencing readily available across fields in biology from applications in…

Reddy, Pritika; Chaudhary, Kaylash; Sharma, Bibhya; Chand, Ronil – Electronic Journal of e-Learning, 2022
The individuals living in the 21st century have become the consumers of digital innovations and have to adapt, adopt and adapt to the new norm of surviving and thriving in the digital society. Familiarity with the latest technologies is not the only requirement for survival. One also needs to have relevant digital competencies to complete tasks…

Deng, Lifang; Chan, Wai – Educational and Psychological Measurement, 2017
Reliable measurements are key to social science research. Multiple measures of reliability of the total score have been developed, including coefficient alpha, coefficient omega, the greatest lower bound reliability, and others. Among these, the coefficient alpha has been most widely used, and it is reported in nearly every study involving the…

Pustejovsky, James E.; Rodgers, Melissa A. – Research Synthesis Methods, 2019
Publication bias and other forms of outcome reporting bias are critical threats to the validity of findings from research syntheses. A variety of methods have been proposed for detecting selective outcome reporting in a collection of effect size estimates, including several methods based on assessment of asymmetry of funnel plots, such as the…

Wallin, Gabriel; Wiberg, Marie – Journal of Educational and Behavioral Statistics, 2019
When equating two test forms, the equated scores will be biased if the test groups differ in ability. To adjust for the ability imbalance between nonequivalent groups, a set of common items is often used. When no common items are available, it has been suggested to use covariates correlated with the test scores instead. In this article, we reduce…

Wind, Stefanie A. – Language Testing, 2019
Differences in rater judgments that are systematically related to construct-irrelevant characteristics threaten the fairness of rater-mediated writing assessments. Accordingly, it is essential that researchers and practitioners examine the degree to which the psychometric quality of rater judgments is comparable across test-taker subgroups.…

Swann, G. M. Peter – Journal of Economic Education, 2019
Many empirical economists say that the teaching of econometrics is unbalanced, and students are not well-prepared for the serious problems they will encounter with real data. Here, the author considers the problem of noisy data, which is present in most econometric studies, but receives far too little attention. Most econometric studies are done…

Kim, Hanjoe – New Directions for Child and Adolescent Development, 2019
Propensity score analysis is a statistical method that balances pre-existing differences across treatment conditions achieving a similar condition as randomization and thus, allowing the estimation of causal effects in non-randomized experimental designs. The four stages in propensity score analysis are (1) propensity score estimation, (2)…

Sullivan, Matthew O.; Gallagher, Louise; Heron, Elizabeth A. – Journal of Autism and Developmental Disorders, 2019
Aggressive behaviour is a significant issue for individuals with autism spectrum disorder (ASD), yet our understanding is limited compared to aggression in typically developing populations. This study examined behavioural, adaptive and cognitive data provided by the Simons Simplex Collection (N = 2184) to identify behavioural subgroups in children…

Belfield, Clive R.; Brooks Bowden, A. – Educational Researcher, 2019
Cost, cost-effectiveness, and benefit-cost analysis are methods used by economists to evaluate public policies. Essentially, these methods rely on impact evaluations, that is, research studies of efficacy and effectiveness. However, in most research in education, these cost and impact evaluations are performed separately. This separation creates…
