This study investigated whether children with language learning disability (LLD) differed from typically-developing peers in their ability to learn meanings of novel words presented during reading. Fifteen 9-11-year-old children with LLD and 15 typically-developing peers read four passages containing 20 nonsense words. Word learning was assessed…

Perfectionistic concerns (i.e., negative reactions to failures, concerns over others' criticism and expectations, and nagging self-doubts) are a putative risk factor for depressive symptoms. This study proposes and supports the existential model of perfectionism and depressive symptoms (EMPDS), a conceptual model aimed at explaining why…

Despite all the speeches, articles, and meetings about data-based instructional decision making, the author's observation after more than 20 years of working with middle and high school teams is that teachers and administrators often make important instructional decisions on the basis of historical precedent, anecdotal information, experience, or…

P. R. Killeen's (2005a) probability of replication ("p[subscript rep]") of an experimental result is the fiducial Bayesian predictive probability of finding a same-sign effect in a replication of an experiment. "p[subscript rep]" is now routinely reported in "Psychological Science" and has also begun to appear in…

In this study, 180 Norwegian fifth-grade students with a mean age of 10.5 years were administered measures of word recognition skills, strategic text processing, reading motivation and working memory. Six months later, the same students were given three different multiple-choice reading comprehension measures. Based on three forced-order…

This study estimates the causal effects of six corrective actions for children's problem behaviors, comparing four types of longitudinal analyses that correct for pre-existing differences in a cohort of 1,464 4- and 5-year-olds from Canadian National Longitudinal Survey of Children and Youth (NLSCY) data. Analyses of residualized gain scores found…

Rough set theory (RST) is an emerging technique used to deal with problems in data mining and knowledge acquisition. However, the RST approach has not been widely explored in the field of academic achievement. This investigation developed an improved RST (IMRST) model, which employs linear discriminant analysis to determine a reduct of RST, and…

This report examines the differences in impact estimates and standard errors that arise when these are derived using state achievement tests only (as pre-tests and post-tests), study-administered tests only, or some combination of state- and study-administered tests. State tests may yield different evaluation results relative to a test that is…

Computer simulations and animations for developing statistical concepts are often not understood by beginners. Hands-on physical simulations that morph into computer simulations are teaching approaches that can build students' concepts. In this paper we review the literature on visual and verbal cognitive processing and on the efficacy of…

School-based response to intervention (RTI) teams must gather, organize, chart, and interpret essential instructional information to make effective adjustments to meet the academic needs of struggling learners. Quantified data such as student proficiency scores, rate of progress trends, and achievement gap results provide the foundation for making…

Using an original dataset collected at a Chinese university and adopting a difference-in-differences research design, this study draws causal inferences regarding the effect of the Government-Subsidized Student Loan Program (GSSLP) on financially needy students at Chinese higher education institutions. Specifically, this study finds that the…

Skills of inference are needed not just to be able to "read between the lines," to detect the unspoken hidden meanings that enrich overall understanding of a text or to draw one's own personal conclusions about a text. They are needed for all the other tasks that teachers want their children to do in handling texts: to understand the effects…

A central theme of research on human development and psychopathology is whether a therapeutic intervention or a turning-point event, such as a family break-up, alters the trajectory of the behavior under study. This article describes and applies a method for using observational longitudinal data to make more transparent causal inferences about the…

People report recognizing discourse inferences at rates that approach target acceptance. Brainerd et al. [Brainerd, C. J., Wright, R., Reyna, V. F., & Mojardin, A. H. (2001). "Conjoint recognition and phantom recollection." "Journal of Experimental Psychology: Learning, Memory, and Cognition, 27", 307-329] proposed that…

In this comment, it is argued that the modification of mental models theory of conditional inference proposed by P. Barrouillet, C. Gauffroy, and J.-F. Lecas to deal with truth value gaps merely patches up a problem in the theory, rather than accomplishing the fundamental and systematic revision that is necessary. It is argued that P. Barrouillet…
