Objective: This study sought to examine the efficacy of inoculation message treatments to facilitate resistance to health nutrition-related (HNR) commercial food advertising claims. Design: Data were collected across three phases extending across a 5-week period conducted over two semesters at a Midwest US university. A 2 × 3 between-subjects…

This study investigates whether age-related changes in the structure of 5 complex working memory (WM) tasks (a) reflect a general or domain specific system, (b) follows a similar trajectory across different age spans, and (c) contribute domain general or domain specific resources to achievement measures. The study parsed the sample (N = 2,471)…

The 1990 Individuals with Disabilities Education Act (IDEA) reauthorization introduced transition mandates that included a "student involvement in transition planning" requirement, creating an emphasis on promoting such involvement so as to enhance the self-determination of students with disabilities and positive transition-related…

Background: Cluster randomized experiments that assign intact groups such as schools or school districts to treatment conditions are increasingly common in educational research. Such experiments are inherently multilevel designs whose sensitivity (statistical power and precision of estimates) depends on the variance decomposition across levels.…

Reading achievement scores for adolescents with disabilities are markedly lower than the scores of adolescents without disabilities. For example, 62% of students with disabilities read "below" the basic level on the NAEP Reading assessment, compared to 19% of their nondisabled peers. This achievement gap has been a continuing challenge…

The paper presents a model for addressing the critical question of opportunity to learn for students with disabilities. The model was tested through a two-year study with schools and teachers in three states. Opportunity to learn analysis is critical in this educational era of push toward access and inclusion. The study results indicate that…

Profiling may be a viable means of identifying those creative adolescents who can benefit from specialized guidance and exploration of science, technology, engineering, and mathematics (STEM) fields, arts, and human services. The experimenters developed 1 general and 5 specific profiles including interest, personality, and achievement variables…

Research examining child-care providers' beliefs and behaviour has produced contradictory evidence perhaps because analyses commonly examine providers as a homogenous group. Among providers in the Study of Early Child Care and Youth Development, we used cluster analysis to identify groups based on profiles of beliefs. We found evidence for five…

It is commonly assumed that urban school districts hire teachers late due to issues related to district size and/or restrictions in collectively bargained teacher contracts affecting teacher hiring and transfers between schools. Our investigation of late teacher hiring and collective bargaining is based on a survey of 40 school districts that…

Background: Cluster-randomized experiments that assign intact groups such as schools or school districts to treatment conditions are increasingly common in educational research. Such experiments are inherently multilevel designs whose sensitivity (statistical power and precision of estimates) depends on the variance decomposition across levels.…

This report presents the findings of a rigorous experimental impact evaluation and implementation study of one such intervention, the Content Literacy Continuum (CLC), developed by researchers at the University of Kansas Center for Research on Learning. This evaluation of CLC was conducted by three partnering organizations: REL Midwest, MDRC, and…

The present work addresses the associations between self-reported maternal parenting behaviours and aggression, personality and peer regard of children (n = 119) in early childhood (ages three-six years). A k-means cluster analysis derived types of mothers based on their relative use of autonomy support and restrictive control. Outcomes included…

Institutions of higher education have a vested interest in the health of their student populations, even without the traditional strictures of "in loco parentis". Student health issues involve stress management, healthy diet and exercise, the building of healthy social lives, effective relationship management, and the development of life…

Variation in the parts of ASL signs (i.e., phonological variation) has been explained largely by reference to the influence of the preceding and the following segments. This article examines three linguistic variables in ASL: the sign deaf; the location of a class of signs represented by the verb know; and signs produced with a 1 handshape. For…
