Classroom communication between deaf students was modeled using a question-and-answer game. Participants consisted of student pairs that relied on spoken language, pairs that relied on American Sign Language (ASL), and mixed pairs in which one student used spoken language and one signed. Although the task encouraged students to request…

Most research examining the efficacy of early grade retention has been limited to outcomes during elementary school. A notable gap in the retention literature is the dearth of studies examining outcomes during late adolescence. The results of this prospective longitudinal study include comparisons among four unique samples: (1) early grade…

We designed a professional development (PD) program to increase the teacher efficacy of mathematics teachers. We randomly assigned 106 Grade 6 teachers in 1 school district to treatment and control conditions in a delayed-treatment design. The PD explicitly addressed 4 sources of teacher-efficacy information identified in social-cognition theory…

Studies using fear-conditioning paradigms have found that anxiety patients are more conditionable than individuals without these disorders, but these effects have been demonstrated inconsistently. It is unclear whether these findings have etiological significance or whether enhanced conditionability is linked only to certain anxiety…

This article reports on a research effort that investigated whether the use of Microcomputer-Based Labs (MBLs), implemented within an inquiry-based activity sequence on phase transformations (melting and freezing), contributes to the development of fourth grade (9-10 year-old) students' conceptual understanding and ability to construct and…

The problem is the perceived academic shortcomings of America's public schools because of high stakes testing that is expected to increase along with limited funds and resources. The purpose of this study was to find the benefits of the extracurricular activity that students are already participating in at Paramount High School. This is a…

This meta-analysis examined whether writing about stressful experiences affects health care utilization (HCU) compared with writing on neutral topics or no-writing control groups. Randomized controlled trials of 30 independent samples representing 2,294 participants were located that contained sufficient information to calculate effect sizes.…

This work examines the association between symbols and their representation in adult developmental dyscalculia and dyslexia. Experiment 1 used comparative judgment of numerals, and it was found that in physical comparisons (e.g., 3-5 vs. 3-5) the dyscalculia group showed a significantly smaller congruity effect than did the dyslexia and the…

The processes behind the transition from consistently failing tests of false belief understanding to consistently passing the tests was investigated by tracking changes in children's mental state understanding. Participants were 42 children (aged 3;1 to 4;3). There were two conditions; an experimental condition in which children were tested on a…

It is increasingly argued that the effectiveness of health promotion interventions should be measured to inform policy and practice. The randomized controlled trial (RCT) continues to be regarded as the "gold standard" of health services research but health promotion practitioners have raised concerns about the RCT's appropriateness for evaluating…

Background: The objective of this study was to investigate the tendency for local processing style ("weak central coherence") and executive dysfunction in parents of subjects with an autism spectrum disorder (ASD) compared with parents of individuals with early onset schizophrenia (EOS) and mental retardation (MR). Method: Sixty-two…

This study examined the effect of the Ornish Program for Reversing Heart Disease and cardiac rehabilitation(CR) on psychosocial risk factors and quality of life in patients with confirmed coronary artery disease. Participants had previously undergone a revascularization procedure. The 84 patients self-selected to participate in the Ornish Program…

Background: Periodontal disease in Down's syndrome (DS) individuals develops earlier and is more rapid and extensive than in age-matched normal individuals. The present study evaluated a group of DS patients, who had been participating in a 10-year preventive dental programme, for the impact of the programme on their periodontal status. Methods:…

Specific reading disability (SRD) is now widely recognised as often being caused by phonological processing problems, affecting analysis of spoken as well as written language. According to one theoretical account, these phonological problems are due to low-level problems in auditory perception of dynamic acoustic cues. Evidence for this has come…

The authors tested the effectiveness of 2 group career interventions for 73 battered women who were randomly assigned to 1 of 2 treatment conditions or a wait-list control group. Both interventions included the 5 most effective career intervention components identified by S. D. Brown and N. E. Krane (2000), and 1 of the interventions also was…
