E-book as facilitator of vocabulary acquisition: support of adults,dynamic dictionary and static dictionary

We investigated the effects of three facilitators: adults’ support, dynamic visual vocabulary support and static visual vocabulary support on vocabulary acquisition in the context of e-book reading. Participants were 144 Israeli Hebrew-speaking preschoolers (aged 4–6) from middle SES neighborhoods. The entire sample read the e-book without a dictionary once, and was pretested on receptive word comprehension, expressive word explanation and word production in story retelling. The sample was then randomly divided into four groups, each reading an e-book three times, with: (1) adults’ vocabulary support; (2) dynamic visual dictionary support; (3) static visual dictionary support; or (4) without support. The participants were then posttested on the same measures. Children’s progress in all measures was dependent on group, with adults’ support appearing as most effective, dynamic dictionary as second, static dictionary as third, and no support as least effective. However, the gains differed significantly only between some of the groups, but were always significantly different between the group given adults’ support and the control group which was given no support. We conclude that e-books can be used effectively to facilitate word meaning acquisition at different levels. This contribution can be augmented by adults’ support and dynamic dictionary support.     

Do null phonemic masking effects reflect strategic control of phonology?

Verstaen, Humphreys, Olson and D'Ydewalle [(1995) Journal of Memory and Language, 34, 335–356] reported null phonemic masking effectswith homophone targets under conditionsdiscouraging reliance on phonology. Theyattributed these null effects to the absence ofreliance on phonology, concluding that relianceon phonology may be strategically controlled. Two studies using Verstaen et al.'s methodoccasionally replicate these null phonemicmasking effects, but challenge theirinterpretation. The emergence of null phonemicmasking effects was unrelated to the strategymanipulation. Conversely, evidence forphonology emerged in homophone errorsregardless of the strategy manipulation anddespite null phonemic masking effects. Ourfindings reflect an inherent instability in theperception of homophones. We demonstrate thatthis instability is directly due to reliance onphonology, rather than to its control.     

When Sociocognitive Transaction among Peers Fails: The Case of Misconceptions in Science

The effect ofsociocognitive transaction among peers on cognitive change was analyzed. Transaction concerned the concept of speed applied to 2 problems: a Piagetian problem and a parallel problem evoking a misconception. The effect of transaction, intended to evoke inter- and intrapersonal conflicts, was compared to two other treatments: taking a multiple choice test aimed to raise intrapersonal conflict and no intervention. A total of 360 sixth, eighth, and tenth graders participated. Following treatments, subjects mainly progressed on the Piagetian problem and mainly regressed on the problem evoking the misconception. Transaction had a beneficial effect on the former problem, encouraging progress and discouraging regression relatively to other treatments. It had a bidirectional effect on the latter problem, encouraging both progress and regression. Cognitive change following transaction was related to level of reasoning on speed during transaction. Inter- and intrapersonal conflicts evoked by transaction resulted in different changes in the 2 problems: Interpersonal conflict increased intrapersonal conflict on both, but the degree of intrapersonal conflict was related to change on the latter problem only, with greater conflict evoking greater change, mainly regressive. Results cast doubt on Piagetian assumptions concerning the role of conflict in cognitive development.     

Higher education and attainment of policy goals: Interpretations for efficiency indicators in Israel

This study concerns identification of policy aims and goals in Israeli Higher Education (HE) and an analysis of efficiency indicators to determine the extent and nature of HE policy goal attainment at the Israeli universities. Overall, these indicators, be they quantitative or qualitative, point to major developments in the Israeli HE system in both national and international comparative terms. The aims and related efficiency performance indicators identified and used in this study are normative and their analysis follows conceptualizations of efficiency assessment. They are in line with orientations of quality as bound up with values and fundamental aims relating to fitness for purpose (Ball 1985; Williams 1991; Barnett 1989, 1992; vanVught 1994) and pertain mainly to the individual universities' perceptions and priorities. The analysis model also adopts conceptual approaches used in studies of HE quality by the Planning and Budgeting Committee of the Israeli HE Council, as well as those conducted in England, Scotland, and the Netherlands, and by the OECD. As such, the analysis model as well as the findings identified in this study lend themselves to comparative HE policy analysis in a global perspective.     

Editors’ Note

The notion that students come to science courses with misconceptions has become quite widely accepted by those who follow or participate in education research. DiSessa and his colleagues (diSessa, 1988, 1993; Smith, diSessa, &; Roschelle, 1993/1994) have challenged the theoretical and empirical validity of this perspective and offered an alternative account of cognitive structure in phenomenological primitives or p-prims. The purpose of this article is to further clarify and contrast the two accounts: in particular, to consider their utility and generativity as conceptual tools for teachers. How may each perspective influence instructional perceptions and intentions? The article recounts a discussion about forces and motion from a high-school physics class, analyzes how a teacher may perceive students' participation in that discussion from either perspective, and considers what, based on those perceptions, the teacher may see as tasks for instruction.     

Online newspapers in the U.S.: Perceptions of markets,products, revenue,and competition

The market position of Public Service Media (PSM) and the programming and services provided have for years been the object of academic media research. Relatively little has however been written about the way the PSM corporations are managed. The article presents a number of reasons why media management researchers should add this area to their field of study. Not only are the managers of PSM corporations in great need of scholarly inspiration from outside. Even more important from an academic perspective is the fact that PSM provides management researchers with a sample of reasonably comparable cases of media companies and managers exposed to radical and very similar changes in their operational environment.     

Effects of radiant heat exposure on pacing pattern during a 15-km cycling time trial

Abstract

The goal of this study was to investigate the effects of different durations of skin temperature manipulation on pacing patterns and performance during a 15-km cycling time trial. Nineteen well-trained men completed three 15-km cycling time trials in 18°C and 50% relative humidity with 4.5-km (short-heat), 9.0-km (long-heat) or without (control) radiant heat exposure applied by infrared heaters after 1.5 km in the time trial. During the time trials, power output, mean skin temperature, rectal temperature, heart rate and rating of perceived exertion were assessed. The radiant heat exposure resulted in higher mean skin temperature during the time trial for short-heat (35.0 ± 0.6°C) and long-heat (35.3 ± 0.5°C) than for control (32.5 ± 1.0°C; P < 0.001), whereas rectal temperature was similar (P = 0.55). The mean power output was less for short-heat (273 ± 8 W; P = 0.001) and long-heat (271 ± 9 W; P = 0.02) than for control (287 ± 7 W), but pacing patterns did not differ (P = 0.55). Heart rate was greatest in control (177 ± 9 beats · min^?1; P < 0.001), whereas the rating of perceived exertion remained similar. We concluded that a radiant heat exposure and associated higher skin temperature reduced overall performance, but did not modify pacing pattern during a 15-km cycling time trial, regardless of the duration of the exposure.     

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.     

CREATIVITY IN ADULTHOOD AND OLD AGE: AN EXPLORATORY STUDY

The purpose of this study was to explore the creative process and creative products across the adult life span. The subjects were 61 women, ages 20 to 83 years, who were comparable in intelligence, education, and interest in writing. They completed a creative writing project and took three standardized creativity tests and two intelligence subtests. Both quantitative and qualitative differences were found favoring young adults. Predictive but not construct validity was demonstrated for the creativity tests with this population of young and old adults. Both methodological constraints and the ecological validity of these measures of creativity are discussed.
