The ability to adjust language register, or style, according to listener needs was assessed in 38 high-functioning children and adolescents with ASD. Participants were asked to explain the process of going to a restaurant to a series of listeners who varied in linguistic competence. Results showed that participants with ASD spontaneously…

Standardized effect sizes and confidence intervals thereof are extremely useful devices for comparing results across different studies using scales with incommensurable units. However, exact confidence intervals for standardized effect sizes can usually be obtained only via iterative estimation procedures. The present article summarizes several…

Impaired diachronic thinking--(the propensity and capacity to think about events spreading across time)--was demonstrated in a 2-Phase study in which children with autism were compared with age and ability matched controls. Identical tests of diachronic thinking were administered in both phases of the study, but to different participant groups,…

This study evaluated a targeted intervention designed to alleviate body image and eating problems in adolescent girls that was delivered over the internet so as to increase access to the program. The program consisted of six, 90-minute weekly small group, synchronous on-line sessions and was facilitated by a therapist and manual. Participants were…

Efficient and effective lifelong learning requires that learners can make well informed choices from a vast amount of learning opportunities. This article proposes to support learners by drawing on principles of self-organization and indirect social navigation; by analysing choices made by learners who went before and feeding this information back…

Purpose: To test the hypothesis that ankylosing spondylitis (AS) alters the pattern of chest wall motion during speech production. Method: The pattern of chest wall motion during speech was measured with respiratory inductive plethysmography in 6 participants with advanced AS (5 men, 1 woman, age 45 plus or minus 8 years, Schober test 1.45 plus or…

Singaporean Chinese children diagnosed with dysorthographia in English language undergo an intensive spelling intervention program that teaches them to use either of the two spelling methods: lexical and/or phonological spelling strategies. Nevertheless, many of them continue to perform poorly in their spelling. A pretest-posttest experimental…

Background: To attain accurate information about student performance, teachers must apply sound classroom assessment practices. First, teachers need to be able to understand and identify the purpose of their assessments. Teachers also need to provide their students with clear learning targets, in language that students can easily understand, so…

In the No Child Left Behind Act (NCLB), Congress called for the U.S. Department of Education (ED) to conduct a rigorous study of the conditions and practices under which educational technology is effective in increasing student academic achievement. A 2007 report presenting study findings for the 2004-2005 school year, indicated that, after one…

This study explored the influence of strengths-based development on leadership practices among undergraduate college students while controlling for gender, years of leadership experience, and number of completed leadership courses using a quasi-experimental approach with a randomized control-group pretest-posttest research design. The sample…

The current state of health of the United States, including physical inactivity, dietary intake, and overall lifestyle habits is of concern for educators. Specifically, the health of the college population appears to be under-represented in health and wellness research. The purpose of this study was to evaluate a 15-week university wellness-based…

There has been significant interest in the role of anxiety sensitivity (AS) in the anxiety disorders. In this meta-analysis, we empirically evaluate differences in AS between anxiety disorders, mood disorders, and nonclinical controls. A total of 38 published studies (N = 20,146) were included in the analysis. The results yielded a large effect…

This study investigated the comparative efficiency of Web-based instruction (WBI) and traditional teaching methods on preservice teachers' fraction knowledge. Students' knowledge of fractions was measured using a Fraction Knowledge Test. The test consisted of 32 items and was administered as pre- and posttests to a total of 42 preservice teachers…

This study is an experimental introduction of web-based lecture delivery into a majors-level introductory biology course. Web-based delivery, achieved through the use of prerecorded Voice-Over PowerPoint video lectures, was introduced on a limited basis to an experimental section while a control group, with the same instructor, received standard…

The purpose of this study was to assess the pedagogical equivalence, as determined by knowledge gains, and the pedagogical effectiveness of certain components in a video-driven multimedia, web-based professional development training program as compared to a traditional, face-to-face program under real-world constraints of time and limited economic…
