Effects of Aerobic Exercise on Overweight Children's Cognitive Functioning

The study tested the effect of aerobic exercise training on executive function in overweight children. Ninety-four sedentary, overweight but otherwise healthy children (mean age = 9.2 years, body mass index ? 85th percentile) were randomized to a low-dose (20 min/day exercise), high-dose (40 min/day exercise), or control condition. Exercise sessions met 5 days/week for 15 weeks. The Cognitive Assessment System (CAS), a standardized test of cognitive processes, was administered individually before and following intervention. Analysis of covariance on posttest scores revealed effects on executive function. Group differences emerged for the CAS Planning scale (p = .03). Planning scores for the high-dose group were significantly greater than those of the control group. Exercise may prove to be a simple, yet important, method of enhancing aspects of children's mental functioning that are central to cognitive and social development.     

Games and ideal playgrounds

Even though many sport philosophers have worked to delineate clear definitions of play and games, typical language usage often conflates the two phenomena and even provides an undue normative bias toward games as play. In this paper, I argue that a better understanding of games and ideal playgrounds is required to alleviate this normative bias. To carry out this argument, I first examine previous definitions of play and games and how the concepts are often conflated. Secondly, I provide a definition of ideal playgrounds using prior philosophy on play and human conventions. Third, I present an analysis that examines how both game and non-game activities can act as ideal playgrounds. Finally, I argue that changes to the way we use language can help to alleviate this problem.     

Collateral Information for Equating in Small Samples: A Preliminary Investigation

This article describes a preliminary investigation of an empirical Bayes (EB) procedure for using collateral information to improve equating of scores on test forms taken by small numbers of examinees. Resampling studies were done on two different forms of the same test. In each study, EB and non-EB versions of two equating methods—chained linear and chained mean—were applied to repeated small samples drawn from a large data set collected for a common-item equating. The criterion equating was the chained linear equating in the large data set. Equatings of other forms of the same test provided the collateral information. New-form sample size was varied from 10 to 200; reference-form sample size was constant at 200. One of the two new forms did not differ greatly in difficulty from its reference form, as was the case for the equatings used as collateral information. For this form, the EB procedure improved the accuracy of equating with new-form samples of 50 or fewer. The other new form was much more difficult than its reference form; for this form, the EB procedure made the equating less accurate.     

Teaching and learning by videoconferencing at the University of Ulster

The Open University has developed an array of tutorial and advisory services for its students over 16 years. These have been reviewed regularly for their academic appropriateness and effectiveness. More recently, urgent reductions in services have taken place, in response to financial restraints. During 1985, Mary Thorpe and colleagues in the Student Research Centre, the Institute of Educational Technology conducted in‐depth interviews with students and staff to explore their perceptions of studying with the Open University.

DESIGNING A MULTI-DISCIPLINARY GERIATRICS HEALTH PROFESSIONAL MENTORING PROGRAM

This paper describes a Geriatric Health Professionals Mentoring Program designed to address recruitment and retention of health professionals in geriatrics and gerontology. The training provided information on the mentoring process, negotiating mentoring agreements, and coaching mentees. The evaluative framework described examines: (a) the effects of mentoring, (b) reactions of mentors and mentees, and (c) the effect of intervening variables. Trained mentors expressed satisfaction with the program and were comfortable about general mentoring but less confident about specific guidance for mentees. A cadre of mentors can be successfully trained to assist geriatric health professionals to better care for older Americans.     

Validation of the Attitude-Older Adult and Aging-Visual Analogue Scales (At-O-A)

ABSTRACT

Occupational therapy programs have been developed in order to promote health in older adults. However, no published studies have yet been identified for the Spanish population. This study explores the benefits of an occupational therapy health promotion program called EnvejeHaciendo (AgeDoing). The study was conducted with 15 elderly Spanish adults, examining health perception and meaningful occupational participation using the Model of Human Occupation, as well as the pedagogical methodology See, Judge, Act. The results showed an increase in the perception of health with reference to social functioning and the number of roles in which the participants wanted to get involved in the future. The participants changed their own negative perception of elderly people, they adapted to the changes provoked by aging, and they got involved in meaningful activities such as physical exercise or social activities. This program allowed participants to engage in meaningful occupations with other people and to increase perceived health status through raising awareness of difficulties.     

‘We are family’: Māori success in foundation programmes

This paper considers the question: What constitutes an optimal learning environment for Māori learners in foundation programmes? Using Kaupapa Māori methodology, nearly 100 adult Māori (Indigenous) students in Aotearoa/New Zealand were interviewed from a range of tertiary providers of foundation programmes. State-funded foundation programmes that scaffold adults into tertiary education are a partial response to Ministry of Education concerns about unsatisfactory high school statistics for some sections of the community. Connecting with Māori voices enabled the researchers to gain a deeper awareness of the reality of study experiences for these adult learners. It is argued that academic participation and success for adult Māori learners is increased when the learning and teaching environment mirrors the connectedness and belonging of a whānau (family) environment.     

The Circle-Arc Method for Equating in Small Samples

This article suggests a method for estimating a test-score equating relationship from small samples of test takers. The method does not require the estimated equating transformation to be linear. Instead, it constrains the estimated equating curve to pass through two pre-specified end points and a middle point determined from the data. In a resampling study with two test forms that differed substantially in difficulty, the proposed method compared favorably with other equating methods, especially for equating scores below the 10th percentile and above the 90th percentile.     

Integrating problem- and project-based learning opportunities: assessing outcomes of a field course in environment and sustainability

Improving student competencies to address sustainability challenges has been a subject of significant debate in higher education. Problem- and project-based learning have been widely celebrated as course models that support the development of sustainability competencies. This paper describes a course developed for a professional Master’s program in environment and sustainability that employs such a model. Additionally, the course was designed to offer value-added opportunities by introducing attributes of interdisciplinary training, service learning, academic research, and professional practice. Results from the course assessments by students, faculty, community clients and organizational partners show this model provided a range of learning, professional and practical outcomes for course partners. The value-added benefits include strengthening sustainability competencies and professional skills for students; longitudinal research opportunities for teaching faculty; real-time assessments of farming practices for community clients; and a heightened regional profile for the non-profit biosphere reserve organization supporting course delivery.
