Third, fifth, and seventh graders, most of them Mexican-American, were exposed to an empirically based and culturally sensitive AIDS curriculum designed to replace their intuitive theories with a coherent, scientific account of the causal processes that lead from risk behavior to AIDS symptomatology. Compared to students in control classes, experimental students knew more about AIDS risk factors and AIDS generally, displayed more conceptual understanding of the causes of AIDS and flu, and were more willing to interact with people who have AIDS (although not less worried about AIDS) at posttest and typically at follow-up 10–11 months later. The findings point to the potential value of adopting an intuitive theories approach in assessing and modifying children's concepts of health and illness and suggest, contrary to Piagetian formulations, that even relatively young children can, with appropriate instruction, grasp scientific theories of disease.  相似文献   

The Measurement of Postures     

Olga Andersen Buhl  Warren P. Morrill M.D 《Research quarterly for exercise and sport》2013,84(3):518-527

Abstract

Thirty-three college men doing the toe-touch test were used as subjects to ascertain the relative contribution of the back and hamstring muscles to hip joint flexibility. The subjects, performing six tests over a 5-week period, were photographed during each of their tests. Anthropometric measurements were taken prior to testing to determine if there was any relationship to flexibility. Making use of concentric circles and marking reference points on the subject prior to testing, it was possible to ascertain the curvature of the back, the angle of straight back flexibility, and the angle of bent back flexibility.

Results indicate that the extensibility of the hamstring muscles appeared to be one of the main contributing factors to hip joint flexion, and since the warm-up did not affect the flexibility of the back, one might conclude that the back made no increased contribution to hip joint flexion, as measured in this study. There was no significant relationship to the angle of bent back flexibility.  相似文献   

Causal relationships of sport and exercise involvement with goal orientations,perceived competence and intrinsic motivation in physical education: A longitudinal study     

Athanasios Papaioannou  Evaggelos Bebetsos  Yannis Theodorakis  Triantafyllos Christodoulidis  Olga Kouli 《Journal of sports sciences》2013,31(4):367-382

Abstract

Little information exists about the causal relationships of sport and exercise participation with goal orientations, perceived athletic competence and intrinsic motivation in physical education. A longitudinal study was conducted involving 882 Greek students who completed questionnaires on three occasions: 3 – 5 weeks into the academic year, 3 – 6 weeks before the end of the academic year, and 7 months later. The data were analysed using structural equation models, controlling for age. Task orientation and intrinsic motivation in physical education at the beginning of the academic year predicted sport and exercise participation 7 and 14 months later. Perceived athletic competence both at the beginning and end of the academic year predicted sport and exercise participation 7 and 14 months later, while ego orientation did not predict sport and exercise involvement at either time. Previous sport and exercise participation had positive effects on task orientation and perceived athletic competence 3 – 6 weeks before the end of the academic year and predicted all cognitive-affective constructs 7 months later. These results imply that the cultivation of task orientation, intrinsic motivation in physical education and perceived athletic competence will help to promote sport and exercise participation in adolescence.  相似文献   

The Impact of Model Misspecification on Parameter Estimation and Item‐Fit Assessment in Log‐Linear Diagnostic Classification Models     

Olga Kunina‐Habenicht  André A. Rupp  Oliver Wilhelm 《Journal of Educational Measurement》2012,49(1):59-81

Using a complex simulation study we investigated parameter recovery, classification accuracy, and performance of two item‐fit statistics for correct and misspecified diagnostic classification models within a log‐linear modeling framework. The basic manipulated test design factors included the number of respondents (1,000 vs. 10,000), attributes (3 vs. 5), and items (25 vs. 50) as well as different attribute correlations (.50 vs. .80) and marginal attribute difficulties (equal vs. different). We investigated misspecifications of interaction effect parameters under correct Q‐matrix specification and two types of Q‐matrix misspecification. While the misspecification of interaction effects had little impact on classification accuracy, invalid Q‐matrix specifications led to notably decreased classification accuracy. Two proposed item‐fit indexes were more strongly sensitive to overspecification of Q‐matrix entries for items than to underspecification. Information‐based fit indexes AIC and BIC were sensitive to both over‐ and underspecification.  相似文献   

A longitudinal study of handwriting skills in pre-schoolers: the acquisition of syllable oriented programming strategies     

Olga Soler Vilageliu  Sonia Kandel 《Reading and writing》2012,25(1):151-162

Previous studies have shown the relevance of the syllable as a programming unit in handwriting production, both in adults and elementary school children. This longitudinal study focuses on the acquisition of writing skills in a group of preschoolers. It examines how and when the syllable structure of the word starts regulating motor programming in handwriting. Eighteen five year old preschoolers copied six-letter Catalan words (disyllabic and trisyllabic) on a digitiser at three different times over the academic year (January, March, and May). The words were written in uppercase letters. We measured the duration of the inter-letter intervals (ILI) to gather information on the timing of motor programming. The results indicated that from January to March the children were mostly focused on movement proficiency. The results also showed different profiles of ILI duration for the two types of words over the three sessions. For disyllabic words, the syllable regulated movement programming in January; for trisyllabic words, this happened in March. This suggests that the syllable already plays a role in the programming of handwriting movements in kindergarten.  相似文献

The pedagogical value of art and music in the past and the present     

Olga Denac 《美中教育评论》2009,6(10):54-60

Pedagogical theory and research practice tend to confine themselves to study the cognitive aspect of a child＇s personality and to focus on his/her productivity, while forgetting about other dimensions. The ability to experience artistic contents and the creative capacity of our society are decreasing. People are in a continuous search for spiritual balance and therefore the task of the contemporary school is to help people get out of this crisis and pay more attention to the realization of educational tasks and goals as well as individual school subjects. Art has always played the role of purposefully influencing the experiencing, feeling, creating and enjoying of beautiful things. It therefore provides a counterbalance to the rationalized world of today. Especially music plays a special role in all periods and all human societies, however, not because it encourages various experiences or notions in the listener or a pleasant atmosphere, but because it presents a challenge to the development of spiritual perception that does not occupy an important, enough place in the present school system. Based on different historical understandings of the pedagogical value of music, the author tries to determine what pedagogical value was ascribed to music in the past and what pedagogical value it is being ascribed today  相似文献   

Underemployment and employment among young workers and the business cycle in Spain: the importance of education level and specialisation     

Juan Acosta-Ballesteros  Olga María Rodríguez-Rodríguez 《Journal of Education & Work》2018,31(1):28-46

The objective of this paper is to identify the effect of education on young workers’ time-related underemployment as well as analysing whether education has been a defence mechanism against the recent crisis. Especially relevant is the analysis regarding field of study, which has not been addressed in the underemployment literature. Using data from the Spanish Labour Force Survey 2006–2014, bivariate probit selection models are estimated for three different periods. This methodology enables to analyse the evolution of underemployment among young people, simultaneously considering their probability of employment. The results indicate that underemployment is negatively related to education level for each period and tertiary education has smoothed the negative effect of the recession. Moreover, those specialisations that provide students with specific and work-oriented skills (sciences, technology and health) help workers avoid underemployment and enable them to handle the recession better. Conversely, more generally oriented fields (education, and arts and humanities) are associated with a higher probability of underemployment. Similar patterns have been found regarding unemployment, indicating education plays a similar role in both working time shortages.  相似文献   

Lexical cohesion and term proximity in document ranking     

Olga Vechtomova  Murat Karamuftuoglu 《Information processing & management》2008

We demonstrate effective new methods of document ranking based on lexical cohesive relationships between query terms. The proposed methods rely solely on the lexical relationships between original query terms, and do not involve query expansion or relevance feedback. Two types of lexical cohesive relationship information between query terms are used in document ranking: short-distance collocation relationship between query terms, and long-distance relationship, determined by the collocation of query terms with other words. The methods are evaluated on TREC corpora, and show improvements over baseline systems.  相似文献   

From centrally mandated to locally demanded service: the Russian case   总被引：1，自引：0，他引：1  

Olga B. Bain  Iouri A. Zakharov  Natalia B. Nosova 《Higher Education》1998,35(1):49-67

This paper first highlights recent changes in the environment of Russian universities and considers how institutions of higher education (HEIs) are responding to the challenges and opportunities of the new environment through drawing on case studies of three relatively successful universities. Secondly, it considers how the recent changes, by pushing universities to seek new and more locally based sources of revenue, have lead to a significant modification of the concept and practice of university service. While the Russian university in the Soviet period was expected by virtue of the collectivist ideology to supply service to the people, these activities tended to come from above as gifts to society. In the new environment, service is both increasing and is becoming more sensitive to local needs. The overall effect may be to energize the Russian university, but there is considerable concern that it may at the same time erode the long-standing tradition of intellectual excellence.  相似文献
