Estimating parallel form reliability from one administration of a criterion-referenced test: A computer program for practitioners

Reliability of a criterion-referenced test is often viewed as the consistency with which individuals who have taken two strictly parallel forms of a test are classified as being masters or nonmasters. However, in practice, it is rarely possible to retest students, especially with equivalent forms. For this reason, methods for making conservative approximations of alternate form (or test-retest “without the effects of testing”) reliability have been developed. Because these methods are computationally tedious and require some psychometric sophistication, they have rarely been used by teachers and school psychologists. This paper (a) describes one method (Subkoviak's) for estimating alternate-form reliability from one administration of a criterion-referenced test and (b) describes a computer program developed by the authors that will handle tests containing hundreds of items for large numbers of examinees and allow any test user to apply the technique described. The program is a superior alternative to other methods of simplifying this estimation procedure that rely upon tables; a user can check classification consistency estimates for several prospective cut scores directly from a data file, without having to make prior calculations.     

Beyond Performance: A Motivational Experiences Model of Stereotype Threat

The contributing role of stereotype threat (ST) to learning and performance decrements for stigmatized students in highly evaluative situations has been vastly documented and is now widely known by educators and policy makers. However, recent research illustrates that underrepresented and stigmatized students’ academic and career motivations are influenced by ST more broadly, particularly through influences on achievement orientations, sense of belonging, and intrinsic motivation. Such a focus moves conceptualizations of ST effects in education beyond the influence on a student’s performance, skill level, and feelings of self-efficacy per se to experiencing greater belonging uncertainty and lower interest in stereotyped tasks and domains. These negative experiences are associated with important outcomes such as decreased persistence and domain identification, even among students who are high in achievement motivation. In this vein, we present and review support for the Motivational Experience Model of ST, a self-regulatory model framework for integrating research on ST, achievement goals, sense of belonging, and intrinsic motivation to make predictions for how stigmatized students’ motivational experiences are maintained or disrupted, particularly over long periods of time.     

Internationalisation of higher education: integrating international students into Canadian academic environment

Fuelled by globalisation, the internationalisation of higher education in Canada is happening at a rapid pace. One manifestation of internationalisation is the increasing enrolment of international graduate students in Canadian institutions. Many of these students face challenges and barriers in integrating into Canadian academic environments including isolation, alienation, marginalisation and low self-esteem. This case study investigates a programme at a large Canadian university intended to help international graduate students with their adaptation to an unfamiliar academic environment. The research shows that the programme was successful in creating a transnational learning space where international students developed a sense of belonging, increased cross-cultural understanding and raised awareness about global issues. More importantly, it helped international students with their integration into a Canadian learning community. The findings have important implications for the development of programmes to provide appropriate levels of support for international students and for building internationally inclusive campuses.     

Validity of the VmaxST portable metabolic measurement system

Abstract

The aim of this study was to assess and compare the validity of the portable VmaxST telemetry metabolic measurement device with that of a standard measurement system (Vmax29). Thirty asymptomatic, moderately active males provided written, informed consent and completed two maximal graded treadmill exercise tests (Bruce) using the VmaxST and the Vmax29 metabolic measurement systems. Tests were performed in random order on separate days to obtain peak values for time to exhaustion, heart rate, systolic and diastolic blood pressure, oxygen consumption ([Vdot]O₂), carbon dioxide production ([Vdot]CO₂), ventilation ([Vdot] _E), and respiratory exchange ratio (RER). Multivariate analysis of variance revealed no significant main effect (P = 0.88) between the two systems across any variable, suggesting similar measurement capabilities between the two systems. Linear regression analyses revealed moderate to high coefficients of determination for [Vdot]O₂ (r ² = 0.99), [Vdot]CO₂ (r ² = 0.99), [Vdot] _E (r ² = 0.99), and RER (r ² = 0.89). Furthermore, Bland-Altman analyses demonstrated that the VmaxST yielded similar values to the Vmax29, suggesting good agreement between the two systems. Agreement was confirmed when the differences between the methods resulted in a small range as identified by the 95% limits of agreement. Findings from the current study confirm that the VmaxST is a valid device for measuring metabolic and physiological variables during exercise within a controlled laboratory setting.     

The Role of Sport as a Social Status Determinant for Children

The purpose of this study was to examine the role of sport as a social status determinant among racially diverse children. Participants were 1,233 fourth- to seventh-grade children. Results indicated there were gender, grade, and racial differences for the selection of social status determinants. Boys placed more importance than girls on being good at sports and wealth. Girls placed more importance than boys on getting good grades and being attractive. Fourth- and fifth-grade students ranked getting good grades as most important, while sixth- and seventh-grade students ranked being attractive as most important. Non-Hispanic Caucasian students ranked being good at sports and being attractive as most important, while African American students ranked getting good grades and wealth as most important.     

Academic Libraries and Mobile Devices: User and Reader Preferences

The authors surveyed 250 students, faculty, alumni, administrators, and staff about how they use mobile devices, if at all, to access a university library. Fifty percent of respondents reported that they used their mobile devices to access the library—primarily the catalog and the research databases; however, usability hindered accessing other desired services. These results have implications for library administrators with respect to making decisions about App choices, the advertisement of services, and the transition to e-collections.

A new chemotherapeutic investigation: Piracetam effects on dyslexia

Piracetam, a new drug which is thought to enhance learning and memory consolidation, was given in a 3300 mg daily dose to half of a group of fifty-five (55) dyslexic boys aged eight to thirteen years in a twelve week, double-blind, placebo controlled study. All subjects met stringent criteria, including: normal intelligence, normal educational opportunities, no severe emotional problems, no neurological handicaps, good physical health, not taking other psychotropic medication, and scoring at least 1 1/2 years below their mental age equivalent on the Gilmore Oral Reading Test. The children’s perceptual, language, and memory skills were examined and their reading, spelling, and writing abilities were measured using standardized instruments. Compared to the placebo control group, individuals treated with Piracetam showed statistically significant improvements above their baseline scores on measures of effective reading accuracy and comprehension, reading speed, and writing accuracy. The medication was extremely well tolerated, and all medical examinations showed no untoward effects. These results encourage further study of Piracetam’s potential as an adjunct for the clinical remediation of dyslexia.
