Estimation of within-trial interactions in meta-analysis is crucial for reliable assessment of how treatment effects vary across participant subgroups. However, current methods have various limitations. Patients, clinicians and policy-makers need reliable estimates of treatment effects within specific covariate subgroups, on relative and absolute…

This article provides a commentary within the special issue, Integration: The Keystone of Comprehension. According to most contemporary frameworks, a driving force in comprehension is the reader's ability to generate the links among the words and sentences (ideas) in the texts and between the ideas in the text and what the readers already know. As…

The articles in this special issue of the "Journal of Cognition and Development" examine the cognitive development of children who are following typical and atypical developmental pathways. The articles offer a mixture of theory-based considerations, reviews of the literature, and new empirical data addressing fundamental aspects of…

In this article I make the point that there has been a continuous focus on second language development in second language acquisition research for over 40 years and that there is clear empirical evidence for generalizable developmental patterns. I will both summarize some of the core assumptions of Processability Theory (PT) as an approach to…

This article reports on the development and use of the Developmental Sentence Scoring for Japanese (DSSJ), a new morpho-syntactical measure for Japanese constructed after the model of Lee's English Developmental Sentence Scoring model. Using this measure, the authors calculated DSSJ scores for 84 children divided into six age groups between 2;8…

The ability to self-regulate is important for students at any level, but is especially valuable to those in college, as they are confronted with a great deal of material in a short span of time. Some studies demonstrate that college students are effective self-regulators, while other studies indicate they are not (Peverly, Brobst, Graham, & Shaw,…

Longitudinal studies are necessary to examine individual change over time, with group status often being an important variable in explaining some individual differences in change. Although sample size planning for longitudinal studies has focused on statistical power, recent calls for effect sizes and their corresponding confidence intervals…

The objective of the proposed systematic review is to summarize the available evidence on the effects of prevention and intervention programs aimed at primary and secondary students for increasing school completion or reducing school dropout. Program effects on the closely related outcomes of school attendance (absences, truancy) will also be…

In this article, I describe studies conducted over 25 years with secondary and post-secondary L2 learners in the United States. The evidence from these studies shows that there are important connections between students' early L1 skills and their L2 aptitude and L2 proficiency and that individual differences in students' L1 skills in elementary…

The distinction between automatic processes and controlled processes is a central organizational theme across areas of psychology. However, this dichotomy conceals important differences among qualitatively different processes that independently contribute to ongoing behavior. The Quadruple process model is a multinomial model that provides…

In this article, the authors take a quick comparative look at two superintendents and their districts to better understand how both of them, considered strong leaders, can have very different effects on mean district-level student achievement. Their recent meta-analysis of the effects of district-level leadership on student achievement, summarized…

Examines the differences between German and Vietnamese students in both learning-relevant features and the relation between learning strategies and motivational features. Reveals both communalities (similar patterns of determinants of depth-oriented learning strategies) and differences (longer duration of studies and higher reliance on repetition)…

L. L. Thurstone's (1927) model provides a powerful framework for modeling individual differences in choice behavior. An overview of Thurstonian models for comparative data is provided, including the classical Case V and Case III models as well as more general choice models with unrestricted and factor-analytic covariance structures. A flow chart…

Examines two models of educational theory developed by Franz Fischer. One model defines education as a categorical reflection on the difference between a presupposed versus scientifically-explicable world, while the other grounds moral education on awareness of demands of the other person. Applies the models to the problem of otherness. (CMK)
