The aim was to develop a new instrument for measuring length of sleep as well as television and computer habits in school-age children. A questionnaire was constructed for use when children visit the school health care unit. Three aspects of the validity of the questionnaire were examined: its face validity, content validity, and construct…

Several government agencies are seeking quality improvement in environmental policy documents by asking for the implementation of Plain Language (PL) guidelines. Our mixed-methods research examines whether the application of certain PL guidelines affects the comprehension and perceptions of readers of environmental policy documents. Results show…

The language of non-native speakers is less reliable than the language of native speakers in conveying the speaker's intentions. We propose that listeners expect such reduced reliability and that this leads them to adjust the manner in which they process and represent non-native language by representing non-native language in less detail.…

Outcomes assessments are gaining great attention in higher education because of increased demand for accountability. These assessments are widely used by U.S. higher education institutions to measure students' college-level knowledge and skills, including students who speak English as a second language (ESL). For the past decade, the increasing…

The purpose of this study was to demonstrate the use of Latent Growth Modeling (LGM) as a method for estimating reliability of Curriculum-Based Measurement (CBM) progress-monitoring data. The LGM approach permits the error associated with each measure to differ at each time point, thus providing an alternative method for examining of the…

Students in the USA have fallen near the bottom in international competitions and tests in mathematics and science. It is thought that extrinsic factors such as family, community, and schools might be more influential than intrinsic attitudes toward science interest. However, there are relatively few valid and reliable measures of intrinsic…

Prior work shows that children can make inductive inferences about objects based on their labels rather than their appearance (Gelman, 2003). A separate line of research shows that children's trust in a speaker's label is selective. Children accept labels from a reliable speaker over an unreliable speaker (e.g., Koenig & Harris, 2005). In the…

The Particulate Nature of Matter and Chemical Bonding Diagnostic Instrument (Othman J., Treagust D. F. and Chandrasegaran A. L., (2008), "Int. J. Sci. Educ.," 30(11), 1531-1550) is used to investigate college students' understanding of two chemistry concepts: particulate nature of matter and chemical bonding. The instrument, originally…

The purpose of this study was to develop and validate an instrument to measure dimensions of the concept of a good death held by Taiwanese children. The sample consisted of 1,698 Taiwanese children, approximately 12-14 years of age. Participants completed the self-administered Good Death Concept Scale (GDCS), which consists of 30 statements…

The purpose of this pilot study was to develop and evaluate an instrument for measuring Greek elementary physical educators' knowledge of student assessment. A multiple-choice questionnaire comprised of items about concepts, methods, tools, and types of student assessment in physical education was designed and tested. The initial 35-item…

The present study was designed to examine the psychometric properties of the Chinese-translated Behavioral Regulation in Exercise Questionnaire-2 (Markland & Tobin, 2004). A sample of Chinese university students (N =555) was invited to take part in this study. Confirmatory factor analysis was employed to examine the factorial validity, and the…

Objective: The "DSM-IV-TR "criteria for a manic episode and bipolar disorder (BD) were developed for adults but are used for children. The manner in which clinicians and researchers interpret these criteria may have contributed to the increase in BD diagnoses given to youth. Research interviews are designed to improve diagnostic reliability and…

The Liebowitz Social Anxiety Scale (LSAS) is one of the most commonly used measures of social anxiety symptoms. To date, no study has examined its psychometric properties in a Latino sample. The authors examined the reliability, temporal stability, and convergent validity of the LSAS in 73 Latinos diagnosed with an anxiety disorder. The original…

This study examines a 118-year continuous record of retention and graduation rates at a public university for long-term trends not observable in shorter studies. While the first year retention rates stayed level over much of this period, second year rates increased steadily by 1.2% per decade. In contrast, graduation rates at 4 years compared to 6…

The first large-scale, nationwide academic achievement testing program using Stanford Achievement Test (Stanford) for deaf and hard-of-hearing children in the United States started in 1969. Over the past three decades, the Stanford has served as a benchmark in the field of deaf education for assessing student academic achievement. However, the…
