Campbell and Skinner used an A-B design to evaluate the effects of the Timely Transitions Game (TTG) on room-to-room transitions in a sixth-grade classroom. The TTG incorporated explicit timing, publicly posted feedback, and an interdependent group contingency with randomly selected transitions and criteria. The purpose of the current study was to…

This article describes a study that examined the reliability and validity of scores on the Big Five Inventory (BFI; O. P. John, E. M. Donahue, & R. L. Kentle, 1991) in a sample of 336 African American college students. Results from the study indicated moderate reliability and structural validity for BFI scores. Additionally, BFI subscales had few…

The standard error of measurement usefully provides confidence limits for scores in a given test, but is it possible to quantify the reliability of a test with just a single number that allows comparison of tests of different format? Reliability coefficients do not do this, being dependent on the spread of examinee attainment. Better in this…

Background: Claims that children with reading and oral language deficits have impaired perception of sequential sounds are usually based on psychophysical measures of auditory temporal processing (ATP) designed to characterise group performance. If we are to use these measures (e.g., the Tallal, 1980, Repetition Test) as the basis for intervention…

The purpose of this research was to develop and validate a new instrument, the "Mental State in Learning Environment Questionnaire" (MSLEQ), to assess student's mental state in a given learning environment. The MSLEQ has high internal consistency reliability values between 0.70-0.92 as well as good construct validity and predictive validity. After…

This paper addresses doubts concerning the reliability of knowledge being created by double loop learning processes. Popper's ontological worlds are used to explore the philosophical basis of the way that individual experiences are turned into organisational knowledge, and such knowledge is used to generate organisational learning. The paper…

This article describes a study that emerged as a result of the severe acute respiratory syndrome crisis that struck Hong Kong in 2003. One outcome of the severe acute respiratory syndrome crisis was that all personnel in all educational institutions in Hong Kong were compelled to wear face masks for the period April-August 2003. Consequently, the…

Large and reliable laterality effects have been found using a dichotic target detection task in a recent experiment using word stimuli pronounced with an emotional component. The present study tested the hypothesis that the magnitude and reliability of the laterality effects would increase with the removal of the emotional component and variations…

Evidence has been accumulating that shows the promise of multidimensional conceptualizations of anxiety in investigating the effects of anxiety on different aspects of human behavior and intellectual performance. In view of the lack of an L2 writing anxiety scale explicitly developed from a multidimensional perspective, this study aims to develop…

People have unique ways of learning, which may greatly affect the learning process and, therefore, its outcome. In order to be effective, e-learning systems should be capable of adapting the content of courses to the individual characteristics of students. In this regard, some educational systems have proposed the use of questionnaires for…

Students' scores on questionnaires concerning their approaches to studying in higher education exhibit reasonable stability over time, moderate convergent validity with their scores on other questionnaires, and reasonable levels of discriminating power and criterion-related validity. Nevertheless, the internal consistency of the constituent scales…

Background: The construct of quality of life (QoL) has been the focus of a great deal of recent research and has been operationalized in the assessment of the effectiveness of biomedical and rehabilitative interventions. Consequently, the effective measurement of QoL has become a relevant issue. QoL assessment should take account of both objective…

A major determinant of the success of educational intranet sites is their usability. In addition to measures of task performance and navigation behavior, psychometric instruments are used to evaluate usability and the quality of human-computer interaction more generally. However, there is a lack of validated instruments for the evaluation of…

This article discusses issues related to the development and dissemination of evidence-based assessment strategies for anxiety disorders and associated problems. It begins with a review of the criteria that should be considered when determining whether particular assessment procedures are evidence-based. These include such factors as reliability,…

The present study, based on three samples of college students totaling 1,832 participants, resulted in the conclusion that a 5-level response continuum for the short form of the Career Decision Self-Efficacy Scale (CDSE) proved at least as reliable and valid as the 10-level continua used in normative studies. Values of coefficient alpha ranged…
