There is a reported association between thyroid disorders and Down syndrome, but is this association based on valid and reliable research evidence? We evaluated thyroid function test results of 110 healthy adults with Down syndrome to determine biochemical thyroid status. Approximately two thirds were biochemically euthyroid when assessed by…

Of the limited number of studies employing positive event (uplift) measures none have published detailed psychometric information about the scale that was used (Maybery and Graham, 2001, Stress and Health 17, pp. 91-104). Building on previous work with university students and employing conceptually distinct measurement strategies (i.e. measuring…

Purpose: Examination of movement parameters and consistency has been used to infer underlying neural control of movement. However, there has been no systematic investigation of whether the way individuals are asked (or cued) to increase loudness alters articulation. This study examined whether different cues to elicit louder speech induce…

A mixed method approach to educational and social inquiry is presented as an important counterpoint to the contemporary debate about what constitutes valid, rigorous, and "scientific" research. By welcoming all legitimate methodological traditions, mixed method inquiry meaningfully engages with difference and thus offers some generative potential…

An extension of G. L. Cates et al. (2003) investigation was conducted to determine if students' cumulative learning rates would be superior for words read under a traditional drill and practice condition (as they were for spelling in the previous study) than under interspersal conditions of varying ratios of unknown to known words. Participants…

The purpose of this study was to explore how satisfied prospective science teachers are with their department (academic staff and administration) at different Faculties of Education in Turkey. For this purpose, Prospective Science Teachers Satisfaction Questionnaire (PSTSQ) was developed by considering related literature. PSTSQ consists of two…

Background: Research reveals that the relationship between a student and a supervisor is so crucial that students cannot afford to leave it to chance. It must be managed. Phillips and Pugh (2000, p. 193) maintains that if students are to do this well, they must understand what their supervisors expect of them. Once they have this "inside…

Recent research has shown that the technical adequacy of assessments for special student populations is relatively undeveloped compared to their general education counterparts; that is, the technical evidence provided and the methods by which this evidence is established do not necessarily account for the unique characteristics of special needs…

Reliable and valid longitudinal residential histories are needed to assess interventions to reduce homelessness and increase community tenure. This study examined the test-retest reliability, sensitivity to change, and concurrent validity of the Residential Time-Line Follow-Back (TLFB) Inventory, a method used to record residential histories in…

This study investigated some issues regarding the validity of the Scholastic Achievement Test (SAT) Subject Test: Korean with Listening. The SAT Korean has been administered just once a year since its inception in 1997. As of March 2006, it had been administered nine times. However, SAT foreign language tests are not as rigorously researched as…

Through study of 32 students' narratives about coping with external threats to their career goals (e.g., denial of admission to the major of their choice), this study examines the following issues: (a) the coping mechanisms student use when faced with threats that loom large, (b) the relation between coping methods employed and whether the goal is…

Purpose: To develop a reliable and valid questionnaire of bilingual language status with predictable relationships between self-reported and behavioral measures. Method: In Study 1, the internal validity of the Language Experience and Proficiency Questionnaire (LEAP-Q) was established on the basis of self-reported data from 52 multilingual adult…

Numerous studies have shown increasing item reliabilities as an effect of the item position in personality scales. Traditionally, these context effects are analyzed based on item-total correlations. This approach neglects that trends in item reliabilities can be caused either by an increase in true score variance or by a decrease in error…

A study investigated the teaching characteristics on which medical students, residents, and faculty focus in their assessment of teaching and how they arrive at their assessments of teaching quality. Results indicate the important predictors of ratings were clinical competence, demonstrated sensitivity toward patients and families, and recognition…

This volume, one in a series in applied linguistics, is a concise handbook of testing theory and practice in foreign language instruction. Two broad categories, "prognosis" and the "evaluation of attainment," are treated in five major chapters, including: (1) prognostic measurement, (2) achievement measurement, (3) proficiency measurement, (4)…
