Stability and change in students' achievement goals (AGs) are of great relevance for educational research and practice. In two separate meta-analyses, we investigated the rank-order stability (93 studies, 569 effect sizes, 54,736 students), as well as the mean-level change (157 studies, 1,170 effect sizes, 81,464 students) in AGs throughout…

One-hundred and twenty-two undergraduates completed a survey assessing beliefs that WM is a stable trait, or that it is quality that can be improved with skill training. They then read an authentic set of journal articles in a special issue, which discussed whether a program called CogMed is or is not effective in promoting WM functioning.…

Accurate and consistent reviews of documents describing research studies are essential to valid and generalizable inferences in a meta-analysis. Traditionally a small number of reviewers screen studies using the title, abstract, and possibly the full text to determine a study's eligibility for a meta-analysis. This study explores whether reviewing…

The focus for this literature review developed from reading American research by Oyserman and Destin around the theme of identity and possible selves. The intention of this review was to consider whether an identity-based perspective could be applied to investigate the multiple outcomes of UK care leavers. The aim was to explore the relevant…

Summarizes data related to the stability and variation in the norms for the Raven's Progressive Matrices Test (J. Raven, 1936), a measure of basic cognitive functioning, for different cultural, ethnic, and socioeconomic groups worldwide and within countries. Also considers variation over time and suggests an explanation for the variation in norms…

The problem of change scores' correlation with initial status and the problem of low reliability in the measurement of change are addressed. By treating the correlation between initial status and change as a design problem rather than a statistical issue, research questions can be formulated in terms of changes in the shapes of growth curves…

The Scholastic Aptitude Test (SAT) has been designed to test developed verbal and mathematics reasoning abilities of college-bound students, primarily high school juniors and seniors. For almost a decade there has been a research and development process to evaluate and change the entire SAT program. These changes were implemented in the SAT I:…
